What is 5,254,071,926 written in standard form

Elis [28]

5.254071926×10^9
Standard form is taking a large number and putting it in a form where the number is smaller than 10. To do that (using the number above) you would take the first number which is 5 and then make every number after it part of a decimal. You then use [×10^x] (multiplied by 10 to the power of the amount of numbers after the decimal point (In this case 9)) to show others that to find the full number you multiply the decimal by 10 to the power of 9.

When Amy roller-skates, she moves 110 yards per minute. What is her speed in miles per hour? Round your answer to the nearest hu

Softa [21]

Answer:

Speed of Amy is 3.75 miles per hour.

Step-by-step explanation:

We have, speed of Amy = 110 yards per minute

This means, she covers 110 yards of distance in 1 minute.

Now, to convert the speed of Amy into miles per hour, we will first convert the distance from yards into miles and then convert time from minutes to hour.

We know that,

1 yard = 3 feet

∴ 110 yards = 3 × 110 feet = 330 feet

Now, we also know that,

5280 feet = 1 mile

∴ 1 feet = $\frac{1}{5280}$ miles
