<h3>Answer:  36%</h3>

============================================

Explanation:

There are 20 blue cards out of 10+20+25 = 55 cards total.

Divide the 20 over 55 to get

20/55 = 0.363636...

where the "36"s go on forever

So 20/55 = 0.3636 approximately

Move the decimal point over 2 spots to go from 0.3637 to 36.37%

Then round to the nearest percent: 36.37% ---> 36%

The probability of getting a blue card is approximately 36%

George and his dad made some snack mix for their camping trip. To make it, they used 2 cups of mini pretzels, 3/4 cup of peanuts
Tamiku [17]
They had 17/12 ( 17 over 12, or 1 and 5 over 12)
So the fractions have to have the same denominator. 12 is their common denominator. So:
3/4 = 9/12
2/3=8/12

8/12+9/12= 17/12 or 1 and 5/12

11=-5q+1 what dose it equal-5q+1 what dose q equal
S_A_V [24]

Answer:

The answer is q=-2.

Step-by-step explanation:

You must get q by its self so if you subtract 1 to both sides, you'll get 10=-5q. Now you must divide -5 on both sides to get q by its self. Now, you have -2=q.

Find x<br> A. 22√2<br> B. 22<br> C. 11√3/3<br> D. 11√3
mel-nik [20]

Answer

22\sqrt{2}

Step-by-step explanation:

First we gave a name to the side that is common for both triangles, can be Y for example.

Using trigonometric functions we can make a relationship between the two angles that we have and the magnitud of the side.

sin(45)=\frac{11}{Y}  \\ , Because sin(x)= op/hip

cos(60)=\frac{Y}{x} , Because con(x)=ad/hip

Having this equations, we can solve the system and find x

Y=\frac{11}{sin(45)} \\Y=cos(60)*x

we equal Y and solve

\frac{11}{sin(45)}=cos(60)*x\\ x=\frac{11}{sin(45)*cos(60)} \\x=\frac{11}{\frac{\sqrt{2} }{2} *\frac{1}{2} } \\x=\frac{11}{\frac{\sqrt{2} }{4} } \\x=\frac{44}{\sqrt{2} }\\

Then we rationalize

x=22\sqrt{2}

Hope you like it!
