Answer:

10.3

Step-by-step explanation:

Use the pythagorean theorem.

3.9^2 + x^2 = 11^2

x^2 = 105.79

x = 10.3

Answer:

x = 9/2, y = -5/2

Step-by-step explanation:

5x + y = 20

10x - 2y = 50

There's multiple ways to do this, but I will solve using substitution.

Isolate variable y on the first equation.

5x + y = 20

y = 20 - 5x

Substitute the value of y for 20 - 5x in the second equation.

10x - 2(20 - 5x) = 50

Use distributive property:

10x - 40 + 10x = 50

Combine like terms:

20x - 40 = 50

20x = 90

x = 90/20

x = 9/2

Substitute x for 9/2 and solve for y:

y = 20 - 5(9/2)

y = 20 - 45/2

y = 40/2 - 45/2

y = -5/2

Answer:

x =9/2, y = -5/2

Step-by-step explanation:

5(9/2) + -(5/2)= 20

45/2 + -5/2 = 20

40/2 = 20

10(9/2) - 2(-5/2) = 50

90/2 + 10/2 = 50

45 + 5 = 50

Answer:

Stanley needs 31 feet and 2 inches of fencing.

Step-by-step explanation:

In order to answer this problem, you need to find the perimeter of the dog run.

Since: [tex]P=2(l+w)[/tex]

and [tex]l=149[/tex] inches & [tex]w=56[/tex] inches

Plug in what we know :

[tex]P=2(149+56)[/tex]

and solve:

[tex]P=410[/tex] inches

The dog run has a perimeter of 410 inches.

However, now we need to subtract 36 inches since the gate doesn't need fencing.

[tex]410-36=374[/tex] inches.

The dog run needs 374 inches of fencing.

In order to find out how many feet of fencing that is, divide it by 12.

[tex]\frac{374}{12}[/tex] = 31.16666667 OR [tex]31\frac{2}{12}[/tex], meaning 31 feet and 2 inches.

Answer:

31 feet and 2 inches of fencing :))<3

Answer:

C) y=4x-5

Step-by-step explanation:

Hey there!

“4y + 3x”

If x = 5 and y = -3, then substitute it into the equation

4(-3) + 3(5)

4(-3) = -12

-12 + 3(5)

3(5) = 15

-12 + 15

= 3

Step-by-step explanation:

Breakeven quantity are the number of  units produced and sold at which net income is zero

Breakeven quantity = fixed cost / price – variable cost per unit

Fixed costs are costs that do not vary with output. e,g, rent, mortgage payments

If production is zero or if production is a million, Mortgage payments do not change - it remains the same no matter the level of output.  

Hourly wage costs and payments for production inputs are variable costs

Variable costs are costs that vary with production

fixed cost = $2450

Variable cost = $75

price = $145

(2450) / (145 - 75) = 35

Q2:

Answer=170.8 sq.ft

Answer:

The LCM of 9, 12, and 24, is 72.  

Step-by-step explanation:

To find the answer you must figure out the factors of each number, and see which factor has the same number.  

Factors of 9:         Factors of 12:        Factors of 24:

       9                            12                          24

       18                          24                          48

       27                          36                         72

       36                          48

       45                          60

       54                          72

       63

       72

When we look at all these factors, none of them have the same number except 72.  Since all of these factors have 72 in them, this is the LCM of 9, 12, and 24.

área del parque

A=Pi . R^2

A=Pi (700m^2)

A=3.1416 x 490000m^2

A= 1539380.4 m ^2

área de la fuente

a= Pi. r^2

a=Pi (5cm^2)

a=3.1416 x 25cm^2

a= 78.54 cm^2

Luego lo que hacemos que al area grande le restamos la pequeña.

pero antes que nada convertiremos los metros a centimetros.

A= 1539380.4 m^2

1539380.4 m^2 (100cm/1m)

eliminaras los metros y te quedara asi

1539380.4  ( 100 cm/ 1)

153,938,040 cm^2

luego restamos A-a

153,938,040 cm^2 -  78.54cm^2

R/ el area de la zona de paseo es de 153937961.5 cm^2 !!

Answer:

its c

Step-by-step explanation:

Answer:

C

Step-by-step explanation:

First of all we can simplify the the first therm because a property of power says that we can simplify a power of power by multiply the exponents

a^4b^8c^2

For the same property 2c^5 becomes 8c^15

now we have

(a^4b^8c^2)(6a^3b)(8c^15)/4a^6b^12c^3

if we simplify the numbers we can obtain

(a^4b^8c^2)(6a^3b)(2c^15)/a^6b^12c^3

If we simplify the parameters we can obtain

12ac^14/b^3

Answer: I’m pretty sure the answer is d

Step-by-step explanation:

x=2 or x=-8 are the answers to the questio.

A denotes the angle that faces side a, and B denotes the angle that faces side b. To solve for b, we obtain: b = a / sin(B) (A)

A geometric shape known as an angle is created when two rays or line segments come together to form its vertex. The two rays or line segments are known as the angle's sides. Angles are used to describe the orientation, direction, and position of lines and forms in geometry. They are commonly measured in degrees or radians. The magnitude of an angle can range from 0 degrees (representing no rotation) to 360 degrees depending on how much the two sides or rays are rotating (corresponding to a full rotation).

given

We may utilise the Law of Cosines to determine the potential values of U:

A2 + B2 - 2ab cos = c2 (C)

where a and b are the lengths of the other two sides, and c is the length of the side that faces angle C. We'll write c for the length of side SU and a for the length of side ST.

Based on the facts provided, we can:

a=630 inches

b = u (unknown) (unknown)

C = ∠T = 7°

We can apply the Law of Sines to determine the length of b:

B = a / sin = b / sin(B) (A)

where A denotes the angle that faces side a, and B denotes the angle that faces side b. To solve for b, we obtain: b = a / sin(B) (A) .

Explanation:

Recall that the general point-slope form is [tex]y - y_1 = m(x - x_1)[/tex] where m is the slope and [tex](x_1, y_1)[/tex] is the point the line goes through. We see that the 2 and the m match up, so m = 2 is the slope.

Side note: We can rewrite that given equation into y - (-5) = 2(x - (-1)) to see that the line goes through the point (-1, -5)
