Answer:
a = (p - b)/2
Step-by-step explanation:
Isolate the variable, a. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
PEMDAS is the order of operation, and =
Parenthesis
Exponents (& roots)

~
First, subtract b from both sides:
p (-b) = 2a + b (-b)
p - b = 2a
2a = p - b
Next, divide 2 from both sides:
(2a)/2 = (p - b)/2
a = (p - b)/2
a = (p - b)/2 is your answer.

Answer:
F
Step-by-step explanation:
A radius of 10 is a diameter of 2*10 or 20
The diameter is a line that goes through the center and touches both sides
Answer:
Therefore Joe is taller than the height of the tepee.
Step-by-step explanation:
Cone:
- Cone is three dimensional shape.
- Slant height of an object is a height that measured along a lateral surface from the vertex to the the base.
- The slant height of a cone is =
- The height of a cone is
- The volume of a cone =
- Lateral surface area is
Given that,
A cone shaped tepee has a radius of 4 feet and slant height of 7 feet.
The height of the cone is
feet
feet
≈5.74 feet
Given that, Joe is 6 feet tall.
Since 6 feet> 5.74 feet
Therefore Joe is taller than the height of the tepee.

4
Step-by-step explanation:
amount = (1/2)/(1/8)
Answer:
84
Step-by-step explanation:
Since we are given line OP perpendicular to line DR, then angles PDR and ODR are right angles.
Angles PDA and ADR are complementary.
Angles ODU and UDR are complementary.
Angles ADR and UDR are given as congruent.
We can conclude that angles PDA and ODU are congruent.
By AA Similarity, triangles APD and UMD are similar.
DP/DM = PA/MU
3.75/10 = 4.5/MU
3.75MU = 10 × 4.5
MU = 12 (altitude of triangle DUO)
OD = OM + MD = 4 + 10 = 14 (base of triangle DUO)
area = base × height / 2
area = 14 × 12 / 2
area = 84
