Answer:
450 miles
Step-by-step explanation:
there is a 2 hr difference in betwen them. when you take 450 there is a 150 mile difference from 300 so when you divide 150 by 2 you get 75 so you do about 75 miles an hr so you can go 450 miles in 6 hr's.
Answer:
The stack is inches high.
Step-by-step explanation:
Given date:-
A stack of 7 crates means
1 stack=7 crates
Total number of crate=7
Height of 1 crate =
Height of 1 crate = inches
Height of 1 crate = inches
To find height of stack=?
Now,
Height of a stack = Height of 1 crate Total number of crates
Height of a stack =
Height of a stack =
Height of stack = inches
Therefore the stack is inches high.
Answer:
x = 25 degrees
Step-by-step explanation:
sin theta = -9/41, where theta is in Q IV; find the angle theta:
Here the opp side is -9, the hyp. is 41. The adj side is found by applying the Pyth. Thm.:
(-9)^2 + x^2 = 41^2
81 + x^2 = 1681. Then x^2 = 1600, and the adj. side (x) is +40. We know it's +40 because theta is in Q IV.
The angle theta is arcsin (-9/41). Using a calculator,
arcsin (-9/41) = -0.22 radians (which is correct because theta is in Q IV, just as -0.22 rad is in Q IV. You could express theta as a positive angle by subtracting 0.22 rad from 2pi rad: 1.78 rad. You could, of course, change these angles in radians into angles in degrees.
