Answer:

Step-by-step explanation:

Let x be the number of simple arrangements and y be the number of grand arrangements.

1. The florist makes at least twice as many of the simple arrangements as the grand arrangements, so

[tex]x\ge 2y[/tex]

2. A florist can make a grand arrangement in 18 minutes [tex]=\dfrac{3}{10}[/tex] hour, then he can make y arrangements in [tex]\dfrac{3}{10}y[/tex] hours.

A florist can make  a simple arrangement in 10 minutes [tex]=\dfrac{1}{6}[/tex] hour, so he can make x arrangements in [tex]\dfrac{1}{6}x[/tex] hours.

The florist can work only 40 hours per week, then

[tex]\dfrac{3}{10}y+\dfrac{1}{6}x\le 40[/tex]

3. The profit on the simple arrangement is $10, then the profit on x simple arrangements is $10x.

The profit on the grand arrangement is $25, then the profit on y grand arrangements is $25y.

Total profit: $(10x+25y)

Plot first two inequalities and find the point where the profit is maximum. This point is point of intersection of lines [tex]x=2y[/tex] and [tex]\dfrac{3}{10}y+\dfrac{1}{6}x=40[/tex]

But this point has not integer coordinates. The nearest point with two integer coordinates is (126,63), then the maximum profit is

[tex]\$(10\cdot 126+25\cdot 63)=\$2,835[/tex]

To maximize profit, the florist should produce 1 grand arrangement and 2 simple arrangements. The maximum profit is $45.

To maximize profit, the florist should produce a combination of grand and simple arrangements. Let's assume the florist makes x grand arrangements and at least twice as many simple arrangements, which would be 2x or more. Given that the florist can work only a total of 40 hours per week, we can set up the following equation:

18x + 10(2x) ≤ 40

Now, we solve for x to find the number of grand arrangements.

Simplifying the equation, we have 18x + 20x ≤ 40

Combining like terms, we get 38x ≤ 40

Dividing both sides by 38, we find that x ≤ 1.05

Since we can't have a fraction of an arrangement, the florist should produce 1 grand arrangement. From the given information, we know that the florist must produce at least twice as many simple arrangements as grand arrangements. Therefore, the florist should produce at least 2 * 1 = 2 simple arrangements.

The florist's maximum profit can be calculated by multiplying the profit per arrangement by the number of corresponding arrangements.

The profit for the grand arrangement is $25, so the total grand arrangement profit is 1 * $25 = $25. The profit for the simple arrangement is $10, so the total simple arrangement profit is 2 * $10 = $20. Therefore, the maximum profit is $25 + $20 = $45.

Answer: 43

Step-by-step explanation:

You have to use P.E.M. D.A.S. (Parentheses, Exponents, multiplication, division, addition, and subtraction.)

Starting with parentheses, 3+2= 6

Moving onto exponents, 6 squared is thirty six. Square roots, being the opposite of squares, are also done here. The square root of 49 is 7.

Now you add. 36 +7

The answer should be 43, unless I’m mistaken.

Answer:

41

Step-by-step explanation:

1. Look at the first digit and ask yourself: is this divisible by 8? (3 is not so you look at the next one)

2. 8 goes into 32 evenly 4 times (put 4 at the top)

3. Subtract 42

4. Drag down the 8

5. Does 8 go into 8? (Yes!)

6. Put one at the top and subtract to get zero

7. Answer is at the top: 41

Answer:

Nothing goes into 3

8 goes into 32  four times (8 times 4= 32) so that means you'd put 4 on top of 2

then you bring down the 8 and 8 goes into 8 once. (8 times 1= 8) so you'd put 1 on top of 8.

Now down below you'd put 32 below 32 since you subtract it.

I'm not sure what the 3 bottom ones are.

I think you'd put 8 in the first  boxes then 0 cause 8=8 = 0.

Answer:

The simplest form of the expression is 3² ⇒ 3rd answer

Step-by-step explanation:

- The expression is 3 power 3 multiplied by 3 power 3 over 3 power 4

∵ 3 power 3 = 3³

∵ multiplied by 3 power 3 = × 3³

∵ over 3 power 4 = ÷ [tex]3^{4}[/tex]

- Lets write all of them in one expression

∴ The expression = [tex]\frac{3^{3}*3^{3}}{3^{4}}[/tex]

- All the numbers in the expression is 3 to the power

∴ The expression have the same base 3

- Remember: if we have numbers of same base multiplied then we

 add their powers and if divided then we subtract their powers

 [tex]\frac{a^{m}*a^{n}}{a^{q}}=a^{m+n-q}[/tex]

- Lets use this rule to simplify the expression

Step-by-step explanation:I got the answer right :)

The dimensions of matrix B must be 3x1 to satisfy the given matrix multiplication where a 2x3 matrix A is multiplied by B to result in a 2x1 matrix C.

The student is asking about the dimensions of a matrix B that when multiplied by a given 2x3 matrix A, results in a 2x1 matrix C. In matrix multiplication, the product of an mxn matrix A and an nxp matrix B yields an mxp matrix C. The resulting matrix, C, has the same number of rows as the first matrix (A) and the same number of columns as the second matrix (B). Additionally, the number of columns in the first matrix must match the number of rows in the second matrix. Therefore, since matrix A has 3 columns, matrix B must have 3 rows for the multiplication to be defined. And since matrix C has 1 column, matrix B must have 1 column as well. So, the dimensions of matrix B are 3x1.

Final answer:

To find the radius of the circle, we can use the properties of a right triangle to solve for GH. GH is approximately 10.39cm.

Explanation:

To find the radius of the circle, we can start by observing that the angle GHJ is 15°, and the side GK is 6cm. Since GK is a radius of the circle and it is perpendicular to JH, we can conclude that JH is a diameter of the circle. So, the length of JH is twice the length of GK, which is 12cm.

Now, we can use the properties of a right triangle to find the radius of the circle. We have a right triangle GHJ, where GH is the radius of the circle and JH is the hypotenuse. Using the Pythagorean theorem, we can solve for GH:

GH^2 + GK^2 = JH^2

GH^2 + 6^2 = 12^2

GH^2 + 36 = 144

GH^2 = 108

GH = sqrt(108)

GH ≈ 10.39cm

The radius of the circle is approximately 10.39cm.

Answer:

Choice C, -1

Step-by-step explanation:

The trick here is to look at this as a pattern.

[tex]\sqrt{-1}[/tex] is i to the 1st power.

[tex]-1[/tex] is i to the 2nd power.

[tex]-\sqrt{-1}[/tex] is i to the 3rd power.

[tex]1[/tex] is i to the 4th power.

So what we do to solve something like this is divide the power by 4, and see how far away the number is from the pattern.

In other words, we divide, and our remainder is how many powers to count up to (a remainder of 0 is the 4th power).

So 34/4 = 8 with a remainder of 2. Therefore, it's i to the 2nd power, which is -1.

Answer:worked 7 hours

Step-by-step explanation:

93 - 65 = 28

28/4 = 7 hours

Michelle worked for 7 hours on the weekend night based on the equation 4h + $65 = $93, where h represents the number of hours worked.

Let's denote the number of hours Michelle worked as "h". She earned $4 per hour for her work, so the total amount she earned from her hourly wage is 4h. Additionally, she earned $65 in tips.

So, the total amount she made can be represented by the equation:

Total earnings = Hourly wage + Tips

$93 = 4h + $65

Now, we can solve for the number of hours Michelle worked:

4h + $65 = $93

Subtract $65 from both sides:

4h = $93 - $65

4h = $28

Now, divide both sides by 4 to solve for "h":

h = $28 / 4

h = 7

Michelle worked for 7 hours on that weekend night.

Answer:

m∠MHJ = 50°

========================

Step-by-step explanation:

Best explanation is as shown in the attached figure.

As shown in the figure:

x + 15 = 2x - 20  ⇒ vertex angles are congruent

solve for x ⇒ ∴ x = 35°

So, ∠MHJ =  2x - 20 = 2*35 - 20 = 50°

========================================

The measure of all angles will be:

∠MHJ = 2X - 20° = 2 * 35 - 20 = 50°

∠JHK = 180° - ∠MHJ = 180 - 50 = 130°

∠KHL = X + 15° = 35° + 15° = 50°

The container with a volume of 2 cubic yards, which is equivalent to 54 cubic feet, would require 3 barrels of sand to fill it up, as the volume of each barrel is 18 cubic feet.

To find out how many barrels of sand will be needed to fill a container with a volume of 2 cubic yards, we first need to convert cubic yards to cubic feet, as the measurement of the barrel volume is given in cubic feet. Since 1 cubic yard is equivalent to 27 cubic feet, 2 cubic yards will be 2 * 27 = 54 cubic feet.

Next, we divide the volume of the container by the volume of one barrel of sand. Hence, the number of barrels needed = 54 cubic feet / 18 cubic feet per barrel = 3 barrels.

So, it will take 3 barrels of sand to fill a container with a volume of 2 cubic yards.

Answer:

They bought 0 ticket of closest section and 7 tickets of other section

Step-by-step explanation:

- Callie and Madison went to buy concert tickets for themselves and

  their five friends

- That mean they are 7

- Tickets for the closest section were $45 each

- Tickets for other section were $30 each

- They  ended up spending a total of $210

- Assume that they buy x tickets for closest section and y tickets for

 the other section

∵ They want 7 tickets

∴ x + y = 7 ⇒ (1)

∵ The cost of the closest section ticket was $45

∵ The cost of the other section ticket was $30

∵ They spent $210 on them

∴ 45x + 30y = 210

- All terms have common factor 15, then divide them by 15

∴ 3x + 2y = 14 ⇒ (2)

* Now we have a system of equations to solve

- Multiply equation (1) by -2 to eliminate y

∴ -2x - 2y = -14 ⇒ (3)

- Add equations (2) and (3)

∴ x = 0

- substitute the value of x in equation (1) to find y

∴ 0 + y = 7

∴ y = 7

∵ x represents the number of tickets of the closest section and y

  represents the number of tickets in the other section

∴ They bought 0 ticket of closest section and 7 tickets of other

Answer: W(n) = 92lb*1.06^n

and W(14) = 92lb*1.06^14 = 208lb

Step-by-step explanation:

We know that at the beginning the baby elephant weighs 92Lbs, and for each week it augments by a 6% (or 0.06 in decimals)

Then, at the end of the first week, the weight is:

92lb*1.06 = 97.52lb

at the end of the second week:

(92lb*1.06)*1.06 = 103.37lb

and so on, so you can see that the pattern is:

W(n) = 92lb*1.06^n

where n is the number of weeks after the birth

W(0) = 92lb

W(1) =  97.52lb

...

And we want to know the weight at the end of the 14th week, so we must find:

W(14) = 92lb*1.06^14 = 208lb
