Answer:

1. There is 1/9th chance that you'll get a multiple of 3 twice.

2. There is 2/3rds chance that you'll get a black ball.

Step-by-step explanation:

There is 1/3 chance that when you roll a dice once, you'll get a multiple of 3, so when you roll twice, there will be a (1/3)*(1/3) chance that you will get a multiple of 3 twice. (1/3)*(1/3)=1/9, so therefore, there is 1/9th chance that you will roll a multiple of 3 twice.

For every 1 white ball, there are 2 black balls. The ratio for black balls to white balls is 2:1. That means that there is 2/3rds chance that you will get a black ball.

sergeinik [125]

Answer:

£12.25

Step-by-step explanation:

Using unit rate:

$\frac{\text{Price}}{\text{Tickets}}=\frac{208.25}{17}=\frac{208.25/17}{17/17}=\frac{\boxed{12.25}}{1}$

£12.25 should be the correct answer.

Samantha has 54 beads. Amanda has twice as many beads as Samantha. They are making bracelets it takes 8 beads to make a bracelet

wlad13 [49]

Answer:

On combining the beads they can make 20 bracelets.

Step-by-step explanation:

The number of beads Samantha has = 54 beads

Number of beads Amanda has = 2 x( Number of beads Samantha has)

= 2 x 54 = 108 beads

The total number of beads Amanda and Samantha has

= 54 beads + 108 beads

= 162 beads

Number of beads required to make 1 bracelet = 8 beads

Now, $\textrm{The number of bracelets made} = \frac{\textrm{Total number of beads they both have}}{\textrm{Beads required to make 1 bracelet}}$

= $\frac{162}{8} = 20.25$ ≈ 20

or, the total number of bracelets they can make is 20.

Hence, on combining the beads they can make 20 bracelets .

Please help me find the total area of the composite figure below (geometry)

Akimi4 [234]

Answer:

lw + $\frac{1}{2}$ × π × $(\frac{l}{2} )^{2}$ ⇒ Answer D is correct

Step-by-step explanation:

First, let us find the area of the semi-circle.

Area = $\frac{1}{2}$ × π × r²

Given that,

diameter of the semi-circle is ⇒ l

∴ radius ⇒ l / 2

Let us find it now.

Area = $\frac{1}{2}$ × π × r²

Area = $\frac{1}{2}$ × π × $(\frac{l}{2} )^{2}$

Secondly, let us find the area of the rectangle.

Area = length × width

Given that,

length ⇒ l

width ⇒ w

Let us find it now.

Area = length × width

Area = l ×w

Area = lw

And now let us find the total area.

Total area = Area of the rectangle + Area of the semi - circle

Tota area = lw + $\frac{1}{2}$ × π × $(\frac{l}{2} )^{2}$
