If Ben bikes 3 miles and then bikes 1,000 yards back toward his starting point, how many yards is Ben from his starting point?

Answers

First lets convert the 3 miles to yards. 3 miles is equal to about 5280 yards . So now we have to subtract 5280 yards by 1,000 which is equal to 4,280.
So the final answer is 4,280.
To answer this we will first convert d 3 miles to yards. den we will subtract the 1,000 yards and d answer will be d amount of yards Ben is from his starting point. lets do it:-

1 mile = 1760 yards

Now lets multiple:-

1760 × 3 = 5280
3 miles = 5280 yards

lets subtract now:-

5280 - 1000 = 4280

So, Ben is 4,280 yards far from his starting point.

The area of a rectangle is 128 sq. ft. If the width is twice the length, what is the measure of the length of the rectangle?

Answers

Length is 8 and width is 16. I hope this helps!
We calculate the area of ​​a rectangle with the equation

A = LW*1/2
A = 
The area of a rectangle
L = 
the height of the triangle
W = the base of the triangle

If the equation is one unknown to solve them quickly .
A = 128sq.ft
L = ?
W = 2L

substitute values ​​into the formula

A = L * W *1/2
128sq.ft = Lft. * (2Lft) *1/2
128 = L
²
L = √128 = 8√2

W = 2L = 2*8
√2 = 16√2





Can u please answer the question

Answers

Ok it is said that it is almost 15%
So we know how to round:
if it the rounding place value is 5 or more, we round upwards
If it is less than 5, it stays the same

So in this example:
The percentage is rounded up to the nearest whole number:
Look at the number after the decimal point.

14.1% ⇒ is closer to 14%
15.1% ⇒ is closer to 15%
15.8% ⇒ is closer to 16%
14.2% ⇒ is closer to 14%
14.3% ⇒ is closer to 14%
15.5% ⇒ is closer to 16%
14.4% ⇒ is closer to 14%
15.6% ⇒ is closer to 16%
14.5% ⇒ is closer to 15%
15.7% ⇒ is closer to 16%
14.6% ⇒ is closer to 15%
15.3% ⇒ is closer to 15%
14.7% ⇒ is closer to 15%
15.9% ⇒ is closer to 16%
14.8% ⇒ is closer to 15%
15.2% ⇒ is closer to 15%
14.9% ⇒ is closer to 15%
15.4% ⇒ is closer to 15%

These are the values that the percentage could have been to one decimal place:
15.1%, 14.5%, 14.6%, 15.3%, 14.7%, 14.8%, 15.2%, 14.9%, and 15.4%
