222 gallons of milk containing 7% butterfat and 111 gallons of milk containing 4% butterfat must be used to obtain 333 gallons of milk containing 6% butterfat.
Let's assume that x gallons of milk containing 7% butterfat are needed, and y gallons of milk containing 4% butterfat are needed to obtain 333 gallons of milk containing 6% butterfat.
We can set up two equations to represent the given information:
Equation 1: x + y = 333
Equation 2: 0.07x + 0.04y = 0.06(333)
Simplifying Equation 2, we get:
0.07x + 0.04y = 19.98
Multiplying both sides of Equation 1 by 0.04, we get:
0.04x + 0.04y = 13.32
Subtracting this equation from Equation 2, we get:
0.03x = 6.66
Dividing both sides by 0.03, we get:
x = 222
Substituting x = 222 into Equation 1, we get:
222 + y = 333
y = 111
Therefore, 222 gallons of milk containing 7% butterfat and 111 gallons of milk containing 4% butterfat must be used to obtain 333 gallons of milk containing 6% butterfat.

Which of the following describes the graph of y--4x-38 compared to the parent square root function?
O stretched by a factor of 2, reflected over the x-axis, and translated 9 units right
O stretched by a factor of 2, reflected over the x-axis, and translated 9 units left
O stretched by a factor of 2, reflected over the y-axis, and translated 9 units right
O stretched by a factor of 2, reflected over the y-axis, and translated 9 units left
Answer:
There is no square root function mentioned to compare with, but assuming you meant the parent square root function y = sqrt(x), the correct answer is:
A.) "stretched by a factor of 2, reflected over the x-axis, and translated 9 units right"
To see this, note that the equation y = 4x + 38 can be rewritten as y - 38 = 4(x - (-9.5)). This means that the graph of y = 4x + 38 is a transformation of the parent function y = sqrt(x) as follows:
It is stretched vertically by a factor of 2 (since the coefficient of x is 4 instead of 1)It is reflected over the x-axis (since the coefficient of x is positive)It is translated 9 units to the right (since the vertex is at (-9.5, -38) instead of (0, 0))So the correct answer is (a) stretched by a factor of 2, reflected over the x-axis, and translated 9 units right.
Answer:
answer is (a) stretched by a factor of 2, reflected over the x-axis, and translated 9 units right.

Jenny has $1200 in her savings account. If the bank pays 3% interest per year on savings, how much interest does she earn in one year?
Answer:
To find out how much interest Jenny earns in one year, we can use the formula:
interest = principal x rate x time
where:
the principal is the amount of money in the savings account
rate is the interest rate per year, expressed as a decimal
time is the length of time the money is in the account, in years
In this case, Jenny's principal is $1200, the rate is 3% or 0.03 as a decimal, and the time is 1 year. Plugging these values into the formula, we get:
interest = 1200 x 0.03 x 1
interest = $36
Therefore, Jenny earns $36 in interest in one year.

How to determine the image of a figure by rigid transformations
Herein we find the representation of a triangle, whose vertices are described below:
A(x, y) = (5, 5), B(x, y) = (5, 6), C(x, y) = (7, 5)
Whose image must be determined by a rigid transformation known as translation:
P'(x, y) = P(x, y) + T(x, y)
Where:
P(x, y) - Original point.P'(x, y) - Image of the point.T(x, y) - Translation vector.Now we proceed to determine the images of the vertices of the triangle:
A'(x, y) = (5, 5) + (4, - 3)
A'(x, y) = (9, 2)
B'(x, y) = (5, 6) + (4, - 3)
B'(x, y) = (9, 3)

What is the smallest positive integer n such that the fourth root of 56*n*360 is an integer?
The smallest positive integer n that makes the fourth root of 56n360 an integer is n = 81.
We can start by simplifying the expression inside the fourth root:
56 * n * 360 = [tex]2^{3}[/tex] * 7 * n * [tex]2^{3}[/tex] * [tex]3^{2}[/tex] * 5
= [tex]2^{6}[/tex] * [tex]3^{2}[/tex] * 5 * 7 * n
Taking the fourth root of this expression gives:
[tex](56*n*360)^{(1/4)}[/tex] = [tex](2^{6}*3^{2}*5*7*n) ^{(1/4)}[/tex]
= [tex]2^{(6/4)}[/tex] * [tex]3^{(2/4)}[/tex] * [tex]5^{(1/4)}[/tex] * [tex]7^{(1/4)}[/tex] * [tex]n^{(1/4)}[/tex]
= 4 * [tex]3^{(1/2)}[/tex] * [tex]5^{(1/4)}[/tex] * [tex]7^{(1/4)}[/tex] * [tex]n^{(1/4)}[/tex]
For the fourth root to be an integer, [tex]n^{(1/4)}[/tex] must be an integer, and since we want n to be as small as possible, we want [tex]n^{(1/4)}[/tex] to be as small as possible.
The smallest possible value of n that makes [tex]n^{(1/4)}[/tex]an integer is when n is a fourth power of a prime number. Therefore, we can let n = [tex]p^{4}[/tex], where p is the smallest prime number that makes the expression under the fourth root an integer.
From the expression above, we can see that p must be a factor of 7 and [tex]35^{2}[/tex] in order to make the expression under the fourth root an integer. The smallest prime factor of 7 and [tex]35^{2}[/tex] is 3, so we can let p = 3. Then:
n = [tex]p^{4}[/tex] = [tex]3^{4}[/tex] = 81

An entrepreneur invests in a new play. The cost includes an overhead of $33,750 plus production costs of $1700 per performance. A sold-out performance brings in $2325 . Assume every performance is sold out, and let x represent the number of sold-out performances.
The entrepreneur's revenue is $2325x, entrepreneur's cost is $33,750 + $1700x and entrepreneur's profit from x sold-out performances is $625x - $33,750
The entrepreneur's revenue from x sold-out performances is given by the formula:
Revenue = (Price per Performance) x (Number of Performances)
Revenue = $2325 x x
Revenue = $2325x
The entrepreneur's cost from x sold-out performances is given by the formula:
Cost = Overhead + (Production Cost per Performance) x (Number of Performances)
Cost = $33,750 + $1700x
The entrepreneur's profit from x sold-out performances is the revenue minus the cost:

The distribution is roughly symmetric, we can use the mean as a measure of center and the standard deviation as a measure of spread.
The distribution of miles ran each week by Elisa is relatively symmetric and centered around 30 miles per week, with a relatively tight spread of about 2.3 miles per week.
We have,
a.
Since the distribution is roughly symmetric, we can use the mean as a measure of center and the standard deviation as a measure of spread.
However, the distribution also has some slight right-skewness, so we may want to consider using the median instead of the mean, depending on the context and purpose of the analysis.
b.
The mean of the distribution is:
= (28 + 29 + 30 + 31 + 32 + 33 + 34)/7
= 30.1
So the center of the distribution is around 30 miles per week.
The standard deviation of the distribution is approximately 2.3 miles per week, which tells us that the spread of the distribution is relatively tight.
Alternatively, we could use the median as a measure of the center.
Since there are 7 data points, the median is the average of the 4th and 5th values (30 and 31):
= (30 + 31)/2
= 30.5
So the center of the distribution is also around 30 miles per week using the median.
Thus,
The distribution is roughly symmetric, we can use the mean as a measure of center and the standard deviation as a measure of spread.
