Answer:
( 300; 353) is on the line y=1.2x−7
Step-by-step explanation:
y=1.2x−7
Substitute the point into the equation and see if it is true
353=1.2(300)−7
353 =360-7
353 = 353
This point is on the line
Step-by-step explanation:
8-4=5x-2x =4=3x=4/3 =3x/3 x=1.5
Using the law of cosin
cos(angle) = adjacent leg / hypotenuse
We fill in what we know and solve for x:
cos(30) = x / 10
x = cos(30) * 10
x = 5 SQRT(3)
2 1/3 does not involve radicals. Did you perhaps mean 2^(1/3)? If so,
2^(1/3) = ∛2
Answer:
70%
Step-by-step explanation:
Well, you have 3 hours to work with, which is 180 minutes. You subtract 30 minutes from warm up, then subtract another 24 minutes for group work time, and you're left with 126 minutes. Now, to figure out the percent, you take 126 divided by the total time (3 hours or 180 minutes)
126 / 180 is 0.70, which as a percent is 70%.
