Answer:
1. 10 : 24 = 5 : 12 = 20 : 48 = 40 : 96
2. 2 : 3 : 5 = 4 : 6 : 10 = 8 : 12 : 20
The exact answer is 12 root 2, but you can also say approximately 17.
I got this by finding the square root of 369, and then 81. After finding these values, you get the equation...
a^2 + 9^2 = 369
a^2 + 81 = 369
a^2 = 288
And then I just found the square root of 288
Answer:
-1/100
Step-by-step explanation:
-(10)^-2
Exponents first
We need to make the negative in the exponent positive, which means move it to the denominator
-1
--------
10^2
-1
---------
100
So you start off with 228 tickets. The listeners got 5 times the amount that the employees got. So the listeners plus the employees equals 228 which is your starting amount. So you have to plug in each answer to the equation 5x + y = 228 , the x being listeners and the y being the employees. You use the answer choice for the x and y and plug them in and solve until your answer becomes true. I hope that explains it as well as my picture
Basically, you move all terms not containing Y to the right side of the equation.
Y=-1.2
