Answer:
The perimeter is 31 inches
Step-by-step explanation:
The perimeter is the sum of all the sides.
The formula for the area of the rectangle is : [tex]length*width[/tex]
To work this out you would first need to divide the area of 42 by the length of 12, this gives you 3.5. This is because the formula for the area of a rectangle is length multiplied by the width, and so by dividing the area by 12 we are working out the perimeter of the missing side.
Now that we know the lengths of both sides we can begin working out the perimeter. You can do this by multiplying the lengths by 2. Multiply 12 by 2,which gives you 24. Multiply 3.5 by 2, which gives you 7.
The final step in calculating the perimeter would be to add the values of 24 and 7, this gives you 31. This is because the perimeter is sum of all of the lengths of a shape.
1) Divide 42 by 12.
[tex]42/12=3.5[/tex]
2) Multiply 12 by 2.
[tex]12*2=24[/tex]
3) Multiply 3.5 by 2.
[tex]3.5*2=7[/tex]
4) Add 7 and 24.
[tex]24+7=31[/tex]

How many weeks of school will Jacob have to attend this quarter before he will have taken a total of 16 quizzes?
Answer:
4 weeks
Step-by-step explanation:
The number of weeks for a total of 16 quizzes will be 4 weeks.
What is an expression?
Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
It is given that Jacob took a total of 12 quizzes over the course of 3 weeks. The number of weeks for 16 quizzes will be calculated as below:-
12 quizzes = 3 weeks.
1 quizzes = 3 / 12 weeks
16 quizzes = ( 3 / 12 ) x 16 = 4 weeks
Therefore, the number of weeks for a total of 16 quizzes will be 4 weeks.

Answer: C. Outside the circle.
Step-by-step explanation:
To find whether point M lies on the circle, first derive the equation of the circle from the radius and center given.
Equation of a circle:
[tex](x-h)^2 + (y-k)^2=r^2[/tex]
Substitute the coordinates (0, 0) for h and k, and 2 times the square root of 3 for r:
[tex]x^2 + y^2 = 12[/tex]
Now, substitute the points (-3, 2) for x and y:
[tex]9 + 4 = 12[/tex]
This equation is incorrect, as the (x, y) coordinates produce a greater value than the radius of the circle squared. When this occurs, the point given is outside of the circle.
(A point like (1, 1), when substituted into the equation and solved to get 1 + 1 = 12, would be inside the circle, as its (x, y) coordinates produce a smaller value than the radius of the circle squared.)
As such, the correct answer is C.

Eighteen men take 15 days
to dig 6 hectares of land
Find the number of men
required to dig 8 hectares
in 12 days?
Answer:
number of men = 30
Step-by-step explanation:
18 men takes 15 days to dig 6 hectares of land.
18 men will take 12 days to dig ? hectares of land
cross multiply
hectares of land = 12 × 6/15
hectares of land = 72/15
hectares of land = 4.8 hectares
18 men will take 12 days to dig 4.8 hectares of land
? number of men will take 12 days to dig 8 hectares
cross multiply
number of men = 18 × 8/4.8
number of men = 144/4.8
number of men = 30

2x^2 = 3x
Answer:
x = 1.5
Step-by-step explanation:
2x^2 = 3x
divide whole eqn by x
2x = 3
x= 3/2 =1.5
Answer:
x=2/3 or x=0
Step-by-step explanation:
1) Let's solve by factoring
since "x" is common in both 2x^2 and 3x let's take that out
first we have to bring "3x" to the left
so
2x^2-3x
next, factor of "x"
x(2x-3)=0
to solve, divide by x on both sides:
(2x-3)=0
add 3
2x=3
divide by 2
x=3/2
or x=0(since x(2x-3)=0, logically if x=0 then this equation would make sense)

The function f(x) and g(x) are graphed below. If g(x)=f(x+k) what is the value of k?
Answer:
The value of k = -6
Step-by-step explanation:
First lets concentrate at the most obvious point, the top. Top(f) = ( 4, 1) and Top(g) = ( -2, 1).
The translation factor k ( which is called a vector ), which accounts for the trandlation of any point of f(x) --> g(x).
To translate the x coordinate of the top from 4 to -2, you have to subtract 6 of it.
Because 4 -6 = -2
Hence the factor k must be -6.
The value of k = -6
Find the probability:
You roll a fair six-sided die twice. The first roll
shows a five and the second roll shows a six.
The probability is 1/36.
The outcome of the first roll does not affect the outcome of the second roll, and so the probability of rolling any number on a fair six-sided die remains 1/6 for both rolls. This means that the probability of rolling a 5 the first time and a 6 the second time are both 1/6, and to find the probability of 2 things happening we have to multiply, so we end up with 1/6 × 1/6 = 1/36

Determine the nth term formula for each of the following sequences and find the limit if it exists.
3, 3,-3, 3,
Answer:
aₙ = (-3) (-1)ⁿ⁻¹
limit does not exist
Step-by-step explanation:
-3, 3, -3, 3, ...
This is an alternating geometric series where the first term is -3 and the common ratio is -1. The nth term is therefore:
aₙ = (-3) (-1)ⁿ⁻¹
Since the sequence alternates between -3 and 3, the limit as n approaches infinity of aₙ does not exist.

What is expression ?
In mathematics, if two or more numbers or variables present with one or more mathematical operations, then the statement is called expression.
Example : 4x-3y+4, where x,y are variables, 3 & 4 are numbers and they are operated with addition and subtraction, so this is an expression.
What is the value of given expression ?Here, in the problem, x = -1 & y = 3
The given expression is 2(xy - 7) .....(1)
Now, we have to put the values of x & y in (1),
So, 2(xy - 7)
= 2{(-1)(3)-7}
= 2{-3-7}
= 2×(-10)
= -20
So, the value of the expression is -20

A dilation centered at the origin maps the point (1,3) to the point (4,12). What is the scale factor of the dilation?
Answer:
4
Step-by-step explanation:
4,12
1,3
4/12=4
12/3=4
The point (1,3) is mapped to the point by a dilation with the origin as the center. The dilation's scale factor is 4.
Explain about the Dilation?Resizing an item uses a transition called dilation. Dilation is used to enlarge or contract the items. The result of this transformation is an image with the same shape as the original.
Finding the dilation's centre point is the first step in determining the scale factor. Next, we measure the distances between the centre point and various points on the preimage and the image. The ratio of these distances gives us the scale factor, as Math Bits Notebook accurately states.
The basic formula to find the scale factor of a dilated figure is: Scale factor is equal to the difference between the dimensions of the old and new shapes.
= 4,12
= 1,3
= 4/12 =4
= 12/3 =4

X-intercept:
y-intercept:
Answer:
x-intercept: (13/3, 0)
y-intercept: (0, -13)
Step-by-step explanation:
y+1 = 3x-12
y= 3x-13
For y-intercept:
y= 3(0) -13
y=-13
For x-intercept:
0=3x-13
3x=13
x=13/3
The intercepts of the line will be,
x-intercept: (13/3, 0)
y-intercept: (0, -13)
What is an intercept?A y-intercept, also known as a vertical intercept, is the location where the graph of a function or relation intersects the coordinate system's y-axis. This is done in analytic geometry using the common convention that the horizontal axis represents the variable x and the vertical axis the variable y. These points satisfy x = 0 because of this.
Given that y+1=3(x - 4). The x-intercept and y-intercept will be calculated as,
y+1 = 3x-12
y= 3x-13
For y-intercept:
y= 3(0) -13
y=-13
For x-intercept:
0=3x-13
3x=13
x=13/3
Therefore, the x-intercept is (13/3, 0) and the y-intercept is (0, -13).

A is the event where Anwar selects an even numbered card.
B is the event where she choses a heart.
we have 3 even cards (and two of them are hearts)
we have 4 hearts (2 of them are even)
The probability of event A is Pa = 3/6 = 1/2
