Answer:
The missing value in the ordered pair is 66
Step-by-step explanation:
Given that:
(12,10) and (-2,r)
Slope = m = -4
We have to find the value of r so that the line has a slope of -4.
Slope is the steepness of line which is denoted by m.
Here,

Putting the values in slope of line formula,

Multiplying both sides by -14

The value of r is 66
Hence,
The missing value in the ordered pair is 66
A + B + C = 180
x + 2x + 2 + 3x + 4 = 180
6x + 6 = 180
6x = 174
x = 29
Answer:
cosine rule - cos = 
Step-by-step explanation:
Here the ladder is acting as hypotenuse and base as adjacent.
Formula: cosθ = 
Convert liters to milliliters so that you have one unit for all of the amounts in the question.
1 liter is equal to 1000 milliliters, so multiply the 1.5 liters you have by 1000:

Since you drank 295 milliliters, and your friend drank 135 milliliters, you will subtract those values from the amount in the bottle:

There is
1070 milliliters of water left in the bottle. If you want to find the amount remaining in the bottle in liters, divide the amount remaining by 1000 to convert milliliters to liters:

Converted back into liters, there is
1.07 liters of water left in the bottle.
.06 of 1,000 =60 added
.02 of 1,000= 20 lost
Answer is 40 added, letter b
