Arturo's family hires 3 painters. Each painter charges $50 per hour. Arturo's family represents the charge for x hours of painti
PIT_PIT [208]

Answer:

D

Step-by-step explanation:

So if Arturo's family hires 3 painters for $50 an hour each, how much do they spend?

X= Charge for number of number of hours

Now let's say that each of the painters worked only <u>one </u> hour each.

That would be take a long time to add up so you multiply.

$50 x 3

In other words it's $50 + $50 + $50.

$50 x 3 = $150

Now X stands for the amount of money paid to each artist. In this case, X= $50. So we already figured out X. X is $50. It is a mistake to add the X at the end of the answer because X is already there in a numerical form. So the answer is D, $150.

A heavy metal sphere
GaryK [48]

Answer: the height of the water after the sphere is placed in

it is 33.33 cm

Step-by-step explanation:

The cylinder is called a right circular cylinder because its height make a right angle with its base. The formula for determining the volume of the cylinder is expressed as

Volume = πr^2h

Where

π is a constant whose value is 3.14

r represents the radius of the cylinder.

h represents the height of the cylinder.

From the information given,

r = 10 cm

h = height of water in the cylinder = 20 cm

Volume of water in the cylinder before the sphere was placed in it would be

V = 3.14 × 10^2 × 20 = 6280 cm^3

The formula for determining the volume of the sphere is expressed as

Volume = 4/3 πr^3

V = 4/3 × 3.14 × 10^3 = 4186.67cm^3

Total volume of the sphere and the cylinder = 6280 + 4186.67 = 10466.67 cm^2

To determine the new height of the water,

10466.67 = 3.14 × 10^2× h

h = 10466.67/314 = 33.33 cm

d. Of all possible samples of the same size, 20.79 percent will result in 85 percent of adult sea turtles on the beach being females.

Step-by-step explanation:

Hypothesis testing is conducted to test an observation against the null hypothesis. P-value is calculated to determine whether to accept or reject the null hypothesis. In the given case the p-value is 0.4158 which means null hypothesis is true.
