Answers

Answer:

7.4 % is percent error

Step-by-step explanation:

https://brainly.com/question/21689164

The percent of error is 7.4%. The correct option is B.

What is a percentage?

A ratio or value that may be stated as a fraction of 100 is called a percentage. And it is represented by the symbol '%'.

Given:

Estimated value: 231

Actual value: 215

To find the percentage:

First, the value,

= 231 - 215

= 16

Now,

let n be the percentage.

So,

16 = n x 215/100

n = 1600/215

n = 7.4%

Therefore, 7.4% is the error.

2/3•x-9=12 solve for x?

Answers

Answer:

31.5

Step-by-step explanation:

Ok.

2/3x - 9 = 12

2/3x = 21

x = 21*(3/2)

x = 63/2 = 31.5

Answer:

[tex]x=\frac{63}{2}[/tex]

Step-by-step explanation:

[tex]\frac{2}{3} \times x-9=12[/tex]

Add 9 to both sides:

[tex]\frac{2}{3}x-9+9=12+9\\\frac{2}{3}x=21[/tex]

Multiply both sides by 3/2:

[tex](\frac{3}{2} )\times(\frac{2}{3}x)=(\frac{3}{2} )*(21)\\x=\frac{63}{2}[/tex]

x = 63/2 is your answer.

When Martin graduates college, he is gifted $1,200 and puts the money into a savings account that earns 2.2% annual interest. How much money will Martin have in 2 years? How much money will Martin have in 5 years?

Answers

Answer:

2 years = 1252.80 5 years =1332

Step-by-step explanation:

1,200 x 2.2% = 26.4

1200 + 52.80 = 1252.80

26.40 x 5 =132

1200 + 132 =1332

Exponential Function
Solve

Answers

The answer would be ≈$20,440

If it depreciates at a rate of 5.2% each year, for 8 years
5.2•8=41.6
Divide 35,000 by 100 to get how much each percent would be worth
35,000/100=350
Multiply 350 by 41.6 to get the amount of money depreciated out the total price
350 • 41.6 = 14,560
Than subtract 14,560 out of 35000 to see the current price of the printer
35,000 - 14,560 = 20,440
