1.5 I did it with Pythagoras theorem

Answer:

x = 1.5 ft.

Step-by-step explanation:

This is a right triangle, of course, so the Pythagorean Theorem applies.

Looking at this figure, I can see that the hypotenuse is 3.9 feet and one of the legs is 3.6 and feet.

The only side length missing is the second leg.

Here, I am solving for the second leg.

a^2+b^2=c^2

3.6^2+x^2=3.9^2

12.96 + x^2=15.21

15.21-12.96=2.25

x^2=2.25

x=1.5

Therefore, the length of the missing side is 1.5 ft.

My brother needs help and I have load of hw plz help

The ratio indicates that there are 8 dolls for every 7 teddy bears. That means that if there is 16 dolls, then there is 14 teddy bears. And that if there is 24 dolls, then there is 21 teddy bears. You could continue this pattern, or you could divide and multiply. If you have 160 dolls, then do 160/8 to simplify the ratio. You get 20. So if there is (8x20) dolls, then there is (7x20) teddy bears. 7x20 is 140, so there are 140 teddy bears.
