Step-by-step explanation:
surface area if pyramid=area of base+combined area of lateral faces.
area of base=8×8=64
combined area if lateral faces=area of one triangle:area=base×height
=8×12=96
Total surface area=64+96
=160m square
Answer:
B
Step-by-step explanation:
Since LMNO is a parallelogram then MN and LO are parallel, thus
∠OLN = ∠MNL = 20° ( corresponding angles )
Answer:
I believe what you would have to do is add each number so the top left box would be two and the bottom right would be 11
Step-by-step explanation:
Answer: 250 hamburgers
Step-by-step explanation: x= hamburgers
If there are 72 more cheeseburgers than hamburgers there are:
x+72
The number of cheeseburgers and hamburgers=572 so:
572= x+72+x
Then solve
572=x+72+x
572=2x+72
-72 -72

500=2x
500/2=2x/2
250=x
Answer:
x=1 meter
Step-by-step explanation:
step 1
Find the area of the rectangular pool
we have
substitute
step 2
Find the area of rectangular pool including the area of the walkway
Let
x ----> the width of the walkway
we have
substitute
step 3
Find the area of the walkway
To find out the area of the walkway subtract the area of the pool from the area of rectangular pool including the area of the walkway
so
step 4
Find the value of x if the area of the walkway equal the area of the pool
so
Solve the quadratic equation by graphing
The solution is x=1 meter
see the attached figure
