Find the number of pieces that aren't red, by subtracting the red from the total:

11 - 5 = 6 are not red.

The probability is the number of none red, over the total number of pieces: 6/11

A club swimming pool is 21ft wide and 41ft long. The club members want a uniform width border around the pool. They have enough

oksano4ka [1.4K]

Answer-

Strip with 2.13 ft width can be used.

Solution-

A club swimming pool is 21 ft wide and 41 ft long.

Hence, the perimeter of the swimming pool is

$P=2(\text{Length}+\text{Width})=2(41+21)=2(62)=124\ ft$

The club members want a uniform width border around the pool.

They have enough material for 264 ft²

As they will cover the perimeter of the rectangular pool, so the length of the total used strip is equal to the perimeter of the swimming pool.

Let the width of the strip is x ft

So, the total area of the used strip is,

$A=\text{Length}\times \text{Width}$

Putting the values,

$\Rightarrow 264=124\times x$

$\Rightarrow x=\dfrac{264}{124}$

$\Rightarrow x=2.13\ ft$

Therefore, strip with 2.13 ft width can be used.

Jennifer has a taco stand.she found that her daily costs can be modeled by C(x)=x^2-40x+610. if she wants to keep her daily cost

Svetllana [295]

Plug in 300 for C(x), to get:
300= $x^{2} -40x=610$
Then subtract to get: 0= $0= x^{2} -40x+310$
Then use the quadratic formula and plug everything in. Use a calculator to simplify.

You'll get two answers: 29.486 and -0.513.
Since you can't sell "negative" tacos, use the positive solution

Two sizes of cans of beans are similar. The thickness of the walls and bases are the same in both cans. The ratio of their surfa

agasfer [191]

Answer:

It costs $0.216 to make smaller can and $0.324 to make larger can

Step-by-step explanation:

Given:

The ratio of the surface areas = 4:9

Area of smaller cans = 36 sq in

Cost = $0.006 per square inch

To Find:

how much does it cost to make each can = ?

Solution:

Lets the area of the larger can be x

the ratio is 4 : 9

then 4x = 9.(36)

4x = 216

$x = \frac{216}{4}$

x = 54

The area of the larger can is 54 sq in

Now the cost of making the smaller can = $36 \times 0.006$ = $0.216

The cost of making the Larger can = $54 \times 0.006$ =$0.324
