Answer:
choice A; 128.52 square feet
Step-by-step explanation:
This shape is made up of a semi-circle and a rectangle. The area of the rectangle will be 12*6 = 72 sq ft.
The formula for area of a circle is
*
. also r=radius. We are given the diameter, 12 feet. The radius is diameter/2, so the radius of the circle will be 6 feet.
Since pi is infinite we round it to 3.14.
Plug in the values and our expression will be (3.14*
)/2 because it is a semi-circle. Simplify that to (3.14*36)/2 = 113.04/2 = 56.52 sq ft.
Remember to add the area of the rectangle and semi-circle. 72 + 56.52 = 128.52 sq ft.
Answer:
28
Step-by-step explanation:
Here is the complete question used in answering this question :
Three-fourths of the boats in the marina are white. 4/7 of the remaining boats are blue , and the rest are red . If there are 9red boats, how many boats are in the marina?
We first have to determine the fraction of the boats that are red
1 - (
+
)
1 - 
1 - 
1 - 1
= 9/28
so, 9/28 of the boats are red
let b represent the total number of boats
9/28 x b = 9
to find b, divide both sides of the equation by 28/9
b = 28
Answer:
567.69
Step-by-step explanation:
Let p represent the original price
The Mark up is 27%
= 27/100
= 0.27
= p + 0.27p
= 1.27p
The retail price for pants is
= 1.27(74)
= 93.98
The retail price for suit jacket is
= 1.27(325)
= 412.75
The retail price for dress shirt is
= 1.27(48)
= 60.96
Therefore the markup for a pair of pants, dress shirts and suit jacket can be calculated as follows
= 93.98 + 412.75 + 60.96
= 567.69
8/100, 3/5, 7/10
Explanation:
8/100 = 0.08
3/5 = 0.6
7/10 = 0.7
