31.0 degrees

TanX wich is 30/50

same thing as 30 divided by 50

Answer:

x=2

Step-by-step explanation:

Primero, necesitamos calcular <<a>>

Sabemos que AD=BC y AB=CD porque lados opuestos congruentes

Entonces, vamos a calcular <<a>>.

Usamos AD y BC

2a-1=4a-15

suma 15 a ambos lados

2a+14=4

añada 2 en ambos lados

14=2a

divida

7=a

Ahora, usamos esta información para calcular <<x>>

Usamos CD=AB

2a-8=4x-2

pero sabemos que <<a>> es 7

entonces:

14-8=4x-2

6=4x-2

8=4x

2=x

<<x>> es 2

(¡lo siento mi español no es perfecto!

Step-by-step explanation:

Given

[tex] = 27^{ \frac{1}{3} } \times 16^{ \frac{ - 1}{4} } \\ = {3}^{3 \times \frac{1}{3} } \times 2 {}^\frac{ - 1 \times 4}{4} \\ = 3 \times - 2 \\ = - 6[/tex]

Hope it will help :)❤

Answer: the answer is  3

Step-by-step explanation:

This says to put " 3"  into 2x + 4 and then evaluate

So

2(3)  + 4  =

6 + 4  =

10

'x'  can be thought of as a "box" that contains some number.....in this case, the number is 3......!!!

Answer:

-10

Step-by-step explanation:

f(x) = 2x - 4

f(-3) = 2(-3) - 4

f(-3) = -6 - 4

f(-3) = -10

Answer:

Decreasing

Step-by-step explanation:

It is decreasing because it is being used.

Have a good day!!

Answer:

118° is given , so angle on a straight line =180°

therefore, 180°-118°=62°

the □(squared angle) indicates 90°

x°+62°+90°=180°

x°=180°-152°

x°=28°

if you want to recheck

28°+62°+90°=180°

Answer:

2 + x

2 + (x)

x + (2)

Switch them around.

Answer:

CD = 101°

Step-by-step explanation:

The secant- tangent angle DAB is hlf the difference of the intercepted arcs, that is

[tex]\frac{1}{2}[/tex] (CD - BD ) = 29° ( multiply both sides by 2 )

CD - BD = 58°, that is

CD - 43° = 58° ( add 43° to both sides )

CD = 101°

Answer:

f(x)=x-6 is your answer.

when x=0

f(0)=0-6=-6

similarly other too

Answer:

1. y=3x+0

2. y=-2x+1

3. y= -2/3x-4

4. y=0x+4

Answer:

A) 18

B)9

C)-2

Step-by-step explanation:

Replace the a,b or c with the give number. So let’s say it’s says 2 + a. It would be 2+3.

Answer:

D

Step-by-step explanation:

Remember, area equals width x height so you can set up this equation.

[tex]48x^8y^7=6x^2y^4 * w[/tex]

Solving for w,

[tex]\frac{48x^8y^7}{6x^2y^4} =w[/tex]

Simplifying,

[tex]8x^6y^3[/tex]

Thus, D is the answer

Answer:

$250.8

Step-by-step explanation:

13.4 = $2.85

13.4 x 15 = 111.0

111.0 = $42.75

111.0 x 6 = 666.0

666.0 - 26.0 = 640.0

$42.75 x 6 = $256.5

$2.85 x 2 = $5.07

$256.5 - $5.07 = $250.8

not gona lie this took forever lol

Hope this helps if so don't hesitate to 'Thanks' and/or 'brainliest' this answer!

The total cost of 640 liters of gas is $35.91.

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

Given that, Gas from a local station costs $2.85 per gallon (in US dollars).

We know that, 1 gallon = 3.785 liters

Tara's car gets 13.4 kilometers to the liter.

Number of liters of gas = 640/13.4

= 47.76 liters

Number of gallons = 47.76/3.785

= 12.6 gallons

Total cost = 12.6×2.85

= $35.91

Therefore, the total cost of 640 liters of gas is $35.91.

Answer:

[tex]n^{3} + 15n^{2} + 56n[/tex]

Step-by-step explanation:

First FOIL  (n + 7)(n + 8) and then distribute n

(n + 7)(n + 8) = [tex]n^{2} +15n + 56[/tex]

 n ([tex]n^{2} +15n + 56[/tex])

= [tex]n^{3} + 15n^{2} + 56n[/tex]

Answer:

30

Step-by-step explanation:

Answer:

40

Step-by-step explanation:

5/6 of 48

In math, when the word "of" is used, it means multiplication.

5/6 of 48 ---> 5/6 × 48 = 40

How much does 6 goes in 48? Anser is 8 since 6 × 8 = 48. So this means that 6 and 48 cancels out remaining 8 and 5. 5 × 8 = 40 which is your answer. Hope this helps, thank you :) !!

Answer:

Option B

Step-by-step explanation:

Answer:

[tex]Average\ Rate = \frac{104}{3}[/tex]

Step-by-step explanation:

Given

See attachment for table

Required

Determine the average rate of change over: 4≤x≤7.

Average rate of change is calculated as:

[tex]Average\ Rate = \frac{f(b) - f(a)}{b - a}[/tex]

Where:

[tex]a=4[/tex]

[tex]b = 7[/tex]

So:

[tex]Average\ Rate = \frac{f(b) - f(a)}{b - a}[/tex]

[tex]Average\ Rate = \frac{f(7) - f(4)}{7 - 4}[/tex]

[tex]Average\ Rate = \frac{f(7) - f(4)}{3}[/tex]

From that table:

f(4) =

f(7) =

So:

[tex]Average\ Rate = \frac{f(7) - f(4)}{3}[/tex]

[tex]Average\ Rate = \frac{108-4}{3}[/tex]

[tex]Average\ Rate = \frac{104}{3}[/tex]

Answer:

Answer:

9

Step-by-step explanation:

So the formula for a triangular pyramid is v=1/3bh

you plug in the values and you get 63=1/3(21)(h) and since you are finding the height, you get h=63*3/21

and then you check answers with

63=1/3(21)(9) which is true so the height is 9
