The number of students in a newly opened school is 210. It is estimated that the number of students doubles each year. What is the estimated number of students in 5 years?

The answer is 6720

Step-by-step explanation:

(210 x 2) x 2) x 2) x 2) x 2) = 6720

Step by step its:

210 x 2 = 420

420 x 2 = 840

840 x 2 = 1680

1680 x 2 = 3360

3360 x 2 = 6720

1050 Students

Step-by-step explanation:

You can do 210 x 2 which gets you 420, and is 2 of the 5 years in total.

Next you can do 420 x 2, which is 840, and gets you 4 of the 5 years in total ( including the first steps years).

Then you can do 210 x 2, which we know is 420, and add it to 210 which we know is 1 year, and it gives you 1050, the total.

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm
