Answer:
368 sq. units.
Step-by-step explanation:
We have a square of side lengths 20 units and we cut four congruent isosceles right triangles from the corners of the square.
Now, the four isosceles right triangles have one leg equal to 4 units.
Therefore, the area of four triangles = 
sq. units.
Now, we have the area of the given square is (20 × 20) = 400 sq. units.
Therefore, the area of the remaining octagon will be (400 - 32) = 368 sq. units. (Answer)
Step-by-step explanation:
solve for surface area
A=6a^2
a=edge
4/20 is 0.20, which is equivalent to 20%.
Remember that 1.0=100%, 0.5=50%, 0.2=20%, 0.05=5%, and so on.
Answer:
37.7
Step-by-step explanation:
The orginal answer is 37.699
But you want to round the tenth
So 9 to the 6 you want to rasie the score
6 turns into a 7 and the numbers behind it (9 and the other 9) turn into a zero
37.7 or 37.700
Answer:
To get answer A, Dave took 47*5 = 235
Step-by-step explanation:
There are 147 containers that contain 5 gallons each. We need to multiply to find the total number of gallons.
total number of gallons = containers * number of gallons per container
= 147* 5 gallons per container
=735 gallons
To get answer A, Dave took 47*5 = 235
