Answer:
15/56
Step-by-step explanation:
42*4n=45
4n=45/42
4n=15/14
n=(15/14)/4
n=(15/14)(1/4)
n=15/56
Answer:
Step-by-step explanation:
42 ⋅ 4n = 45
4n= 45/42 = 15/14
n = 15/14/4 = 15/56
What is the surface area of this right circular cone? (plsss help lol 20 points)
Answer:

Combine the like terms -6m + 4m. Simplify your answer
Answer:
-2m
Step-by-step explanation:
-6m + 4m
Combine like terms by performing the operation between the coefficients. In this case, one must add the different coefficients, yet since one of the coefficients is negative, then adding the two coefficients is the same as subtracting the two terms.
-6m + 4m
= -2m

Answer:
a) $2.40
b) $16.80
c) y = -2.40x +16.80
Step-by-step explanation:
a. Dylan's daily spending is the opposite of the slope of the line on the graph. That slope can be found using the slope formula:
m = (y2 -y1)/(x2 -x1)
m = (4.8 -12)/(5 -2) = -7.2/3 = -2.4
Dylan spends $2.40 at lunch every day.
__
b. The y-intercept can be found from the formula ...
b = y1 -m(x1)
b = 12 -(-2.40)(2) = 16.80
Dylan's dad gives him $16.80 at the beginning of each week.
__
c. The slope-intercept equation is ...
y = mx + b
y = -2.40x +16.80

Answer:
Angle ADC = 80 degrees
Step-by-step explanation:
Here, we want to find the measure of angle ADC
mathematically, sum of angles at a point is 360
Thus;
x + 3x + x + 10 = 360
5x + 10 = 360
5x = 360-10
5x = 350
x = 350/5
x = 70
From the diagram;
angle ADC is (x + 10)
so we have; (70 + 10) = 80 degrees
Bob bought a broken motor scooter, repaired it, and sold the scooter for $130. That was $50 less than 1.5 times what he paid for it.
Answer: $120
Step-by-step explanation:
Assume the original price is x.
He sold the scooter for $130 and this was $50 less than 1.5 times what he paid for it.
Relevant formula is therefore:
1.5x - 50 = 130
1.5x = 130 + 50
x = 180/1.5
x = $120

Anil scored 30 runs in the first innings of a test match. His score changed by +30 runs in the second innings. What was his score in the second innings?
Answer:
60 runs
Step-by-step explanation:
Given that:
Score in first innings = 30 runs
Change in score during second inning = + 30
The score in the second inning will be :
Score in first inning + change in score during second inning
30 + (+30)
30 + 30
= 60 runs
Elizabeth invests $7567 in a savings account with a fixed annual interest rate of 5% compounded quarterly. What will the account balance be after 7 years?
Answer:
FV= $10,714.81
Step-by-step explanation:
Giving the following information:
Initial investment= $7,567
Number of periods= 7*4 = 28 quarters
Interest rate= 0.05/4= 0.0125
To calculate the future value, we need to use the following formula:

In ΔQRS, the measure of ∠S=90°, RS = 2.2 feet, and QR = 4.5 feet. Find the measure of ∠Q to the nearest tenth of a degree.
Answer:
[tex]Q = 29.3^\circ[/tex]
Step-by-step explanation:
Given
[tex]\angle S = 90[/tex]
[tex]RS = 2.2ft[/tex]
[tex]QR = 4.5ft[/tex]
See attachment for ΔQRS
To calculate <Q, we make use of:
[tex]sin\ Q = \frac{Opposite}{Hypotenuse}[/tex]
Where
[tex]Opposite = RS[/tex]
[tex]Hypotenuse = QR[/tex]
[tex]sin\ Q = \frac{RS}{QR}[/tex]
[tex]sin\ Q = \frac{2.2}{4.5}[/tex]
[tex]sin\ Q = 0.4889[/tex]
Take arc sin of both side
[tex]Q = sin^{-1}(0.4889)[/tex]
[tex]Q = 29.3^\circ[/tex]
At a birthday party, Vivian counts 15 vanilla ice cream cups and 25 chocolate ice cream cups. Which properties can be used to determine the percent, p, of the ice cream that is chocolate?
Answer:
62.5 %
Step-by-step explanation:
The percentage, p of the ice cream that is chocolate is p = total number of chocolate ice cream cups/total number of ice cream cups × 100%
Given that there are 25 chocolate ice cream cups and 15 vanilla ice cream cups, total number of ice cream cups = 25 + 15 = 40
So, p = total number of chocolate ice cream cups/total number of ice cream cups × 100%
p = 25/40 × 100%
p = 25/4 × 10 %
p = 6.25 × 10 %
p = 62.5 %
A number q divided by 5 is 8

For what values of t can 2x^2+tx+10 be written as the product of two binomials?
The value of t for which the given expression 2x²+tx+10 will be a product of two binomial is 9.
What is binomial?A binomial expression is an expression that has two terms.
In order to get the value of t for which the given expression 2x²+tx+10 will be a product of two binomial. We need to find a number(A) that is when broken into two other numbers(B and C), the sum of these numbers(B and C) is the number itself(A). Also, the product of the two numbers is equal to the product of the rest two terms of the expression(2 and 10).
Therefore, the number that fulfills this condition is 9. Let's check by substituting the value of t as 9.
[tex]2x^2+tx+10\\\\= 2x^2+9x+10 \\\\= 2x^2+5x+4x+10\\\\ = x(2x + 5)+2(2x+5)\\\\= (x+2)(2x+5)[/tex]
Hence, the value of t for which the given expression 2x²+tx+10 will be a product of two binomial is 9.

At Maddison high school each student studies one foreign language is 3/5 take Spanish and one-fourth of the remaining take german what percent takes frnechan how
Answer:
Step-by-step explanation:
3/5 = 0.6
1 - 0.6 = 0.4 students left
Multiply the amount of students remaining by the fractional amount that take German
0.4 x 1/4 = 0.1
1 - 0.6 - 0.1 = 0.3
0.3 x 100 = 30%
Therefore 30% of students take French
