Answer:
O 40
Step-by-step explanation:
because if you are doing algebra the term for a number is a letter and instead of doing 4xO you substituted to 4O
A= 20x25 so the area is 500
To find the perimeter you have to add both the width and length x2 so it’s 20+25 =45
45x2=90
Answer:
2x³- 2px² + p + 2
First plug in x = -3
2(-3)³- 2p(-3)² + p + 2
According to PEMDAS, we should solve the exponents first.
(-3)³ = -27
(-3)² = 9
2(-27) - 2(9)p + p + 2
Now multiply.
-54 - 18p + p + 2
Now combine the variables and constants.
-17p - 52
This is the simplified expression.
If it is an equation, then it would equal 0.
-17p - 52 = 0
To solve for p, add 52 to both sides.
-17p = 52
Now isolate the p by dividing by -17.
p = -52/17 or -3.0589
The second ball would most likely be red and there are 5 red balls in the bag. And if you replaced the ball it would most likely be the same ball.
Answer:
Option B. 93.46 ft³
Step-by-step explanation:
In the given question tow solids are given.
Their heights are same and the cross sectional areas at every level parallel to the respective bases are same which means total volume of solids are also same.
We have to find the volume of the cone.
We know the formula of volume of a pyramid 
Now area of the base = area of a right angle triangle = 
Here height of the right angle triangle = 8 ft
and base of the triangle = 
Now area of base = 
Now volume of cone = volume of pyramid = 
Therefore Option B. is the answer.
