The measure of angle ABD is (0.15x+65) and the measure of angle CBD is(0.1x+28) . Find the value of x.

Answers

Answer:

x = 348

Step-by-step explanation:

The measure of angle ABD is (0.15x+65) and the measure of angle CBD is(0.1x+28) . Find the value of x.

0.15x + 65 + 0.1x + 28 = 180

0.25x + 93 = 180

0.25x = 180 - 93

0.25x = 87

x = 87/0.25

x = 348

Write the Quadratic Formula for the quadratic equation.

Answers

Answer:

[tex]x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}[/tex]

Step-by-step explanation:

Hello!

Let's start with the given equation and work our way towards x.

Solve for x[tex]ax^2 + bx + c = 0[/tex]

Divide both sides by a

[tex]a(x^2 + \frac bax + \frac ca) = 0[/tex]        [tex]x^2 + \frac bax + \frac ca = 0[/tex]

Move c/a to the other side

[tex]x^2 + \frac bax = -\frac ca[/tex]

At the step, we have to use the Completing the Square method.

[tex]x^2 + \frac bax + (\frac{b}{2a})^2 = -\frac ca + (\frac b{2a})^2[/tex][tex]x^2 + \frac bax + \frac{b^2}{4a^2} = -\frac ca + \frac {b^2}{4a^2}[/tex][tex](x + \frac b{2a})^2= -\frac ca + \frac{b^2}{4a^2}[/tex]

Multiply -c/a by 4a and add the two fractions

[tex](x + \frac b{2a})^2= \frac{b^2 - 4ac}{4a^2}[/tex]

Square Root both sides

[tex]\sqrt{(x + \frac b{2a})^2}= \sqrt{\frac{b^2 - 4ac}{4a^2}}[/tex][tex]x + \frac b{2a} = \pm\frac{\sqrt{b^2 - 4ac}}{2a}}[/tex]

Subtract b/2a

[tex]x = \pm \frac{ \sqrt{b^2 - 4ac}}{2a} - \frac b{2a}[/tex][tex]x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}[/tex]

And that's the derivation of the Quadratic Formula.

Find the value of x.

Answers

Answer:

50

Step-by-step explanation:

The upper left hand arc is also 130

The lower right hand arc is also x

A circle all the way around from some starting point is 360 degrees.

x + x + 130 + 130 = 360            Equation. Combine like terms.

2x + 260 = 360                         Subtract 260 from both sides

2x = 360 - 260                    

2x = 100                                    Divide by 2

x = 100/2

x = 50

Answer:

774.25

Step-by-step explanation:

8.75 becomes .0875 because it is 8.75%/100%

711.95 x .0875 = 62.295625

add the cost (711.95) and the tax (62.295625)

711.95 + 62.295625 = 774.245625

rounded = 774.25

how do we add fractions

Answers

find the common denominator between the two fractions and change the numerator

Answer:

you have to find a common denominator and then add.

Step-by-step explanation:

for example 2/4 + 4/12

you find the common denominator in this case it would be i will use 4 so 2/4 would stay the same and 4/12 would change to 1/3

*make sure to do the same thing to the numerator to so if you are dividing your denominator by 2 also do the numerator

now you have to add

2/4 + 4/12 = 6/12 (the denominator stays the same)

6/12 can be simplified (if you are asked to simplify) so it is 1/6

C. 244°

Step-by-step explanation:

Angle formed by two tangents is equal to half of the difference of intercepted arcs:

m∠C = 1/2(arcAXB - arcAB)64° = 1/2(mAXB - mAB)mAXB - mAB = 128°

The sum of the same two arcs is a full circle:

mAXB + mAB = 360°

Add the two equations together:

2mAXB = 360° + 128°2mAXB = 488°mAXB = 244°

Correct choice is C
