Answer:

[tex]$\text{P(Choose Cab Once)}=\frac{4}{9} $[/tex]

Step-by-step explanation:

In the morning Elizabeth has three transportation options to work.

It is [tex]$\frac{1}{3} $[/tex] :

In the evening Elizabeth has the same three transportation options to go home.

It is [tex]$\frac{1}{3} $[/tex] again.

But if we consider that she will take the cab once, the options will change to [tex]$\frac{2}{3} $[/tex] because now she can choose 2 options out of 3.

[tex]$\text{P(no cab) }= \frac{2}{3} $[/tex]

In order to use the cab once, we have two options:

She will use the cab in the morning or she will use the cab in the evening:

First route (cab in the morning):

[tex]$\text{Route 1}=\text{P(Choose Cab) } \cdot \text{P(Choose another one)} $[/tex]

[tex]$\frac{1}{3} \cdot \frac{2}{3} $[/tex]

Second route (cab in the evening):

[tex]$\text{Rote 2}=\text{P(Choose another one) } \cdot \text{P(Choose Cab)} $[/tex]

[tex]$\frac{1}{3} \cdot \frac{2}{3} $[/tex]

We have two routes, so

[tex]\text{P(Choose Cab Once)}=\text{Route 1}+\text{Route 2}[/tex]

[tex]$\text{P(Choose Cab Once)}=\frac{1}{3} \cdot \frac{2}{3} +\frac{1}{3} \cdot \frac{2}{3} $[/tex]

[tex]$\text{P(Choose Cab Once)}=\frac{2}{9} \cdot \frac{2}{9} $[/tex]

[tex]$\text{P(Choose Cab Once)}=\frac{4}{9} $[/tex]

Answer:

36 cm

Step-by-step explanation:

The area of a square is given by

A = s^2

81 = s^2

Take the square root of each side

9 =s

We want the perimeter

P =4s

P= 4*9

P = 36

Answer:

[tex]12\sqrt{2}[/tex]

Step-by-step explanation:

The formula for diagonal of the square:

[tex]d=\sqrt{2} a[/tex]

[tex]d=\sqrt{2} \times 12[/tex]

Answer:

For a the answer is 1/20 or 5%. For b the answer is 6/20 or 30%.

Step-by-step explanation:

a) There are 20 spots the dart can land on. To land on one specific spot, it would be 1/20. 1 spot out of 20 spots.

b) There are 20 spots the dart can land on. To land on any of the 6 spots, it would be 6/20. 6 spots out of 20 spots.

Answer:

10 ft

Step-by-step explanation:

Square root of 100 = 10

Answer:

10 feet

Step-by-step explanation:

To find the length of a square side using the area, what you need to do is find the square root of the area because a square area is the side length squared soooo.

[tex]\sqrt{100} =10[/tex]

25 = 5*5 and 9 = 3*3, which we can exploit to write

[tex]25^x-9^y=(5^2)^x-(3^2)^y=5^{2x}-3^{2y}=(5^x)^2-(3^y)^2[/tex]

so that this expression is actually a difference of squares. We can factorize this to get

[tex](5^x-3^y)(5^x+3^y)=18[/tex]

and given that [tex]5^x-3^y=3[/tex], we divide both sides by this to get

[tex]5^x+3^y=\dfrac{18}3=\boxed{6}[/tex]

Answer:

Step-by-step explanation:

1) The advertisements boast that 25% of the cereal in each box is almonds. It means that the percentage of the other cereals in the box is 100 - 25= 75%

Therefore, the portion of each box that is not almonds is 75/100 = 0.75

2) The advertisements boast that 25% of the cereal in each box is almonds. If each box contains 12 cups of cereal, then the number of cups of almonds in each box is

25/100 × 12 = 3 cups

3) if each box contains 12 cups of cereal, and 4 cups are oats, then the percentage of each box that is oats is

4/12 × 100 = 33.33%

Answer:

56 cubic inches

Step-by-step explanation:

Volume of cube box = 6^3 = 6 *6*6 = 216 , Volume of rectangular box = 10*4*4 = 160 . Difference = 216 - 160 = 56 cubic inches. 56 cubic inches greater is the volume of the cube-shaped box than the rectangular box.

Answer:

Step-by-step explanation:

cube volume=side^3

given that the side is 6, the volume is 6^3 or 216 cubic inches

volume regular rectangular prism=length times width times height

given that length=10, width is 4 and height is 4, volume=10*4*4=160 cubic inches

how much greater

216-160=56

it is 56 cubic inches greater

0.107

= 0.107/100 × 100 = 0.107 %

Answer:

40

Step-by-step explanation:

If you divide 30 by three, you get the 10%, which is 4, you multiply the 10% by ten to get the 100%, and you get 40. Hope this helps:)

Answer:

5 units

Step-by-step explanation:

I used the pythagorean theorem (a^2 + b^2 = c^2) to find the answer. I put 3 in a and 4 in b. I squared them and got 9 + 16 = 25. I found the square root of 25 which is 5 and that is my answer.

Answer:

The vertices of ABCD:

A ( - 3, 1 )

B ( 4 , - 3 )

C ( 1, 3 )

D ( - 1 , 4 )

∴ ( 4 x,  4 y ):

A ` ( - 12, 4 )

B ` ( 16, - 12 )

C ` ( 4, 12 )

D ` ( - 4 , 16 )
