Alyaa gets 15 signatures each day for 12 day. One the thirteenth day Alyaa get 55 signatures. Alyaa is trying to get 500 signatu
amid [387]
Okay dso if she got 15 points for 12 days then you would multiply them (or just add 15+15+15+15 and so on but multiplying is easier) then you are going to add 55 because of the thirteenth day. 
15(12)=180
180+55=235 is how many you have.
now you are going to subtract 500 from that number to see how many more you need. :)

Given: Q = 7m + 3n, R = 11 - 2m, S = n + 5, and T = -m - 3n + 8.
Oxana [17]

Answer:

6m + n + 2

Step-by-step explanation:

[7m + 3n - 11 - 2m] + [n + 5 - -m - 3n + 8]

[5m + 3n - 11] + [n + 5 + m - 3n + 8]

5m + 3n - 11 + (-2n + 13 + m)

5m + 3n - 11 - 2n + 13 + m

6m + n + 2

We are planning a reception for our daughter. The hall that we are renting charges $55 clean up fee. In addition to the cleanup
elena55 [62]

Answer:

89 is  the maximum number of guests that can be invited within budget  .

Step-by-step explanation:

The cleaning charges = $55

Total budget available = $3350

Cost per guest = $37

Now, actual budget available for guest = Total budget -  Cleaning Fee

= $3350  - $ 55   = $3,295

Now, cost per head =$ 37

So, number of guests (n) possible in the budget

⇒ n = (Total guest Budget)/ Cost per head

= $3,295 / $37  = $89.05

or,  n = $89.05

So, 89 is  the maximum number of guests that can be invited within budget  .

A 50-gallon rain barrel is filled to capacity. It drains at a rate of 10 gallons per minute. Write an equation to show how much
makvit [3.9K]

Answer:

The quantity of water drain after x min is 50 (0.9)^{x}  

Step-by-step explanation:

Given as :

Total capacity of rain barrel = 50 gallon

The rate of drain = 10 gallon per minutes

Let The quantity of water drain after x min = y

Now, according to question

The quantity of water drain after x min = Initial quantity of water ×  (1-\dfrac{\textrm rate}{100})^{\textrm time}

I.e The quantity of water drain after x min = 50 gallon ×  (1-\dfrac{\textrm 10}{100})^{\textrm x}

or,  The quantity of water drain after x min = 50 gallon × (0.9)^{x}

Hence the quantity of water drain after x min is 50 (0.9)^{x}  Answer
