Answer:
Step-by-step explanation:
The diameter of each curved path is 200 feet. Since the two curved semi circular paths are equal, they would form a circle. It means that the distance around the two semi circular paths would be the circumference of the circle. Formula for determining the circumference of the circle is π × diameter. It becomes
200 × 3.14 = 628 feet
Total distance around the track would be
300 + 300 + 628 = 1228 feet
5280 feet = 1 mile
1228 feet = 1228/5280 = 0.23 mile
If he runs around the track exactly 15 times, it means that the number of miles covered is
0.23 × 15 = 3.45 miles
Since he will collect $4.50 for every mile he runs, the amount of money that he collected is
4.5 × 3.45 = $15.5
Answer:
1 roll of ribbon, 1 package of buttons, and 3 packages of beads
Step-by-step explanation:
Use the information you found about how much each makes to answer the question.
Lynette will make 6 decorations.
Since 1 roll makes 6, she needs 1 roll.
Since 1 package of buttons makes 6, she needs 1 package.
Since 1 package of beads makes 2, she needs 3 packages.
Let's look at the corresponding ratios:
And we see that the three aren't equal.
Hence, $\Delta ABC$ and $\Delta EDC$ are not similar.
Answer:
66 cm
Step-by-step explanation:
Diameter (d) = 21 cm
Length of circumference is 2πr
2 π r and r is equal to 2 cm
I.e 12.5 cm
