Answer 1

4*((7x-6)+(4x-3))=360

7x-6+4x-3=90

11x=99

x=9

∠ACD = (7x-6)=7*9-6 = 57°

Answer 2
BD is the angle bisector of ∠ADC
Therefore ∠ADC=(8x-6)°

Same for ∠DCB, AC bisects ∠DCB
Therefore ∠DCB=(14x-12)°

Because AD//BC, ∠DCB+∠ADC=180°
i.e. 22x-18=180
x=9

(-2,-19) and (-12,11) whats the slope

Answers

Answer: -3

Step-by-step explanation:

To find the slope, you can use the formula (y2-y1)/(x2-x1)

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

Given

x1=-2

y1=-19

x2=-12

y2=11

Substitute values into the formula

 (y2-y1)/(x2-x1)

=[(11)-(-19)]/[(-12)-(-2)]

=(11+19)/(-12+2)

=30/-10

=-3

The estimate for the first expression is [tex]\frac{1}{2}[/tex].The estimate for the second expression is 1.The estimate for the third expression is 0.

Given the following expression:

[tex]\frac{1}{8} + \frac{2}{5}[/tex][tex]\frac{13}{14} -\frac{1}{10}[/tex][tex]\frac{1}{12} + \frac{1}{20}[/tex]

To determine an estimate for each expression:

What is a fraction?

A fraction can be defined as a numerical quantity that is not expressed as a whole number. Therefore, a fraction is simply a part of a whole number.

The parts of a fraction

Generally, a fraction comprises two (2) main parts and these include:

Numerator: it's the upper part of a fraction.Denominator: it's the lower part of a fraction.

In this exercise, we would simplify and estimate the given expressions as follows:

Note: An estimate simply means an approximate value.

a. [tex]\frac{1}{8} + \frac{2}{5}=\frac{5+16}{40}=\frac{21}{40}[/tex]

For the estimate:

[tex]\frac{1}{8} + \frac{2}{5}=\frac{1}{2}[/tex]

b. [tex]\frac{13}{14} -\frac{1}{10}=\frac{130-14}{140} =\frac{116}{140} =0.83[/tex]

For the estimate:

0.83 ≈ 1

c. [tex]\frac{1}{12} + \frac{1}{20}=\frac{5-3}{60} =\frac{2}{60} =0.03[/tex]

For the estimate:

0.03 ≈ 0

Explanation:

The equation p = 100 – 5t represents the percent p of battery power remaining in a tablet after t hours.

Answers

Answer:

t=-p/5+20

Step-by-step explanation:

p=100−5t

Swap sides so that all variable terms are on the left hand side.

100−5t=p

Subtract 100 from both sides.

−5t=p−100

Divide both sides by −5.

−5t/5 = p - 100/-5

Dividing by −5 undoes the multiplication by −5.

t = p - 100/-5

Divide p−100 by −5.

t=-p/5+20

Answer:

[tex]\sqrt{61}[/tex] units

Step-by-step explanation:

We are given that

[tex]P_1=(-2,5)[/tex]

[tex]P_2=(4,0)[/tex]

We have to find the distance d (P1, P2) between the points P, and P2

We know that

Distance between  two points (x1,y1) and (x2,y2)  i

=[tex]\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

Using the formula

The distance d (P1, P2) between the points P, and P2

=[tex]\sqrt{(4-(-2))^2+(0-5)^2}[/tex]

The distance d (P1, P2) between the points P, and P2

[tex]=\sqrt{(4+2)^2+(-5)^2}[/tex]

The distance d (P1, P2) between the points P, and P2
