Answer:
8.5 in
Step-by-step explanation:
You are solving for the hypotenuse right? So you would use this formula:
c = square root a^2+b^2
the c is the hypotenuse (long side of a right triangle) and a will be 4 and b will be 7.5. substitute the numbers in, solve, and you get 8.5 inches!
x = square root 4^2 + 7.5^2
x = square root 16 + 56.25
x = square root 72.25
x = 8.5 inches
Answer:
Thus, volume of pyramid = 
cm³
Step-by-step explanation:
Given: A solid right pyramid has a square base with an edge length of x cm and a height of y cm.
We have to choose from the given options an expression for the volume of the pyramid.
Volume of pyramid = 
Since base is a square with edge length x cm.
Area of square = (side)² = x²
Thus, volume of pyramid = cm³
Answer:
x = 11/36
Explanation:
Step 1 - Write down the equation
x + 4/9 = 3/4
Step 2 - Subtract 4/9 from both sides of the equation
x + 4/9 = 3/4
x + 4/9 - 4/9 = 3/4 - 4/9
x = 11/36
Extra:
If you would like to check and make sure the value of x is correct, simply replace x with its value and solve.
x + 4/9 = 3/4
11/36 + 4/9 = 3/4
27/36 = 3/4
3/4 = 3/4 ✅
So, the value of x is in fact 11/36
Answer:
2x²-8 if it doesnt give you x= if it gives you an x= then comment it and ill work it out.
Step-by-step explanation:
it was pretty simple
Answer:
Step-by-step explanation:
Use similar triangles and proportions to solve:
and cross multiply:
4(6 + x) = 60 and
24 + 4x = 60 and
4x = 36 so
x = 9
