Answer:
Jamal needs to save $254.17 each month to cover his expenses.
Step-by-step explanation:
We know that there are 12 months in a year, and Jamal already has $1,000 towards college. Jamal still needs to save $3,050 more dollars because: 4,050 - 1,000 = 3,050. Next, we take how much he has yet to pay ($3,050) divided by how many months in 1 year (12), and that gives us 254.17 per month.
Answer:
x(6x-5)
Step-by-step explanation:
take something from both equally
Answer:
a taco is 1.25 and a drink is 0.95
Step-by-step explanation:
tacos = t
drinks = d
5t + 3d = 9.10
3t + d = 4.70
this is a simultaneous equation so times the first one by one and the second by 3 and then take them away from each other and solving to get
t = 1.25 and d=0.95
one drink is $0.95
one taco is $1.25
Hope this helps!!
Answer:
5 months
Step-by-step explanation:
Equation A: 15+30x
Equation B: 35x
In 5 months Gym a will cost 15+30(5) or $175 and Gym B will also cost $175.
Basically all you have to do is apply reasonable numbers until you find out where the costs will meet up.
Answer:
0.0492
Step-by-step explanation:
Based on the tree diagram we need to tell the the probability that the test for lice returns a false positive. False positive means that the student has no lice but still the test shows a positive result.
So for this we have to first look for the branch, from the starting node, which shows that student has no lice. From the starting point, the upper branch represents the students that have lice and lower branch represents the students who have no lice. So, we will consider the lower branch with probability mentioned as 0.82
Now, the lower branch is divided into two branches further. We have to look for the branch which shows positive test result. This would be the upper branch with probability mentioned as 0.06.
The overall probability of this event is mentioned at the end of the branch which is 0.0492
This is the probability of the combined event: Student has no lice but tests shows positive result which is the False positive.
Thus, the probability that the test for lice returns a false positive is 0.0492
