The error is when you multiply -7 by -1 it is 7 not -7 so,
-14+7-21
-7-21
-28
Also where did r come from you asking 2 different questions
Answer:
Jeff’s speed is 7 mph
Jon’s speed is 6 mph
Step-by-step explanation:
Since the time spent by each is same, let us call the number of hours x
Mathematically;
Time = distance/speed
Let us call Jeff’s speed y
x = 14/y ••••••(i)
For Jon
he hiked 1 mph slower, so his speed will be (y-1) mph
x = 12/(y-1)
Since x is equal in both cases
14/y = 12/y-1
14(y-1) = 12y
14y -14 = 12y
14y-12y = 14
2y = 14
y = 14/2
y = 7 mph
Jon is 1 mph slower which is 7-1 = 6 mph
8 .. 4 x 4 x 1/2 = 8 ... sorry if I’m wrong
To find the percent, we first find the decimal.
To do that we divide 5 / 6, which gives us approximately 0.83333, now we multiply it by 100 since percentages are parts of 100.
0.83333 * 100 = 83.33%
Answer:
The answer is 305 degrees
Step-by-step explanation:
Firstly, we identify the quadrant
South-East represents the fourth quadrant
The angle range here is 270-360 degrees
So we simply add 35 degrees to 270
Thus, we have 270 + 35 = 305 degrees
