Perimeter=2(length(x)+width(y))

16=2(l+w)

16=2(5+3)

5+5+3+3=16

length (2 sides) =5+5=10
width (2 sides) =3+3=6

Crank

Answer:

Step-by-step explanation:

Let N be the total number of spins.

Probability of A on Red and B on Red = 0.5 x 0 .6 = 0.3 (top branch of tree)

Therefore with N spins, the estimated number of times spinner A and spinner B land on red is 0.3N and we are given this as 84

So 0.3N = 84
N = 84/0/3 = 280

The probability of spinner A on blue and spinner B on blue is 0.5 x 0.4 = 0.2 (lowest branch of tree)

For 280 spins, the estimated number of times that both spinners land on blue is given by 0.2 x 280 = 56

Answer:

Order from greatest to least: 10.5, $3\pi +1$ , $\sqrt{105}$

Step-by-step explanation:

step 1 simplify each number

3π + 1 = 10.4247779

*round to the nearest tenth*

3π + 1 = 10.4

$\sqrt{105} =10.2469507$

*round to the nearest tenth*

$\sqrt{105} =10.2$

10.5 = 10.5

Now that we have simplified each number we can easily put them in order from greatest to least

10.5 is the greatest number

10.4 is the middle number

10.2 is the lowest number

so 10.5, 10.4, 10.2

Now we put them back in the original form

10.5 = 10.5

10.4 = 3π + 1

10.2 = $\sqrt{105}$

Your answer is

10.5 , 3 $\pi$ + 1, $\sqrt{105}$
