The diameter of a bicycle wheel is 26 inches How many feet will the bicycle travel if the wheels turn 20 times? Explain how you got your answer.

Answers

Answer 1

Answer:Need to convert mph to rpm. How to do it? See below please.

Explanation:

assume statute mile of 5,280 ft or 1760 yards

(

)

= miles per minute = 0.583333 miles per minute

Now how many ft in 0.58333 miles?

1 mile is 5 280 ft thus

0.58333mile * 5 280 ft/mile = 3 080ft

Circumference of wheel is C=

C = 26*

≈

81.681 inches /12 = 6.807ft/revolution

Now how many times does the wheel rotate in one minute?

080

minute

/ 6.807 ft/revolution = 452.489 rpm

Answer:

157.08cm²

Step-by-step explanation:

pls brainliest

Answer:

157 cm

Explanation:

First you need to find the radius so you divide 20 by 2 (20 ÷ 2). Which will give you, our radius of 10. You take that radius and square it so 10 x 10. You will get a product of 100. Then you multiple the 100 by pi (100 x 3.14) and you will get 314. Since it's a semicircle you need to cut this 314 in half (314 ÷ 2 = 157).

Figure Q was the result of a sequence of transformations on figure P, both shown below.

Which sequence of transformations could take figure P
to figure Q?

A. reflection over the x-axis and translation 7 units
right
B. reflection over the y-axis and translation 3 units
down
C. translation 1 unit right and 180° rotation about the
origin
D. translation 4 units right and 180° rotation about the
origin

Answers

Answer:

Step-by-step explanation:

Because you need to flip it then you move it 7 units

it’s A because and not c or d because Q is a 180 degree rotation from the origin and doesn’t need any translations and B doesn’t align to Q if you follow the transformations so the only applicable answer is A

You made Marcellus 3 times as tall as Dan but you dragged Marcellus’s eyes to be 1 times as far apart as Dan’s eyes. A scale giant would have the same multiple for both.

If Dan's eyes are 5 cm apart, how many centimeters apart should Marcellus's eyes be?

Answers

If you dragged Marcellus’s eyes apart 1x farther than Dan’s eyes then they would both have eyes that are 5cm apart because 5 x 1 = 5

Marcellus's eyes should be 5 cm apart

If Marcellus eyes are 1 times as far apart as Daniels eyes. We can write this mathematically as;

Marcellus eyes are 1x far apart as Dan's eyes.

If we spin this over, we are told that Dan's eyes is 5 cm apart. How far apart would Marcellus's be.

Marcellus eyes will be Dan's eyes divided by the mathematical equivalent we wrote the other time, which is 1 times.

Essentially, Marcellus's eyes will be just as wide as Dan's eyes

(05.01)A scale drawing of a kitchen is shown below. The scale is 1 : 20.

A rectangle is shown. The length of the rectangle is labeled 4 inches. The width of the rectangle is labeled 5 inches.

Show your work to determine the area of the room in square feet.

Answers

Answer:

the room will be 80 inches by 100 inches

( 1 inch ----> 20 inches

so 4 inches ----> 80 inches )

6 2/3 ft by 8 1/3 ft

The area of the given room is 166 2/3 ft².

What is a scale drawing?

A scale drawing is a reduced form in terms of dimensions of an original image / building / object. The scale drawing is usually reduced at a constant dimension.

The area of the room can be calculated as;

The length of the room = 20 x 4 = 80 inches

The width of the room = 20 x 5 = 100 inches.

Now, 1 inch = 1/12 foot

80 inches / 12 = 6 2/3 ft

100 / 12 = 8 1/3 ft

The Area = 6 2/3 x 8 1/3

The Area = 25/3 x 20/3

The Area = 500 / 3

The Area = 166 2/3 ft²

Therefore, The area of the given room is 166 2/3 ft².

Find the value of the missing angle ``

180

50

90

Answers

Answer:50

Step-by-step explanation:

a right angle is always 90 degrees and we know triangles add to 180 degrees. So add 90 and 40 to get 130. Then subtract 180 from 130 to get 50.

50 because there can only be 1- 90 degrees angle in a triangle. A 180 angle is a strait line. You can go through a process of elimination
