I need help please i got stuck so please help me

Answer:

[tex]w=63[/tex]

Step-by-step explanation:

the equation to solve this is : [tex](w-8)+(2x-1)=180[/tex]

combine the first side of the equation so you get [tex]3w-9[/tex]

then add 9 on both sides

divide 3 by 189 which gets you 63.

plug 63 into the equation to double check

hope this helps! :))

Answer:

Yes, it is a linear equation. This equation is in y=mx+b form, which is a linear equation. To rearrange it into y=mx+b form, you'll just do y= -2x+8

To make a line, you only need two points, so here are two points that fit into the line of y= -2x+8:

(0,8) and (1,6)

Answer :x = 17

Step-by-step explanation:

The two angles you are given equal 180 degrees.

3x + 5 + 8x - 12 = 180

11x - 7 = 180

11x = 187

x = 17

Answer:

x = 17

Step-by-step explanation:

angles Q and M are right angles (they each measure 90 degrees)

there are 360 degrees inside any 4-sided polygon

add the following to solve for x:  

90 + 90 + 3x + 5 + 8x - 12 = 360

11x + 185 - 12 = 360

11x + 173 = 360

11x = 187

x = 187/11

x = 17

Answer:

49152

Step-by-step explanation:

The n th term of a geometric sequence is

[tex]a_{n}[/tex] = a₁ [tex]r^{n-1}[/tex]

where a₁ is the first term and r the common ratio

Here a₁ = 3 and r = [tex]\frac{-6}{3}[/tex] = - 2 , then

a₁₅ = 3 × [tex](-2)^{14}[/tex] = 3 × 16384 = 49152

Answer:

0,2,4,6

Step-by-step explanation:

The domain describes x values. So just plug in the x values into the equation to find the y vlaues.

30 by 30 = 900cm²

2.9m by 2.9m = 8.41m²

take m² change to cm²

10,000cm² = 1m²

8.41 × 10000 = 84100cm²

84100 ÷ 900

= 93.44 tiles

= 93 full tiles

Answer:

Graph F best represents the function.

The correct graph F is also attached below.

Step-by-step explanation:

Given the function

f(x) = 2(5)ˣ

We know that the value of the y-intercept can be determined by setting x = 0 and determining the corresponding value of y.

so substituting x = 0 in the function

y = 2(5)ˣ

y = 2(5)⁰

y = 2(1)      ∵ (5)⁰ = 1

y = 2

Thus, the y-intercept is (0, 2)

Let us check another point

now substitute x = 1

y = 2(5)ˣ

y = 2(5)¹

y = 10

Thus, the value of y = 10 at x = 1

So, we have to two points:

Now, if we carefully observe, we can easily figure out that the graph F represents the function f(x) = 2(5)ˣ.

Because the graph F has a y-intercept (0, 2) and also the point (1, 10) is validating the graph.

Therefore, graph F best represents the function.

The correct graph F is also attached below.

Answer:

d

Step-by-step explanation:

when fractions have the same whole which here is 9 you can just look at the first letters

so one is the smallest

Answer:

1/9 or D

Step-by-step explanation:

8/9 = About 0.89 = 89%

5/9 = About 0.56 = 56%

2/9 = About 0.22 = 22%

1/9 =  About 0.11 = 11%

The reason it is D is that it has a low fraction, decimal number, and percent.

Answer:

[tex]\approx 45.1\:\mathrm{w/\: some \: MOE}[/tex]

Step-by-step explanation:

The area of [tex]ABCD[/tex] is comprised of two triangles, so we can find the area of both triangles and add them to get the total area of

Since the sum of the interior angles of a triangle add up to [tex]180^{\circ}[/tex], we have:

[tex]\angle C=180-44-38=\fbox{$98^{\circ}$}[/tex].

The Law of Sines is given as:

[tex]\frac{\sin A}{a}=\frac{\sin B}{b}=\frac{\sin C}{c}[/tex] for any triangle.

Therefore, we have the proportion:

[tex]\frac{\sin 98^{\circ}}{10}=\frac{\sin 44^{\circ}}{BC},\\BC=\frac{10\cdot \sin 44^{\circ}}{\sin 98^{\circ}},\\BC\approx 7.01[/tex].

Now that we have two sides of a triangle and the angle between them, we can use [tex][\triangle]=\frac{1}{2}ab\sin C[/tex]  to find the area of [tex]\triangle CBD[/tex]:

[tex][CBD]=\frac{1}{2}\cdot 10\cdot 7.01 \cdot \sin 38^{\circ},\\\\\left [CBD]\right\approx 21.58[/tex].

Since [tex]\triangle ABD[/tex] is a right triangle, we can use basic trig rules for a right triangle to solve for the sides:

[tex]\sin 55^{\circ}=\frac{AB}{10},\\AB=10\sin 55^{\circ},\\AB\approx 8.19[/tex],

[tex]\sin 35^{\circ}=\frac{AD}{10},\\AD=10\sin 35^{\circ},\\AD\approx 5.74[/tex].

Therefore, the area of [tex]\triangle ABD[/tex] is:

[tex]\frac{1}{2}\cdot 8.19\cdot 5.74\approx 23.49[/tex].

The area of [tex]ABCD[/tex] is then

[tex]21.58+23.49=45.07=\fbox{$45.1$}[/tex].

[tex]\bigstar[/tex] Note that intermediate results were rounded during this calculation. Therefore, there is a small margin of error when rounding to final answer to one decimal place. I recommend plugging in values for yourself using all equations I wrote above, then rounding only your final answer to one decimal place as requested by the problem.

Answer:

14

Step-by-step explanation:

72% of 50 = 36

50 - 36 = 14

Answer:

For the first question:

[tex]\sqrt{\frac{15x}{x^3}}\\= \sqrt{\frac{15}{x^2}}\\= \frac{\sqrt{15}}{x}\\[/tex]

And the second

[tex]\frac{\sqrt{x^2}}{\sqrt{x^3}}\\= (x^2)^{\frac{1}{2} }(x^3)^{\frac{-1}{2} }\\= x^1 \times x^{\frac{-3}{2} }\\= x^{\frac{2}{2}} \times x^{\frac{-3}{2} }\\= x^{-\frac{1}{2}}\\= \frac{1}{\sqrt{x}}[/tex]

Answer:

[tex] \sqrt{ \frac{15x}{ {x}^{3} } }= \sqrt{ \frac{15}{ {x}^{2} } } = \frac{ \sqrt{15} }{ \sqrt{ {x}^{2} } } = \frac{ \sqrt{15} }{x} \\ [/tex]

[tex] \frac{ \sqrt{ {x}^{2} } }{\sqrt{{x}^{3}}} = \frac{ {x}^{ \frac{2}{2} } }{ {x}^{ \frac{3}{2}}}= \frac{x}{ {x}^{(1 + \frac{1}{2}) } } = \frac{x}{x \times {x}^{ \frac{1}{2} } } = \frac{1}{ \sqrt{x} } \: \\ [/tex]

Answer:

x = 32°

Step-by-step explanation:

The consecutive angles in a parallelogram are supplementary.

∠ A and ∠ D are consecutive angles, then

131 + 17 + x = 180

148 + x = 180 ( subtract 148 from both sides )

x = 32°

Answer:

the cost of each share in the software company and cost of each share in the biotech firm is $30 and $95 respectively

Step-by-step explanation:

The computation of the cost of each share in the software company and cost of each share in the biotech firm is as follows:

Let us assume the cost of each share in the software company be x

And, for biotech it would be y

Now

65x + 43y = $6,035 .......(i)

11x + 43y = $4,415 ......(ii)

Now subtract equation 2 from equation 1

54x = $1,620

x = $30

Now put the x value in any of the above equation

65($30) + 43y = $6,035

$1,950 + 43y = $6,035

43y = $6,035 - $1,950

43y = $4,085

y = $95

Hence, the cost of each share in the software company and cost of each share in the biotech firm is $30 and $95 respectively
