I am not 100% positive but from what I remember learning I think the answer you are looking for on the first question is C.

If it is question number 1 then the answer is B. Many men that worked in factories were drafted for war. Women soon had to take the places of their husbands in factories. Due to the insufficient amount of people at the factories the had to shutdown. Soon families weren't able to make the money they needed to survive. This created a lot of debt for American families.

A car traveling with constant speed travels 150 km in 7200s what is the speed
Allisa [31]
We want the seconds to be converted in hours to work out the speed, so:

7200Seconds /60 / 60 =2 Hours
150 / 2 = 75

Therefore the car travels at 75kmh.

One large bubble separates into four small bubbles so that the total area of the small bubbles is equal to the area of the large
Travka [436]

find area of 1 small bubble

πr² = π × 5²

= 78.54

total area of 4 small bubble

78.54 × 4 = 314.16

total area of 4 small bubble = area of big bubble

= 314.16

find it's radius

πr² = 314.16

r² = 314.16 ÷ π

r² = 100

r = √100

r = 10

What is the distance in miles, between Joe's home and the park? Round answers to the nearest tenth
Svetlanka [38]
You're on the right track! Now that you have drawn a right triangle with the hypotenuse as the segment from Joe's home to the Park, we can use Pythagorean Theorem to solve for the hypotenuse. 

Pythagorean Theorem = a squared + b squared = c squared
A and B are the legs, and C is the hypotenuse. We can find the legs be calculating how many units they are. 

2 - (-1) = 3
3 - 1 = 2

Pythagorean Theorem = 3 squared + 2 squared = c squared
= 9 + 4 = c squared
= 13 = c squared
= \sqrt{13} = c

The square root of 13 is around 3.6, so Joe's house is approximately 3.6 miles away from the park.
