A steel ball is dropped from a height and hits the ground 6.7 seconds after its release. From what height (in feet) was the ball released?

Answers

Answer 1

Step-by-step explanation:

Acceleration = g = 32.17ft/s²

Initial velocity = 0ft/s

Time taken = 6.7s

Using Kinematics,

we have s = ut + 0.5at².

=> s = (0)(6.7) + 0.5(32.17)(6.7)²

=> s = 722.06ft.

Micah has 15 games. Micah has three more games than kelly. Kelly has K number of games. Move values into the boxes to create an equation to represent this senerio

Answers

Answer:

Equation = K + 3 = 15

K = 12 games

Step-by-step explanation:

According to the scenario, calculation of the given data are as follows,

Micah games = 15

Let, Kelly games = K

As Micah has three more games than Kelly, then

K + 3 = 15

K+3 = 15

K = 15 - 3

K = 12

Hence, Kelly has 12 games.

Step-by-step explanation:

You could multiply .25 times 24 to get the answer because changing 25% to a number you can use in an equation means adding a decimal place and moving two places to the left.

Write an expression for the age of:
Her mum
Her brother

Answers

Answer:

Ebony's brother is x + 4 years old.

Ebony's mum is 3x years old.

Explanation:

Since Ebony is x years old, and her brother is 4 years older than her, the expression is x + 4, as her brother is +4 years older.

Ebony's mum is 3 times Ebony's age, which is x. 3 times x is shortened into 3x.
