7 = 2(4) -1
7 = -4 +11
Well, there are 60 minute in an hour and 60 seconds in a minute so we can multiply 7 by 60 and then 60 again to find out answer.
7 times 60=420 times 60=25200

Answer:x = 12
because RHMO is a rhombus => MH⊥RO
=> m∠3 = 90°
⇒ 8x - 6 = 90°
⇔ 8x = 96
⇔ x = 96/8 = 12
Step-by-step explanation:

Answer:
1/2 π × d + d where d is the diagonal
Step-by-step explanation:
The perimeter of a circle is π × d where d is the diameter so half of that is 1/2 π × d. But If you are going to walk around a semicircle you need to go half way around the circle and then across a diagonal to get back to where you started so the perimeter is 1/2 π × d + d.
