8 rock in 5 minutes

54 rocks / 8 rocks = 6.75

6.75 x 5 minutes = 33.75 minutes

Answer:

33 minutes and 45 seconds.

Step-by-step explanation:

We can easily set up a proportion...

He can paint 8 rocks in 5 minutes. He can paint 54 rocks in x minutes.

$\frac{8}{5} =\frac{54}{x}$

8 * x = 54 * 5

8x = 270

4x = 135

x = 33.75

So, it will take Ronnie 33 minutes and 45 seconds to paint 54 rocks.

Hope this helps!

Four times a number added to 7 times the number equals 44.

zysi [14]

If you're looking for the value of the number, then here's how:
Let's call the number x
4x + 7x = 44
11x = 44
÷ 11
x = 4
So the number you're looking for is 4, if you wanted to know something else then let me know!

Answer:

Therefore,

The length of the path traced by the outer tip of the minute hand in one hour, is 88 inches.

Step-by-step explanation:

Given:

The length of the minute hand of a clock is,

Which is as Radius,

Therefore,

Radius = r = length of the minute hand = 14\ inches

pi = 22/7

To Find:

The length of the path traced by the outer tip of the minute hand in one hour, will be One full rotation, that is

Circumference, C = ?

Solution:

Circumference, is given by,

$Circumference = 2\pi r$

$Circumference = 2\times \dfrac{22}{7}\times 14=88\ inches$

Therefore,

The length of the path traced by the outer tip of the minute hand in one hour, is 88 inches.
