Answer:
14.7
Step-by-step explanation:
a^2+b^2=c^2
15^2+b^2=21^2
225+b^2=441
subtract 441-225=216
square root of 216 = 14.6969384567
= 14.7
In one month she completed 5 paintings, so in 6 month she completed 6 * 5 = 30 paintings.
38 - 30 = 8 - that's how many paintings she's still about to complete.
If she can do 5 paintings in one month, she'll do 8 paintings in 1 3/5 months. If we assume that month has 30 days, she'll probalby need one month and 18 days to do it (because 3/5 from 30 is 18).
Step-by-step explanation:
2/8 = u/12
cross multiply and we get:
24= 8u
u = 3

Answer:
s=22.17
Step-by-step explanation:
v/r=u/s
18/19=21/s
18s=21(19)
18s=399
18s/18=399/18
s=22.17
Answer:An integer (from the Latin integer meaning "whole") is colloquially defined as a number that can be written without a fractional component. For example, 21, 4, 0, and −2048 are integers, while 9.75, 512, and √2 are not. ... ℤ is a subset of the set of all rational numbers ℚ, which in turn is a subset of the real numbers ℝ.
