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

A circular lawn with a diameter of 20 square feet will be planted with grass seed. How many square feet are on the lawn?

31.4 ft squared

Answers

Answer:

314 ft squared

Step-by-step explanation:

A = πr^2 = π · 102 ≈ 314.15927

Answer:

314.159265359 ft squared or 314.16 ft squared rounded to the hundredths place. The closest result is option C.

Step-by-step explanation:

The formula for finding the area of a circle is A=π×r^2.

Step 1: Find the radius which is half of the diameter. In this case, the radius is 10 feet.

Step 2: Square the radius that you found. In this case, the number will be 100ft or 10^2.

Step 3: Multiple this number by π, or 3.14 if your teacher allows it. So in this case, 100×π=314.159265359 or 314.16 rounded to the hundredths place. If you use 3.14... the answer is 314.

Step 4: You've got your answer. Hope this helps!

Barb purchased a loaf of bread for $2 and p pounds of sliced gam at $5 per pound for a total of 13.25. The relationship between what she purchased and her total purchase price is represented by the equation 5p + 2 = 13.25. What was the total number of pounds of ham that Barb purchased?

Answers

The answer is 2.25 because the total was 13.25 and it is asking you how much he paid for the ham. So you would first subtract 2 from 13.25 which gives you 11.25 and then divide by 5 and it will give you the answer which is 2.25

An art teacher makes a batch of purple paint by mixing 3/4 cup red paint with 3/4 cup of blue paint. If she mikes 13 batches, how many cups of purple paint will she have?

Answers

She will have 19.5 cups of purple paint.
I couldn’t write the explanation of how you get the answer, but look your question up on Brainly and it’ll give you your explanation.

Hope this helped! :)

Answer:

She will have 19 ¹/₂ batches of purple paint

Step-by-step explanation:

r + b = 1 bp

³/₄ r + ³/₄ b = 1 bp

(³/₄ + ³/₄) * 13 = x bp

⁶/₄ = 1 ¹/₂

1 ¹/₂ * 13 = 13 ¹³/₂ = 19 ¹/₂ batches

VARIABLE KEY:

r = red

b = blue

bp = batches of purple

x = total number of bp

I need help with this question.

Answers

Answer:

$367.38 is the cost to stain the entire deck.

Step-by-step explanation:

Here is what you need to know beforehand:

Diameter is a line that goes through a circle. Radius is a line that goes from the edge of the circle all the way to the center/a line that goes halfway through the circle.

--------------------------------------------------------------------------------------------------------------

First, find the area of the circle. Here is the formula:

Area = 3.14 (Pi) x r²

Since radius is half of the diameter (as explained above), you'll need to divide the diameter in half: 12m/2 = 6m

So the formula will look like this:

Area = 3.14 x 6²

Then, you just do the math:

Area = 3.14 x 6²

Area = 3.14 x 36

Area = 113.04

The goal of the problem is to find the amount of money Emma needs. Finally, all you need to do is multiply the amount it cost to stain per square meter by the total area of the deck:

Answer = 113.04 x 3.25

Answer = 367.38

$367.38 is the cost to stain the entire deck.
