Suppose you want 50% of x amount. You'd divide the x by .5. Or if you wanted 30%, divide by .3

A company needs 713 slices of pizza for a company party. If each pizza is cut into 8 slices, about how many whole pizzas should

alukav5142 [94]

Answer:

Step-by-step explanation:

To find the number of WHOLE pizzas needed, we need to divide the total number of slices needed (713) by 8 slices. Thus

$\frac{713}{8}=89.125$

<em>because we can't order fractional pizza, we need to round up. So we will need 90 pizzas.</em>

<em>Correct answer is D.</em>

Two cars traveled equal distances in different amounts of time. Car A traveled the distance in 2 h, and Car B traveled the dista

lidiya [134]

Recall your d = rt, distance = rate * time.

notice, the distance are the same, say it was "d" miles.

and if car A is travelling at a speed of say "r" mph, then B is going at "r+15" mph.

$\bf \begin{array}{lccclll}
&\stackrel{miles}{distance}&\stackrel{mph}{rate}&\stackrel{hours}{time}\\
&------&------&------\\
\textit{Car A}&d&r&2\\
\textit{Car B}&d&r+15&1.5
\end{array}
\\\\\\
\begin{cases}
\boxed{d}=2r\\
d=1.5(r+15)\\
----------\\
\boxed{2r}=1.5(r+15)
\end{cases}
\\\\\\
2r=1.5r+22.5\implies 0.5r=22.5\implies r=\cfrac{22.5}{0.5}\implies \boxed{r=\stackrel{mph}{45}}$

how far is B going? well, r + 15.

Write an equation in point slope form for the line through the given point with the given slope (-10,-1) m=-1

notsponge [240]

Answer:

y + 1 = -(x + 10)

Step-by-step explanation:

Point-Slope Form: y - y1 = m(x - x1)

The given coordinate (-10, -1) are your (x1, y1), so:

x1 = -10
y1 = -1
m = -1

All you have to do is substitute the given information into the formula:

y -(-1) = -1(x -(-10)), which will simplify to y + 1 = -(x + 10)

Remember: Double negatives make a positive so if the given coordinates for (x1, y1) are negatives, they will be added to y or x in point-slope form, not subtracted.
