Answer:

8

Step-by-step explanation:

Ok so 3 copies = 40 cents.

75 - 40 = 35.

We only have 35 cents left.

The highest number that can go in 35 with 7 is 5.

Oir original 3 copies + our 5 copies is 8

I did this in my head so sorry if I'm totally wrong.

What is the value of k if 7k" minutes past nine" is the same as 8k" minutes to ten"?
schepotkina [342]

Answer:

4 minutes

Step-by-step explanation:

The value of 7k "minutes past nine" is the same as 8k" minutes to ten".

Since there are 60 minutes in an hour and 9 and 10 fall in between the same hour, this means that:

7k = 60 - 8k

7k + 8k = 60

15k = 60

k = 60 / 15

k = 4 minutes

Virty [35]
Law of sines can be used to solve this problem:

(note - let x represent the missing side length.)

1. set up proportion.
sin 90°/25 = sin 55<span>°/x

2. solve.
(x) sin 90</span>° = (25) sin 55<span>°

(x) sin 90 </span>°/sin 90° = (25) sin 55° / sin 90<span>°
</span>
x = 20.4788011072
