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?

Answers

well if there is 28 feet, that would be (12x28) 336 inches, and 16 inches between the plug and the first light, there would be only 320 inches left for lights. therefore, if there are 4 inches between each light, we divide 320 by 4. the answer we get is 80. there are 80 lights.

Round 6.7493 to 2 significant figures

Answers

Answer:

6.75

Step-by-step explanation:

Since, when we rounded a decimal number to 2 significant figures,

We check the thousandth digit, ( third digit after decimal )

If thousandth digit is less than 5 then the hundredth digit ( second digit after decimal ) will be rounded to preceding number while if it is 5 or more than 5 then the hundredth digit will be rounded to succeeding number,

∵ 9 > 5

Hence, 6.7493 ≈ 6.75
