The answer I believe would be A
A River Oaks Pools is trying to calculate the perimeter of the pool so they will know how many bricks to buy for the deck of the pool. Each square on the grid represents a square that is 3ft x 3ft. What is the perimeter of the pool?
Solution:
On the first row and last row, there are 7 numbers of squares. And on the 2nd to 5th row, there are 11 number of squares.
In getting for the perimeter of the area, we'll have to divide the regions.
Dividing the regions, we'll get three figures/planes :
2 rectangles with Length = 3ft x 4 number of squares and Width = 3ft x 2 number of squares
Thus, for the 2 rectangles,
Perimeter = 2(2L+2W) (times two since there are 2 rectangles)
Perimeter = 2(2(12)+2(6))
Perimeter = 72 ft
Another figure was formed is a square with a 21ft x 21ft
Perimeter = 4(21ft)
Perimeter = 84 ft
Add the two equivalent perimeters:
Total Perimeter = 72+84
Total Perimeter = 156 ft
Answer:
A - Subtracting all costs from the total benefit.
Explanation:
Opportunity cost is the cost of doing something that might benefit you. For example, the Opportunity cost of playing Minecraft with your buddies is maybe completeing the remaining questions of your homework. This being true, makes the answer choice A the most logical one.
The answer is C. keep enough strength in the senate to protect southern interests
Back then, Slavery is almost a way of life of southerners.Back then, the productions amount in northern part of USA is way more than the south. And the Northerners did that without slavery
In 1808 , the congress abolished slave trading with Africa, making the economic difference between the south and north separated even further
In order to protect their own interest, they want slavery to extend to the north so they have enough strength in the senate to protect its legality
Answer:
Explanation:
The speed of the ball in meters per second is
Where t denotes the number of seconds since the ball has been thrown and 
is the initial speed of the ball. Then:
If the ball travels 25 meters during the first 2 seconds after it is thrown, what was the initial speed of the ball
Also, for constant acceleration motion, the average velocity is equal to the sum of final and initial velocities divided by 2 and to the distance divided by the time:
Where you know:
Substituting (the units are ommited in the equationn, but added at end of the answer):
Thus, you have a system of equations:
Substituting the second into the first:
