A customer buys bouquets of tulips and bouquets of roses for $.. What is the price of a bouquet of roses?
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

The creators of a new organic drain cleaner claim that it is more effective at reducing clogs over the long term than a general soap solution. An
Independent group recently tested the cleaner to determine whether the claims are true. Three hundred households participated and were
divided into three equal-sized groups. Half of each group was randomly chosen to use the new cleaner, and half was assigned the soap solution
The households in each group used their given method for a year. This table shows the number of households that reported a reduction in clogs
in each group

Factor the algebraic expression below in terms of a single trigonometric function.
sin 2x + sin x - 2 (2 points)
We know that sin (2x) = 2 sinxcosx.
So, sin (2x) + sin (x) - 2 becomes
2sin xcosx + sinx- 2.
Factor out sinx.
sinx(2cosx + 1 - 2)
sinx(2cosx - 1)

Step-by-step explanation:
Write an inequality of the form x > c or x < c to represent a constraint or condition in a real-world or mathematical problem. Recognize that inequalities of the form x > c or x < c have infinitely many solutions; represent solutions of such inequalities on number line diagrams.
Twenty rubber spheres were compressed with varying amounts of force. The widths and heights of the resulting shapes were measured. Here is a scatter plot that shows the measurements for each sphere.
The vertical axis of the scatter plot would be labeled vertical
in
.
Answer:
It would be on the side 0-12 so the Y axis
Step-by-step explanation:
Put Vertical Axis (In)
The vertical axis of the scatter plot is the height; on the other hand, if the sphere is 6 inches, the height is closer to 5 inches than to 11 inches.
What is graph?In mathematics, the graph of a function f is the set of ordered pairs, where {\displaystyle f(x)=y.} In the common case where x and f(x) are real numbers, these pairs are Cartesian coordinates of points in two-dimensional space and thus form a subset of this plane.
we know that the vertical axis is :
In this scatter plot, the horizontal axis is the width; however, we know the second variable is the height and this should be in the vertical axis.
we know that the height if the width is six inches:
Following the trend of the graph, it can be concluded the height if the width is six inches is approximately 5 rather than 11 inches.

Laguna del carbon, a salt lake located in. Argentina, lies 344 feet below sea level. El alto, Bolivia, is located approximately 13,000 feet above sea level. What is the difference in elevation Laguna del Carbon and El Alto?
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.
Answer:
The Lowest place above sea level in the Americans.

) At a certain college, students are allowed to choose between online and in-person learning. 70% of the students choose online learning and 30% choose to come to campus for in-person instruction. Assume that the probability that a person studying online will contract the coronavirus is .02 and the probability that a person attending class in-person contracts the virus is .35 . (a) What is the probability that a person attending this college (either online or in-person) will contract the virus
Answer:
Probability = 0.119
Step-by-step explanation:
P (Coronavirus) = P(Person online & corona) or P(Person offline & corona)

The Hu family goes out for lunch, and the price of the meal is $54. The sales tax on the meal is 7%, and the
family also leaves a 15% tip on the pre-tax amount. What is the total cost of the meal?
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

Find the greatest solution for x+y when x^2+y^2 = 7, x^3+y^3=10
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]
