x = the remaining student's score
(2(30) + 1(30) + 3(80) + x)/8 = 50
[multiply each side by 8]
2(30) + 1(30) + 3(80) + x = 400
[simplify]
60 + 30 + 240 + x = 400
330 + x = 400
[subtract 330 from each side]
x = 70
Make a conjecture about the diagram below. Is AC greater than, less than, or equal to BC? Explain your reasoning.
Triangle A C B is sitting on horizontal line X Y. Points A and B of the triangle are on the line. Angle C B Y is 90 degrees.
Answer:
AC is greater than BC because segment AC is the hypotenuse of right triangle ABC, and the hypotenuse is the longest side of a right triangle.
The hypotenuse is the longest side of the triangle. Side AC of the triangle is its hypotenuse, thus greater than BC (segment and angle theorem of a triangle).
A triangle is a shape with three side and angles. Its longest side is referred to as hypotenuse. And this side is usually opposite to the greatest angle. Examples of triangle include: equilateral, isosceles, acute, right angles, obtuse angle etc.
The given question shows that triangle ACB is a right angled triangle. This is because <CBY = [tex]90^{o}[/tex].
So that;
<CBY + <CBA = [tex]180^{o}[/tex]
Now comparing side AC with BC:
The segment and angle theorem of a triangle states that: the longest side of a triangle is always opposite to the greatest angle.
Thus, since <CBA is the greatest of the angles here, then AC is the longest side.
Therefore, the side AC is the hypotenuse of the triangle and it is greater than BC.

online banking is safest when you use your home computer-yes or no?
Financial institutions use encryption technology to ensue your information when
you bank online.-yes or no
You cannot pay bills with online banking.-yes or no
Answer:
Yes
Yes
No
Explanation:
It is important to use your own personal computer when banking online. Using public computers put your information at risk. For example, your browser history can be easily retrieved by others when using public computers, so this allows them to access your bank account information or your password.
Financial institutions use "encryption" technology in order to ensure that a person's information will remain confidential. This technology prevents your information from being deciphered.
You can pay bills with online banking and this is very common nowadays. People usually pay their electricity bill, internet bill and online purchases through online banking.
Audra is looking at a diagram of an oxygen atom. Which particle(s) does she see inside the nucleus?
plz help this is like 30% of my grade :)
Answer:
C: protons and electrons are found in the nucleus.
Step-by-step explanation:
Ok! So all atoms are composed of three basic things, protons, neutrons, and electrons. There are two parts of an atom, the nucleus and the electron cloud that surrounds the nucleus. In the nucleus are the protons and neutrons, and in the electron cloud are the electrons. Therefore, the answer would be C: protons and electrons are found in the nucleus.
Protons and electrons are found in the nucleus. The correct option is C.
What are protons and electrons?A subatomic particle with a negative charge is an electron. A subatomic particle having a positive charge is called a proton. Protons are bound together in an atom's nucleus as a result of the strong nuclear force. A type of subatomic particle without charge is the neutron (they are neutral).
All atoms are composed of three basic things, protons, neutrons, and electrons. There are two parts of an atom, the nucleus and the electron cloud that surrounds the nucleus. In the nucleus are the protons and neutrons, and in the electron cloud are the electrons.

Point M is the midpoint of AB. The coordinates of point A are (−7, 1) and the coordinates of M are (−2, 2). What are the coordinates of point B?
Answer:
[tex]\huge{\boxed{\sf{ ( 3 , 3 ) }}}[/tex]
Step-by-step explanation:
Co-ordinates of point A = ( -7 , 1 )
Co-ordinates of point M = ( -2 , 2 )
Let the co-ordinates of point B be ( x , y )
A ( -7 , 1 ) [tex]\longrightarrow[/tex] ( x1 , y1 )
B ( x , y ) [tex]\longrightarrow[/tex] ( x2 , y2 )
Now,
Midpoint = [tex](\frac{x1 + x2}{2} , \frac{y1 + y2}{2} )[/tex]
⇒[tex]( -2 , 2 ) = ( \frac{-7 + x}{2} , \frac{1 + y}{2} )[/tex]
Finding the value of x :
⇒[tex]-2 = \frac{-7 + x}{2}[/tex]
Do cross multiplication
⇒[tex]-4 = -7 + x[/tex]
⇒[tex]-7 + x = -4[/tex]
⇒[tex]x = -4 + 7[/tex]
⇒[tex]x = 3[/tex]
Now, finding the value of y
⇒[tex]2 = \frac{1+y}{2}[/tex]
Do cross multiplication
⇒[tex]4 = 1+y[/tex]
⇒[tex]1+y = 4[/tex]
⇒[tex]y = 4 - 1[/tex]
⇒[tex]y = 3[/tex]
Hence, The co-ordinates of point B = ( 3 , 3 )

what are the intersections between the lines y=x squared and 6x + 3y= 24?
Answer:
The intersection points between the functions are (-4,16) and (2,4)
Step-by-step explanation:
Intersection Between Functions
We are given the functions:
[tex]y=x^2[/tex]
[tex]6x+3y=24[/tex]
To find the intersections between them, we have to solve the system of equations. Let's start by simplifying the second equation by 3:
[tex]2x+y=8[/tex]
Now we substitute [tex]y=x^2[/tex] into this equation:
[tex]2x+x^2=8[/tex]
Solve the quadratic equation by any of the available methods.
Subtract 8:
[tex]2x+x^2-8=0[/tex]
Sort the polynomial:
[tex]x^2+2x-8=0[/tex]
Factor:
[tex](x+4)(x-2)=0[/tex]
Solve:
[tex]x=-4, x=2[/tex]
Now find the y-coordinate of each solution:
[tex]y=x^2=(-4)^2=16[/tex]
The point is (-4,16)
For x=2:
[tex]y=x^2=2^2=4[/tex]
The point is (2,4)
The intersection points between the functions are (-4,16) and (2,4)

Danielle earns a 7.25% commission on everything she sells at the electronics store where she works. She also earns a base salary of $625 per week. How much did she earn last week if she sold $4,500 in electronics merchandise? Round your intermediate calculations and answer to the nearest cent.
Answer:
She earned 1,076 dollars and 25 cents.
Step-by-step explanation:
x = 7.25 * 4,500 / 100
x = 7.25 * 45
x = 326.25
So commission earned is 326.25 $
We need to add this to her base salary for the week, so:
750 + 326.25 = 1, 076.25
Therefore she earned 1,076 dollars and 25 cents.

6.38 * 10^3 = 6380 kilometers.
Hope this helped!
Answer:
6380km
Step-by-step explanation:
10³ is just 1000 if you think about it.
6.38 multiplied by 1000 would just mean you need to move the decimal to the right 3 times.
Also if you look up the earth's radius on wikipedia, it says 6,371km which is close to 6,380km.

The function f has the property that as x gets closer and closer to 4, the values of f(x) get closer and closer to 7. Which of the following statements must be true?
Answer:
C
Step-by-step explanation:
x going to 4 is given by limx->4 and closer to 7 is given by =7
The correct statement is [tex]\lim_{x \to 4} f(x)[/tex] = 7.
What is function?An expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).
Given statement:
x gets closer and closer to 4, the values of f(x) get closer and closer to 7.
So, x gets closer and closer to 4 shows
x-> 4
and, f(x) get closer and closer to 7 shows
f(x)=7
Combining both we can write using the limit function x gets closer and closer to 4 require limit
[tex]\lim_{x \to 4} f(x)[/tex] = 7.

What is the transformation of a graph?Transformation is rearranging a graph by a given rule it could be either increment of coordinate or decrement or reflection.
If we reflect any graph about y = x then the coordinate will interchange it that (x,y) → (y,x).
Given the coordinate (3,-2) transformed in coordinate (1,0)
Now,
3 + x = 1
x = -2
It means graph shift 2 units left.
Now,
-2 + y = 0
y = 2
It means the graph shifts 2 units up.
Hence "The translation of points (3,-2) → (1,0) is 2 units up and 2 units left".

Tonya’s dog-walking service charges a flat rate of $20 per month, plus $3 per mile that each dog is walked. Beth does not charge a monthly fee for her dog-walking service, but she charges $5 per mile that each dog is walked.
Part A
Choose the equation that can be used to find the number of miles m for which Tonya and Beth would charge the same amount.
A. 20 + 3m = 5m
B. 20 = 3m + 5m
C. 20 + 5m = 3m
D. 20 + m = 8m
Part B
m = _____ miles
Answer:
A 10 miles
Step-by-step explanation:
If I'm not mistaking I'm pretty sure we can write the two problems with an equal sign between as we're trying to find the same amount.
Using this information, we know that we Automatically have a +20 charge with a 3 dollar charge for every mile walked. Now we have 20+3x=
Now we plug in the 5x to get 20+3x=5x
From here you subtract 3x and you get 20=2x. Now divide!
