<h3>Solution:</h3>

Radius = Diameter ÷ 2 = 13 ÷ 2 = 6.5 cm

Circumference = 2πr

→ Circumference = 2 × π × 6.5

→ Circumference = 13 π cm

Therefore, circumference of given circle = <u>13 π cm</u>

The graph represents a mechanic’s labor costs for a given number of hours of car repair.
ElenaW [278]

A graph is a way to represent a lot of data in such a visual format that it is easy for the user to understand the complete information in one go. The correct statement is A.

<h3>What is a graph?</h3>

A graph is a way to represent a lot of data in such a visual format that it is easy for the user to understand the complete information in one go. Usually, the line of the graph is a function that follows the graph.


As per the graph of the mechanic, the statement that best describes the relationship between the labor cost and the time for a car repair is that All repairs requiring 1 hour or less have the same labor cost.

Hence, the correct statement is A.

Point A is located at ​(4, 8)​ and point B is located at ​(14, 10)​ . What point partitions the directed line segment ​ AB⎯⎯⎯⎯⎯
andrew11 [14]

The 1:3 ratio means that the distance from A to the point is 1/4 of the distance from A to B.

The difference of y-coordinates is 10-8 = 2. 1/4 of that is 2·1/4 = 1/2, so the point of interest will have y-coordinate 8 + 1/2 = 8 1/2. This apparently corresponds to the first selection:

There are less than 200 apples in a box. It is known that 2,3,4,5, and 6 kids can share these apples evenly. How many apples can
bekas [8.4K]

Answer:

60/120/180

Step-by-step explanation:

Either of these would work because it must be an even number divisible by 2.

It must end in a zero : divisible by 5 but even.

It must be a multiple of 30 as 3 only goes into 10s at 30. And that takes care of the 6 too.

But 4 doesn't go into 30, so 60?….

Yes, 60 is divisible between 2, 3, 4, 5 and 6

But the question does not limit your answer to one solution.

I hope this helps! :)

The exact circumference of the circle is 7 \frac{49}{150} k m

The approximate circumference of the circle is 7.33 k m

Explanation:

The diameter of the circle is 2 \frac{1}{3} \mathrm{km}

Now, we shall find the circumference of the circle.

The formula to determine the circumference of the circle is given by

C=\pi d

Where C is the circumference , \pi is 3.14 and d=2 \frac{1}{3} \mathrm is the diameter of the circle.

The exact circumference of the circle is given by

\begin{aligned}C &=\pi d \\&=(3.14)\left(2 \frac{1}{3}\right) \\&=(3.14)\left(\frac{7}{3}\right) \\&=\frac{21.98}{3}\end{aligned}

Multiply both numerator and denominator by 100, we get,

C=\frac{2198}{300} \\C=\frac{1099}{150}

Converting \frac{1099}{150} into mixed fraction, we get,

C=7 \frac{49}{150}

Thus, the exact circumference of the circle is 7 \frac{49}{150} k m

The approximate value of the circumference can be determined by dividing the value \frac{1099}{150}

C=\frac{1099}{150}=7.327

C=7.33km

Thus, the approximate circumference of the circle is 7.33 k m
