V= 4/3 π R^3
17 x 17 x 17 = 4913 x 4 = 19652 / 3 = 6550.66667
or 6550.7
6550.7 x 3.14 = <span>20569.198

Answer:
$63.06
Step-by-step explanation:
<em>Total Cost </em>
First, find the total cost for everything she bought
3 lamps at 23.59 each, and a sofa for 769.99
<u>Lamps </u>
Add 23.59 3 times, or multiply 3 times 23.59
23.59+23.59+23.59=70.77
23.59*3=70.77
<u>Total </u>
Add the lamps cost to the sofa cost
70.77+769.99=840.76
Sales Tax
Multiply the sales tax rate by her total cost
840.76 *7.5%
Convert 7.5% to a decimal by dividing by 100, or moving the decimal place 2 spots to the left
7.5/100=0.075
7.5--> .75-->0.075
840.76* 0.075=63.057
Round to the nearest cent, or hundreth: 63.06
The sales tax is: $63.06
Answer:
Hank is correct
Step-by-step explanation:
With parallel lines intersected by the same line, all corresponding angles are equal. Also remember that the two angles the are formed on each line need to add to 180 degrees. So we can take the two given angle: 7x+10 and x + 10 and add them. x + 10 + 7x + 10 = 8x + 20 = 180
So Hank has the correct equation.
Consider two adjacent rectangular rooms having Length=L, and, Breadth = B
Now Suppose the wall which is in between two rooms has a height or length =H.
Breadth of wall = B [ if the wall doesn't exceed the breadth of room]
Considering two rooms to be identical,
Area of each room= L × B square unit
Area of each tile = 1×1=1 square unit
Number of tiles required= L B ÷ 1= LB tiles( product of length and breadth of room is number of tiles required)
Suppose if,LB= N
B= N/L .................(1)
Area of wall(W) = B×H= B H square unit
B =W/H ......................(2)
Equating (1) and (2)
⇒N/L = W/ H
⇒H =w-z/N
⇒H =WL/LH
⇒H = W/B
⇒ H =area of wall / Breadth of room and wall
