Answer:
45 green marbles
Step-by-step explanation:
Roberto overtakes Juanita at the rate of (7.7 mi)/(11 h) = 0.7 mi/h. This is the difference in their speeds. The sum of their speeds is (7.7 mi)/1 h) = 7.7 mi/h.
Roberto walks at the rate (7.7 + 0.7)/2 = 4.2 mi/h.
Juanita walks at the rate 4.2 - 0.7 = 3.5 mi/h.
_____
In a "sum and diference" problem, one solution is half the total of the sum and difference. If we let R and J be the respective speeds of Roberto and Juanita, we have
R + J = total speed
R - J = difference speed
Adding these two equations, we have
2R = (total speed + difference speed)
R = (total speed + difference speed)2 . . . . . as computed above
Answer:
37 degrees
Step-by-step explanation:
The angles within a triangle always add up to 180 degrees. Right angles are always 90 degrees. 53 + 90 = 143 degrees. 180 - 143 = 37 degrees
The value of the term in the series will be equal to 3 + 12 +48 + 192 after calculation.
<h3>What is summation?</h3>
In mathematics, the summation is the addition of a sequence of any kind of numbers, called addends or summands.
Now we have a given term
By solving the above term;
Hence the value of the term in the series will be equal to 3 + 12 +48 + 192 after calculation.

<u>First what I did was find how much each pound would cost per different package. </u>
<u>So starting off with the 3 pound package. I did 2.49 divided by 3 to find out how much each pound would weigh. </u>
2.49 / 3 = 0 . 83
<u>So each pound in the 3 pounded package would cost $0.83. </u>
<u>Now to see how much the 8 pound package would cost. Just like the 3 pound package I had to find how much each pound would weigh. So I divided 6.49 by 8. </u>
6.49 / 8 = 0.81125
<u>So looking at the results the 3 pound package would be the best option. You are getting more for less. </u>
