Answer:
(x + 1 s 1) n (x + 12 1)
(x +1<1) n (x + 1 > 1)
Step-by-step explanation:
Just simplify each the statements.
Then compare and and see if the statements are contradictory and therefore FALSE, if so, then there is no solution.
(x + 1<-1) n (x + 1< 1)
(x <-2) n (x < 0) which is true, so there is a solution.
(x + 1 s 1) n (x + 12 1)
this doesn't make sense so there is no solution.
(x +1<1) n (x + 1 > 1)
(x < 0) n (x > 0)
This is not possible, the statements are contradictory and therefore FALSE, so there is no solution.
Answer:
9 gallons of water per minute
Step-by-step explanation:
First identify what you know:
1) The pipe was flowing water for eight minutes.
2) In that eight minutes, 72 gallons of water came out.
So, if 72 gallons of water came out in eight minutes, how many gallons flowed out in a single minute? Well, assuming that the flow rate was consistent, then simply divide the total number of gallons that flowed out, by the number of minutes the pipe was open!
72/8 = 9
The pipe released 9 gallons of water per minute, thus resulting in 72 gallons of water in 8 minutes!
Hope this helps! :)
Answer:a
Step-by-step explanation:
Cause boys is 2/5 and girls are 3/5
Use the Pythagorean theorem.
If x is a hypotenuse, then we have:
![x^2=4^2+5^2\\\\x^2=16+25\\\\x^2=41\to x=\sqrt{41}](https://tex.z-dn.net/?f=x%5E2%3D4%5E2%2B5%5E2%5C%5C%5C%5Cx%5E2%3D16%2B25%5C%5C%5C%5Cx%5E2%3D41%5Cto%20x%3D%5Csqrt%7B41%7D)
If x is a leg, then we have:
![x^2+4^2=5^2\\\\x^2+16=25\ \ \ \ |-16\\\\x^2=9\to x=\sqrt9\to x=3](https://tex.z-dn.net/?f=x%5E2%2B4%5E2%3D5%5E2%5C%5C%5C%5Cx%5E2%2B16%3D25%5C%20%5C%20%5C%20%5C%20%7C-16%5C%5C%5C%5Cx%5E2%3D9%5Cto%20x%3D%5Csqrt9%5Cto%20x%3D3)
