Answer:
it is a convenience sample
Step-by-step explanation:
The unit measurement of the a volume in mm is mm³(millimetres cube.)
<h3>How to find volume ?</h3>
Volume is is defined as the space occupied within the boundaries. The objects are usually solid objects.
The volume of a 3 dimensional figure is the product of the base area and the height.
Therefore, the units of volume is measured in cubic units.
The volume of a prism with side lengths measured in millimetres is 20.
Therefore, the measurement can be represented as follows:
20 mm³

Answer:
300 in³
Step-by-step explanation:
By definition, volume of a pyramid,
= (Base Area x height ) / 3
= (90 x 10) / 3
= 900/3
= 300 in³
Answer:
(-4,9)
Step-by-step explanation:
To solve the system of equations, you want to be able to cancel out one of the variables. In this case, it'd be easiest to cancel out the x variables. To do this, you'll want to multiply everything in the first equation by 2 (2(x-5y=-49)=2x-10y=-98). Then, you can add the two equations together. 2x and -2x will cancel out, so you'll be left with -11y=-99. Next, solve for x by dividing both sides of the equation by -11, which will give you y=9. This is your y-coordinate! At this point, you're halfway to the answer as you just need your x-coordinate. It's not too difficult to find the x-coordinate, since you just substitute 9 into one of the equations. It doesn't matter which one you choose as you should get the same answer with both. I usually substitute the y-value into both equations, though, just to make sure I'm correct. Once you put the y-value into the equations, you should get x=-4 after solving it. :)
A percent is a number out of 100, so you'd want to multiply the denominator to get 100. In this case, 25 would have to be multiplied by 4 to get 100. To keep the fractions equal to each other, you have to multiply the numerator by the same thing. 2*4=8. Therefore, your fraction would be 8/100 or 8%
