A runner saved $25 when he purchased a pair of tennis shoes on sale. If the sale price was 35% off the regular price, what was the regular price of the tennis shoes?
Given:
Amount saved in sale = $25
Sale price was 35% off the regular price.
To find:
The regular price of the tennis shoes.
Solution:
Let the regular price of the tennis shoes be x.
Sale price was 35% off the regular price.
[tex]Discount=\dfrac{35}{100}x[/tex]
Amount saved in sale = $25
[tex]0.35x=25[/tex]
Divide both sides by 0.35.
[tex]x=\dfrac{25}{0.35}[/tex]
[tex]x=71.42857[/tex]
[tex]x\approx 71.43[/tex]
Therefore, the regular price of the tennis shoes is $71.43.
6. You have 220 feet of fencing material to enclose a rectangular area for your pet animals. Let x = the length of the rectangular enclosure. (a) [7 points] Set up the function A(x) that represent the enclosed area. (b) [7 points] What should be the dimensions of the enclosed area? (c) [2 points] What is the maximum area of the enclosed area?
Answer:
I will start with (c)
(c) What is the maximum area of the enclosed area?
the maximum area of a rectangle is always given by a square figure
since the square has 4 equal sides, each side will be 220 / 4 = 55 ft long
maximum area = 55 x 55 = 3,025 ft²
(b) What should be the dimensions of the enclosed area?
the dimensions would be 55 ft in length by 55 ft in width
(a) Set up the function A(x) that represent the enclosed area.
perimeter of the rectangle = 220
we have 4 equal sides, so
A(x) = x²
Which word describes the slope of the line?
Answer:
rate of change
Step-by-step explanation:
Answer:
"rise over run" or "rate of change"
Step-by-step explanation:
"Slope" itself is "rise over run", or how quickly the line moves up or down relative to the x-axis as the value of x changes.
A gradient is really just another name for slope, not a description OF a slope.

the linear equation is y= -4/3x + 2
Answer:
y=-x+2
Step-by-step explanation:
Which equation represents the relationship “4 less than a number is 10?”
Answer:
x - 4 = 10
x = 14
Step-by-step explanation:
Any variable can be used to represent the number, I choose to use "x" in this case.
x - 4 = 10
Inverse operations;
x - 4 = 10

Answer:
A I soo sorry but I really can't solve this I have not learned it yet
Answer: 11x-10y
Step-by-step explanation:
Combine like terms.
(5x+3y)-(2x-7y)+8x
3x + 8x
Remember to distribute the negative.
-(-7y) = +7y
3y +7y
Combine like terms once again.
3x+8x= 11x and 3y+7y= 10y
what is 3.78 plus 8.94
Answer:
The answer is 12.72 hope this helps
Step-by-step explanation:
You'll add them it's just like simple addition but you just have to know where the decimal point will be after adding
3.78
+8.94
12.72
When you are adding you start from the back with back I mean the end so when you add 8 plus 4 it's going to be 12 then you write or type the 2 and then carry the 1 and add it to the 7 which is going to be 8 then you add the 8 to the 9 which is going to be 17 that's why we have the 7 there then you carry 1 and add it to the 3 which is going to be 4 and then 4+8 is going to be;12
That's how we got the 12.72

The dot plot shows the number of classes per semester that a group of boys and girls have chosen to take in their freshman year of college. Which statements correctly describe the two data sets?
The difference of the means is 1.5.
The difference of the means is 0.5.
The difference of the means is about one-third the mean absolute deviation of either data set.
The difference of the means is 1.
The difference of the means is about one-half the mean absolute deviation of either data set.
The correct statement is the difference of the means is 0.5.
What is Box- plot?A box and whisker plot, often known as a box plot, shows a data set's five-number summary. The minimum, first quartile, median, third quartile, and maximum make up the five-number summary. A box is drawn from the first quartile to the third quartile in a box plot. At the median, a vertical line passes through the box.
Given:
As, from the box plot mean of boys is
= (1 x3 + 2x 7 + 3 x 6+ 4 x 2 + 5 + 6) /20
= 2.7
and, mean absolute deviation of boys
= (1.7 x 3 + 0.7 x 7 + 0.3 x 6 + 1.3 x 2 + 2.3 + 3.3)/ 20
= 1
now, from the box plot mean of girls is
= (1 x 2 + 2 x 4 + 3 x 7+ 4 x 4 + 1 x 5 + 6 x 2) /20
= 3.2
and, mean absolute deviation of girls
= (2.2 x 2+ 1.2 x 4 + 0.2 x 7+ 0.8 x 4 + 1.8 x 1+ 2.8x 2)/ 20
= 1.06

Does Each Equation Demonstrate The Distributive Property? Explain.
1) -2( x + 1 ) = -2x -2
2) (s - 4) 8 = 8 ( s - 4)
3) 5n - 45 = 5 ( n - 9 )
4) 8 + ( t + 6) = ( 8 + t ) + 6
[tex](42 \times 51) + 14 = [/tex]
Answer:
All of them demonstrate the distributive property, except for number 4. 1-3 all have a number on the outside of the parenthesis to distribute itself to the number and variable within the parenthesis, while #4 has a plus sign outside each pair of parenthesis, making you unable to distribute those numbers.

What's the answer to this?
Answer:
steeper
Step-by-step explanation:
D) Vertically compressed
E) Flatter
=====================================================
Explanation:
An example would be if a = 0.5 which leads to the graph being half as tall as it used to be since 1/2 = 0.5; notice how a = 0.5 makes 0 < a < 1 true. Since the graph is squished vertically, the graph is flatter.
We don't have a reflection over the x axis since 'a' is not negative.
----------------
Extra info:
If a > 1 then the graph is stretched vertically to make it taller than it used to be. Eg: a = 5 leads to the graph being 5 times taller than before which also would make it steeper too. The value of d handles the vertical shifting. If d > 0, then we shift up d units. If d < 0, then we shift down |d| units.Can someone help me on this pls?
