6.) A kennel owner has 168 feet of fencing with which
to enclose a rectangular region. He wants to subdivide
this region into three smaller rectangles of equal
length. If the total area to be enclosed 832 ft-, what are
the possible dimensions of the region?
Answer:
The possible dimensions of the region are
52 ft by 16 ft
32 ft by 26 ft
Step-by-step explanation:
Let
x -----> the length of the rectangular region
y ----> the width of the rectangular region
we know that
The perimeter of a rectangle is equal to
[tex]P=2(x+y)[/tex]
Remember that
A kennel owner wants to subdivide this region into three smaller rectangles of equal length
so
we also have to take into account the divisions
[tex]P=2(x+y)+2y[/tex]
[tex]P=2(x+2y)[/tex]
we have
[tex]P=168\ ft[/tex]
[tex]168=2(x+2y)[/tex]
simplify
[tex]84=(x+2y)[/tex] -----> [tex]x=84-2y[/tex] -----> equation A
The total area to be enclosed is 832 ft^2
The area is equal to
[tex]A=xy[/tex]
so
[tex]832=xy[/tex] ----> equation B
substitute equation A in equation B
[tex]832=(84-2y)y[/tex]
[tex]832=84y-2y^2[/tex]
[tex]2y^2-84y+832=0[/tex]
Solve the quadratic equation by graphing
The solution are y1=16 ft, y2=26 ft
see the attached figure
For
[tex]y=16\ ft\\x=84-2(16)=52\ ft[/tex]
For
[tex]y=26\ ft\\x=84-2(26)=32\ ft[/tex]
therefore
The possible dimensions of the region are
52 ft by 16 ft
32 ft by 26 ft
A cardboard box, which weighs 0.6 pounds empty, is filled with 15 bags of beans and a 4-pound bag of rice. the total weight of the box and the contents inside it is 25.6 pounds. One way to represent this situation is with the equation 0.6+15b+4=25.6 . In this situation, what does the solution to the equation represent?
Answer:
the weight of a bag of beans
Step-by-step explanation:
You have an equation representing the total weight of a box, 15 bags of beans, and a bag of rice. You want to know the meaning of the variable b in the equation ...
0.6 +15b +4 = 25.6
Sum of weightsEach term in the equation is the weight of something.
The first term (0.6) is the weight of the empty box.
The second term (15b) is the weight of 15 bags of beans. In this context, we assume the meaning of 'b' is the weight of 1 bag of beans.
The third term (4) is the weight of a bag of rice.
The term on the right of the equal sign (25.6) is the total of the other weights.
SolutionThe unknown value in the equation is the value of 'b', the weight of a bag of rice. When we solve for that value, we get ...
4.6 +15b = 25.6
15b = 21
b = 21/15 = 7/5 = 1.4
When this value is multiplied by bags, the result is pounds. That means the units of 'b' are "pounds per bag", the weight of one bag of rice.
The solution (b=1.4) represents the weight of one bag of rice.
The solution to the given equation represents the weight of one bag of beans. The variable 'b' represents this weight in the equation, and by solving, we can find this value.
Explanation:The equation 0.6+15b+4=25.6 represents a situation where a cardboard box, which is empty weighs 0.6 pounds, is filled with 15 bags of beans and a 4-pound bag of rice, leading to a total weight of 25.6 pounds. Here, the variable 'b' represents the weight of one bag of beans. To find this value, we rearrange the equation and isolate 'b', leading to the equation b=(25.6-0.6-4)/15. We then calculate the righthand side to get the weight of a bag of beans. The solution to the equation is the weight of one bag of beans.

Average annual rainfall totals for cities in New York are listed below.
Rochester 0.97 meters
Ithaca 0.947 meters
Saratoga Springs 1.5 meters
New York City 1.268 meters
a. Put the rainfall measurements in order from least to greatest. Write the smallest total rainfall in word form and expanded form.
b. Round each of the rainfall totals to the nearest tenth.
c. Imagine New York City’s rainfall is the same every year. How much rain would fall in 100 years?
d. Write an equation using an exponent that would express the 100-year total rainfall. Explain how the digits have shifted position and why.
Answer:
a) Order: 0.947 < 0.97 < 1.268 < 1.5
b)Smallest total rainfall = 0.947 meters in Ithaca
c) 100 years total rainfall = [tex]126.8 \text{ meters} = 1.268\times 10^2[/tex]
Step-by-step explanation:
We are given the following data in the question:
City: Rochester Ithaca Sara-Toga New-York
Rainfall(meters): 0.97 0.947 1.5 1.268
a) Order:
0.947 < 0.97 < 1.268 < 1.5
Ithaca < Rochester < New-York < Sara-Toga
Smallest total rainfall = 0.947 meters in Ithaca
Expanded form: [tex]0.947 = 9\times \frac{1}{10} + 4\times\frac{1}{100} + 7\times \frac{1}{1000}[/tex]
Word form: seven thousandths and ninety four hundredths.
b) Round off to nearest tenths
Rochester - 1.0 meters
Ithaca - 0.9 meters
Sara-Toga - 1.5 meters
New-York - 1.3 meters
c) [tex]\text{Rainfall in 100 years} = \text{Annual rainfall}\times 100 = 1.268\times 100 = 126.8 \text{ meters}[/tex]
d) 100 years total rainfall = [tex]126.8\text{ meters} = 1.268\times 10^2 = 0.1268\times 10^3[/tex]
The points shifted because we have to multiply 1.268 by 100. This would again result in shifting the point towards right.
Final answer:
The rainfall totals ordered from least to greatest are Ithaca, Rochester, New York City, Saratoga Springs. Rounded to the nearest tenth, New York City would receive 126.8 meters of rain in 100 years, represented as 1.268 x 10^2 with the base ten exponent indicating multiplication by 100.
Explanation:
Ordering Rainfall Totals and Mathematical Operations
To answer the student's question regarding the average annual rainfall totals for cities in New York:
Ordering from least to greatest: Ithaca (0.947 meters), Rochester (0.97 meters), New York City (1.268 meters), Saratoga Springs (1.5 meters). The smallest total rainfall (Ithaca) in word form is nine hundred forty-seven thousandths and in expanded form is 0.9 + 0.04 + 0.007.
Rounding to the nearest tenth: Rochester (1.0 meters), Ithaca (0.9 meters), New York City (1.3 meters), Saratoga Springs (1.5 meters).
Rainfall in 100 years: New York City's rainfall of 1.268 meters every year would result in 126.8 meters of rain in 100 years.
Equation with exponent: The equation to express the total 100-year rainfall for New York City is 1.268 meters x 100 years. Using an exponent, this is written as 1.268 x 102. The digits shift two places to the left because the base ten exponent indicates the value should be multiplied by 100.
The figures above are based on the provided data and standard mathematical operations such as ordering, rounding, and multiplication with exponents.

In the figure shown, line AB is parallel to line CD.
Part A: What is the measure of angle x? Show your work. (5 points)
Part B: Explain how you found the measure of angle x by identifying the angle relationships that you used along the transversal. (5 points)
Answer:
we know that
By alternate interior angles
m∠PRD=m∠APR -------> equation
m∠PRD=120°
so
m∠APR=120°
m∠APR=m∠APQ+m∠QPR ---------> equation
m∠APQ=62°
m∠QPR=x°
Substitute the values in the equation 120=62+x
x=120-62
x=53
therefore
the answer is
The measure of angle x is equal to 53 degrees
Because the lines are parallel the lower outside angle given as 155 is equal to the opposite angle, which is made up of X and 62.
To find X subtract 62 from 115:
X = 115 - 62
X = 53

Babatunde has a mass of 78kg. What would Babatunde weigh on the Moon? (The gravitational field strength on the Moon is 1.6N/kg.)
Answer:
Babatunde weigh on the Moon would be 124.8 N
Step-by-step explanation:
* The wight of an object on the earth is mg , where m is the the
mass of the object in kg and g is the acceleration of gravity which
is 9.8 m/s²
* The mass of an object on earth is the same as the mass of the
same object on the moon but the weight of the object on the
earth is different from the weight of the same object on the
moon because the gravity on the earth different from on the moon
* The wight on the moon is mg , where m is the the mass of the
object in kg and g is gravitational field strength on the Moon
which is 1.6 N/kg
∵ Babatunde has a mass of 78 kg
∵ The mass on the moon = the mass on the earth
∵ On the moon the gravitational field strength is 1.6N/kg
∵ Weight = mg
∴ Babatunde weigh = 78 × 1.6 = 124.8 N
* Babatunde weigh on the Moon would be 124.8 N
Babatunde's weight on the Moon is calculated by multiplying his mass (78 kg) by the Moon's gravitational field strength (1.6 N/kg), resulting in 124.8 newtons.
Explanation:Calculating Babatunde's Weight on the MoonTo calculate Babatunde's weight on the Moon, we use the formula for weight, which is the product of mass and gravitational field strength. On Earth, the average acceleration due to gravity is approximately 9.8 m/s², and on the Moon, it is about 1.6 N/kg. Babatunde's mass on Earth is 78 kg. Therefore, to calculate his weight on the Moon, we multiply his mass by the Moon's gravitational field strength.
Weight on the Moon = Mass × Gravitational field strength on the Moon
Weight on the Moon = 78 kg × 1.6 N/kg
Weight on the Moon = 124.8 N
Babatunde would weigh 124.8 newtons on the surface of the Moon, significantly less than his weight on Earth due to the Moon's lower gravitational pull.
