Jordan buys a video game on sale. The original price of the game is $40 and it is 20% off. How much did Jordan pay?
Answer:
$32
Step-by-step explanation:
If the video game is 40 dollars, then we divide that by 5, since 20*5 makes 100%. 40/5=8 so then we subtract 8 from the original 40 since it's 20% off.

Step-by-step explanation: The median is the middle number in a sorted, ascending or descending, list of numbers and can be more descriptive of that data set than the average. Write all of the numbers and cross out a even amount of numbers on both sides. Image 1 shows your problem. If your problem had another number, you solve it differently. Check image 2.
Amanda increased the amount of protein she eats every day from 48g to 54g. By what percentage did Amanda increase the amount of protein she eats? 11.1%
Answer:
12.5%
Step-by-step explanation:
Previous grams of protein = 48g
Present grams of protein = 54g
By what percentage did Amanda increase the amount of protein she eats?
Percentage increase in the amount of protein = (present grams - previous grams) / previous grams × 100
= (54g - 48g) / 48g × 100
= 6g/48g × 100
= 1/8 × 100
= 0.125 × 100
= 12.5%
Percentage increase in the amount of protein = 12.5%

Answer:
2(√17b³ )c⁵
Step-by-step explanation:
We are to simplify the expression given below
√68b³c¹⁰
Simplifying 68
= √(17 × 4)b³c¹⁰
Hence
= 2√17b³c¹⁰
= 2 √17b³ × √c¹⁰
= 2 √17b³ × c¹⁰/²
= 2(√17b³ )c⁵
Nine tokens are black on one side and white on the another initially four tokens have the blackside upwards in each turn tell the least number of turns yo need to have all tokens showing the same colour
Answer:
2
Step-by-step explanation:
Let us name the white chips "W" and the black ones "B". If there are 9 tiles and 4 are in black then the rest, that is 5, in white, like this:
B-B-B-B-W-W-W-W-W
First movement, in turn we can flip 3 tiles, in this case we flip two blacks and one white, it would look like this:
W-W-B-B-B-W-W-W-W
The second movement is to turn the 3 black ones and thus they would all be blank
W-W-W-W-W-W-W-W-W
This means that, the smallest number of movements is 2.

Answer:
x = number of students in each van = 16
y = number of students in each bus = 47
(bus, van) = (47, 16)
Step-by-step explanation:
Let
x = number of students in each van
y = number of students in each bus
This can be represented by the equation
7x + 6y = 394 (1)
3x + 12y = 612 (2)
Using elimination method
Multiply (1) by 2
14x + 12y = 788 (3)
3x + 12y = 612 (2)
Subtract (2) from (3) to eliminate y
14x - 3x = 788 - 612
11x = 176
x = 176/11
x = 16
Substitute x = 16 into (1)
7x + 6y = 394 (1)
7(16) + 6y = 394
112 + 6y = 394
6y = 394 - 112
6y = 282
y = 282/6
y = 47
x = number of students in each van = 16
y = number of students in each bus = 47
(bus, van) = (47, 16)

Jennifer is mowing the lawn. After 15 minutes, or 14 of an hour, Jennifer has mowed 23 of the lawn. At this rate, how long will it take Jennifer to mow the entire lawn?
Answer:
[tex]22.5\:\text{minutes}[/tex]
Step-by-step explanation:
In 15 minutes, Jennifer has mowed [tex]\frac{2}{3}[/tex] of the lawn (given in problem). This means that it will take her [tex]\frac{3}{2}\cdot 15=22.5\:\text{minutes}[/tex] to mow the entire lawn, assuming a constant rate.
Equation:
Let [tex]x[/tex] represent the entire lawn:
[tex]\frac{2}{3}x=15,\\x=\frac{15}{\frac{2}{3}}=15\cdot \frac{3}{2}=\boxed{22.5}[/tex]

Maggie found the area of the irregular figure by dividing it into a triangle and a rectangle.
A figure can be broken into a rectangle and triangle. The rectangle has a base of 6 centimeters and height of 5 centimeters. The triangle has a base of 3 centimeters and height of 2 centimeters.
Her work is shown below.
Area of rectangle = bh = (6 cm)(5 cm) = 30 Centimeters squared
Area of triangle = bh = (2 cm)(3 cm) = 6 Centimeters squared
Area of entire figure = 30 Centimeters squared + 6 Centimeters squared = 36 Centimeters squared
Which best describes the error that Maggie made?
She didn’t use the correct formula for the area of the triangle.
She didn’t use the correct formula for the area of the rectangle.
She didn’t find the dimensions of the triangle correctly.
She didn’t combine the areas of the triangle and the rectangle correctly

Step-by-step explanation:
Jeremy made one vertical stack of boxes that had a surface area of 17,052 square centimeters. How many shoe boxes were in the stack?
Answer:
there are 7 boxes in the stack.
Step-by-step explanation:
After a quick online search, I've found that the dimensions of each box are:
Height = H = 18cm
Length = L = 40cm
Width = W = 21cm
If we stack the boxes, then the only thing that changes in the figure is the height, so if we stack N boxes, the dimensions will be:
Height = H = N*18cm
Length = L = 40cm
Width = W = 21cm
And for a rectangular prism of height H, width W, and length L, the surface is:
S = 2*(H*W + W*L + H*L)
Then for our stack of boxes, the surface is:
S = 2*(40cm*21cm + 40cm*N*18cm + 21cm*N*18cm)
And we know that the total surface is 17,052 cm^2
Then we just need to solve:
2*(40cm*21cm + 40cm*N*18cm + 21cm*N*18cm) = 17,052 cm^2
(40cm*21cm + 40cm*N*18cm + 21cm*N*18cm) = (17,052 cm^2)/2
(40cm*21cm + 40cm*N*18cm + 21cm*N*18cm) = 8,526 cm^2
840 cm^2 + N*720 cm^2 + N*378 cm^2 = 8,526 cm^2
N*(720 cm^2 + 378 cm^2) = 8,526 cm^2 - 840 cm^2 = 7,686 cm^2
N*(1,098 cm^2) = 7,686 cm^2
N = (7,686 cm^2)/(1,098 cm^2) = 7
So there are 7 boxes in the stack.

A goat and a cow together weigh 190 kg 640 g. The weight of the goat is 59 kg 720 g. Find the weight of the cow
Answer: 130 kg 920 g
Step-by-step explanation:
Given
The weight of the goat is 59 kg 720 g
The combined weight of goat and cow is 190 kg 640 g
Suppose, the weight of the cow is x kg
We know, 1 kg=1000 g
Converting weight into kg
Goat weight
[tex]=59+0.720\\=59.720\ kg[/tex]
Total weight
[tex]=190+0.640\\=190.640\ kg[/tex]
Then, the cow weight is given by
[tex]\Rightarrow 190.640-59.720\\\Rightarrow 130.920\ kg\ \text{or}\ 130\ kg\ 920\ g[/tex]

Nicholas is buying shirts for his baseball team. He will pay $8.75 for each shirt plus a one-time fee of $25 for the design. Write an equation that can be used to find y, the total cost to buy x shirts.
Answer:He will pay $9.50 for each shirt plus a one-time fee of $22.50 for the design.
Which equation can be used to find y, the total cost to buy x shirts?
A) y = 9.5x + 22.5
B) y =22.5x + 9.5
C) y = 9.5x - 22.5
D) y =22.5x - 9.5
He would use equation A.
Step-by-step explanation:If each shirt cost 9.50 you would multiply that by how many shirts you have plus the one time fee of 22.50 you would get the equation y= 9.5x + 22.5
