Answer:
Step-by-step explanation:
Given the dimension of the homeowner's backyard to be width 18 yards long and length 16 yards long, the area of the rectangular backyard id expreesed as;
Area of rectangle = Length * Width
Area of the rectangular backyard = 18yards * 16yards
Area of the rectangular backyard = 288yards²
If they plan to put in a square pool with side length 5 yards long in the backyard, the area of the pool = 5yd*5yd = 25yd²
The remaining area that will contain the tiles = Area of the rectangular backyard - area of the pool
The remaining area that will contain the tiles = 288yd² - 25yd² = 263yd²
<em>Note that we cannot determine the amount of tiles they need to buy since we are not given the dimension of each tile to use</em>. The area needed for the tiles for the rest of the backyard is therefore 263yd².
Amount of tiles needed to buy can be expressed as 263/dimension of a tile.
2 yellow marbles, 7 red marbles, 1 green marble.....total of 10 marbles
probability of first picking a yellow marble : 2/10 reduces to 1/5
replacing the marble
probability of picking another yellow marble : 2/10 reduces to 1/5
probability of both is : 1/5 * 1/5 = 1/25 <==

2
Step-by-step explanation:
it's can be written as ^3√8 and taking it out is = 2
V + f - e = 2
e = v + f - 2
Answer:
AP = RA = 1.5 cm
PB = BQ = 8.5 cm
QC = CR = 3.5 cm
Step-by-step explanation:
The distance from the vertex to the two nearest tangent points is the same. If we say the distance AP = RA = x, then PB = BQ = 10-x, and QC = CR = 5 -x.
Since we know
BQ +QC = 12
We can substitute the above expressions involving x to find what x is.
(10 -x) +(5 -x) = 12
15 -2x = 12
x = (15 -12)/2 = 1.5
This tells us ...
AP = RA = 1.5 cm
PB = BQ = 8.5 cm
QC = CR = 3.5 cm
