Answer:
x = 12
Step-by-step explanation:
Missing length of the segment is the altitude of the right triangle.
Based on the geometric mean theorem, we would have the following:
h = √(ab)
Where,
h = x
a = 16
b = 9
Plug in the values:
x = √(16*9)
x = √144
x = 12
758, you go by the one's number first. 5 and up rounds up to 10, so we goto the next number 50, 5 rounds up to 10, so up from 50 goes to the next hundred. 800 is the nearest hundred.
Answer:
<h2>
2ab(a+3b)</h2>
Step-by-step explanation:
Factor out common term : 2ab

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!
