Answer: pool B has a greater circumference.
Step-by-step explanation:
The formula for determining the circumference if a circle is expressed as
Circumference = 2πr
Where
r represents the radius of the circle.
π is a constant whose value is 3.14
Pool A has a radius of 48 feet.
1 foot ≈ 0.305 meters
48 feet = 48 × 0.305 = 14.64 meters
The circumference of pool A is
2 × 3.14 × 14.64 = 91.94 meters
Pool B has a diameter of 29.46 meters. Radius = diameter/2
Radius of pool B = 29.46/2 = 14.73 meters
The circumference of pool B is
2 × 3.14 × 14.73 = 92.5 meters
Therefore, pool B has a greater circumference.
Answer:
The lines representing these equations intercept at the point (-4,2) on the plane.
Step-by-step explanation:
When we want to find were both lines intercept, we are trying to find a pair of values (x,y) that belongs to both equations, which means that it satisfies both equations at the same time.
Therefore, we can use the second equation that gives us the value of y in terms of x, to substitute for y in the first equation. Then we end up with an equation with a unique unknown, for which we can solve:

Next we use this value we obtained for x (-4) in the same equation we use for substitution in order to find which y value corresponds to this:

Then we have the pair (x,y) that satisfies both equations (-4,2), which is therefore the point on the plane where both lines intercept.
Multiply all terms by 12/1 to get rid of fractions.
8x+2= -9x+12
Add 9x to both sides
17x+2=12
Subtract 2 from both sides
17x=10
Divide both sides by 17
x=10/17
Final answer: x=10/17
An example of a unit rate would be driving a car at 50 miles per hour. 50 miles per every 1 hour is a unit rate.
Answer:
528 birds
Step-by-step explanation:
100%-15%= 85% = .85
1400 (.85)^6
= 528
