Ms.Clark goes to the store and purchased a 26 lb turkey for $38.74 and two bags of potatoes. Her bill was $50.24. How much was each bag of potatoes? Write and solves the equations.
Answer:
$5.75
Step-by-step explanation:
50.24 - 38.74 is 11.5
Then, to find how much each potato bag is you need to divide by 2.
11.5 divided by 2 is 5.75.
Each bag of potatoes was 5.75$

What is the slope of the line that goes through the points (-1,4) and (14,-2)?
Answer:
hi! so we have 2 points right? you will need to use something called the slope formula y2-y1/x2-x1 we're subtracting our y values of both points and x values of both points while dividing them this gives us a slope of a line
now I want you to label before you do this in your head! it can get confusing to think about it so label label (x1-1,y1 4) (x2 14,y2 -2) now you have them labeled this parts easy! use the formula -2-4/14--1 okay now use your calculator you get -2/5 and now you have your m or slope!
memorize y2-y1/x2-x1 now! it will save you!

Exponential function f(x) passes through the points (3,6) and (7,18) determine the value of F(20)To the nearest integer
Answer:
A generic exponential function can be written as:
f(x) = A*e^(b*x)
Where A and b are real numbers, that we need to find.
We know that the points (3, 6) and (7, 18) are solutions to the equation, then we have that:
A*e^(b*3) = 6
A*e^(b*7) = 18
This is a system of equations, to solve this we can take the quotient between the two equations, so we remove the variable A.
(A*e^(b*7))/(A*e^(b*3)) = 18/6
e^(b*7)/e^(b*3) = 3
e^(b*7 - b*3) = 3
e^(4*b) = 3
Now we can apply the Ln(x) to both sides, because:
Ln(e^y) = y
then:
Ln(e^(4*b)) = Ln(3)
4*b = Ln(3)
b = Ln(3)/4
Then we have:
f(x) = A*e^(Ln(3)/4*x)
And we can use one of the equations to find the value of A. for example:
6 = A*e^(Ln(3)/4*3)
6/e^(Ln(3)/4*3) = 2.632
Then the exponential function is:
f(x) = 2.632*e^(Ln(3)/4*x)
Then we have that:
f(20) = 2.632*e^(Ln(3)/4*20) = 639.576
Rounding to the next integer, we have:
f(20) = 640
An exponential function can represent growth or decay.
The value of f(20) is 673
An exponential function is represented as:
[tex]y = ab^x[/tex]
At point (3,6), we have:
[tex]6 = ab^3[/tex]
At point (7,18), we have:
[tex]18 = ab^7[/tex]
Divide both equations
[tex]\frac{18}{6}= \frac{ab^7}{ab^3}[/tex]
[tex]3= b^4[/tex]
Take 4th roots of both sides
[tex]\sqrt[4]{3}= b[/tex]
Rewrite as:
[tex]b = \sqrt[4]{3}[/tex]
[tex]b = 1.32[/tex]
Substitute 1.32 for b in [tex]6 = ab^3[/tex]
[tex]a(1.32)^3 = 6[/tex]
[tex]2.30a = 6[/tex]
Divide both sides by 2.3
[tex]a = 2.61[/tex]
So, the function is:
[tex]y =2.61(1.32)^x[/tex]
When x = 20, we have:
[tex]y =2.61(1.32)^{20[/tex]
[tex]y =673[/tex]
Rewrite as:
[tex]f(20)=673[/tex]
Hence, the value of f(20) is 673

Lucas wants to write 3 ÷ 2 as a mixed number. He performs the division below. 3 ÷ 2 = 1 R1 Explain how to write the quotient as a mixed number. Drag the words to complete the explanation. Words may be used once or not at all. quotientdivisordividendremainder Use the whole number part of the as the whole number part of the mixed number. Write the in the numerator of the fraction and write the in the denominator of the fraction.
Answer:
1 1/2
Step-by-step explanation:
Given the improper fraction 3÷2, this can also be written as 3/2.
Writing as a mixed fraction means writing as a combination of a whole number and fraction e.g a b/c
a is the whole number
b/c is the fraction
3/2 = 1.5
1.5 = 1 + 0.5
1+0.5 = 1 + 5/10
3/2 = 1 + 1/2
Hence 3÷2 expressed as mixed fraction is 1 1/2
The mixed number representation of 3 ÷ 2 is 1 1/2.
To write the quotient of 3 ÷ 2 as a mixed number, we use the whole number part of the quotient as the whole number part of the mixed number.
We write the remainder (1) in the numerator of the fraction, and the divisor (2) in the denominator of the fraction.
As, the whole number part of the quotient is the number of times the divisor (2) can be divided into the dividend (3) evenly.
In this case, 2 can go into 3 once, with a remainder of 1.
To express this as a mixed number, we write 1 as the whole number part, and the remainder (1) as the numerator of the fraction. The divisor (2) is written in the denominator of the fraction.
Therefore, the mixed number representation of 3 ÷ 2 is 1 1/2.

Answer:

Step-by-step explanation:
Test the hypothesis using the P-value approach. Be sure to verify the requirements of the test. Upper H 0: pequals0.6 versus Upper H 1: pgreater than0.6 nequals200; xequals135, alphaequals0.05 Is np 0 (1 minus p 0 )greater than or equals10.
Use technology to find the P-Value.
Answer:
Step-by-step explanation:
From the given information:
The null and the alternative hypothesis can be well written as:
[tex]H_o:P=0.6[/tex]
[tex]H_1:P>0.6[/tex]
Given that:
n = 200
x = 135
Alpha ∝ = 0.05 level of significance
Then;
⇒ [tex]n \times p\times (1-P)[/tex]
= 200 × 0.6 × (1 -0.6)
= 200 × 0.6 × 0.4
= 48 ≥ 10
The sample proportion [tex]\hat P = \dfrac{x}{n}[/tex]
[tex]= \dfrac{135}{200}[/tex]
= 0.675
The test statistics [tex]Z = \dfrac{\hat P - P}{\sqrt{ \dfrac{P(1-P)}{n} }}[/tex]
[tex]Z = \dfrac{0.675 - 0.6}{\sqrt{ \dfrac{0.6 \times 0.4}{200} }}[/tex]
[tex]Z = \dfrac{0.075}{\sqrt{ \dfrac{0.24}{200} }}[/tex]
Z = 2.165
The P-value = P(Z > 2.165)
= 1 - P(Z < 2.165)
From the z tables
= 1 - 0.9848
= 0.0152
Reject the null hypothesis since P-Value is lesser than alpha. ( i.e. 0.0152 < 0.05).
Thus, there is enough evidence to conclude that the value of the population proportion is greater than 0.6

Evaluate D57C-76CA in base 16
c₁₆ - a₁₆ = 12 - 10 = 2₁₆
7 < c = 12 in base 16, so borrow 1 from the next place value:
17₁₆ - c₁₆ = 23 - 12 = 11 = b₁₆
In the next place, we replace 5 with 4, but 4 < 6, so borrow 1 from the next place value again:
14₁₆ - 6₁₆ = 20 - 6 = 14 = e₁₆
Replace d with c, so that
c₁₆ - 7₁₆ = 12 - 7 = 5₁₆
and this gives
d57c₁₆ - 76ca₁₆ = 5eb2₁₆

Explanation:
The most you could do with this is use the quadratic formula on

to get

So you could factor using Complex values:

Your firm is contemplating the purchase of a new $570,000 computer-based order entry system. The system will be depreciated straight-line to zero over its five-year life. It will be worth $58,000 at the end of that time. You will save $270,000 before taxes per year in order processing costs, and you will be able to reduce working capital by $73,000 (this is a one-time reduction). If the tax rate is 35 percent, what is the IRR for this project? (Do not round intermediate calculations and enter your answer as a percent rounded to 2 decimal places, e.G., 32.16.)
Answer:
IRR = 31.93%
Step-by-step explanation:
Depreciation = 570,000/5 = 114,000
Calculation of Operating cash flow
Operating income = 270000 - 114000 = 156,000
Tax = 156,000 * 35% = 54,600
Operating cash flow = Operating income + Depreciation - Tax = 156,000 + 114,000 - 54,600 = 215,400
Calculation of initial investment
CF0 = Initial investment - Working capital = 570,000 - 73,000 = 497,000
Calculation of the last year cash flow
CF5 = OCF + After tax salvage - Net working capital = 215,400 + 37,000 - 73,000 = 180,100
Calculation of IRR
IRR for the project = IRR(Cashflow from year0, 1, 2,3,4,5) "as attached below picture below"
IRR for the project = 31.93%

She buys packages of 12 trading cards to add to her collection. After she adds 16 packages to her existing collection, she has a total of 274 cards.
Write a function to model the size of Sabrina’s collection.
Enter the correct equation in the box.
Answer:
x + (12x16) = 274
Step-by-step explanation:
each package = 12
16 packages
16x12= 192
x + 192 = 274
274-192=82
x = 82
The function to model the size of Sabrina’s collection is x + (12× 16) = 274.
What is Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given:
Total cards = cards
Each package = 12
let the size of Sabrina collection be x
Then, x + (12× 16) = 274
x + 192 = 274
x = 274- 192
x= 82
Hence, the function to model the size of Sabrina’s collection is x + (12× 16) = 274.
