Answer:645 kilometers per hour
Solution.
Let v be the speed of the plane flying east!
Then, the speed of the plane flying west is v+75.
Since the planes are 5460 kilometers apart by 7 pm est,
(7-3)*(v+(v+75))=5460
2v+75=1365,
2v=1290,
v=645
answer: 645
Answer:
4^4
Step-by-step explanation:
Working from left to right
4^5 * 4^-7 ÷ 4^-2
We know that a^b * a^c = a^(b+c)
4^5 * 4^-7 = 4^(5-7) = 4^2
4^2 ÷ 4^-2
We know a^b / a^c = a^(b-c)
4^2 ÷ 4^-2 = 4^(2- -2) = 4^(2+2) = 4^4
Answer:
here, you are simply asked to find perimeter
so add all sides to find it. soln is below
a+5+2a-1+3a-7 = 6a-3= 3(2a-1) ans
Answer:
19/100
Step-by-step explanation:
19% is basically 19/100 which can't be simplified as 19 is prime
Answer: The distance is 17.
Step-by-step explanation:
Find their difference in the y values and the difference in the x values then find their absolute values.
2-17 = -15
-6 - 2 = -8
The absolute value of -15 is 15 and the absolute value of -8 is 8.
Now square them and add them up to find their square root.
15^2 + 8^2 = c^2
225 + 64 = c^2
289= c^2
c= 17
