Your Answer is:

n>21

In other words it could be said as "a NUMBER Exceeds 21" where the key words are Number Exceed and the number 21. Where N=Number Exceed=> and 21 is less than a number.

Answer:

1.

a rectangular prism is simply a block. it has length, width and height. and similar to the area of a rectangle (length×width) we get as volume length×width×height.

other than that we only need to consider that a volume always has cubic units (like cm³, m³, ft³, ...).

the volume of a cylinder is again ground area times height, when we imagine the cylinder to stand on it circular side.

and the states standard formula (hi, internet !) for the volume of a cylinder is pi×r²×height

so, we have 75×20×14 = 21,000 cm³

and pi×75²×120 = pi×5625×120 = 2,120,575 cm³

so, the cylinder has a much bigger volume.

3.a.

the standard formula for the volume of a pyramid (hi, internet !) is length×width×height/3

the diagram means that it is a square pyramid (the ground area is a square). therefore all sides of the ground area are of equal length. length = width

so, we have 64×64×40/3 = 54631.333... m³

3.b.

as the description says, 5000 people fit in, so, to find how much volume is there available per person, we need to divide the volume by 5000.

54631.333... / 5000 = 10.923 m³

Step-by-step explanation:

and again, you need only to search the formulas on the internet, and then calculate this with the given numbers yourself, and you will be much faster than paying things here and waiting for answers and copy/pasting things.

again, there is practically nothing to explain, just to use the standard formulas and the calculator. what's the problem ?

I will gladly explain to you concepts you have not understood (that is the point of Brainliest). but I and others here are not your personal slaves to do your work for you.

the perimeter of a rectangle is twice the sum of its length and its width. The perimeter is 16 meters and its length is 2 meters
Olegator [25]
You'd do 16 times 2 since the length is TWICE as much as 16. So 16x2=32x2=64

Answer:

358.01

Step-by-step explanation:

3 x 10^2 +5 x 10^1 +8 x 10^0 +1 x 1/10^2

3 x 100 + 5 x 10 +8 x 1 +1 x 1/100

300 +5 x 10 +8 x1 +1 x 1/100

300 + 50 +8 x1 +1 x 1/100

300 +50 +8 +1 x1/100

300 +50 +8 +1/100

358 +1/100

35801/100

1. Find the 8th term of the following linear sequences.
Bond [772]

We know the formula,

t =n =ar

n−1

Here n=8

Common ratio =−2 and first term =a=−6

t =8

=(−6)×(−2)

8−1

t =8

Use this formula

=(−6)×(−2)

7 t= 8

=768
