Answer:
15x + 15° = 3x + 9° + 78° (exterior angle is equal to the sum of the opposite interior angles)
15x - 3x = 9° + 78° - 15 °
12x = 72°
12x÷12 = 72°÷12
x = 6
Input is time, this is your x-values
output is the total cost, this is your y-values.
in the question above "this mapping diagram shows...." so i'm not sure if there more to the question or what the question actually is, but if you have to create a mapping, you will create a list of x values for days and y values for corresponding total cost.
Day 1 cost $40 (1,40)
Day 2 cost $80 (2, 80) ($40 per day for 2 days = 40 (2) = $80
Day 3 cost $120 (3, 120) ($40 per day for 3 days = 40(3) = $120
hope this answers your question. :-)
Answer:
The answer is 165/6, or 27 and one half.
Step-by-step explanation:
12 liters for 4 days....12/4 = 3 liters per day
for 15 liters.....15/3 = 5 days....Lexi spent 5 days
Answer:
There are 67,600 possible combinations for this vault.
Step-by-step explanation:
First dial: 100 possible values
Second dial: 26 possible values
Third dial: 26 possible values.
How many possible combinations are there for this vault?
Multiplication of these values. So
100*26*26 = 67600
There are 67,600 possible combinations for this vault.
