37. Two years ago, Bob flew 6 x 105 miles in an airplane. This was 15 times as many

gogolik [260]

Answer:

A. 4·10⁴

Step-by-step explanation:

The problem statement tells you ...

6×10⁵ miles = 15 × (last year's mileage)

Dividing by 15 gives ...

(60×10⁴ miles)/15 = (last year's mileage) = 4×10⁴ miles

_____

<em>Further explanation</em>

An exponent is an indication of repeated multiplication.

10⁵ = 10·10·10·10·10 = 100,000

We can use the associative property of multiplication to rewrite the number of miles:

6×10⁵ = 6·(10·10·10·10·10) = 600,000 = (6·10)·(10·10·10·10) = 60×10⁴

On Saturday Stella worked for two hours helping her mother in the house. she spent 1/3 of her time doing laundry, 1/4 of a time

raketka [301]

$\bf \stackrel{\textit{total hours time}}{2}-\cfrac{1}{3}-\cfrac{1}{4}\impliedby \textit{we'll use an LCD of \underline{12}}
\\\\\\
2-\cfrac{1}{3}-\cfrac{1}{4}\implies \cfrac{(12\cdot 2)~-~(4\cdot 1)~-~(3\cdot 1)}{12}\implies \cfrac{24-4-3}{12}\implies \cfrac{17}{12}
\\\\\\
\textit{12 goes into 17 \underline{1 time} and it has a \underline{remainder} of 5 }\implies 1\frac{5}{12}$

which is one hour and 25 minutes.
