Find the volume of a right circular cone that has a height of 11.9 ft and a base with a radius of 16.3 ft. Round your answer to the nearest tenth of a cubic foot.

Answers

Answer:

3311.36ft^3

Step-by-step explanation:

Given data

Height h= 11.9ft

Radius=16.3ft

The expression for the volume of a cone is given as

Volume= 1/3πr^2h

substitute

Volume=1/3*3.142*16.3^2*11.9

Volume= 1/3*3.142*265.69*11.9

Volume= 1/3*9934.095962

Volume=3311.36ft^3

Hence the volume is 3311.36ft^3

Consider a student’s work in determining the solution set of x > 2(y – 1)^2 – 2.

Test point: (2.25, 1.25)

x > 2(y – 1)^2 – 2

2.25 > 2(1.25 – 1)^2 – 2

2.25 > 2(0.25)^2 – 2

2.25 > 2(0.0625) – 2

2.25 > 0.125 – 2

2.25 > –1.875

Conclusion: The point (2.25, 1.25) satisfies the given inequality.

Solution set:

Which element, if any, shows an error in the student’s work?

There are no errors.
The conclusion statement is incorrect.
The graph of the solution set is incorrect.
The substitution of x and y values is incorrect.

Answers

Answer:

C. The graph of the solution set is incorrect.

Step-by-step explanation:

Solution is right, properly substituted x- and y-values, no mistakes. Conclusion is right, the point within the solution set. The only mistake is the graph, with > sign the line of the graph is not included into solution, therefore should be dotted.

There are no errors.

Incorrect (the graph)

The conclusion statement is incorrect.

The graph of the solution set is incorrect.

Which ordered pair is a solution of y = x - 4?

A: (3,-7)

B: (-3,-7)

C: (3,7)

D: (-3,7)

Answers

Answer:

The correct answer is (-3,-7). This is because you can plug it in and the two sides are equal to each other. When you plug -3 in for x, you subtract for from it and get -7 since the y term is -7 the answer is -7=-7, thus (-3, -7) is the answer.

statement about the completion times is most likely to be true?
Of these students, 25% complete the test in 110 minutes or less.
B. Of these students, 50% complete the test in 110 minutes or less.
C. Of these students, 75% complete the test in 127 minutes or less.
D. Of these students, 75% complete the test in 144 minutes or less.

Answers

Answer:

Step-by-step explanation:

half of IQR is 17

110 + 17 = 127 (this represents the 3rd quartile)

110 - 17 = 93 (this represents the 1st quartile)

The 3rd quartile represents 75% of the data so 75% of the students complete the test in 127 minutes or less
