Nonamiya [84]

Answer: 2.72 hours

Step-by-step explanation:

Let's call $t_1$ while it takes Wade to paint the room

Let's call $t_2$ while it takes Rhonda to paint the same room.

Then we know that:

$t_1 = 5\ hours\\t_2 = 6\ hours$ .

Let's call it t as it takes Rhonda and Wade to paint the same room working together.

Now we use the following formula to calculate t.

$\frac{1}{t}=\frac{1}{t_1}+\frac{1}{t_2}$

$\frac{1}{t}=\frac{1}{5}+\frac{1}{6}$

$\frac{1}{t}=\frac{11}{30}$

$t=\frac{30}{11}$

$t=2.72\ hours$

If they work together they will be able to paint the room in 2.72 hours

The polygons are similar. Find x and y. The images are not drawn to scale.

Alja [10]

The correct answer to this question is letter "D. x = 21, y = 14."
18 : 12
27 : x - 3
24 : y + 2

18 / 12 = 27 / x - 3
3 / 2 = 27 / x - 3
54 = 3x - 9
3x = 54 + 9
3x = 63
x = 21

18 / 12 = 24 / y + 2
3 / 2 = 24 / y + 2
48 = 3y + 6
3y = 48 - 6
3y = 42
y = 14
