Answer:
58.75 degreeF
Step-by-step explanation:
The initial temperature of the Soda = 40degreeF
The temperature outside is steady at 99 degreeF
The temperature of the soda became 50 degreeF after 8 minutes
In 8 minutes, the Soda gained
(50 - 40)degreeF
= 10 degreeF
If the soda gains 10 degreeF in 8 minutes, in 1 minute, it will gain 10/8degreeF
Therefore in 7 minutes, the soda will gain (10/8)*7
= 70/8
= 8.75 degreeF
The expected temperature of soda after an additional 7 minutes = 50 + 8.75
= 58.75degreeF

Let's add all the values on one side and make it equal to the sum of all the other values on the other side
(- X) + (- X) + (- X) + (- X) + (- X) + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 = X + X + X + (- 1) + (- 1) + (- 1) + (- 1) + (- 1) + (- 1) + (- 1) + (- 1)
- 5X + 12 = 3X - 8
- 5X - 3X = - 8 - 12
- 8X = - 20 x(- 1)
8X = 20
X = 20/8
<h2>X = 5/2</h2>
<em>or X = 2.5</em>
Answer:
Step-by-step explanation:
To define the perpendicular line we need to first know the slope of the reference line graphed.
m=(y2-y1)/(x2-x1) we have points (0,5) and (2,1)
m=(1-5)/(2-0)
m=-4/2
m=-2
For lines to be perpendicular their slopes must satisfy
m1m2=-1, we have a line with a slope of -2 so
-2m=-1
m=1/2, so our perpendicular line is so far
y=x/2+b, it must have point (3,2) so we can solve for b
2=3/2+b
b=1/2, so the swimmer will travel along the line
y=x/2+1/2
