Well first do 20 children minus 8 girls to find how many boys there are:
20-8=16
So there are 16 boys. Therefore we can write the ratio of girls to boys as:
8/16
Then we can simplify this ratio by dividing it by 8 to get:
1/2
So the answer is the ratio of girls to boys in the group in simplest form is 1/2.

Joseph's lunch at a restaurant costs $13.00 without tax. He leaves the waiter a tip of 17% of the cost of the lunch, without tax
ryzh [129]

Answer:

The total cost of the lunch including the tip is $15.21.

Step-by-step explanation:

To find the total cost of the lunch including the tip, first, you need to calculate 17% of the price of the lunch as the statement indicates that that is the tip Joseph leaves the waiter:

$13*17%=$2.21

Now, you need to add that amount to the price of the lunch:

$13+$2.21=$15.21

According to this, the answer is that the total cost of the lunch including the tip is $15.21.

Loto begins at his back door and walk 8 yards east, 6 yards north, 12 yards east, and 5 yards north to the barn door. About how
KonstantinChe [14]

If he could walk directly from the back door to the barn door, he would walk 10.2 yards less.

First, let's define our coordinate axis, I will use north as the y-axis and east as the x-axis.

So let's assume that Loto begins at the point (0, 0).

Then:

  • He moves 8 yards east, to: (8yd, 0)
  • He moves 6 yards north, to: (8yd, 6yd)
  • He moves 12 yards east, to: (20yd, 6yd)
  • He moves 5 yards north, to: (20yd, 11yd)

So he walked a total of 8yd + 6yd + 12yd + 5yd = 33yd

So he just moves from (0, 0) to (20yd, 11yd), thus the displacement is:

D  =\sqrt{(20yd - 0yd)^2 + (11yd - 0yd)^2}  = 22.8ft

So, if he could walk directly he would only walk 22.8 ft

The difference is:

33yd - 22.8yd = 10.2 yd.

He would walk 10.2 yards less if he could walk directly from the back door to the barn door.
