You need to use Pythagoras’ Theorem. 
A² + B² = c² and c is the hypotenuse of the right angled triangle.

The height of the tower (5 feet) is A and the distance from the end of the cable and the base of the tower (12 feet) is B. The length of ONE cable is c. So:

A² + B² = c²
5² + 12² = c²
25 + 144 = c²
169 = c²
13 = c. This is the length of one cable.

3 x 13 = 39 therefore the total length of the cables is 39 feet.

Two types of barrel units were in use in the 1920s in the united states. the apple barrel had a legally set volume of 7056 cubic
r-ruslan [8.4K]
1.) 7,056 * 41 = 289,296 (apple barrel volume * no. of barrels sold)
     5,826 * 41 = 238,866 (cranberry barrel volume * no. of barrels sold)

2.) Subtract cranberry barrel volume from apple barrel volume
    289,296 - 238,866 = 50,430 cubic inches

3.) Convert 50,430 cubic inches to liters
     50,430 = 826.39 liters or 826.40 liters (rounded off)

4.) Therefore, 826.40 liters is the discrepancy in the shipment volume.

your family went out to dinner to celebrate your grandmas 100th birthday. The total for the dinner was $208.60, so your parents
Allushta [10]

Answer:

\%Tip = 13.04\%

Step-by-step explanation:

Given

Tip= \$31.29

Bill = \$208.60

Required

Determine the percentage of the tip

First, we calculate the amount paid

Amount = Tip + Bill

Amount = \$31.29 + \$208.60

Amount = \$239.89

The percentage of the tip is then calculated using:

\%Tip = \frac{Tip}{Amount} * 100\%

\%Tip = \frac{31.29}{239.89} * 100\%

\%Tip = \frac{31.29* 100}{239.89} \%

\%Tip = \frac{3129}{239.89} \%

\%Tip = 13.04\%
