67.5 - number of hour Gibert works and the
60 - total amount of money he earns.

Answer:
You can put the dollars on the y axis and the hours on the x axis. Whenever the hours increase by 1, move over 1 on the x axis and 7.50 up on the y axis.
The first point should be (1, $7.50).
↑ ↑
hours, money earned
The second point then will be (2, $15.00), the third will be (3, $22.50), and so on.

715,000 ___ 7.15 × 10 5 a. > b. = c. <
Answer:
b. =
Step-by-step explanation:
First, we have to figure out 7.15x10^5.
10^5=100,000
100,000x7.15=715,000
So, 715,000 is equal to 7.15x10^5.
715,000=7.15x10^5
Hope this helped...have a nice day c:
Answer:
b)=
Step-by-step explanation:
7.15* 10^5=
10^5= 100000
(1 with 5 zeros at the end)
7.15*100000= 715,000
715,000 compared 715,000:

Bananas cost $0.47 per pound and Amanda purchased x pounds. She spent a total of $1.41. Which equation expresses the amount Amanda spent on bananas?
0.47 + x = 1.41
0.47 - x = 1.41
0.47x = 1.41
1.41x = 0.47
[tex]0.47x = 1.41[/tex]
[tex]x = \frac{1.41}{0.47} = 3[/tex]

1. G (7, 3), H (-1, 1), and I (-3, 4) are the coordinates of a triangle's vertices. If the triangle is reflected over the x-axis, what are the coordinates of the image?
G '(7, -3), H '(-1, -1), I '(-3, -4)
G '(7, 3), H '(-1, -1), I '(-3, 4)
G '(7, 3), H '(-1, 1), I '(-3, -4)
G '(7, -3), H '(1, -1), I '(-3, -4)
2. A (2, 5), B (6, -3), and C (8, 0) are the coordinates of a triangle's vertices. If the triangle is reflected over the y-axis, what are the coordinates of the image?
A '(-2, -5), B '(-6, -3), C '(8, 0)
A '(-2, 5), B '(-6, 3), C '(-8, 0)
A '(-2, 5), B '(-6, -3), C '(-8, 0)
A '(2, -5), B '(6, 3), C '(8, 0)
Answer:
Under a reflection in the x- axis
a point (x, y ) → (x, - y ), hence
G(- 2, 1) → G'(- 2, - 1)
H(- 7, 4) → H'(- 7, - 4)
Why aren’t there infinitely many semi-regular tessellations?

Step-by-step explanation: Its not A cuz 7 is a decimal, its not B because of there being 2 p's and same for D
Answer:
D. p + 0.07p
Step-by-step explanation:
Answer choice D is correct because if we were to plug in a variable (e.g. 1 and 2), we would get the same amount when using 1.07p. All the other answer choices either work for only one value or don't work at all.
For example,
1 + 0.07(1) = 1.07(1).1 + 0.07 = 1.07
1.07 = 1.07
2 + 0.07(2) = 1.07(2)2 + 0.14 = 2.14
2.14 = 2.14

The length of a cell phone is 1.81.8 inches and the width is 4.84.8 inches. The company making the cell phone wants to make a new version whose length will be 1.621.62 inches. Assuming the side lengths in the new phone are proportional to the old phone, what will be the width of the new phone?
Answer: 4.32432 inches
Step-by-step explanation:
This is a simple ratio problem:
we are given the old dimensions:
L x W = 1.818 x 4.848
new = 1.62162 x ?
? = (1.62162 x 4.848)/1.818 = 4.32432
The width of the new phone should be 4.32432 inches

\text{Time (hours)}Time (hours) \text{Earnings (dollars)}Earnings (dollars) 4 \$70.8099 \$159.30 28 \$495.60 How long does it take him to make \$132.75
Answer:
7.5 hrs.
Step-by-step explanation:
First we need to find how much Magan earns per hour using the slope-intercept form: y = mx + b
Slope (m) = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
We will be using: (4, 70.80) and (9, 159.30) to find the slope of this table..
[tex]m=\frac{y_2-y_1}{x_2-x_1} \\\\m=\frac{159.30-70.80}{9-4} \\\\m=\frac{88.50}{5} \\\\m=17.7[/tex]
y = mx + b
y = 17.7x + b
I will be using (4, 70.80) to find the value of b
(4, 70.80)
y = 17.7x + b
70.80 = 17.7(4) + b
70.80 = 70.80 + b
-70.80 -70.80
0 = b
y = 17.7x + b ==> y = 17.7x + 0 = OR y = 17.7x (since the value of b is 0)
The question wants us to find out how long it took Magan to make $132.75
y = 17.7x
132.75 = 17.7x
/17.7 /17.7
7.5 = x
This means that it took him 7.5 (seven and a half) hours to make $132.72

Determine the length of the unknown side of the right triangle. If it is not an exact answer, what integer is it closest to? (Don't forget to include units!)
Answer:
=> The third side of the triangle is √53 mm
Step-by-step explanation:
We know that this is a right angled triangle ,
so , by using Pythagoras theorem we can find out the third side of the triangle ,
=> P²+B²= H²
=> 7²+2² = H²
=> 49+4 = H²
=> 53 = H²
=> √53 = H
The third side of the triangle is √53mm

Given:
∠A = 50°In the diagram given, we can tell that:
∠A and ∠B are a linear pair.∠B and ∠C are a linear pair.This means that:
∠A + ∠B = 180°∠B + ∠C = 180°Step-1: Find ∠B.
∠A + ∠B = 180°=> 50 + ∠B = 180°=> ∠B = 180 - 50=> ∠B = 130°Step-2: Find ∠C.
∠A = ∠C (Vertically opposite angles=> ∠C = 50°∠A+∠B = 180° [Linear pair]
50+ ∠B = 180°
∠B = 180-50
∠B = 130°

Construct an isosceles triangle with one 70* angle and two 4 inch sides. Is this a unique triangle? Explain why or why not.
The isosceles triangle has 2 equal sides of 4 inches and a vertex angle measure of 70 degrees, and it is a unique triangle
How to determine if the triangle is unique?The given parameters are:
Triangle type = Isosceles triangle
Side length = 4 inches
Angle measure = 70 degrees
Since the triangle is an isosceles triangle, then the equal angles would be:
Ф = 180 - 2 * 70
Ф = 40
The length (L) of the third side is:
L/2 = 7 * cos(40)
Multiply both sides by 2
L = 14 * cos(40)
L = 10.7
So, the angles in the triangle are 70 and 40 degrees; while the side lengths are 4 and 10.7 inches
