I need someone to do this question

Answer:

$1487.50

Step-by-step explanation:

The amount of interest due is ...

I = Prt

where P is the loan amount, r is the annual rate, and t is the number of years. Here, t = 6 months = 1/2 year, so the interest due is ...

I = $1400×0.125×1/2 = $87.50

The total amount due is the sum of the loan amount and the interest:

due = $1400 +87.50 = $1487.50

The total amount due after 60 months is $1487.50.

Saturn's rings extend to about 120,000 kilometers above Saturn's equator. Saturn's diameter at its equator is also about 120,000

Allisa [31]

Answer:

1130400 km

Step-by-step explanation:

We know the formula for circumference of a circle:

Circumference = $2\pi r$

So we need the radius of Saturn ring to calculate its circumference.

We are given Saturn's diamter which is 120,000km; and know that Saturn's ring extends for about 120,000 km from the circumference of the Saturn.

Therefore, the radius of Saturn's ring will be 120000 km plus half of the diameter of Saturn:

Radius of Saturn's ring = 120000 + (120000/2) = 180000 km

Circumference of Saturn's rings = 2 x 3.14 x 180000 = 1130400 km

Write “252 miles per 8 gallons” as a rate in simplest form.

Nina [5.8K]

Okay so since we have to put 252 miles per 8 gallons into the simplest form I'm going to say that we divide 252/8=31.5 so we should have 31.5 miles per gallon as our answer
