Answer:
<h2>16.26</h2>
Step-by-step explanation:
Pythagorean Theorem | a^2 + b^2 = c^2
1) Plug in a & b
<h2>11^2 + 12^2 = c^2</h2>
2) Rewrite
<h2>c =

</h2>
3) Solve
<h2>c = 16.2788206</h2>
4) Round
<h2>16.26</h2>
Given, the density of a particular brand of gasoline = 0.737 g/ml.
13.4 gallon of tank given. We have to find the mass of gasoline to fill the tank.
First we will convert 13.4 gallon to ml.
We know that 1 gallon = 3.78541 litre
And 1 litre = 1000 ml
So we can write 1 gallon =
= 3785.41 ml.
13.4 gallon =
ml = 50724.494 ml.
Let's take there is x grams of gasoline
We know that density = (mass/ volume) = 
So we can write,

To find x we will multiply both sides by 50724.494. we will get,



So we have got the required answer.
Mass of gasoline = 37383.95 grams.
You have 40/16
simplified by 8 and you have 5:2
so the answer is d. 5:2
It would be -15.4 rounding to the nearest hundredth
Answer:
You keep them if you test 3 and all pass.
There are 18 good ones and 6 bad (making 24)
Chance of first passing is 18/24
If it passes, there are now one less good and one less total.
Chance of second passing is 17/23
If it passes, there are now one less good and one less total.
Chance of second passing is 16/22
Total is (16 x 17 x 18) / (22 x 23 x 24) = about 0.4 (0.403162055 is you really want to know).
So probability all are ok is 0.4
Thus probability you find at least one bad one is 0.6
Hope this helps you out!
