You should start with an equation.
245 = 125 + 15x
The 'x' represents the week.

so now, we have to subtract 125 from the total amount which is 245.
245 - 125 = 120
now we have
120 = 15x
to find 'x', we must divide 15 on each side
\frac{120}{15}  =  \frac{15x}{15}
we are now left with
8 = x
that means Sierra will have 8 weeks until she has enough money to buy the bike

Klio2033 [76]
She worked 2 and 1/2 hours yesterday, and today she did 4 and 1/4 hours.

first off, let's check how many hours she worked total, and divide 54 by it.

so, first off, let's convert the mixed fractions to "improper" and add them up.

\bf \stackrel{mixed}{2\frac{1}{2}}\implies \cfrac{2\cdot 2+1}{2}\implies \stackrel{improper}{\cfrac{5}{2}}
\\\\\\
\stackrel{mixed}{4\frac{1}{4}}\implies \cfrac{4\cdot 4+1}{4}\implies \stackrel{improper}{\cfrac{17}{4}}\\\\
-------------------------------

\bf \cfrac{5}{2}+\cfrac{17}{4}\impliedby \textit{our LCD will be 4}\implies \cfrac{(2\cdot 5)+(1\cdot 17)}{4}
\\\\\\
\cfrac{10+17}{4}\implies \cfrac{27}{4}\implies \stackrel{total~hours}{6\frac{3}{4}}
\\\\\\
\cfrac{\stackrel{wages}{54}}{\stackrel{hours}{6\frac{3}{4}}}\implies \cfrac{54}{\frac{27}{4}}\implies \cfrac{\frac{54}{1}}{\frac{27}{4}}\implies \cfrac{54}{1}\cdot \cfrac{4}{27}\implies \cfrac{216}{27}\implies 8~\frac{\$}{hr}

The density of lead is 11.4g/cm^3 at 25 degrees C. Calculate the volume occupied by 25.0g of lead
ElenaW [278]

Answer:

2.193 cm³

Step-by-step explanation:

density is mass divided by volume:

density =  \frac{mass}{volume}

you can manipulate the formula by multiplying with volume:

density \times volume = mass

then dividing by density:

volume =  \frac{mass}{density}

in this case:

volume =  \frac{25g}{11.4 \frac{g}{cm}  }  = 2.193 { \: cm}^{3}
