Answer 6

i think i messed up

Answer 7

is it not going to be a decimal

Answer 8

so we can just cancel out one answer

Answer 9

@prowrestler ... since the line joining the tangent the radius is perpendicular therefore in the quadrilateral thus formed..
two anles are 90 degrees and one is 130 degrees

so then u could use the angle sum property of quadrilateral
which states that sum of all the angles of a quadrilateral is 360 degree


here u go u could use this diagram for help

Answer 10

@prowrestler .. try now..

Answer 11

u just explained it soo much easier

Answer 12

so what is the answer...@prowrestler

Answer 27

\(\large \mathbb{Mass = (density) \times ( volume)}\)

Answer 28

read the question, and figure out wat quantities are given

Answer 29

when u goto shop,
the shop owner wud ask u : how many kilograms of sugar you want ?

Answer 30

wat he is asking ?

Answer 31

4,328 cubic meters of helium.

Answer 32

The density of helium is 0.9874 kilograms per cubic meter.

Answer 33

0.9874 is \(density\)

Answer 34

wat about 4328 cubic meters of helium ?
is it \(Volume\) or \(Mass\) ?

Answer 35

is it the volume

Answer 36

yes, Cubic meters, Cubic centimeters all are volumes...
a 500cc motorbike has a cylinder-volume of 500cc

Answer 37

plug that in the formula

Answer 38

where is the formula srr:(

Answer 39

\(\large \mathbb{Mass = (density) \times ( volume)} \)

Answer 40

just multiply the given two quantities

Answer 41

0.9874 * 4328

Answer 42

yes

Answer 43

4273.4672

Answer 44

\(\huge \mathbb{\color{red}{\checkmark}}\)

Answer 45
