ANSWER

EXPLANATION
The given line passes through the origin, hence it has equation of the form,

Therefore y varies directly as x.
The line passes through the point (3,1)
This implies that,


Hence the constant of variation is

The equation is

Answer:
A) total distance covered = 60miles
B) total time taken = 4hrs 30 mins
Step-by-step explanation:
Detailed explanation and calculation is shown in the image below
If a vertical line crosses the relation on the graph only once in all locations, the relation is <span>a </span>function. If<span> a vertical line crosses the relation more than once, the relation is </span>not a function<span>. So number 18 is not a function but number 19 is a function.

Answer:
1. 140
2. 140
3. 40
4. 40
Step-by-step explanation:
The lines are parallel so angels 1,4,5,8 are the same.
Same with angels 2,3,6,7.
To find angels 7 and 2 subtract 140 with 180 since the horizontal line equals 180 which gives you 40
The square footage of the path is 47.1 ft²
The area of a circle is:
A = πr²
Where r is the radius of the circle.
Let us assume that the pool is a circle.
Given that the pool has a radius (r₁) of 7 feet and a path 1 foot wide would go round the pool.
Radius of pool and cement path (r₂) = 7 ft + 1 ft = 8 ft.
The square footage of the path = πr₂² - πr₁² = π*8² - π * 7² = 47.1 ft²
Hence The square footage of the path is 47.1 ft²
