Answer:
180 = 150m + c
177.25 mm
Step-by-step explanation:
L = mT + c
180 = m(150) + c
180 = 150m + c
c = 180 - 150m
181.5 = 210m + c
181.5 = 210m + 180 - 150m
1.5 = 60m
m = 0.025
c = 180 - 150(0.025)
c = 180 - 3.75
c = 176.25
L = 0.025T + 176.25
T = 40
L = 0.025(40) +176.25
L = 177.25 mn
Answer:
180 = m*150 +c
L= 177.25
Step-by-step explanation:
L = mT + c
We know T = 150 and L = 180
180 = m*150 +c
Then we are given T = 210 and L =181.5
181.5 = m210 + c
We have two equations and two unknowns
181.5 = m210 + c
180 = m*150 +c
Subtract the second equation from the first
181.5 = m210 + c
-180 = -m*150 -c
-----------------------------
1.5 = 60m
Divide each side by 60
1.5/60 =m
.025 = m
Now we need to find c
180 = .025*150 +c
180 =3.75+c
Subtract 3.75 from each side
180-3.75 =c
176.25
The equation is then
L = .025T + 176.25
Let T= 40
L = .025(40) +176.25
L = 1+176.25
L= 177.25

Answer: 1/6
Reason:
There's 1 side labeled "4" out of 6 sides total. So that's where the 1/6 comes from.
The "given that you already rolled a four on the first die" is unneeded info in my opinion, because each die is separate or independent from one another.
