Give the equation of the circle centered at the origin and<br> passing through the point (4,0)

zimovet [89]

Answer:

x² + y² = 4²

Step-by-step explanation:

The standard equation of a circle centered at the origin and with radius r is

x² + y² = r²

Note that the point (4, 0) is 4 units horizontally and to the right of the center (0, 0). Thus, we know immediately that the radius is 4.

Thus the equation of this circle is x² + y² = 4²

Samaria has 6 more than three times as many pieces of candy as sydney. samaria has 36 pieces of candy. how many does sydney have

lesya [120]

For this case we have:

x: Number of candies that Sydney has

The equation to find the amount of Sydney sweets is given by:

$3x + 6 = 36$

We want to clear x:

$3x = 36-63x = 30$

$x = \frac{30}{3}$

$x = 10$

So, Sydney has 10 candies

Answer:

Sydney has 10 candies

Answer:

$\text{Average rate}=\frac{\text{40 laps}}{\text{ hour}}$

Step-by-step explanation:

Please consider the complete question.

Sebastian swan laps every day in the community swimming pool. He swam 45 minutes each day, 5 days each week, for 12 weeks. In that time, he swam 1800 laps. What was his average rate in laps per hour?

Let us convert time taken into hours as:

$\text{Days}=5\times 12=60$

$\text{Minutes}=60\times 45$

1 hour = 60 minutes. To convert minutes into hours, we will divide total minutes by 60.

$\text{Hours}=\frac{60\times 45}{60}=45$

Now, we will divide 1800 by 45 to find average rate in laps per hour as:

$\text{Average rate}=\frac{\text{1800 laps}}{\text{45 hours}}$

$\text{Average rate}=\frac{\text{40 laps}}{\text{ hour}}$

Therefore, Sebastian's average rate is 40 laps per hour.
