Answer:

The maximum profit the florist will earn from selling celebration bouquets is $725.

The florist will break-even after one-dollar decreases when her profit is zero. From the graph, this occurs at x = 10. So the florist will break-even after 10 one-dollar decreases.

The interval of the number of one-dollar decreases for which the florist makes a profit from celebration bouquets is (0, 10). This is because the profit is positive for values of x between 0 and 10, and becomes negative after 10.

Answer:

The equation is 8 x 13 = 104

Answer:

(a) \(V = (-8W^3 + 800W^2)/3\)

(b) \(W > 100\)

Step-by-step explanation:

Let's call the length of the box L, the width W and the height H. Then, we can write the following equations:

"A rectangular box has a base that is 4 times as long as it is wide"

\(L = 4W\)

"The sum of the height and the girth of the box is 200 feet"

\(H + (2W + 2H) = 200\)

\(2W + 3H = 200 \rightarrow H = (200 - 2W)/3\)

The volume of the box is given by:

\(V = L * W * H\)

Using the L and H values from the equations above, we have:

\(V = 4W * W * (200 - 2W)/3\)

\(V = (-8W^3 + 800W^2)/3\)

The domain of V(W) is all positive values of W that gives a positive value for the volume (because a negative value for the volume or for the width doesn't make sense).

So to find where V(W) > 0, let's find first when V(W) = 0:

\((-8W^3 + 800W^2)/3 = 0\)

\(-8W^3 +800W^2 = 0\)

\(W^3 -100W^2 = 0\)

\(W^2(W -100) = 0\)

The volume is zero when W = 0 or W = 100.

For positive values of W ≤ 100, the term W^2 is positive, but the term (W - 100) is negative, then we would have a negative volume.

For positive values of W > 100, both terms W^2 and (W - 100) would be positive, giving a positive volume.

So the domain of V(W) is W > 100.

Answer: We can conclude that at least one of the population means has a different value than the other population means.

Step-by-step explanation:

When the null hypothesis is rejected for an analysis of variance, we can then conclude that at least one of the population proportions has a different value.

For one-way analysis of variance, it should be noted that the null hypothesis is rejected when there is sufficient evidence which is used in making the conclusion that not all the means are equal and that there is a different value.

Answer:

\(\frac{4}{5t}\)

Step-by-step explanation:

Quotient means division, and 5 times t is 5t, as we are simplifying. Since 4 comes first in the question or sentence, 4 must be the nominator; therefore, 5t is the denominator.

The answer would then be \(\frac{4}{5t}\).

The true statement about the axis of rotation is the option;

It is parallel to a side of the equilateral triangle, but is separate from the equilateral triangle.

The axis of rotation is a straight line around which all points on a rotating body rotates.

The diagram shows a figure with a hollow cylindrical cross section and triangular cross section on the left and right, which indicates that the figure is created by the rotation of the equilateral triangle about height of the cylinder, such that the axis of rotation is a vertical line through the center of the hollow cylinder. Therefore, the axis of rotation is parallel to the height of the cylinder, and therefore, it is parallel to the base of the equilateral triangle, but it it seperate from walls of the cylinder, and therefore, separate from the equilateral triangle

Remark

I take it the semicircles cover the full width of the paper.

So the radius is \(24\div2 = 12 \ \text{cm}\)

Since there are two of them, the area = a full circle.

Step One

Find the area of the rectangle before the cuts were made.

\(\text{Area = L} \times \text{W}\)

\(\text{L = 30}\)

\(\text{W = 24}\)

\(\text{Area} = 30 \times 24 = 720 \ \text{cm}^2\)

Step Two

Find the area of the circle cut outs.

\(\text{r} = 12\)

\(\text{Area} = \pi \times \text{r}^2\)

\(\text{Area} = 3.14 \times 12^2\)

\(\text{Area} = 3.14 \times 144\)

\(\text{Area} = 452.16 \ \text{cm}^2\)

Step Three

Find the total area left

\(\text{Total Area Left = rectangle - circle}\)

\(\text{Total Area Left} = 720 - 452.16\)

\(\text{Total Area left} = 267.84 \ \text{cm}^2\)   Answer

Answer: Half of them are even and half of them are odd.

Step-by-step explanation:

The even numbers are 6, 12, 18, 24, and 30. An even number is defined as a number that is divisible by 2, meaning it has no remainder when divided by 2. For example, 6 divided by 2 equals 3 with no remainder, so 6 is even.

The odd numbers are 3, 9, 15, 21, and 27. An odd number is defined as a number that is not divisible by 2, meaning it has a remainder of 1 when divided by 2. For example, 9 divided by 2 equals 4 with a remainder of 1, so 9 is odd.

Therefore, out of the given numbers, half of them are even and half of them are odd.

The Temperature was -9 degrees Fahrenheit when Patrick woke up.

Patrick went to sleep last night, the temperature was 2 degrees Fahrenheit. While he was sleeping, the temperature fell by 11 degrees Fahrenheit. To find the temperature when Patrick woke up, we need to subtract 11 from the initial temperature of 2.

Initial temperature: 2 degrees Fahrenheit

Change in temperature: -11 degrees Fahrenheit

To find the temperature when Patrick woke up, we subtract the change in temperature from the initial temperature:

Final temperature = Initial temperature + Change in temperature

Final temperature = 2 degrees Fahrenheit - 11 degrees Fahrenheit

Final temperature = -9 degrees Fahrenheit

Therefore, when Patrick woke up, the temperature was -9 degrees Fahrenheit.

  84° +(r +59)° +(r +51)° = 180°

  2r +194 = 180 . . . . . . . . . divide by ° and simplify

  2r = -14 . . . . . . . . . .  subtract 194

Answer:

(a) 275ft²

(b) 3 gallons

(c) $73.50

Step-by-step explanation:

(a)

The shape of the wall consists of a triangle and a rectangle, so to find the wall's area we find the area of the triangle and rectangle and add them together:

Area of triangle = 0.5*base*height = 0.5*22*5 = 55ft²

Area of rectangle = base*height = 22*10 = 220ft²

So the area of the wall = 55ft²+220ft²=275ft²

(b)

To find how many gallons it would take, you divide the area by the amount of are one gallon covers: 275 / 105 = 2.619

Rounded up, this is 3 gallons

(c)

Since we're buying 3 gallons and each costs $24.50, we multiply 3 by the price to find the total: 3*24.5 = $73.50

Answer:

A system of linear equations is a set of two or more equations containing two or more variables. The solution to a system of linear equations is the set of values for the variables that makes all the equations in the system true.

For example, a system of linear equations whose solution is (6,19) could be represented by the following equations:

x + 2y = 25

3x - 4y = 6

Solving this system would yield x = 6 and y = 19 as the solution.

It has taken me 32 minutes to drive 48 km. If the total length of my journey is 146 km and I maintain the same speed,  then you can estimate that you will be driving for approximately 65.344 minutes longer to complete the remaining 98 km of your journey.

To estimate how much longer you will be driving for, we can use the concept of proportionality. We know that the time taken to drive 48 km is 32 minutes. Let's use this information to find the time it would take to drive 146 km.

We can set up a proportion to find the time:

(time taken for 48 km) / (48 km) = (time taken for 146 km) / (146 km)

Let's solve for the time taken for 146 km:

(time taken for 146 km) = (time taken for 48 km) * (146 km / 48 km)

Substituting the given values:

(time taken for 146 km) = 32 minutes * (146 km / 48 km)

Calculating the value:

(time taken for 146 km) ≈ 32 minutes * 3.042

(time taken for 146 km) ≈ 97.344 minutes

Therefore, it would take approximately 97.344 minutes to drive 146 km at the same speed.

To estimate how much longer you will be driving for, we can subtract the initial time of 32 minutes from the estimated time of 97.344 minutes:

Additional time = 97.344 minutes - 32 minutes

Additional time ≈ 65.344 minutes
