hope that helps
Answer:
30 cm
Step-by-step explanation:
we know that the area of a square is axa (a side)
that is a^2
a^2 = 900
prime factorization of 900 = 2x3x5
=30 cm
( verification ) axa = 30x30 ='900
perimeter = 4x side
side=30
=30x4
=120 cm
therefore ans done

Which equation represents exponential growth?
O A) y= 2x
O B) y = 3(5)
OC) y = 4x?
OD) y = 2(0.5)
Answer:
C) y = 4x?
Step-by-step explanation:
Exponential growth is a process that increases quantity over time. It occurs when the instantaneous rate of change of a quantity with respect to time is proportional to the quantity itself.
There are two types of exponential functions: exponential growth and exponential decay. In the function f (x) = bx when b > 1, the function represents exponential growth. In the function f (x) = bx when 0 < b < 1, the function represents exponential decay

Which ordered pair represents the reflection of the point (-4, 6) across both axes? O (4,6) O (4, -6) 0 (-4,6) O (-4,-6)
Reflecting across the Y axis, the y value stays the same and the X value become opposite:
(-4,6) would become (4,6)
Now reflecting across the X axis the x value remains the same and the Y value becomes the opposite:
(4.6) would become (4,-6)
Answer: (4,-6)

C(x) = (12,000x - 0.02x^3) - (3000x - 0.002x^3)
Write a simplified expression for C(x).
A. C(x) = -0.022x^3 + 9000x
B. C(x) = -0.018x^3 + 9000x
C. C(x) = -0.022x^3 + 15,000x
Answer:
B
Step-by-step explanation:
C(x) = (12,000x - 0.02x^3) - (3000x - 0.002x^3)
C(x) = 12,000x - 0.02x^3 - 3000)x + 0.002x^3
C(x) = (12,000 - 3,000)x + (-0.02 - 0.002)x^3
= 9000x - 0.018x^3

Answer:
30
Step-by-step explanation:
To work this out we do:
6÷20%
6÷0.2
30
This makes sense since 20% of 30 will be 10%(3) ×2 = 6
Answer:
30
Step-by-step explanation:
Equation ---> 6 = 20%
to get to 100% you multiply 20% by 5.
20% x 5 = 100%
So you do the same to the other side of that equation
6 x 5 = 30
6 is 20% of 30

Eve plays basketball. She makes 5 free throws for every 3 free throws that she misses. If she missed 36 free throws at her last practice, how many free throws did she make?
Answer:
60
Step-by-step explanation:
We can write a proportion to solve
5 made x made
------------ = -----------
3 missed 36 missed
Using cross products
5 * 36 = 3x
Divide each side by 3
5 * 36/3 = 3x/3
50 = x
She made 60
Why does a fraction with lesser denominator have larger pieces than the fraction with a greater denominator
Answer:
Step-by-step explanation:
The bigger the denominator the smaller the fraction.
For example if you have 1/9 and 1/5.
The fraction 1/5 has a greater denominator and is greater than 1/9, because it is split into less parts.

Solve the system of linear equations by substitution.
x + 4y = 21
y = −x + 12
the solution to the system is ( , ) answer is an ordered pair
=========================================================
Explanation:
We can replace y in the first equation with -x+12 due to the second equation.
x+4y = 21
x+4( y ) = 21
x + 4(-x+12) = 21
x-4x+48 = 21
-3x = 21-48
-3x = -27
x = -27/(-3)
x = 9
which leads to,
y = -x+12
y = -9+12
y = 3
Therefore, the solution as an ordered pair is (x,y) = (9, 3)
---------------
Check:
x+4y = 21
9+4(3) = 21
9+12 = 21
21 = 21 .... the first equation works
and,
y = -x+12
3 = -9+12
3 = 3 ... so does the second equation
Both equations are true for those x and y values. The answer is fully confirmed.
