First, we need to convert 10 1/2 into eighths. We have 84 eighths. Next, we divide 84 by 7, which leads us to 12. There will be 12 se tions
The answer for this equation is 10 gallons of water
C. Y = -10x -4 as this is the largest slope with a slope of -10/1
Answer:
d: 729/64
Step-by-step explanation:
Plug-in the variables
The 10 tons should have 37.9% cement.
Let the 25% mixture be x tons
Then the 68% mixture will be (10 -x) tons.
Using formula for mixtures:
Let p for percentage and w for weight in tons.
p₁w₁ + p₂w₂ = pw
25*x + 68*(10-x) = 37.9*10
25x + 680 - 68x = 379
680 - 43x = 379
680 - 379 = 43x
301 = 43x
43x = 301
x = 301/43
x = 7
Recall that x, was for the 25% mixture, 7 tons.
a) For the 68% mixture, = 10 - x = 10 -7 = 3 tons.
b) For the 25% mixture = x = 7 tons.
