The area of the shaded region is 80 square centimeters.
The shaded region is insider a rectangle.
The rectangle has length of 12+2, 14 cm and width of 6+4, 10 cm.
Area of rectangle = length× width
=14×10
=140 square centimeters.
There are triangles in corners.
Area of triangle =1/2×4×12
=24 square centimeters.
There are two triangles with same measurements.
Area of triangle 1= 24×2 = 48 square centimeters.
Area of triangle 2=1/2×2×6
=6
It has two triangles= 2×6=12 square centimeters.
Area of shaded region = 140-12-48
=80 square centimeters.

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]
[tex]= 63 *\dfrac{4}{3}\\\\= 21 * 4\\\\= 84[/tex]

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.
The graph will show the height of the red car as the time increases. Predict what this graph will look like before pressing start to run the ferris wheel.
How long does it take for the person riding the ferris wheel to make a complete revolution?
One revolution is ____
0 seconds
30 seconds
60 seconds
or
80 seconds
Answers
As per the graph, the time it takes for the person riding the ferris wheel to make a complete revolution is typically 60 seconds.
When the ferris wheel starts, the height of the red car will initially increase as it ascends from the ground level. As the ferris wheel continues to turn, the red car will reach its maximum height, usually at the topmost position of the ferris wheel, and then descend back to the ground level. This motion will repeat as the ferris wheel continues to rotate.
Now, let's determine how long it takes for the person riding the ferris wheel to make a complete revolution. One revolution corresponds to the time it takes for the ferris wheel to complete one full cycle of motion, going from its initial position, through its highest point, and back to its initial position. This time can be calculated by finding the time period of the sinusoidal function representing the height of the red car.
To find the time period, we need to know the duration for one complete cycle of the sine wave, which is the time it takes for the ferris wheel to complete one revolution. The time period can be derived from the angular speed of the ferris wheel. If we know the angular speed (usually given in rotations per minute or radians per second), we can calculate the time it takes for one revolution.

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".

Label B - No change
Label C - Decreasing
Step-by-step explanation:
Line A is going up so the speed is increasing.
Line B is just a straight line so there is no change.
Line C is going down so the speed is decreasing.
Answer:
Increasing no change decreasing

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
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]
