Calculate the area of the regular pentagon below:
Answer: 858.55 in
Step-by-step explanation: You calculate the area of the triangle ( 22.3 x 15.4/2), then you multiply the result by 5.
Answer:
858.55
Step-by-step explanation:
Area of triangle = 1/2BH
1/2(22.3*15.4) = 171.71
Because there is five sides on the pentagon we have to multiply the 172.71 by 5 to get the final answer.
171.1(5) = 858.55

In 56 years, Kevin will be 9 times as old as he is now
How old is Kevin now?
Answer:
correct answer is 7 years
Step-by-step explanation:
A+56=9(A)
56+9A
A=7
he will be 7 years old he is pretty old
Answer:
Kevin is 7 years old right now.
Step-by-step explanation:
Let x be Kevin's age right now, that's what we're trying to find.
In 56 years, he'll be 9 times older than he is now, so we can say:
x + 56 = 9x
Now we can get the x values on the right side of the equation so that:
56 = 8x
Now solve for x and you have his current age which is 7.

Answer:
Area of five squares = 1289.09 square units
Perimeter = 194.6 units
Step-by-step explanation:
Area of square and perimeter:
First find the length of each square, then find the area of each square.
To find the area of five squares, add all the area of each square.
Side of square1 = 27 units
\(\sf Side \ of \ square2 = \dfrac{2}{3}*27=2*9 = 18 \ units\\\\Side \ of\ square3= \dfrac{2}{3}*18=2*6=12 \ units\\\\Side \ of \ square4=\dfrac{2}{3}*12=2*4=8 \ units\\\\Side \ of \ square5=\dfrac{2}{3}*8=\dfrac{16}{3}=5.3 \ units\)
Area of square1 = 27*27 = 729 square units
Area of square2 = 18*18 = 324 square units
Area of square3 = 12*12 = 144 square units
Area of square4 = 8*8 = 64 square units
Area of square5 = 5.3*5.3 = 28.09 square units
Area of five squares = 729 + 324 + 144 + 64 +28.09
= 1289.09 square units
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Perimeter of the composite figure = (27 + 27+27+9) + (18+18+6) +(12+12+4) + (8+8+2.7)+ (5.3+5.3+5.3)
= 90 + 42 + 28 + 18.7 + 15.9
= 194.6 units

Determine which recipe has a greater ratio of water to dish soap and plot the three ordered pairs for that recipe on the graph.
The recipe that has the greater ratio of water to dish soap is Recipe A
The graph of Recipe A created with MS Excel is attached.
What is a ratio?A ratio is a representation of the comparison of two quantities, using division.
The data in the tables indicates that we get;
Recipe A
Ratio of water to dish soap = 10 : 4 = 5 : 2
Recipe B
Ratio of water to dish soap = 12 : 6 = 2 : 1
The ratio 5 : 2 for the water to dish soap of Recipe A is larger than the ratio 2 : 1 for the water to dish soap of Recipe B. Therefore;
Recipe A has a greater ratio of water to dish soap

Answer: C
Step-by-step explanation:
First set greater than 300 since Zack has to make more than 300 to make a profit. The equation is the amount he makes (n) - cost of supplies ($32.50). He is completing 4 rooms so multiply (n - 32.5) with 4.
The equation would be 4 (n - 32.5)>300
Now to solve for n, divide 4 on other sides, then add 32.5 to both sides.
