Danny is taking a road trip. after 36 miles, he reaches a stretch of highway with a speed limit of 60 miles/hour. danny is trying to figure out the minimum number of hours he’ll need to drive to reach over 300 total miles for the trip, assuming he stays under or at the speed limit. he creates the inequality 60t + 36 ≥ 300, where t is the time elapsed, in hours. what statement is the most accurate? a. danny needs at least 7 hours to drive 300 miles. b. danny may drive 300 miles in 5 hours. c. at 4 hours, danny will have just driven 300 miles. d. it isn’t possible to drive 300 miles before the day is over.

step-by-step explanation:

what grade level is this? need to know so i can look in my old textbooks!

step-by-step explanation:

a cube has 6 sides

the probability of getting 5 on the first cube is 1/6 since only one side of the cube has 5 on it.

there are 3 sides of the cube with even number on it [2,4,6]

therefore the probability of getting even number is 3/6

for both events to happen together, the probability would be

1/6 x 3/6 = 12/36

which simplifies to 1/12

let x and 400 - x be the two numbers.  

==> 0.80x + 0.85(400 - x) = 400 - 68 from the statement of the problem.  

< ==> 0.80x + 0.85(400 - x) = 400 - 68  

==> 340 - 0.05x = 332  

< ==> -0.05x = -8 ==> x = 160, the first number ==> 400 - x = 240, the second number.
