10^-2 + 8 round the coefficient to two decimal places​

Answers

Answer 1

Answer:

I believe it is .0801

Step-by-step explanation:

- A negative exponent will always turn into a fraction

- First change it to a fraction

1/10^2

- Simplify the exponent

10 times 10 = 100

- Change the fraction

1/100 or in decimal form which is 0.01

- Now the addition

8 + 0.01 = 8.01

- Move decimal to two decimal places

.0801

Answer 2

Answer:    .0801 is what I got because the way I understand it 10^(-2) + 8 =8.01 and you said round it to the coefficient to 2 decimal places. so I moves the 8 over 2 times because 8 is the coefficient and I got .0801

Hope it helped and I got it right

Students in the science lab are measuring the mass of an object on a triple beam balance. The object has a mass of 38 grams. Complete the table below with the absolute and percent error for each students’ measurement. Round your answer to the nearest tenths place.

Answers

Answer:

The answer is 40

Step-by-step explanation:

have a nice day!

The absolute error of Danielle, Iris, and HB is 2,6 and 1 gram respectively. The percentage error of Danielle, Iris, and HB  are 5%,15%, and 2.5%  respectively.

What is the percentage?

The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.

The percentage is also called the indicating hundredths. Thus, 2% is two-hundredth, which means 2%=2/100=0.02.

As per the given,

Actual mass = 38

Danielle error = 40 - 38 = 2 grams

% error = 2/40 x 100 = 5%

Iris error = 4 - 34 = 6 grams

% error = 6/40 x 100 = 15%

HB error = 41 - 40 = 1 grams

% error = 1/40 x 100 = 2.5%

Hence "The absolute error of Danielle, Iris, and HB is 2,6 and 1 gram respectively. The percentage error of Danielle, Iris, and HB  are 5%,15%, and 2.5%  respectively".

1.) Last week Joy ran 20 miles more than Olivia. Joy ran 43 miles. How many miles did
Olivia run?
x = the number of miles Olivia ran
Write the equation to represent this situation. (Do not use any spaces in your equation)
2.) Kim rented a bounce house for a party. There was a one-time charge of $100, plus an hourly rate of $35. Her total cost for the night was $327.50. For how many hours did Kim rent the bounce house?
h = the # of hours Kim rented the bounce house
Write the equation to represent this situation. (Do not use any spaces in your equation)

Answers

Answer:

1. x=43miles-20miles

2.h=($327.50-$100)/35

Step-by-step explanation:

1. The answer is x=43miles-20miles. This is because Joy ran more miles than Olivia. So to find the time olivia ran you say 43 minus 20.

2. The answer is h=($327.50-$100)/35. This is because you remove ( subtract ) the one time charge in order to get the hour charges. Then to find the number of hours Kim rented the bounce house you divide by 35 because this is the price for an hour.
