Write the ratio in simplest form for area of pool/ area of yard
1 answer:
Answer:
Option (C)
Step-by-step explanation:
From the map attached,
Area of the rectangular yard = length × width
Length of the yard = 10 units
Width of the yard = 8 units
Area = 10 × 8
= 80 square yards
Since, pool is a composite figure of two rectangles,
Therefore, area of the pool = Area of large segment + Area of the small pool
= (5 × 6) + (3 × 3)
= 30 + 9
= 39 square units
Ratio of Area of the pool and area of yard =
Therefore, Option (C) will be the answer.

Set up a proportion based on the triangle side lengths. I chose to put the smaller ones over the bigger ones:
Then cross multiply to get 1344-42x = 6x
Add 42x to both sides to isolate the x changing the equation to 13444 = 48x
Divide both sides by 48 to get x = 28

Answer:
The x-intercept will tell you how many seconds have passed before Dante lost sight of the rock.
Step-by-step explanation:
The problem specifies that the function d(s) will model the depth in feet of a rock that Dante dropped into a lake s seconds after he lost sight of the rock.
In this case we are using an s instead of the x, so the x-intercept will represent a given time. We can find the x-intercept by setting the function equal to zero, like this:
-5s-15=0
when solving for s we get:
s=-3
This means that Dante dropped the ball into a lake 3 seconds before he lost sight of the rock. This is what the negative stands for, some time in the past.
So the x-intercept tells us the time it took for Dante to lost sight of the rock.
