I didn’t mean to click C but yea I need help
Answer:
C.
Step-by-step explanation:
It says from least to greatest. You start off looking at the whole numbers and 1 is the least. Your going to start at 1 2/5 (that rules off A and B). The next number you need to compare is 3/10 and 5/8. Since 5/8 is bigger than 3/10 the answer would be C.

Step-by-step explanation:
Joseph claims that a scatterplot in which the y-values increase as the x-values increase must have a linear association. Amy claims that the scatterplot could have a nonlinear association. Which statement about their claims is true?
Joseph is correct because only a line will increase along the whole data set. The scatterplot will have a positive, linear association.
Joseph is correct because only a line will decrease along the whole data set. The scatterplot will have a negative, linear association.
Amy is correct because a nonlinear association could increase along the whole data set, while being steeper in some parts than others. The scatterplot could be linear or nonlinear.
Amy is correct because only a nonlinear association could increase along the whole data set. A line has the same slope at any point, but a curve can get steeper at different points.
Answer: Choice C
Amy is correct because a nonlinear association could increase along the whole data set, while being steeper in some parts than others. The scatterplot could be linear or nonlinear.
======================================================
Explanation:
Just because the data points trend upward (as you go from left to right), it does not mean the data is linearly associated.
Consider a parabola that goes uphill, or an exponential curve that does the same. Both are nonlinear. If we have points close to or on these nonlinear curves, then we consider the scatterplot to have nonlinear association.
Also, you could have points randomly scattered about that don't fit either of those two functions, or any elementary math function your teacher has discussed so far, and yet the points could trend upward. If the points are not close to the same straight line, then we don't have linear association.
-----------------
In short, if the points all fall on the same line or close to it, then we have linear association. Otherwise, we have nonlinear association of some kind.
Joseph's claim that an increasing trend is not enough evidence to conclude the scatterplot is linear or not.
Answer:

B) Joseph is correct because only a line will decrease along the whole data set. The scatterplot will have a negative, linear association.
C) Amy is correct because a nonlinear association could increase along the whole data set, while being steeper in some parts than others. The scatter plot could be linear or nonlinear.
D) Amy is correct because only a nonlinear association could increase along the whole data set. A line has the same slope at any point, but a curve can get steeper at different points.

Find an equation of the line perpendicular to Y equals 3X -3 and passes through the point -3 and -1
Answer:
y = - [tex]\frac{1}{3}[/tex] x - 2
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = 3x - 3 ← is in slope- intercept form
with slope m = 3
Given a line with slope m then the slope of a line perpendicular to it is
[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{3}[/tex] , then
y = - [tex]\frac{1}{3}[/tex] x + c ← is the partial equation
To find c substitute (- 3, - 1) into the partial equation
- 1 = 1 + c ⇒ c = - 1 - 1 = - 2
y = - [tex]\frac{1}{3}[/tex] x - 2 ← equation of perpendicular line

Rhombus JKLM is shown below. Find m∠KLM.
A.36°degree
B.38°degree
C,72°degree
D.76°degree
Answer:
Option D
Step-by-step explanation:
Properties of a rhombus,
1). Diagonals of a rhombus bisect the opposite angles.
2). Sum of adjacent two angles of a rhombus is 180°.
By property (1),
Diagonal JL will bisect the angles ∠MJK and ∠KLM.
Therefore, m∠KLM = 2(5x + 3)°
Similarly, diagonal KM will bisect the angles ∠JKL and JML.
Therefore, m∠JKL = 2(9x - 11)°
By property (2),
2(9x - 11)° + 2(5x + 3)° = 180°
9x - 11 + 5x + 3 = 90
14x - 8 = 90
14x = 98
x = 7
Since, m∠KLM = 2(5x + 3)°
= 2(5×7 + 3)°
= 76°
Therefore, Option D will be the answer.

------------------------------
Area of pond
a = πr²
Area of path
a = πr²/10
Combined Area
a = πr² + πr²/10
a = π(r² + r²/10)
---------------------------
The Combined Area can also be expressed as
a = π(r + 1.5)²
a = π(r² + 3r + 2.25)
-----------------------------
Set the areas equal
π(r² + r²/10) = π(r² + 3r + 2.25)
Divide both sides by π
r² + r²/10 = r² + 3r + 2.25
Subtract r² from both sides
r²/10 = 3r + 2.25
Multiply both sides by 20
2r² = 60r + 45
Subtract 60r + 45 from both sides
2r² - 60r - 45 = 0

$1.50 is what fraction of $6.00?
Answer:
$1.50 is [tex]\frac{1}{4}[/tex] of $6.00
Step-by-step explanation:
In order to answers this, we should put $1.50 as the numerator, and $6.00 as the denominator, then simplify it and get the following...
[tex]\frac{1.50}{6.00} = \frac{1.50 / 1.50}{6.00/1.50} = \frac{1}{4}[/tex]
Ken and Ivan had some sweets. After Ken gave away 5/7 of his sweet, he had 2/3 as many sweets as Ivan. Ivan then gave away 120 sweets and he had 1/4 as many sweets as Ken. How many sweets did each of them have at first?
Answer:
Ivan had 288 sweet while Ken had 672 sweets
Step-by-step explanation:
Let the number of sweets owned by Ken and Ivan be k and v respectively.
After Ken gave away 5/7 of his sweet, what he had left
= k - 5k/7
= 2k/7
he had 2/3 as many sweets as Ivan then
2k/7 = 2v/3
Divide both sides by 2 and cross multiply
7v = 3k
Ivan then gave away 120 sweets, Ivan would have
v - 120 = k/4
multiply both sides by 4
4v - 480 = k
7v = 3(4v - 480)
7v = 12v - 1440
12v - 7v = 1440
5v = 1440
v = 1440/5
= 288
7v = 3k
7 * 288 = 3k
k = 7 * 288/3
= 672

If you put $25 each month into a savings account that paid a simple interest rate of 6.5% each year, how much would you have in your account at the end of two years?
Answer:
$339.00
Step-by-step explanation:
If you put $25 each month into a savings account that paid a simple interest rate of 6.5% each year, how much would you have in your account at the end of two years?
We solve the above question using the Equation:
A = P(1 + rt)
P = Principal = Amount deposited each month = $25
The amount deposited in a year = $25 × 12 months = 300
Calculation:
First, converting R percent to r a decimal
r = R/100 = 6.5%/100 = 0.065 per year.
Solving our equation:
A = 300(1 + (0.065 × 2)) = 339
A = $339.00
Therefore, you would have $339 in your account after 2 years

10) The second angle in a triangle is 3° less than twice the first angle. The third angle measure 8° more than
twice the first angle Find each angle.
Answer:
35, 67 and 78
Step-by-step explanation:
the angles are:
n, 2n-3 and 2n+8
there are 180 degrees in a triangle, so adding those terms together will give us 180
5n + 5 = 180
180 - 5 = 175
5n = 175
175 / 5 = 35
n = 35
now we have n we can put it in to the formula we have for the angles at the start:
n = 35
2n - 3 = 67
2n + 8 = 78
so the angles are
35, 67 and 78
Look at this diagram. What are x and y?
Answer:
The answer is x = 13 and y = 5.
Step-by-step explanation:
From the diagram, we know that there are two congruent legs of the triangle on the left (indicated by the lines). This means that two angles in this triangle measure 5x degrees. Because the third angle of the triangle is supplementary to the 130 degree angle, we know it must measure (180-130) or 50 degrees. We can apply this supplementary argument to the triangle on the right as well. Looking at both triangles, we can create the following equations using the idea that the interior angles of a triangle must add to 180 degrees total. This gives us the following equations:
5x + 5x + 50 = 180
10y + 5 + 6x - 3 + 50 = 180
Let's begin by solving the first equation, since it only contains one variable.
5x + 5x + 50 = 180
We can start by combining like terms on the left side of the equation.
10x + 50 = 180
Then, we can subtract 50 from both sides of the equation.
10x = 130
Next, we can divide both sides by 10.
x = 13
Now that we know the value for x, we can take our second equation (that came from the triangle on the right side) and solve for y.
10y + 5 + 6x - 3 + 50 = 180
Let's begin by simplifying the equation a little bit.
10y + 6x + 52 = 180
We can subtract 52 from both sides of the equation.
10y + 6x = 128
Now we can plug in the value for x we found above, x = 13, and simplify.
10y + 6(13) = 128
10y + 78 = 128
We should then subtract 78 from both sides of the equation.
10y = 50
Finally, we can divide both sides of the equation by 10.
y = 5
Therefore, the answer to the problem is x = 13 and y = 5.

Points D and E are midpoints of the sides of triangle ABC. The perimeter or the triangle is 48 units. What is the value of t?
Answer:
2 units
Step-by-step explanation:
A triangle is a polygon with three sides and three angles. Types of triangle are acute, obtuse, scalene, isosceles, equilateral and right angled triangle.
Since point D and E are midpoints of the sides of triangle ABC, hence:
AD = BD = 3t, BE = CE = 4t, AC = 7t + 6
The perimeter of triangle ABC = AC + BC + AB = AC + AD + BD + BE + CE;
Substituting:
48 = 7t + 6 + 3t + 3t + 4t + 4t = 21t + 6
48 = 21t + 6
21t = 42
t = 2 units
