Answer:
Step-by-step explanation:
you have a special triangle 30-60-90
the ration in this traingle is x, x
, 2x, where 2x is the hypothenuse
the hypothenuse is 12
x=12/2=6
the other leg is 6
=10.39
For the first question, it would be D:

÷ 9. This is because to solve a division problem with fractions, you would need to multiply the first fraction by the reciprocal of the second fraction. For the second question, the answer would be D: 32. This can be solved by dividing 8 by

or 0.25. For the third question, it would be D.

. This can be solved by dividing

by 3. For the fourth question, the answer would be

. This can be found by flipping the 4, which would make it look like

, and multiplying it by

. For the last question, 1 would be B, 2 would be C, 3 would be C, and 4 would be A.
Hope this helps ^-^

Step-by-step explanation:
<u>Answer:</u>
Piston displacement = 84.8
<u>Step-by-step explanation:</u>
We will find the volume of the cylinder in order to find the piston displacement.
Here, (bore = diameter, so r = diameter/2) (height = stroke)
Volume =
= 21.2 cubic units
Since the engine has 4 cylinders, so we will multiply the piston displacement by 4 to get:
Piston displacement =
= 84.8
