How many square centimeters for the area?
we are given that out of 100 light bulbs, 7 of them were defective. We can assume that out of every 100 lightbulbs, 7 of them will be defective.
we can write this as a ratio of defective lightbulbs to total
7:100
we want to see how many defective there are when we have 3000 bulbs, to do this we can multiply both numbers by 30
7 * 30 = 210
100 * 30 = 3,000
our new ratio is now
210:3,000
so we are now able to say that in a lot of 3,000 lightbulbs, there would be 210 defective bulbs.
hope this helped!
Answer:
Step-by-step explanation:
Given
The position of badwater is negated because it is below sea level
The interpretation of the question, is to calculate the distance between the two given points.
This is calculated as:
Open bracket
<em>Hence, the distance between both is 11325ft</em>
7(2x + 3) + 2(2x + 4)
Distribute/multiply 7 into (2x + 3), and distribute 2 into (2x + 4)
(2x(7) + 3(7)) + (2x(2) + 4(2))
14x + 21 + 4x + 8 Combine like terms
18x + 29
