Answer:

30 cents per week

Step-by-step explanation:

The average is the sum of the numbers divided by how many there are.

60 + 10 + 20 = 90

90/3 = 30

At 11:00 a.M., there are 400 members and 150 non-members visiting a museum. After 11:00 a.M., 10 members leave every five minute
alexdok [17]

Answer:

16:27

Step-by-step explanation:

GIVEN: At 11:00\text{ A.M.}, there are 400 members and 150 non-members visiting a museum. After 11:00\text{ A.M.},  10 members leave every five minutes and 5 non-members arrive every five minutes.

TO FIND: ratio of members to non-members at 1:00\text{ P.M.}

SOLUTION:

Total number of members in museum at 11:00\text{ A.M.} =400

as after every 5 minutes 10 members leave

total number of  5 minutes interval in 2 hour =\frac{60}{5}=12

total members at  1:00\text{ P.M.}  =400-10\times24

                                                =160

Total number of non-members in museum at  11:00\text{ A.M.} =150

as after every 5 minutes 5 non-members arrive

total number of  5 minutes interval in 2 hour =\frac{60}{5}=12

total non-members at  1:00\text{ P.M.}  =150+5\times24

                                                        =270

ratio of members to non-members at   1:00\text{ P.M.}  =\frac{\text{number of members}}{\text{number of non-members}}

                                                                                  =\frac{160}{270}

                                                                                  =\frac{16}{27}

Hence the ratio of members to non-members at 1:00\text{ P.M.} is \frac{16}{27}

Gwen buys 3 identical pairs of shoes at Store a. She pays $110.25 after the discount. what is the original price of each pair?
emmasim [6.3K]
In perspective this looks tricky but really its no ;) just follow it slowly.
110.25  is your total cost 
3 is how many you bought.
So doing division 3/110.25= 36.75
CHECK: 36.75 + 36.75 + 36.75 = 110.25.
Hope this helps.

Angle A and B are supplementary. Angle a has a measure of 80. What is the measure of angle B? The measure of angle B is
ololo11 [35]
Well when two angles are supplementary they equal 180.
So if angle A is 80 degrees then that would mean that angle B equals 100 degrees. 


Hope This Helped :)

Is it possible to form a square whose area is 18 by connecting four lattice points? Explain.
Cloud [144]
Note the squares... 13 is possible because it is a sum of two squares (integers) 9 + 4 .. use (0,3) & (2,0) ... get the square roots and place on different coordinate axes... for a simpler value. but there is none for 15... there is one for 18 ... 18 = 3^2 + 3^2 ... try (0,3) ,(3,0) , (3,6), (6,3).
