Answer:

X=12

Step-by-step explanation:

First, take the term out parenthesis being careful to manage the sign of individual term carefully :

x+42+3x=90

Next , subtract 42 from each side of the equation to isolate the x term while keeping equation balance :

x+42-42+3x=90-42

x+0+3x=48

x+3x=48

(1+3)x=48

4x=48

Now, Divide both side of equations by 4 to slove of x while keeping equation balance :

4x/4=48/4

x=12

Here,

(12+42)+3*12=90

54+36

90

Answer:

141°

Step-by-step explanation:

An octagon has 8 sides and 8angles so the sum of its interior angles is: (8-2)×180= 1080°

5x+133+16+126+162-12+30=1080°

5x=625

x=125°

x+16=141°

Answer:

4π

Step-by-step explanation:

the area (A) of each shaded sector is calculated as

A = area of circle × fraction of circle

the angle subtended at the centre of each sector = 180° - 160° = 20°

then area of 2 sectors

= 2 × π × 6² × [tex]\frac{20}{360}[/tex]

= 2 π × 36 × [tex]\frac{20}{360}[/tex]

= 2π × [tex]\frac{20}{10}[/tex]

= 2π × 2

= 4π

7874

7874 rounded to 1 sf

if the previous digit is 5 or more round up, if not keep it as it is.

1 sf= 8000

therefore, 7874 rounded to 1 sf is 8000.

Answer:

8000

Step-by-step explanation:

Since the leftmost 7 is in the thousands place, you need to round the number to the nearest thousand. The digit to the right of the first 7 is an 8, so 7 goes up 1 to 8.

Answer: 8000

The solution of the graphed system of equations y = -x² + x + 2 and y = -x + 3 is (1,2)

The system of equations is given as:

y = -x² + x + 2

y = -x + 3

From the graph in the complete question, we have the following point of intersection between the equations

(x,y) = (1,2)

The point of intersection between the equations is the solution

Hence, the solution of the graphed system of equations is (1,2)

Answer:

Random, because he surveyed 30 random shoppers

Answer:

Yes it is possible

Step-by-step explanation:

Now, put it all together (9). Sin (A + B) is the two parts of the opposite - all divided by the hypotenuse (9). Putting that into its trig form: A very similar construction finds the formula for the cosine of an angle made with two angles added together.

Step-by-step explanation:

the slope is always the ratio "y coordinate change / x coordinate change" when going from one point of the line to another.

so, when going from (-2, 3) to (-3, 1)

x changes by -1 (from -2 to -3).

y changes by -2 (from 3 to 1).

therefore, the slope is

-2/-1 = 2/1 = 2

Answer:

The vertex is (5, -9).

Step-by-step explanation:

One way of approaching this problem consists of finding the roots.  Seet the quadratic equal to zero and solve for x:  {2, 8}.

The axis of symmetry is exactly halfway between 2 and 8:  x = 5.

Now find the y-component of the vertex by evaluating f(5):

f(5) = (5 - 8)(5 - 2) = -9

The vertex is (5, -9).  This is the minimum value of the function.  The graph of this quadratic opens up.

The speed of the wave whose wave equation :

y(x,t) =[tex](2.00 mm)[(20 m^{-1} )x - (4.0 s^{-1} ) t]^{0.5}[/tex]  is 0.20 m/s

speed = 0.20 m/s

The wave equation is a linear second-order partial differential equation which describes the propagation of oscillations at a fixed speed in some quantity y.

The wave equation is given by:

y(x,t) =[tex](2.00 mm)[(20 m^{-1} )x - (4.0 s^{-1} ) t]^{0.5}[/tex] .......................(1)

As we know that the standard form of wave equation is of the form is

On Comparing it with equation (1)

we have,

angular number, k=20

and, angular frequency, ω=4.0 rad/s.

Thus, the speed of the wave is

v=[tex]\frac{\omega}{K}[/tex]

=[tex]\frac{(4.0 rad/s) }{(20 m^{-1}) }[/tex]

=0.20 m/s

The speed of the wave of the wave equation

y(x,t) =[tex](2.00 mm)[(20 m^{-1} )x - (4.0 s^{-1} ) t]^{0.5}[/tex]  is 0.20 m/s
