The area of a triangular block is 64 square inches. If the base of the triangle is twice the height, how long are the base and height of the triangle?
Answers
Answer:
Area of the triangle(A) is given by:
....[1]
where,
b is the base and h is the height of the triangle.
As per the statement:
The area of a triangular block is 64 square inches.
⇒
It is given that: If the base of the triangle is twice the height
⇒ .....[2]
Substitute these in [1] we have;
⇒
or
⇒ inches.
Substitute h =8 in [2] we have;
in.
therefore, the base and height of the triangle are: 16 inches and 8 inches.

Answer:
Step-by-step explanation:
The volume of a sphere is 500 3 πcm3. what is the radius? sphere v = 4 3 πr3 1. substitute value into formula: 500 3 π = 4 3 πr3 2. undo multiplication of 4 3 : 125π = πr3 3. undo multiplication of π: 125 = r3 4. undo cube: 3√125 = r the radius of the sphere is 6 ⇒ 5 cm
Answer:
about 4.9 cm
Step-by-step explanation:
The equation for the volume of a sphere is V= . So, to solve this problem we will plug in 500 for V and solve for the radius,
.
- 500=
- Multiply both sides by 3:
- Divide both sides by 4:
- Divide both sides by
:
- Find the cubed root of both sides:
- The radius is about 4.9 cm

the distance covered by the airplane flying at the of speed in the given period of time is 1610 miles.
Option D) is the correct answer
What is speed?
Speed is simply the time rate at which an object is moving along a given path.
It is expressed mathematically as:
Speed = distance ÷ time
Given data in the question;
- Speed of airplane s = 460 miles per hour
- Time elapsed t = 3.5 hour
- Distance covered d = ?
To determine the distance covered by the airplane, we substitute our given values into the expression above.
Speed = distance ÷ time
460 miles per hour = distance ÷ 3.5 hour
distance = 460 miles per hour × 3.5 hour
distance = 1610 miles
Therefore, the distance covered by the airplane flying at the of speed in the given period of time is 1610 miles.
Option D) is the correct answer

r=12
V=(4/3)pi12^3
V=(4/3)pi1728
V=2304pi in^3
A beach ball has a radius of 12 in.. How much air will the beach ball hold? (leave your answer in terms of π)?
Therefore the answer would be
V = 2304π cubic inches
Another way is?
V = 4/3πr³
r = 12 in.
V = 4/3π(12 in)³
V = 4/3π(1728 in³)
V = 2304π in³
