Answer:

√85

Step-by-step explanation:

a² + b² = c²

6² + b² = 11²

36 + b² = 121

b² = 121 - 36

b² = 85

b = √85

Answer:

Hello! The answer is b = \sqrt{85}.

Step-by-step explanation:

To solve this question, we have to use the Pythagorean theorem. We are given one of the legs and the hypotenuse. (The hypotenuse is opposite the right angle).

a^2 and b^2 represent our legs while c^2 represents the hypotenuse.

We have to substitute our values in for a^2 and c^2:

6^2 + b^2 = 11^2

This leaves us with 36 + b^2 = 121

To get b^2 by itself, we have to subtract 36 from both sides:

36 + b^2 = 121

-36             -36


This leaves us with b^2 = 85

To get just b, we have to take the square root:

√b^2 = √85

This leaves us with b = \sqrt{85}.

The number of measles cases increased 13.6 % to 57 cases this year, what was the number of cases prior to the increase? (Express
ELEN [110]

Answer:

The number of cases prior to the increase is 50.

Step-by-step explanation:

It is given that the number of measles cases increased by 13.6% and the number of cases after increase is 57.

We need to find the number of cases prior to the increase.

Let x be the number of cases prior to the increase.

x + 13.6% of x = 57

x+x\times \frac{13.6}{100}=57

x+0.136x=57

1.136x=57

Divide both the sides by 1.136.

\frac{1.136x}{1.136}=\frac{57}{1.136}

x=50.176

x\approx 50

Therefore the number of cases prior to the increase is 50.

I am a rectangle, and my area is 80 square inches. My width is 2 inches shorter than my length. What is my perimeter?
pshichka [43]
Area=l*b=l*(l-2)=80(given)

so, l^2 - 2l =80
   l^2 - 2l - 80=0
   l=10 or -8

l=10,b=10-2=8
perimeter=2(l+b)=2(18)=36

Solve for x. Show your work.
puteri [66]
So, these are actually pretty simple once you learn the equality used to solve for "x" and when to implement this method. You can use this equality to solve for a segment "x" anytime that two secant lines cutting through a circle come from the same point outside the circle. 

Secant: by geometric definition is just a straight line that cuts a curve into multiple pieces.

I did one of them for you hopefully you can use my work for "a" to help you solve for "b".  For a. I got x=7.
