Answer:
The owner needs 195 meters of wire
Step-by-step explanation:
If the lot is squared shaped, then its area is given by the formula:
[tex]Area =x^2[/tex]
where x is the side of the square. Then considering the value they provide for the surface, each side must be of length:
[tex]x^2=\frac{4225}{16} \,m^2\\x=\sqrt{\frac{4225}{16}} \,\,m\\x=16.25\,\,m[/tex]
Then the perimeter around this square lot is four times that side length:
Perimeter = 4 (16.25 m) = 65 m
and since the owner wants three rows of wire, the total length of wire needed is:
3 (65 m) = 195 m

Discussion Topic There are four basic operations: addition, subtraction, multiplication, and division. Do you think these four operations can be performed on polynomials? What would it look like to perform these operations on polynomials? Which operation do you think would be the simplest? Which do you think will be difficult?
Step-by-step explanation:
1. Yes addition, subtraction, multiplication, and division can be performed on polynomials. like our everyday arithmetic dealings with mathematical operators, polynomials are no exception when it comes to math operators, the four basic operations addition, subtraction, multiplication, and division can be performed on polynomials as well.
2. It can be less handy plus the operation can get messy if you do not have a good sense/understanding/hold of what you are doing things can get messy.
3. I personally know that the simplest is the addition of polynomials
4. I cant say which is difficult, but the operation that can get things messy for me most time is the division operation

Suppose $x-3$ and $y+3$ are multiples of $7$. What is the smallest positive integer, $n,$ for which $x^2+xy+y^2+n$ is a multiple of $7$? Enter your answer. I need Immediate help or you wont get the points.
In the language of modular arithmetic, we're given
[tex]x-3\equiv0\pmod7\implies x\equiv3\pmod7[/tex]
[tex]y+3\equiv0\pmod7\implies y\equiv-3\equiv4\pmod7[/tex]
Then x = 7a + 3 and y = 7b + 4 for integers a and b.
Substitute these into the quadratic expression and simplify:
[tex]x^2+xy+y^2+n\equiv0\pmod7[/tex]
[tex](7a+3)^2+(7a+3)(7b+4)+(7b+4)^2+n\equiv0\pmod7[/tex]
[tex]49a^2+42a+9+49ab+28a+21b+12+49b^2+56b+16+n \equiv 0\pmod7[/tex]
[tex]37+n\equiv 0\pmod7[/tex]
[tex]n\equiv-2\equiv5\pmod7[/tex]
which means the smallest positive integer n we are looking for is 5.
Are the terms CSC, SEC, and COT equivalent to the terms Sin^-1, Cos^-1, and Tan^-1? Are the three pairs of terms the same thing just written differently, or are they entirely different?
Answer:
Step-by-step explanation:
It depends on how it is written. By definition
[tex]\csc(x) = (\sin(x))^{-1} = \frac{1}{\sin(x)}[/tex]
[tex]\sec(x) = (\cos(x))^{-1} = \frac{1}{\cos(x)}[/tex]
[tex]\cot(x) = (\tan(x))^{-1} = \frac{1}{\tan(x)}[/tex]
however the functions
[tex]\sin^{-1}(x), \cos^{-1}(x), \tan^{-1}(x)[/tex] are the inverse functions of sine, cosine and tangent respectively. So, they are not equivalent functions
The following is the student's grades for a certain class
(left : grades, right : frequency)
determine :
a.) how many students have grades that are above than 73,5
b) how many students have grades that are below 75
Answer:
a) 20 students
b) 20 students
Step-by-step explanation:
a) From the given frequency table, we have to check the number of students that scored above 73.5 and add them up.
Therefore, the number of students that have grades above 73.5 are:
14 + 4 + 2 = 20 students
b) 75 falls in between 74 - 76 and we do not have the individual frequencies of the grades (74, 75, 76).
However, we can use the data we have from the table to make an assumption.
The number of students that have grades below 75 will be:
13 + 5 + 2 = 20 students
If y is inversely proportional to x and y = 5, when x = 7, find the value of y when x = 70
Answer:
y = [tex]\frac{1}{2}[/tex]
Step-by-step explanation:
Given y is inversely proportional to x then the equation relating them is
y = [tex]\frac{k}{x}[/tex] ← k is the constant of variation
To find k use the condition y = 5 when x = 7, then
5 = [tex]\frac{k}{7}[/tex] ( multiply both sides by 7 )
35 = k
y = [tex]\frac{35}{x}[/tex] ← equation of variation
When x = 70, then
y = [tex]\frac{35}{70}[/tex] = [tex]\frac{1}{2}[/tex]
(OFFERING ALL THE POINTS I HAVE) Word Problem. Please help!! Part 1 of problem: The main tank has a radius of 70 feet. What is the volume of the quarter-sphere sized tank? Round your answer to the nearest whole number and use 3.14 for Pi. (Use sphere volume formula) Part 2: The theme park company is building a scale model of the killer whale stadium main show tank for an investor's presentation. Each dimension will be made 6 times smaller to accommodate the mock-up in the presentation room. How many times smaller than the actual volume is the volume of the mock-up? Part 3: Using the information from part 2, answer the following question by filling in the blank: The volume of the actual tank is __% of the mock-up of the tank.
Answer:
Part 1: 359,007 ft³
Part 2: 216 times smaller
Part 3: 21600%
Step-by-step explanation:
Part 1:
The parameters for the tank are;
The radius of the tank = 70 feet
The volume of a sphere = 4/3·π·r³
Therefore, the volume of a quarter sphere = 1/4×The volume of a sphere
The volume of a quarter sphere = 1/4×4/3·π·r³ = π·r³/3
Plugging in the value for the radius gives
Volume = π×70³/3 = 114,333.33×3.14 = 359,006.7≈ 359,007 ft³.
Part 2:
The dimension of the scale model = 1/6 × Actual dimension
Therefore, we have the radius of the sphere of the scale model = 1/6 × 70
Which gives;
The radius of the sphere of the scale model = 35/3 = 11.67 feet
The volume of the scale model = π·r³/3 = (3.14×11.67³)/3 = 1662.07 ≈ 1662 ft³
The number of times smaller the scale model is than the actual volume = (Actual volume)/(Scale model) = (359,007 ft³)/(1662 ft³) = 216 times
The number of times smaller the scale model is than the actual volume = 216 times = (1/Scale of model)³ = (1/(1/6))³ = 6³.
Part 3:
The percentage of the mock-up, x, to the volume of the actual tank is given as follows
x/100 × 1662 = 359,007
∴ x = 216 × 100 = 21600%
The percentage of the mock-up, to the volume of the actual tank is 21600%.
Answer:
Part 1: 359,007 ft³
Part 2: 216 times smaller
Part 3: 21600%
Step-by-step explanation:
Part 1:
The parameters for the tank are;
The radius of the tank = 70 feet
The volume of a sphere = 4/3·π·r³
Therefore, the volume of a quarter sphere = 1/4×The volume of a sphere
The volume of a quarter sphere = 1/4×4/3·π·r³ = π·r³/3
Plugging in the value for the radius gives
Volume = π×70³/3 = 114,333.33×3.14 = 359,006.7≈ 359,007 ft³.
Part 2:
The dimension of the scale model = 1/6 × Actual dimension
Therefore, we have the radius of the sphere of the scale model = 1/6 × 70
Which gives;
The radius of the sphere of the scale model = 35/3 = 11.67 feet
The volume of the scale model = π·r³/3 = (3.14×11.67³)/3 = 1662.07 ≈ 1662 ft³
The number of times smaller the scale model is than the actual volume = (Actual volume)/(Scale model) = (359,007 ft³)/(1662 ft³) = 216 times
The number of times smaller the scale model is than the actual volume = 216 times = (1/Scale of model)³ = (1/(1/6))³ = 6³.
Part 3:
The percentage of the mock-up, x, to the volume of the actual tank is given as follows
x/100 × 1662 = 359,007
∴ x = 216 × 100 = 21600%
The percentage of the mock-up, to the volume of the actual tank is 21600%.

A cycling race is 17 miles long. The cyclists will begin at point S and ride a number of laps around a neighborhood block. After the last lap, the cyclists will sprint 2.0 miles to the finish line. A rectangle with a width of 0.75 miles and height of 0.5 miles. The 2 mile finish comes out of one corner. Using the equation w (1.5 + 1) + 2 = 17, the race's organizer determined the cyclists will need to ride 9 laps before the sprint to the finish. Which explains the error? The equation should be 0.75 w + 0.5 w + 2 = 17, and the cyclists will need to ride 12 laps before the sprint to the finish. The equation should be 2 (0.75 w + 0.5) + 2 = 17, and the cyclists will need to ride 21 laps before the sprint to the finish. The solution should be 6, and the cyclists will need to ride 6 laps before the sprint to the finish. The solution should be 8, and the cyclists will need to ride 8 laps before the sprint to the finish.

How many seconds will elapse between seeing lightning and hearing the thunder if the lightning strikes 5.0 mi (26,400 ft) away and the air temperature is 83.6°F?
Answer:
Time taken = 23.10 sec (Approx)
Step-by-step explanation:
Given:
Distance of lighting = 5 mi = 26,400 ft
Air temperature =83.6°F = 28.67°FC
Computation:
Speed of the sound
V = 331 + 0.61 × T
V = 331 + 0.6 × 28.67
V = 348.202 m/s
Distance = 5 mi = 8,046.72 m
Time taken = Distance / Speed
Time taken = 8,046.72 / 348.202
Time taken = 23.10 sec (Approx)

What is the value of log0.5^16
Answer:
-4.81647993062
Step-by-step explanation:
Look at the image below ↓
Based on the mathematical analysis, the value of log 0.5^16 is -4.816.
What are Logarithms?A logarithm is a mathematical term that is used to describe the exponent or power to which a base must be raised to yield a given number.
In this case, to calculate the value of log0.5^16 use logarithm properties.
rewrite the expression as log(0.5)^(16).
=> log(a^b) = b * log(a)
=> 16 * log(0.5).
Given that the Logarithm is the inverse of exponentiation => log(0.5) is equal to -0.301.
Substitute this value back into the expression:
16 * (-0.301) = -4.816.

Jack had 4 hours of school. He spent 45 minutes in the library and 12 hour on a science lecture and had a lunch break of 25 minutes. How much time is left for the school to get over? (Write the answer as a fraction.)
Answer:
[tex]\dfrac{10}{4} \ hour[/tex]
Step-by-step explanation:
Given that :
Jack had 4 hours of school.
He spent 45 minutes in the library
1/2 hour on a science lecture and;
had a lunch break of 25 minutes
The objective is to determine how much time is left for the school to get over and we are to write the answer as a fraction.
In order to do that, we will have to convert the minutes into hours,
we all know that; 60 minutes = 1 hour.
Then,
45 minutes = (45/60)hour = 3/4 hour
25/60 minutes = 1/4 hour
Therefore, the amount of time left for the school to get over is:
= [tex]4 - (\dfrac{3}{4}+\dfrac{1}{2}+ \dfrac{1}{4})[/tex]
= [tex]\dfrac{16-(3+2+1)}{4}[/tex]
= [tex]\dfrac{16-6}{4}[/tex]

A builder wrote the measurements needed for a door.
height of door
2032 mm
width or door
Why did the builder write these measurements using millimetres instead of cm or m?
Answer:
Check the answer below.
Step-by-step explanation:
This is a very trivial but professional question. Note that all of millimetre, centimetre and metres are acceptable metric units but the millimetre is more preferable by builders and architects because:
1. It is easier to work with integer values on building and architectural plans, an advantage given by measuring and recording in millimetre.
2. working in millimetre allows for precision. The builder will record values that are very close to the true value
3. The measurement will be easily readable by anybody that sees it.

The ratio of the measures of the acute angles of a right triangle is 8:1. In degrees, what is the measure of the largest angle of the triangle?
Answer:
80°
Step-by-step explanation:
The sum of the measures of the acute angles in a right triangle is 90°. The sum of ratio measures in the ratio 8 : 1 is (8+1) = 9. Thus, each of those measures stands for 90°/9 = 10°. Then the angle ratio is ...
80° : 10° = 8 : 1
The measure of the largest acute angle in the triangle is ...
10° × 8 = 80°
does the table represent a function why or why not?
Answer:
Yes, because each x-value corresponds to one y value.
Step-by-step explanation:
If you look at the table, you notice that there is one output (y) for every input (x). This means that it is a function. It would NOT be a function if you had two outputs for an input. For example, there are two x values that are 6. For one coordinate pair, the table says (6,9) and (6,8). Since there are two values for the same input- it wouldn't be a function. In this case, there is an input of 4 and 5 with the same output. That is okay! Even though they have the same y value, those inputs still only have ONE output.
5. Lisa sold costume jewelry at a bazaar. The
first hour she sold 2 bracelets and 3 rings
for a total of $26. Later a customer bought
2 rings and paid $12. All bracelets were
priced the same. All rings were priced the
same. How much did a bracelet cost?
Answer:
$4
Step-by-step explanation:
2 Bracelets + 3 rings = $26
2 rings = $12
3 rings = x
To get the cost of 1 ring you divide 12 by 2 and the answer you get is 6.
The total cost of the 3 rings is $18( $6*3)
Then you subtract the cost of both 2 bracelets and 3 rings($26) from the cost of 3 rings($18). The answer is $8. ( THIS IS THE COST OF 2 BRACELETS)
1 BRACELET= $4( $8/2)
