Debbie estimated that a caterpillar was 4.5 cm long. Later, she found its actual length to be 4.8 cm. Find the percent error.

Answers

Answer:

Step-by-step explanation:

divide 4.5/4.8. you get .9375.

subtract this from 1

1-.9375

and you get 0.0625.

multiply that by 100 to get it into percent form

6.25%

6.25

4.8-4.5
0.3 divide 4.8= 0.062 x 100= 6.25

️What are all the common factors of 15 45 and 90?

Answers

common factors are numbers that all the numbers in question can be divided by and the result will be an integer.

Factors of 15 are 1,3,5 and 15
Factors of 45 are 1,3,5,9,15,45
Factors of 90 are 1,2,3,5,6,9,10,15,18, 30,45,90

So common factors (that they all have) are 1,3,5 and 15

Factors of 15: 1,3,5 and 15. Factors of 45: 1,3,5,9,15,45.
Factors of 90: 1,2,3,5,6,9,10,15,18, 30,45,90.

So common factors for all of them are 1,3,5 and 15

Please Help!Three years ago, Jolene bought $875 worth of stock in a software company. Since then the value of her purchase has been increasing at an average rate of
6 1/2%

per year. How much is the stock worth now? Round the answer to the nearest cent.

The stock is worth $_______now.

Answers

If you would like to know how much is the stock worth now, you can calculate this using the following steps:

1 year: 6 1/2 % of $875 = 6.5% * $875 = 6.5/100 * 875 = $56.875
$875 + $56.875 = $931.875
2 year: 6 1/2 % of $931.875 = 6.5% * $931.875 = 6.5/100 * 931.875 = $60.572
$931.875 + $60.572 = $992.447
3 year: 6 1/2 % of $992.447 = 6.5% * $992.447 = 6.5/100 * 992.447 = $64.509
$992.447 + $64.509 = $1056.956 = $1056.96 = $1057

The correct result would be: The stock is worth $1057 now.

Which equation shows the substitution method being used to solve the system of linear equations?x + y = 6
x = y + 5

A.
x + y = y + 5

B.
x + (y + 5) = 6

C.
x = (x – 6) + 5

D.
(y + 5) + y = 6

Answers

The equation
(y + 5) + y = 6
shows the substitution method being used to solve the system of linear equations. So the correct option among all the options given in the question is option "D".
For a better explanation, let us first write down the two equations given in the question.
x + 5 = 6
and
x = y + 5
Now the thing that has been done is that the value of x in the first equation has been replaced by the value of x that is given in the second equation. this is actually the substitution method of solving equations.

Your answer is D. You're welcome ;-) (Not trying to sound sarcastic, just I wanted to say you're welcome now than never)
