Jayden goes out to eat with his friend, at the local diner. He orders a chicken quesadilla for $11.00. If he plans on leaving a 20% tip, for the server, how much should he leave?
Answer:
$13.20 or $2.20
Step-by-step explanation:
Since percents are decimals, we can figure out the tip by multiplying the total by the decimal percent.
11 x .20 = 2.2
Now the answer depends on what you need the answer to be. if you need the total, it's $13.20.
If you need the tip, it's $2.20.
Faith purchases a car for $27,500. The
value of the car will depreciate each
year at a rate of 12.4%. What is the
approximate equivalent monthly
depreciation rate, to the nearest tenth
of a percent?
Help please tell the explanation I’ll give brainleist
Answer:
To the nearest tenth of a percent, the approximate equivalent monthly depreciation rate is 1.0%
Step-by-step explanation:
From the question, we have a per annum decrease of 12.4%
what this mean is that, yearly, we expect a decrease of 12.4%
To get the monthly decrease value, we have to divide this given value by the number of months in a year which is 12
Thus, we have it that;
12.4%/12
= 1.0%
To the nearest tenth, the monthly decrease percentage is 1.0%

The angles in a triangle are in the ratio 1 : 2 : 3
Show that the triangle is a right-angled triangle
Answer:
see explanation
Step-by-step explanation:
sum the parts of the ratio, 1 + 2 + 3 = 6 parts
Divide 180° ( sum of angles in a triangle ) by 6
180° ÷ 6 = 30° ← value of 1 part of the ratio , then
2 parts = 2 × 30° = 60°
3 parts = 3 × 30° = 90°
The angles in the triangle are 30°, 60°, 90°
Then the triangle is right angled
Answer:
The angles are 30°, 60° and 90°.Step-by-step explanation:
Hint : sum of the angles in triangle = 180°.The triangle is a right-angled triangle.Answer:Let missing angles be [tex]x[/tex], [tex]2x[/tex].
As the triangle is right-angled triangle.
[tex]x + 2x + {90}^{o} = {180}^{o} [/tex]
[tex]3x = {180}^{o} - {90}^{o} [/tex]
[tex]3x = {90}^{o} [/tex]
[tex]x = \frac{90 ^{o} }{3} [/tex][tex]x = {30}^{o} [/tex]
[tex]2x = 30 \times 2 \\ = {60 }^{o} [/tex]
Check:30° + 60° + 90° = 180°.Hope it is helpful....PLEASE HELP 26 POINTS AND BRAINLIEST GOES OUT TO CORRECT DON ANSWER IF YOU DO NOT KNOW OR DO NOT GUESS PLEASE SHOW WORK ALSO!!!!!!!!!!
Answer:
Mean - 89
Median - 90.5
Mode - 89 or 92
Q1 - 84.5
Q3 - 96.5
IQR - 12
Step-by-step explanation:
A mean is an average. Just add all numbers then divide by how many numbers there are.
A median is a middle. Just arrange the numbers from smallest to largest and locate the middle value.
A mode is the number that appears most often. Count how many of each number there is.
Q1 is the middle of the lower half of the data.
Q3 is the middle of the upper half of the data.
IQR is the difference between Q3 and Q1. (subtract)

Answer:
equation: 28 = 2h+ h + h or you could say 28 = 4h
h= 7
Step-by-step explanation:
since both lines are the same length they equal each other.
to get h = 7 you have to solve the equation you made.
28 = 4h
28/4 = 4h/4
7 = h

Beth made wristbands and belts for a craft sale. She sold 30 of these items. Each wristband sold for $5.50. Each belt sold at $8.75. If Beth made $204 at the craft sale, how many wristbands did she sell? How many belts did she sell? Write and solve a system of equations to solve the problem. Show work.
✿Answer:
Both sold 18 wristbands and 12 belts✂----------------------
Let, number of wristbands = x
number of belts = y
[tex]x+y=30[/tex] ➞ [tex]x~5.5[/tex]
[tex]5.50x+8.75y=204[/tex] [tex]x1[/tex]
[tex]5.50x+5.5y=165\\5.5x+8.75y=204\\---------\\-3.25y=-39[/tex]
[tex]y=-39/3.25[/tex]
[tex]y=12[/tex]
[tex]x=30-12=18[/tex]
[tex]So, Both~ sold ~18 ~wristbands ~and ~12~ belts[/tex].

Rule 1: Multiply by 3 starting from 1. Rule 2: Add 8 starting from 4. Select the option that correctly shows the first 5 terms of each sequence.
A) First sequence: 1, 3, 9, 27, 81 and second sequence: 4, 12, 20, 28, 36
B) First sequence: 1, 3, 9, 12, 48 and second sequence: 0, 4, 12, 20, 28
C) First sequence: 1, 4, 7, 10, 13 and second sequence: 4, 12, 20, 28, 36
D) First sequence: 1, 3, 9, 12, 36 and second sequence: 0, 8, 16, 24, 32
Answer:
A
First sequence: 1, 3, 9, 27, 81
Second Sequence: 4, 12, 20, 28, 36
Step-by-step explanation:
It is not B, bc it does not multiply correctly at the #12, it is supposed to be 27 since 9 x 3 = 27. And the second sequence starts with 0 but it is supposed to start with 4.
It is not c bc it does not even multiply by 3 but adds by 3. Second sequence is technically correct but since first sequence isn't, that isn't the answer.
It is not D because it doesn't multiply correctly at #12. Second sequence is supposed to start at 4 and not 0.

what is the mean,median,mode ,and range of 24,12,10,15,10,22,12
Answer:
24, 12, 10, 15, 10, 22, 12
mean: 7
median: 12
mode: 12
Range: 14
Step-by-step explanation:
Answer: Mean=15, Median=12, Mode=10 and 12, Range=14
Step-by-step explanation:
Data:
Numbers: 10, 10, 12, 12, 15, 22, 24
Mean: x, Median: x, Mode: x, Range: x
Step One, Find the Mean by adding all of the numbers and dividing them by the number of numbers
10+10+12+12+15+22+24=105/7=15
Mean=15
Reason: By adding all of the numbers together and dividing them by the number of numbers, you can find the mean because that is the method on finding the mean.
Step Two, Find the Median(middle) by finding the number in the middle
10, 10, 12, 12, 15, 22, 24
Median=12
Reason: Since the median is the number in the middle, 12 would be the median since it is the number in the middle of the array of numbers.
Step Three, Find the mode by finding the number that show up the most
10, 10, 12, 12, 15, 22, 24
Mode=10 and 12
Reason: Since mode is finding the number that shows up the most, 10 and 12 would be the answer for that reason and that they show up the same number of times in the array of numbers.
Step Four, Find the range by subtracting the biggest number by the smallest
24-10=14
Reason: Since to find the range you have to subtract the biggest number(24) by the smallest(10) the answer has to be 14 because that us the answer to 24-10.
I hope this helps!

Step-by-step explanation:
Perpendicular to x+y=6 and passing through (0,1)
Answer:
y = x + 1
Step-by-step explanation:
x + y = 6
y = -x + 6
Perpendicular slope to -1 is 1
(0,1)
y - y1 = m(x - x1)
y - 1 = 1(x - 0)
y - 1 = x
y = x + 1
Standard form:
y = x + 1
-x + y = 1
