There are two ways you can do this. You can use the longer way:
15+16+17+18+19+20+21+22+23+24 = 195 (starting from the top row, which has 15 logs, up until the bottom row, which has 24 logs, on condition that each second row has one log more than the previous one)
You can also use the formula (where n is the number of rows)
x= (n(first term+last term))/2
x= (10(15+24))/2
x= (10*39)/2
x=390/2
x=195
Either way, there are 195 logs in the stack.
Answer:
A statement that shows current balance of an account and all transactions that occurred on that account since the last statement.
Transactions such as deposits, withdrawals, checks written, debt card uses...
There are other examples of bank statements for things like home loans, business loans, and investments.
Well, if the notebooks cost x, then you know that
3x + 45.87 = 60.54
right? so, solve for x. 60.54 - 45.87 = 14.67
Divide the difference by 3.
Answer:
The center of circle D is (-0.5,3)
Step-by-step explanation:
Given the end points of diameter: (-5,8) and (4,-2)
To find: Center of the circle.
Center is in the middle of the diameter. Therefore we have to find the midpoint of the diameter.(refer figure)
Midpoint of a line with end points (x1, y1) and (x2, y2) is given by
( 
, 
)
( 
, 
)
(-0.5,3)
Hence the center of circle D is ( -0.5,3)
