Create a sample division problem with a 2-digit divisor and give an incorrect answer, showing the steps taken to get the incorrect answer.
Answer:
Incorrect Answer Below
Step-by-step explanation:
Problem: We have a total of 28 candies that need to be divided evenly between 4 students.
(Incorrect) Solution: In order to solve this problem we can seperate the total number of candies into single digits and then divide each digit by 4 like so...
2 / 4 = 0.5
8 / 4 = 2
Now that we have the answer of both of these divisions we can simply add these values together to get the number of candies each student will get
0.5 + 2 = 2.5 candies

find the slope PLEASE HELP
Answer:
-1/4
1
-1/4
1
Step-by-step explanation:
Slope is obtained thus :
(y2 - y1) / (x2 - x1)
Slope ST :
S(1, 4) ; T(5, 3) ;
x1 = 1, y1 = 4 ; x2 = 5 ; y2 = 3
Slope ST = (3 - 4) / (5 - 1) = - 1 / 4
Slope TU :
T(5, 3) ; U(3, 1)
x1 = 5, y1 = 3 ; x2 = 3 ; y2 = 1
Slope TU = (1 - 3) / (3 - 5) = - 2/ - 2 = 1
Slope UV :
U(3, 1) ; V(-1, 2)
x1 = 3, y1 = 1 ; x2 = - 1 ; y2 = 2
Slope UV = (2 - 1) / (-1 - 3) = 1 /-4 = - 1/4
Slope SV:
S(1, 4) ; V(-1, 2)
x1 = 1, y1 = 4 ; x2 = - 1, y2 = 2
Slope SV = (2 - 4) / (-1 - 1) = - 2 / - 2 = 1

Work out the equation of the line which has a gradient of 3 and
passes through the point (-2, 4).
Answer:
y=3x+10
Step-by-step explanation:
We can use standard form to write the equation of this line.
y=mx+b
where m=the slope (or gradient) of the line
and where b= the y-intercept
now to solve...
we know the slope (gradient) or m=3
so we can put this in the equation.
y=3x+b
now we must solve for b.
in order to this we can subsitute the coordinate (-2,4) into x and y since
a coordinates values/variable representation is (x,y) -> (-2,4)
So subsituting the coordinate in...
y=3x+b
4=3(-2)+b
simplify.
4=-6+b
b=10
This means the y-intercept=10
so...
y=3x+10
is the equation of the line.

Colton is about to ride a straight water slide. The launching platform is at the top of a tower that is 8 meters tall. The splash pool at the end of the slide is 15 meters from the base of the tower. How long is the water slide itself? Show your work.
Answer:
The length of the water slide itself is 17 meters
Step-by-step explanation:
Here, we want to calculate the length of the water slide
from the description given in the question;
we have a right angled triangle where the height of the tower, the distance from the base of the tower and the length of the slide itself represents the sides of the triangle
From the description given in the question, the water slide length represents the slope of the right triangle formed
thus, mathematically by using Pythagoras’ theorem;
The square of the hypotenuse equals the sum of the squares of the two other sides
Let us call the length of the water slide y
y^2 = 8^2 + 15^2
y^2 = 64 + 225
y^2 = 289
y = √289
y = 17 meters

Which ordered pair is a solution of the equation y+1=3(x-4)
Step-by-step explanation:
When x = 4 and y = -1,
(-1) + 1 = 3(4 - 4) = 0.
Hence (4, -1) is an ordered pair.
When x = 5 and y = 2,
(2) + 1 = 3(5 - 4) = 3.
Hence (5, 2) is an ordered pair.
Therefore the answer is C.

R2. Definition of corresponding anglesR3. Corresponding angles postulateR5. Supplement PostulateS7. m∠2 + m∠3 = m∠1 + m∠3S8. m∠1 + m∠3 = 180°Question 8 (4 points) Find the values of x and y if NO = x + 2y, MO = 3x, PQ = 6x + 4, and OQ = 2y + 4.
Answer:
x = 12 and y = 16
Step-by-step explanation:
Given the following lengths;
NO = x + 2y,
MO = 3x,
PQ = 6x + 4, and
OQ = 2y + 4.
The following postulates are true;
MN = PQ
Since MO + ON = MN
MN = 3x + x+2y
MN = 4x + 2y
Recall that PQ = 6x+4
Equating both expressions;
4x + 2y= 6x+4
Collect like terms;
4x-6x + 2y = 4
-2x + 2y = 4
x - y = -4 ...... 1
Also MO = OQ
3x = 2y + 4
3x-2y= 4 ....2
from 1; x = -4 + y
Substitute into 2:
3x-2y= 4
3(-4+y)-2y = 4
-12+3y-2y = 4
-12+y = 4
y = 4 + 12
y = 16
Since x = -4+y
x = -4 + 16
x = 12
Hence x = 12 and y = 16

Solve for r. This is for combinations and permutations.
Answer:
○ D) A and C
Step-by-step explanation:
[tex]\displaystyle \frac{n!}{r![-r + n]!} = {}_nC_r[/tex]
All you need to do is plug each choice into the formula:
[tex]\displaystyle \frac{10!}{2![-2 + 10]!} \Longrightarrow \frac{[2][3][4][5][6][7][8][9][10]}{2[-2 + 10]!} \longrightarrow \frac{[2][3][4][5][6][7][8][9][10]}{2[(2)(3)(4)(5)(6)(7)(8)]} \\ \\ \boxed{45} = \frac{90}{2}[/tex]
OR
[tex]\displaystyle \frac{10!}{8![-8 + 10]!} \Longrightarrow \frac{[2][3][4][5][6][7][8][9][10]}{[(2)(3)(4)(5)(6)(7)(8)][-8 + 10]!} \\ \\ \boxed{45} = \frac{90}{2}[/tex]
So, from what you see, both values of [tex]\displaystyle r[/tex] work. In fact, when using the formula pertaining to combinations, you will see that each result has a “repetitive pattern”. This is something you must look out for when using this formula.

Josie took a long multiple-choice, end-of-year vocabulary test. The ratio of the number of problems Josie got incorrect to the number of problems she got correct is : . If Josie missed questions, how many did she get correct? *---------- If josie missed 20 questions how many did she get correct--- PLEASE HELP ME
Answer:
36 correct answers
Step-by-step explanation:
Given that,
The ratio of the number of problems Josie got incorrect to the number of problems she got correct is 2:9.
Josie missed 8 questions
Let incorrect answers be 2x and that of correct answers be 9x.
ATQ,
2x = 8
x = 4
Correct answers = 9x
= 9(4)
= 36
Hence, she will get 36 correct answers.

Aisha is a cyclist. She rode 3 ¾ miles in ⅓ hours. A. How fast was she going in miles per hour?
Answer:
11 1/4 miles per hour
Step-by-step explanation:
Put the mixed number in improper form to make it easier. You get 15/4 miles in 1/3 hours. You want the miles for 1 hour. So you multiply 15/4 miles by 3 to get 45/4 miles, or 11 1/4 miles per hour

Step-by-step explanation:
Jiangsu divided 751.6 by 10 to the second power and obtained a quotient of 0.7516. Yessenia thinks the quotient. Who has the reason? Explain your answer.
Answer:
Yessenia is correct.
Step-by-step explanation:
Supose Yessenia thinks the quotient is 7.516, then Yessenia is correct.
The reason why Yessenia is correct is that, if we interpret the question mathematically, we have:
[tex]= \dfrac{751.6}{10^2}[/tex]
[tex]= \dfrac{751.6}{100}[/tex]
From above the decimal point will shift to the left twice since we are dividing 751.6 by 100, which is:
= 7.516 and not 0.7516
Tell whether the relation is a function. {(-5, -3), (-1, 3), (4, 3), (8, 8)}
Given:
The relation is {(-5, -3), (-1, 3), (4,3), (8, 8)}.
To find:
Whether the given relation is a function or not.
Solution:
A relation is called a function, if there exist a unique output for each input.
We have, a relation given as
{(-5, -3), (-1, 3), (4,3), (8, 8)}
Here, all x-values are different. So, each x-value has a unique y-value.
Thus, there exist a unique output for each input.
Therefore, the given relation is a function.

Roger spent 22 minutes on his math homework and 25.08 minutes on his spelling
homework. He spent percent more time on his spelling homework.
Answer:
114%
Step-by-step explanation:
okay, so we know he spent 22 minutes on math and 25.08 on spelling.
m=22
s=25.08
so to find a percent, you have to divide s/m
s/m= 25.08/22
s/m= 1.14
because this is a decimal, we have to convert it to a percent
114%
to check the answer, multiply 22 times 114%
the answer is 25.08, so we know we got the right answer.
