Miguel's mother sells houses. She wants to buy a piece of land on which to build several houses. there are two lots for sale. one is a rectangular plot that is 3/8 of a mile by 2/3 of a mile. the other is a square plot that is 2/5 of a mile by 2/5 of a mile.
Part A
Which lot should Miguel's mother buy if she wants the biggest lot?
Part B
If the land in the area sells for 750,000 a square mile, how much should she expect to pay?
Answer:
A) She should buy the
Step-by-step explanation:
Part A:
For question A, we find the areas of both plots and see which one is greater.
For the first one, we do 3/8 * 2/3
[tex]\frac{3}{8} * \frac{2}{3} = \frac{6}{24} = \frac{1}{4}[/tex]
The area of the first plot is 1/4 square miles
For the second one, we do 2/5 * 2/5
[tex]\frac{2}{5} *\frac{2}{5} = \frac{4}{25}[/tex]
The area of the second plot is 4/25 square miles
We have 1/4 and 4/25.
To see which one is bigger, we make them have the same denominator, also known as the LCM (Least Common Multiple).
LCM(4,25) = 100
Now we make 1/4 have a denominator of 100
4 times what is 100?
25, so the numerator is 25 and the denominator is 100.
We get: 25/100
Now we make 4/25 have a denominator of 100
25 times what is 100?
4, so the numerator is 4 * 4 = 16 and the denominator is 100.
We get: 16/100
Now we can see which is bigger:
25/100 or 16/100
25/100 is bigger
Therefore, Miguel's mother should buy the plot with dimensions 3/8 and 2/3.
Part B
For part B, I'm not sure which plot of land she is going to pay for, so I will answer both.
We answered this in Part A already.
The 3/8 and 2/3 plot was 1/4 square miles and the 2/5 by 2/5 plot was 4/25 square miles.
Plot 1:
1/4 square miles
It said that it costs $750,000 for a square mile
This plot is 1/4 square miles, so we do
[tex]$750,000 * \frac{1}{4} = \frac{750,000}{4} = 187,500[/tex]
The cost for plot 1 is $187,500
Plot 2:
4/25 square miles
It said that it costs $750,000 for a square mile
This plot is 4/25 square miles, so we do
[tex]750,000*\frac{4}{25} = \frac{3,000,000}{25} = 120,000[/tex]
The cost for plot 1 is $120,000
So for the 3/8 by 2/3 plot, it cost $187,500 and for the 2/5 by 2/5 plot costs $120,000

Find the length of side x in simplest radical form with a rational denominator.
Answer:
x = [tex]3\sqrt{2}[/tex]
Step-by-step explanation:
This is an isosceles triangle, so the missing side is also 3
x = [tex]\sqrt{3^2 + 3^2}[/tex]
= [tex]\sqrt{9+9}[/tex]
= [tex]\sqrt{18}[/tex]
Simplify [tex]\sqrt{18}[/tex]:
18 = 2 x 3 x 3
[tex]\sqrt{18}[/tex] = [tex]\sqrt{2 * 3 * 3}[/tex]
[tex]\sqrt{18}[/tex] = [tex]\sqrt{2 * 3^2}[/tex]
[tex]\sqrt{18}[/tex] = [tex]\sqrt{2} * \sqrt{3^2}[/tex]
[tex]\sqrt{18}[/tex] = [tex]3\sqrt{2}[/tex]

Maya’s watch shows a time of 1:30pm. At. 5:30pm, her watch shows the time as
5:42pm. How many minutes did her watch gain every hour after 1:30pm?
Answer:
3 min/hr gain from 1:30 p.m. to 5:30 (nominal)
Step-by-step explanation:
Subtract 5:30 from 5:42; the result is 0:12. The watch gained a total of 12 minutes over the four-hour period from 1:30 p.m. to 5:30 p.m., or 3 min/hr:
1:30-2:30: 3 MIN
2:30-3:30: 3 MIN
3:30-4:30: 3 min
4:30-5:30: 3 min Summing up 3 min plus 3 min plus 3 min plus 3 min gives us 12 min.
Decide whether f(x)=-3x+5x^3-6x^2+2 is a polynomial function if the function is a polynomial function write it in standard form and state its degree type and leading coefficient
Answer:
yes it is a polynomial
5x^3 - 6x^2 - 3x + 2
cubic polynomial
leading coefficient = 5
Step-by-step explanation:
The polynomial in standard form as 5x³-6x² -3x+2
and the polynomial is of degree 3 and the leading coefficient is 5.
What is Polynomial?An algebraic expression known as a polynomial requires that all of its exponents be whole numbers. Any polynomial must have variable exponents that are non-negative integers. Although a polynomial contains variables and constants, we are unable to divide a polynomial by a variable.
Example: The standard form of the polynomial 5 + 2x + x² is expressed.
We shall first determine the polynomial's degree before expressing it in standard form.
The degree of the provided polynomial is two. Write the phrase containing the polynomial's degree.
Given:
function is -3x+5x³-6x²+2
As, the polynomial contain coefficients and operations.
So, the given function is a polynomial.
Now, writing the polynomial in standard form as
f(x)=5x³-6x² -3x+2
The above polynomial is of degree 3 and the leading coefficient is 5.

Find the equation of the line perpendicular to [tex]-\frac{1}{2} x[/tex] and passing through the point (−6; 1).
⦿ Hi There! ⦿
Point-Slope form:
y-y1=m(x-x1)
y-1=m(x-(-6)
Perpendicular lines have slopes that are opposite reciprocals.
It means that if we have -1/2, we flop it over and make it positive.
So the slope of the new line is 2.
y-y1=m(x-x1)
y-1=2(x-(-6)
y-1=2(x+6)
y=1=2x+12
y=2x+12-1
y=2x+11

The table shows how an elevator 500 feet above the ground is descending at a steady rate.
A two column table with 5 rows. The first column, time in seconds (t), has the entries, 0, 5, 10, 15. The second column, Height in feet h(t), has the entries, 500, 475, 450, 425.
Which equation represents the height, h(t), of the elevator in feet, as a function of t, the number of seconds during which it has been descending?
h(t) = 5t + 500
h(t) = 5t – 500
h(t) = –5t + 500

Expression:
When x=5, the value of the expression is :
Answer:
[tex]\frac{x+4}{3}[/tex] ; 3
Step-by-step explanation:
In this question, we're being asked to write an equation using the word format. Let's find key words in the statement.
The sum of a number x and 4, all divided by 3.
Looking at the wording, we can conclude that we are adding x and 4, and dividing that by 3. So here's how the phrase would look as an expression.
[tex]\frac{1}{3}[/tex] (x+4) or [tex]\frac{x+4}{3}[/tex]
Now, there's another part to this problem. We must evaluate the value of the expression if x is given to be 5. So let's plug it into our equations.
(5)+4
3
[tex]\frac{9}{3}[/tex]
9/3 gives you 3, so your answer would be 3.

find 2 points on the line:
A( -1 , 0)
B( 0 , -1)
Put them in the equation and fine m & b:
0=m(-1)+b
-1=m(0)+b
so b= -1
and m= -1
so f(x) = -x-1
Answer:
-x - 1
Step-by-step explanation:
line is passing through (-1, 0) (0, -1)
m = (-1 - 0) / (0 - (-1) )
= -1 / 1
= -1
line equation = y - y1 = m (x - x1)
y - 0 = -1 (x - (-1) )
y = -1 (x + 1)
y = -x - 1
y = f(x)
