Norma-Jean [14]

Answer:

54minutes

Step-by-step explanation:

Let the time taken to clean up be t

Let the number of people cleaning be n

If the time it takes to clean up after an anniversary party varies inversely as the number of people cleaning then;

t = k/n

k is the constant of proportionality

If 3 people work together to clean, and took them 90 minutes, this means

at t = 90, n=3

Substitute

90 = k/3

k = 3×90

k = 270

To et the time it will take 5people to clean, the will say;

t =k/n

t =270/5

t = 54 minutes

Hence it will take 5 people 54minues to clean

Can someone please help me thank you
Step2247 [10]
Pick one coordinate point on figure 1 (-4,5)

First rotate 90 degree clockwise rule (x,y) -->(y , -x)
So (-4,5) rotate 90 degree clockwise will become (5, 4)

Then reflection over x a-xis, rule (x,y) -->(x,-y)

So (5, 4) reflection over x a-xis will be (5, -4)

Answer: first option
90 clockwise rotation around the origin, then a reflection across x - axis.

Hope it helps

Nina [5.8K]

Answer:

In year 2039 both the events will happen again.                    

Step-by-step explanation:

We are given the following in the question:

Family reunion:

Every 7 year

Update the family tree:

Every 6 years

1997 was the year when they had a family reunion as well as they updated their family tree.

We have to find the year in which both the events will occur together.

We find the lowest common multiple of 7 and 6.

L.C.M(7,6) = 7\times 6 = 42

Thus, after 42 years both the event will happen again.

Year:

1997 + 42 = 2039

Thus, in year 2039 both the events will happen again.
