Answer:
726 children
242 adults
Step-by-step explanation:
a + c = 968
6c + 11a = 7018
Use Substitution: c = 968-a
6(968-a) + 11a = 7018
5808 - 6a + 11a = 7018
5a = 1210
a = 242
c = 968 - 242 = 726
Kayla studied data collected on the school basketball team for one season. She noticed that a player on the team had 13 successful free throws out of a total of 20 attempted free throws. What percent is that?
If she is setting up a proportion to find the percent, the value of m would be any variable and the value of n would be 100. When she solves the problem, m=65%.
13/20 is part out of whole. The rest of the proportion will be "percent out of 100"; since we don't initially know the percent, we use a variable. Thus we have
13/20 = m/100
Cross multiply:
20*x = 13*100
20x = 1300
Divide both sides by 20:
20x/20 = 1300/20
x = 65

What are the zeros of f(x)=x^3+2x^2-7x+4? Which statement is true regarding the behavior of the graph of f at each zero
Answer: (-4,0) , (1,0)
Step-by-step explanation:
I used this website called Desmos it could help with your questions like this.
Answer:
Step-by-step explanation:
f(x)=x³+2x²-7x+4
at x=1
f(1)=1³+2(1)²-7(1)+4=1+2-7+4=0
so x=1 is one zero.
1) 1 2 -7 4
| 1 3 -4
___________
1 3 -4 |0
x²+3x-4=0
x²+4x-x-4=0
x(x+4)-1(x+4)=0
(x+4)(x-1)=0
x=-4,1
zeros are -4,1,1
coefficient of leading term is +
so it starts from bottom on the left at ends up on the right.
There is a cusp at x=1
or it decreases on left of 1 and and increases on the right.
at x=-4 ,it increases.

hat is the surface area of a cylinder that has a volume if 785.4in3 and a radius of 5 in?
A 471.2in2
B 10in2
C 150in2
D 4712.3in2
Answer:
A. 471.2 in²Step-by-step explanation:
Cylinder volume:
V = πr²hCylinder surface area:
A = 2πr(r + h)Find h from the first equation:
h = V/(πr²) = 785.4/(3.14*5²) = 10 inFind surface area:
A = 2π(5)(5 + 10) = 471.23 in²Correct choice is A
Answer:
volume of cylinder=πr²h
785.4=22/7×5²×h
h=785.4×7/(22×25)=9.99=10in
Step-by-step explanation:
surface area of cylinder =2πr(r+h)=2π×5(5+10)=
471.238898038in²
A 471.2in2 is your answer.
What is the angle of F?
R 134 degrees
L 68 degrees
Answer:
angleF=66
Step-by-step explanation:
F+L=R

slope point -
through:(3,-1) and (-1,-4)
Answer:
m = 3/4 or 0.75Step-by-step explanation:
Use slope formula:
m = (y₂ - y₁)/(x₂ - x₁)Substitute values of coordinates:
m = (-4 - (-1))/(-1 - 3) = -3/-4 = 3/4 or 0.75Slope
m=(-4+1)/(-1-3)m=-3/-4m=3/4Need help plz?????????!!!!!!
Answer:
93°
Step-by-step explanation:
By exterior angle theorem:
(4x + 9)° = 2x° + (3x - 12)°
(4x + 9)° = (2x + 3x - 12)°
(4x + 9)° = (5x - 12)°
4x + 9 = 5x - 12
4x - 5x = - 12 - 9
-x = - 21
x = 21
Measure of exterior angle
= (4x + 9)°
= (4*21 + 9)°
= (84 + 9)°
= 93°

Four more than the product of 2 and a
Four more than the product of 2 and a:
4+2a
Answer:
2a + 4
Step-by-step explanation:
The key word, "product," means you're multiplying, and since it says the "product of 2 and a," you're multiplying 2 and a. To simplify that, you can write 2a (which is equal to 2 · a).
Since it says four more (key word is more), you need to add four to 2a. Since if you have "less than" or "more than", the product will be before the number we're adding, leaving you with 2a + 4.
