Can someone help me with the volumes of pyramids please for a brainless and points​

Mathematics
1 answer:
Rufina [12.5K]3 years ago
6 0

Answer:

Step-by-step explanation:

Volume of a pyramid = (l×b×h)/3

V = 128cm^3,

l = 8cm

b = 8cm (/because is a square base)

Substituting this values

128 = (8×8×h)/3

Cross multiply

128×3 = 64h

384 = 64h

Dividing through by 64

h = 384/64

h = 6cm

Height is 6cm

A smaller square park has an area 3600 square meters what is the length of one side of the park
rjkz [21]

Squares have equal side lengths, so that is why the question is only asking for one side length.

The area of a square is calculated using the formula s^2, where s stands for a side of the square.

To find the length of one side of the park, you can take the given area (3,600 m^2) and square root it. This would give you the length of one side of the square park.

√3,600 = 60

The length of one side of the park is 60 meters.

We can find the length of DE using the Pythagorean Theorem:
prohojiy [21]
What's the difference between A) and C)??
There should be an E) because the correct answer would be in either of these forms:
{DE}^{2}  =  {(4 - 1)}^{2}  +  {(1 - 3)}^{2}  \:  \: or \\  DE  =  \sqrt{( {3}^{2}  +  {2}^{2} )} \:   \: or \\  {DE}^{2}  =  {(4 - 1)}^{2} +  {(3 - 1)}^{2}

Answer:

  WX = 33

  (x, y) = (2, 10)

Step-by-step explanation:

The hash marks tell you WX is a midline, so has the measure of the average of the two bases.

  WX = (PQ +SR)/2 = (27 +39)/2 = 66/2

  WX = 33

__

The hash marks also tell you ...

  PW = WS

  y +4x = 18 . . . . . . substitute the given expressions

and also

  QX = XR

  2y +x = 22 . . . . . substitute the given expressions

__

If you solve the first equation for y, you get ...

  y = 18 -4x

Substituting that into the second equation gives ...

  2(18-4x) +x = 22

  36 -7x = 22 . . . . . . . simplify

  14 = 7x . . . . . . . . . . . add 7x-22 to both sides

  2 = x . . . . . . . . . . . . divide by 7

  y = 18 -4(2) = 10 . . . find y using the above relation

The values of x and y are 2 and 10, respectively.

__

My favorite "quick and dirty" way to solve a set of linear equations is using a graphing calculator. It works well for integer solutions.
