Im not so sure about Q2 but 3 and 4 are correct for sure.
Box 1 : 3 pencils + 7 pens = total of 10
probability of picking a pen is 7/10
box 2 : 3 pencils + 3 crayons = total of 6
probability of picking a crayon is 3/6 which reduces to 1/2
probability of picking both is (7/10 * 1/2) = 7/20 <==
replace 15 for t in the equation
V915) = 20 + 7 cos(15) = 26.76148078 feet per second
26.76148078 x 15 = 401.4222118 feet
round off to 401.42 feet
No. Round 146 to 150 and add both 270 and 150. It's 420. So 400 would be more reasonable. 300 is not reasonable because it ain't close.

Step-by-step explanation:
First, we need to make the denominators the same.
Then, we subtract the numerator.
