Answer: Perpendicular
y = 5 is a horizontal line through 5 on the y axis
x = -1 is a vertical line through -1 on the x axis
Answer:
18 minutes
Step-by-step explanation:
Given that:
The arrival time = 3 customers / hour
The avg. service rate (s) = 12 minutes per customer
To hour, we have:
s = 5 customers/ hour
Thus, the required average time for a customer needs to wait in line is:
To minutes;
= 18 minutes
Answer: <em>1.1 × 10⁸ cm³</em>
Explanation:
1) Since the ball is spherical, you use the volume formula for a sphere, which is:
Volume = [4/3] π r³
2) r is the radius, which is given and is equal to 3×100cm = 300cm
3) Pluging in the value of r, you get:
Volume = [4/3] π (300 cm)³ = 113,097,335.53 cm³
4) Since, r = 3×100 cm has two significant figures, the result must show only two significant figures.
So, using scientific notation, the right answer must be reported as:<em> 1.1 × 10⁸ cm³</em>
Answer:
Step-by-step explanation:
Because 
is being multiplied by S, we can divide from both sides of the equation. This will give us:
÷
But, that looks a bit hectic. Instead of dividing, you can multiply by the reciprocal (which is essentially how to divide fractions). So, instead of ÷, you get:
×
When multiplying fractions, remember you can just multiply straight across-- numerator x numerator, then denominator x denominator.
By doing that, you get the fraction
cannot be simplified any more, so S= is your answer :)

If she stopped at 8;05, and she started 20 minutes earlier, just imaging a clock at 8:05 and turn back time 20 minutes.
Five minutes would be 8:00, ten minutes is 7:55, fifteen minutes is 7:50, and twenty minutes is 7:45. This, she started at 7:45
