5 men or 7 women or 9 girls can do a piece of work in 15 days. How many days will 1 men 1 women and 1 girl take to do the same
work?
In cummor camn food was available for 120 children at the rate of​

Step-by-step explanation:

5 men × 15 days = 75 man-days

Each man does 1/75 of the job per day

7 women × 15 days = 105 woman-days

Each woman does 1/105 of the job per day.

9 girls × 15 days = 135 girl-days

Each girl does 1/135 of the job per day.

Least common multiple of 75, 105, and 135 =

Working together, 1 man, 1 woman, and 1 girl do 1/75 + 1/105 + 1/135 = 143/4725 of the job per day, finishing in 4725/143 = 33.04 days

a. turk and mcalister

b. howard, mission, and market

c. yes. since streets end some do not cross yet are not parallel to others. example: mcalister and 5th

step-by-step explanation:

parallel lines are lines which do not intersect ever and look a lot like railroad tracks. turk, mcalister and golden gate are examples of these.

intersect are streets which cross each other and a car on one can reach the other. howard, mission, and market intersect with 6th.

skew lines are lines which neither intersect nor are parallel. these lines exist here because some streets end and never intersect another like mcalister and 5th.

the red lines denote the population of the bacteria after 35 hours. that would be 2,409.24. the y-intercept is the blue line which is 800 because that is the starting point. the equation used to make the graph is 800(1.032)^h, where h is the number of hours.
