Since the formula for circumference is pi*diameter, you multiply 3.14 by 622 mm to get 1953.08 mm as your circumference.

Answer: 1953.08 mm

Step-by-step explanation:

We know that circumference of a circle is given by ;-

$\text{Circumference}=2\pi r$ , where r is the radius of the circle.

Given: the diameter of the wheel = 622 mm

Then, the radius of the wheel = $\dfrac{622}{2}=311\ mm$

Now, the circumference of the wheel is given by ;-

$\text{Circumference}=2\pi (311)\\\\\Rightarrow\ \text{Circumference}=2(3.14)(311)\\\\\Rightarrow\ \text{Circumference}=1953.08\ mm$

Hence, the circumference of the wheel = 1953.08 mm.

Team tool bella canoed 15 3/4 miles in 5/4 hours. What was their average rate of speed in mph

luda_lava [24]

Average speed is 12.6 miles per hour

<em><u>Solution:</u></em>

Given that team tool bella canoed $15\frac{3}{4}$ miles in $\frac{5}{4}$ hours

To find: average rate of speed in miles per hour

From given information,

$distance = 15\frac{3}{4} \text{ miles } = \frac{15 \times 4+3}{4} = \frac{63}{4} \text{ miles}$

$time = \frac{5}{4} \text{ hours}$

To find the speed we use the below formula,

$speed = \frac{distance}{time}$

Substituting the given values we get,

$speed = \frac{\frac{63}{4}}{\frac{5}{4}}\\\\speed = \frac{63}{4} \times \frac{4}{5} = \frac{63}{5} = 12.6$

Thus average speed is 12.6 miles per hour

A credit card company uses these rules to calculate the minimum amount owed: For a bill of less than $100, the entire amount is

Mashutka [201]

Answer:

B. graph B

Step-by-step explanation:

The graphs of A,B,C and D are attached below.

Let x represent the credit amount and y represent the minimum amount due.

For a bill of less than $100, the entire amount is due. That is for 0 ≤ x < $100, y = x

For a bill of at least $100 but less than $500, the minimum due is $100. That is for $100 ≤ x < $500, y = 100

For a bill of at least $500 but less than $1,000, the minimum due is $300. That is for $500 ≤ x < $1000, y = $300

For a bill of $1,000 or more, the minimum due is $500. But the credit limit is $2000. That is For $1000 ≤ x < $2000, y = $500

The graph that shows the minimum amount due for a credit amount of x is graph B
