Since this is an isosceles right triangle the sides have equal length. From the Pythagorean Theorem:
h^2=x^2+y^2, where h=hypotenuse, x and y are the side lengths.
Since x=y=s and we are told that h=22 we can say:
2s^2=22^2
2s^2=484
s^2=242
s=√242
s=√(121*2)
s=√(11*11*2)
s=11√2
For example, let's say b=30. If you divide 30 by 10, you get 3(obviously). But if you divide 10 into 30, you get -3.
Answer 110 books
Step-by-step explanation: 22X5=110
Answer:
Step-by-step explanation:
35x + 10 = 190
35x = 190 - 10
35x = 180
x = 180 / 35
Therefore x = 5.14
Okay, so the rate is 1 job / hours, so:
1/3 + 1/7 (This covers both their work rates) = 1/n (n represents the time it take for them to work together)
Get the LCD:
7/21+ 3/21 = 1/n
10/21 = 1/n
Cross multiply:
10n = 21
n = 2.1
It will take them 2.1 hours, or 2 hours and 6 minutes
