Answer:

C = 8.8 m

Step-by-step explanation:

Cos(25) = CB/AB = 8m / c, then c = 8m / cos(25) = 8.8 m

Answer:

4p√7

Step-by-step explanation:

Answer:

√160

Step-by-step explanation:

For y-intercept, we use y = mx + c. Comparing both, y = mx +c & y = 3x + 12

y intercept = c = 12

Point is (0, 12)

For x intercept, we use y = m(x - d). We have

y = 3x + 12 → y = 3(x - (-4))

Compare both, x intercept = d = - 4

Point is (-4, 0)

Using distance formula,

Distance = √(0-12)² + (-4-0)² = √12²+4²

Distance = √144+16 = √160

Answer:

152

Step-by-step explanation:

Let x be the number of children tickets sold

2x+x=228

combine like terms

3x=228

x=76

adult tickets is two times the amount of x

2x=152

Answer:

200r

Step-by-step explanation:

All you have to do is multiply the 10 and 20 to get 200 and then put the r after the 20, so it would look like this 200r

[tex]\Huge\boxed{x=8}\\\\\Huge\boxed{y=138}[/tex]

Step-by-step explanation:

Hello There!

Knowing that the sum of the angles in a triangle is 180

we can use this equation to solve for x

180 = 90 + 5x + 2 + 6x

Step 1 combine like terms

90 + 2 = 92

5x  + 6x = 11x

now we have

180 = 11x + 92

step 2 subtract 92 from each side

180 - 92 = 88

92 - 92 cancels out

now we have

88 = 11x

step 3 divide each side by 11

11x/11 = x

88/11 = 8

we're left with x = 8

Now we plug in 8 into x for 5x + 2 so we can solve for y

5*8=40

40+2 = 42

Now we can solve for y

the angle measured 42 degrees and the angle labeled y are supplementary angles meaning that the sum of the two angles is 180

so to find y we subtract the given angle (42) from 180

180 - 42 =138 so we can conclude that y = 138

Notes: the little square represents a right angle which has a measure 90 degrees so thats where the 90 came from .

Answer:

35.1 megabytes downloaded (rounded)

Step-by-step explanation:

12.9% = 0.129

272 x 0.129 = 35.088

35.088 rounded to the nearest tenth would be 35.1

Answer:

equation: y=-5/9(x)+8/9 slope: y=-5/9(x)

Step-by-step explanation:

9y=8-5x

y=(8/9)-(5/9)x

y=-5/9(x)+8/9

Answer:

x=3

y=1

Step-by-step explanation:

-2x - 7y = -13

3x + 6y = 15

3(-2x - 7y = -13) = -6x - 21y = -39

2(3x + 6y = 15) = 6x + 12y = 30

-6x - 21y = -39

----------------------  The -6x and 6x cancel out, 12 - 21 is equal to 9, 30 - 39 = -9

6x + 12y = 30

Therefore, you can say that -9y = -9 so y = 1

FInally, plug that back into either one of the original equations:

3x + 6(1) =15

3x = 9

x = 3

Answer:

AC=18

Step-by-step explanation:

To find AC, use the Pythagorean Theorem.  Since the longest side (hypotenuse) is known, instead of a²+b²=c², the equation will be c²-a²=b².  12²-8²=b²

144-64=b²

80=b²

√80=√b²

8.94427191=b

That is for one of the two right triangles that make up the tent.  Since there are 2 triangles, 8.94427191 only equals BC or AB.  So, multiply 8.94427191×2=17.88854382 to find the length of AC.

AC= 18

Costo total= $1.120.000

Step-by-step explanation:

Dada la siguiente información:

Se necesita instalar el piso de una habitacion de forma rectangular cuyas dimensiones son 7 m por 8 m.

Costo por m2=  $20.000

Primero debemos calcular el total de metros cuadrados de la habitación:

Totalm2= 7*8= 56m2

Ahora el costo total:

Costo total= 56*20.000

Costo total= $1.120.000
