the earth rotates about its axis once every 23 h 56 min 4 s, and the radius of the earth is 3960 mile. find the linear speed of a point on the equator in mi/h

Answers

Answer 1

Answer: $23h\ 56min\ 4s=\left(23+(56)/(60)+(4)/(3600)\right)h=\left((82800)/(3600)+(3360)/(3600)+(4)/(3600)\right)h\n\n=(86164)/(3600)h\approx23.93h\n\nL=2\pi R;\ R=3960mi\to L=2\pi\cdot3960mi=7920\pi mi\approx7920\cdot3.14mi\n\n=24868.8mi\n\nv=(24868.8)/(23.93)\ mi/h\approx1039.231\ mi/h\leftarrow answer$

The perimeter of rectangle Z is equal to its area. Rectangle Y has the same perimeter as rectangle Z. The length of rectangle Y is 5 inches and the width is 3 inches. Explain how you can find length and width of rectangle Z.

Answers

The length and width of rectangle Z would be 4 inches as the width and 4 inches as the length. This is because first, you combine and find the total perimeter of Rectangle Y. The perimeter of rectangle y would be P=length + length + width + width, which is 16 inches. Rectangle Z has the same perimeter total as rectangle Y and rectangle Zs area is the same as rectangle Y. 4x4 is equal to 16 while to find the perimeter, 4+4+4+4 is also 16.

Olivia has 1 1/5 yards of fabric. she uses 5/8 of the fabric to make a shirt. How much fabric did she use?

Answers

what you do is add 11/5 and 5/8 so you will line those up and find out the common denominator which is 40 cause 5×8 is 40 so you put 40 for your denominator. next you figure out the numerator which will be 88 and 25 now since were adding your gonna take that 88 + 25 and you get 113/40 now you do 40÷113 and you get 17 and 33/40.

Make 1 1/5 into improper fraction which is 6/5 and then find the common denominator 6/5 and 5/8.
Common denominator is 40. Multiply 8 by 6 and 8 by 5 so it would become 48/40. Do the same with 5/8 except multiply by 5 which would be 25/40. Subtract 48/40 and 25/40 which is.....

Write 6.25 as a fraction

Answers

6.25 is equivalent to 6 and 1/4. To find the compound fraction, multiply 4, present in the denominator, and 6. Then add 1, present in the numerator. The answer should be over four. So: 4*6=24, 24+1=25, 25/4= 6.25

In 2013, the population of the state of New York was approximately 19.65 million, and the population of New York City was 8,406,000. In 2013, how many people in New York state did not live in New York City? The answer in standard notation is The answer in scientific notation is p × 10q, where p is
and q is

Answers

Population of the state of New York is 19.65 million.
Million is equal to 1*10^6
So 19.65*10^6

Population of New York city is 8,406,000.
It is equal to 8.406*10^6

Therefore people in New York state did not in New York city is,
19.65*10^6 - 8.406*10^6
11.244*10^6
1.1244*10^7

The answer in standard notation is 11244000 . The answer in scientific notation is p × 10q, where p is 1.1244 and q is 7 .
