Part A

To find the area of the unshaded region, subtract the area of the  shaded region   from the sum of the areas of the   rectangle   and   semicircle  

----------------

Explanation:

When it comes to area problems, think of a grid of squares. Let's say we had a 10 by 10 grid of tiny squares (10*10 = 100 total). Now let's say 8 of them are shaded in. There are 100 - 8 = 92 unshaded squares to represent the total area of the unshaded region.

That's effectively what's going on with this problem as well. Sure things get a bit tricky with that curved portion on top, but we can still get an approximation if we use smaller and smaller grid sizes. I recommend using graph paper or graphing software that provides a grid.

========================================================

Part B

----------------

Explanation:

For now, I'm going to ignore the shaded region. I'll come back to it later.

The rectangle is 15 ft by 50 ft. It has an area of length*width = 15*50 = 750 sq ft.

The semicircle up top has an area of [tex]0.5*\pi r^2 = 0.5*\pi*(7.5)^2 \approx 88.3573[/tex]  sq ft approximately. The 7.5 is from dividing the diameter in half to get the radius. As the instructions stated, I used the calculator's version of pi.

The rectangle and semicircle have their areas add to

750+88.3573 = 838.3573

Now we can finally address the shaded region. It is a 3 ft by 9 ft rectangle because "the length is 3 times the width" and the width is 3 ft. This shaded rectangle has area 3*9 = 27 sq ft.

The unshaded region is:

unshaded = total - shaded = 838.3573 - 27 = 811.3573

This rounds to the final answer of 811

Answer:

3x^2+21/2

Step-by-step explanation:

3x^2+1/2*7(3)

(a)=a so (3)=3

3x^2+1/2*7*3

1/2*7*3=21/2

3x^2+21/2

Answer:

— The total cost for a reward program member to see 5 movies is $40 and the total cost for 12 movies is $75. Assume the relationship

Step-by-step explanation:

The equation of the function is y = 5x+5, where x represents the number of movies and y represents the total cost.

An equation is a mathematical statement that shows that two mathematical expressions are equal.

Given that, The total cost for a reward program member to see 5 movies is $40.00 and a total costs for 12 movies is $75.00.

The coordinates of the equation can be (5, 40) and (12, 75)

The equation of a line passing from two points is given by,

y-y₁ = (y₂-y₁)/(x₂-x₁)(x-x₁)

y-40 = (75-40)/(12-5)(x-5)

y-40 = 35/7(x-5)

y = 5x-25+40

y = 5x+15

Hence, the required equation is y = 5x+15

Answer:

1

Step-by-step explanation:

Equations to remember:

Length · Width · Height = Volume

LWH = V

---------------------------------------------------

Length = 5/4

Width = 4/3

Height = 3/5

Your equation will look something like this:

[tex]\frac{5}{4} * \frac{4}{3} * \frac{3}{5} = V[/tex]

or

[tex]\frac{5*4*3}{4*3*5} = V[/tex]

----------------------------------------------------

The simple thing about this problem is that, no matter what order they're in, you're multiplying the same numbers on the top and the bottom. Whatever the top is (5*4*3), the bottom will be (4*3*5). If the top and bottom are equal, that means that you'll have a whole number of 1.

----------------------------------------------------

NOMINATORS

[tex]5 * 4 = 20\\20 * 3 = 60[/tex]

So the top will be 60.

----------------------------------------------------

DENOMINATORS

[tex]4 * 3 = 12\\12 * 5 = 60[/tex]

The bottom will also be 60.

-----------------------------------------------------

[tex]\frac{60}{60} = \frac{1}{1} = 1[/tex]

So your answer will be [tex]1cm^{3}[/tex]!

Answer:

811.99x1.065=864.77

Step-by-step explanation:

Since it is a sales tax, and not something else, we would add a 1 on the front of it, to essentially just "add" back that 811.99, even though it is multiplication. 1.065 times 811.99 is the same as (811.99x.065)+811.99.

Answer:

36 mins

Step-by-step explanation:

7:15 - 6:39 = 36 mins

She finished the race in 36 mins.

Have a good day/night

Answer:

36 minutes

Step-by-step explanation:

You subtract the time she started from the time she finished.

So, it would be 7:15 - 6:39.

It would be easier to find the number that, when added to 6:39, results to 7:00. 

To do so, you subtract 39 from 60.

60 - 39 = 21 minutes

Now, add 21 to 15.

21 + 15 = 36 minutes

Therefore, it took her 36 minutes to complete the race.
