First pear            Second pear      probability

green (3/7)---------green (2/6)         (3/7)*(2/6) = 1/7
                  ---------red (4/6)             (3/7) *(4/6) = 2/7

red (4/7)-------------green (3/6)        (4/7)*(3/6) = 2/7
             -------------red (3/6)             (4/7)*(3/6) = 2/7
                                                     -------------------------
                                                     1/7 + 2/7 + 2/7 + 2/7 = 1

The probailities that two are green are: 1/7

The probabilities that one is green and the other is red are:2 /7 + 2/7 = 4/7

The probabilities that two are red are: 2/7

A regular hexagonal prism has a volume of 160 cubic meters. Its base has a perimeter of 30 meters and an area of 64 square meter
valkas [14]
We know that

[volume of a <span>regular hexagonal prism]=[area of the base]*height
height=volume/area of the base
h=160/64-----> 2.5 m

[surface area </span><span>hexagonal prism]=2*[area of the base]+[perimeter of base]*h
</span>[surface area hexagonal prism]=2*[64]+[30]*2.5----> 203 m²

the answer is
203 m²

statuscvo [17]

9514 1404 393

Answer:

  5, 10, 20

Step-by-step explanation:

Suppose the three numbers are x, 2x, and 4x. Then they have the required ratios. After the transformation, we have ...

  ((x+3) +(4x -8))/2 = 2x . . . . . 2nd term is average of 1st and 3rd

  5x -5 = 4x   ⇒   x = 5

The original numbers are 5, 10, 20.

_____

After the adjustment, the arithmetic sequence is 8, 10, 12.

Please help with this algebra question
zhannawk [14.2K]
Perimeter: P=24 ft
Lenght: L
Width: W

The length is 2 ft longer than the width:
(1) L= W+2 ft

Perimeter: P=2(W+L)
P=24 ft
2(W+L)=24 ft
Dividing both sides of the equation by 2:
2(W+L)/2 =(24 ft)/2
(2) W+L=12 ft

We have a system of 2 equations and 2 unkowns:
(1) L=W+2
(2) W+L=12

Using the method of substitution: Replacing L by W+2 in the second equation:
(2) W+L=12
W+(W+2)=12
W+W+2=12
2W+2=12

Solving foe W
2W+2-2=12-2
2W=10
Dividing both sides of the equation by 2:
2W/2=10/2
W=5

Replacing W by 5 in the first equation:
(1) L=W+2
L=5+2
L=7

Answers:
What is the width?  5 ft
What is the length? 7 ft
