Allam just finished a great meal at a restaurant in Wisconsin. The sales tax in Wisconsin is 5 percent, and it is costumary to l
lubasha [3.4K]

Answer:

Tax = $0.75

Tip = $2.25

Total (meal + tax + tip)= $18.00

Step-by-step explanation:

When solving for percentages of a number, such as sale tax and tip, multiplying the decimal equivalent of each percentage to the amount will give you the individual costs.  For example, in this case the sales tax is 5%, the decimal equivalent of 5% = 5 ÷ 100 = 0.05.  To find the amount of tax on Allam's meal, multiply the rate by the amount:

0.05 x $15 = $0.75

Since he plans to leave a 15% tip, we can also multiply the amount of the meal by the planned tip amount:

15 ÷ 100 = 0.15

0.15 x $15 = $2.25

Total amount paid, including tax and tip:

$15 + $0.75 + $2.25 = $18.00

WITCHER [35]

Answer:

921.165 feet

Step-by-step explanation:

Ok we are looking for the length of the base.

Now let's take the question and picture it as a triangle, we will find out that it looks like a right angle triangle.

The height= 645 feet

Angle of elevation= 35°

Base is unknown

To find the base

We recall that tan of angle

= opposite/adjacent

In this case

Angle= 35°

Opposite= height= 645

Adjacent= base

Tan 35 = 645/adj

Adj =645/tan 35

Adj =645/0.7002

Adj = 921.165

The base is 921.165 feet
