The answer should be x=4/3
Answer:
150 mm^3
Step-by-step explanation:
The formula of a pyramid is
V=1/3(Bh)
The formula for a rectangle is
V=(Bh)
They both have the same Bh, so because the formula of a pyramid states that it's 1/3 of Bh, and 1/3 of Bh = 50, the volume of a whole Bh is 150mm^3.
Hope this makes sense
Parallel lines have the same slope.
'a' is the only choice that has the same slope (-5/4)
as the line in the question.
306% of 25
= (306/100) * 25
= 3.06 * 25
= 76.5
I assume you mean one that is not rational, such as √2. In such a case, you make a reasonable estimate of it's position, and then label the point that you plot.
For example, you know that √2 is greater than 1 and less than 2, so put the point at about 1½ (actual value is about 1.4142).
For √3, you know the answer is still less than 4, but greater than √2. If both of those points are required to be plotted just make sure you put it in proper relation, otherwise about 1¾ is plenty good (actual value is about 1.7321).
If you are going to get into larger numbers, it's not a bad idea to just learn a few roots. Certainly 2, 3, and 5 (2.2361) and 10 (3.1623) shouldn't be too hard.
Then for a number like 20, which you can quickly workout is √4•√5 or 2√5, you could easily guess about 4½ (4.4721).
They're usually not really interested in your graphing skills on this sort of exercise. They just want you to demonstrate that you have a grasp of the magnitude of irrational numbers.
