A biking track has a length of 0.9 miles . How long is this in feet ?
First fill in the blank on the left side of the equation using one of the ratios. Then write your answer on the right side of the equation.

Answers

0.9 miles converted to feet is 4,752

The biking track of 0.9 miles is 4752 feet long.

Length of the biking track = 0.9miles

What is the relation between mile and foot?

We know that 1 mile equals 5280 feet or the length (in feet) is equal to the miles multiplied by 5,280.

The length of the biking track = 0.9miles

So, The length of the biking track(in feet) = 5280*0.9 feet

The length of the biking track(in feet) = 4752 feet.

Therefore, the biking track of 0.9 miles is 4752 feet long.

Drag and drop an answer choice into each empty box below

The annual interest rate was

4%
8%
16%
40%

Answers

The answer would be 4%

The value of the annual interest rate will be;

⇒ 4%

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division

Given that;

The invested amount = $2000

And , I = 2000 rt ….(i)

Now,

Since, The invested amount = $2000

⇒ Interest ‘I’ = $2160 - $2000

= $160

Time ‘t’ = 2 years

Substituting these values into;

⇒ 160 = (2000 x 2) r

⇒ r = 0.04

⇒ r = 4%

Thus, the interest r = 4%

The representative for the local fishing industry, Rochelle, says that locals are vigorously opposed to Lionels idea. A town meeting is held. Lionel explains how his company is dedicated to practicing the safest drilling techniques. He explains that oil piped from the oceans floor is purer and that it can be harvested in a more efficient way than an oil rig on land. Lionel also emphasizes how much the trucks carrying fish to the markets all over the country would save if local oil was able to be used. Rochelle fires back that in the past, serious accidents with offshore oil drilling have been reported. She points out that if there were a spill, the resulting death of fish would cost the local fisherman their livelihood. Local opinion on the issue is split.
