What time between 6pm and 6:30 pm the hour and minutes hands be exactly 125* degree apart

vladimir2022 [97]

Answer:

6:10pm

Step-by-step explanation:

At 6:00 the hands are 180° apart.

The hour hand moves 1/12 of circle per hour = 30° per hour = 0.5° per minute.

The minute hand moves 1/60 of the circle per minute = 6° per minute

Angle between the hands decreases by 6-0.5 = 5.5° per minute.

180 - 5.5t = 125

t = 125/5.5 = 10 minutes

The hands are 125° apart at t minutes after 6:00, or 6:10.

What is the circumference of the circle if r = 3.5 feet? Use 22 7 for π. A) 5.5 feet B) 11 feet C) 22 feet D) 38.5 feet

Liono4ka [1.6K]

Well, to find the circumference of a circle, we can use the formula
C=2 $\pi$ r.
So just plug in 3.5 into the formula.
C=2 $\pi$ 3.5.
Multiply and we get C=21.99. which is about 22
So our answer would be C. 22 feet.
Hope I helped!

8(7n-2) -6(7n+1)<br><br> Explain please

Verizon [17]

Answer:

<h2>8(7n - 2) - 6(7n + 1) = 14n - 22</h2>

Step-by-step explanation:

8(7n - 2) - 6(7n + 1)

use the distributive property: a(b + c) = ab + ac

= 8 · 7n + 8 · (-2) + (-6) · 7n + (-6) · 1

= 56n - 16 - 42n - 6

combine like terms

= (56n - 42n) + (-16 - 6)

= 14n - 22
