How far does the unicycle move if the wheel turns once?

Mathematics
1 answer:
algol [13]3 years ago
8 0

The unicycle moves a distance of 251.20cm if the wheel turn once and the wheel must rotate 32 times to cover a distance of 100m

<h3>Circumference of a circle</h3>

The formula for calculating the circumference of a circle is given as:

C = 2pi r

r is the radius of the circle

a) r = 80/2 = 40cm

C = 2(3.14)(40)
C = 251.20 cm

Hence the unicycle moves a distance of 251.20cm if the wheel turn once

b) Number of revolution * 2pi r = distance covered

n * 2(3.14)(50) = 10000
314n = 10000
n = 10000/314

n =32

Hence the wheel must rotate 32 times to cover a distance of 100m

iragen [17]

<u>Answer-</u>

<em>Cooper will receive </em><em>$12.00</em><em> at the end of the month.</em>

<u>Solution-</u>

Cooper has $1500 in the account now and he deposits an additional $500 at the beginning of the month.

So the total principal becomes 1500+500 = $2000

Given here,

APR = annual percentage rate = 7.2%

But as we have to calculate the monthly interest, so monthly interest rate would be =\dfrac{7.2}{12}=0.6\%

Time period = 1 month

So, the interest after 1 month will be,

\text{interest}=\dfrac{\text{Principal}\times \text{Rate of interest}\times \text{Time period}}{100}

=\dfrac{2000\times 0.6\times 1}{100}

=\$12.00

Therefore, Cooper will receive $12.00 at the end of the month.

PLEASE HELP 20 POINTS PLEASE GIVE EXPLANTION ​
Georgia [21]

Answer:

300 in³

Step-by-step explanation:

To calculate the volume of a composite solid, simply split it into smaller solids and calculate their separate volumes. The volumes of each of the individual solids are then added together to give the total volume of the composite solid.

Remember, the formula for volume is: l • w • h

12(length) x 5 (width) = 60 x 3(height) = 180 in

5(width) x 8(length) = 40 x 3(height) = 120 in

Now, finally we add up the answers.

180 + 120 = 300 in³

(*Don't forget to cube³ your answer since it's Volume)

Answer:

13. -2

14. 0

15. 2

16. 0

Step-by-step explanation:

Since the function is originally f(x), you go to wherever the x value is and see what the y value is.

So...

f(2) means go to x = 2 and see that y = -2

A line has the points (3,7), (4,9), (5,11) and (6,13). If the slope of the line is divided by 2, what is the new slope?
qwelly [4]

Answer:

1

Step-by-step explanation:

1) first, we need to calculate slope of old line:

Let’s take coordinate points (3,7) and (4,9)

3-x1

7-y1

4-x2

9-y2

Slope formula: (y2-y1)/(x2-x1)

Let’s plug in our values:

(9-7)/(4-3)

2/1

Old slope=2

So we need to divide 2 with 2

2/2=1

New slope=1

Hope this helps
