Answer:
252 inches
Step-by-step explanation:
Step 1:finding the area of triangle
b*h*1/2=3*4*1/2 but since there are two right angles in a triangular prism because of the two sides then its just 3*4 which is 12.
Step 2:finding the perimeter of the right angle
so 3,4 and 5 are known to be part of the right angle sp that means 3+4+5=12
Step 3:multiplying the height and perimeter of the triangular prism
20*12=240
Step 4;(A.K.A the final step)Adding the remaining numbers together.
240+12=252 inches
Answer:
3/8
Step-by-step explanation:
After spending 3/8 of her money on a bag, she has 5/8 of the original amount of money left. As she gave 2/5 of the remaining amount of money to her sister, she gave 1/4 of the original amount of money to her sister (5/8 × 2/5 = 1/4). Therefore, there's only 3/8 (1 - 3/8 - 1/4 = 3/8) of the original amount of money left in her bag.
Or, is it asking you to subtract the? In that case
5/4 - 3/8 = 7/8
Answer:
what's x?
Step-by-step explanation:
substitute whatever you have for x in the equation. I was taught f(x) is no different from y=.
