There were 36 sweatshirts on sale for 2/3 of the regular price. What was
the sale price if the regular price was $30?
Answer:
To sum up, we solved for W. Finally, the sale price of a sweatshirt was 20$.
Step-by-step explanation:
So we have our main equation of W/G=p. The G stands for the total amount which is 30. The W is the unknown in this case. As for the p equals 2/3.
Thus we substitute G and p into the equation W/30=2/3. We multiply both sides of the equation with 30 W=2*30/3. Which gives us 60/3=20.
What is the slope of the line shown on the graph?
Answer:
Step-by-step explanation:
The slope, m, can be determined using any two points, and slope is defined as
m=(y2-y1)/(x2-x1), I’ll use (0,0) and (5,-1)
m=(-1-0)/(5-0)
m=-1/5

The floor of Catelyn's bedroom has an area of 123 1/2 square feet. The walls are 9 1/2 feet tall. What is the volume of Catelyn's bedroom?
Answer:
Volume of the Catelyn's bedroom = [tex]1173\frac{1}{4}[/tex] cubic feet
Step-by-step explanation:
Floor of Catelyn's bedroom has area = [tex]123\frac{1}{2}[/tex] square feet
= 123.5 square feet
Height of the walls = [tex]9\frac{1}{2}[/tex] feet
= 9.5 feet
Shape of the room is like a rectangular prism.
Therefore, volume of the bedroom = Area of the rectangular base × Height
= 123.5 × 9.5
= 1173.25
= [tex]1173\frac{1}{4}[/tex] cubic feet
You told your friend that you could eat 3/5 of a large pizza. If you only ate 1/2 of what you said you could eat, what fraction of a large pizza did you eat?

use the exponent rule to simplify
Answer:
[tex]y^{-5}[/tex]
Step-by-step explanation:
The Exponent Quotient Rule states that if two terms of the same base are being divided by each other, then the simplified expression is the base to the first power subtracted by the second power. As an algebraic equation, that would be [tex]\frac{x^{a} }{x^{b} } =x^{a-b[/tex], where [tex]x[/tex] is the common base and [tex]a[/tex] and [tex]b[/tex] are the exponents.
In this case, [tex]x=y[/tex], [tex]a=2[/tex], and [tex]b=7[/tex], so we know that [tex]\frac{y^{2} }{y^{7} } =y^{2-7}=y^{-5}[/tex]. Hope this helps!
find the measure of angle 1
Answer:
44°
Step-by-step explanation:
8x - 4 = 6x + 8 (This is because they are corresponding angles)
8x - 6x = 8 + 4
2x = 12
x = 12 ÷ 2
x = 6
6x + 8 = angle 1 (Vertically opposite angles are equal)
Substitute the value of x in the equation '6x +8' to get the size of the angle.
6 × 6 + 8
36 + 8 = 44°
Angle 1 = 44°
Write two different equations to describe each situation. a) You buy 3 identical shirts and 2 identical pairs of socks and spend $38.
Answer:
3x + 2y = 38, 3a + 2b = 38
Step-by-step explanation:
An equation may be defined as a statement that shows two mathematical expressions to be equal. It is to equate one thing to another thing.
In the context, two different equations for the situations are :
i). Let the shirt be represented by x
And the socks be represented by y
Therefore, according to the question,
3x + 2y = 38
ii). Let the shirt be represented by a
And the socks be represented by b
Therefore, according to the question,
3a + 2b = 38

Given the speeds of each runner below, determine who runs the fastest. Stephanie runs 10 feet per second. Brooke runs 192 feet in 24 seconds. Frank runs 1 mile in 449 seconds. Zach runs 817 feet in 1 minute.
Answer:
Step-by-step explanation:
speed of
Stephanie=10 ft/s
Brooke= 192/24=8 ft/s
Frank= (1×1760×3)/449≈11.76 ft/s
Zach=817/(1×60)≈13.62 ft/s
Zach runs fast.

Express the following in the form 10where n is an integer 10−8 × 10−6
Given:
The given expression is:
[tex]10^{-8}\times 10^{-6}[/tex]
To find:
The expression in the form of [tex]10^{-n}[/tex].
Solution:
We have,
[tex]10^{-8}\times 10^{-6}[/tex]
It can be written as
[tex]10^{-8}\times 10^{-6}=10^{-8+(-6)}[/tex] [tex][\because a^ma^n=a^{m+n}][/tex]
[tex]10^{-8}\times 10^{-6}=10^{-8-6}[/tex]
[tex]10^{-8}\times 10^{-6}=10^{-14}[/tex]
Therefore, the required value is [tex]10^{-14}[/tex].
Christina says that if she multiplies 23×25, her product will automatically be less than 23 because 25 is less than 1, meaning the product will only be a part of 23. Is Christina correct?
Answer:
Christina is incorrect.
Step-by-step explanation:
Since we are multiplying and our numbers are larger than 1, we know our product will be large. Your answer will be 575 :)

Solve the system of linear equations using multiplication.
- 4x + 3y
9
5x - 2y
29
The solution is
Answer:
(15,23)
Step-by-step explanation:
-4x+3y=9
5x-2y=29
Let's multiply the first equation by 2 and the second equation by 3, in order to have the same coefficient on y.
-8x+6y=18
15x-6y=87
Add these two equations together to eliminate y.
7x=105
x=15
Now, plug in x, to find y.
5(15)-2y=29
75-2y=29
-2y=-46
y=23

EXPLAIN YOUR ANSWER!!!!!! WILL BE GIVING OUT BRAINLIEST!!!!!!!!!!!!
Answer:
The answer is B. [tex]3\frac{1}{3} ft.[/tex]
Step-by-step explanation:
It states that the figures in the pair are similar
When you multiply 5*8 it gives you 40 on the first angle
If the figures are similar then the other angle will equal 40.
So we need to find out which number that is multiplied by 12 that will give you 40.
If we multiply [tex]12*3\frac{1}{3}[/tex], it should give you 40.
Convert The mixed number into a improper fraction:
3 1/3=3*3+1/3
=10/3
Convert the element into a fraction:
12/1*10/3
Factor the number:
3*4/1=10/3
Cross - cancel the common factor: 3
4/1*10/1
Apply the fraction rule:
4*10/1*1
Multiply the numbers: 4*10=40
=40/1*1
Multiply the numbers: 1*1=1
=40/1
Apply the Fraction rule:
=40

Step-by-step explanation:
At a farm four employees harvest 48 pounds of food over a certain number of hours each employee works the number of hours shown
Complete question :
At a farm, four employees harvest 48 pounds of food over a certain numbers of hours. Each employee works the numbered of hours shown. Employee A: 6 hours employee B: 4 hours employee C: 6 hours employee D: 8 hours The number of pounds of food harvested by each employee is proportional to the number of hours worked. Fill in the table with the amount of food, in pounds, each employee harvested.
Answer:
A = 12 lbs ;
B = 8 lbs
C = 12 lbs
D = 16 lbs
Step-by-step explanation:
Total hours worked :
(A + B + C + D)
(6 + 4 + 6 + 8) hours = 24 hours
Total pounds of food = 48 pounds
Pounds harvested per hour = 48 pounds / 24 hours = 2 pounds per hour
Amount of food harvested by each employee :
A = 6 * 2 = 12 pounds
B = 4 * 2 = 8 pounds
C = 6 * 2 = 12 pounds
D = 8 * 2 = 16 pounds
