Ms. Janis teaches math to 254 students each day. she grades one paper for each student each day. if Ms. Janis teaches for 25 days this month, how many papers does she grade?
please help me
Answer:
6,350
Step-by-step explanation:
254 times 25 is 6,350
Answer:
6350 Papers
Step-by-step explanation:
254 x 2 = 508
508 x 10 = 5080
(This is basically 254 x 20)
254 / 2 = 127
127 x 10 = 1270
(This is basically 254 x 5)
5080 + 1270 = 6350
Which one of the following values of k makes the trinomial 9x^2 + kx + 64 a perfect square
a 24
b 48
c 16
d 42
Answer:
it is C 16
Step-by-step explanation:
x² - kx + 64
Since we are looking for a perfect square, then we need to take the square root of 64 to find the factors: √64 = 8
So, the factors are: (x - 8)(x - 8)
Foil (or distribute) to get: x² - 16x + 64 The k-value is 16
Evaluate the expression: +22 - (8 - 6) = 3

→ Exponents
→ Multiplication
→ Division
→ Addition
→ Subtraction
________________
[tex]\frac{3}{5}+2^2-\frac{2}{5}\left(8-6\right)\div \:3=4\frac{1}{3}[/tex]
1) Parentheses:

Solve for n: 9^(n-1) = (1/3)^(4n-1) Show your work.
Answer:
n=1/2 after being simplified
Step-by-step explanation:
Use Division Distributive Property:
9^n-1=1/3^4n-1 then convert both sides to the same base
3^2(n-1) = 3^-(4n-1)
cancel the base of 3 on both sides
2(n-1) = -4n+1
then expand 2n-2=-4n+1
add 2 to both sides 2n=4n+1+2
simplify: -4n+1+2 to -4n+3
2n=-4n+3
add 4n to both sides: 2n+4n=3
simplify: 2n+4n to 6n
6n=3
divide both sides by 6
n=3/6
simplify and n=1/2

100 POINTS AND BRAINLIEST!!
Answer:
A. $47,143
Step-by-step explanation:
Given information:
Current annual lifestyle cost ≈ $33,000Take home pay estimation = 70%Gross income: Total income before any deductions.
If take home pay is approximately 70% of the annual gross income, to be able to maintain the current lifestyle, 70% of the annual gross income needs to be at least $33,000.
Let x = annual gross income
Therefore:
70% of x = $33,000
⇒ 0.7x = 33000
⇒ x = 33000 ÷ 0.7
⇒ x = 47142.8571...
Therefore, the annual gross income needs to be $47,143 (nearest dollar) to maintain the current lifestyle.
Annual gross income be y
70% of y=330000.7y=330007y=330000y=330000/7y=47143Option A
How can I find 75% of any number?
Answer:
75% can be converted into a decimal, any percentage can.
Once converted, 75% is actually .75
At this point you can move the decimal place two place up, and put it over 100, in a fractal form
75/100
You can then simplify this to
3/4
You can then use this fraction as a conversion factor with any number, for example if we took the number 8
8∗3/4
2∗3/1=6

What is thissss someone help
Answer:
1. Neither
2. Odd
3. Odd
4. Even
Step-by-step explanation:
Graphically, an equation is even if it is symmetrical across the y-axis. An equation is odd if it is symmetrical after folded over y and x. An equation is neither if it fulfills neither requirement.
Algebraically, an equation is even is f(x) = f(-x), and an equation is odd if f(-x) = -f(x).
Hope it helps :) and let me know if you want me to elaborate.

will the point (2, 6) be on the graph of y=3x
Answer:
the answer is yes it will
Answer:
yes
Step-by-step explanation:
since (x,y) is 2,6, we can take x as 2 and y as 6. For the answer to be yes, y=3x must be equal to the x and y values. Lets plug in the values. Is (6)=3(2)?
3 times 2 is 6! So the answer is yes.

In what ways the sum of x + x and the product of x × x different with each other ?
Answer:
x+x refers to x being added
For Eg:
5+5=10
x+x refers to x being multiplied
For Eg:
5*5 = 25
So you can see that the product is greater than sum
Not always though,
For Example take 2+2=4
and 2*2 = 4
Interestingly 2^2 is also equal to 4
Hope this helps!

!!I WILL MARK BRAINEST!! number 6 please. i did the question but i’m not sure if i even got the answer correct. please help me, thank you!
Step-by-step explanation:
If everything is kept in terms of x then:
For part A the general area would just be side times side.
Here it would be (30x)(4x)
=[tex]120x^{2}[/tex]
For part B since you have 5 sections divide the long side by 5.
[tex]\frac{30x}{5} =6x[/tex]
Then multiply by the other side of the rectangle to find the area of one section.
6x(4x)=[tex]24x^{2}[/tex]
Alternatively you could just divide the large area by 5 to get the area of one section.
[tex]\frac{120x^{2} }{5}=24x^{2}[/tex]

Answer:
Oh ok
Step-by-step explanation:
An expression is defined as a set of numbers, variables, and mathematical operations. The given statement "Double the product of eight and a number" in the form of an expression can be written as 16x.
What is an Expression?In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.
Let the unknown number be represented by x.
The product means multiplication, therefore, we need to double or multiply the product or multiplication of eight and x.
Thus, The given statement in the form of an expression can be written as,
2(8 × x)
= 2(8x)
= 16x
Hence, the given statement "Double the product of eight and a number" in the form of an expression can be written as 16x.

Answer:
m < 2 = 45°
Step-by-step explanation:
m < 1 and m < 3 are corresponding angles that lie on the same side of the transversal. Since they are corresponding angles, then it means that they have the same measure.
Therefore, if m < 1 = 135°, then m < 3 = 135°.
Also, the sum of m < 2 and m < 3 = 180° because they are supplementary angles.
Therefore:
m < 2 + m < 3 = 180°
m < 2 + m < 135° = 180°
m < 2 = 180° - m < 135°
m < 2 = 45°

Matthew is taking a multiple choice test with a total of 40 points available. Each question is worth exactly 2 points. What would be Matthew's test score (out of 40) if he got 9 questions wrong? What would be his score if he got xx questions wrong?
Answer:
22 points
Step-by-step explanation:
If their are fourty points avaliable and each question is worth two points, then there are a total of twenty questions (20 times 2 is 40). Therefore, if he gets nine questions wrong, he would have gotten 11 right. Because we know that each question is two points, we may just multiply 11 by 2, which means he has gotten a score of 22 points!
