B and C are out because those numbers are too high. A is out for 2 reasons. 1) 5x5 is 25, not 5x3 and 2) a negative times a positive is negative.
So the answer is D

To simplify the expression (-5)^3, we need to evaluate the exponent, which means multiplying the base (-5) by itself three times. The correct option is B. -125.
(-5)^3 = (-5) * (-5) * (-5)
Multiplying the negative numbers gives:
(-5) * (-5) * (-5) = 25 * (-5) = -125
Therefore, the simplified expression is -125.
So, when we simplify the expression (-5)^3.The correct option is B. -125.

Answer:
1 ÷ 2 pounds
Step-by-step explanation:
The computation is shown below:
As we know that
1 pound = 0.454 Kg
Peanut starting weight = 3 ÷ 4 of a pound.
In the case when the bag is 2/3 full, so the weight is
= 2 ÷ 3 × 3 ÷ 4
= 1 ÷ 2 pounds

The circumference of a circle is m. What is the area , in square meters ? Express your answer in terms of pi
Answer:
area = m²/2π
Step-by-step explanation:
∵ circumference of circle = 2πr = m
∴ r = m/2π
∵ area of circle = πr²
∴ area of circle = (m/2π)² × π = m²/2π² × π = m²/2π

What is BC? Plz help
Answer and Step-by-step explanation:
To find the length of BC, we will be using the trigonometric function Sine.
The Sine trig function is as follows:
sin(θ) = [tex]\frac{Opposite Side}{Hypotenuse}[/tex]
Plug in the values and solve for the Hypotenuse (BC)
[tex]sin(45) = \frac{8}{x}[/tex]
Multiply x to both sides, then divide both sides by sin(45).
x = [tex]\frac{8}{sin(45)}[/tex]
Input into a calculator and solve.
The length of BC is [tex]8\sqrt{2}[/tex], or 11.3137.

3. Hessa is building a scale model of a park. She uses a scale of 12 cm to represent 1.5 m. a) The actual length of the bridge is 20 m. What is the length of the model bridge? b) In the model, the height of the climbing frame is 10 cm. What is the actual height of the frame?
Answer:
160cm
80cm
Step-by-step explanation:
If 12cm = 1.5m
convert cm to meter
1 meter = 12/1.5 = 8cm
20m = 20m x 8 cm = 160 cm
10cm = 10 x 8 = 80cm

Slope intercept form is y = mx + b
m is slope
b is y intercept
y = -4/5x + -9
I only know that first one sry
Step-by-step explanation:
Answer:
yes.
Step-by-step explanation:
slope intercept form is y=mx+b
b is the y intercept, m is the slope, and x is x.
for
1. it would be
y= -4/5x -9
2. You take the points and do (y2-y1) DIVIDED BY (x2-x1)
it would look like:
(5- -3) / (3-0) = (8/3)
Then plug in one of the sets of numbers for x and y, to get y intercept.
5=8/3(3)+b
b=-3
So.. slope intercept would be y=8/3x -3
Over what interval is the function in this graph increasing
Answer:

Has the marrying age of a man changed over the years? The United States Bureau of the Census takes a formal count of everyone in the U.S. every 10 years and has provided the following data that gives the median age of an American man at the time of his first marriage.
What does it mean in this situation if the average rate of change is negative?
a.
It means that the median age of a man at the time of his first marriage is increasing.
b.
It means that the median age of a man at the time of his first marriage is decreasing.
c.
It means that the median age of a man at the time of his first marriage has a constant rate of change.
d.
There is no way to determine the average rate of change in this situation.
The Answer is D
Answer:
If the average rate of change in the data is negative, based on the variables analyzed;
b. It means that the median age of a man at the time of his first marriage is decreasing
Step-by-step explanation:
The given data is presented as follows;
Year; [tex]{}[/tex] 1910, 1920, 1930, 1940, 1950, 960, 1970, 1980, 1990, 2000
Median Age; [tex]{}[/tex] 25.1, 24.6, 24.3, 24.3, 22.8, 22.8, 23.2, 24.7, 26.1, 26.8
The date points are plotted on a graph using Microsoft Excel
[tex]The \ average \ rate \ of \ change = \dfrac{The \ change \ in \ the \ median \ age}{The \ corresponding \ change \ in \ years \ (always \ +ve)}[/tex]The corresponding change in years, Δx, is positive because, we have;
Δx = x₂ - x₁ = Higher year - Previous year
Therefore, for a negative average rate of change, we have;
[tex]The \ average \ rate \ of \ change = -ve = \dfrac{The \ change \ in \ the \ median \ age}{+ve}[/tex]
∴ The change in the median age, Δy = +ve × (-ve) = -ve (negative)
Δy = -ve
∴ Δy = Median age for higher year - Median age for previous year = -ve
Median age for higher year = -(y) + Median age for previous year
Where 'y' is positive
∴ Median age for subsequent year < Median age for previous year
Therefore, if the average rate of change is negative, the median age of a man's first marriage is decreasing

Which pair of expressions are equivalent? 2y minus four and 2y minus four plus 9, 14x minus seven and 7x minus fourteen, 9y plus 3 plus two and 3(y plus one) plus two, x plus y and x minus y plus 2y, x plus 2y and x minus y
Answer:
D. x plus y and x minus y plus 2y
x + y
x + y
Step-by-step explanation:
2y minus four and 2y minus four plus 9
2y - 4
2y - 4 + 9
14x minus seven and 7x minus fourteen
14x - 7
7x - 14
9y plus 3 plus two and 3(y plus one) plus two
9y + 3 + 2
3(y + 1) + 2 = 3y + 3 + 2
x plus y and x minus y plus 2y,
x + y
x - y + 2y = x + y
x + y
x + y
x plus 2y and x minus y
x + 2y
x - y

A number when divided by 5 gives 0 as remainder, that number when divided by 7 gives 0 as remainder also. What will be the remainder when that number is divided by 35?
Answer:
zero
Step-by-step explanation:
The computation of the remainder when the number would be divided by 35
Let the number be x
So if x is divided by 5 gives the remainder 0
x = 0
And, if x is divided by 7 gives the remainder 0
x = 0
So if x is divided by 35 so the remainder is also zero
