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.

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
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....Two friends have a total of 60 coins. If the first fried gives 1/4 of his coins to the second friend, they will have an equal number of coins. How many coins does the first friend have at the beginning?
Answer:
The first friend has 40 coins.
Step-by-step explanation:
The statement says that the two friend have a total of 60 coins, which can be expressed as:
x+y=60 (1), where:
x is the first friend
y is the second friend
Also, the statement says that if the first friend gives 1/4 of his coins to the second friend, they will have an equal number of coins which means that if you subtract 1/4 of the coins the first friend has this would be equal to the number of coins the second friend has now, which is:
x-1/4x=y+1/4x
x-1/4x-1/4x=y
y=x-2/4x
y=x-1/2x (2)
Next, you have replace (2) in (1) and solve for x:
x+x-1/2x=60
2x-1/2x=60
3/2x=60
x=60/(3/2)
x=(60*2)/(1*3)
x=120/3
x=40
Finally, you can replace the value of x in (2) in order to find the value of y:
y=40-1/2(40)
y=40-(20)
y=20
According to this, the answer is that the first friend has 40 coins.

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

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)

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.

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%
find the quotient.
