In a fireplace, about 3/4 of an 18 inch log will burn in 1/3 of an hour. How many hours will it take to burn 2 1/2 logs
Karo-lina-s [1.5K]
\bf \begin{array}{ccll}
\stackrel{burned}{log}&\stackrel{time}{hr}\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
\frac{3}{4}&\frac{1}{3}\\\\
2\frac{1}{2}&h
\end{array}\implies \cfrac{\frac{3}{4}}{2\frac{1}{2}}=\cfrac{\frac{1}{3}}{h}\implies \cfrac{\frac{3}{4}}{\frac{2\cdot 2+1}{2}}=\cfrac{\frac{1}{3}}{\frac{h}{1}}

\bf \cfrac{\frac{3}{4}}{\frac{5}{2}}=\cfrac{1}{3}\cdot \cfrac{1}{h}\implies \cfrac{3}{4}\cdot \cfrac{2}{5}=\cfrac{1}{3h}\implies \cfrac{6}{20}=\cfrac{1}{3h}\implies 6\cdot 3h=20\cdot 1
\\\\\\
18h=20\implies h=\cfrac{20}{18}\implies h=\cfrac{10}{9}\implies h=1\frac{1}{9}

about 1 hour and 6 minutes with 36 seconds.

Which linear function represents the line given by the point-slope equation y +7=(x + 6)?
tiny-mole [99]

Answer:

O f(x) = -x-1

Step-by-step explanation:

We want to isolate the 'y' variable, so we will subtract 7 from both sides.

y = x + 6 - 7

y = x -1

if a lady chargers $2.00 for gas and $3.00 per 1/2 hour of work . What is the amount of money she makes in 4 hours ?
anastassius [24]

Answer:

$32

Step-by-step explanation:

The lady charges $2.00 for gas which means over a 4 hour period we would do

4 x 2 = 8

She makes a total of 8 dollars

She also gains $3.00 per half hour of work

This means we would do 3 x 8

24

We add these values to get $32
