The figures are similar. Place each rectangle's sides as fraction, and make them equal to each other
18/27 = 6/x
cross multiply
18(x) = 6(27)
Multiply
18x = 162
Isolate the x. Divide by 18
18x/18 = 162/18
x = 9
To calculate the area, multiply 9 with 6
9 x 6 = 54
(A) 54 is your answer

1 inch = 15 feet
1/4(15) = 3.75 in.
1/3(15) = 5
The actual dimensions are B) 3.75 ft by 5 ft

hope this helps
the surface area should be 544 (whatever the unit is)
Step-by-step explanation:
You start by taking the rectangles on the side and finding their area.
1. (10×14)×2 ←Because there are two rectanglular sides.
2. find the area of the triangles on the side. 1/2bh = area of triangle.
(.5×8×6)×4 ← in order to find the area for all of the triangles.
3. lastly take the base of the prism and find the area then add the previously found values together.
(12×14)+(.5×8×6)×4+ (10×14)×2 = 544
Answer:
40,000
Step-by-step explanation:120,000 divided by 30% is 40,00 because 120,000 divide by 30 is 40,000
Ages of Dan and Cary are 29 and 33 respectively.
<u>Step-by-step explanation:</u>
Step 1:
Form equations out of the given details. Let the age of Dan be x, then age of Cary is x + 4.
In 7 years, sum of their ages = 76
⇒ (x + 7) + (x + 4 + 7) = 76
⇒ 2x + 18 = 76
⇒ 2x = 58
⇒ x = 29
Step 2:
Calculate age of Cary.
⇒ x + 4 = 33
