Answer:

d = 14

Step-by-step explanation:

\sin \: 45 \degree =  \frac{a}{7 \sqrt{2} }  \\  \\a = 7 \sqrt{2}  \sin \: 45 \degree  \\  \\ a =  7\sqrt{2}   \times  \frac{1}{ \sqrt{2} }  \\  \\ a = 7 \\  \\  \sin \: 30 \degree =  \frac{a}{d}  \\  \\  \frac{1}{2}  =  \frac{7}{d}  \\  \\ d = 2 \times 7 \\  \\ d = 14

VARVARA [1.3K]

Answer:

It’s 60miles

Step-by-step explanation:

We assume the trip is "d" miles and that the "extra hour" refers to the additional time that a current of 2 mph would add. That is, we assume the reference time is for a current of 0 mph.

The time with no current is ...

 time1 = distance/speed

 time1 = d/12 . . . . hours

With a current of 2 mph in the opposite direction, the time is ...

 time2 = d/(12 -2) = d/10

The second time is 1 hour longer than the first, so we have ...

 time2 = 1 + time1

 d/10 = 1 + d/12

 6d = 60 + 5d . . . . multiply by 60

 d = 60 . . . . . . . . . subtract 5d

The one-way distance is 60 miles.

Your Question:
<span>Laurie buys four bags of candy with 10 pieces of candy in each bag. Her father then gives her 5 more pieces of candy.

How many pieces will be left over, if any, after Laurie gives her friends the candy?
My Answer:
If Laurie has four bags with ten pieces in each bag, and if her father gives her five more pieces,  she would have forty-five pieces and if she has six friends and wants to share it equally with six friends. Each friend would get 7 pieces.
