A Pyramid And A Cone Are Both 8 Centimeters Tall And Have The Same Volume.What Statement Must Be True

Answers

Answer 1

Answer:

D. The horizontal cross-sections of the prisms at the same height must have the same area.

Step-by-step explanation: I dont know what the guy above is saying but this is the right answer

Answer 2

Since it is given that both prisms have the same height and volume, the answer is option D. The horizontal cross-sections of the prisms at the same height  must have the same area.

A solid figure is one which has surface area and volume. Examples are prisms, cube, cuboid etc. Thus cones and pyramids are solid figures.

From the given question,

Volume of a cone, V = [tex]\frac{1}{3}[/tex][tex]\pi r^{2} h[/tex]

where r is its radius, and h its height

also,

Volume of a pyramid, V = [tex]\frac{1}{3}[/tex] lwh

where l is its length, w is the base width and h is its height.

Given that: i. volume of cone = volume of pyramid

                  ii. height of cone = height of pyramid

Then,

[tex]\frac{8}{3}[/tex][tex]\pi r^{2}[/tex] = [tex]\frac{8}{3}[/tex]lw

[tex]\pi r^{2}[/tex] = lw

Thus it can be deduced that at the same height, the horizontal cross section of the prisms have equal area. So that option D is the appropriate answer to the given question.

Answer: 9,600

Step-by-step explanation:

I could possibly did wrong but I shall explain this none the less. I first knew that 10% of 16,000 was 1,600. So then I just timed that by four getting 6,400. I then did 16,000-6,400 getting $9,600. Sorry if I’m wrong

Answer:

$9600

Step-by-step explanation:

10% of 16,000 = 1600

1600*4= 6400

16,000-6,400

Can you conclude from the figure that ABC is similar to DEF? Explain.​

Answers

Answer:

Yes, we can conclude that Triangle ABC is similar to triangle DEF because the measures of the 3 angles of both triangles are congruent.

Step-by-step explanation:

We have the measure of 2 angles from both triangles, and we know that triangles have 180°, so we can solve for the measure of the third angle for both triangles.

Triangle ABC:

Measure of angle A= 60°

Measure of angle C= 40°

Measure of angle B = 180°- (measure of angle A + measure of angle C) = 180° - (60° + 40°) = 80°

Triangle DEF

Measure of angle E= 80°

Measure of angle F= 40°

Measure of angle D= 180° - (measure of angle E + measure of angle F) = 180° - (80° + 40°) = 60°

The measures of the angles in Triangle ABC are: 60°, 40°, and 80°.

The measures of the angles in Triangle DEF are: 60°, 40°, and 80°.

Since the measure of 3 angles of the two triangles are the same, we know that the two triangles are similar.

After that incident, the Civil defense team decided to buy new trucks with ladders higher than 100 feet. They found 2 different trucks with the same height of ladders. The first truck costs $145,000 and will cost $0.31 per mile traveled based on the current gas prices. The second truck will cost $160,000 but gets better gas mileage, costing $0.27 per mile. They need to decide which truck is the best deal.

Answers

Answer:

the first truck

Step-by-step explanation:

the cost difference between the first truck and the second truck = $160,000-$145,000 = $15,000

the difference of gas cost between the first truck and the second truck = $0.31 - $0.26= $0.05 per mile.

so,

I think, this is a very significant number of truck cost compared with gas cost

for the best deal, the first truck is the best choice.

how to solve y=-5/2x+4, Y=-1 using substitution
(i need the steps not just the answer)​

Answers

Answer:

Step-by-step explanation:

- Since y = -1, we will substitute the y variable in the equation for -1.

 -1 = -5/2x + 4

- Take away 4 from both sides in order to find out what x equals so we can substitute it.

 5 = -5/2x

- turn it into a positive by multiplying each side by -1.

 -1(-5 = -5/2x) =

 5 = 5/2x

- Divide each side by 5.

 1 = 1/2x

- Multiple both sides by 2.

2 = x

- Substitute the variables.

x = 2

y = -1

-1 = -5/2(2) + 4

How to find the axis of symmetry of a quadratic function?

The axis of symmetry is a line of the form x = a, such that it divides the parabola in two halves.

Particularly, the axis of symmetry passes through the vertex, so the x-value of the vertex is equal to the value of the axis.

Then we only need to find the x-value of the vertex, remember that for a quadratic:

[tex]y = a*x^2 + b*x + c[/tex]

The vertex is at:

[tex]x = -b/2a[/tex]

Then in our case, the vertex is at:

[tex]x = -12/(2*-2) = -12/-4 = 3[/tex]

So the axis of symmetry is x = 3, then the correct option is C.
