Answer:

A = 22.0 in²

Step-by-step explanation:

The area-of-a-circle formula is A = (pi)r², where r is the radius.  The area of a semicircle is A = (1/2)(pi)r².

In this case (semicircular window), the area is

A = (1/2)(3.14)(14 in) = 21.98 in².  To the nearest tenth, that's A = 22.0 in²

Knowing the surface of an object would be useful for:

- the amount of paint needed to paint a room

- how much wrapping paper a gift will need

What is Surface Area?

Surface area is the total area covering the outside of a 3D shape.

By knowing this number, we can count the amount of paint needed to paint a room, how much wrapping paper a gift will need, etc.

On the other side, when we talk about the amount of water needed to fill an aquarium, how many watermelons fit in a box for shipping, the amount of gasoline left in the tank of vehicle, etc. we have to know the volume of the related variables.

scale factor = larger figure dimensions ÷ smaller figure dimensions

Answer:

167

Step-by-step explanation:

12 inches in 1 foot

60 feet divided by 4.3 inches = about 167

The ball would roll about 167 times

Answer:

A. 375 feet

Step-by-step explanation:

because threratio make feet 3 times longer you should multipy 3 by 125

125 x 3 = 375

Answer:

Part A: Divide the number of inches by 12 to convert to feet

Part B: 42

Step-by-step explanation:

There are 12 inces in a foot, so you would have to divide to geth te total feet.

Convert the inces into feet

144 in = 12 ft

108 in - 9ft

Remember that a rectangle have 2 pairs of equal sides so you would have the side lenghts of: 12ft, 12ft, 9 ft, 9 ft

then you add all of them togeter making it: 42 feet

Answer:

if we have to find circumference then ik how to do it

7. So the answer would be 37.68

Step by step explanation: The circumference of a circle formula is 2 x π x the radius which in this case is 6 so the answer is 37.68

8. So the answer would be 43.96

Step by step explanation: The circumference of a circle formula is 2 x π x the radius and in this case we are given the diameter and half of the diameter would be the radius so the diameter in this case is 14 and the half of it would be 7 so 2 x π x 7 which would be 43.96

9. So the answer would be 18.84

Step by step explanation: The circumference of a circle formula is 2 x π x the radius and in this case we are given the diameter and half of the diameter would be the radius so the diameter in this case is 6 and the half of it would be 3 so 2 x π x 3 which is 18.84.

10. So the answer would be 31.4

Step by step explanation: The circumference of a circle formula is 2 x π x the radius which in this case is 5 so the answer is 31.4.

11. So the answer would be 113.04

Step by step explanation:  The circumference of a circle formula is 2 x π x the radius which in this case is 18 so the answer is 113.04

12. So the answer would be 26.376.

Step by step explanation:  The circumference of a circle formula is 2 x π x the radius and in this case we are given the diameter and half of the diameter would be the radius so the diameter in this case is 4.2 and the half of it would be  so 2 x π x 4.2 which is 26.376.

Answer:

Explanation:

You subtract the biggest number you have (that are marked) and the smallest number (you have marked). So 10 - 1 =9

Answer: 1.) is $0.35

2.) is 2

3.) is $1.05

4.) is 8

Answer:

This is pretty much trial and error,

Step-by-step explanation:

what you are doing is trying to make the question true. So if you're trying to make 30 - 4 x 2 + 5 =2 true, you need to try to put parentheses in the right place, because Wwhatever you see in parentheses you have to do first. For example, the answer to the first question is 30 - 4 x (2+5) =2. The reason is 2 + 5 = 7, and 7 × 4 = 28, and 30 - 28 is 2. To help with order of operations, remember the term Please Excuse My Dear Aunt Sally (P for parentheses, E for exponent (if you're here yet), M for multiplication, D for division, A for addition, and S for subtraction). Here are the other answers:

17 - (8 - 5) = 14

(30 - 4) × 2 + 5 = 57

17 - 8 - 5 = 4

Answer: i would say L and W

Step-by-step explanation:

Vertical angles are a pair of opposite angles formed by intersecting lines.

L and W are the same length apart so i would say L and W

it is 20

you divide 2,12 then its 6 then 6 divided by 24 equals 4 then 4 times 5 equals 20

The Answer (maybe) :

Hello there, I am here to help you with your question :)

Answer: The person's speed is 8 miles per hour.

Step-by-step explanation:

To solve we want to convert the [tex]\frac{1}{8}[/tex] and [tex]\frac{1}{64}[/tex] proportionally for the number of miles per hour. We know that multiplying a fraction by its reciprocal will equal 1. So let's do that for the value of the hour.

[tex]\frac{1}{64}[/tex]×[tex]\frac{64}{1} =\frac{64}{64} =1[/tex]

Since we multiplied that to the number of hours we must also do that for the number of miles.

[tex]\frac{1}{8}[/tex]×[tex]\frac{64}{1} =\frac{64}{8} =8[/tex]

Answer:

According to the National Cancer Institute, the average cost of a pack of cigarettes is $6.28, which means a pack-a-day habit sets you back $188 per month or $2,292 per year.

So we times that by two which would be $4,584 a year.

With this amount of money you could purchase a stocks, jewlery, car, or anything else that is under that amount.

Answer:

1. Multiply the number of candies sold by 8

2. Multiply the number of servings by 20

Step-by-step explanation:

Hello!

We can approach this problem by looking at the first column in Question 1.

We can see that 10 is multiplied by 8 to get to 80, and 20 is multiplied by 8 to get to 160. We can assume this is a pattern because it repeats twice.

So we multiply by 8 for the first question.

We see that for every increase of 30 servings, the pretzels increase by 600.

We simply divide 600 by 30, to find our multiplier of 20.

So we multiply by 20 for the second question.

first put them in sequential order so it would be

10, 10, 15, 15, 16, 18, 23

okay Then, divide the sequence into the 1st and 3rd quartiles.  the median would be 15 becuase it is the middle.

1st - 10

3rd - 18

then you subtract

18 - 10 = 8

your  answer is 8 this should help you with your other ones  hope this helps you

Answer:

The first thing you need to do is, have a square whose area is 11² = 121 square inches. Then we are going to multiply the radius by π which is 3.14 the area of the circle with the radius 4 is equal to 3.14 × 4² = 3.14 × 16 = 50.24, you need to divide the calculated radius times π (3.14) you can get the answer and you need to round your answer to the nearest hundredth probability that the dart will hit within the circle is equal to 50.24 ÷ 121 = 0.4152066116 which is rounded to 0.04152 or 41.52% this assumes the dart will always hit the square at least.

Answer:

B) 26

Step-by-step explanation:

Finding PH

Finding GH

If PQ || HI, then the value of GH obtained will be equal to 26. Hence, option B is correct.

The ratio notion is used in mathematics when evaluating two or more numbers. It works as a comparison tool to demonstrate how big or small a particular number is. A ratio divides two quantities in order to compare them.

As per the given figure in the question,

Firstly, we have to find the value of PH.

Take the sides in proportion from the given figure,

GP/PH = GQ/QI

= 10/PH = 15/24

⇒ 10/PH = 5/8

PH = 10/5 x 8

PH = 16

Now, the value of GH will be,

GP + PH

= 10 + 16

= 26
