Answer:
Step-by-step explanation:
The formula of a volume of a rectangular box:
<em>l</em><em> - lenght</em>
<em>w</em><em> - width</em>
<em>h</em><em> - height</em>
Therefore the dinemsions of thisp prism are:
Step-by-step explanation:
26=r+10
subtract 10 from both sides
26-10=16. 10-10=0
16=r
24. Yes, they are congruent by the AAS postulate/statement
26. 3/4.5 = 5.2/a -> m-e thm. -> mult. POC -> a = 7.8 in.
30. pythagorean thm. -> 2² + b² = 2.5² -> b = 1.5 m
32. a) v = 1/3πr²h -> v = 1/3*3.14*4.5²*6 (6 is found w/ pythagorean thm.) -> v ≈ 127.2 cm³
b) yes, 130 cm³ > 127.2 cm³
33. a) 4.5/r = 2/7 -> 4.5/2 = r/7 -> 15.75 ≈ 15.8 in.
b) due to the cones being similar in shape, all one-dimensional measurements will be the same, thus, it is 2:7.
What number aa is 25% of 64? An equation is a=0.25*64. The solution is a=16. Then check.
64 / 16 = 4. So 16 is the solution.
