A circular hot spring has a diameter of 106 meters. Over time, the diameter of the spring decreases by 2 meters. By how many square meters does the area of the hot spring decrease? Use 3.14 for

Answers

Answer 1

Answer:

The area decreased by 329.7 square meters.

Step-by-step explanation:

For a circle of diameter D, the area is:

A = pi*(D/2)^2

with pi = 3.14

In this case, we start with a circle of D = 106m

Then the initial area is:

A = 3.14*(106m/2)^2 = 8,820.26 m^2

After, the diameter is decreased by two meters, then the new diameter is:

D' = 106m - 2m = 104m

And the new area will be:

A' = 3.14*(104m/2)^2 = 8,490.56 m^2

The change in the area is A - A' = 8,820.26 m^2 - 8,490.56 m^2 = 329.7m^2

The area decreased by 329.7 square meters.

The National Center for Health Statistics reported that of every 1,008 deaths in recent years, 34 resulted from an automobile accident, 202 from cancer, and 358 from heart disease. What is the probability that a particular death is due to an automobile accident

Answers

Answer:

0.0337 = 3.37% probability that a particular death is due to an automobile accident

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

What is the probability that a particular death is due to an automobile accident?

Total of 1008 deaths.

34 resulted from an automobile accident. So

There is a bag of marbles that contain 5 blues, 6 red, 3 black, and 2 yellow marbles. What is the probability that you select a blue marble

Answers

Answer:

[tex]\frac{5}{16}[/tex]

Step-by-step explanation:

1) Find the total number of marbles

5 blue + 6 red + 3 black + 2 yellow

= 16 marbles

2) To find the probability of selecting a blue marble, divide the number of blue marbles by the number of total marbles:

5 blue marbles ÷16 marbles

[tex]= \frac{5}{16}[/tex]

Therefore, the probability of selecting a blue marble is [tex]\frac{5}{16}[/tex].

Avocado Pickers are paid as shown below. What would be the gross
earnings for a worker that picks 1,108 avocados?
1 - 500 Avocados $0.10 each
501 - 700 Avocados $0.14 each
Over 700 Avocados $0.18 each

Answers

Answer:

The avocado picker earned $151.44.

Step-by-step explanation:

Given that avocado pickers are paid $ 0.10 if they collect from 1 to 500 avocados, $ 0.14 if they collect from 500 to 700 and $ 0.18 if they collect more than 700, to determine what would be the gross earnings for a worker that picks 1,108 avocados, the following calculation must be done:

1,108 - 700 = 408

700 - 500 = 200

500 x 0.10 + 200 x 0.14 + 408 x 0.18 = X

50 + 28 + 73.44 = X

151.44 = X

Therefore, the avocado picker earned $151.44.

What is the height, in yards, of a cylindrical water tank that holds 1,884 cubic yards of water and has a diameter of 120 feet? Be sure to convert so you are using like units.

Answers

Answer:

The height of the tank is 0.5 yards.

Step-by-step explanation:

To determine what is the height, in yards, of a cylindrical water tank that holds 1,884 cubic yards of water and has a diameter of 120 feet, knowing that the volume of a cylinder is equal to pi multiplied by the radius squared, multiplied by the height, the following calculation must be done:

1 foot = 0.3333 yards

R = Diameter / 2

R = 120/2 = 60

3.14 x 60 ^ 2 x H = 1,884

3.14 x 3,600 x H = 1,884

3.14 x 1,200 x H = 1,884

3.768 x H = 1.884

H = 1,884 / 3,768

H = 0.5

Therefore, the height of the tank is 0.5 yards.
