Answer:
The answer is 40.
Step-by-step explanation:
If you do 40 x 5 the answer you get is 200. Which from there you can do 40 x 7 and get 280 which 280 - 200 is 80. Thus meaning the number would be 40. Hope this helps!

The local skating rink pays Mary a fixed rate per pupil plus a base amount to work as a skating instructor. She earns $90 for instructing 15 students on Monday afternoon. Last Friday, she earned $62 for working with 8 students. Lisa is also a skating instructor. She receives half the base amount that Mary does, but she is paid twice as much per student. Who would earn more money instructing a class of 20 students?
Answer:
lisa would earn more money
Step-by-step explanation:
let say mary base price = x
mary per student price = y
x+15y = 90
x+8y = 62
7y = 28
y =4
x = 30
mary will earn for 20 students = 30 + 20*4 = 110
lisa base money = 30/2= 15
lisa per student = 4*2=8
lisa earning for 20 students
= 15 + 20*8 = 175
lisa will earn more money

2.) Combine like terms and simplify the expression: 2x +
5y+ 7x
Your answer
Answer:
9x + 5y
Step-by-step explanation:
Here, in 2x + 5y+ 7x, the 'like terms' are 2x and 7x, and the sum of these terms is 9x. Thus, 2x + 5y+ 7x becomes 9x + 5y.

The measure of the minor arc in the circle shown below is
degrees.
210°
Part B
If the radius of the circle is 12 inches, the area of the sector contained by the minor arc and two radii is:
(b)
357 in.
B 557 in.
2
607 in.2
D757 in.
Answer:
[tex]A=60\pi\ in^2[/tex]
Step-by-step explanation:
The angle made by the major arc = 210°
The sum of the measure of major arc and the minor arc is equal to 360°.
Minor arc = 360° - 210° = 150°
The radius of the circle, r = 12 inches
The area of the sector is given by :
[tex]A=\dfrac{\theta}{360}\times \pi r^2\\\\=\dfrac{150}{360}\times \pi (12)^2\\\\=60\pi\ in^2[/tex]
So, the correct option is (c) i.e. [tex]60\pi\ in^2[/tex].
You have just gotten your first job. You have decided you want to take your parents out for dinner to celebrate and you have anticipated it will cost approximately $120 for the three of you to go out for dinner. At your job, you make an hourly wage of $11. How many hours would you need to work to pay for the dinner? What if you wanted to add a 15% tip? Could your strategy also allow you to find out how much money you made for any number of hours?
Answer:
I will have to work 11 hours to take my parents to a $ 120 cost dinner, and I will have $ 1 left in return.
If I wanted to tip 15%, I would have to work 13 hours and have $ 5 left over.
In turn, to determine the money generated from an indeterminate number of hours worked, the applicable formula would be 11X = Y, where Y is the money generated and X is the number of hours worked.
Step-by-step explanation:
Since I have just gotten my first job, and I have decided I want to take my parents out for dinner to celebrate and I have anticipated it will cost approximately $ 120 for the three of us to go out for dinner, and at my job, I make an hourly wage of $ 11, to determine how many hours would I need to work to pay for the dinner, and what if I wanted to add a 15% tip, and determine if my strategy could also allow me to find out how much money and or made for any number of hours, the following calculations must be performed:
120/11 = X
10.9 = X
11 x 11 = 121
Therefore, I will have to work 11 hours to take my parents to a $ 120 cost dinner, and I will have $ 1 left in return.
(120 x 1.15) / 11 = X
138/11 = X
12.54 = X
11 x 13 = 143
Therefore, if I wanted to tip 15%, I would have to work 13 hours and have $ 5 left over.
In turn, to determine the money generated from an indeterminate number of hours worked, the applicable formula would be 11X = Y, where Y is the money generated and X is the number of hours worked.

The rectangle and the square have the same area. Write down an
equation in terms of x and solve it.
Answer:
x² = (x-2) (x+3)
and
x = 6
Step-by-step explanation:
x² = (x-2) (x +3)
x² = x² + 3x - 2x - 6
x² = x² + x - 6
moving x² and -6 from LHS to RHS
x² - x² + 6= x
6 = x
x = 6

A rectangular prism has the following dimensions.
length: 18 inches
width: 1 foot
height: 14 inches
If all the dimensions of this prism are tripled, what will be the surface area of the new figure?
7,632 in. 2
11,448 in. 2
3,816 in. 2
27,216 in. 2
Answer: 11,448
Step-by-step explanation: I’m not sure if this is correct but I saw this answer a few times on another website similar to Brainly, and I thought it could help you all, if it’s correct.
The surface area of new rectangular prism is 11448 square inches.
What is a rectangular prism?A rectangular prism can be defined as a 3-dimensional solid shape which has six faces that are rectangles. It has 8 vertices, 6 faces, and 12 edges in which all the pairs of opposite faces are congruent.
For the given situation,
Length of the rectangular prism = 18 inches
Width of the rectangular prism = 1 foot = 12 inches
Height of the rectangular prism = 14 inches
All the dimensions are tripled, so multiply all the dimensions by 3.
Length, l = [tex](18)(3)[/tex]
⇒ [tex]l=54[/tex]
Width, w = [tex](12)(3)[/tex]
⇒ [tex]36[/tex]
Height, h = [tex](14)(3)[/tex]
⇒ [tex]42[/tex]
The formula of surface area of rectangular prism is
[tex]A=2(lw+wh+lh)[/tex]
⇒ [tex]2((54)(36)+(36)(42)+(42)(54))[/tex]
⇒ [tex]2(1944+1512+2268)[/tex]
⇒ [tex]2(5724)[/tex]
⇒ [tex]11448[/tex]
Hence we can conclude that the surface area of new rectangular prism is 11448 square inches.

[tex]24x^{2}+bx^{2} =25x^{2}[/tex]
Answer:
x = 0
Step-by-step explanation:
Subtract 25x^2 from both sides
24x^2 + bx^2 - 25x^2 - 25x^2
Simplify
bx^2 - x^2 = 0
Factor bx^2 - x^2: x^2(b - 1)
bx^2 - x^2
Factor out common term x^2
= x^2 (b - 1)
x^2(b - 1) = 0
Using the Zero Factor Principle: If ab = 0 then a = 0 or b = 0
x^2 = 0
Apply rule x^n = 0 x = 0
x = 0
a car company uses the table below to show customers the appropriate amount of gas used when a car has been driven a certain number of miles.
if the car always uses the same amount of gas each time, how many gallons of gas would be needed to travel 480 miles?
A. 20
B. 24
C. 33
D. 39
Answer:
B. 24
Step-by-step explanation:
This is a simple ratio.If 1 mile = 0.05 gallons of gasoline, then 480 miles = 24 gallons of gasoline!George was riding his bike by some construction, and apparently got a nail in his tire. 5 days later he realized that the tire was losing air, and at that time it had a pressure of 52 pounds per square inch (PSI); he didn t have time to x it then, and then 8 days after getting the nail the pressure was down to 46 PSI.
(a) Write a linear equation giving the tire pressure (P) in pounds per square inch in terms of the number d of days since he got the nail in his tire.
Answer:
P(d) = 62 - 2d
Step-by-step explanation:
P = pound per square inch
d = days
(52 - 46) / 3 = 2
46 + 2 * 8 = 62

3353 8. A survey showed that 1/3 of the students in the class liked blue 1/4 of the remainder liked red. The remaining 24 students liked yellow. How many students were in the class?
Answer: there are 48 students in the class
Step-by-step explanation:
let x = the total number of students in the class
1 - 1/3 = 2/3
1/4 * 2/3 = 2/12 = 1/6
1/3x + 1/6x + 24 = x
2/6x + 1/6x + 24 = x
3/6x + 24 = x
1/2x + 24 = x
24 = x - 1/2x
24 = 1/2x
24 * 2 = x
x = 48
there are 48 students in the class

Answer:
8 cm
Step-by-step explanation:
Ok lets on the biggest square we have 17 cm
17cm is the hypotenuse for the right triangle
The second largest's area is 225 cm^2
Sq root of 225 cm^2, is 15
To find x, lets plug the info we have to the pythagorean theorom
[tex]a^2 + b^2 = c^2\\a^2 + 15^2 = 17^2\\a^2 + 225 = 289\\\\289 - 225 = a^2\\64=a^2\\a = 8 cm[/tex]
