An art class is making a mural for their school which has a triangle drawn in the middle. The length of the bottom of the triangle is x. Another side is 13 more than times the length of the bottom of the triangle. The last side is 6 more than the bottom of the triangle. Write and simplify an expression for the perimeter of the triangle. What is the expression for the perimeter of the​ triangle?

Answer:

1.156 x 10^-6

Step-by-step explanation:

10^6 = 10x10x10x10x10x10 = 1000000

1.156 ÷ 1000000 = 0.000001156

if you simplify that the answer is 1.156 x 10^-6

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:

As we have to change it in simplest form,

3 days : 48 hours. Firstly, we have to convert days into hours ... So, 3 days = 3 × 24. => 72 hours ..... And Therefore,

72 : 48. And the fraction formed will be as follows :- And when we cut off it by 24, the resulting fraction will be :- So, The ratio will be, 3:2 ...

Answer:  CD: 8.5

Step-by-step explanation:6^2 = 36

Answer:

There were 2 1/2 inches of rain in 2 months.

Step-by-step explanation:

1. Reduce 1 6/12 to 1 1/2.

2. Add 1 1/2 and 1 (if it is easier for you to add decimals you can reduce the 1 1/2 to 1.5 by dividing 1 by 2. In that case you would get 2.5 as your final answer). The answer is 2 1/2.

Answer:

The answer is 1.

Step-by-step explanation:

look at the pic to see how I got it.

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:

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.

Hope this helps!

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:

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.
