If Tim had lunch at $50.50 and he gave 20% tip, how much did he spend?
Answer:
Tim spent $60.60 for his lunch.Step-by-step explanation:
The tip is 20% of what he paid for lunch. Hence
tip = 20% of 50.50 = (20/100)*50.50 = 101/100 = $10.10
Total spent
50.50 + 10.10 = $60.60
So hence, Tim spent $60.60 for his lunch.

Angelina wants to prove that vertical angles are congruent. She uses the diagram below to formulate her proof.
Angelina has one step wrong in her proof. The steps of her proof are shown below. Mark the step that is INCORRECT.
A.
Linear pairs of angles are complementary, hence, m∠2 + m∠3 = 90°.
B.
Subtracting m∠3 from both sides of the above equation gives m∠2 = m∠4.
C.
In my proof, I used m∠2 + m∠3 = m∠3 + m∠4 to justify linear pairs.
D.
By definition of congruent angles, ∠2 ≅ ∠4. This will show that ∠2 and ∠4 are veritcal angles.
Answer:
Option (A)
Step-by-step explanation:
Correct proof to prove the vertical angles are congruent :
1). Linear pairs of angles are supplementary.
m∠2 + m∠3 = m∠3 + m∠4
2). By subtracting m∠3 from both the sides of the above equation.
3). By definition of congruent angles, ∠2 ≅ ∠4. This will show that ∠2 and ∠4 are vertical angles.
Therefore, Option (A) is incorrect in which Angelina showed that linear pairs of angles are complementary.
Prior to the 2008 Republican primary for President, the December 21, 2007 Grand Haven Tribune had an article about results from a poll of 621 likely Michigan Republican voters. Quoting from the article: The survey of 621 likely Republican primary voters shows Romney at 21 percent, Huckabee at 19 percent, Guiliani at 12 percent and John McCain at 10 percent. Ron Paul and Fred Thompson each got 4 percent, while Duncan Hunter and Tom Tancredo each got 1 percent.
Required:
a. What is the sample size?
b. Make a frequency table of the results that includes both frequencies (counts) and relative frequencies
Answer:
a
The sample size is n = 621
b
Voters Relative Frequency Frequency
Romney 0.21 130
Huckabee 0.19 118
Guiliani 0.12 75
John McCain 0.10 62
Ron Paul 0.04 25
Fred Thompson 0.04 25
Duncan Hunter 0.01 6
Tom Tancredo 0.01 6
Undecided votes 0.28 174
Step-by-step explanation:
From the question we are told that
The number of voters is n = 621
The voter election aspirants and their relative frequency are
Romney , 0.21
Huckabee , 0.19
Guiliani , 0.12
John McCain ,0.10
Ron Paul , 0.04
Fred Thompson 0.04,
Duncan Hunter 0.01
Tom Tancredo 0.01
Undecided votes 0.28
This undecided vote is used to represent votes that did not count and it is obtained by subtracting the other relative frequencies from 1 (i.e 100%)
Generally the frequency is mathematically represented as
Romney , 621 * 0.21 = 130
Huckabee , 621 * 0.19 = 118
Guiliani , 621 * 0.12 = 75
John McCain 621 * 0.10 = 62
Ron Paul , 621 * 0.04 = 25
Fred Thompson 621 * 0.04 = 25
Duncan Hunter 621 * 0.01 = 6
Tom Tancredo 621 * 0.01 = 6
Undecided votes 621 * 0.28 = 174
So the table is
Voters Relative Frequency Frequency
Romney 0.21 130
Huckabee 0.19 118
Guiliani 0.12 75
John McCain 0.10 62
Ron Paul 0.04 25
Fred Thompson 0.04 25
Duncan Hunter 0.01 6
Tom Tancredo 0.01 6
Undecided votes 0.28 174

The function shown on the graph has the same rate of change, but a higher starting point
Fine the diagram needed attached.
The rate of change of the line is the slope of the line. The standard equation of a line is expressed as y = mx + b;
m is the rate of change or slopeGiven the equation y = 5x + 5, the rate of change of the expression is 5.
For the given graph, the slope of the graph is expressed as:
(2, 4) and (0, -6)
m = -6-4/0-2
m =-10/-2
m = 5
Hence the rate of change of the graph is 5.

write an equation of a line through (5,6) and perpendicular to the line through (4,8) and (-2,-18)
need this for test
Answer:
[tex]y-6=-\frac3{13}(x-5)[/tex]
Step-by-step explanation:
Get the slope of the line between the two points. As usual, [tex]m= \frac{\Delta y}{\Delta x}= \frac{8-(-18)}{4-(-2)}=\frac{8+18}{4+2}=\frac{26}{6}=\frac{13}3[/tex]
You want the perpendicular to it, so take it's inverse and change its sign:
[tex]m_p=-\frac3{13}[/tex]
At this point, it's just using the point-slope form, and you're done - unless you're required to provide the line in a specific way, which usually means just crunching numbers and rewriting the equation
[tex]y-y_0=m_p(x-x_0)\\y-6=-\frac3{13}(x-5)[/tex]
Answer:
y=-3/13x+7.15384615385

13/3
The slope of the other line is 13/3
To find the slope of our line we can do the opposite reciprocal of 13/3 which is -3/13.

I cant figure thia on out
Answer:
8r + 9p
Step-by-step explanation:
Combine like terms. Like terms are terms with the same variables as well as the same amount of said variable.
In this case, combine 12p with -3p
8r + 12p - 3p
8r + (12p - 3p)
8r + 9p
8r + 9p is your answer.
~
While adding such algebraic expressions, we combine the like terms which contains the same variables infact same degree of variables.
Given expression:
8r + 12p - 3pHere 12p and 3p are like terms because they are having same variable that is p. So, we can compute any operation like hear it's subtraction.
➝ 8r + (12p - 3p)
➝ 8r + 9p
Now no more like terms are there, So the final answer is 8r + 9p. And we are done!

niña+niño niño+perro niña+perro
51kg 46kg 41kg
Resolviendo el sistema de ecuaciones veremos que:
niña = 23kgniño = 28kgperro = 18kg.¿Como resolver el sistema de ecuaciones?
Aqui tenemos el sistema de ecuaciones:
Niña + niño = 51kg
Niño + perro = 46 kg
Niña + perro = 41kg
Para resolver esto, lo primero que debemos hacer es aislar una variable en una de las ecuaciones, por ejemplo, podriamos aislar "perro" en la tercera:
perro = 41kg - niña
Ahora reemplazamos eso en la segunda para obtener:
niño + (41kg - niña) = 46kg
niño - niña = 46kg - 41kg = 5kg
niño = niña + 5kg
Ahora logramos obtener la variable "niño" en terminos de la variable "niña". Podemos reemplazar esto en la primera ecuacion del sistema.
niña + niño = 51kg
niña + (niña + 5kg) = 51kg
2*niña = 51kg - 5kg = 46kg
niña = 46kg/2 = 23kg.
Ahora que sabemos esto, usamos las otras ecuaciones para encontrar el peso del niño y el perro:
niño = niña + 5kg = 23kg + 5kg = 28kg
perro = 41kg - niña = 41kg - 23kg = 18kg.

Carlos started a business growing palm trees in South Florida.
The function t(s) = 3s + 20 represents the
number of palm trees that grew, where s is the
number of seeds he planted.
The function s(d) = 20d represents the number
of seeds he plants per day, where d represents
the number of days.
Write a composite function that represents
how many palm trees Carlos can expect to
grow over a certain number of days.
Answer:
t(d) = 60d + 20
where t(d) is the number of palm trees grown, and d is the number of days
Step-by-step explanation:
Given function:
t(s) = 3s + 20
where:
t(s) = number of palm trees growns = number of seeds plantedGiven function:
s(d) = 20d
where:
s(d) = number of seeds planted per dayd = number of daysTo determine the composite function that represents how many palm trees Carlos can expect to grow over a certain number of days, simply substitute s = 20d into t(s) = 3s + 20:
⇒ t(d) = 3(20d) + 20
⇒ t(d) = 60d + 20
where t(d) is the number of palm trees grown, and d is the number of days.
Maximo likes to eat cookies for breakfast every day. He eats 2 cookies per day. Three days after opening a box of cookies, there are 6 cookies left on the box. How many cookies were there at the start?
Answer:
There were 12 cookies at the start
Step-by-step explanation:
Since Maximo likes to eat 2 cookies per day, after three days, he would have eaten 6 cookies. There are 6 cookies left after 3 days, so 6(amount he ate) + 6(amount of cookies left) is 12.
Measure each angle. Then classify each angle as acute, right, obtuse, or straight.
Answer:
Before solving these, we must know;
· A 90° angle forms a right angle.
· A 180° angle forms a straight angle.
· Any angle greater than a 90° angle is considered an obtuse angle (x > 90 = obtuse).
· Any angle less than a 90° angle is considered an acute angle (x < 90 = acute).
(Use a protractor to measure each angle)Now just eyeing these, I can tell that;
1. Is acute, because it looks like it is smaller than a 90° angle(right angle).
2. Is straight, because it looks fairly like a straight line(which measures 180°).
3. Is obtuse, because it looks greater than a 90° angle(right angle).
4. Is right, because it looks exactly like a 90° angle(right angle).
Steps on how to use a protractor;Align the dot in the center of the protractor(which has labeling measurements of inches/centimetres) with the intersection of the angles. It should be straight on the line of the angle you are measuring.Use the inner-band of the protractor when measuring an angle that is slanted to the right.Use the outer-band of the protractor when measuring an angle that is slanted to the left.An executive wishes to take out a $1,200,000 mortgage.

What is simple interest?It is given by:
SI = (P x R x T) / 100
P = principal amount
R = rate
T = time
We have,
P = $1,200,000
R = 1.95%
T = 20 years
SI = (P x R x T) / 100
SI = (1200000 x 1.95 x 20) / 100
SI = (1,200,000 x 195 x 20) / 100 x 100
SI = 120 x 195 x 20
SI = $4,68,000
