PLS MARK BRAINLIEST
Step-by-step explanation:
Sn = n/2(2a+(n-1)d)
a=6
a+ 4d= 18
6 +4d= 18
4d = 12
d = 3
162= n/2(12+(n -1)3)
324=n(12 + 3n-3)
324=12n + 3n^2 - 3n
3n^2 + 9n-324=0
3n^2+ 36n-27n -324 =0
3n(n+12) -27(n+12)= 0
3n-27 =0; n+ 12=0
n=9 ; n= -12
since n can't be negative n=9
The number of terms is 9
How do I solve this problem??
Answer:
32
Step-by-step explanation:
Because Triangle QPS has equal sides, it is an equilateral triangle. Which means its angles are 60°. 134-60 = 74. Because Lines QS and QR are equal angles QSR and QRS are the same. 180-74-74 = 32

87 calories per 3/4 cup. How many calories per 1 cup
since 87 calories = ³/₄ cup
let x calories = 1 cup
⇒ 87 = ³/₄ x
x = (87)(⁴/₃)
x = 116 calories
∴ if 87 calories is in 3/4 cup, then 1 cup contains 116 calories.Copy the picture and put a dot on where i put it

what is x/y+z=w to make x the subject of the formula
We can make x the subject of the equation by moving all the other terms to the opposite side of the equal sign while x is on the next.
x/y+z=w [multiply both sides by y+z]
x = w (y + z)
After watching Donald Duck in Mathmagic Land, please type out three things that you learned from the video. Did you like the video? Why or why not? Please answer all parts to the question
Answer:
Hope this helps
Step-by-step explanation:
Mathmagic Land had taught me more about math that I never knew before. I learned that everything can be involved with math. It all starts at the Pythagoreans which were the Greek. An example of how math is used today, is by playing billiards.
In billiards, you have to have a good technique of how your going to hit the ball, (good angles,) and you have to have a precise calculation of the angle your going to hit it at.I also learned when you cut shapes like a sphere, it just makes more and more shapes.
This is what I learned watching the Mathmagic Land Video.
Yes, Donald Duck in Mathmagic Land taught me alot of things I did not know before.

Rectangle has side 5 cm so one side of triangle will be 5cm
area of triangle is = 1/2lb
= 1/2 5*4
=10 cm^2
area of rectangle is l*b = 5*3= 15 cm^2
are of the shape is 10+ 15= 25 cm^2
Area of rectangle is 6*8 = 48 m^2
Area of triangle is = 1/2 *8*2= 8 m^2
area of the shape is 48+8= 56m^2

Find the missing angle measures.
What is m∠1?
a. 50
b. 105
c. 100
d. 60
Answer: C
Step-by-step explanation:
we know that the third angle of the triangle with 50 and 50 degrees is 80 because a triangle has 180 degrees. we also know that 80 + the measure of angle 1 = 180 and 80 + 100=180

The range of function graphed above is :
[tex] \{y| - 3 \leqslant y \leqslant 4 \}[/tex]This graph shows a reciprocal parent function.
Which statement best describes the function
A. The function is always increasing
B. The function is increasing when x<0
C. The function is never increasing
D. The function is increasing when x>0
Answer:
C. The function is never increasingStep-by-step explanation:
According to the graph, the line goes down in both sections as the value of x increases. It means the function is always decreasing.
Correct answer choice is:
C. The function is never increasingThe best describes the function is,
''The function is never increasing.''
What is mean by Function?A relation between a set of inputs having one output each is called a function. and an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).
Given that;
This graph shows a reciprocal parent function.
Since, We have;
According to the graph, the line goes down in both sections as the value of x increases.
It means the function is always decreasing.
Hence, Correct answer choice is:
C. The function is never increasing.

PLEASE HELP !!!! SYSTEMS OF EQUATIONS
In the student government election, Maddie received 20% more votes than her opponent. A total of 1,485 votes were cast for both candidates. How many votes did Maddie receive?
Answer:
Maddie got 810 votes
Step-by-step explanation:
We'll call Maddie's votes x, and her opponent's votes y.
x + y = 1485
x = y + 0.20y (because she got the same number of votes as her opponent, PLUS another 20% of that number. Divide 20% by 100 to get the decimal equivalent) This can also be written as x = 1.2y
So our system is
x + y = 1485 and
x = 1.2y
Substitute the second equation's value for x into the first equation:
1.2y + y = 1485 then solve for y
2.2y = 1485
divide both sides by 2.2
y = 675
substitute that in and solve for x
x + y =1485
x + 675 = 1485
subtract 675 from both sides
x = 810
Please let me know if you have questions on this answer. Hope it helps.

The midpoint of an is m (-6,1). If the coordinates of a are (-5,7), what are the coordinates of b
Answer:
B= (-7, -5)
Step-by-step explanation:
The midpoint point formula is (X1 plus X2) divided by 2 to get the x value of the midpoint and do the same for the Y value, ( Y1 plus Y2) divided by 2. So, because you already have the midpoint you have to work backwards. So for the x value of B the formula would be (-5 + X) divided by 2 equals -6 and then you just solve for X. Same thing for the Y value (7 + Y) divided by 2 equals 1. Then you should get both values for B (-7, -5)
