Peter earns $ 12.40 each week for completing his chores. Ria earns 1.2 times as money per week as Peter. How much does peter earn each week.? Show your work.
Answer:
Ria earns 14.88 dollars each week
Step-by-step explanation:
Amount earned by peter every week = $12.40
If Ria earns 1.2 times as money per week as Peter, then;
Amount Ria earns = 1.2 * 12.40
Amount Ria earns = 14.88
Hence Ria earns 14.88 dollars each week

Answer:
The perimeter of the pentagon is;
29 units
Step-by-step explanation:
Let A, B, C, D, and E represent the vertices of the pentagon
The "x" and "y" coordinates of the vertices of the pentagon are given as follows;
A(-6, 2), B(-2, -2), C(5, -2), D(5, 2), E(-2, 5)
The length of the sides between each pair of coordinates can be found using the following formula;
[tex]l = \sqrt{\left (y_{2}-y_{1} \right )^{2}+\left (x_{2}-x_{1} \right )^{2}}[/tex]
Therefore, we have;
Length of segment AB = √((-2 - (2))² + (-2 - (-6))²) = 4·√2
Length of segment BC = √((-2 - (-2))² + (5 - (-2))²) = 7
Length of segment CD = √((5 - 5)² + (2 - (-2))²) = 4
Length of segment DE = √((5 - 2)² + (-2 - 5)²) = √58
Length of segment EA = √((5 - (2))² + (-2 - (-6))²) = 5
The length of the perimeter of the pentagon = 5+√58 + 4 + 7 + 4·√2 ≈ 29.2726273554 ≈ 29
The length of the perimeter of the pentagon ≈ 29.

You have 8 cups of flour. It takes 1 cup of flour to make 24 cookies. The function C(f) = 24f represents the number of cookies, C, that can be made with f cups of flour. Which set of ordered pairs represent points on the graph of C(f) = 24f?
Answer:
c(0) = 24*0 = 0
c(8) = 24*8 = 192
Your range is [0,192]
Step-by-step explanation:
Answer:
You have 8 cups of flour it takes 1 cup of flour to make 24 cookies the function c(f)=24f
c represents the number of cookies
f represents the cups of flour
You have 8 cups of flour, we can use only 0 to 8 cups of flour.
so domain f is 0 to 8 cups [0,8]
Now we find the range
1 cup of flour to make 24 cookies
So 8 cups of flour = 24* 8 = 192 cookies
using 8 cups you can make 192 cookies
So number of cookies is from 0 to 192
Range is [0,192

B.

C.
The graph has an x-interceptat (1,0).
D.
The graph has the y-axis as a line of symmetry.
E.
The graph has zeros at x = -5 and x = -1.
F.
The graph represents the function f(x) = -x2 - 6x - 5.
Answer:
E
Step-by-step explanation:
The statements that are not true are:
The graph has a y-intercept at (0,5) is not true.
The graph has a relative maximum point (-3,4) is not true,
The graph has zeros at x = -5 and x = -1 is not true.
Options, A, B, and E are the correct answer.
What is a function?A function has an input and an output.
A function can be one-to-one or onto one.
It simply indicated the relationships between the input and the output.
Example:
f(x) = 2x + 1
f(1) = 2 + 1 = 3
f(2) = 2 x 2 + 1 = 4 + 1 = 5
The outputs of the functions are 3 and 5
The inputs of the function are 1 and 2.
We have,
- The y-intercept can be found by setting x=0, which gives f(0)=-5.
So the y-intercept is (0,-5).
- To find the relative maximum,
We need to find the vertex of the parabola.
The x-coordinate of the vertex is given by -b/2a, where a=-1 and b=-6.
So, x=3 is the x-coordinate of the vertex.
To find the y-coordinate, we plug in x=3 into the function:
f(3) = -(3²) - 6 (3) - 5 = -32.
So the vertex is (3,-32), which is a relative minimum, not a maximum.
- To find the x-intercepts,
We set y =0 and solve for x.
-x² - 6x - 5 = 0.
Factoring or using the quadratic formula,
We get x = -5 and x = -1.
- The y-axis is a line of symmetry for any parabola of form f(x)=ax²,
f(-x) = a (-x)² = ax² = f(x).
- To find the zeros,
We set f(x) = 0 and solve for x.
-x² - 6x - 5 = 0.
Factoring or using the quadratic formula,
We get x = -5 and x = -1.
So the graph has zeros at x = -5 and x = -1, not x = -2 and x = 3.
- The graph represents the function f(x) = -x2 - 6x - 5.
The graph is true.
Thus,
The graph has a y-intercept at (0,5) is not true.
The graph has a relative maximum point (-3,4) is not true,
The graph has zeros at x = -5 and x = -1 is not true.

Answer:
First you have to plot Bart's Garage's fee. Bart's equation is y = 30x + 20, so you would need to plot the points (0, 20) and (1, 50).
Lisa's base fee is the same, so her equation would have a + 20 at the end of it, but her hourly fee is higher. Therefore her hourly fee would be higher than 30. Her equation could be anything above 30, y = 50x +20 would work. The points for that graph are (0, 20) and (1, 70).

Yolanda makes wooden boxes for a crafts fair. She makes 300 boxes like this one shown, and she wants to paint all the outside faces. Find the surface area of one box.
Answer:
240
Step-by-step explanation:
that is it
The surface area of one box is 62 square inches.
What is surface area of a cuboid?The surface area of a cuboid is the total space occupied by it. A cuboid is a six-faced three-dimensional shape in which each face is in the shape of a rectangle.
Given that, Yolanda makes wooden boxes for a crafts fair.
The dimensions of box are length= 5 inches, breadth = 3 inches and height = 2 inches.
We know that, the formula to find the toral surface area of cuboid is 2(lb+bh+hl)
Now, surface area = 2(5×3+3×2+2×5)
= 2(15+6+10)
= 2(31
= 62 square inches.
Therefore, the surface area of one box is 62 square inches.

megan is trying to find the length of the segment using the Pythagorean Theorem
Part A : megan made one mistake in her work , which caused her to get the wrong answer what did she do wrong?
Part B : Calculate the correct length of the segment
Answer:
10
Step-by-step explanation:
To obtain the length of the segment :
a² + b² = c²
a = 8 ; b = 6
8² + 6² = c²
64 + 36 = c²
100 = c²
Square root of both sides :
Sqrt(100) = sqrt(c²)
10 = c
Mistake in the solution is that 6² = 36 and not 12
