Just onve more question
same as the other one
Answer:
x = 2
Step-by-step explanation:
4(5 - 2x) + 3 = 7
Distributive property , multiply (5-2x) by 4:
20 -8 x + 3 = 7
Combine like terms:
23 - 8x = 7
Inverse add and subtract:
23 - 7 - 8x + 8x = 7 - 7 + 8x
16 = 8x
Inverse divide:
16/8 = 8x/8
x = 2
Two angles have a supplementary relationship. The measure of one angle is 14°. What is the measure of the second angle?
Answer:
166°
Step-by-step explanation:
Supplementary angles have a sum of 180 degrees
That being said, we can find the measure of the missing angle by subtracting the measure of the given angle by 180
(the giving angle having a measure of 14°)
so missing angle = 180 - 14
180 - 14 = 166
Hence, the measure of the second angle 166°

What is the volume of this rectangular prism?
2/3
cm
5 cm
6 cm
Answer:
20cm^3
Step-by-step explanation:
The volume of a rectangular prism is just the 3 values multiplied by each other. So that would be 6x5x2/3 = 20cm^3

Chris is working on a stained-glass project and needs to form a triangle with sides of 8, 12, and 15 inches out of lead cane to enclose the glass. To the nearest tenth of a degree, what is the largest angle he needs to create using the lead caning?
Answer:
The largest angle needed is [tex]95.1^{o}[/tex].
Step-by-step explanation:
To determine the larges angle as required, let us apply the cosine rule.
[tex]c^{2}[/tex] = [tex]a^{2}[/tex] + [tex]b^{2}[/tex] - 2ab Cos C
Since in triangles, the longest side is opposite to the largest angle, then;
[tex]15^{2}[/tex] = [tex]8^{2}[/tex] + [tex]12^{2}[/tex] - 2(8 x 12) Cos θ
225 = 64 + 144 - 192 Cos θ
225 = 208 - 192 Cos θ
192 Cos θ = 208 -225
192 Cos θ = -17
Cos θ = [tex]\frac{-17}{192}[/tex]
Cos θ = -0.08854
θ = [tex]Cos^{-1}[/tex] -0.08854
= 95.07962
θ = [tex]95.1^{o}[/tex]
The largest angle needed is [tex]95.1^{o}[/tex].

Answer:
[tex]\text{log}_a(1.5^{-1})=\frac{-9}{5}[/tex]
Step-by-step explanation:
Given;
[tex]\text{log}_a(2)=\frac{1}{2}[/tex]
[tex]\text{log}_a(3)=5[/tex]
By using logarithmic properties,
[tex]\text{log}_a(2)-\text{log}_a(3)=\frac{1}{2}-5[/tex]
[tex]\text{log}_a(\frac{2}{3})=\frac{1}{2}-5[/tex]
[tex]\text{log}_a(\frac{1}{\frac{3}{2}})=\frac{1}{2}-5[/tex]
[tex]\text{log}_a(\frac{1}{1.5})=\frac{1}{2}-5[/tex]
[tex]\text{log}_a(1.5^{-1})=\frac{1-10}{5}[/tex]
[tex]\text{log}_a(1.5^{-1})=\frac{-9}{5}[/tex]

Naomi plotted the graph below to show the relationship between the temperature of her city and the number of popsicles she sold daily:
A scatter plot is shown with the title Naomis Popsicle Stand. The x axis is labeled High Temperature, and the y-axis is labeled Number of Popsicles Sold. Data points are located at 90 and 20, 85 and 17, 70 and 14, 75 and 20, 60 and 16, 50 and 14, 60 and 12, 40 and 10, 50 and 12, 80 and 8.
Part A: In your own words, describe the relationship between the temperature of the city and the number of popsicles sold. (2 points)
Part B: Describe how you can make the line of best fit. Write the approximate slope and y-intercept of the line of best fit. Show your work, including the points that you use to calculate the slope and y-intercept. (3 points)
Answer:
Answer:
A. The temperature of the city and the number of popsicles sold are positively correlated
B.
Slope: 0.1233
Y-Intercept: 6

From my assighment it is a increase.
Mark wants to paint a mural. He has 1 1/8 gallons of yellow paint, 1 1/9 gallons of green paint, and 7/8 gallons of blue paint. Mark plans to use 3/4 a gallon of each paint color. How many gallons of paint will he have left after painting the mural? Enter your answer as a simplified fraction.
Answer:
We have 31/36 gallons of paint left after painting the mural.
Step-by-step explanation:
"Mark wants to paint a mural. He has 1 1/8 gallons of yellow paint, 1 1/9 gallons of green paint, and 7/8 gallons of blue paint. Mark plans to use 3/4 a gallon of each paint color. How many gallons of paint will he have left after painting the mural? Enter your answer as a simplified fraction."
==================================================================
First change each number into a improper fraction:
1 1/8 = 9/8
1 1/9 = 10/9
7/8 = 7/8
=================================================================
"If Mark has 9/8 gallons of yellow paint, and he uses 3/4 gallons"
-We have to multiply 3/4 by 2/2 to make the denominators same.
3/4 × 2/2 = 6/8
Now subtract 6/8 from 9/8.
9/8 - 6/8 = 3/8
We will have 3/8 gallons of yellow paint.
==================================================================
"If Mark uses 10/9 gallons of green paint, and he uses 3/4 gallons"
- We have to multiply 10/9 by 4/4, and 3/4 by 9/9, to get a common denominator.
10/9 × 4/4 = 40/36
3/4 × 9/9 = 27/36
Now subtract 27/36 from 40/36
40/36 - 27/36 = 13/36
We will have 13/36 gallons of green paint.
==================================================================
"If Mark uses 7/8 gallons of blue paint, and he uses 3/4 gallons"
-We have to multiply 3/4 by 2/2 to get a common denominator.
3/4 × 2/2 = 6/8
Now subtract 6/8 from 7/8.
7/8 - 6/8 = 1/8
We will have 1/8 gallons of yellow paint.
==================================================================
Now, we will add the leftover amounts of paint to find the answer.
3/8 + 13/36 + 1/8
Add "like terms".
4/8 + 13/36
Simplify 4/8 into 1/2
1/2 + 13/ 36
Multiply 1/2 by 18/18 to get a common denominator.
1/2 × 18/18 = 18/36
Substitute 18/36 as 1/2 in the expression.
18/36 + 13/36 = 31/36
So, We have 31/36 gallons of paint left after painting the mural.
==================================================================

1000 chicken wings weighs 3000 g how many grams in one chicken wing weigh
Answer:
3 grams are in one chicken wing
Step-by-step explanation:
Set up an equation:
Variable x = grams per 1 chicken wing
1000/3000 = 1/x
Cross multiply
1000 × x = 3000 × 1
1000x = 3000
Divide both sides by 1000 to isolate the variable x
x = 3
Answer:
3
Step-by-step explanation:
3000/1000=3
At the mall, Jamie buys a pair of jeans for $34 and then a shirt for $12. The store is having a 25%
off sale. You will then have to pay 8% sales tax. What is the total amount you will pay?
Answer:
$37.26
Explanation:
firstly, we find the total original price: $34 + $12 = $46.
next, we can multiply this by 100% - 25% = 75% to find the discounted price:
$46 × 75%
= $46 ÷ 100 × 75
= $34.50
finally, add on the sales tax which is 100% + 8% = 108%:
$34.50 × 108%
= $34.50 ÷ 100 × 108
= $37.26

The degree of the polynomial function f(x) is 4.
The roots of the equation f(x)=0 are −2, −1, 1 and 3.
Which graph could be the graph of f(x)?
Answer:
Option A
Step-by-step explanation:
Degree of the polynomial function = 4
That means highest degree term of the given polynomial has power = 4
If the roots of a quadratic polynomial are a, b, c, d then the polynomial function will be,
f(x) = (x - a)(x - b)(x - c)(x - d)
It's given in the question that roots are x = -2, -1, 1 and 3
Therefore, polynomial function will be,
f(x) = (x + 2)(x + 1)(x - 1)(x - 3)
From the given options, graph A shows that the graph intersects the x-axis at x = -2, -1, 1 and 3
Therefore, Option A will be the answer.

104+76=180 and a circle is 360
- Thx for the points have a nice day! ^ω^
Answer:
A. 76
B. 256
Step-by-step explanation:
DF is a diameter so that means the right side of the
circle measure 180 degrees. Angle DGE measures 104, since that the central angle that means Arc DE measures 104 also.
Using arc addition, part of the right side measure 104 so that means the remaining arc must add up to 180.
[tex]104 + x = 180[/tex]
[tex]x = 76[/tex]
Arc EF measure 76.
2. A circle has 360 degrees in it. We are asked to find the measure of the circle expect the Arc ED.
Arc ED measures 104 so
[tex]360 - 104 = 256[/tex]

. The perimeter of a square is 8y – 12. The area of the square is 100 square units. What is the value of y?
Answer:
y = 6.5 units
Step-by-step explanation:
Let L be the length of sides of the square.
Given the following data;
Perimeter of square = 8y - 12
Area of square = 100 square units
To find the value of y;
Area of a square = L²
Substituting into the formula, we have;
100 = L²
L = √100
L = 10 units
Mathematically, the perimeter of a square is given by the formula;
Perimeter of a square = 4L
Substituting into the formula, we have;
8y - 12 = 4*10
8y - 12 = 40
8y = 40 + 12
8y = 52
y = 52/8
y = 6.5 units
