3b73.03
Bc 730.3/10=73.03
4b 100
Bc 2820/28.2=100

Answer 2

Answer: 2a is 49.73
1b is 30.4
3b is 73.03
4b is 100

for these problems you move the decimal to the right for the end answer depending on how many 0’s are in the number you’re multiplying by. for example, 100•__=3040. you would move the 3040 two decimals to the left since there are two 0s in 100, making the answer 30.4

Therefore, the ratio is 18 : 1

To increase and amount by 17.5 which single multiplier would you use?

Answers

I suppose that the question is 17.5 %.

To increase an amount by a percentage, the multiplier is given by (100 + %)/100

Therefore, to increase an amount by 17.5%,
the single multiplier is given by (100 + 17.5)/100 = 117.5/100 = 1.175

Answer:

B) 12.5%

Step-by-step explanation:

1. Find amount spent on clothes in July

$2800 * 8% = j

j = $224

2. Find amount spent of clothes in August

$224 + $126 = a

a = $350

3. Find the amount's percentage of the total

$350/$2800 = x

x = 0.125 = 12.5%

In which expression should the exponents be multiplied?2 to the power of 9 then 2 to the pwer of 7
(6 to the power of 10)-7
(1/2) to the power of 3*(1/2) to the power of 5
5 to the power of 2 * * 5 to the power of 4

Answers

$\left(a^n\right)^m=a^(n\cdot m)\n\ntherefore,\ your\ answer:\n\n\left(6^(10)\right)^(-7)=6^(10(-7))=6^(-70)$

The answer is (6 to the power of 10)-7

The first has value 2500*(1+.05*9)=3625. The second, similarly, has value 4160, and the third, 3400. Thus, the order, from least to greatest, is third, first, second.
