T is equal in both situations ... d = r X t so d/r = t
c is rate of waters current
14(12 - c) = 7(12 + c)
2(12 - c) = 12 + c
24 - 2c = 12 + c
12 = 3c
4 = c The rate of the waters current is 4 miles per hour.
I think the answer is y=1/4x+2 :)
To find the answer you have to first find how many degrees are there in between each number in the clock. the clock is 360°degrees and there are 12 numbers marked in a clock., so you have to divide 360 by 12 to get the number of degrees in between each number,
360°÷12=30° so there are 30°degrees between each number.
if a clock hand moves from 12 to 5, it pass 5 numbers, so to get your final answer you have to multiply 30° by 5=150°.
so your answer is 150°degrees.
hope you can understand what i said. :)
Answer:
-30 - 4n
Step-by-step explanation:
-34, -38, -42, -46, -50 ...
the sequence first term is -34
a= -34
Common difference (d) = T2 - T1 = T3 - T2
d = -38- -34 = -42 - - 38 = -38+34
d = -4
Formula for nth term
Tn = a + (n-1)d
Tn = -34 + (n -1)-4
Tn = -34 -4n + 4
Tn = -30 - 4n
= -30 - 4n

A = 180(n - 2)
a = 180n - 180*2
a = 180n - 360
180n - 360 = a
180n = a + 360
n = (a + 360) / 180
Numerator for fraction above = ( a + 360), denominator = 180
