Answer:
117649
Step-by-step explanation:
First lets evaluate the parts:
7^8 = 5764801
7^7 = 823543
7^6 = 117649
adding and subtracting these 3 values as stated in the expression results in 5058907 which when divided by 43 is 117649.
While there is probably a faster way to do this, this does work.
V=number of videos, x=total amount
10v*3=x
Since each video is $10, you would have to multiply that by the number of videos. Once you find that you would multiply that number by three, since you will be keeping the videos for 3 days. With that you will find, x, the total amount.
Answer: D.
Step-by-step explanation:
Given : The charge of painting = $2 per square yard
Let x be the total cost of painting the triangular wall .
The base of the triangular wall = 4 yards
The height of the triangular wall = 6 yards
We know that the area of the triangle =
Thus, the area of the triangular wall =
Now, the total cost of painting the triangular wall =
Hence, the total cost of painting the triangular wall
Ignore the decimal places and do 789x38 and you get 29982. Now all you have to do is put the decimal places back. Since 789 was 7.89 it had 2 decimal places and 38 had 1 you have to move 29982 three decimal places to the left making your final answer 29.982.
Answer:
See below:
Step-by-step explanation:
The term is used to show the function of x and is essentially the same as y in some cases. One being right now.
So we know the function and we know that we want to solve for .
So what we can do, is input 12 as n in the original function.
Therefore, we get
Using algebra, we can solve it and we get 11!
