Answer:

Kayden is wrong for multiple reasons: wrong answer and wrong form. The correct answer is 3.6 x 10^7

Step-by-step explanation:

12 x 3 = 36

6 zeros + 1 for moving the decimal on 36 = 7

What is the range of the graph

sladkih [1.3K]

Answer:

Range: [1, 5]

Step-by-step explanation:

The range of a graph is all the y-values that are outputted by x-value inputs.

We see that our range spans from 1 to 5, and since they are closed dots, they are included in our range. Therefore, our range is [1, 5].

A bakery measured the mass of a whole cake as 0.870 kg. A customer bought one slice of the cake and measured the mass of the sli

Shalnov [3]

<h2>The mass of the remaining cake is 0.755 kg.</h2><h3 /><h3>FURTHER EXPLANATION</h3>

The mass of the remaining cake can be obtained straightforwardly by getting the difference of the masses of the whole cake and the cake slice:

$mass \ of \ remaining \ cake \ = mass \ of \ whole \ cake \ - \ mass \ of \ one \ slice$

Sorting the given and plugging them into the equation would give:

$mass \ of \ remaining \ cake \ = 0.870 \ kg - 0.1151 \ kg\\\\\\\boxed {mass \ of \ remaining \ cake = 0.7549 \ kg}$

The problem requires that the answer be expressed with the correct number of significant figures. To do so, recall the rules for determining the number of significant figures needed:

<h3>Significant Figures: Addition and Subtraction </h3>

The final answer must have the same number of decimal places as the given with the least number of decimal places.

<h3>Significant Figures: Multiplication and Division</h3>

The final answer must have the same number of significant figures as the given with the least number of significant figures.

<h3>Significant Figures: Rounding Off Rules</h3>

If the last digit is followed by 1 to 4, it will be unchanged and the other digits dropped. (Example: 1.<u>2</u>34 is rounded to 1.2)
If the last digit is followed by 6 to 9, then it will be increased by one and the other digits dropped. (Example: 1.<u>2</u>64 is rounded to 1.3)
If the last digit is followed by 5:

and 5 is followed by zeros or no digit at all, the last digit will be unchanged if it is even or will increase by one if it is odd. (Example: 1.<u>4</u>50 is rounded to 1.4; 1.<u>5</u>50 is rounded to 1.6)
and 5 is followed by nonzero digits, the last digit is increased by 1. (Example 8.<u>7</u>517 is rounded to 8.8)

Based on the rules above, the final answer to this problem must have 3 decimal places since the given with the least number of decimal places has 3 (0.870 kg). The last digit is 4 (0.75<u>4</u>9 kg) and is followed by the digit 9, hence, it will be increased by one. Based on the rounding rule, the final answer must be:

$\boxed {\boxed {mass \ of \ remaining \ cake \ = 0.755 \ kg}}$
