Interest earned: $84
Principal: $600
Interest rate: 7%
Time: ?

Answers

84(600 x 0.07)
= 2yrs
Rate: 7/100 = 0.07

Answer:

2 years

Step-by-step explanation:

The simple interest formula is equal to -  A = P (1  + rt)  Where:

A is the Final Investment Value

P is the Principal amount of money to be invested

r is the rate of interest  

t is Number of Time Periods

In this problem we have:

t = ? years

P = $600

A + $600 + $84 = $684

r = 0.07

A substitute in the formula above would be:

$684 = $600(1 + (0.07)t)

solve for t :

t = [(684/600) - 1]/0.07 = 2 years

Sara’s boss informed her she is getting a 5% raise. She currently makes $22 per hour. What is her new hourly wage?

Answers

22(0.05) = 1.1
You have to add this new amount of money to the old so 22+1.1

Answer:

Her new hourly wage would be $23.10

Step-by-step explanation:

First you want to find out how much her raise now is in dollars:

0.05 x 22 = 1.10   (Turn the 5% into a decimal by moving the dot two places to the left)

Now add that to what she makes per hour:

1.10 + 22.00 = $23. 10

Explain why the value of 0.6 is greater than the value of 0.39.
---
i know why... i just need help explaining plz! i will give brainliest

Answers

Answer:

the value 0.6 is greater than 0.39 bc 0.6 is a bigger value than 0.39 as u go down the values get more bigger and as u go up the values get more smaller. try this if not then I will tell u another thing.

Answer is 0.60 > 0.39

Decimal place value:

The decimal place value is the place value of the digits in a decimal number. We know that place value is the numerical value represented by a digit in a number.

Ex: 0.50 > 0.49 as the tenth place of 0.50 is more than 0.49.

Here,

0.6 = 0.60

0.60 > 0.39 as the tenth place of 0.6 i.e., 6 is greater than 0.39 i.e., 3.

Answer:

c) x=13

Step-by-step explanation:

4x + 2 = 90 − 36

Step 1: Simplify both sides of the equation.

4x + 2 = 90 − 36

4x + 2 = 90 + −36

4x + 2 = (90 + −36) (Combine Like Terms)

4x + 2 = 54

4x + 2 = 54

Step 2: Subtract 2 from both sides.

4x + 2 − 2 = 54 − 2

4x = 52

Step 3: Divide both sides by 4.

4x/ 4  =  52/ 4

x=13

if you need a shorter way to get this... is to do what i did and just used MathPapa's algebra calculator and put in "4x + 2 = 90 - 36" cause that's basically what the question is asking you to use... im not saying to do my method... im just saying that's how i got it
