Answer:
Part a)
Part b)
Step-by-step explanation:
Part a) Create a linear equation
Let
t ----> the time in minutes
y ---> the temperature in °F
we know that
The linear equation in slope intercept form is equal to
where
m is the slope or unit rate of the linear equation
b is the y-intercept or initial value of the linear equation
In this problem we have
The slope m is equal to
The y-intercept is
substitute
Part b) How many minutes until the water boils at 212° F?
For y=212° F
substitute in the linear equation and solve for t
Answer:
2
Step-by-step explanation:
For Urn 1,
total number of balls = 8 (green balls) + 12 (red balls) = 20 balls
The probability of picking a red ball from Urn 1 is equal to 12/20 or 6/10 or 3/5.
For Urn 2,
total number of balls = 5 (green balls) + 8 (red balls) = 13 balls
The probability of picking a red ball is 8/13.
The probability of picking both red balls from the two urns is the product of the two probabilities which gives us the answer which is equal to 24/65. The answer is letter B.
Answer:
ED = 31
DT = 20
Step-by-step explanation:
m< ESD = 90-52=38°
the distance ED = 40×tan 38° = 31.25 = 31
ET = 40 x tan (90-38) = 40×tan 52°
= 51.19= 51
the distance DT = 51-31 = 20
The answer is C. Isolating a variable in one of the equations.
