A string of decorative lights is 28 feet long. The first light on the string is 16 inches from the plug. If the lights on the string are spaced 4 inches apart, how many lights are there on the string?
Find out what length of the string will have lights on it (some of it has no lights on it as said in the question). See how many 4 inches are then in that space. Don't forget to include the first bulb after you work out the total.
still don't get it
80
28x12=330 inches
336-16=320 inches
320 divide 4 = 80 lights

26ft = how many inches
Take away the piece of string with no lights (the 16 inches)
See what's left and divide by 4 inches (as each light is placed 4 inches apart).
Add 1 at the end as you didn't include the first bulb.
When Jamie car moves forward such that each tire makes one full rotation the car has traveled 72 inches how many full rotation will the tires need to make for Jamie's car to travel 10 yards
The answer is simple
81 Lights
To find the number of lights on the string, we need to determine the total length covered by the lights and divide it by the spacing between the lights.
First, convert the length of the string from feet to inches:
28 feet = 28 * 12 inches = 336 inches
Now let's subtract the distance between the plug and the first light from the total length covered by the lights:
336 inches - 16 inches = 320 inches
Finally, divide the remaining length by the spacing between the lights to find the number of lights on the string:
320 inches / 4 inches = 80 lights
Therefore, there are 80 lights on the string.
