Answer:
26π
Step-by-step explanation:
Hmm... This one is a little hard to understand because of the LaTeX.
Any way, way back to the question. A useful piece of information:
<u>The formula for finding the circumference of a circle is 2πr or π · d :</u>
We first need to find out what x is.
Since 2 times the radius is the diameter, we can set up our equation like this:
2(x + 6) = 3x + 5
Solving gives:
2x + 12 = 3x + 5.
We subtract 2x from both sides:
+12 = x + 5
Subtract 5:
So x = 7.
Now we can plug-and-chug:
7 + 6 = 13 times 2pi (this is the radius)
21 + 5 = 26 times pi.
<u>Check:</u>
When we check 13 (radius) times 2 should equal the diameter(26)
13 * 2 = 26.
So we are correct. The answer 26π is correct.
We know Bianca delivers 100 newspapers every 2 days.
So we must find out how many papers she delivers in 1 day.
100 ÷ 2 = 50
Bianca delivers 50 papers in 1 day.
Now we must multiply that by 7.
50 × 7 = 350
We get 350 papers per week.
The answer is 350.
Answer:
On Graph B, at 0 hours, the graph will be at 0 feet.
Then, the graph will increase until 1 hour, when the submarine reaches its deepest point.
At 1 hour, the height of Graph B will be 4000 feet.
Step-by-step explanation:
1,000 grams = 1 kilogram
2,000 grams = 2 kilograms
3,000 grams = 3 kilograms
4,000 grams = 4 kilograms
5,000 grams = 5 kilograms
.
