Answer:

40 and 202.5 m³

Step-by-step explanation:

(7)

Since the figures are similar then the ratios of corresponding sides are equal, that is

\frac{PQ}{16} = \frac{30}{12} ( cross- multiply )

12 PQ = 480 ( divide both sides by 12 )

PQ = 40 in

The volume (V) of a pyramid is calculated as

V = \frac{1}{3} Ah ( A is the area of the base and h the height ) , then

V = \frac{1}{3} × 9² × 7.5

   = \frac{1}{3} × 81 × 7.5

   = 27 × 7.5

   = 202.5 m³

The taxi costs $2.25 for the first mile plus 15cents for each additional tenth of a mile. For a 5.2 mile trip, Eric payed $10 an
Verizon [17]
2.25 for the first mile. That leaves 4.2 miles.

4 * 0.1 = 0.4

0.15 * 4 = $6.00

0.15 * 2 = 0.3

$6.30 + $2.25 = $8.55

$10.00 - $8.55 = $1.45

The driver's tip was $1.45.

A family swimming pool holds 61 m3 of water. It loses 0.27m3 of water to evaporation each day. This situation can be represented
Bezzdna [24]

Answer:

The answer to your question is: when x = 100 days, y = 34 m³

Step-by-step explanation:

Data

Volumen = 61 m³

Loses 0.27 m³ each day

Equation    y + 0.27x = 61

when x = 100, y = ?

Process, just substitute x in the equation and solve it for y

                  y + 0.27(100) = 61

                  y + 27 = 61

                  y = 61 - 27

                  y = 34 m³

It means that after ten days, the swimming pool will only have 34 m³, because 27 m³ will have evaporated.

Find the measure of angle x in the figure below:
BartSMP [9]
First, it's worth noting that angles on a straight line sum to 180°. We can use this information to find out the value of y:
180-52-59=69
y=69°
Another rule is that the angles in a triangle sum to 180° as well. This means that we can now find out x:
63+y+x=180
63+69+x=180
180-63-69=x
x=48°
