I put in a wrong denominator...try 4/3 in fraction form, or 1 and 1/3 as a mixed numeral.

$\bf \cfrac{6}{7}\div \cfrac{9}{14}\implies \cfrac{6}{7}\cdot \cfrac{14}{9}\implies \cfrac{\underline{3}\cdot 2}{\underline{7}}\cdot \cfrac{2\cdot \underline{7}}{3\cdot \underline{3}}\implies \cfrac{2\cdot 2}{3}\implies \cfrac{4}{3}\implies 1\frac{1}{3}$

Suppose f varies directly as g, and f varies inversely as h. Find g when f = 10 and h = –12, if g = 56 when h = –2 and f = –7. R

kow [346]

Answer:

-480

Step-by-step explanation:

If f varies directly as g, and inversely as h, then we can write the variation equation:

$f=\frac{kg}{h}$ , where k is the constant of variation.

If g=56 when h=-2 and f=-7, then we substitute these values into the formula to find the value of k.

$-7=\frac{k(56)}{-2}$

$-7\times -2=56k$

$k=\frac{14}{56}=\frac{1}{4}$

The equation now becomes:

$f=\frac{g}{4h}$

if f=10 and h=-12, then;

$10=\frac{g}{-48}$

$g=-48\times 10=-480$

The correct answer is B.

The Brown Office Rental Company has purchased a new computer for the secretary to use for customer requests. She can type 70 wor

Vladimir [108]

First you want to find how many words she types per hour.
There are 60 minutes in 1 hour.
So multiply 70 words/min times 60 min/ 1 hr to cancel out the minutes.
You will get 4200 words / hr
Then multiply 4200 by 4 and 5
use * as multiplication symbol
4200 words/hr * 4 = 16,800 words/hr
4200 words/hr * 5 = 21,000 words/hr
She will type 16,800 - 21,000 words/hr

So Your answer is going to be letter G
