15% = 0.15
multiply the bill ( 42.00) by 0.15 for the amount of tip
42.00 * 0.15 = 6.30
the tip = $6.30
1 meter = 100 cm
16×100=1600
1600-1000=600
Answer:
V = 10,240mm^3
Step-by-step explanation:
The volume of pyramid is given by the following formula:
(1)
b: base of the pyramid = (32mm)^2
h: height
Thus, it is necessary to find the value of h, by using the Pitagoras's theorem, one half of the base and the slant height (which forms a rectangle triangle with h):

by replacing in (1) you obtain:

hence, the volume is 10240mm^3
15.38. 7, the number in the hundredths place, is turned into 8 due to the following digit, 5. Since it is equal to the minimum, 5, the previous number is rounded up.
