Answer 1

Answer:

120πcm²

Step-by-step explanation:

Since we are keeping this in terms of pi, you do not necessarily need a calculator. I will be doing my calculations as simple as I can.

First we need to figure out the area of the top circle and bottom circle.

We know that the formula for the area of a circle is:

πr²

So we need both circles, our formula becomes:

2πr²

Let's substite our radius in.

2 × π × 4² = 32πcm²

Now we need to find the area of the sides itself. Our formula here is:

2 × π × r × h

Let's substitute our radius and height in:

2 × π × 4 × 11 = 88πcm²

Let's now add both of these together:

88πcm² + 32πcm² = 120cm²

Remember to add your measurements!

Hope this helped!

Mark's bill for lunch at a restaurant is $14.50, and he wants to leave a 18% tip.
How much should he leave for the tip?

A. $2.18

B. $2.61

C. $11.60

D. $261.00

Answers

It’s B because you divide 18 percent from 14.50 dollars.
It would be B. Because 14.50 times .18 equals 2.61. Just put a decimal on it and move it to the right twice and multiply that by 14.50. If you need a better explanation you can message me! Hope this helps!:)

Mr. Jackson has a total of 12 employees. He wants to buy each employee 3 aprons that will cost $7.79 each, 1 cap that will cost $5.68, and a t-shirt that costs $13.99. How much will Mr. Jackson need to spend to purchase the items for his employees?

Answers

12/3 is 4 so multiply each by 4 so 7.79 x 4 is 31.16 5.68x4 22.72 13.99x4 55.96


31.16 + 22.72+ 55.96

Answer: $109.84

Answer: $516.48

Step-by-step explanation: Multiply 7.79 by 3 because it's 3 for each employee then multiply by 12 for each employee which equals 280.44. then 5.68 x 12 which is 68.16 for the cap. then 13.99 x 12 for the shirt which is 167.88. add 280.44, 68.16, and 167.88 to get 516.48.

1 floor per 13 feet.

It means how many floors are to be allocated in a certain area of space.

Step-by-step explanation:

Answer:


Meaning: Each floor of the buiding has a height of 15 feet.
Step-by-step explanation:
The missing figure is attached.
By definition, the ratios are used to compare two or more things or quantities.
In this case you must write the ratio of height of the building to the number of floors it has.
You can observe in the figure that the building has a height of 135 feet, and, since it has 9 floors, you can write the following ratio:

Therefore, dividing the numerator by the denominator, you get that the unit rate is:

This means that each floor of the buiding has a height of 15 feet

an isosceles triangle is when 2 angles are the same measure. an triangles angle equal to 180 degrees. therefore angle A is 80 degrees as well as angle B equals 80 degrees. since the angles of a triangle equal to 180 you subtract the two known angles to find angle C. So 180-80-80 which equals to 20.


Therefore angle C=20 degrees

Hello again davetriona12! I can help you.

We have 2.99, 3.19, 3.39, and 3.79

In order to solve this, we need to find out how much is being added every time. To do this, we will subtract 2.99 from 3.19 which gives us 0.20

So each time, 0.20 gets added.

Now that we have that information, we are ready to find the blanks.

For the first blank, we will subtract 2.99 - 0.20 which will give you 2.79

For the second blank, we will add 0.20 to 3.39 which will give you 3.59

Hope this helps you!

y = 3x

y = x + 3




In y = 3x, the value of y is 3 times the value of x, and in y = x + 3, the value of y is 3 more than the value of x.

In y = 3x, the value of y is 3 more than the value of x, and in y = x + 3, the value of y is 3 times the value of x.

In y = 3x and y = x + 3, the value of y is 3 more than the value of x.

In y = 3x and y = x + 3, the value of y is 3 times more than the value of x.
