A. V = 1/12 s ^3
B. V=1/6 s ^3
C. V=1/3s ^3
D. V=3s³
E. V=6s³

Answers

Answer:

V = (s^3)/6  (Answer B )

Step-by-step explanation:

If the length of a side of the base is s, then the height of the pyramid is half that, or s/2.

The volume of a pyramid with a square base and base side length S and height H is V = (1/3)(S^2)(H).

In this case, the formula is V = (1/3)(s^2)(s/2), or V = (s^3)/6  (Answer B)

If you receive a 25% MARKUP on an item costing $60.00, how much money do you pay in total?

Answers

Answer:

Money Paid in Total  = $45

Step-by-step explanation:

Firstly, the term Mark-up refers to the amount added to the cost price to cover the overheads and realize a profit.

A mark-up percentage is a percentage (%) that is used as a basis to determine the mark-up value.

Given

Cost of an Item = 60$

Markup % = 25% on cost

Hence, Mark up in $ = 60$*25%

                                   = 15$

Therefore, Actual cost of an item = Cost of an item - Mark up on Item

                                                        = 60$ - 15$

                                                         = 45$

The community centre has an L-shaped swimming pool that is 10 feet deep. What is the volume of the pool

1200

1040

640

880

What is volume?

Volume is defined as the space covered by any solid body in the three-dimensional plane.

We know that the total volume of the pool is the sum of the volume of two rectangular prisms.

One is a rectangular prism with dimensions 20ft.×10ft.×4ft.

and the other rectangular prism has dimensions: 6ft.×4ft.×10ft.

Hence, the volume of a first rectangular prism is:

20×10×4=800 cubic ft.                      

The volume of a second rectangular prism is:

6×4×10=240 cubic ft.                    

Hence, the total volume of the pool is:

800+240=1040 cubic ft.                

Therefore the total volume of the pool is 1040 cubic ft. The correct answer is option B.

A scientist studying insects start with a population of 10. the population triples every hour. how many insects wil there be after 20 minutes​

Answers

The question is asking you to understand that a population which is raised by a common ratio over a certain time period follows an exponential pattern. See:

After 1 hour, the population is 3*10

After 2 hours, the population is 3*3*10

After 3 hours, the population is 3*3*3*10

.....

This can be generalised as a function of t, the time in hours:

f(t) = (3^t) * 10

Since the function determines the population at a given time, it is more prudent to replace f(t) with P, the population after time t:

P = (3^t) * 10

Since 20 minutes is equal to (1/3) hours, t can be substituted for (1/3) in order to calculate the population size after 20 minutes:

P = (3^(1/3)) * 10 = 14.4224957031 ≈ 14

Therefore the population after 20 minutes is 14.

A 400 second song is divided into three parts the beginning the middle and the end the beginning is one sixth as long as the end

Answers

The beginning, middle and end part of the song is 40, 120 and 240 seconds respectively

How to find equation of the unknown

let

x = end partBeginning = 1/6xMiddle = 1/2xTotal = 400 seconds

x + 1/6x + 1/2x = 400

(6x+x+3x) / 6 = 400

10/6x = 400

x = 400 ÷ 10/6

x = 400 × 6/ 10

= 2400 / 10

= 240 seconds

Therefore,

End part = x

= 240 seconds

Beginning = 1/6x

= 1/6 × 240

Find the equation of the line parallel to y = 2x - 4 that runs through the point (-2, 4).
y = 1/2x + 4

y = 2x + 8

y = 2x + 4

y = -1/2x + 8

Answers

Answer:

y = 2x + 8

Explanation:

Equation: y = 2x - 4

Comparing it with slope intercept form "y = mx + b" where 'm' is slope and 'b' is y-intercept. This function has slope: 2 and y intercept of -4

Parallel lines has same slope.

Passes through (-2, 4)

[tex]\sf y - y_1 = m(x - x_1)[/tex]

[tex]\sf y - 4 = 2(x - (-2))[/tex]

[tex]\sf y - 4 = 2(x + 2)[/tex]

[tex]\sf y = 2x + 4 + 4[/tex]

[tex]\sf y = 2x + 8[/tex]

Answer: y = 2x + 8

Step-by-step explanation:

This is a fairly simple problem. I hope this helps!

So, to find a line parallel, it's simple, and it only requires that for the other line to have the same slope and a different y-intercept (or same "m" and different "b" in the equation y = mx + b).

To find a line parallel to a point is slightly harder, but don't worry, I'll teach you how.

To do this, we have to recognize the point. The point given is (-2, 4) where -2 is the x-value and 4 is the y-value. Remember, points always go by (x, y).

So, we set y to 4, and we set x to -2.

When testing out lines that are parallel to a point, you must always be careful that you end up with the same value. Such as 4 = 4 or 8 = 8, etcetera.

We get:

4 = 2 × (-2) + 8

Simplifying, we get:

4 = -4 + 8

Adding -4 to 8, we get 4:

4 = 4

Thus, y = 2x + 8 is parallel to the point (-2, 4)

Answers

Answer:

311  1/9 or 311.11 m

Step-by-step explanation:

Let the total distance be x.

We have:

9/10 of x is 280 m.

Set this as equation and solve for x:

(9/10)x = 280x = 280 ÷ 9/10x =  280 × 10/9x = 2800/9 = 311  1/9 or 311.11 m

Total distance from the park to the station is approximately 311 m.

Let that be d
