Answer:
162 hours
Step-by-step explanation:
1 day= 24 hours
24 times 6= 144
144 + 18= 162
I believe it’s translation
Answer: 195
Step-by-step explanation:
Cost per student = $4
Total number who attended = n
The cost of the total of student who attended will be cost per student multiplied by the total number of students, that is
Total cos = 4n
Since, they are to pay $140 , for publicity, then the total cost becomes
T = 4n - 140
From the last statement
4n - 140 ≥ 640
4n ≥ 640 + 140
4n ≥780
n ≥ 780/4
n ≥ 195
That means at least 195 students must attend if the science club is to earn at least $ 640
It’s 500.07
all i did was solve x-7%=500 and got 500.07.
In Y=mx+b:
m=slope. That is found by using this formula y2-y1/x2-x1
b=y-intercept. That's found by finding slope, m, and substituting that into y=(m)x+b. Then you have to solve for b and that'll be your y-intercept.
