What is the area of the triangle shown below

Answer:

here the value of X should be 8 to make this proportion true

3/8=15/40

by cross multiplying

15*8=40*3

120=120

therefore the option C is correct

Step-by-step explanation:

Datos;

una locomotora

recorre 5 horas

a una velocidad de 82 km/h

Se asume que la locomotora lleva un movimiento rectilíneo uniforme.

Su recorrido esta descrito por la siguiente ecuación de posición;

x = x₀+ v · t

x-x₀ = d = v · t

siendo;

d = distancia recorrida

v = 82 km/h

t = 5 horas

Sustituir:

d = (82)(5)

d = 410 km

82km/h * 5h= 410km

La locomotora recorrerá 410km

Answer:

52

Step-by-step explanation:

The missing sides is equal to the opposite side

So add all the sides up

The answer is the D ( the last one)

Answer:

3 5/12 cups of flour are needed

Step-by-step explanation:

The flour-sugar total is 3 2/3 cups, of which 1/4 cup is sugar.  So, to find the amount of flour used, we subtract 1/4 cup (sugar) from the total (3 2/3 cups):

 11       1

----- - ----              where 11/3 is the improper fraction form of 3 2/3

   3      4

The LCD is 12.  Rewriting this subtraction using the LCD, we get:

44     3

---- - ----- = 41/12 (cups) = 3 5/12 cups

12     12

3 5/12 cups of flour are needed

Answer:

112

Step-by-step explanation:

Answer:

We have

Angle ORQ

we use the Thales theory

From the formulae

A²+B²=C²

consider

A=OR

B=RQ

C=OQ

so

48²+64²=C²

2304+4096=C²

6400=C²

(6400)¹/²=(C²)¹/²

80=C

But

C=OQ

《OQ=80

Answer:

95 ≤ 8 < 1/7n

Step-by-step explanation:

95 ≤ 8 < 1/7n

no more = less than or equal to

product of a number n and 1/7 = 1/7•n = 1/7n

Answer:

Between 4 and 5

Step-by-step explanation:

The closest square numbers are 16 and 25, so it’s in between 4 and 5

Step-by-step explanation:

11/12-?=2/3

11/12-2/3=?

11-8/12=?

3/12

=1/4

Answer:

? = 1/4

Step-by-step explanation:

11 / 12 - ? = 2 / 3

- ? = 2/3 - 11/12

- ? = - 1/4

? = 1/4

Answer

Step-by-step explanation:

8^-5/8^-2

=8^5-(-2)

=8^5+2

=8^7

=2097152

Note in division if the base the base are same then u can subtract their exponent but in multiplication bases are same u should add their exponent.

Answer:

Step-by-step explanation:

16

Step-by-step explanation:

10x+2=9x+18

-2 -2

10x=9x+16

-9x -9x

x=16

Hope this helps! :)

Answer:

x = 16°

Step-by-step explanation:

(10x + 2)° = (9x + 18)°

10x + 2 = 9x + 18

10x + 2 - 2 = 9x + 18 - 2

10x = 9x + 16

10x - 9x = 9x - 9x + 16

x = 16°

bearing in mind that cos(θ) < 0, is just another way to say that cos(θ) is negative, and sin(θ) > 0, is just another way to say that sin(θ) is positive.

Answer:

4?

Step-by-step explanation:

So, at from x 0 to x 2, y goes up 4

Answer:

2

Step-by-step explanation:

The rate of change is defined by [tex]\frac{Rise}{Run}[/tex] , [tex]\frac{y_{2} - y_{1} }{x_{2}-x_{1}}[/tex]. or [tex]\frac{Delta y}{Delta x}[/tex].

For your question, the points are (0,4) and (2,8).

Plugging these points into the formula:

[tex]\frac{8-4}{2-8}[/tex]

After calculations, you would end up with [tex]\frac{4}{2}[/tex] or 2.

Answer:

No solution

Step-by-step explanation:

2(n-1)+4n=2(3n-1)

2n-2+4n=6n-2

6n-2=6n-2

No solution

Answer:

0

Step-by-step explanation:

2(n-1)+4n=2(3n-1)

2n - 2 + 4n = 6n - 2

2n + 4n - 2 = 6n - 2

6n - 2 = 6n - 2

0 = 0

Answer:

$557.52

Step-by-step explanation:

Solve for marked up price:

892.03 × 1.25

1115.0375

Solve for discounted price:

1115.0375 × 0.50

557.51875

Round up to nearest hundredths place:

557.52

Your answer may vary depending on if you rounded your first answer (1115.0375), but it should be only a decimal or two off from my final answer.

Answer:

The point is (7,0).

Step-by-step explanation:

The equation of a linear function in point-slope form is as follows :

[tex]y-y_1=m(x-x_1)[/tex] ...(1)

Where

(x₁,y₁) are the coordinates of the point which  the line passes through it and (x,y).

Harold correctly wrote the equation y= 3(x–7)

or we can write it as :

y-0=3(x-7) ...(2)

Comparing equations (1) and (2), we get :

x₁ = 7 and y₁ = 0

So, the point is (7,0).

The correct option is (c).

Answer:

10.5 km

Step-by-step explanation:

this can be solved using Pythagoras theorem

The Pythagoras theorem : a² + b² = c²

where a = length

b = base

c =  hypotenuse

1² + 4² =

1 + 16 = 17

√17 = 4.123km

4² + 5²

16 + 25 = 41

√41 = 6.40 KM

total distance = 6.4 + 4.12 = 10.52

Answer:

g(x) = [tex]-\frac{2}{5} (10)^{x}[/tex]

Step-by-step explanation:

Looking at the equation of a Exponential Function:

The a-value [tex](\frac{2}{5})[/tex] determines whether the function reflects over the x-axis. If it's negative it reflects over the x-axis. If it's positive it stays over the x-axis.

Answer:

yellow = 5 bags

red = 4 bags

Step-by-step explanation:

two equations can be derived from the question

x + y = 9 equation 1

6x + 7y = 59 equation 2

where x = number of red onion bags

y =  number of yellow onion bags

Multiply equation 1 by 6

6x + 6y = 54 equation 3

subtract equation 3 from 2

y = 5

substitute for y in equation 1

x + 5 = 9

x = 9 - 5

x = 4
