Answer:
You want to leave a 15% tip on a meal that cost $16.25.
First, convert the 15% to an actual number that can be used in a calculation. For percents,this is always done by simply dividing the percent (in this case 15%) by 100%.So, the conversational term "15%" becomes 15% / 100% = 0.15 in terms of a real mathematical number.
Second, you need to find out what 15% of your $16.25 meal cost is.This is always done by multiplying 0.15 by $16.25, or
0.15 x $16.25=$2.44.
So, the amount of tip you are going to leave is $2.44.
This makes the total cost of your meal (to write on your charge slip or other payment)
$16.25 + $2.44 = $18.69.
Answer:
$19.99
Step-by-step explanation:
16.25 + 3% tax + 20% tip
16.25 * 0.03 = .49
16.25 * .20 = 3.25
16.25 + .49 + 3.25 = $19.99
1.2,3,7.5,18.75, which formula can be used to describe the sequence
Answer:
[tex]a_{n}=1.2 \times(2.5)^{n-1}[/tex]
Step-by-step explanation:
If we observe the given sequence, we find that the ratio of two consecutive terms is the same. i.e.
[tex]\frac{3}{1.2}=2.5\\\\\frac{7.5}{3}=2.5\\\\ \frac{18.75}{7.5}=2.5[/tex]
Such a sequence in which the ratio of consecutive terms remain the same is know as Geometric Sequence. Following formula is used to represent a Geometric Sequence:
[tex]a_{n}=a_{1}\times(r)^{n-1}[/tex]
Here:
[tex]a_{n}[/tex] is the general term. Using the value of n =1,2,3 ... will give us the term of the sequence.
[tex]a_{1}[/tex] is the first term which is 1.2 in this case.
r represents the common ratio which is 2.5.
Using these values we get:
[tex]a_{n}=1.2 \times(2.5)^{n-1}[/tex]
This formula can be used to represent the given sequence.

A number plus twice its reciprocal is negative nineteen-thirds
Answer:
The number could be [tex]x=-6[/tex] or [tex]x=-1/3[/tex]
Step-by-step explanation:
Let
x-----> the number
Remember that
The reciprocal of a number is 1 divided by the number
we know that
[tex]x+2(\frac{1}{x})=-\frac{19}{3}[/tex]
Solve for x
Multiply by 3x both sides
[tex]3x^{2} +6=-19x\\ \\ 3x^{2}+19x+6=0[/tex]
Solve the quadratic equation by graphing
The solutions are [tex]x=-6, x=-1/3[/tex]
see the attached figure
Verify both solutions
For [tex]x=-6[/tex]
[tex]-6+2(-\frac{1}{6})=-\frac{19}{3}[/tex]
[tex]-\frac{19}{3}=-\frac{19}{3}[/tex] ----> is true
For [tex]x=-1/3[/tex]
[tex]-(1/3)+2(\frac{1}{(-1/3)})=-\frac{19}{3}[/tex]
[tex]-\frac{19}{3}=-\frac{19}{3}[/tex] ----> is true

b(1) = -2
b(n) = b(n-1)-7
Find the 3rd term in the sequence.
Answer:
b(3) = -16
Step-by-step explanation:
b(1) = -2
b(n) = b(n-1) - 7
so
b(2) = b(1) - 7 = -2 - 7 = -9
b(3) = b(2) - 7 = -9 - 7 = -16
TWENTY FIVE POINTS!!!! In Sparrowtown's wig shop, 1/2 of the wigs are blonde and 3/10 of the wigs are brunette. What fraction of the wigs are either blonde or brunette?
Answer:
8/10
Half of 10 is 5 so 5/10 are blonde + 3/10 are brunette so you get 8/10 but in its simplest form would be 4/5
Answer:
8/10
Step-by-step explanation:
we know it is 8/10 because half of ten is five and 5/10 are blonde, then we add 3/10 which are brunette so we therefore get 8/10 or 4/5 if we simplify it to its simplest form!

joey can paint a room in 2 hours and chelsea can paint the same room in 3 hours. if they work together how long would it take to paint the room
Answer:
[tex]1.2\ hours[/tex]
Step-by-step explanation:
we know that
Joey can paint a room in 2 hours
That means
Joey can paint the 100% of the room-------> 2 hours
so
In 1 hour ------> can paint 100%/2=50%
Chelsea can paint a room in 3 hours
That means
Chelsea can paint the 100% of the room-------> 3 hours
so
In 1 hour ------> can paint (100%/3)=33.33%
therefore
Joey and Chelsea in 1 hour can paint -----> 50%+33.33%=83.33%
by proportion
[tex]\frac{1}{83.33}\frac{hour}{\%} =\frac{x}{100}\frac{hour}{\%}\\ \\x=100/83.33\\ \\ x=1.2\ hours[/tex]
Your parents ask you to choose between two offers for an allowance.
The first offer is to receive one penny on the first day, 2 penny’s on the second day, 4 pennies on the third day, 8 pennies on the fourth day and so on. (365 days).
Second offer is to receive 10 dollars the first week, 20 dollars the second week, 30 dollars the third week, and so on, for the entire year (52 weeks).
Which offer should you choose to make more money?
Answer:
The pennies
Step-by-step explanation:
We can create a geometric equation for the pennies and an arithmetic equation for the dollars.
The format for a geometric equation is
[tex]y=a_1(\frac{1-r^n}{1-r} )[/tex]
If we plug in the values we already know we should get the equation.
[tex]y=2^x-1[/tex]
Now we can plug in the number of days in a year for [tex]x[/tex] to find how much money we get.
[tex]2^{365}=7.52*10^{109}[/tex]
Which is basically 752 with 107 zeros following it.
Then we can divide this number by 100 to find the number of dollars it is.
We get 752 with 105 zeros following it.
Now we can find the arithmetic equation for the dollars.
We can see that 10 dollars is being added every time.
Use the formula.
[tex]a_n=a_1+m(n-1)[/tex]
We can plug in.
[tex]a_n=10+10(n-1)[/tex]
Now we can substitute 52 for [tex]x[/tex] in the equation.
[tex]a_{52}=10+10(52-1)[/tex]
[tex]a_{52}=10+510 \\ \\a_{52}=520[/tex]
So you'll be getting 520 dollars at the end of the year, which is far less than the amount of money you get from the pennies.
A right triangle has an area of 120 square units, and a leg length of 24 units. What is the perimeter of the triangle, in units?
Answer:
60 square units.
Step-by-step explanation:
First, work out what the length of of the other leg is
[tex]120 \times 2 = 240 \: 240 \div \: 24 = 10[/tex]
Next, to work out the hypotenuse you add the squares of the legs.
[tex] {24}^{2} + 10 ^{2} = 676[/tex]
Then square root the answer from the previous calculation.
[tex] \sqrt{676} = 26[/tex]
And finally add the sides together.
26+24+10= 60 square units
The Pythagoras theorem states that the sum of two squares equals the squared of the longest side. Then the perimeter of the triangle is 60 units.
What is a right-angle triangle?It's a form of a triangle with one 90-degree angle that follows Pythagoras' theorem and can be solved using the trigonometry function.
A right triangle has an area of 120 square units and a leg length of 24 units.
Then the other length of the triangle will be
Area = 1/2 (b x h)
120 = 1/2 (24 h)
240 = 24h
h = 10
Then the third length of the triangle will be given by the Pythagoras theorem.
H² = b² + h²
H² = 24² + 10²
H² = 576 + 100
H² = 676
H = 26
Then the perimeter of the right-angle triangle will be
Perimeter = 10 + 24 + 26
Perimeter = 60 units

Answer:
16%
Step-by-step explanation:
What you need to do is add both 48 and 240 together. That gives you a total of 288 flowers. Now you need to divide 48 by 288 because that will give you your percentage. In this case, it's 16%.
Answer:
Here.
Step-by-step explanation:
You add the number of flowers together to get the total number- 48 + 240 is 288.
48 should be 16.66%, as 288 divided by 6 is 48.

11. The scale for a drawing of the tennis court is
1 centimeter = 2 meters. What is the area of
the actual tennis court?
Width
5.5 cm
- Length 10 cm
show steps
Answer:
I believe the correct answer would be 220 meters.
Step-by-step explanation:
If one centimeter equals 2 meters, then you would have to multiply the width (5.5 cm.) by 2 and the length (10 cm.) by 2. After you multiply those, you get 11 meters for the width and 20 meters for the length. You then multiply those by each other, so 11x20, and you get 220.
The actual length and width will be 20 meters and 11 meters. Then the area of the rectangle will be 220 square meters.
What is the area of the rectangle?Let L be the length and W be the width of the rectangle.
Then the area of the rectangle will be
Area of the rectangle = L×W units
The scale for a drawing of the tennis court is 1 centimeter = 2 meters. Then the area of the actual tennis court will be
Width = 5.5 cm
Length = 10 cm
Then the actual length and width will be
L = 10 x 2 = 20 meters
W = 5.5 x 2 = 11 meters
Then the area of the rectangle will be
A = 20 x 11
A = 220 square meters
