Answers

Answer 1

Answer:

The volume of the cone is 4840 cubic ft if the diameter of the base is 34 feet and the height is 16 feet option (C) is correct.

What is a cone?

It is defined as a three-dimensional shape in which the base is a circular shape and the diameter of the circle decreases as we move from the circular base to the vertex.

$\rm V=\pi r^2(h)/(3)$

Volume can be defined as a three-dimensional space enclosed by an object or thing.

It is given that:

A pile of tailings from a gold dredge is in the shape of a cone.

The diameter of the base is 34 feet and the height is 16 feet.

As we know,

The volume of the cone is given by:

$\rm V=\pi r^2(h)/(3)$

r = 34/2 = 17 ft

h = 16 feet

Plug the above values in the formula:

$\rm V=\pi (17)^2(16)/(3)$

After solving:

V = 1541.33π cubic feet

Take π = 3.14

V = 1541.33(3.14) cubic feet

V = 4839.78 ≈ 4840 cubic ft

Thus, the volume of the cone is 4840 cubic ft if the diameter of the base is 34 feet and the height is 16 feet option (C) is correct.

Answer 2

Answer:

Answer:

C: $V=4840 (2 s.f.)$

Step-by-step explanation:

The formula for the volume of a cone is:

$V= (1)/(3) \pi r^2h$

Therefore,

$V=(1)/(3)* 3.14*((34)/(2))^2* 16\n\nV=4840 (2 s.f.)$

A movie was shown 6 times every day from November 24 through December 19. How many times was the movie shown in all? (Note: The month of November has 30 days.)

Answers

Answer:

156 times

Step-by-step explanation:

Given: A movie was shown 6 times every day from November 24 through December 19.

To find: The number of times the movie shown in all.

Solution:

To find the number of times the movie shown in all, we need to first find the number of days the movie is shown.

So, we have to find the number of days from November 24 through December 19.

Number of days the movie is shown in November is 7 days.

In December the movie is shown for 19 days.

So, we get the movie is shown for 26 days in all.

It is given that, each day the movie is shown 6 times.

So, to find the total number of times the movie is shown we need to multiply 26 and 6.

Therefore, we get

number of times movie shown $=26*6=156$

Hence, the movie is shown 156 times.

Answer:

Answer: A. 138 times

How?

During that time period there were 23 days so 23 multiplied by the amount of times played per day (6)

You get the answer 138

A 1400 sq ft house is advertised for sale at a price of $125,000. What is the cost per square foot?

Answers

The answer is $89.28.

Let's use the proportion for this:
If 1400 ft² costs $125,000, 1 ft² will cost x:
1400 ft² : $125,000 = 1 ft² : x

Now, crossing the products:
x · 1400 ft² = $125,000 · 1 ft²
x · 1400 = $125,000
x = $125,000 ÷ 1400
x = $89.28

Therefore, 1 square foot costs $89.28.

If you would like to know the cost per square foot, you can calculate this using the following steps:

1400 sq ft house ... $125,000
1 sq ft ... $x = ?

1400 * x = 125,000 * 1
1400 * x = 125,000
x = 125,000 / 1400
x = $89.29

The correct result would be $89.29.

D) -3

Answers

If you would like to know the coefficient of x, you can calculate this using the following steps:

(18x^3 + 12x^2 – 3x) / (6x^2) = (6x^2 + 4x - 1) / (2x) = 3x + 2 -1/(2x)

The correct result would be A) 3.
