A shoebox holds a number of disks of the same size. There are 5 red, 6 white, and 7 blue disks. You pick out a disk, record its color, and return it to the box. If you repeat this process 250 times, how many times can you expect to pick either a red or white disk?

Answer:

rational.

Step-by-step explanation:

Answer:

We are given the rule: the speed is the ratio between the distance and the time. So we have

s = d/t = 100/2.5

As a decimal, the answer is 1.83. As a fraction, it’s 11/6 and as a mixed number, it’s 1 5/6

Answer:

5-6i

Step-by-step explanation:

The complex conjugate root theorem states that if (a+bi) is a root, then (a-bi) must also be a root and vice versa.

We know that (5+6i) is a root.

Then by the above theorem, (5-6i) must also be a root.

Hence, our solution is (5-6i).

The answer is (B).

Answer:

The complete set of domain (x) and range values (y) is given by:

x                   y

-2                39

0                 13

3                  11

Step-by-step explanation:

Considering the function

[tex]f(x)=-8x+13[/tex]

As we know that the range of a function consists of the entire set of all possible resulting values of the dependent variable commanly called y or f(x), once we have substituted the domain.

Now

Putting x = -2 in f(x) to determine the range for the value x = -2

[tex]f(x)=-8x+13[/tex]

[tex]f(-2)=-8(-2)+13=16+13=39[/tex]

Putting x = 0 in f(x) determine the range for  the value x = 0

[tex]f(x)=-8x+13[/tex]

[tex]f(0)=-8(0)+13=0+13=13[/tex]

Putting x = 0 in f(x) determine the range for the value x = 3

[tex]f(x)=-8x+13[/tex]

[tex]f(3)=-8(3)+13=-24+13=11[/tex]

Therefore, the complete set of domain (x) and range values (y) is given by:

x                   y

-2                39

0                 13

3                  11

Answer:

9.433981132

Step-by-step explanation:

To learn how to find the distance between two points by using the distance formula, which is an application of the Pythagorean theorem. We can rewrite the Pythagorean theorem as d=√((x_2-x_1)²+(y_2-y_1)²) to find the distance between any two points, and I used my calculator to do so.

Answer:

a = 21

Step-by-step explanation:

Given

[tex]\frac{a+19}{5}[/tex] = 8 ( multiply both sides by 5 to clear the fraction )

a + 19 = 40 ( subtract 19 from both sides )

a = 21

Answer:

8x^9

Step-by-step explanation:

(2x^3)^3 =

First, to raise a product to an exponent, raise eve3ry factor to the exponent.

Second, to raise a power to a power, multiply powers.

= 2^3 * (x^3)^3

= 8 * x^9

= 8x^9

Answer:

answer must be $880.

48 papperoni pizza =48 * 15= 720

16 cheese pizza =16 * 10= 160

Total sell =$880

He make $880 for selling pizzas yesterday.

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

Tim sells two types of pizza. He charges $10 for a cheese pizza and $15 for a pepperoni pizza.

And, Yesterday he sold 64 pizzas in all. For every cheese pizza, he sells 3 pepperoni pizzas.

Now,

Since, For every cheese pizza, he sells 3 pepperoni pizzas.

Hence, Let number of cheese pizza = x

Then, Number of pepperoni pizzas = 3x

Since, Yesterday he sold 64 pizzas in all.

So, We get;

⇒ x + 3x = 64

⇒ 4x = 64

⇒ x = 16

Thus, Number of cheese pizza = x = 16

Then, Number of pepperoni pizzas = 3x

                                                      = 3 × 16

                                                      = 48

So, The cost of 16 cheese pizza and 48 pepperoni pizza are;

⇒ Total cost = 16 × $10 + 48 × $15

⇒ Total cost = $160 + $720

⇒ Total cost = $880

Thus, He make $880 for selling pizzas yesterday.

Answer:

g=18

Step-by-step explanation:

[tex]g-16=2\\g-16+16=2+16\\g=18[/tex]

Hope this helps u.

Please hit the crown :D

Answer:

g = 18

General Formulas and Concepts:

Pre-Algebra

Step-by-step explanation:

Step 1: Define

g - 16 = 2

Step 2: Solve for g

Step 3: Check

Plug in g into the original equation to verify it's a solution.

Here we see that 2 does indeed equal 2.

∴ g = 18 is a solution of the equation.

Answer:

AE:[tex]\sqrt{15300}[/tex]

DE:150

PABCDE: 720

Step-by-step explanation:

We can find AE by the pythagorean theorem, [tex]a^{2}+b^{2}=c^{2}[/tex]

AE is the hypotenuse so AE=c, and the leg of the triangle would be 150-30=120

[tex]50^{2}+120^{2}=c^{2}[/tex]

c^2=2500+14400

AE=130

We can use the pythagorean theorem again to find DE.

The base would equal 140-50=90 and the height would equal 120

[tex]90^{2} +120^{2} =DE^{2}[/tex]

DE^2=22500

DE=150

The perimeter would be 150+140+150+130+150=720

Answer:

$6.60

Step-by-step explanation:

Answer:

$6.6

Step-by-step explanation:

We add the amount he paid,

($87.21 + $5.64) - $15.00 + 55.25

We will get ,

$92.85 - $15.00 + $55.25

Then,

$77.85 + $55.25

We will get,

$133.10, the subtract the $133.10 from his original balance and get

$126.50 - $133.10 = $-6.6

He will need to deposit $6.6 to get his account to $0 balance

Answer:

The equation of the line is:

[tex]y=-x+5[/tex]

Step-by-step explanation:

Given the points

Finding the slope between the points

[tex]\left(x_1,\:y_1\right)=\left(-3,\:8\right),\:\left(x_2,\:y_2\right)=\left(4,\:1\right)[/tex]

[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]m=\frac{1-8}{4-\left(-3\right)}[/tex]

[tex]m=-1[/tex]

Using the point-slope form of the line equation

[tex]y-y_1=m\left(x-x_1\right)[/tex]

where m is the slope

substituting the values m = -1 and the point (-3, 8)

[tex]y-y_1=m\left(x-x_1\right)[/tex]

[tex]y-8=-1\cdot \left(x-\left(-3\right)\right)[/tex]

[tex]y-8=-\left(x+3\right)[/tex]

Add 8 to both sides

[tex]y-8+8=-\left(x+3\right)+8[/tex]

[tex]y=-x+5[/tex]

Therefore, the equation of the line is:

[tex]y=-x+5[/tex]
