a. Shaunnie's mistake was that she multiplied 10 times 5. When you multiply 10x5, it is the same as 10+10+10+10+10. However, the question asked about 10⁵. 10⁵ means 10 to the fifth power which is the same as 10x10x10x10x10. She needs to multiply 10 to itself, ten times. This equals 1,000,000.
b. Marlon made the mistake of not moving the decimal point. Marlon added the two zeros to the end when he multiplied 2.5 to 10² because 10² is the same as 100. However, when multiplying with a decimal, the decimal needs to move as well. He needs to move the decimal place to the right two places. His answer should be 250. The last zero is dropped because it is to the right of the decimal and not followed by another number.
<h3>Further Explanation</h3>
Numbers to the nth power.
When a number has a power as in 10², this means that you multiply that number by itself however many times the power indicates. A number to the 29th power would be multiplied by itself 29 times.
Multiplying Decimals
When multiplying decimals, it is important to remember to shift the decimal to the correct place. A number multiplied by ten moves the decimal one place to the right. A number multiplied by 100 moves the decimal two places to the right. A number multiplied by 1000 moves the decimal three places to the right. A trick for remembering is the number of zeros in 10, 100, or 1000. For each zero, move the decimal

Answer:
∠ 1 = 20 x + 5
∠ 2 = 24 x - 1
If lines l and m are parallel:
∠ 1 + ∠ 2 = 180°
20 x + 5 + 24 x - 1 = 180
44 x + 4 = 180
44 x = 180 - 4
44 x = 176
x = 176 : 44
x = 4°

Step-by-step explanation:
A Canadian postal code looks like this:
K1A 3B1 .
So you have: letter - digit - letter - digit - letter - digit .
The question doesn't say anything about restrictions on
which letters can be used, or restrictions on repeating letters
or digits within one postal code. So as far as we know, each
letter can be any one of 26, and each digit can be any one of 10.
The total number of possibilities would be
(26·10·26) · (10·26·10) = 17,576,000 .
In the real world, though, (or at least in Canada), Postal codes
don't include the letters D, F, I, O, Q or U, and the
first letter
does not use W or Z. When you work it out with these restrictions,
it means there's a theoretical limit of 7.2 million postal codes.
The practical limit is a bit lower, as Canada Post reserves some
codes for special functions, such as for test or promotional purposes.
One example is the code H0H 0H0 for Santa Claus ! Other special
codes are for sorting mail
bound for destinations outside Canada.
At the present time, there are a little over 830,000 active postal codes.
That's about 12% of the total possibilities, so there are still plenty of codes
left for expansion.
<span>10 mg = 1 cg
100 cg = 1 g
1000 g = 1 kg.
Thus, 0.953 kg = 1000 x 0.953 = 953g
0.953 kg = 0.953 x 1000 x 100 = 95,300cg
0.953 kg = 0.953 x 1000 x 100 x 10 = 953,000 mg
Therefore, from the give options, 9,530cg is not the same as 0.953 kilograms.
Therefore, the correct answer to the question "Which of the following is not the same as 0.953 kilograms?"is 9,530cg</span>
