Please help me with this question

Mathematics
1 answer:
Maurinko [17]3 years ago

Answer:

  20

Step-by-step explanation:

The average term in the series is the average of the first and last terms:

  average term = (25 +101)/2 = 126/2 = 63

The sum of the series is the product of the average term and the number of terms:

  Sn = n(average term)

  1260 = 63n

  1260/63 = n = 20

The number of terms in the series is 20.

Lindsay and menonhave 1,240 stickers.menon has 4 times as many stickers as Lindsay.menon decides to have 6 stickers on each page
Lemur [1.5K]

a) Menon has 992 stickers. We can find this by writing an algebraic expression for the number of stickers, with x being the number that Lindsay has. This gives us:

x + 4x = 1240

5x = 1240

x = 248

Now we multiply 248 by 4 to get 992.

b) There are 2 stickers left over. First we have to divide 992 by 6, which gives us 165 as a whole number, but then a remainder of 2. That means that there are two stickers left.

c) Menon needs 4 more stickers, as 6 - 2 = 4, and there are 6 stickers per page.

I hope this helps! Let me know if you have any questions :)

wolverine [178]

Answer:

150%

Step-by-step explanation:

this is because you can make a part to whole ratio where you have x/100 (which would symbolize the percent) and 160/40 (which would symbolize the part) then, multiply 160 by 100 to get 16000 and then divide by 40 to fulfill the x. Hope this helps!
