We have to calculate the perimeter of the figure to the nearest tenth of a millimeter. This figure is made of a rectangle and a half of a circle. The first figure has the perimeter: 3 + 6 + 3 = 12 mm. The second figure has the perimeter: 2 * Pi * r / 2 = Pi * r ; and the radius : r = 6/2 = 3 mm. So Pi * 3 = 3.14 * 3 = 9.42. Fimally : 12 + 9.42 = 21.42 or 21.4 to the nearest tenth. Answer: C. 21.4 millimeters<span>. </span>
Answer:
6 mph
Step-by-step explanation:
Difference in distance
= 15 - 12
= 3 mi
time taken
= 30 mins
= 1/2 hour
Speed
= 3 ÷ 1/2
= 6 mph
Answer:
Bryden will get a total of $20 for this four quarters
Step-by-step explanation:
Here, we have a collector offering to buy state quarters for 2,000% of their face value.
Now, we have 4 state quarters with the value of 1 being 25 cents.
Since 1 has a value of 25 cents, then four will have a face value of 25 cents * 4 = 100 cents or better still $1
Now, the offer is 2000%
So the amount to be paid in dollars will be 2000% of $1.
Mathematically, that would be;
2000/100 * 1 = 2000/100 = $20
