What is Depreciation?

Depreciation refers to when the value of something goes down over time. The value of a car usually decreases in value with time. Therefore, its value is said to depreciate.

Given that, it is estimated that an iceberg weighs 84000 tonnes. As the iceberg moves into the warmer water, its weight decreased by 25% each day.

Depreciates by 25%, so 100% - 25% = 75%

75% of, 84000 for 3 days:

= (75 / 100)³ × 84000

= (0.75)³ × 84000

= 35437.5

Therefore, the iceberg will weigh 35000 tonnes correct to 2 significant figures.

Tina solved an equation incorrectly, as shown below:Step 1: 8x = 24
Step 2: x = 24 − 8
Step 3: x = 16

Which statement best explains why Step 2 is incorrect in Tina's solution?

She did not divide 24 by 8.
She did not add 8 to 24.
She did not multiply 24 by 8.
She did not multiply 24 eight times.

Answers

Answer: The correct statement is (A) She did not divide 24 by 8.

Step-by-step explanation: Given that Tina solved an equation incorrectly, as shown below:

Step 1: 8x = 24

Step 2: x = 24 − 8

Step 3: x = 16.

We are to select the correct statement that best explains the reason behind Step 2 incorrect.

The correct steps of the solution are

$\textup{Step 1: }8x=24\n\n\textup{Step 2: }x=(24)/(8)\n\n\textup{Step 1: }x=3.$

Therefore, we see that in step 2, Tina should divide 24 by 8, which she did not do and got the incorrect answer.

Thus, the correct statement is (A). She did not divide 24 by 8.

$8x = 24 \n \n x = (24)/(8) \ / \ divide \ by \ 8 \n \n x = 3 \ / \ simplify \n \n$

Seeing the correct steps above, the mistake that Tina made was that she did not divide 24 by 8.

First, you'd have to turn the fraction into a decimal.You would divide the numerator by the denominator. 7/8=0.875
Now, you turn the decimal to a percent.
You move the decimal point two places to the right.
087.5
87.5% would be your answer.

$(7)/(8)\cdot100\%=(7)/(2)\cdot25\%=(175)/(2)\%=87.5\%$

Which fraction is equal to 0.8? A. 1/8 B. 8/10 C. 1/80 D. 8/100

Answers

Answer: 8/10

Step-by-step explanation: Using the place value chart, we can see that 0.8 means eight-tenths which can be written as the fraction 8/10. Since 8/10 is not in lowest terms, we need to divide both the numerator and denominator by the greatest common factor of 8 and 10 which is 2 to get 4/5.

Therefore, 0.8 can be written as the fraction 8/10.

b is the answer but if you reduce it , it will be 4/5
