Answer:
45 tiles of dimension 8 ft by 8ft
Step-by-step explanation:
Since the tile is going to be a square, then both sides must be equal.
This means the lenght of the side of the square must divide without remainder, the lenght and the breadth of the outdoor play area. The highest common factor of 40 and 72 is 8. This means that the side of each square should be 8 ft.
This means that 5 of the 8 ft sided tile will cover the 40 ft width of the play area, and 9 of the 8 ft sided tile will cover the lenght of the area.
The total amount of tiles needed will then be 9 x 5 = 45
Answer:
D. 10 square units
Step-by-step explanation:
The area of a triangle is given by the formula ...
A = 1/2bh
__
This triangle has a base of 4 units and a height of 5 units. (These dimensions can be counted from the graph, or found by subtracting coordinate values.) Its area is ...
A = 1/2(4 units)(5 units) = 10 square units
_____
<em>Additional comment</em>
The first two coordinates lie on the line x=0. The length of that segment is the difference of the y-values: 4 -(-1) = 5.
The first and last coordinates lie on the line y=-1. The length of that segment is the difference of the x-values: 4 -0 = 4.
Answer: 27.3
Step-by-step explanation:
13 X 24 = 312
The square root of 312 is 17,6
So, the closet answer is 27.3
(Let me know if I'm wrong or right)
quadratic formula is used to find "zeros" or the x-intercepts, the x values where y = 0
take father's age as x
if it is doubled i.e 2x .we get the answer as 20 less than 100 which means 100-20=80
accordingly the equation will be 2x=80
x=40
given that ,
son is 1/4 th of his father
hence ,
son = 1/4×(x)
I.e, 1/4×40 =10
Hope it helps
