Question:

A customer buys bouquets of tulips and bouquets of roses for $40.25. The bouquet contained 17 tulips and cost $18.25. What is the price of a bouquet of roses?

Answer:

[tex]Rose =\$22.00[/tex]

Step-by-step explanation:

Given

[tex]Total = \$40.25[/tex]

[tex]Tulips = \$18.25[/tex]

Required

The cost of a bouquet of roses

Since the customer bought a bouquet each, the formula to use is:

[tex]Total = Tulip + Rose[/tex]

Make Rose the subject

[tex]Rose =Total - Tulip[/tex]

[tex]Rose =\$40.25 - \$18.25[/tex]

[tex]Rose =\$22.00[/tex]

A bouquet of rose costs $22.00

Answer:

A. V = ⅓(½×3×4)9

Step-by-step explanation:

Volume of triangular pyramid = ⅓(Base area)height

Base area = ½×b×h

b = 3 cm

h = 4 cm

Base area = ½×3×4

Height of prism = 9 cm

Plug in the values

Volume = ⅓(½×3×4)9

Answer: With $17.50 you can buy 7 packs of grape tomatoes.

Step-by-step explanation: For this question you can find the answer by taking 52.50 ÷ 21 which is 2.5 so that packs are $2.50 a pack and then you can either plug in numbers or take 17.50 ÷ 2.5.

Hope this helps.

Answer:

You can only buy 7 packages. Each package cost $2.50

Step-by-step explanation:

Alright so the cost of 21 packages of grapes cost $52.50 dollars.

So to get how much 1 package cost you divide 21 into 52.50

so 52.50 divided by 21= 2.5

So each package cost $2.50

So you have $17.50 to spend

so take 2.50 and divided that by 17.50

17.50 divided by 2.5= 7 so you can only by 7 packages for $17.50

Answer:

4

Step-by-step explanation:

set

[tex]f(x,y)=x+y\\[/tex]

constrain:

[tex]g(x,y)=x^2+y^2 = 7\\h(x,y)=x^3+y^3=10[/tex]

Partial derivatives:

[tex]f_{x}=1\\f_{y} =1 \\g_{x}=2x \\g_{y}=2y\\h_{x}=3x^2 \\h_{y}=3y^2[/tex]

Lagrange multiplier:

[tex]grad(f)=a*grad(g)+b*grad(h)\\[/tex]

[tex]\left[\begin{array}{ccc}1\\1\end{array}\right]=a\left[\begin{array}{ccc}2x\\2y\end{array}\right]+b\left[\begin{array}{ccc}3x^2\\3y^2\end{array}\right][/tex]

4 equations:

[tex]1=2ax+3bx^2\\1=2ay+3by^2\\x^2+y^2=7\\x^3+y^3=10[/tex]

By solving:

[tex]a=4/9\\b=-2/27\\x+y=4[/tex]

Second mathod:

Solve for x^2+y^2 = 7, x^3+y^3=10 first:

[tex]x=\frac{1}{2} -\frac{\sqrt{13}}{2} \ or \ y=\frac{1}{2} +\frac{\sqrt{13}}{2} \\x=\frac{1}{2} +\frac{\sqrt{13}}{2} \ or \ y=\frac{1}{2} -\frac{\sqrt{13}}{2} \\x+y=-5\ or\ 1 \or\ 4[/tex]

The maximum is 4

Answer:

The total cost of meal is $65.34

Step-by-step explanation:

Price of the meal = $54

Sales tax on meal = 6%

Tip given= 15% on pre-tax amount

We need to find total cost of meal.

First finding sales tax amount:

We need to calculate 6% of 54



So, the sales tax would be $3.24

Now, we need to find tip amount

We will find 15% of 54



So, the tip given would be $8.1

The total cost of meal = Price of meal + Sales Tax + Tip

                                      = 54+3.24+8.1

                                      = 65.34

So, the total cost of meal is $65.34

Answer:

The difference in elevation between Laguna del Carbon and El Alto is 12,656 feet.

Step-by-step explanation:

Given that Laguna del carbon, a salt lake located in Argentina, lies 344 feet below sea level, while El Alto, Bolivia, is located approximately 13,000 feet above sea level, to determine what is the difference in elevation between Laguna del Carbon and El Alto, the following calculation must be performed:

13,000 - 344 = X

12.656 = X

Thus, the difference in elevation between Laguna del Carbon and El Alto is 12,656 feet.

The unknown dimension is 35

Step-by-step explanation:

The perimeter of a rectangle is l+l+w+w or 2l+2w (l=length, w=width)

[tex]l+l+w+w=84[/tex]

[tex]7+7+w+w=84[/tex]

[tex]14+w+w=84[/tex]

then we subtract 14 from 84

[tex]w+w=70[/tex]

[tex]2w=70[/tex]

[tex]\frac{70}{2}=35[/tex]

[tex]w=35[/tex]

Let's check our answer

[tex]35+35+7+7=84[/tex]

Answer and Step-by-step explanation:

This requires the use of the Sine trig function to solve for x.

The Sine trig function is as follows:

sin(θ) = [tex]\frac{Opposite Side}{Hypotenuse}[/tex]

Plug in the values and solve for x.

sin(60) = [tex]\frac{x}{24\sqrt{3}}[/tex]

Multiply each side by [tex]24\sqrt{3}[/tex]

[tex]24\sqrt{3} (sin(60)) = x\\\\\\\\36 = x[/tex]

36 is equal to x.
