What is the adult to child ratio of 8:5 if 390 attend how many are children

1 answer:

6 0

1. 8+5=13

2. 13 x 3 x 10 = 13 x 30 = 390

Using the information above transform the ratio 8:5.

8 x 30 : 5 x 30

If you do this, you'll end up with the ratio:

240 : 150

This means that 240 adults attended whilst 150 children attended.

Answer:

∠1 - 40°

Step-by-step explanation:

∠1 - 40°

b/c it's a right triangle and we have two angles given, 50° and 90°. Add them and subtract by 180° and get 40°.

∠2 - 140°

b/c an exterior (outside) angle is equal to the two most isolated / farthest angles added. The two most is angles are 105° and 35°, add them and get 140°.

∠3 - 40°

b/c ∠'s 1 and 3 are vertical angles meaning they're equal so since ∠1 is 40°, so is ∠3.

∠4 -

b/c ∠' s 2 and 4 are vertical angles meaning they're equal so since ∠2 is 140°, so is ∠4.

∠5 - 35°

b/c we have two angles, 105° and 40°. Add them and subtract by 180° and get 35°.

I hope that helps you out!!

pogonyaev

The equation given is:

c(x) = 4/3x + (-4)

Plug in 3 and solve:

c(3) = 4/3(3) + (-4)

c(3) = 12/3 + (-4)

c(3) = 4 + (-4)

Answer: c(3) = 0

b.) Team A: 6 m

Team B: 8 m

Team C: 7 m

Step-by-step explanation:

The size of the plot Team A wants = 36 square meters

The size of the plot Team B wants = 64 square meters

The size of the plot Team C wants = 49 square meters

a. The outline of the garden is attached

b.) The dimensions of each side of the needed plot of land by the three teams

For team A we have;

The shape of the needed plot of land = Square

The size of the needed plot of land = 36 m²

The dimension of each side of the needed plot of land = 6 m

The dimensions of each side of the needed plot of land for team A = 6 m

For team B we have;

The shape of the needed plot of land = Square

The size of the needed plot of land = 64 m²

The dimensions of each side of the needed plot of land = 8 m

The dimensions of each side of the needed plot of land for team B= 8 m

For team C we have;

The shape of the needed plot of land = Square

The dimensions of the needed plot of land = 49 m²

The dimensions of each side of the needed plot of land for team C= 7 m

c.) The minimum dimension of the garden plot are;

Length: 15 m

Width: 13 m
