857 runners entered a race. 354 more entered before
the race started. How many runners are in the race?

Answer: the answer is 73.5 but it is not here so I think 89 is the

Step-by-step explanation:

Answer:

The answer is 149

Step-by-step explanation:

So 2 oranges added up is 56 which is basically

x+x=56

2x=56

56/2=28

Each orange is worth 28

The 2 triangles multiplied are 81 which is

x*x=81

x^2=81

√81=9

Each watermelon Is worth 9

The 3 stars added up are

x+x+x=15

3x=15

15/3=5

Each star is worth 5

So the final equation if you plug in what we know

9+28*5

So orders of operations, (Parenthesis, exponents, etc.)

So multiplication is first

28*5=140

And add

140+9=149

So final answer 149

Answer:

y= 8/3

Step-by-step explanation:

Answer:

It's C (0,3)

Step-by-step explanation:

Answer:

(3,0) D

Step-by-step explanation:

x intercept is when the line meets x axis. It meets it at 3

In (x,y) form it is (3,0)

Answer: x = 2 and y = 5

Step-by-step explanation:

y = 2x + 1

3x + y = 11

Substitute

3x + (2x + 1) = 11

5x + 1 = 11

Subtract both sides by 1

5x = 10

Divide both sides by 5

x = 2

y = 2x + 1

Substitute

y = 2 (2) + 1

y = 4 + 1

y = 5

4 chapters every hour

Answer: Length ≥ 6 feet

Step-by-step explanation:

The area of a rectangle= length × width

In this case, the width is 4 feet and the area of the stage must be at most 24 square feet.

The inequality that describes the possible lengths (in feet) of the stage would be:

Length × Width ≥ 24

Length × 4 ≥ 24

Length ≥ 24/4

Length ≥ 6

Therefore, the length must be at most 6 feet.

Answer: She has 21.63 more euros than pounds and has 1.23 times more euros than pounds.

Step-by-step explanation:

She has US$300, and she will withdraw half of it on pounds, and half of it in euros.

(half of US$300 is US$150)

We know that:

1 pound = US$1.6

(1 pound/US$1.6) = 1

Then US$150 = US$150*(1 pound/US$1.6) = (150/1.6) pounds = 93.75 pounds.

And we also know that:

1 euro = US$ 1.3

then:

(1 euro/US$ 1.3) = 1

This means that:

US$150 = US$150*(1 euro/US$ 1.3) = (150/1.3) euros = 115.38 euros.

This means that:

115.38 - 93.75 = 21.63

This means that she has 21.63 more euros than pounds.

and:

115.38/93.75 = 1.23

She has 1.23 times more euros than pounds.

Answer:

[tex]V=2078.16\ cm^3[/tex]

Step-by-step explanation:

A rectangular sheet of dimensions 33 cm x 24 cm is rolled into a cylinder so that the smaller side becomes the height of the cylinder.

h = 24 cm

and the circumference of the cylinder, C = 33 cm

[tex]2\pi r=33\\\\r=\dfrac{33}{2\pi}\\\\r=5.25\ cm[/tex]

We need to find the volume of the cylinder so formed. The formula for the cylinder is given by :

[tex]V=\pi r^2h\\\\=\pi \times 5.25^2\times 24\\\\=2078.16\ cm^3[/tex]

So, the volume of the cylinder so formed is [tex]2078.16\ cm^3[/tex].

Answer:

d

Step-by-step explanation:

Answer:

option D

Step-by-step explanation:

[tex]\sqrt{10x+50}=x+5\\\\(\sqrt{10x+50})^2=(x+5)^2\\\\10x+50=x^2+10x+25\\\\0=x^2+10x-10x+25-50\\\\0=x^2-25\\\\0=(x-5)(x+5)\\\\x=5\\\\x=-5[/tex]

now trying for the original equation

[tex]\sqrt{10(5)+50}=5+5\\\\\sqrt{50+50}=10\\\\\sqrt{100}=10\\\\10=10[/tex]

and

[tex]\sqrt{10(-5)+50}=-5+5\\\\\sqrt{-50+50}=0\\\\\sqrt{0}=0\\\\0=0[/tex]

so it's option D

Answer:

x=9

Step-by-step explanation:

In a parallelogram, opposite angles are equal.

So that means

2(3x - 4) = x + 37

6x - 8 = x + 37

5x = 45

x = 9

Answer:

x+37=2(3x-4) opposite angle of the parallelogram are equal

x+37=6x-8

37+8=6x-x

45=5x

x=9

Using translation concepts, it is found that the equation is given by:

[tex]y = -3\sqrt[3]{x} - 8[/tex]

A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction in it's definition.

The parent cube root function is given by:

[tex]y = \sqrt[3]{x}[/tex]

It was reflected across the x-axis, that is, multiplied by -1, hence:

[tex]y = -\sqrt[3]{x}[/tex]

It was vertically stretched by a factor of 3, hence:

[tex]y = -3\sqrt[3]{x}[/tex]

Then, it was translated 8 units down, hence:

[tex]y = -3\sqrt[3]{x} - 8[/tex]

Answer:

[tex]2.9 cm^2[/tex]

Step-by-step explanation:

Given,

Angle of sector = 30°

Radius of circle, r = 8 cm

Area of the shaded region, A =?

The diagram is attached below.

Now,

Area of shaded region = Area of sector - Area of triangle

Area of triangle = [tex]\frac{1}{2}\times base \times height[/tex]

We know that,

[tex]\sin \theta = \dfrac{P}{H}[/tex]

[tex]\sin 30^\circ= \dfrac{P}{8}[/tex]

[tex]P = \dfrac{8}{2}[/tex]

[tex]P = 4\ cm[/tex]

And

[tex]\cos \theta =\dfrac{B}{H}[/tex]

[tex]\cos 30^\circ = \dfrac{B}{8}[/tex]

[tex]B = \dfrac{8\times \sqrt{3}}{2}[/tex]

[tex]B = 4\sqrt 3[/tex]

Area of sector = [tex]\dfrac{\theta}{360^\circ}\times \pi r^2[/tex]

Area of sector =  [tex]\dfrac{30^\circ}{360^\circ}\times \pi \times 8^2[/tex]

                        = 16.75 cm^2

Area of triangle = [tex]\dfrac{1}{2} \times 4\sqrt 3 \times 4[/tex]

                          = 13.85 cm^2

Area of shaded region = 16.75 - 13.85

                                      = [tex]2.9 cm^2[/tex]

Answer:

x = -2

Step-by-step explanation:

20(x+9)=140

divide both sides by 20

x + 9 = 7

move the 9

x = 7 - 9

x = -2

Answer:

x = -2

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS

Equality Properties

Step-by-step explanation:

Step 1: Define

20(x + 9) = 140

Step 2: Solve for x

Step 3: Check

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

Here we see that 140 does indeed equal 140.

∴ x = -2 is the solution to the equation.

Answer:

384 but see below.

Step-by-step explanation:

Remark

A_n = 3*2^(n - 1) I will assume that's what you mean. I'll give the answer for A_n = 3*2^n - 1 as well.

Solution

n = 8

A_n = 3 *2^(8 - 1)

A_8 = 3*2^7

A_8 = 3* 128

A_8 = 384

If you mean A_n = 3*2^n - 1

Then you would get

A_n =3 * 2^8 - 1

A_8 = 3 * 256 - 1

A_8 = 768 - 1

A_8 = 767
