If the temperature is read every 12 hours, then the eighth temperature reading will be taken at 11.15 pm three days after the first reading.
What is temperature?Temperature is a measure of the degree of hotness or coldness of a substance or object, typically measured using a thermometer in degrees Celsius or Fahrenheit.
If the temperature is read every 12 hours, then the time interval between two consecutive temperature readings is 12 hours.
To find the time of the eighth temperature reading, we need to add 12 hours for each of the previous seven temperature readings:
First reading: 11.15 am
Second reading: 11.15 am + 12 hours = 11.15 pm
Third reading: 11.15 pm + 12 hours = 11.15 am (next day)
Fourth reading: 11.15 am (next day) + 12 hours = 11.15 pm (next day)
Fifth reading: 11.15 pm (next day) + 12 hours = 11.15 am (two days after the first reading)
Sixth reading: 11.15 am (two days after the first reading) + 12 hours = 11.15 pm (two days after the first reading)
Seventh reading: 11.15 pm (two days after the first reading) + 12 hours = 11.15 am (three days after the first reading)
Eighth reading: 11.15 am (three days after the first reading) + 12 hours =
11.15 pm (three days after the first reading)

In the diagram provided, line l is parallel to line m. Select which of the following statements could be used to prove that the interior angles of a triangle have a sum of 180°. You may choose more than one correct answer. m 4 + m 5 + m 6 = 180. 1 and 4 are alternate interior angles. m 5 = m 3 + m 2. m 5 + m 1 = 180.
m4 + m5 + m6 = 2m4 + m5 = 180, which proves that the interior angles of a triangle have a sum of 180 degrees.
What is interior angles of a triangle?Interior angles of a triangle are the angles formed inside a triangle at each of its vertices. The sum of these angles is always 180 degrees in a Euclidean plane.
This statement can be used because lines l and m are parallel, which means that m4 and m6 are corresponding angles and are congruent. This means that m4 = m6. Also, m5 and m4 are alternate interior angles, which means that they are congruent as well.
we can substitute m6 with m4 in the first equation to get:
m4 + m5 + m4 = 180
2m4 + m5 = 180
Therefore, the equation simplifies to:
2(180 - m5) + m5 = 180
360 - 2m5 + m5 = 180
m5 = 180 - 360 + 2m5
m5 = 2m5 - 180
m5 = 180

144 is 90% what is the other 10 percent
Answer:
the missing 10% of 144 is 16. The whole amount would be 144 + 16 = 160.
Step-by-step explanation:
To find the missing 10%, you can use the fact that 100% is equal to the whole amount, and set up a proportion:
90/100 = 144/x
Simplifying this proportion, you can cross-multiply:
90x = 100 * 144
Then, you can solve for x:
x = (100 * 144) / 90
x = 160
Therefore, the missing 10% of 144 is 16. The whole amount would be 144 + 16 = 160.

How to solve this problem
On January 1, 2012, Chan Enterprises borrowed $100,000 from a bank on a three-year mortgage with an interest rate of 5% per year. On December 30, 2012, Chan paid the bank $36,721. Chan uses US GAAP to prepare its financial statements.
Which of the following items would be decreased by the mortgage payment? (check all that apply)
Answer:
The following items would be decreased by the mortgage payment:
Notes payable (or long-term debt)
Interest expense
Cash (or checking account, or bank account)
Step-by-step explanation:
The mortgage payment has two components: a principal payment and an interest payment. The principal payment reduces the amount of the loan outstanding, while the interest payment represents an expense for the borrower.
Under US GAAP, the mortgage liability balance on the balance sheet would be decreased by the principal portion of the mortgage payment, as the liability represents the amount of the loan outstanding. The interest expense on the income statement would also be decreased by the interest portion of the mortgage payment, as this represents the cost of borrowing the money.
Therefore, the items that would be decreased by the mortgage payment are:
Mortgage liability on the balance sheet (by the principal portion of the payment)
Interest expense on the income statement (by the interest portion of the payment)
The amount of money you pay for your mortgage, which is $36,721, would become smaller for these things:
Which of the following items would be decreased by the mortgage payment?Loan Payable: The amount of money owed on a loan goes down when a payment is made. So, the amount of money owed for the loan would go down by $36,721.
Interest Expense: According to the rules for accounting in the US, a part of each payment for a mortgage goes towards paying the interest.
Principal: The amount of money you still owe on the loan gets smaller when you make a mortgage payment. So, the amount of money the Principal decreases by is $36,721.
It's important to know that the cost of borrowing money and the amount paid back can be grouped together in financial statements as "Loan Payment" or "Loan Repayment" without showing separate lines for interest and principal. This depends on how Chan Enterprises chooses to present the information.

The perimeter of the triangle JKL, obtained using the two tangent theorem, is 138 units
What is the two tangent theorem?The two tangent theorem states the segments from the circle to the point at which two tangents to the circle meet are congruent.
The two tangent with common external point theorem indicates that the relationships between the lengths of the segments are;
5·x - 8 = 8·x - 35
8·x - 35 = 5·x - 8
8·x - 5·x = 35 - 8 = 27
3·x = 27
x = 27/3 = 9
x = 97·y - 9 = 2·y + 11
7·y - 2·y = 11 + 9 = 20
5·y = 20
y = 20/5 = 4
y = 4LO = 32 - (2·y + 11)
Therefore; LO = 32 - (2 × 4 + 11) = 13
LO = 13The two tangents theorem, indicates that we get;

Explain equation.The foundation of a model of linear regression is the equation y=mx+b. The inclination is B, and the y-intercept is m. Although it is true that y and y are separate parts, the the above sentence is frequently referred to as a "mathematics problem with two variables". Only two factors are present in bivariate linear equations. There are no unambiguous answers to the application domains of linear equations.
Here,
=> 5y + 2x = 2 ...(1)
=> x = -2y + 3 ...(2) (2)
Equation (1) is completed by substituting the value of x from equation (2):
=> 5y + 2(-2y + 3) = 2
When we simplify the previous solution, we get:
=>y = 4/3
Adding the value of x to equation (2) now yields:
=> x = -2(4/3) + 3
When we simplify the previous solution, we get:
=> x = 2/3
As a result, the answer is (x, y) = (2/3, 4/3.
=> y + 2x = 9 ...(3)
=> y - 3x = -1 ...(4)
Equation (3) by 3 and Equation (4) by 2 are multiplied to yield:

Equations (5) and (6) combined give us:
=>5y = 25
Consequently, x = 5.
Adding the number of y to equation (3) yields the following results:

What is surface area
Given that three factors are given and the surface area is required, this means that we are dealing with a three-dimensional shape. Where the above is a rectangular prism, the surface area = 118 In².
What is the explanation for the above response?
Surface area is the measure of the total area that the surface of a three-dimensional object occupies.
To calculate the surface area of an object, you need to add up the areas of all its faces. The formula for finding the surface area of a rectangular prism, which has three pairs of congruent rectangular faces, is:
Surface area = 2(lw + lh + wh)
where l, w, and h are the length, width, and height of the rectangular prism, respectively.
So, if we have a rectangular prism with the following dimensions:
Length (l) = 3.5 inches
Width (w) = 4 inches
Height (h) = 6 inches
The surface area can be calculated as follows:
Surface area = 2(lw + lh + wh)
= 2(3.5 x 4 + 3.5 x 6 + 4 x 6)
= 2(14 + 21 + 24)
= 2(59)
= 118In²

You deposit $6000 in an account earning 6% interest compounded quarterly. How much will you have in the account in 15 years? Round your answer to the nearest cent.
Step-by-step explanation:
The formula to calculate the future value of a present value deposit with compounding interest is:
FV = PV × (1 + r/n)^(n*t)
Where:
PV = Present Value (the initial deposit)
r = Annual interest rate (as a decimal)
n = Number of compounding periods per year
t = Number of years
Using this formula, we can calculate the future value of the $6000 deposit after 15 years:
PV = $6000
r = 6% = 0.06
n = 4 (compounded quarterly, i.e. 4 times per year)
t = 15 years
FV = $6000 × (1 + 0.06/4)^(4*15)
FV = $6000 × 1.458^60
FV = $6000 × 6.2565
FV = $37,539.00
Therefore, the future value of the $6000 deposit after 15 years with quarterly compounding at 6% interest rate is $37,539.00.

Ingrum Corporation produces and sells two products. In the most recent month, Product R38T had sales of $33,000 and variable expenses of $8,840. Product X08S had sales of $54,000 and variable expenses of $32,050. The fixed expenses of the entire company were $36,130. The break-even point for the entire company is closest to:
Answer:
Therefore, the break-even point for the entire company is approximately 0.784 or 78.4%.
Step-by-step explanation:
To calculate the break-even point, we need to find the total contribution margin, which is the difference between the total sales revenue and total variable expenses.
For Product R38T, the contribution margin is $33,000 - $8,840 = $24,160.
For Product X08S, the contribution margin is $54,000 - $32,050 = $21,950.
The total contribution margin for both products is $24,160 + $21,950 = $46,110.
To calculate the break-even point, we divide the total fixed expenses by the total contribution margin:
Break-even point = Total fixed expenses / Total contribution margin
= $36,130 / $46,110
= 0.784
Therefore, the break-even point for the entire company is approximately 0.784 or 78.4%.

what is the anwser to finding the radius
The radius of the circle is r = 3.75
What is the radius of a circle?The radius of a circle is the distance from its center to its circumference.
To find the radius of the circle, we see that there is a right-angle triangle there. So, using Pythagoras' theorem, we have that
AC² = AB² + BC²
(6 + r)² = 9² + r²
Expanding the brackets, we have that
36 + 12r + r² = 81 + r²
Cancelling out r², we have that
36 + 12r = 81
Subtracting 36 from both sides, we have that
12r = 81 - 36
12r = 45
r = 45/12
r = 15/4
r = 3.75
So, the radius is r = 3.75

A textbook store sold a combined total of 445 math and sociology textbooks in a week the number of math textbooks sold was 75 more than the number of sociology textbook sold how many textbooks of each type were sold
In respοnse tο the stated questiοn, we can state that Hence, 185 equatiοn textbοοks fοr sοciοlοgy and 185 + 75 = 260 fοr math were sοld.
What is equatiοn?An equatiοn is a mathematical assertiοn that establishes the equality οf twο expressiοns that are jοined tοgether by the equals sign ('='). Fοr example, 2x – 5 = 13.
2x-5 and 13 are examples οf expressiοns. The letter '=' cοnnects the twο expressiοns. A mathematical fοrmula is called an equatiοn if it cοntains twο algebraic expressiοns οn either side οf the equal sign (=). It shοws hοw the right and left fοrmulas are equivalent tο οne anοther. Any fοrmula will result in L.H.S. = R.H.S. (left side = right side).
Let's use variables tο reflect the quantity οf sοciοlοgy and math textbοοks that have been sοld.
Let x represent hοw many sοciοlοgy textbοοks were sοld.
Then, x + 75 math textbοοks wοuld have been sοld.
Since we are aware that 445 textbοοks were sοld in tοtal, we can cοnstruct the fοllοwing equatiοn:
x + (x + 75) = 445
Simplifying and finding x's value:
2x + 75 = 445
[tex]2x = 370 \sx = 185[/tex]
Hence, 185 textbooks for sociοlogy and 185 + 75 = 260 for math were sold.

Please help !! Find the slope of a line perpendicular to the line whose equation is 3x−y=6.
Fully simplify your answer.
Answer:
[tex]-\dfrac{1}{3}[/tex]
Step-by-step explanation:
Since this question is asking for only the slope of the perpendicular line it is fairly easy
if a line has a slope m then the slope of the perpendicular line is [tex]-\dfrac{1}{m}[/tex]
The given line is
[tex]3x - y = 6[/tex] [1]
To find the slope of this line, convert this into slope-intercept form:
[tex]y = mx + c[/tex]
In equation (1) subtract 3x from both sides
[tex]3x - 3x - y = -3x + 6[/tex]
- y = -3x + 6
multiply by - 1:
y = 3x - 6
Slope of line = 3
Slope of parallel line = [tex]-\dfrac{1}{3}[/tex]

1. Determine if the polygons are similar. Hint: theorems we learned to prove two triangles similar include AA, SAS and SSS. Are the triangles similar (yes or no)? yes
Triangle with smaller triangle inside H R J S T K 10 6 4.8 8
Work or explanation:
Which theorem can you use to prove the two triangles similar? SAS
Yes triangles are similar.
SAS theorem is used to prove triangles are similar.
Define Side-Angle-Side Similarity Criteria, or SASThe SAS similarity theorem states that if any two sides of the first triangle are exactly proportional to any two sides of the second triangle and the angle created by these two individual triangles is identical, then the two triangles must be similar. When we only know the length of two sides and the angle produced between those two sides in each triangle, this rule is often implemented.
ΔRST and ΔHJK triangles are similar.
According to the SAS theory,
∠ S=∠J (angles are equal)
SR/HJ=ST/JK
6/10=4.8/8.6=.6( both sides are proportional)
Triangles ΔRST and ΔHJK are hence identical.
Two triangles can be compared using the Side-Angle Theorem.
