Phil strung two sets of lights around the window of his store. The first set of lights blinks every 30s and the second every 45s

Amiraneli [1.4K]

Answer:

Every 90 seconds, the two sets of light blink together.

Step-by-step explanation:

Given that there are two sets of lights.

First light blinks at every 30s and

Second light blinks at every 45s

To find:

How often the sets of lights blink together?

Solution:

As per given statement,

First light blinks after 30s, 60s, 90s, 120s, 150s, 180s, ........

Second light blinks after 45s, 90s, 135s, 180s, .....

If we look at the common time, shown by underlining it, the two sets of light blink at the same time after 90s, 180s, ...... and so on.

So, the two lights blink together after every 90s.

This can also be solved by finding LCM (Least Common Multiple) of the two numbers i.e. 30 and 45.

Let us have a look at the factors of 30 and 45.

30 = 2 $\times$ 3 $\times$ 5

45 = 3 $\times$ 3 $\times$ 5

So, LCM = 2 $\times$ 3 $\times$ 3 $\times$ 5 = 90

So, after every 90s, the lights will blink together.

Emma is playing miniature golf. Her ball is 2 feet of the right-wall. The hole is 4 feet to the left of the wall. The distance a

GalinKa [24]

Answer:

She should aim 6 feet down the wall

Explanation:

The diagram attached sketches the situtation.

Since the angle with which the ball hits the wall is the same with which it bounces, angle β is the same for the two shown triangles.

Then, since both are right triangles, then all the angles are congruent and the triangles are similar. Hence, you can equal the ratios of the sides, to make an equation:

x/4 = y/2 ⇒ x = 2y

You have other equation:

x+ y = 18

Substitute

2y + y = 18

3y = 18

y = 18/3

y = 6 ← this is the distance down the wall where the ball should hit

x = 2(6) = 12

Then, she should aim 6 feet down the wall.

In converting 9 yards to inches, what unit (omit the number) would you place in the numerator of your ratio? Remember that there

mamaluj [8]

Answer:

inches

Step-by-step explanation:

The "to" unit goes in the numerator. (The "from" unit goes in the denominator.) Since we're converting to inches, the numerator of the conversion factor has units of inches.

_____

9 yd = 9 yd × (36 in)/(1 yd) = 324 in
