Answer:
B. 18 bags
Step-by-step explanation:
First you need to determine the area of the vegetable garden. The vegetable garden is a rectangle with the following dimensions:
L = 24 ft
W = 9 ft
The Formula for the area of a rectangle is:
So let's solve it:
With that, we can figure out how many bags of fertilizer would be needed by dividing the area of the vegetable garden by how much one bag of fertilizer covers:
Answer:
8428
Step-by-step explanation:
According to the Question,
- Given, A theater has 56 rows of seats. If there are 13 seats in the first row, 18 in the 2nd row, 23 in the 3rd row.
We have a number sequence 13, 18, 23, ...
- We can say that this is an arithmetic sequence because of the common difference 'd', is equal to 5, and the first term 'a1' is equal to 13.
- The formula for the sum of an arithmetic sequence with n terms is given is
![S_n= \frac{n}{2} [2a_1+(n-1)d]S](https://tex.z-dn.net/?f=S_n%3D%20%5Cfrac%7Bn%7D%7B2%7D%20%5B2a_1%2B%28n-1%29d%5DS)
.
Substitute the given values into the equation to solve for the sum of the 56 rows of seats.
![S_56= \frac{56}{2}[2(13)+(56-1)(5)]\\S_{56}=28\left[26+275\right]\\S_{56}=28\left[301\right]\\S_{56}=8428](https://tex.z-dn.net/?f=S_56%3D%20%5Cfrac%7B56%7D%7B2%7D%5B2%2813%29%2B%2856-1%29%285%29%5D%5C%5CS_%7B56%7D%3D28%5Cleft%5B26%2B275%5Cright%5D%5C%5CS_%7B56%7D%3D28%5Cleft%5B301%5Cright%5D%5C%5CS_%7B56%7D%3D8428)
Therefore, there are 8428 seats in all.
Answer:
how you can divide them I believe
Step-by-step explanation:
you need to divided both of them to see a difference
Answer:
24 and 25
Step-by-step explanation:
From given, we have,
7 square = 49
Let the first positive number be = x
And the second consecutive positive number is = x+1
x + (x + 1) = 49
2x + 1 = 49
2x = 49 - 1
2x = 48
x = 24
the first number x = 24
the second consecutive number x+1 = 24 + 1 = 25
Thus, 7 square = 24 + 25 (the sum of two consecutive positive numbers.)
