bellamy is building a gate to put on a fence. the gates measurements are 7 feet by 7 feet a diagonal wooden brace is going to be
Rama09 [41]

The length of the diagonal is the hypotenuse of the fence

The length of the wood is 7\sqrt{ 2 yards

<h3>How to determine the length of the wood?</h3>

The dimensions of the fence are:

7 ft by 7 ft

The length (L) of the diagonal is calculated using:

L = \sqrt{a^2 + b^2

This gives

L = \sqrt{7^2 + 7^2

Express as products

L = \sqrt{7^2 * 2

Express as radical

L = 7\sqrt{ 2

Hence, the length of the wood is 7\sqrt{ 2 yards

HELP PLZ.....I NEED THIS....One wheel of a bicycle has 24-inch diameter. About how many feet will the bicycle travel when the wh
Ne4ueva [31]
First, find the circumference of the wheel using C=2 \pi r

You know that your diameter is 24. To find the radius, divide the diameter by 2, which is 12.

Input 12 as r and simplify. ->  C=2 \pi (12)
C=24 \pi

estimate your Pi as 3.14
C=24(3.14)

and multiply. C=75.36

Now you know the distance of one full revolution in inches. To find 200 revolutions, multiply that answer by 200.

75.36 * 200 = 15,072 inches

But because this is in inches, you have to find the answer in feet, so just divide that answer by 12.

15,072 / 12 = 1,256 ft

Zarrin [17]

By using division, it can be calculated that

Jeremy can row 1 mile in 4 hours

What is division?

Division is the process by which value of single unit can be calculated from the value of multiple unit.

The number to be divided is known as dividend, the number by which the dividend is divided is the divisor, the result obtained is the quotient and the remaining part is the remainder.

There is a well known formula for division

Divisor x Quotient + Remainder = Dividend.

This is a word problem on division

Jeremy can row 3 miles in 12 hours

Jeremy can row 1 mile in 12 \div 3 = 4 hours
