We are given:
u+v
t=---------- and are to solve for u.
2
First, multiply both sides by 2; this will eliminate fractions:
2t = u + v. We want to solve this for u.
Subtracting v from both sides, we get 2t - v = u. Thus, u = 2t - v (answer)
Slope is change in y / change in x
Using the two points given:
Slope = (5-4) /(2-4) = 1/-2 = -1/2
slope = -1/2
C.
Although this is not the exact answer the circumference formula is 2(pi)r. Which is far more than the other two options.
Convert both fractions to get a LCD, then subtract
Answer is 3. 1/24
Answer:
1/2 minute
Step-by-step explanation:
We can use a ratio to solve
1/3 bottle 1 bottle
------------ = --------------
1/6 minute x minutes
Using cross products
1/3x = 1/6 *1
1/3 x = 1/6
Multiply each side by 3
3 * 1/3x = 3 * 1/6
x = 3/6
x = 1/2
1/2 minute
