A size 8 kid’s shoe measures 9 2/3 inches. If 5 size 8 shoes are lined end to end, then how many inches will they cover?

Answer:

it takes José an 1.18181818 hours

Step-by-step explanation:

since d is miles you replace the d in the equation with 100

so: 100=55t

divide both sides by 55

1.18181818=t

Answer:

A. 1/9

Step-by-step explanation:

In order to find probability, you need to add up the total number of cards Dana has.

14 + 10 + 8 + 4 = 36

Then set up a fraction representing probability.

4 hockey cards

---------------------

36 total cards

Simplify

1

---

9

This means that Dana has a 1 out of 9 chance of getting a hockey card.

The numbers which should be placed in the boxes from left to right, when Juanita factor the expression, is 6 and 3 respectively.

The factor of a polynomial is the terms in linear form, which are, when multiplied together, give the original polynomial equation as a result.

Juanita begins to factor an expression as shown.

[tex]x^2+ 3x-18=(x+ \;\;)(x-\;\;)[/tex]

To find the value of blank, we have to factor the left-hand side expression using the split the middle term method as,

[tex]x^2+ 3x-18\\x^2+ 6x-3x-18\\x(x+6)-3(x+6)\\(x+6)(x-3)[/tex]

Lucas's car dealerships' expected revenue over the next 3 days is $6800

The expected revenue is calculated using the following formula of expected value

[tex]E(x) = \sum x * P(x)[/tex]

The data elements on the table are represented as:

Days        Revenue

0              3000

1               1800

2              1300

3               800

So, we have:

E(x) = 0 * 3000 + 1 * 1800 + 2 * 1300 + 3 * 800

Evaluate the sum of the products

E(x) = 6800

Hence, Lucas's expected revenue is $6800

Formula

Solving

The quadratic equation which matches given solution is x² + 3x + 3 = 0. Then the correct option is C.

It is a polynomial that is equal to zero. Polynomial of variable power 2, 1, and 0 terms are there. Any equation having one term in which the power of the variable is a maximum of 2 then it is called a quadratic equation.

We know that the formula

[tex]\rm x = \dfrac{-b\pm \sqrt{b^2-4ac}}{2a}[/tex]

The solutions are given below.

[tex]\rm x = \dfrac{-3 \pm \sqrt3 \iota }{2}[/tex]

Then

1)  2x² + 6x + 9 = 0, the zeroes of the equation will be

[tex]\rm x = \dfrac{-6\pm 6\iota}{4}\\\\x = \dfrac{-3\pm 3 \iota}{2}[/tex]

2)  x² + 3x + 12 = 0, the zeroes of the equation will be

[tex]\rm x = \dfrac{-3\pm \sqrt{39}\iota}{2}[/tex]

3)  x² + 3x + 3 = 0, the zeroes of the equation will be

[tex]\rm x = \dfrac{-3\pm \sqrt3\iota}{2}[/tex]

4)  2x² + 6x + 3 = 0, the zeroes of the equation will be

Answer:

Find the cube's volume first (because it's the simplest figure) by using the formula;

(Formula for vol. of cube)

V = [tex]s^{3}[/tex]

Where 's' stands for one side of the cube raised to the power of three.

or

V = w · l · h

Where 'w' stands for the width, 'l' stands for the length, and 'h' stands for the height.

Plug in the values you know since they literally give it to you (I'll be using the formula [tex]s^{3}[/tex]);

V = [tex]s^{3}[/tex]

V = 3^3 → (The symbol ' ^ ' means to the power of.)

V = 27, is the volume of the cube.

Now we find the volume of the pyramid using the formula;

(Formula for vol. of pyramid)

V = (l · w · h) · 1/3

Where 'l' means the length, 'w' the width, and 'h' the height whereas the 1/3 is just dividing the product of those three by 3.

Plug in the values you know using both the lengths from the cube and pyramid.

Length = 3

Width = 3

Height = 3(we won't use)

Height = 4

Use these to figure out the volume for the pyramid.

V = (l · w · h) · 1/3

V = (3 · 3 · 4) · 1/3

V = 36 · 1/3

V = 36/3

V = 12, is the volume of the pyramid.

Add your volumes:-

27(cube vol.) + 12(pyramid vol.)

= 39 is the volume for this whole solid, your answer is D.

Answer:

4

Step-by-step explanation:

Here we know that T is the midpoint of SU.

Therefore, we know ST and TU are equal.

Setting their values equal, we get:
x+3 = 4x

Then we isolate x by subracting x from both sides:

3=3x

Finally we divide by 3:

1=x

Now we can solve for TU:

4x= 4(1) = 4

Answer:

500

Step-by-step explanation:

let's say charlie sends x messages per month

he spends $50 + 0.05 for each x (message), which comes out to less than or equal to $75.

as an equation, this is

50 + 0.05 x ≤ 75

subtract both sides by 50 to isolate the variable and its coefficient

0.05 x ≤ 25

multiply both sides by 1/0.05 to isolate x

x ≤ 500

the maximum is therefore x = 500 messages

Answer: 2x+5y=50

Step-by-step explanation:

x=number of 2-ounce weights

y=number of 5-ounce weights

Because of this you will write the total weight (50) is equal to __. On the other end you will multiply the possible number of 2-ounce weights to 2 because this will give you the weight for the 2 ounce. The same is done for the 5-ounce weights. Once you combine both of them you would get the total weight. Which is why 2x+5y=50 is the answer.

Answer:

Domain:  { x ∈ R | x ≠ -2, 3 }

Step-by-step explanation:

[tex]f(x)=\dfrac{(x+2)(x-1)}{(x-3)(x+2)}[/tex]

The domain (x-values) of a rational function is all real numbers of x with the exception of those for which the denominator is 0.   Therefore, to find the values of x that need to be excluded from the domain, equate the denominator to zero and solve for x.

The denominator for the given function is [tex](x - 3)(x + 2)[/tex]

[tex]\implies (x - 3)(x + 2)=0[/tex]

[tex]\implies (x - 3)=0\implies x=3[/tex]

[tex]\implies (x + 2)=0 \implies x=-2[/tex]

There will be a hole at x = -2 and an asymptote at x = 3.

So the values of x that need to be excluded from the domain are:

x = 3 and x = -2

Therefore, the domain of the given rational function is:  { x ∈ R | x ≠ -2, 3 }

Answer:

2.5h + 4 = 12 is your equation

2.5h = 12 - 4

2.5h = 8

h = 8 / 2.5

h = 3.2 hrs

Step-by-step explanation:

Answer:

2.5h + 4 = 12 is your equation

2.5h = 12 - 4

2.5h = 8

h = 8 / 2.5

h = 3.2 hrs

The composite figure includes a rectangle and trapezoid

The area of the composite figure is 810.5cm².

From the complete question, we have the following parameters:

Shapes: Rectangle and trapezoid

The area of the rectangle is:

Area = Length × Width

So, we have:

Area = 15 × 23

Area  = 345cm²

The area of the trapezium

Area = 0.5 × (a + b) ×h

So, we have:

Area = 0.5 × (15 + 34) × 19

Area = 0.5 × 49 × 19

Area = 465.5cm²

Add both areas to calculate the area of the composite figure

Total area = 345cm² + 465.5cm²

Total area  = 810.5cm²

Hence, the area of the composite figure is 810.5cm².
