The fuel tank in Mr. Swenson’s car holds 16.5 gallons of fuel.The car consumes 1 gallon of fuel for each 24.3 miles driven.
Mr. Swenson started a trip of 250 miles with a full tank of fuel.
Abouthow much fuel remained at the end of the trip?

Answers

Given:
Fuel tank : 16.5 gallons of fuel
1 gallon = 24.3 miles
250 miles traveled

250 miles / 24.3 miles = 10.29 
10.29 * 1 gallon = 10.29 gallons

16.5 gallons - 10.29 gallons = 6.21 gallons of fuel remaining. 

16.5 gallons * 24.3 miles = 400.95 miles
400.95 miles - 250 miles = 150.95 miles
150.95 miles / 24.3 miles = 6.21 gallons of fuel remaining

A plane is approaching an aircraft carrier at 25° angle of elevation from 3.2 miles away how far above sea level is the plane

Answers

Answer:

Height\approx 1.35\ miles

Step-by-step explanation:

The angle of elevation=25\textdegree

It is 3.2\ miles away from the point.

If we imagine a right  triangle having an angle 25\textdegree.

Hypotenuse=3.2, Opposite=Height from sea level(h)

\sin 25=(opposite)/(hypotenuse)\n\n\sin 25=(h)/(3.2)\n\nh=3.2* \sin 25\n\nh=3.2* 0.4226\n\nh=1.3524\approx 1.35\ miles

What is 7,491,001 rounded to the nearest hundrer thousand

Answers

Answer:

7,491,001 --> 7,500,000

Step-by-step explanation:

This is because rounding happens like this:

The rounding rule is: 5 and above rounds up, and 4 and under rounds down.

Here is a little rhyme for the rule: 5 and above rounds up like a dove. 4 and below, get down low!

7,491,001

--> you want to round the underlined digit. You round using the next digit to the right. The next digit over is the 9. Remember our rounding rule. Since 9 is above 5, the 4 would round up. Note - the digits after the rounded number always become zeros, even if you round up or down. So our new number is 7,500,000.

I hope I helped!
