Answer:
35
Step-by-step explanation:
5 times 6 is = 30
so....
5 time 7 =35
Answer:
0.25
Step-by-step explanation:
Since, in the question , it is not mentioned that two balls of any specific colour,
the probability of getting two balls is: 
Let x = amount of 45% antifreezeLet y = amount of 70% antifreeze EQUATION 1: x + y = 150 (total of 150 gallons mixed) EQUATION 2: .45x + .75y = .55(x + y) Simplify and solve the system of equations Multiply second equation by 100 on both sides to remove the decimals 45x + 75y = 55(x + y) Combine like terms 45x + 75y = 55x + 55y 45x - 55x + 75y - 55y = 0 -10x + 20y = 0 Now we have the following system of equations: x + y = 150 -10x + 20y = 0 Multiply the first equation by -10 to get opposite coefficients for x; add the equations to eliminate x 10x + 10y = 1500 -10x + 20y = 0 ------------------------------ 30y = 1500 Solve for y 30y = 1500 y = 50 Since the total mixed gallons is 150, x = 150 - 50 = 100 So we need 100 gallons of the 45% antifreeze and 50 gallons of the 70% antifreeze
Profit = (selling price x number of units) - expenses in this case, the selling price is $855, number of units is 250, and the expenses are $6,780 So, Profit = ($855 x 250) - $6,780 = $206,970 That number times 15% (decimal = 0.15) will be the salary of the CEO So, $206,970 x 0.15 = $31,045.50
SO C.
If 3 cups is 20% of the whole mixture, then you multiply both numbers by 5 to find the total amount of juice. 3•5=15 cups of juice
