Answer:
34p-16
Step-by-step explanation:
Perimeter of parallelogram
= 2(9p-10)+2(8p+2)
= 18p-20+16p+4
= 34p-16
So, how much acid is there in 6 gallons? well is 20% acid or (20/100), so the amount of acid in it just (20/100) * 6 or 1.2, the rest is say water.
now, if we want a 90% solution, and say we add "y" gallons, how much acid is in it? well (90/100) * y, or 0.9y.
now let's add "x" gallons of pure acid, now, pure acid is just pure acid, so is 100% acid, how much acid is there in it? (100/100) * x, or 1x or just x.
we know whatever "x" and "y" amounts are, they -> x + 6 = y
and we also know that x + 1.2 = 0.9y
Answer:
58+4=62 Sienna’s height is 62 inches
Explanation:
Sienna’s height is 62 inches because Georgia’s height is 58 inches and she is shorter by 4 inches which means you have to add 58+4 which would equal 62.
Step-by-step explanation:
We are given:
This can be rewritten as
Next, we can bring the x's and y's to their respective sides by dividing by coty and x and then multiplying the dx to the other side. We can then change into . This gives us the differential
Now we can integrate each side
To integrate tan(y), we need to manipulate it
Now we can use u-substitution where
This gives us
Now, lets integrate both sides
Next, we can substitute our u value back in
Now we can add to the other side and subtract c from each side. This gives us
Next, we can apply a property of logarithms to combine this sum of two logs into one log.
Lastly, we can add a base e to each side to remove the ln
And here is our answer.
Answer:
Bus B must be A) y = 40x
Step-by-step explanation:
We can tell this because it is growing at a slower rate than Bus A. As a result, we know the slope is less than 55. The only option that is less than 55 is A) 40x.
