Answer:
b=100
a=80
c=100
Step-by-step explanation:
to find b we know that in a straight angle there is 180 degrees and since we already know that one side is 80 degrees we just need to substract 180 by 80 to get 100 degrees.
since its parallel lines we can confirm that 80degrees and r are coresponding angles so r=80.Which also means a and r are alternate angles so a=80.
Lastly to find c we need to do the same thing as we did with b. Which means c=100

Michael is leaving a 15% tip for his waitress. What percent of the
original price will he pay? Write your answer as a percent, decimal,
and fraction.
Answers
Answer:
As a percent: 115%
As a decimal: 1.15
As a fraction: [tex]\frac{23}{20}[/tex]
Step-by-step explanation:
Percentages
Suppose Michael spends some amount of money on food, and that money is set at 100%. He leaves a 15% tip for the waitress.
Thus, he is really paying 100%+15% = 115% of the original price.
To express a percentage as a decimal, we just divide by 100:
115% = 115/100 = 1.15
The same division should be simplified instead of operated to express the percentage as a fraction:
115% = [tex]\frac{115}{100}[/tex]
Simplifying by 5:
115% = [tex]\frac{23}{20}[/tex]
Summarizing:
As a percent: 115%
As a decimal: 1.15
As a fraction: [tex]\frac{23}{20}[/tex]

You are biking to the park. After six minutes 40% of the distance still need to be traveled. How long does it take to bike to the park? We write an equation that represents the percent white of the distance that still needs to be travel Dr. X minutes. And equation is Y = ______ it takes ______ minutes to bike to the park?
Answers
Answer:
[tex]y = (100-10x)\%[/tex]
It takes 10 minutes to the park.
Step-by-step explanation:
Given that:
Time taken = 6 minutes
Distance left to be traveled = 40%
To find:
The equation to represent the distance [tex]y[/tex], that still needs to be traveled after [tex]x[/tex] minutes.
Solution:
As per given statement, distance traveled in 6 minutes = 60%
We can say that:
Distance traveled each minute = [tex]\frac{60\%}{6}[/tex] = 10%
After 1 minute, distance traveled = 10%
Distance left = 100 - 10 = 90%
After 2 minutes, distance traveled = 20%
Distance left = 100 - 20 = 80%
After [tex]x[/tex] minutes, distance traveled = 10[tex]x[/tex]%
Distance left, [tex]y[/tex] = (100 - 10[tex]x[/tex])%
Therefore, the equation is:
[tex]y = (100-10x)\%[/tex]
Time taken by the bike to reach to the park can be found by putting [tex]y[/tex] = 0 (i.e. distance left to be traveled = 0)
[tex]0 = 100 -10x\\\Rightarrow 10x = 100\\\Rightarrow x = \bold{10\ minutes}[/tex]

Answers
Given:
The vertices of a triangle are P(4,1), Q(2,-8), and R(-8,1).
To find:
The vertices of the image reflected across the y-axis.
Solution:
The vertices of a triangle are P(4,1), Q(2,-8), and R(-8,1). It is reflected across the y-axis.
If a figure is reflected across the y-axis, then
[tex](x,y)\to (-x,y)[/tex]
Using this rule, we get
[tex]P(4,1)\to P_1(-4,1)[/tex]
[tex]Q(2,-8)\to Q_1(-2,-8)[/tex]
[tex]R(-8,1)\to R_1(8,1)[/tex]
So, the vertices of the image are [tex]P_1(-4,1), Q_1(-2,-8), R_1(8,1)[/tex].
Therefore, the correct option is B.
Note: Options are not in proper form.

Find the length of side x in the simplest radical form with a rational denominator
Answers
Answer:
The value of x = 1
Step-by-step explanation:
Given
hypotenuse = √2 angle Ф = 45°To determine
x = ?
Using the trigonometric ratio
cos Ф = adjacent / hypotenuse
here
Ф = 45°
adjacent of 45° = x
hypotenuse = √2
so substituting Ф = 45° adjacent = x and hypotenuse = √2 in the equation
cos Ф = adjacent / hypotenuse
[tex]\cos \left(45^{\circ \:}\right)=\frac{x}{\sqrt{2}}[/tex]
switch sides
[tex]\frac{x}{\sqrt{2}}=\cos \left(45^{\circ \:}\right)[/tex]
Multiply both sides by 2
[tex]\frac{2x}{\sqrt{2}}=2\cos \left(45^{\circ \:}\right)[/tex]
[tex]\sqrt{2}x=\sqrt{2}[/tex] ∵ [tex]\cos \left(45^{\circ \:}\right)=\frac{\sqrt{2}}{2}[/tex]
Divide both sides by √2
[tex]\frac{\sqrt{2}x}{\sqrt{2}}=\frac{\sqrt{2}}{\sqrt{2}}[/tex]
[tex]x=1[/tex]
Therefore, the value of x = 1

Mrs.Smith has two similiar recycling bins in her office. The dimension of the smaller bin can be found by dilating the dimension of the larger bin by scale factory of 0.75
Answers
Answer:
The dimension of the larger bin is x and the smaller bin is [tex]0.75x[/tex].
Step-by-step explanation:
Let the dimension of the larger bin is x.
It is given that the dimension of the smaller bin can be found by dilating the dimension of the larger bin by a scale factor of 0.75
In order to find the dimension of the smaller bin multiply the dimension of the larger bin by 0.75
[tex](x)(0.75)=0.75x[/tex]
Hence, the dimension of the larger bin is x and the smaller bin is [tex]0.75x[/tex].

It took 4 hours to drive 240 miles. At this rate, how long does it take to drive 90 miles? A.60 hours B.6 hours C.2 2/3 hours D. 1 1/2 hours
Answers
Answer:
D. 1 1/2 hours
Step-by-step explanation:
First, we need to find the unit rate to then multiply it by 90. to find the unit rate I did 240 miles divided by 4 hours to get 60 miles per hour. So we know we need at least 1 hour to get the 60 miles and to get 90 miles we need to add 30. Since 30 is half of 60 we can just take half of 1 hour which is 30 minutes. we add it together and get 1 hour and 30 minutes, or 1 hour and a half.
Time taken to cover 90 miles is 1.5 hours
Given that;Time taken to cover 240 miles = 4 hours
Find:Time taken to cover 90 miles
Computation:Time taken to cover 90 miles = [90 / 240]4
Time taken to cover 90 miles = [360 / 240]
Time taken to cover 90 miles = 1.5 hours

What is the measure of triangle X in degree
Answers
Answer:
A.) 40°
Step-by-step explanation:
A triangle is equal to 180°
Angle X and Y has the same angle, so both have 70°.
So:
70° × 2= 140°
To find the degree of the last angle, subtract the known degree, which is 140°, from the overall degree, which is 180°.
So:
180° - 140°= 40°
Answer= 40°

Answers
Answer:
Add to eliminate y.Step-by-step explanation:
Given the equations
-9x + y = 71.... 1
-x - y = -1 .... 2
Using elimination method we can eliminate y first since they have the same coefficient.
To do that we will need to add up both equations. We are adding because the coefficient of y in both equations has different signs. If they have the same sign, we would have subtracted.
Hence the correct option in this case is to add to eliminate y.
