In aboard game you determine the number of spaces you msy move by spinning a spinner and rolling a die. The spinner has three regions: half of the spinner is marked"5" and the other half is equally divided between "10" and "20". The six faces of the die show 0,0,1,2,3,and 4 spots. When its your turn, you spin and roll, adding the numbers together to determine how far you may movefind the mean and standard deviation of the spiner results after you create a probability model for the outcome on the spinner

Step-by-step explanation:

Two solutions of different concentrations of acid are mixed creating 40 mL of a solution that is 32% acid. One-quarter of the solution is made up of a 20% acid solution. The remaining three-quarters is made up of a solution of unknown concentration, c.Which equation can be used to determine c, the unknown concentration?

Answers

Taking the 3 solutions as 3 different terms, we can create an equation as follows:

Solution 1 : 10mL with 20% acid
Solution 2 : 30mL with x% acid
Solution 3 : 40mL with 32% acid

Since solution 1 + solution 2 = solution 3, let us substitute the given values we have:

10(0.2) + 30(x) = 40(0.32)
2 + 30x = 12.8

To solve for the unknown concentration x, we subtract 2 from both sides:
2 + 30x - 2 = 12.8 - 2
30x = 10.8

Dividing both sides by 30:
30x/30 = 10.8/30
x = 0.36

Therefore the unknown solution is 36% acid.

Answer:

Therefore the unknown solution is 36% acid.

You deposit $3000 in a savings account that earns 2.9% annual interest compounded monthly. You also save $80 per month in a safe at home. Write a function for the total amount of money saved C(t)=b(t)+h(t), where b(t) represents the balance of your savings account and h(t) represents the amount in your safe after t years. Round any decimals to three decimal places.
