This is quite simple. We will first add the amount of miles walked together.
3.25+5.5=8.75
Then we will divide 175 by the number of miles walked which in this case is 8.75.
Then we get 20 which is the amount of money that his parents donated for every mile that he walked.
Answer:
<u>Christine needs to drive 250 miles for the two plans to cost the same</u>
Step-by-step explanation:
For answering the question correctly and helping Christine, we will use the following equation:
x = number of miles driven
Cost of the first plan = 0.60x
Cost of the second plan = 50 + 0.40x
How many miles would Christine need to drive for the two plans to cost the same?
Cost of the first plan = Cost of the second plan
0.60x = 50 + 0.40x
0.60x - 0.40x = 50 (Subtracting 0.40x at both sides)
0.20x = 50
x = 50/0.2
x = 250 miles driven
<u>Christine needs to drive 250 miles for the two plans to cost the same.</u>
1 meter = 100 cm
while 5 meters = 500 cm
The random selection of a blue marble is an illustration of probability
You should expected to pull a blue marble 10 times
<h3>How to determine the expected blue marble?</h3>
The given parameters are:
Blue = 16
Red = 12
Green = 12
The total number of marbles is:
Total = 16 + 12 + 12
So we have:
Total = 40
The probability of selecting a blue marble is:
When 25 marbles are selected, the expected number of blue is:
So, we have:
Hence, the expected number of blue marbles is 10
