Answer:

Answer:C. y = x + 7

Step-by-step explanation:

everything on the left is 7 less then on the right

Answer:

d. None of these

Step-by-step explanation:

Hope it helps you in your learning process.

[tex] m\angle 1 + m\angle 2 + 90\degree = 360\degree [/tex]

[tex] m\angle 1 + m\angle 2 = 360\degree- 90\degree [/tex]

[tex] m\angle 1 + m\angle 2 = 270\degree [/tex]

Answer:

D. None of the above.

Step-by-step explanation:

Complementary are 90 degrees and supplementary are 180 degrees.

A full circle is 360 degrees, and since there is a right angle, that means that angle 1 and 2 make up 270 degrees total.

This means it is neither.

Answer:

[tex]\frac{2}{7}[/tex]

Step-by-step explanation:

Let x represent the unknown number.  

x ÷ [tex]\frac{1}{3}[/tex] = [tex]\frac{6}{7}[/tex]

To solve, we must multiply [tex]\frac{1}{3}[/tex] by [tex]\frac{6}{7}[/tex] .

[tex]\frac{1}{3}[/tex] * [tex]\frac{6}{7}[/tex] = [tex]\frac{2}{7}[/tex]

So, x = [tex]\frac{2}{7}[/tex]

Therefore, [tex]\frac{2}{7}[/tex] divided by [tex]\frac{1}{3}[/tex] equals [tex]\frac{6}{7}[/tex].

Answer : -302.6

Step-by-step explanation:

Answer:

K = 15

Step-by-step explanation:

From the question given above, the following data were obtained:

Sine x = 1/4

Cos² x = K / 16

K =?

Next, we shall determine the 3rd leg (i.e the adjacent) of the right angle triangle. This can be obtained as follow:

Sine x = 1/4

Sine x = Opposite / Hypothenus

Opposite = 1

Hypothenus = 4

Adjacent =?

Hypo² = Opp² + Adj²

4² = 1² + Adj²

16 = 1 + Adj²

Collect like terms

16 – 1 = Adj²

15 = Adj²

Take the square root of both side.

Adj = √15

Next, we shall determine Cos² x.

Adjacent = √15

Hypothenus = 4

Cos² x =?

Cos x = Adjacent / Hypothenus

Cos x = √15 /4

Square both side

Cos² x = (√15 /4)²

Cos² x = 15 / 16

Finally, we shall determine the value of K. This can be obtained as follow:

Cos² x = K / 16

Cos² x = 15 / 16

K / 16 = 15 / 16

K = 15

=====================================================

Work Shown:

Applying the tangent-secant theorem will allow us to solve for x

x*(x+5) = (x+2)^2

x^2+5x = (x+2)*(x+2)

x^2+5x = x^2+4x+4

5x = 4x + 4 ..... subtracting x^2 from both sides; terms cancel

5x-4x = 4

x = 4

------------------

Check:

Plug in x = 4

x*(x+5) = (x+2)^2

4*(4+5) = (4+2)^2

4*(9) = (6)^2

36 = 36

The answer is confirmed.

Answer:

8.48%

Step-by-step explanation:

Given that,

The estimated bill = $480

Actual costing of the bill = $524.50

We need to find the percent error in the bill. It can be calculated as follows :

[tex]\%=\dfrac{524.50-480}{524.50}\times 100\\\\\%=8.48\%[/tex]

So, the percentage error in the bill is 8.48%.

Answer:

177.6 g/mol

Step-by-step explanation:

The molecular weight of the substance is 177.55 g/mol.

Option B is the correct answer.

It is the conversion of one unit to another unit with its standard conversion.

Examples:

1 hour = 60 minutes

1 minute = 60 seconds

1 km = 1000 m

The molecular weight (MW) of the substance can be calculated by dividing the mass of the sample by the number of moles:

MW = mass/moles

MW = 0.03551 kg / 0.2000 moles

MW = 0.17755 kg/mol

However,

The answer is given in grams per mole, so we need to convert the result to g/mol.

So,

1 kg = 1000 g

MW = 0.17755 x 1000 g/mol

MW = 177.55 g/mol

Therefore,

The molecular weight of the substance is 177.55 g/mol.

Answer:

[tex]600, 900, 1350[/tex]

Step-by-step explanation:

Given

[tex]a = 400[/tex] -- initial subscribers

[tex]b = 1.5[/tex] -- growth factor

Required

Determine the number of subscribers in the next three months

To do this, we make use of:

[tex]y = ab^x[/tex]

In this case:

x is the number of months

y is the number of subscribers

So:

when x = 1;

[tex]y = ab^x[/tex]

[tex]y = 400 * 1.5^1[/tex]

[tex]y = 400 * 1.5[/tex]

[tex]y = 600[/tex]

when x = 2

[tex]y = 400 * 1.5^2[/tex]

[tex]y = 400 * 2.25[/tex]

[tex]y = 900[/tex]

when x= 3

[tex]y = 400 * 1.5^3[/tex]

[tex]y = 400 * 3.375[/tex]

[tex]y = 1350[/tex]

So, the next three number of subscribers is:

Answer:

The value of q that makes the expression a perfect square is q = 4.

Step-by-step explanation:

Perfect square:

A perfect square expression has the following format:

[tex](a - b)^2 = a^2 - 2ab + b^2[/tex]

In this question:

[tex]9x^2 - 12x + q[/tex] is a perfect square, we have to find the value of q.

First we have to find the value of a, looking at the equivalent formula above. So

[tex]a^2 = 9x^2[/tex]

[tex]a = \sqrt{9x^2}[/tex]

[tex]a = 3x[/tex]

Since the second term, which is -2ab, is -12x, we have that:

[tex]-2ab = -12x[/tex]

[tex]-2(3x)b = -12x[/tex]

[tex]-6xb = -12x[/tex]

[tex]6b = 12[/tex]

[tex]b = \frac{12}{6}[/tex]

[tex]b = 2[/tex]

q is b squared. So

[tex]q = b^2 = 2^2 = 4[/tex]

The value of q that makes the expression a perfect square is q = 4.

Answer:

When we subtract the second equation  x-2y=9 from the first equation  4x-2y=-2, we get the value of x = 11/5.

Therefore, the required result is:

x = 11/5

Step-by-step explanation:

Given

The first equation

[tex]-4x-2y=-2[/tex]

The second equation

[tex]x-2y=9[/tex]

Let us subtract the second equation from the first equation

[tex]-4x-2y=-2[/tex]

[tex]-[/tex]

[tex]\:\underline{x-2y=9}[/tex]

[tex]-4x - 2y - (x - 2y) = -2 - 9[/tex]

[tex]-4x -2y -x + 2y = -2-9[/tex]

[tex]-5x = -11[/tex]

divide both sides by -5

[tex]\frac{-5x}{-5}=\frac{-11}{-5}[/tex]

Simplify

[tex]x=\frac{11}{5}[/tex]

Thus, when we subtract the second equation  x-2y=9 from the first equation  4x-2y=-2, we get the value of x = 11/5.

Therefore, the required result is:

x = 11/5
