Answer: 145 cans
Step-by-step explanation:
arithmetic sequence
aₙ = a₁ + (n-1).r
aₙ → last term
a₁ → 1st term
n → quantity of terms
r → common difference
a₁ = 1 (one can at the top)
aₙ₋₁ = 25
aₙ = 28
To find out How many cans are in the entire display, we need the SUM of the arithmetic sequence: S = (a₁+aₙ)n/2
∴
S = (1+28).n/2
n = ?
aₙ = a₁ + (n - 1).r
r = 28 - 25 = 3
28 = 1 + (n - 1).3
27 = (n - 1).3
27/3 = (n - 1)
9 = n - 1
n = 9 + 1 = 10
S = (1+28).n/2
S = (1+28).10/2 = 29.10/2 = 29.5 = 145
Answer:
Red color= 28 balloon
Blue color= 14 balloon
White color= 7 balloon
Step-by-step explanation:
Given: There are 49 balloons
As given, there are 2 red balloon equal to the number of blue balloon
∴ 
Again given, there are 1/2 white balloon equal to the number of blue balloon.
∴ 
As above equation, we can understand that:
multiplying both side by 2
⇒ 
which mean, if we have 2 blue balloon then we will have 4 red and 1 white balloon.
∴ Total combination of all color of balloon= 
Now, checking how many number of times combination can we have in 49 balloon.
Next, finding number of balloon in each color.
Red color= 
Blues color= 
White color= 
Well, if you use the net diagram, the one below the pyramid, this is how to do it:
First, find the area of the square, or the base. That would be 10 * 10 = 100ft.
Then, you find the areas of all of the triangles, which is this formula: A= BH / 2.
So you would do 10 * 12 / 2 for each triangle, or you can just make them squares, since there are four triangles, and it would turn into 10 * 12 * 2 for all of them. That was just an easier way to figure it out, but you could have done each triangle and then added them all up.
Finally, add what you get for the triangles, 240ft, with the area of the square, 100ft. You get 340ft².
Your answer will be 340ft².
Hope this helped!
