Isn't there no resistance between a light bulb that uses 15 watts of power when it is placed across a 15-volt battery?
-16 i think is the correct anwser because you take the old number then subtract the new number then divide the old one then multiply by 100
Answer:
13
Step-by-step explanation:
d = √((x_2-x_1)²+(y_2-y_1)²)
d = √(2--3)²+(-8-4)²
d = 13
To solve this we are going to use the formula for the volume of a sphere:
where
is the radius of the sphere
Remember that the radius of a sphere is half its diameter; since the first radius of our sphere is 24 cm,
. Lets replace that in our formula:
Now, the second diameter of our sphere is 36, so its radius will be:
. Lets replace that value in our formula one more time:
To find the volume of the additional helium, we are going to subtract the volumes:
Volume of helium=
We can conclude that the volume of additional helium in the balloon is
approximately <span>
17,194 cm³.</span>
Step-by-step explanation:
- The first reason is given. Since the question gave us those, we say its given.
- The second/third reason is also given
- The fourth reason is alt int angles. A transversal crosses through parallel lines AB and DE.
- The fifth is definition of a midpoint.
- The final is SAS
