Answer:
Step-by-step explanation:
The first equation is the weights of the rabbit and the ferret together which is
r + f = 7.
The second equation puts the weight of the ferret in terms of the rabbit. If the ferret's weight is 2 pounds more than the rabbit, then
f = r + 2 (the word "is" means equals). Since we know what f is equal to, we will sub it into the first equation and solve for r:
r + (r + 2) = 7 and
2r + 2 = 7 and
2r = 5 so
r = 2.5 pounds.
A rabbit weights 2.5 pounds and the ferret weights 7 - 2.5 which is 4.5 pounds.
A family is purchasing 17 tickets for a downtown walking tour. Adult tickets are $10, child tickets are $7, and senior tickets are $8.50. The total
cost of the tickets is $141.50, and they are purchasing 2 more senior tickets than adult tickets.
Create and solve a system of linear equations to represent this situation. Then select the true statement.
А. The solution to this system is nonviable because it results in a fractional number of tickets.
B. The solution to this system is no viable because it results in a negative number of tickets.
C. The solution to this system is viable.
D. The solution to this system is nonviable because it results in a fractional amount of money.
Answer:
А. The solution to this system is nonviable because it results in a fractional number of tickets.
Step-by-step explanation:
Let x represent the number of adult tickets, y represent the number of child ticket and z represent the number of senior ticket.
Since the number of purchased ticket is 17, hence:
x + y + z = 17 (1)
The total cost of tickets is $141.50, hence:
10x + 7y + 8.5z = 141.5 (2)
they are purchasing 2 more senior tickets than adult tickets, therefore:
x = z + 2 (3)
Solving equation 1 2 and 3 simultaneously gives:
x =17/3, y = 23/3, z = 11/3
Therefore the solution to this system is nonviable because it results in a fractional number of tickets.
Answer:
А.The solution to this system is nonviable because it results in a fractional number of tickets

There are 15 students on the debate team. Of these, 3 are boys. Give the ratio of boys to girls on the debate team in simplest form.
Answer:
1/4
Step-by-step explanation:
15 - 3 = 12
3 : 12
1 : 4
In its most basic form, the debate team's male-to-female ratio is 1/4.
What is ratio?The ratio can be defined as the number that can be used to represent one quantity as a percentage of another. Only when the two numbers in a ratio have the same unit can they be compared. Ratios are used to compare two objects.
given, There are 15 students on the debate team. Of these, 3 are boys.
Since there are 3 boys out of 15
Thus,
Number of girl = 15 - 3
Number of girls = 12
Ratios compare two numbers, usually by dividing them. If you are comparing one data point (A) to another data point (B), your formula would be A/B. This means you are dividing information A by information B.
thus,
The ratio of boys to girls = 3/12
the Ratio of boys to girls = 1/4
therefore, the ratio of boys to girls on the debate team in simplest form is 1/4.

Answer:
your marked choice is correct: x = e
Step-by-step explanation:
For the line to go through the origin, the ratio of ln(x) to x at the point must equal the slope at the point.
The slope of ln(x) is 1/x, so we require ...
ln(x)/x = 1/x
ln(x) = 1 . . . . . . multiply by x
x = e . . . . . . . . take antilogs
Points W. X, and Y are collinear Point X is between points W X, and Y, are collinear point x is between w and y WX = 3y + 11, WY = 6y - 25, and XY = y + 12. Find WX, XY, and WY.
Answer:
[tex]WX = 83[/tex]
[tex]WY = 119[/tex]
[tex]XY = 36[/tex]
Step-by-step explanation:
Given
[tex]WX = 3y + 11\\WY = 6y - 25\\XY = y + 12[/tex]
Required
Determine the values of WX, XY and XY
Since X is between W and Y, we have:
[tex]WY = WX + XY[/tex]
[tex]6y - 25 = 3y + 11 + y + 12[/tex]
Collect Like Terms
[tex]6y - 3y - y = 25 + 11 + 12[/tex]
[tex]2y = 48[/tex]
Solve for y
[tex]y = 48/2[/tex]
[tex]y = 24[/tex]
Substitute 24 for y in
[tex]WX = 3y + 11\\WY = 6y - 25\\XY = y + 12[/tex]
[tex]WX = 3 * 24 + 11[/tex]
[tex]WX = 83[/tex]
[tex]WY = 6 * 24 - 25[/tex]
[tex]WY = 119[/tex]
[tex]XY = 24 + 12[/tex]

Tonya grew 2.25 more inches before her 9 year height was recorded. What is her height at age 9
written with the correct number of significant digits?
Answer:
Tanya's height at age of 9 is 53.75 inches
Step-by-step explanation:
Tonya's age (yr.) Tonya's height (in.)
3 36.8
4 40
5 41.25
6 45
7 48.0
8 51.5
Tanya's height at the age of 8 = 51.5
We are given that Tonya grew 2.25 more inches before her 9 year height was recorded.
So, Tanya's height at age of 9 = 51.5+2.25
Tanya's height at age of 9 =53.75 inches
Hence Tanya's height at age of 9 is 53.75 inches

is an example of measuring a continuous variable.
Answer:
True : It is an example of a continuous variable
Step-by-step explanation:
Numerical variables acn be classed as either being discrete or continuous based on whether the values in the data set are finite and countable or not.
Discrete variables are characterized by possessing a finite number of possible values which are countable and usually do not involve decimal numbers in between successive whole numbers.
On the other hand continuous variables are non finite and usually contains a lot of points in between possible whole numbers such as in the scenario above, the race time for the students take up any number within minutes, seconds and milliseconds. Hence, making the possible Numner of values impossible to predict or state.

There are 8 members on a board of directors. If they must form a subcommittee of 3 members, how many different subcommittees are possible
Answer:
56 possible different subcommittees
Step-by-step explanation:
This is a combination problem.
In combination probability, the formula is;
nCr = n!/((n - r)! × r!)
Now, out of the 8 members on the board of directors, they now want to form a subcommittee of 3 members.
Thus, the different subcommittees possible is given by;
8C3 = 8!/((8 - 3)! × (3!)) = 56
Thus, there are 56 possible different subcommittees
The length of a rectangle is increasing at a rate of 1 meter per day and the width is decreasing at a rate of 2 meters per day. When the length is 8 meters and the width is 18 meters, then how fast is the AREA changing?
Answer:
The area is changing at 2 m²/d.
Step-by-step explanation:
The area of a rectangle is given by:
[tex] A = l*w [/tex]
Where:
l is the length
w is the width
We have that the length is increasing at a rate:
[tex] \frac{dl}{dt} = 1 \frac{m}{d} [/tex]
And the width is decreasing at a rate:
[tex]\frac{dw}{dt} = -2 \frac{m}{d}[/tex]
The change in the rectangle's area is the following:
[tex] \frac{dA}{dt} = w\frac{dl}{dt} + l\frac{dw}{dt} [/tex]
When the length is 8 meters and the width is 18 meters we have:
[tex] \frac{dA}{dt} = 18 m*1\frac{m}{d} + 8 m(-2 \frac{m}{d}) [/tex]
[tex] \frac{dA}{dt} = 18 \frac{m^{2}}{d} - 16 \frac{m^{2}}{d} [/tex]
[tex] \frac{dA}{dt} = 2 \frac{m^{2}}{d} [/tex]
Therefore, the area is changing at 2 m² per day.
I hope it helps you!

Simplify the compound fractional expression.
(x-(x/y) / (y-(y/x)
Answer:
The simplified form of the compound fractional expression is [tex]\frac{x^2(y-1)}{y^2(x-1)}[/tex].
Step-by-step explanation:
Simplify the fraction as shown:
[tex]\dfrac{x-\frac{x}{y} }{y-\frac{y}{x} }[/tex]
Take the LCM.
[tex]\dfrac{\frac{xy-x}{y} }{\frac{xy-y}{x} }[/tex]
Simplify,
[tex]\frac{xy-x}{y} \times\frac{x}{xy-y}[/tex]
[tex]\frac{x^2(y-1)}{y^2(x-1)}[/tex]
Hence, the simplified form of the compound fractional expression is [tex]\frac{x^2(y-1)}{y^2(x-1)}[/tex].
