What is the exponential notation for 262,144

7nadin3 [17]

since there is always a decimal at the end of every value so :

= 262144.0

you move the decimal backwards if there is no decimal between the value. you place the decimal after the 1st digit, you will also count the digits you have passed :

= 2.62144 X 10^5

you passed 5 values so you put 5 in exponent form.

Leticia charges $8 per hour to babysit. She babysat Friday night for 4 hours,

Dmitriy789 [7]

For this case we have that the variable "x" represents the number of hours that Leticia uses to take care of children on Saturday.

IF on Friday I use 4 hours ($ 8 each) and on Saturday "x" hours ($ 8 each) obtaining a profit of $ 72, we have the following equation:

$8 (4 + x) = 72$

We apply distributive property:

$32 + 8x = 72\\8x = 72-32\\8x = 40\\x = \frac {40} {8}\\x = 5$

So, on Saturday she spent 5 hours.

Answer:

$8 (4 + x) = 72\\x = 5$

Fraction multiplying by fractions

Amanda [17]

$\bf \cfrac{2}{9}\times a=\cfrac{3}{15}\implies \cfrac{2a}{9}=\cfrac{1}{5}\implies 2a=\cfrac{9\cdot 1}{15}\implies 2a=\cfrac{3}{5}
\\\\\\
a=\cfrac{3}{2\cdot 5}
\implies 
a=\cfrac{3}{10}\\\\
-------------------------------\\\\
\cfrac{2}{5}\times b=\cfrac{7}{12}\implies \cfrac{2b}{5}=\cfrac{7}{12}\implies 2b=\cfrac{5\cdot 7}{12}\implies 2b=\cfrac{35}{12}
\\\\\\
b=\cfrac{35}{2\cdot 12}\implies b=\cfrac{35}{24}$
