Maria can clean the entire house in two hours. Her sister, Sasha, can clean the house in three hours. How long would it take for

MAXImum [283]

72 minutes

We require their hourly rate of work

Maria cleans $\frac{1}{2}$ the house in 1 hour

Sasha cleans $\frac{1}{3}$ of the house in 1 hour

let x be the time it takes both to clean the house

$\frac{1}{2}$ + $\frac{1}{3}$ = $\frac{1}{x}$

multiply through by 6x

3x + 2x = 6

5x = 6 ⇒ x = $\frac{6}{5}$

Together they can clean the house in 72 minutes

Answer:

(B)1005 feet

Step-by-step explanation:

In the attached diagram

$\angle y =82^\circ\\\angle x =60^\circ$

|AG|=1400 feet

Distance from point C to point G=|CG|

Using Trigonometry in Triangle ACG

$\tan 60^\circ=\dfrac{1400}{CG}\\ CG=\dfrac{1400}{\tan 60^\circ}\\\approx 808$ feet$

Using Trigonometry in Triangle BCG'

$\tan 82^\circ=\dfrac{1400}{CG'}\\ CG'=\dfrac{1400}{\tan 82^\circ}\\\approx 197$ feet$

Therefore, the distance from balloon B from balloon A

=CG+CG'

=808+197

=1005 feet

Choose the composition function that gives the final sale price after a 10% discount is followed by a $150 coupon.

Mice21 [21]

Let's say the function for the discount is f and the function for the coupon is g
f(x)= 0.1x
g(x)= x-150
If you want to the the discount then the coupon, your composition function would look like this:
f(g(x))=0.1(x-150)
Hope this helps!

Answer:

If i did this right the answer would be f(2)=g(2)

both numbers are 2 and the numbers are (x) so x=2
