The height of a square pyramid-shaped gift box is one half the length of

Mathematics
1 answer:
Irina-Kira [14]3 years ago
3 0

Answer:

15 inches

Step-by-step explanation:

Volume of a pyramid = 1/3 x ( length² x height)

4500 = 1/3 x ( length² x height)

height = 1/2 x length

4500 = 1/3 x ( length² x 1/2length)

multiply both sides of the equation by 6

27000 =  ( length² x length)

find the cube root of 27300

length = 30

height = 1/2 x 30 = 15in

For a moving object the force acting on the object varies directly from the objects acceleration when a force of 25 N acts on a
77julia77 [94]

Answer:

2m/s²

Step-by-step explanation:

If for a moving object the force acting on the object varies directly from the objects acceleration, then it can be expressed as:

F∝a

F = ka.

F is the force

a is the object's acceleration

From the expression;

k is the constant of proportionality

When an initial force of 25 N acts on the object and the acceleration of the object is 5 m/s², then

k = 25/5

k = 5Ns²/m

If the force exchange to 10 N, the acceleration of the object will be gotten using the relationship above

F = ka

Given F = 10N and k = 5Ns²/m

a = F/k = 10/5

a = 2m/s²

The acceleration of the object will be 2m/s²

What is the volume of a right circular cylinder with a base diameter of 6 m and a height of 5 m? express you answer using pi
OlgaM077 [116]
Well the formula to solve for the volume of a right circular cylinder would be, V=πr2h. For the radius, the number inserted into the formula would be half of the diameter measurement. Therefore, the radius would be 3 m. As for the height measurement, the number would remain the same of 5m. Once all figures are applied to the formula: V=π(3^2)(5), the answer could then be rounded either to the tenths or hundredths depending on what your teacher asks for. The answer in the end would come down to approximately 141.37 meters cubed.

How can I solve this equation 5x^2-2x-6=-2x^2+9x
wel
Add 2x^2 to both sides
7x^2-2x-6=9x

Subtract 9x from both sides
7x^2-11x-6=0

Factor by using slip and slide
x^2-11x-42
(x-14)(x+3)
(x-14/7)(x+3/7)
(x-2)(7x+3)

Then use the Zero Product Property to find roots
x-2=0
x=2

7x+3=0
7x=-3
x=-3/7

Final answer: x=-3/7, x=2
