The greatest common factor of 4a(2) b and 6ab(3)
Answers
first, find the greatest common factor of ur coefficients 4 and 6.....and that is gonna be 2
as for ur variables and exponents....take the lowest ones
so both have an " a " and a " b " variable....the lowest a term is just " a "...and the lowest " b " term is b
so the GCF of these 2 terms are : 2ab
The greatest common factor of the expressions 4a^2b and 6ab^3 is 2ab.
The question seeks to determine the greatest common factor of the expressions 4a2b and 6ab3. To find this, one must look at the common factors of the numerical coefficients (4 and 6) and the variables raised to their respective powers (a2 and a, b and b3). The numerical common factor of 4 and 6 is 2. The lowest power of 'a' common to both terms is a1 and for 'b' is b1. On doing this we get 2ab.

2. Pat is six years older than twice his Cousin Zach’s age. The sum of their ages is less than 36.
What is the greatest age that Zach could be?
Answers
C = Cousin Zach
2C + 6 = P
2C + 6 - 6= P - 6
2C = P - 6
2C/2 = P - 6/2
C = P - 3
C + 3 = P
so (C + 3) + P < 36
(C + 3 - 3) + P < 36 - 3
C + P < 33
Can you see what I am doing?
We know the following facts:
1.Pat is six years older than twice his Cousin Zach’s age. We can rewrite this statement as:
P=2*Z+6
2. The sum of their ages is less than 36.
P+Z<36
In order to find the greatest age that Zach could be we should find for which Z
P+Z=35 (the first whole number smaller than 36)
P=35-Z
35-Z=2*Z+6
35-6=3Z
29=3Z
Z=29/3
Z=9

Good Luck :)
Final answer:
To write 230,000 in standard form, place the decimal point after the first non-zero digit. For 230,000, the standard form is 2.3 x 10⁵.
Explanation:
To express the number 230,000 in standard form, you simply write it as it is, moving the decimal point to the right until only one non-zero digit appears before the decimal. In this case, 230,000 in standard form is 2.3 x 10⁵.
Marc earned $1,650 per month as an assistant technician at a recording studio. His new job pays $9.80 per hour with time and a half for all hours over 36 hours per week. How many hours of overtime per week will he need to work to earn the same amount per week as his current job?
Answers
Marc will need to work just over 4 hours of overtime each week at his new job, which pays $9.80 per hour and $14.70 per hour for overtime, to earn the equivalent of his previous monthly income of $1,650.
To determine the number of overtime hours Marc needs to work at his new job to earn the same monthly income he did at his previous job, we'll first calculate his weekly income at his old job, then use the overtime pay rates at the new job to find the equivalent number of hours needed.
Marc previously earned $1,650 per month. Assuming a standard 4-week month, his weekly income was:
$1,650 per month / 4 weeks per month = $412.50 per week.
At his new job, Marc earns $9.80 per hour with time and a half for all hours over 36 hours a week. This means his overtime pay is 1.5 times his hourly rate, which is:
$9.80 per hour x 1.5 = $14.70 per hour for overtime.
Marc's income for the first 36 hours at his new job would be:
36 hours x $9.80 per hour = $352.80
To earn the equivalent of his old weekly salary, we must make up the difference with overtime pay:
$412.50 (old weekly income) - $352.80 (new regular pay) = $59.70 needed from overtime.
To determine the overtime hours needed to make $59.70: $59.70 / $14.70 per hour = approximately 4.06 hours.
Therefore, Marc will need to work just over 4 hours of overtime each week to earn the same amount he did at his previous job.

Sheila is building a model for class. It's a tower that's designed to withstand high winds. She can use a maximum of 700 support beams and knows that each floor will require 22 beams. Sheila will track the number of beams that remain as she adds floors.
She can predict the number of beams that remain by using this function: remaining beams (y) is function of floor number (x).
How many beams will remain after she built 6 floors? Y=700-22(x)
Answers
then, after having 700 beams, she used 12, so: 700 - 132 = 568
So. 568 beams remain.

B) m= (5-0)/(10-0) = 1/2
C) m= undefined
D) m= 0
A) The slope of line that goes through the points (4, 1) and (2, 5) is -2.
B) The slope of line that goes through the origin and the point (10, 5) is
1 / 2.
C) Vertical lines has undefined slope.
D) The slope of line that goes through the points (1, 6) and (10, 6) is 0.
What is Slope?
Slope is defined as the steepness of the line.
Since, Slope of line passes through points (x₁ , x₂) and (y₁ , y₂) is;
m = (y₂ - y₁) / (x₂ - x₁)
Now,
A) The slope of line that goes through the points (4, 1) and (2, 5) is;
m = 5 - 1 / 2 - 4
m = 4 / -2
m = - 2
B) The slope of line that goes through the (0, 0) and the point (10, 5) is;
m = 5 - 0 / 10 - 0
m = 5 / 10
m = 1 / 2
C) A vertical line that goes through the point (6,-5) has undefined slope.
Because the horizontal change is 0 and we cannot divide a number by 0.
D) The slope of line that goes through the points (1, 6) and (10, 6) is;
m = 6 - 6 / 10 - 1
m = 0 / 9
m = 0
Thus,
A) The slope of line that goes through the points (4, 1) and (2, 5) is -2.
B) The slope of line that goes through the origin and the point (10, 5) is
1 / 2.
C) Vertical lines has undefined slope.
D) The slope of line that goes through the points (1, 6) and (10, 6) is 0.

Henry's rocket is designed to launch to a height of 100 feet in the air. The measurements so far have the launch height (h) varying no more than 4 feet. Which inequality below represents this scenario?
|h − 4| less than or equal to 100
|h + 4| greater than or equal to 100
|h − 100| less than or equal to 4
|h + 100| greater than or equal to 4
Answers
so answer is
|h − 100| less than or equal to 4
Answer:
|h − 100| less than or equal to 4
Step-by-step explanation:
We know the difference between h, the actual height, and the designed height, 100, is no more than 4.
This means that the actual height h could be up to 4 more than the designed height or up to 4 less than the designed height. This is why we use an absolute value inequality; this considers just the distance of 4 regardless of direction.
Since it can be "no more than" 4, we use less than or equal to; this gives us
|h − 100| less than or equal to 4

d. d = 8, e = 11
Answers
hope i helped
The coordinates of d and e b. d = –2, e = 12.
To find the coordinates of points D and E, we need to remember that they are the same distance from point F, which has a coordinate of 5. This means D and E are equidistant from F on the number line. Let's check each option to see which one satisfies this condition:
Option a: d = -7, e = -1
The distance from -7 to 5 is 12.
The distance from -1 to 5 is 6.
Since the distances are not equal, this option is incorrect.
Option b: d = -2, e = 12
The distance from -2 to 5 is 7.
The distance from 12 to 5 is also 7.
Since the distances are equal, this option is correct.
Option c: d = 0, e = 5
The distance from 0 to 5 is 5.
The distance from 5 to 5 is 0.
Since the distances are not equal, this option is incorrect.
Option d: d = 8, e = 11
The distance from 8 to 5 is 3.
The distance from 11 to 5 is 6.
Since the distances are not equal, this option is incorrect.
Therefore, the correct answer is option b: d = -2, e = 12.

A. P=3
B. P=4
C. P=6
D. P=10
Answers
Answer:
x=1, y=4
P=6
Step-by-step explanation:
We are given that
[tex]3x+y\leq 7[/tex]
[tex]x+2y\leq 9[/tex]
[tex]x\geq 0[/tex]
[tex]y\geq 0[/tex]
Objective function
[tex]P=2x+y[/tex]
We have to values of x and y that maximize the P and maximum value of P .
First we change inequality equation into equality equation
[tex]3x+y=7[/tex] (I equation )
[tex]x+2y=9[/tex] (II equation)
Equation I multiply by 2 and then subtract from II equation
[tex]-5x=-5[/tex]
[tex]x=1[/tex]
Substitute x=1 in equation I
Then, we get
[tex]3(1)+y=7[/tex]
[tex]3+y=7[/tex]
[tex]y=7-3=4[/tex]
The two equation intersect at point (1,4).
Substitute x=0 in equation I
Then , we get y=7
Substitute y=0 then
[tex]3x=7[/tex]
[tex]x=\frac{7}{3}=2.3[/tex]
The equation I cut the x- axis at point (2.3,0)and y-axis at (0,7).
Substitute x=0 in equtaion II
[tex]2y=9[/tex]
[tex]y=\frac{9}{2}=4.5[/tex]
Substitute y=0
Then, we get
[tex]x=9[/tex]
Therefore, the equation II cut the x- axis at point (9,0) and y axis at point (0,4.5).
Substitute x=0 and y=0 in inequality Equation I
[tex]3(0)+0=0< 7[/tex]
It is true . Therefore, shaded region below the line.
Substitute x=0 and y=0 in inequality equation II
Then, [tex]0+2(0)=0 < 9[/tex]
It is true. Therefore, the shaded region below the line.
The feasible region is bounded.The feasible region bounded by (0,0),(0,4.5),(2.3,0) and (1,4).
At (0,4.5)
[tex]P=2(0)+4.5=4.5[/tex]
At (2.3,0)
[tex]P=2(2.3)+0=4.6[/tex]
At (1,4)
[tex]P=2(1)+4=6[/tex]
At (0,0)
[tex]P=2(0)+0=0[/tex]
Hence, maximum value of P is 6 at (1,4).
