<h3>What are Arithmetic operations?</h3>

Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions. The operator that performs the arithmetic operation is called the arithmetic operator.

- Subtraction operation: Subtracts the right-hand operand from the left-hand operand.

for example 12 -2 = 10

* Multiplication operation: Multiplies values on either side of the operator

For example 12*2 = 24

You have accepted a job offer at an annual salary of $36,980.

This salary includes a year-end bonus of $2900

So your gross pay = 36980 + 2900 = 15952

You are paid twice per month

12 months × 2 checks = 24 paychecks

15952/ 25= 1595.2

Hence, your gross pay will be $1595.2 for each paycheck

Answer:

7.1

Step-by-step explanation:

- Find mean

- For each number you subtract the mean and square the result.

- Work out the mean of those squared differences and find square root of that.

- Hope that helped! Let me know if you need further explanation.

Rain fell on four days in June. These amounts were recorded: 5 mm, 9 mm, 2 cm, and 2.6 cm. What was the total rainfall for June?

ivolga24 [154]

Hello there

The correct answer in mm would be 60 mm

1 cm = 10 mm

So it would 5+9+20+26 = 60

In cm it would be 6 cm

10 mm = 1 cm

.5+.9+2+2.6 = 6

I hope this helped ^^

Answer:

Step 4

Step-by-step explanation:

Given: Steps used by Shelly to evaluate the expression

To find: step that includes Shelly's mistake

Solution:

According to PEMDAS,

P denotes Parentheses

E denotes Exponents

M denotes Multiplication

D denotes Division

A denotes Addition

S denotes subtraction

Step 3 is $-20\div 5-1$ and step 4 is $-20\div 4$

In step 4, first subtraction operation has been applied before the division operation.

There is a mistake in step 4 as according to PEMDAS, first -20 should be divided by 5 then 1 should be subtracted from the resultant number.

LekaFEV [45]

I think I know how to do it

Your equation is:

P₁V₁ = P₂V₂

You Know:

Initial:

P₁ = 84 Pa

V₁ = 336 L

New:

P₂ = ?

V₂ = 216L

Plug this into the equation:

P₁V₁ = P₂V₂

(84 Pa)(336 L) = P₂(216 L) Divide 216 on both sides

$\frac{(84Pa)(336L)}{216L}=\frac{(P_{2})(216L)}{216L}$

130.6666666 = P₂

(if your doing significant figures, you have 2 sig figs)

130 Pa = P₂
