Answers

Answer 1

Answer:

The length of each side of the square is 5ft

Area of a composite function

Area of the composite figure = area of square + area of a triangle

Substitute the given information

32.5 = Area of square + 7.5

Area of square = 32.5 - 7.5

Area of squar = 25.0 ft^2

Since Area of square = L^2

L = 5ft

Hence the length of each side of the square is 5ft

How many cubes with the side lengths of 1/2 cm does it take to fill the prisim?

Answers

Answer:

Number of cubes that fills the prism=24

Step-by-step explanation:

The number of cube that completely fill the prism=Volume of Prism/Volume of cube with side 1/2 cm=0.5 cm

Volume of the prism= $Length*Width*Height$

$Length=2 cm\n\n Width=1 cm\n \n Height=3/2 cm = 1.5 cm$

Volume of Prism = $2*1*1.5$

$=3.0 cm^3$

Volume of the Cube:

$Side*Side*Side\n\n=0.5*0.5*0.5$

$= 0.125 cm^3$

Number of cubes that fills the prism:

$3.0/0.125\n\n=24 cubes$

So, the number of cubes that can fill the prism is '24'

The world record for the longest journey driven by car is 626,960 km. The longest journey by tractor is 21,199 km. Round each number to the nearest ten thousand to find the answer.

What is the approximate difference between the two journeys? pLEASE HELP GIVING ALL MY POINTS TO THE FIRST PERSON WHO DOES.

Answers

The answer is 605,761 because when it says difference you must subtract.

If you round both numbers to ten thousand car would be 630,000 and tractor would be 20,000. Approximate means estimate and not exact.
630,000-20,000=610,000
The approximate distance is 610,000.
Miles= 379,036
