The choose C. 9/8
I hope I helped you^_^
Answer:
A. 49/81
B. -66/5
C. 9/8
Step-by-step explanation:
Slide 1:
Dividing fractions is exactly the same as multiplying fractions, you just flip the second fraction so the expression becomes -7/9*7/-9 which is 49/81.
[tex]\frac{-7}{9}*\frac{7}{-9} =\frac{-49}{-81} =\frac{49}{81}[/tex]
Slide 2:
To make 22 a fraction you just put it over 1 to make 22/1 and you just multiply across. -66/5
Slide 3:
To transform a mixed number into an improper fraction, you multiply the denominator by the whole number and then add the numerator. You take that number and put it over the denominator. You should now have -9/2. Multiply across. Cancel out the negatives. 9/8

Cheryl is organizing her movie collection. If each movie case is 3/4 inch wide, how many movies can fit in a shelf 63 inch wide??
Answers
3/4in = 0.75in
60/0.75 = 80 movies
Answer:
84 movie cases
Step-by-step explanation:
Width of each movie case = 3/4 in
Width of shelf = 63 inch
Number of movie case = Width of shelf ÷ Width of each movie case
= 63 ÷ [tex]\dfrac{3}{4}[/tex]

The average 12-ounce container of blackberries contains 75 blackberries. Since the size of the blackberries can vary, the actual quantity of blackberries in a container can range anywhere from 2 berries below average to 2 berries above average.
Write and solve an absolute value equation to calculate the minimum and maximum blackberry quantities in a 12-ounce container.
Enter your answers in the boxes below.
Minimum Quantity: ?
blackberries
Maximum Quantity: ?
blackberries
Answers
77 maximum
The minimum and maximum blackberry quantities in a 12-ounce container will be 73 and 77 respectively.
What is inequality?A difference between two values indicates whether one is smaller, larger, or basically not similar to the other.
A mathematical phrase in which the sides are not equal is referred to as being unequal. In essence, a comparison of any two values reveals whether one is less than, larger than, or equal to the value on the opposite side of the equation.
Let's say the number of blackberries is x
Then,
If blackberries are above 2
Then,
x + 2 ≤ 75
x ≤ 73
And If blackberries are below 2
Then,
x - 2 ≤ 75
x ≤ 77
Hence "The minimum and maximum blackberry quantities in a 12-ounce container will be 73 and 77 respectively".

Determine if the lines are parallel, perpendicular, neither or the same line: y = -2x + 1 and -2x + 4y = 5.
Answers
Answer: These lines are perpendicular
Step-by-step explanation:
Let's use slope intercept form, y=mx+b (m=slope, b=y intercept)
Parallel lines have the same slope, or m
y=3x+7 and y=3x+32 are parallel because they have the same mPerpendicular lines have an opposite reciprocal slope
y=2x+13 and y= -1/2+2 are perpendicular because they are reciprocalsy=-2x+1 is already in slope intercept form. Let's change the other problem
-2x+4y=5isolate the y, 4y=2x+5make y by itself, y=2/4x+5/4 or y=1/2x+5/4Here are the two problems: y=-2x+1 and y=1/2x+5/4
Look closer. These lines are actually perpendicular.
Take the second problem's slope, 1/2. Make it a negative reciprocal, which means -2/1 or -2. These lines are perpendicular.

Find The value of H:
S=2πr(r+h)
Answers
Answer:
[S / (2πr)] - r = h
Step-by-step explanation:
You can't solve for H because there isn't a capital H in the equation. However, I'm going to pretend its "h" because that might have been a mistake.
S = 2πr(r + h)
Divide by 2πr to try to isolate h
S / (2πr) = r + h
Subtract r from both sides to get h by itself
[S / (2πr)] - r = h
That is your final answer.
[tex]\\ \rm\Rrightarrow S=2\pir(r+h)[/tex]
[tex]\\ \rm\Rrightarrow r+h=\dfrac{S}{2\pi r}[/tex]
[tex]\\ \rm\Rrightarrow h=\dfrac{S}{2\pi r}-r[/tex]
[tex]\\ \rm\Rightarrow h=\dfrac{S-2\pi r^2}{2\pi r}[/tex]
