find the area of each circle (use pi =3.14)

16mm ​

Answers

Answer 1

Answer:

200.96

803.84

Step-by-step explanation:

I wasn't sure if 16mm was the radius or diameter. If it's the diameter then use the first answer. If it was the radius then use the second answer.

In order to find the area of a circle use equation

[tex]A=\pi r^2[/tex]

r = radius, which is half of the line along the circle. If you have the diameter simply divide it by two and you have the radius.

What is tip would you give to your waiter if your bill was $56.50 and the tip is 20% of the bill

Answers

$11.30

Step-by-step explanation:

First, convert the 20% to an actual number that can be used in a calculation.

For percents, this is always done by simply dividing the percent (in this case 20%) by 100%.

So, the conversational term "20%" becomes 20% / 100% = 0.20 in terms of a real mathematical number.

Second, you need to find out what 20% of your $56.50 meal cost is. This is always done by multiplying 0.20 by $56.50, or

0.20 x $56.50 = $11.30

So, the amount of tip you are going to leave is $11.30.

This makes the total cost of your meal (to write on your charge slip or other payment)

$56.50 + $11.30 = $67.80.

Step-by-step explanation:

The Dot plot for Alia's Sample is plot D.

What is Dot plot?

Based on the values of each point, a dot plot visually groups the number of data points in a data set. Similar to a histogram or probability distribution function, this provides a visual representation of the data distribution.

Tasneem has a sample of 12 bags of candy.

Now, the median for Tasneem sample space is

= (47.1 + 47.2)/ 2

= 47. 15

As, the median mass in A is 47.05, B is 47.1, in C is 47.1 and in D is 47.4.

Also, we know that the median mass for Alia's Sample is greater than Tasneem.

Thus, the correct plot is D.

Answer:

B. s = 9 inches

Step-by-step explanation:

We are given a square with a perimeter of 36 inches, along with a key that the perimeter is given through the equation P = 4s, where "s" stands for the length of one side. We are then asked to find which number s is.

Perimeter is when you add 4 sides altogether, in our case we have 36 inches as our perimeter. Since 4s is the main factor as to how we got 36 inches, we need to set up one system equation.

P = 4s

36 = 4s

Now we need to find a number that multiplies with 4 to get us 36, simple as that. Let's get s alone to retrieve our answer :

36 = 4s

Divide 4 from both sides :

9 = s

s = 9

Problem PageQuestion A theater group made appearances in two cities. The hotel charge before tax in the second city was $1500 lower than in the first. The tax in the first city was 10%, and the tax in the second city was 8%. The total hotel tax paid for the two cities was $825. How much was the hotel charge in each city before tax?

Answers

Answer:

the hotel charge in the first city is $5250 while the hotel charge in the second city is $3750

Step-by-step explanation:

Let a represent the charge in the first city before tax and b represent the charge in the second city before tax.

Therefore tax in first city = 10% of a = 0.1a

Tax in second city = 8% of b = 0.08b

From the total tax as $825, hence:

0.1a + 0.08b = 825           (1)

The hotel charge before tax in the second city was $1500 lower than in the first. This gives the equation:

b = a - 1500

a - b = 1500                    (2)

To find a and b, solve equation 1 and 2 simultaneously. Multiply equation 2 by 0.1 and subtract from equation 1:

0.18b = 675

b = $3750

a = b + 1500 = 3750 + 1500 = 5250

a = $5250

Therefore, the hotel charge in the first city is $5250 while the hotel charge in the second city is $3750

Answers

Answer:

1. 18

2. 181

3. 101

Step-by-step explanation:

They want you to take each equation, and replace the letter with the number they give you after the equation.

3m + 2n + 4; m = 2, n = 4

This becomes

3(2) + 2(4) + 4

We multiply before we add, according to the order of operations. So next, the equation becomes:

6 + 8 + 4

= 18

———-

D^2 + 9k ; D = 10, k = 9

Numbers squared are numbers multiplied by themselves.

(10)(10) + 9(9)

= 100 + 81 = 181

——————-

3m + 4y x 2 ; m = 7, y = 10

3(7) + 4(10) x 2

21 + 40 x 2

Remember, multiplication always comes before addition.

21 + 80 = 101

Find 3[g(4)] if g(x) = -2x + 10

Answers

Answer:

6

Step-by-step explanation:

= 3[-2(4) + 10]

= 3(-8 + 10)

= 3(2)

The function is given as  g(x) = -2x + 10 then the solution of the 3[g(4)] would be equal to 6.

What is a function?

A function is a type of relation, or rule, that maps one input to a specific single output.

Functions that are formed by composing two or more functions in a way that one's output is another's input are called composite functions.

They are also called functions of functions.

We have to find 3[g(4)] if g(x) = -2x + 10

3[g(4)] = 3[-2(4) + 10]

3[g(4)]  = 3(-8 + 10)

Three paintings are shaped like an 8-foot square a 7-foot by 4-foot rectangle and a triangle with 6-foot base and height of 7 feet. If those paintings are hung together on the outside of the building how much of the building s wall they cover together ?

Answers

Answer:

113 square feet

Step-by-step explanation:

the total area covered can be determined by adding the area of the rectangle, triangle and square together

Area of a square = length² = 8² = 64 ft²

Area of a rectangle = length x width = 7 x 4 = 28 ft²

Area of a triangle = 1/2 x base x height = 1/2 x 6 x 7 = 21 ft²

64 + 28 + 21 = 113 ft²
