Answer:

The number of large size candles sells are 12 and the number of small size candles are 5 .

Step-by-step explanation:

As given Sia sells large candles for $3 each and small candles for $2 each.She sold 17 candles for $46.00.Let us assume that the large size candle sells are x .Let us assume that the small size candle sells are y.             Equation becomes

x + y = 17

3x + 2y = 46

Multiply x + y = 17 by 3 and subtracted from 3x + 2y = 46 .

3x - 3x + 2y - 3y = 46 - 51

-y = - 5

y = 5

Put in the equation x + y = 17 .

x + 5 = 17

x = 17 - 5

x = 12

Therefore the number of large size candles sells are 12 and the number of small size candles are 5

A bicycle tire has a diameter of 62 \text{ cm}62 cm62, start text, space, c, m, end text. What is the distance the bicycle tire
navik [9.2K]

Answer:

The distance bicycle tire travels is <u>1946.8 cm</u>.

Step-by-step explanation:

Given:

Diameter of bicycle tire = 62 cm.

The bicycle tire travels in 10 revolutions.

Now, to find the distance the bicycle tire travels in 10 revolutions.

Diameter = 62 cm.

Radius (r) = \frac{Diameter}{2}=\frac{62}{2}=31\ cm.

So, we get the circumference first by putting formula:

Circumference =2\pi r

Circumference =2\times 3.14\times 31\\\\Circumference =194.68\ cm.

Thus, we get the <u><em>circumference of tire 194.68 cm.</em></u>

<u><em>Number of revolutions the tire travels = 10.</em></u>

Now, to get the distance the bicycle tire travels we multiply circumference of tire by number of revolutions the tire travels:

194.68\ cm\times 10\\\\=1946.8\ cm.

Therefore, the distance bicycle tire travels is 1946.8 cm.

  • Given - <u>a </u><u>cone </u><u>with </u><u>base </u><u>radius </u><u>9</u><u>m</u><u>m</u><u> </u><u>and </u><u>height </u><u>1</u><u>3</u><u> </u><u>mm</u>

  • To calculate - <u>volume </u><u>of </u><u>the </u><u>cone</u>
