Step-by-step explanation:
red: 2/5
White: 1/5
Black: 2/25
Green: 8/25
If she chose a marble fifty times how many greens would she get:
(8/25) x 50= 16
she would get 16 green marbles in 50 tries.
The slope of a line that is perpendicular to another line is the negative reciprocal of the other.
In this case, we know that the slope of the given equation is 2.
Since we're solving for a line perpendicular to it, we simply find the reciprocal of the 2 (It turns into 1/2) and make it negative.
y = -1/2x + b
Since the given states that the new y-intercept is 10, input it into 'b'.
y = -1/2x + 10
If you'd like me to explain anything I did here, just ask :)
-T.B.
Normallly people want miles per hour or miles/hour
so divvided 420 by 7 =420/7=60/1=60 miles per hour
So since the rate at which the small submarine is diving is 30 feet per minute, after 7 minutes the submarine would have been at a depth of 210 feet.
I Believe this has 1 solution therefore it is false :)
