A health food producer has 250 samples of a new snack to distribute in the mall the producer has to keep at least 50 samples for display in the health food store for the product launch how long will the samples last if consumers are taking the samples at a rate of 25 every hour
Final answer:
The 200 samples available for distribution will last for 8 hours at a consumption rate of 25 samples per hour.
Explanation:
The health food producer has 200 samples to distribute (250 total minus 50 for display), and if consumers take samples at a rate of 25 every hour, you would divide the 200 samples by the rate of 25 samples per hour to calculate how long the samples will last.
200 samples ÷ 25 samples/hour = 8 hours.
Therefore, the samples available for distribution at the mall will last for 8 hours before they run out, assuming the rate of consumption is constant at 25 samples per hour.

Using the Rational Root Theorem, what are all the rational roots of the polynomial f(x) = 20x4 + x3 + 8x2 + x – 12?
-4/5 and 3/4
-4/5 and -3/4
-1, -4/5, 3/4 and 1
-1. -4/5, -3/4 and 1
Answer:
Option 1 is correct.
Step-by-step explanation:
The given polynomial is
[tex]f(x)=20x^4+x^3+8x^2+x-12[/tex]
we have to find all the rational roots of the polynomial f(x)
The Rational Root Theorem states that the all possible roots of a polynomial are in the form of a rational number i.e in the form of [tex]\frac{p}{q}[/tex]
where p is a factor of constant term and q is the factor of coefficient of leading term.
In the given polynomial the constant is -12 and the leading coefficient is 20.
[tex]\text{All possible factor of -12 are }\pm1,\pm2, \pm3, \pm4,\pm6,\pm12[/tex]
[tex]\text{All possible factor of 20 are }\pm1,\pm2,\pm4,\pm5,\pm10,\pm20[/tex]
So, the all possible rational roots of the given polynomial are,
[tex]\pm1,\pm2, \pm3, \pm4,\pm6,\pm12,\pm\frac{1}{2},\pm\frac{3}{2},\pm\frac{1}{4},\pm\frac{3}{4},\pm\frac{1}{10},\pm\frac{1}{5},\pm\frac{3}{5},\pm\frac{3}{10},\pm\frac{2}{5},\pm\frac{6}{5},\pm\frac{1}{20},\pm\frac{3}{20},\pm\frac{4}{5},\pm\frac{12}{5}[/tex]
Now, the rational roots of polynomial satisfy the given polynomial
[tex]f(-\frac{4}{5})=20(-\frac{4}{5})^4+(-\frac{4}{5})^3+8(-\frac{4}{5})^2-\frac{4}{5}-12=\frac{256}{625}\times 20-\frac{64}{125}+\frac{128}{125}-\frac{4}{5}-12[/tex]
[tex]=\frac{1024}{125}-\frac{64}{125}+\frac{128}{25}-\frac{4}{5}-12[/tex]
[tex]=\frac{960}{125}+\frac{128}{25}-\frac{4}{5}-12=12-12=0[/tex]
Hence, rational root.
[tex]f(\frac{3}{4})=20(\frac{3}{4})^4+(\frac{3}{4})^3+8(\frac{3}{4})^2+\frac{3}{4}-12=\frac{405}{64}+\frac{27}{64}+\frac{9}{2}+\frac{3}{4}-12=0[/tex]
rational root
[tex]f(1)=20(1)^4+(1)^3+8(1)^2+1-12=20+1+8-11=18\neq 0[/tex]
not a rational root.
hence, option 1 is correct

Derrick’s parents are finalizing a budget for his college expenses. His first year of college will cost $8,000, and his expenses will increase by 12% each year. What is the amount they should budget for Derrick’s four-year college education, to the nearest dollar?
$38,235 is needed.
$42,823 is needed.
$32,072 is needed.
$39,200 is needed.
1st year = 8000
2nd year = 8000 * 1.12 = 8960
3rd year = 8960*1.12 = 10035.20
4th year = 10035.20 * 1.12 = 11239.42
8000 + 8960 + 10035.20 + 11239.42 = 38234.62 round to $38,235
Answer:
$38,235 is needed.
Step-by-step explanation:
Given,
The cost of first year of college is $ 8000 and it is increasing by 12 % each year,
So, His first year's cost = $ 8000,
Second year's cost = 12 % more than the first year's cost = 112 % of first year's cost = 112 % of 8000 = 1.12 × 8000 = $ 8960,
Third year's cost = 112 % of second year's cost = 112 % of 8960 = 1.12 × 8960 = $ 10035.2
Fourth year's cost = 112% of third year's cost = 1.12 × 10035.2 = $ 11239.424
Hence, Total cost for four-year college education = 8000 + 8960 + 10035.2 + 11239.424 = $ 38234.624 ≈ $ 38235
⇒ $38,235 is needed.

How is .8333 as a fraction 5/6?
The decimal 0.8333 is equivalent to the fraction 2/3.
To convert the decimal 0.8333 to a fraction, follow these steps:
Step 1: Let x be the decimal value:
x = 0.8333
Step 2: Multiply both sides of the equation by 10000 to remove the decimal:
10000x = 8333.3
Step 3: Subtract x from both sides of the equation:
10000x - x = 8333.3 - 0.8333
9999x = 8332.4667
Step 4: Divide both sides of the equation by 9999 to isolate x:
x = 8332.4667 / 9999
Divide both the numerator and the denominator by their greatest common divisor, which is 3333:
x = (8332.4667 ÷ 3333) / (9999 ÷ 3333)
x = (2.49995) / 3
Now, the fraction as a whole number over the denominator:
x = 2 / 3
Therefore, the fraction is 2/3.

If f(x) is a continuous function defined for all real numbers, f(–10) = –2, f(–8) = 5, and f(x) = 0 for one and only one value of x, then which of the following could be that x value?
–7
–9
0
2
The only value of x where f(x) = 0 can be determined by looking at the function's behavior near the x-axis and using the Intermediate Value Theorem. In this case, the potential x value is -9.
The one and only value of x where f(x) = 0 is the point of the function that intersects the x-axis. Since the function is continuous, it must cross the x-axis at this point due to the Intermediate Value Theorem.
To determine the possible value of x, we look at the given function values at x = -10 and x = -8 and identify where the function changes sign from negative to positive. The value of x where this sign change happens is the possible x value.
From the provided choices, the only value that would make this sign change possible is -9. Therefore, -9 could be the value of x where f(x) = 0.
A box contains 12 1/2 square feet of tiles and costs $40.21 what is the approximate price per square foot
The approximate cost per square foot for the tiles is $3.22 when rounded to the nearest cent.
To calculate the price per square foot of tiles, divide the total cost of the tiles by the total number of square feet. The total cost given is $40.21, and the total area is 12 1/2 square feet.
First, convert the mixed number to an improper fraction. 12 1/2 is the same as 25/2 square feet. Now, to find the cost per square foot, perform the following division:
Price per square foot = Total cost / Total area in square feet
Price per square foot = $40.21 / (25/2 square feet)
Multiply by the reciprocal:
Price per square foot = $40.21 / 1 x 2 / 25
Price per square foot = $40.21 x 2 / 25
Price per square foot = $80.42 / 25
Price per square foot = $3.2168
Therefore, the approximate cost per square foot for the tiles is $3.22 when rounded to the nearest cent.
The approximate price per square foot is $3.22.
To find the price per square foot, divide the total cost by the total square footage. In this case, the cost is $40.21 and the square footage is 12 1/2 square feet.
1. Cost per square foot = Total cost / Total square footage
2. Cost per square foot = $40.21 / 12.5 sq ft ≈ $3.22/sq ft
1. Convert 12 1/2 square feet to a decimal: 12.5 sq ft.
2. Divide the total cost by the total square footage: $40.21 / 12.5 sq ft ≈ $3.22/sq ft.
To calculate the cost per square foot, you need to divide the total cost by the total square footage. In this case, the total cost is $40.21, and the total square footage is 12 1/2 square feet. First, convert 12 1/2 square feet to a decimal, which is 12.5 sq ft. Then, divide the total cost by the total square footage:
Cost per square foot = $40.21 / 12.5 sq ft ≈ $3.22/sq ft.
Therefore, the approximate price per square foot is $3.22.

Carlene is selling T-shirts for a fundraiser. The T-shirts cost $20.50 each. To date, she has raised $700. Her goal is to raise more than $8,900. How many more T-shirts, x, does Carlene need to sell to reach her goal?
Carlene needs to sell 400 more T-shirts at $20.50 each to reach her goal of raising more than $8,900, after already raising $700.
The question asks us to determine how many more T-shirts, designated as x, Carlene needs to sell to reach her fundraising goal of more than $8,900, given that each T-shirt costs $20.50 and she has already raised $700. To solve for x, we can set up the following equation:
Total goal - Amount already raised = Amount still needed
$8,900 - $700 = $8,200
Next, we divide the amount still needed by the price per T-shirt to find out how many T-shirts need to be sold:
x = Amount still needed / Price per T-shirt
x = $8,200 / $20.50
x = 400
Carlene needs to sell 400 more T-shirts to reach her goal.
Y=(3/5)x -3 and 5y =3x-10 these lines are and the second question?
The given lines Y=(3/5)x -3 and 5y =3x-10 are examples of linear equations which, when solved, are found to be parallel due to their identical slope.
Explanation:The lines given in the question are in the format y = mx + b, where 'm' is the slope and 'b' is the y-intercept. The equations are Y=(3/5)x -3 and 5y =3x-10. By comparing the coefficients, the slope of the first line is 3/5 and the y-intercept is -3. For the second equation, we first need to convert it into the 'y = mx + b' form. Dividing every term by 5 gives us y = (3/5)x - 2. Therefore, the slope of the second line is also 3/5 and the y-intercept is -2. Since both lines have the same slope, they are parallel lines.

Today, the stalk is $452$ centimeters tall, and Alice observed that its height increases by $5\%$ every day. How tall was the plant $2$ weeks ago when she first noticed it growing? Express your answer as a decimal to the nearest tenth.
Answer:
Te plant was 228.29 centimeters tall.
Step-by-step explanation:
To find the size of the plant 14 days (2 weeks ago), we will use a formula called "exponential growth."
[tex]A=P(1+r)^{t}[/tex]
where
A=accumulated amount.
P=initial ammount
r=rate
t=elapsed time.
replacing the values we have
A=452 centimeters
P=variable to find
r=5% = 0.05
t=2 weeks= 14 days
So, we substitute the values in the equation
[tex]452=P(1+0.05)^{14}[/tex]
Then, we clear the variable P
[tex]P=\frac{452}{1.05^{14} }[/tex]
and perform the operations
[tex]P=\frac{452}{1.979931} =228.29centimeters[/tex]
