Answer:
The 12 pack has a better value.
Step-by-step explanation:
1. create a ratio table.
you want to know how much the 4 pack would cost if it was a 12 pack.
you can see the ratio table in the picture above.
As you can see, when the 4 pack equals $7.68, making it a 12 pack will equal $23.04.
<em>Then</em><em>,</em><em> </em><em>compare</em><em> </em><em>2</em><em>3</em><em>.</em><em>0</em><em>4</em><em> </em><em>to</em><em> </em><em>2</em><em>2</em><em>.</em><em>3</em><em>2</em><em>.</em><em> </em>
<u>In</u><u> </u><u>conclusion</u><u>,</u><u> </u><u>the</u><u> </u><u>1</u><u>2</u><u> </u><u>pack</u><u> </u><u>has</u><u> </u><u>a</u><u> </u><u>better</u><u> </u><u>value</u><u>.</u>
Answer:
38.60 mph
Step-by-step explanation:
Average speed = total distance / total time
44 mph = (70 mi + 60 mi) / t
t = 2.95 hr
The time spent during the first 70 miles is:
d = rt
70 mi = (50 mph) t
t = 1.4 hr
So the time spent during the last 60 miles is:
t = 2.95 hr − 1.4 hr
t = 1.55 hr
So the average speed during the last 60 miles is:
d = rt
60 mi = r (1.55 hr)
r = 38.60 mph
The bicycle costs $30 and Hugo finishes paying after 15 weeks. When he has paid for the bike, y=0 because he owes nothing. So -10=-2x+20, 2x=30, x=15. And the cost of the bike is 2×15=$30.
Answer:
Step-by-step explanation:
60 + (60 *.4) = 84 inches
60 - (60 * .4) = 36 inches
Answer:
Area of a regular decagon with a perimeter of 60 ft. = 277 squared ft
Step-by-step explanation:
Decagon has 10 sides So 60/10 = 6 (each side = 6ft )
The sum of the interior angles of a decagon is 1 440 degrees.
There are 10 equal isosceles triangles of base angles 72 degrees in a decagon
Each isosceles triangle can subdivided into 2 right-angled triangles with height h and base length = (6/2) = 3 cm and base angle 72 degrees.
Height of right-angled triangle h = 3 tan 72 ft.
Area of 1 right-angled triangle = (1/2)(3)(3 tan 72) = 13.85 squared ft
Area of decagon = 20 right-angled triangles = 277 squared ft
