HELP IM LITERALLY FAILING MATH!!!

Answers

Answer:

1.4 ft

Step-by-step explanation:

Ok so first off you want to take the area(1.96) and divide it by your height(1.4)

This will get you B!(1.4)

Also since this is a square all the sides are equal!

Answer: b= 1.4

Step-by-step explanation:

Area = length x width

1.96 = “b” x 1.4

Since we have the area and one side of the box, we can rearrange the equation to find the missing side.

Since 1.4 is being multiplied on the right side of the equation, we must divide by 1.4 to remove it. Divide both sides by 1.4

1.96/1.4= b

b= 1.4

The residence of a city voted on whether to raise property taxes the ratio of yes votes to no votes was 7 to 4 if there were 3672 no votes what was the total number of votes

Answers

Answer: 10,098 votes

Step-by-step explanation:

The ratio is 7 : 4 which means that for every 7 yes votes, there were 4 no votes.

To find the total votes, add the ratios:

= 7 + 4

= 11

4/11 are the no votes out of the total. Assuming the total is x, the formula is:

4/11x = 3,672

x = 3,672 / 4/11

x = 10,098 votes
