Answer:
2) 360 square inches
Step-by-step explanation:
First of all we have to verify that the base triangle is a right triangle
For this we use Pythagoras
h² = l1² + l2²
13² = 12² + 5²
169 = 144 + 25
169 = 169
Equality is fulfilled by what is a right triangle
Now we need to calculate the area of the triangle
a = (12 in * 5 in) / 2
a = 60in² / 2
a = 30in²
Now we have to calculate the 3 areas of the rectangles
a1 = 10in * 13 in
a1 = 130in²
a2 = 10 in * 12 in
a2 = 120in²
a3 = 10 in * 5 in
a3 = 50in²
Now we must add all the calculated areas and the triangle 2 times
a1 + a2 + a3 + 2a =
130in² + 120in² + 50in² + 2 * 30in²
360in²
The surface area of the prism is 360in²
Time-and-a-half doesn't make enough sense to answer the question. If you fix it, or comment below the correction I will gladly help.
Answer:
Each step is 30 inches
Step-by-step explanation: One yard is 36 inches. 10 yards is 360 inches.
360 divided by 12 is 30.
75x+2=
75x-2=-2. move the 2 to the other side
75x=-2 now divide 75 both sides
75/75x=-2/75
x=-2/75
Answer:
$260
Step-by-step explanation:
0.06 x 200 = 12
12 x 5 = 60
200 + 60 = 260
