Answer:
2 13/14 feet
Step-by-step explanation:
The remaining length is the difference between the starting length and the amount cut off:
5 3/7 - 2 1/2 = (5 -2) +(3/7 -1/2) = 3 +((3·2-7·1)/(7·2)) = 3 -1/14
= 2 13/14 . . . feet remaining

Addition and subtraction of fractions can be accomplished using a formula that does not rely on finding a least common denominator. In this case, the denominators have no common factors, so their product is, in fact, the least common denominator.

x2=−0.73
What is the solution to the equation?
Enter your answer as a decimal in the box.
x =
x = -0.365 (If its x(2)=-0.73)
How I solved it:
x^2=-0.73
-0.73÷2=-0.365
//
-0.365×2=-0.73
Therefore, the answer is -0.365.
Answer:
x = -1.46 (if its x/2=-0.73)
x/2=-0.73
-0.73x2=-1.46
therefore,
-1.46/2=-0.73

a^-13/ a^-6= ?
Rewrite the expression in the form a^n
Answer:
a^-7
Step-by-step explanation:
so when dividing exponents you subtract them so the exponents are -13 and -6 you would just subtract them
-13 - (-6) = -13 + 6 = -7
and so a^-7 is ur answer

Answer:
5.8
miles
Step-by-step explanation:
Since area is l×b or l×l since its a square(sides are equal) we can conclude that S×S=33.64
Another way to represent this is
[tex] {s}^{2} = 33.64[/tex]
to get S we can square root both sides
[tex]s = \sqrt{33.64} [/tex]
[tex] \sqrt{33.64} = 5.8[/tex]
Therefore S=5.8miles

A cash card has a starting value of $25. If the card is not used within the first year of its purchase, the value on the card begins to decrease by $2.50 per month.
The relationship between the number of months after the first year and the amount remaining on the card is .
The independent variable is the _____________?
The dependent variable is the ______________?
Answer:
The relationship between the number of months after the first year and the amount on the remaining card is linear and inverse ( Which meant that ,when the number of months after the first year increases , the amount on the remaining car decreases , in a linear way ) .The Independent variable is the numbers of months after the first year .The Dependent variable is the amount on the remaining card , Bcoz this amount depends on the time it has passed since the first year , ( which is our independent variable!).If we call "Y" our dependent variables and "X" our Independent variable , This relationship can be written as Y= 25 - 2.5x.If no months had passed since the first year, then x= 0 and the amount in the card equals $25 , While if one month has passed since the first year x= 1 and y= 22.5 ( The amount in the card in this case is $22.5 .Step-by-step explanation:

In the original equation, x is a variable, hence f(x). If that term in the parenthesis changes, such as to 0 or -2, we will plug in that number in place of the current variable.
f(0) = 4(0)^2 + 3 = 0 + 3 = 3
f(-2) = 4(-2)^2 + 3 = 4(4) + 3 = 16 + 3 = 19

6 A clothing store paid $30 for a jacket, and sold the jacket for $48.
What was the percent increase?
Answer:
60%
Step-by-step explanation:
% increase = Increase ÷ Original Number × 100
Answer:
60%
Step-by-step explanation:
Total increase in cost = $(48 - 30) = $18
Now,
% increase = Increase/Original amount × 100
=> 18/30 × 100
=> 18/3 × 10
=> 6 × 10
=> 60%

What is the slope of the line in this graph?
The slope of the line 5/7.
How do i know this?
Well the slope of a line is considered as rise/run.
So we start at the beginning and then go up until the line intersects a corner again. Then we mark that down.
Go back to the beginning and count how many times it takes to reach the height of the intersected corner. So it is 5.
Then we go to the right until we reach the point. And it takes 7 squares to reach it, so the slope it 5/7.
Your welcome! :D

the perimeter of a square is 72 inches, what is its area?
Answer:
A = 324 in²
Step-by-step explanation:
A square has 4 congruent sides s , then
s = 72 ÷ 4 = 18 in
The area (A) of a square is calculated as
A = s² = 18² = 324 in²
Shira’s Shoes sold 875,000 pairs of sandals in June, which was 70% of the total number of shoes sold. How many shoes did the company sell in June? Analyze Emily’s calculations. What error did she make? StartFraction part Over whole EndFraction = StartFraction 70 times 8,750 Over 100 times 8,750 EndFraction = StartFraction 612,500 Over 875,000 EndFraction.
Answer:
1,250,000
Step-by-step explanation:
875,000 sandals account for 70% of the total pairs sold.
875,000/7 = 125,000
125,000 accounts for 10%.
125,000 * 10 = 1,250,000.
1,250,000 accounts for 100%.
The company sells pairs of shoes in June is 612,500
In Emily's calculation the error she makes in the second last steps she forgets to write the term 70.
Given that,
Shiras Shoes sold 875,000 pairs of sandals in June, which was 70% of the total number of shoes sold.
We have to determine,
How many shoes did the company sell in June? Analyze Emily's calculations. What error did she make?
According to the question,
Shiras Shoes sold 875,000 pairs of sandals in June, which was 70% of the total number of shoes sold.
Then,
The shoes did the company sell in June is,
[tex]= \dfrac{70} {100}\times 875,000\\\\=8750 \times 70 \\\\= 612,500[/tex]
Hence, The company's sells pair of shoes in June is 612,500.
