Answer:
$39
Step-by-step explanation:
To calculate the total cost of his meal, add the subtotal ($30), the tax on subtotal ($30 X 10%) and the tip ($30 X 20%).
Convert all percentages to decimals to multiply.
Finding tax:
10% = 0.1
Tax = $30 X 0.1 = $3
Finding tip:
20% = 0.2
Tip = $30 X 0.2 = $6
Subtotal + Tax + Tip
= $30 + $3 + $6
= $39
The total cost of his meal was $39.

Shana ran 18 miles in a month
Step-by-step explanation:
Shana ran 6 miles in one week. This was 1/3 of what she ran in a month
Let x be the miles she ran in a month
1/3 one third of miles she ran in a month is 6 miles
Now we solve for x
To solve for x , we multiply 3 on both sides
1x= 18
so x= 18
So Shana ran 18 miles in a month
The height of the cone 4 inches.
Step-by-step explanation:
Given,
Volume of cylinder and cone is same.
For cylinder
Radius (r) = 2 inches
Height (h) = 3 inches
For cone
Radius (r) = 3 inches
To find the height of cone say H
Formula:
Volume of cylinder = π
Volume of cone = π
According to the problem,
π = π
or, H =
or, H = 4
Hence,
The height of the cone 4 inches.
