Answer: ion know i'm guessing 4

Step-by-step explanation: because it shows 8 at the top, so since it's full and it's 4,000 then that'll basically make 8 the 4000, so since 4 is half of 8 then we prolly have our answer right there

Answer: It would be 20

Step-by-step explanation: The formula for height would be h= v/pi r squared, just plug in the numbers

Answer:

The number 0 is the smallest non-negative integer. The natural number following 0 is 1 and no natural number precedes 0. The number 0 may or may not be considered a natural number, but it is an integer, and hence a rational number and a real number (as well as an algebraic number and a complex number).

Cardinal: 0, zero, "oh" (/oʊ/), nought, naught, nil

Binary: 0

               2

Hexadecimal: 0

Answer:

That old mans change in height is -1 1/4 over 5 years.

Step-by-step explanation:

Answer:

-5/4 cm would be the answer.

Step-by-step explanation

This is the answer because -1/4 cm multiplied by 5 years would equal -5/4 cm.

Answer:

60 degrees

Step-by-step explanation:

Answer:

ADEF

Step-by-step explanation:

Four of the six equations that Justin wrote are correct which are Trigonometric functions as sin 60° =√3/2, cos 60° = 1/2, tan 60° = √3, and cot 60° = 1 /√3.

Trigonometric functions are defined as the functions which show the relationship between the angle and sides of a right-angled triangle.

Given that ΔABC

∠A = 60° and ∠B = 90° which is given in the figure

⇒ sin 60° = perpendiculer /hypotenuse

⇒ √3/2 = BC/10

⇒ BC = √3/2 × 10

⇒ BC = 5√3

⇒ tan 60° = perpendiculer /base

⇒ √3 =  5√3/AB

⇒ AB = 5√3/√3

⇒ AB = 5

⇒ sin 60° = 5√3/10 = √3/2

⇒ cos 60° = base / hypotenuse

⇒ cos 60° = 5/10 = 1/2

⇒ tan 60° = perpendiculer /base

⇒ tan 60° = 5√3/5 = √3

⇒ cot 60° = 1 /√3

Hence, four of the six equations that Justin wrote are correct which are Trigonometric functions as sin 60° =√3/2, cos 60° = 1/2, tan 60° = √3, and cot 60° = 1 /√3.

Answer:

Line 2 ║ Line 3

Step-by-step explanation:

y = mx + b

~~~~~~~~~~

Line 1: y = - 7x + 6

Line 2: x + (1/3)y = - 6 ⇔ y = - 3x - 18

Line 3: y = - 3x - 8

Line 4: y + 7 = (-1/7)(x + 4) ⇔ y = [tex]- \frac{1}{7}[/tex] x - [tex]\frac{43}{7}[/tex]

[tex]m_{line2}[/tex] = [tex]m_{line3}[/tex]  ⇒  Line 2 ║ Line 3

Answer:

$9.99 + $1.29n ≤ $50

Step-by-step explanation:

Given that:

Worth of gift card = $50

Cost of album purchased = $9.99

Cost per song to purchase = $1.29

Number of songs to purchase = n

Inequality to model the situation :

Cost of album + cost per song * (Number of songs) ≤ worth of gift card

$9.99 + ($1.29 * n) ≤ $50

$9.99 + $1.29n ≤ $50

Answer:

x is also 63 degrees this is because vertical angles are congruent or like equal in measure

Step-by-step explanation:

HOPE THIS HELPEDDDD

Answer:

63 degrees

Step-by-step explanation:

Since m is parallel to n, the angle that is marked 63 degrees and x are alternate interior angles. The alternate interior angle theorem states that alternate interior angles are congruent when a line cuts through two parallel lines. So, since m and n are parallel, these are congruent angles, making x also 63 degrees.

Answer:

$111.18

Step-by-step explanation:

Dinner is $88.24

Tax is (.05)$88.24 = $4.41

20% after tax added (.20)92.65 = $18.53

total dinner cost is $111.18

Answer:

$57.8

Step-by-step explanation:

Horseshoe ranch charges $12.95 ranch entrance fee

$14.95 is paid per hour to rent the horse

Therefore since Mary is going to rent the horse for 3 hours then the total amount she will spend can be calculated as follows

= $12.95 + $14.95×3

= $12.95 + $44.85

=$57.8

Product hints at multiplication so -5n is AT LEAST meaning that it is at or greater than 35....

-5n ≥ 35

Answer:

-5x≥35

Step-by-step explanation:

The word "product" means to multiply so I know that -5 times a number x is at least 35. The phrase "at least" means greater than or equal to so I know its a ≥ sign.

Answer:

9

Step-by-step explanation:

Class width = 29 - 20 = 9

Answer:

the number is 11

Step-by-step explanation:

"Diminished" is another word for subtraction, so our equation is : 9x - 4 = 95

Add 4 on each side: 9x = 99

Divide each side by 9: x = 11

I hope this helped, please mark Brainliest, thank you!

Answer:

Step-by-step explanation:

Let a number be X

So

Nine times a number, diminished by 4, is 95

9x-4=95

9x=95+4

9x=99

X=99/9

X=11

So the number is 11

Answer:

[tex]Base = 57[/tex]

Step-by-step explanation:

Given

[tex]Length = 2x + 4[/tex]

[tex]Base = 3x[/tex]

[tex]Perimeter = 141[/tex]

Required

Determine the length of the base

The perimeter of an isosceles triangle is:

[tex]Perimeter = 2*Length + Base[/tex]

[tex]141 = 2 (2x + 4) + 3x[/tex]

[tex]141 = 4x + 8 + 3x[/tex]

Collect Like Terms

[tex]4x + 3x = 141 - 8[/tex]

[tex]7x = 133[/tex]

Divide both sides by 7

[tex]x = 19[/tex]

To get the base, we substitute 19 for x in [tex]Base = 3x[/tex]

[tex]Base = 3 * 19[/tex]

[tex]Base = 57[/tex]

Answer:

Yes , Avery is correct

Step-by-step explanation:

To check if Avery is correct, we need to know the exact value obtained in each of their goals

For Avery’s team;

3/5 * 450 = $270

For Nolan’s team

5/9 * 450 = $250

Since $270 is greater than $250, we can see that Avery’s team collected more money

Given :

A local business charges $20 to set up their sweatshirt printing machine with the design and $9.75 in materials per sweatshirt to print.

To Find :

Write an equation for the average cost A(x) of printing x sweatshirts through this company.

Solution :

Let, number of sweatshirts sold are x.

So, average cost A(x) of printing is given by :

A(x) = 9.75x + 20

Therefore, average cost per sweatshirts are A(x) = 9.75x + 20 .

Hence, this is the required solution.
