Answer:
2x - 11 = 5
Step-by-step explanation:
x can be any variable
Answer:
Your answer is <em>8.06</em>.
Step-by-step explanation:
Since you're finding the hypotenuse of the triangle through Pythagorean theorem, you need to use the formula:
a² + b² = c²
Here, you have to remember that x is the same as c in the formula. c is the hypotenuse and x.
a is going to be your smallest leg, so in this case a = 4.
b is going to be your longest leg, so it is b = 7.
Now, you don't know what c yet is so you simply write it as:
4² + 7² = c²
Do the exponents.
16 + 49 = c²
Add.
65 = c²
Now you need to get the exponent away from the c. To do that, all you have to do is square root both sides.
√65 = √c2
Once you do that, you have your answer!
<u>8.0622577483 = c</u>
Now just simplify and you're done :)
<u>8.06</u>

Might sound hard now but you'll get the hang of it.
There is 150% increase in the number of volunteers.
Step-by-step explanation:
Given,
Old number of volunteers = 20
New number of volunteers = 50
Change = New value - Old value
Change = 50 - 20 = +30
The positive sign indicates the increase.
Percent increase =
