Answer:
The answer for this question would be 21x (when simplified).
Answer:
9 (3x + 1) - 3(2x + 3)
we have to simplify the given expression
↝ 9(3x+1) - 3(2x+3)
↝ (27x+9) - (6x+9)
↝ 27x + 9 - 6x - 9
↝ 27x - 6x + 9 - 9
↝ 21x
So, the required answer is 21x .

if the sides of a triangle QRS are QR=10X-6, RS=6X-15,QS=X+24, find a range of possible values for X?
The range of the possible values for X will be;
⇒ X < 5
What is mean by Triangle?
A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.
Given that;
The sides of a triangle QRS are;
⇒ QR=10X - 6,
⇒ RS = 6X - 15,
⇒ QS = X + 24,
Now,
We know that;
The sum of two sides of a triangle is always greater than the third side.
So, We can formulate;
⇒ 10X - 6 < (6X - 15) + (X + 24)
⇒ 10X - 6 < 7X + 9
⇒ 10X - 7X < 9 + 6
⇒ 3X < 15
⇒ X < 5
Thus, The range of the possible values for X will be;
⇒ X < 5

Using the interquartile range, which of the following are outliers? Select all correct answers.
Select all that apply:
3
6
21
60
Answer:
3 and 6
Step-by-step explanation:
IQR = Q3-Q1=96-62=34
Lower Outlier = Q1 - 1.5*IQR = 62 - 1.5*34 = 11
Any Value under 11 is Considered as Outlier
Then 3 and 6 are Outliers
Upper Outlier = Q3 + 1.5*IQR = 96 + 1.5*34 = 147
Any Value Above 147 is Considered as Outlier
There is no Value above 147
The Only Outliers are 3 and 6

During the soccer season, Cathy made 27 of the 54 goals she attempted. Karla made 18 of the 45 goals she attempted. Patty made 34% of the goals she attempted. List the athletes in order of their goal-scoring percentage from least to greatest.
Answer:
Patty, Karla, Cathy
Step-by-step explanation:
The scoring percentage of goals attempted can be computed by dividing goals made by those attempted, then multiplying the result by 100%.
__
Cathy's rate is ...
27/54 × 100% = 50%
Karla's rate is ...
18/45 × 100% = 40%
Patty's rate is ...
given as 34%
__
By least to greatest scoring rate, the athletes are ...
Patty (34%), Karla (40%), Cathy (50%)
Which segments are perpendicular to
CD.
Answer:
GF where G is at (6,5) and F is at (10,2)
Step-by-step Explanation:
Perpendicular lines always have the negative reciprocal as the other line as their slope. This is such that (1/3) × (-3/1) = -1, so -3/1 is the negative reciprocal to 1/3.
This means we are looking for a line with the slope -3/4, and we can find the slopes by using the formula (y2 - y1)/(x2 - x1).
For the first option, LM, we get (9 - 3)/(-10 - 2) = 6/-12 = -1/2, so it is not this.
For the second option, GF, we get (2 - 5)/(10 - 6) = -3/4, which is the slope we were looking for. This means that the second option is our answer.

Percentage of funds raised is 44 % , Fraction of funds raised is (11/25) and Fraction of funds raised in decimal form is 0.44.
What is Percentage?To find the % of a number, divide it by its value, then multiply the result by 100. Percentage is a relative value that denotes one tenth of any quantity. As one percent (symbolised as 1%) is equal to one tenth of anything, 100 percent stands for everything, while 200 percent refers to double the amount specified.
As per the given data:
In the diagram given, we can find the total amount of funds to be raised and the amount of fund which is raised currently.
Total amount to be raised = $250,000
Amount already raised = $110,000
Percentage of funds raised = (110,000/250,000) × 100 = 44 %
Fraction of funds raised = (110,000/250,000) = (11/25)
Fraction of funds raised in decimal form = 0.44
Hence, Percentage of funds raised is 44 % , Fraction of funds raised is (11/25) and Fraction of funds raised in decimal form is 0.44

3. Consider the straight line x + y = 1 and the family of straight lines that pass
through the origin given by y = mx. As m changes the line rotates about the
origin. Solve these two systems of linear equation and find their points of inter-
section. Is there always a solution - If yes, briefly explain why. If not - for what
a
values of m is there no solution.
Answer:
solution: (1/(1+m), m/(1+m))no solution for m = -1 (lines are parallel)Step-by-step explanation:
Two distinct lines will always have a point of intersection, provided they are not parallel. That is, the system of equations {x +y = 1, y = mx} will have a unique solution as long as m ≠ -1.
The solution to the system can be found by substitution:
x +mx = 1
x(1 +m) = 1 . . . . factor out x
x = 1/(1+m) . . . . . divide by the coefficient of x; we must have m ≠ -1
y = m/(1+m) . . . . find the y-coordinate of the solution
The point of intersection is (1/(1+m), m/(1+m)).

The above solution is undefined when the denominator is zero: m = -1. There is no solution for m = -1.

Consider the line y=9x-5. Find the equation of the line that is perpendicular to that line and passes through the point (-3,-3)
Answer:
y=(-1/9)x-(10/3)
Step-by-step explanation:
Since the line is perpendicular to y=9x-5, the slope of that line would be the opposite of the reciprocal of the original slope value. In this case, the slope of the line would be -1/9. So we have y=(-1/9)x+? Since we know a point, (-3, -3), we can input this back into our original equation and we have: -3=(1/3)+? We simplify and we have ?=-10/3. Therefore the final equation of the line that is perpendicular to that line and passes through the point (-3,-3) is y=(-1/9)x-(10/3).

A triangle has side lengths of 54, 72 & 90. Is it a right triangle? Explain.
No, there always has to be an odd number for it to work out to be a right triangle.
No, it is obtuse.
No, it is acute.
Yes, the Pythagorean Theorem works out to be equal.
Yes, because 52 + 72 > 90.
Answer: C: Yes, the Pythagorean Theorem works out to be equal.
Step-by-step explanation:
to test if a triangle is right angled or not, just use the Pythagorean Theorem:
a²+b²=c², where a and b are the two shorter sides of the triangle, and c is the longest side.
plugging this in:
54²+72² ?= 90²
2916 + 5184 ?= 8100
8100 = 8100
Yes! Its correct, so we know that this triangle is a right triangle. the justification is C: Yes, the Pythagorean Theorem works out to be equal.

Step-by-step explanation:
In the figure,
145° and 3x - 5 are vertically opposite angles which are equal, so
=> 3x - 5 = 145°
=> 3x = 145 + 5
=> 3x = 150°
=> x = 150°/3
=> x = 50°
Hope it helps you!!Answer:
x = 50
explanation:
vertically opposite angles are of equal measure.
solve:
3x - 5 = 145
3x = 145 + 5
3x = 150
x = 50
the smiths spend 11% of their budget on entertainment. their total budget this year is $1,000 more than last year, and this year they plan to spend $4,620 on entertainment. what was their total budget last year?
Answer: $41000 Was the Smiths family budget last year.
Step-by-step explanation:
First you take $4620 and DIVIDE it by .11 you will get $42000 and since last year had $1000 less to spend you subtract $1000 from $42000 to get $41000 for the budget last year.
