Use scientific notation to estimate the number of inches in 1,225 miles. Include all calculations in your final answer.

valentinak56 [21]

Answer:

1,225 miles = 77616000 inches

Step-by-step explanation:

It is asked to find the number of inches in 1,225 miles

Given

1 inch ≈ 1.578 × 10^-5 miles

Therefore, 1 mile = 63360 inches

Therefore, 1,225 miles = 1225 x 63360 inches

1,225 miles = 77616000 inches

or 1,225 miles = 7.7 x $10^{7}$ inches

Therefore the final answer is

1,225 miles = 77616000 inches

or 1,225 miles = 7.7 x $10^{7}$ inches

PlEase explain where the decimal and zero comes in for 4840/90?

Anika [276]

Answer:

Read my explanation

Step-by-step explanation:

Since they both end with a 0, you can just cancel it out. So you'd have 484/9.

The answer to that is 53.7777777777...

So the decimal would come before the 3 and after the 7.

I hope this helped and have a good rest of your day!

if it asks for scale factor does that mean i’m supposed to write a ratio? Can someone solve and explain these for me i’m so conf

STatiana [176]

Yes scale factor means ratio. The height of the smaller pyramid to the larger pyramid in ratio form is 8:24 which simplifies to 1:3. The ratio of its areas is the scale factor squared, so 1^2:3^2=1:9. Since the surface area of the smaller pyramid is 124, the surface area of the larger pyramid must be 124x9. The ratio of volumes is the scale factor cubed, so 1^3:3^3=1:27. If the volume of the larger pyramid is 648, then the volume of the smaller pyramid is 1/27 of that, which equals 24.
