Geraldo has 17 gold chains as calculated by the basic arithmetic operation of division.
Division is an arithmetic operation in which a number is broken down into smaller pieces.
One of the four fundamental arithmetic operations, or how numbers are combined to create new numbers, is division.The other operations are multiplication, addition, and subtraction.In its most basic form, the division of two natural numbers involves, among other things, counting how many times one number appears inside another. This count does not necessarily have to be an integer.The number that is divided is called the dividend, the number that is dividing is called divisor and the quotient is the number that is result of the division.Now Geraldo has a 34 inch long gold chain. Therefore if he cuts it into 2-inch long pieces then we will divide 34 by 2 and the quotient will give us the number of chains.
∴ 34 ÷ 2 = 17
Hence Geraldo will have 17 chains.

Step-by-step explanation:
Jimmy walks to his school every morning. He leaves home everyday at the same time. And the school starts at the same time everyday at 8 am. If he walks at 40 meters per minute, he will reach his school 5 minutes late. If he walks at 60 meters per minute, he will reach his school 3 minutes before the bell rings.
Answer: The bell rins at 8:19 AM, and the distance between Jimmy's house and the school is 960 meters.
Step-by-step explanation:
Let's define the variables:
T = Number of minutes after 8 AM such that the school's bell sounds.
D = Distance between jimmy's house and the school, in meters
And remember the relation:
Distance = Speed*Time.
We know that:
"If he walks at 40 meters per minute, he will reach his school 5 minutes late."
D = (T + 5)*40
"If he walks at 60 meters per minute, he will reach his school 3 minutes before the bell rings."
D = (T - 3)*60
Then we have a system of equations:
D = (T + 5)*40
D = (T - 3)*60
We can take the quotient of these two equations and get:
D/D = ((T + 5)*40 )/((T - 3)*60)
1 = (4/6)*(T + 5)/(T - 3)
Now let's solve this for T.
6/4 = (T + 5)/(T - 3)
(6/4)*T - (6/4)*3 = T + 5
(6/4)*T - T = 5 + (6/4)*3
T*(2/4) = 5 + 18/4 = 5 + 9/2
T = (4/2)*(5 + 9/2) = 19
Then the bell sounds 19 minutes after 8AM, at 8:19 AM
And with this, we can find the distance D:
D = (T + 5)*40 = (19 + 5)*40 = 960
The distance between Jimmy's house and the school is 960 meters.

Liberty Center Middle School has 1,200 students. In Sophia’s class, 3 out of 4 students borrowed library books. Based on these results, how many students at the school would you expect to borrow library books?
Answer:
We expect 900 students to borrow library books
Step-by-step explanation:
Proportions
If two variables are proportional, then one of them can be obtained as the other times a fixed number.
If x and y are proportional, then:
y=k.x
Where k is the constant of proportionality
The value of k can be obtained by dividing y/x.
That division, also called ratio gives us the proportion to be applied to future calculations.
In Sophia's class, 3 out of 4 students borrowed library books.
This gives us a proportion ratio of 3/4.
If we apply that same proportion to the rest of the Liberty Center Middle School, with 1,200 students, then, we expect to have
3 / 4 * 1200 = 900 students borrowing library books.
We expect 900 students to borrow library books

What is the argument of z = 1/16 - square root of 3/16 i?
Answer:
A
Step-by-step explanation:
Edg2020
The value of the argument of z is -π/3.
What is the argument of z?The angle that the line from Ф, z to the origin creates with the positive direction of the real axis is known as the argument of z is Ф, and it is variously represented by the symbols arg ( z ), (z) or Ф. Because it is an argument of z is Ф, then 2 nπ + Ф is likewise a valid argument, the argument of z can take on any number of conceivable values.
We define a singular value known as the major argument of z to be more precise.
Given z = 1/16 - √3/16i
equation of z is x + iy
here x = 1/16 and y = -√3/16
to find the angle,
tanФ = y/x
tanФ = (-√3/16)/(1/16)
tanФ = -√3
Ф = tan⁻¹(-√3)
Ф = -π/3
Hence arguement of z is -π/3.

Determine if the lines are parallel, perpendicular, or neither.
3y = -2x + 18 and 6x + 9y = 18
Parallel
Perpendicular
Neither
Answer:
parallel
Step-by-step explanation:
1st step get the equations in y=mx+b
3y = -2x + 18
(÷ each side by 3)
y = -2/3x + 6
6x + 9y = 18
(subract 6x to get it to the other side)
9y = -6x + 18
(÷ both sides by 9)
y = -6/9x + 2
(simplify -6/9)
y = -2/3x +2
2nd step look at the equations
y = -2/3x + 6 and y = -2/3x +2
The lines are at different places and will never touch, having same slope theres never a possibility they would look something like this \\

b) 86.5 years
Step-by-step explanation:
All values are rounded to 2 decimal places
a) We can find line by using y =mx+b
[tex]y=mx+b\\m=\frac{y^{2}-y^{1} }{x^{2}-x^{1}}\\m=\frac{69.7-47.3}{1960-1900} \\m=\frac{22.4}{60} \\m=\frac{28}{75}\\c=y-intercept\\y-intercept=47.3\\y=\frac{28}{75} (x-1900)+47.3[/tex]
Therefore the line of best fit is [tex]y=\frac{28}{75}(x-1900)+47.3\\[/tex]
b) We can do this by using the formula of the best fit line to estimate the life expectancy of someone born in 2005
[tex]y=\frac{28}{75}(x-1900)+47.3\\y=\frac{28}{75}(2005-1900)+47.3\\y=\frac{28}{75}\times105+47.3\\y=86.5[/tex]
Therefore the estimated life expectancy of someone born in 2005 is 86.5 years

Alexa took a test and lost 3 points for each of the 7 questions she got wrong. She earned an additional 5 points for answering a bonus question correctly. How many points did Alexa receive or lose overall?
Answer:
Alexa lost 16 points overall
Step-by-step explanation:
To determine whether Alexa had a net receipt or loss of points, we will fine the total points received or lost, and find the difference:
points lost:
3 point for each of the 7 questions she answered wrong
lost point = 3 × 7 - 21 points
Points received:
5 points for answering a bonus question
point received = 5 point
The points lost (21) is greater than the points received (5), hence, there was a net loss. The net loss is calculated as follows:
points lost - points received
= 21 - 5 = 16
∴ Alexa lost 16 points overall
Solve the following system of equations graphically on the set of axes below. y=3x−3 , x+y=5
Answer:
x=2, y=3
Step-by-step explanation:
First, graph both equations on a rectangular coordinate system (see attached screenshot). Then, simply figure out where these two lines intersect. Since they intersect at (2,3), x=2 and y=3.
Plugging these values in the equations for x and y, you can see if these are the correct answers:
(3)=3(2)-3, (2)+(3)=5
Since both of these are true, you have the right answer.
Hope this helps!
Two linear equation has their solutions on the points where they intersect each other.
The solution of the given system of equations is:
x = 2, y = 3.
How to determine the solution of system of linear equations graphically?Each linear equation represents a straight line.
If both the given lines intersect at one point, then that point's coordinate is the solution of the given system of the equations.
If both the given lines are parallel, then there is no intersection and thus no solution.
If both the lines are coincident(that is, lying over each other fully), then there are infinite points of intersection, as they touch each other on infinite points, and thus infinite solutions to the given system of equations exist.
Using method of substitution to solve the system of equations:[tex]y = 3x-3\\ x+y = 5 [/tex]
Substituting the value of y from first equation in the second equation, we get:
[tex]x + y = 5\\ x + (3x-3) = 5\\ x+3x = 5+3\\ 4x = 8 \\ x = 2\\ [/tex]
Thus, putting this value of x in first equation, we get:
[tex]y = 3x - 3\\ y = 3 \times 2 - 3\\ y = 6-3\\ y = 3[/tex]
Thus, the system has one solution and it is x = 2, y = 3.
Using graphing, we can see that point of intersection is (x,y) = (2,3)
