Answer:
67°F
Step-by-step explanation:
-4-63 = - 67°F
Therefore temperature difference=67
They both are correct <span>because adding two numbers that are opposites is equivalent to adding zero.
I had the same question on my quiz.</span>
To find the area of the cylinder we need to find its volume first. Remember that the formula for the volume of a cylinder is

where:

is the volume

is the radius

is the height
From the question we know that

and

. Lets replace those values in our volume formula:

Now we can solve for

to find our radius:




Now that we know the radius, we can use the formula for the area of a cylinder

where:

is the area

is the radius

is the height
We know now that

and

, so lets replace those values in our area formula:



We can conclude that the area of a cylinder that has a volume of 175 cubic units and a height of 7 units is
174.07 square units.
Answer:
17.5
Step-by-step explanation:
We know there are a total of 36 marbles. We also know 24 out of 36 are black and 12 out of 36 are blue. A ratio is pretty much a division problem... The problem wants the 24 black marbles over the 12 blue marbles. So, 24/12 = 2/1. Now, what this means is that for every 2 black marbles, there is one 1 blue marble. Good luck!
