Answer:
Option A is the correct answer.
Explanation:
Let A be the base area and h be the height of prism.
Volume of prism = Base area x Height = a x h =ah
Now we have base area of pyramid = Base area of prism = a ( both have same type of base)
Height of pyramid = 3 x height of prism = 3h
Volume of pyramid = 1/3 x Base area x Height = 1/3 x a x 3h = ah
Comparing both volumes, we will get Volume of prism = Volume of pyramid
So their ratio is 1.
Option A is the correct answer.
Step-by-step explanation:
-3x - 7y = -63
-(3x + 7y) = -63
3x + 7y = -63/-1
3x + 7y = 63
Value of x
3x + 7y = 63
3x = 63 - 7y
x = (63 - 7y)/3
Value of y
3x + 7y = 63
7y = 63 - 3x
y = (63 - 3x)/7

Answer: s(s+4)=7, 7 shelves
Step-by-step explanation:
I think it's easiest to find these type of answers by finding the common factors of a number. First 77, they are 1×77 & 7×11.so you can have 11 rocks on 7 shelves or 7 rocks on 11 shelves. The question states the number or rocks on the shelf is more than the number of shelves, so you must have 11 rocks on 7 shelves. You know you have 77 rocks, so the equation must equal 77. I plugged 7 in for s in the equations to determine the correct answer. 7(7+4)=77.
