Answer:

see below

Step-by-step explanation:

Let y = the total cleaning cost

Let x = the number of roots cleaned.

Therefore, if the cost is $22 per room, y = 22x

200 = 22x

Divide both sides by 22: 9 $\frac{2}{22}$ = x

Therefore, 9 rooms can be cleaned for $200

New equation: y = 22x + 40

200 = 22x + 40

Subtract 40 from each side: 160 = 22x

Divide both sides by 22: 7 $\frac{6}{22}$ = x

Therefore, 7 rooms can be cleaned for $200 if the carpet cleaners receive a $40 tip

When two six-sided dice are rolled what is the probability that the product of their scores will be greater than six?

Pachacha [2.7K]

Answer: $\bold{\dfrac{11}{18}}$

<u>Step-by-step explanation:</u>

Think of the products row by row:

11 12 13 14 15 16 - 0 products greater than 6

21 22 23 24 25 26 - 3 products greater than 6

31 32 33 34 35 36 - 4 products greater than 6

41 42 43 44 45 46 - 5 products greater than 6

51 52 53 54 55 56 - 5 products greater than 6

61 62 63 64 65 66 - 5 products greater than 6

$\dfrac{\text{number greater than 6}}{\text{total possible outcomes}}=\dfrac{22}{36}=\dfrac{11}{18}\ when\ reduced$

If both cars in Exercise 62 are on one side of the plane and if the angle of depression to one car is 38∘ and that to the other

Sati [7]

The two cars lying on one side of the plane are 50 meters apart.

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more numbers and variables.

let us assume that the height is 100 m. Let d represent the horizontal distance. For depression of 38°, Ф = 90 - 38 = 52°, hence:

tan(52°) = d / 100

d = 128 m

For depression of 52°, Ф = 90 - 52 = 38°, hence:

tan(38°) = d / 100

d = 78 m

Distance apart = 128 - 78 = 50 m.

The two cars lying on one side of the plane are 50 meters apart.
