Answer:
None
Step-by-step explanation:
Assuming you mean sides of a right triangle, we can use the Pythagorean theorem (A^2 + B^2 = C^2)
We have A and B, so we can plug those into the equation.
(16)^2 + B^2 = (14)^2
(16)^2 is 256 and (14)^2 is 196. Plug those in.
256 + B^2 = 196
Get rid of the 256 by subtracting.
B^2 = 196 - 256
B^2 = -60
√B^2 = √-60
You can't take the square root of a negative number, so the solution is not possible. We can confirm because C cannot be bigger than A or B.
Answer: 4
Step-by-step explanation:
1. Subtract 2 from both sides.
5y=22 -2
This equals 5y=20
2.Divide by 5 on each side. That gets 4.

Answer:
Step-by-step explanation:
If we let x = the amount of 5% solution and y = the amount of pure alcohol, we can set up that
.05x+y is the amount of alcohol in our resulting mixture, and x+y is the total amount in our resulting mixture (which we know is 380)
so we also know that:
(.05x+y)/380 = .6
If we simplify this we come up with:
.05x+y=228
and we know x+y=380
If we solve this as a system of equations, we will find that:
x=160 ml
y=220 ml
Answer:
No
Step-by-step explanation:
No. You can see why if you remove the brackets.
y=x^2 - 3x.
A linear function must have x and y with powers of 1. Also it can't something like x^2 - y^2 = 5
x^2 - y^2 = 0 is the only exception I can think of, but that really is a system of equations. If you graph it. you get two equations which cross at 0 and nowhere else.
Answer:
4/9 probability you will get an even number
Step-by-step explanation:
The theoretical probability of spinning an even number is 4/9, since there are 4 even numbers in the spinner
