Richard’s account balance at the end of the week is $ 132.45

<h3>What is Account Balance ?</h3>

The amount of money in a person's bank account is called the account balance of that person

It is given that

Account balance of Richard’s at the beginning of the week = $57.34

Deposits in the week  : $ 163.75

Expenses in the week : Groceries + Credit card bill + Gas

Total Expenses in the week = 25.37 + 50 + 13.27

                                               = $ 88.64

The Richard’s account balance at the end of the week = Account Balance +Total Deposits - Total Withdrawals

= 57.34 + 163.75 - 88.64

Therefore , Richard’s account balance at the end of the week is $ 132.45.

A set of pulleys is used to lift a piano with a mass of 102 kg. The piano is lifted 3 meters in 1 minutes. How much power is use
agasfer [191]

Answer:

50.031 watts

Step-by-step explanation:

Formula

Power = Force * distance / time

The units are critical

distance = meters

time = seconds

force = newtons = kg * m / s^2

Solution

F = m * a

a = 9.81

m = 102 kg

F = 102 * 9.81 = 1000.62 Newtons

T =  minute = 60 sec/min * 1 min

T = 60 seconds

d = 3 meters

Power = 1000.62 * 3 / 60

Power = 50.031

satela [25.4K]

Answer: 15

Step-by-step explanation:

Average is sum of scores/ number of scores, from the question, average is given as 15.

Let the missing score be x

Equation for the questionis represented as: 12 + 18 + x /3 = 15

30 + x /3 = 15

Cross multiply

30 + x = 15×3

30 + x = 45

Subtract 30 from both sides

30 + x -30 = 45 -30

x = 15.

Check:

12 + 18 + 15/3 = 15

45/3 = 15

I hope this is clear, please mark as brainliest answer
