there are 13 items in a bakers dozen. If Natalie orders 9 bakers dozen of muffins, how many muffins did Matslie order?
Natalie ordered a total of 117 muffins.
Explanation:A bakers dozen is equal to 13 items. If Natalie orders 9 bakers dozen of muffins, we can calculate the total number of muffins by multiplying 13 by 9.
Number of muffins = 13 * 9 = 117
Therefore, Natalie ordered 117 muffins.

Dave's sister baked $3$ dozen pies of which a third contained chocolate, a quarter contained marshmallows, a sixth contained cayenne, and one twelfth contained salted soy nuts. What is the smallest possible number of pies that had none of these ingredients?
Step-by-step explanation:
As Dave's sister baked 3 dozen pies.
So, total number of pies = 3 × 12 = 36
Number of pies = 3×12 = 36
Pies which contained chocolate = 1/3×36 = 12
Pies which contained marshmallows = 1/4×36 = 9
Pies which contained cayenne = 1/6×36 = 6
Pies contained soy nut = 1/12×36 = 3
So,
Pies that had none of these ingredients = 36 - (12+9+6+3)
= 36 - 30
= 6 pies
So, total 6 pieces are left that had none of these ingredients.
i.e. 1, 2, 3, 4, 5, 6
Therefore,
The largest possible number of pies that had none of thees ingredients = 6 piecesThe smallest possible number of pies that had none of thees ingredients = 1 pieceKeywords: smallest possible number

She baked 36 pies. Of these
1/3*36=12 contained chocolate
1/4*36=9 contained marshmallows
1/636=6 contained cayenne
1/12*36=3 contained salted soy nuts.
In order to make the number of pies with none of these ingredients as small as possible, Dave's sister should put all of these ingredients in different pies so that only one of the ingredients is in any pie. If she does this, then 12+9+6+3=30 of the pies will have one of these ingredients. The other 6 pies will have none of these ingredients. At least 6 pies have none of these ingredients.

What is the equation of the line that passes through the point (-1, -3) and has a slope of -5?
answers y = -5x -16
y = -5x -8
y = -5x +8
y = -5x + 16
Answer:
y = -5x -8
Explanation:
Find b in equation y = mx + b
Insert numbers to find b
-3 = -5· -1 + b
Step 1: Simplify both sides of the equation.
−3=(−5)(−1)+b
−3=5+b
−3=b+5
Step 2: Flip the equation.
b+5=−3
Step 3: Subtract 5 from both sides.
b+5−5=−3−5
b=−8
Insert into equation
y = -5x - 8

SUBMIT
Answer:
The periodic interest rate is 1.62 %
Step-by-step explanation:
Given:
Annual percentage rate = 19.66%
Time period = 30 days
To Find:
Periodic interest rate =?
Solution:
The periodic interest rate r is calculated using the following formula:
r = (1 + \frac{i}{m})^{\frac{m}{n}} - 1
Where,
i = nominal annual rate
n = number of payments per year i.e., 12 for monthly payment, 1 for yearly payment and so on.
m = number of compounding periods per year
The period interest rate per payment is integral to the calculation of annuity instruments including loans and investments.
Now substituting the values we get
[tex]r = (1 + \frac{19.66}{12})^{\frac{12}{12}} - 1[/tex]
[tex]r = (1 + \frac{19.66}{12})^1 - 1[/tex]
r = (1 +1.638 ) - 1
r = (2.638 ) - 1
r = 1.638 %

The area of a square is 144 square centimeters. Find the length of the diagonal. Write your answer in simplest radical form.
Answer:
[tex]12\sqrt{2}\ cm[/tex]
Step-by-step explanation:
step 1
Find the length side of the square
we know that
The area of a square is equal to
[tex]A=b^{2}[/tex]
where
b is the length side
we have
[tex]A=144\ cm^2[/tex]
substitute in the formula of area
[tex]144=b^{2}[/tex]
solve for b
square root both sides
[tex]b=12\ cm[/tex]
step 2
Find the length of the diagonal
Applying the Pythagorean Theorem
[tex]d^2=b^2+b^2[/tex]
see the attached figure to better understand the problem
substitute the given values
[tex]d^2=12^2+12^2[/tex]
[tex]d^2=288[/tex]
square root both sides
[tex]d=\sqrt{288}\ cm[/tex]

The 3rd term of a geometric sequence is -2 and the 7th is -32. Find the common ratio,the first term, the explicit formula, and the 10th term.
Answer:
see explanation
Step-by-step explanation:
The n th term of a geometric sequence is
[tex]a_{n}[/tex] = a[tex](r)^{n-1}[/tex]
where a is the first term and r the common ratio
Both a and r have to be found
Given a₃ = - 2, then
ar² = - 2 → (1)
Given a₇ = - 32, then
a[tex]r^{6}[/tex] = - 32 → (2)
Divide (2) by (1)
[tex]\frac{ar^6}{ar^2}[/tex] = [tex]\frac{-32}{-2}[/tex], that is
[tex]r^{4}[/tex] = 16 ( take the fourth root of both sides )
r = 2 ← common ratio
Substitute r = 2 into (1)
a × 2² = - 2, that is
4a = - 2 ( divide both sides by 4 )
a = - [tex]\frac{1}{2}[/tex] ← first term
Hence
[tex]a_{n}[/tex] = - [tex]\frac{1}{2}[/tex][tex](2)^{n-1}[/tex] ← explicit formula
and
[tex]a_{10}[/tex] = - [tex]\frac{1}{2}[/tex] × [tex]2^{9}[/tex] = - 0.5 × 512 = - 256
[tex](1 \times 10^{5)(6 \times {10}{4} [/tex]
Note that [tex]10^a\cdot10^b=10^{a+b}[/tex] or more general form, [tex]a^b\cdot a^c=a^{b+c}[/tex].
[tex]10^5\cdot6\cdot10^4=\boxed{6\cdot10^9}[/tex]

hab juice to all other juices. If 40 beings were surveyed altogether,
what percent of them preferred hab juice?
(step by step)
Answer:
30% of them preferred hab juice.
Step-by-step explanation:
Given:
A survey of all beings on planet Tott found that 12 beings preferred hab juice to all other juices.
40 beings were surveyed altogether.
Now, to find percent of them preferred hab juice.
Total beings surveyed = 40.
Number of beings preferred hab juice = 12.

How do you graph x-y-3=0
Answer:
see explanation
Step-by-step explanation:
To graph the line, we require 2 points
Find the intercepts, that is where the graph crosses the x and y axes
To find the x- intercept let y = 0 in the equation and solve for x
x - 3 = 0 ( add 3 to both sides )
x = 3 ⇒ (3, 0 ) ← x- intercept
To find the y- intercept let x = 0 in the equation and solve for y
- y - 3 = 0 ( add 3 to both sides )
- y = 3 ( multiply both sides by - 1 )
y = - 3 ⇒ (0, - 3 ) ← y- intercept
Plot the points (3, 0) and (0, - 3) and draw a straight line through them

Answer: [tex]QR=4.04[/tex]
Step-by-step explanation:

[tex]tan\alpha=\frac{opposite}{adjacent}[/tex]
In this case, given the right triangle PQR, you can identify that:
[tex]\alpha=60\°\\opposite=PR=7.0\\adjacent=QR[/tex]
Then, the next step is to substitute those values into [tex]tan\alpha=\frac{opposite}{adjacent}[/tex]:
[tex]tan(60\°)=\frac{7.0}{QR}[/tex]
And the final step is to solve for "QR" in order to find its value.

Your second mortgage of $31,200 is at a rate of 10.7% compounded quarterly for 8 years. What total will you have paid for your second mortgage after 8 years?
Answer:
The Amount paid after 8 years is $72611.76
Step-by-step explanation:
Given as :
The principal mortgage = p = $31,200
The rate of interest = r = 10.7% compounded quarterly
The time period of mortgage = t = 8 years
Let The Amount paid after 8 years = $A
Now, According to question
From Compounded Interest method
Amount = Principal × [tex](1+\dfrac{\textrm rate}{4\times 100})^{\textrm 4\times time}[/tex]
Or, A = p × [tex](1+\dfrac{\textrm r}{4\times 100})^{\textrm 4\times t}[/tex]
Or, A = $31,200 × [tex](1+\dfrac{\textrm 10.7}{4\times 100})^{\textrm 4\times 8}[/tex]
Or, A = $31,200 × [tex](1.02675)^{32}[/tex]
Or, A = $31,200 × 2.3273
∴ A = $72611.76
So, The Amount paid after 8 years = A = $72611.76
Hence, The Amount paid after 8 years is $72611.76 Answer

Answer:
$431.36 is budgeted for rent.
Step-by-step explanation:
Given:
Madison’s monthly salary is $1348.
Her budget for rent is 32% of salary.
Now, to find the amount budgeted for rent.

7 + 7 = 3x - 2x
14 = x
x = 14
12y + 1 + 3x - 7 = 180 {co interior angles}
12y + 1 + 3 * 14 - 7 = 180
12y + 1 + 42 - 7 = 180
12y + 36 = 180
12y = 180 - 36
12y = 144

Step-by-step explanation:
we have

This is a vertical parabola open downward
The vertex is a maximum
Find the vertex
step 1
Factor the leading coefficient -4

step 2
Complete the square
[tex]-4(x^{2}-2x+1-1)-25[/tex]
step 3
[tex]-4(x^{2}-2x+1)-25+4[/tex]
[tex]-4(x^{2}-2x+1)-21[/tex]
step 4
Rewrite as perfect squares
[tex]-4(x-1)^{2}-21[/tex]
the vertex is the point (1,-21)
so
The maximum value of the quadratic equation is (1,-21)
therefore
Marla didn't use the right steps to complete the square. Maria made a mistake in step 1, she put 8x instead of -2x
Marla correctly completed the square for the expression −4x2+8x−25, arriving at the simplified form −4(x+4)2 + 39 to find the minimum value.
Explanation:To find the minimum value of the quadratic expression −4x2+8x−25, Marla completed the square. Her steps are as follows:
Factor out the coefficient of x2: −4(x2+∼2x−∼) -25Add and subtract (b/2a)2 inside the parentheses: −4(x2+8x+16−16) −25Combine the added 16 with the −4 outside and subtract from −25: −4(x2+8x+16) + 64 −25Factor the perfect square trinomial and simplify: −4(x+4)2 + 39
Marla used the correct steps to complete the square, which simplifies to −4(x+4)2 + 39.
