Each piece of board is being cut into 5, so therefore for every one piece of board there will be 5 pieces.
So for pine you would do 100x5 and oak you would do 65x5
That would be your step 1 and 2 which eliminates C and D.
The question asks to find the difference between the two. Which means you need to subtract them to find the difference between the two numbers.
Option A would be correct.
Hope this helps! :)
Answer:
3x
Step-by-step explanation:
What you know
This is an equilateral triangle
the x's are all the same
you could write x + x + x = 3x = 16
Multiplying is just adding repeatedly
The question should say how much water is left in percent or fraction.
Answer:
Step-by-step explanation:
The construction of the figure gives us three right triangles, where we can apply Pythagora's Theorem.
I have added two variables to the image in the picture attached.
On the triangle with sides y,h,16 we have:
On the triangle with sides h,z,25 we have:
Equating :
On the bigger triangle with sides y,z,16+25=41 we have:
Adding this last equation with [1]:
Simplifying:
Operating:
Dividing by 2:
Taking square root:
y=20
To enter the number in the required format:
8² = 64
-1³ = -1
2×2×2×2×2 = 32
64 × -1 = -64
-64 ÷ 32 = -2
