Answer:
13.63 miles per hour
Step-by-step explanation:
100 yards / 15 sec converted to miles per hour
<u>100 yards</u> x <u> 60 sec</u> x <u> 60 min</u> x <u> 1 mile </u> = 13.63 miles/hr
15 sec 1 min 1 hr 1760 yards
the mistake on Mrs Dukes is the conversion from miles to yards.
1 mile = 1760 yards NOT 5280 yards
That'd be : 28.8 . I hope this helps. This is it step by step.
60/x=100/48
<span>(60/x)*x=(100/48)*x </span>
<span>60=2.08333333333*x
</span>(2.08333333333) to get x
<span>60/2.08333333333=x </span>
<span>28.8=x </span>
<span>x=28.8</span>
5.5*3.14 = 17.27, which is already rounded to the nearest hundredth
Answer:
1. Arc BC = 78°
2. Arc ABC = 180°
3. Arc ADB = 258°
4. Arc EC = 102°
Step-by-step explanation:
Question 1 explanation: Since ∠AFE and ∠CFB are vertical angles, that means their angle measure is equal, so Arc BC has an angle measure of 78°.
Question 2 explanation: Because AC is the diameter of circle F, this means that the angle measure of Arc ABC is 180°.
Question 3 explanation: Since the angle measure of AC is 180° and ∠AFE and ∠EFD are 78° and 54° respectively, that means Arc DFC has an angle measure of 48°. Because you already know ∠CFB is 78°, that means Arc ADB has an angle measure of 258°.
Question 4 explanation: You already know Arc DFC is 48°, so Arc EC has an angle measure of 102°.
