A quadrilateral has angle measures of 120 degrees ,37 degrees and 48 degrees what is the measure of the forth angle
Answer:
Let the fourth angle be x
Angles in a quadrilateral add up to 360°
To find the fourth angle add all the known angles and subtract them from 360°
That's
x + 120+37+48=360
x + 205 = 360
x = 360-205
x = 155°
Therefore the fourth angle is 155°
Hope this helps
George believes the Art Club students at his school have an unfair advantage in being assigned to the art class they request. He asked 500 students at his school the following questions: "Are you in the Art Club?" and "Did you get the art class you requested?" The results are shown below:
Art class and in art club: 100
Art class and not in art club: 265
Total in art class: 365
Not in art class and in art club: 65
Not in art class and not in art club: 70
Total not in art class: 135
Total in art club: 165
Total not in art club: 335
Total students: 500
Help George determine if all students at his school have an equal opportunity to get into the art class they requested. Show your work, and explain your process for determining the fairness of the class assignment process.
Answer:
If you're not an art club member and you want to request the art class, you have a greater chance of getting into our class. There isn't an equal opportunity for all students to get into the art class they requested, therefore the class assignment is unfair.
As a non-art club member, you have a 79% chance of being assigned to the art class they request.
As an art club member, you have a 61% chance of being assigned to the art class they request.
Step-by-step explanation:
265, divided 335, that's 79%. So this means that if you are not in the art club and you wish to enroll in an art class, you have 79% of percent of being admitted in your request in art class.
Total not in art club 335/ Total students 500= 0.791= 0.79%
Art class and in art club 100/ Total in art club 165= 0.606 = 0.61%
Non art club requested 79% against art club requested 61%.

There are eight marbles in a bag. Four marbles are blue (B), two marbles are red
(R) and two marbles are green(G)
Steve takes a marble at random from the bag.
(i) What is the probability that Steve will take a blue marble.
(ii) What is the probability that Steve will take a green marble.
(iii) What is the probability that Steve will take a yellow marble.
Answer:
i. 4/8 or 1/2, ii. 2/8 or 1/4, iii. 0/8
Step-by-step explanation:
In the problem it says that there are 8 marbles in total, so for number 1 it'll be 4/8 or 1/2 since 4 of the marbles are blue. Number 2 will be 2/8 because there are only 2 green marbles and you can simplify 2/8 to 1/4. The last one would be 0 since the problem didn't mention that there are yellow marbles. Hope this helps :)
Find the value of the trigonometric ratio, cos L.
Answer:

Answer:
7/10
Step-by-step explanation:
10 dishes
3 meat dishes = ( chicken, hamburger, meatloaf)
10-3 = 7 that are not meat
P ( not meat) = not meat / total
=7/10
Answer:
7/10
Step-by-step explanation:
There are a total of 10 meals to choose from. There is 1 chicken, 1 hamburger, and 1 meatloaf. Together they make 3 meat choices. So there are 3/10 of probability of choosing meat. We are looking for the probability of not choosing meat which would be 7/10. This is because the whole amount of meals 10- 3 meat chooices equals 7 total of meals that are not meat. Which gives us the probability of 7/10.

Find the length of LW. If entering your answer as a decimal, round your final answer to the nearest hundredth. LW = ___ Units
Answer:
17.5 units
Step-by-step explanation:
We are given the following values from the diagram above
LA = 3.5 units
AY = Midpoint = 7.0 units
LW = unknown
Step 1
The first step is to determine what AW is.
From the right angled triangle, we obtained these proportions
LA : AY = AY : AW
= LA/AY= AY/AW
Cross Multiply
7× 7 = 3.5 × AW
49 = 3.5 AW
AW = 49/3.5
AW = 14 units
Step 2
LW = AW + LA
LW = 14 units + 3.5 units
LW = 17.5 units
Answer:
17.5 units

Find the area of this circle. Area = _______ in2. Use 3.14 for pi and round to the nearest tenth. A. 35.8 B. 28.3 C. 254.3 D. 1017.4
Answer:
A ≈ 254.5 in²
Option C
Step-by-step explanation:
Area of a Circle Formula: A = πr²
d = 2r
Since we are given diameter d, we simply divide by 2 to get radius r:
r = 18/2 = 9
Then we simply plug it into the formula:
A = π(9)²
A = 81π
A = 254.469
A circle with a radius of 9 inches has an area of 254.3 square inches. The of aarea circle is calculated using the formula πr², where π is a mathematical constant approximately equal to 3.14 and r is the radius of the circle.
Hence, the correct option is C.
The area of a circle is calculated using the formula A = πr², where A is the area and r is the radius of the circle. In this case, the radius is 9 inches, so the area is given by:
In this case, the radius is 9 inches, so the area of circle is given by,
Area = pi × [tex]9^{2}[/tex]
Area = 3.14 × 81
Area= 254.3
The value of pi is approximately 3.14, so the area of the circle is approximately 254.3. However, the question asks for the area rounded to the nearest tenth, so the answer is 254.3.

Graph the line that passes through the points (4, 3) and (1,6) and determine the equation of the line.
Answer:
y = -x + 7
Step-by-step explanation:
Slope-Intercept Form: y = mx + b
Slope Formula: [tex]m = \frac{y2-y1}{x2-x1}[/tex]
Step 1: Find slope
m = (6 - 3)/(1 - 4)
m = -1
Step 2: Find b
y = -x + b
6 = -1 + b
b = 7
Step 3: Rewrite linear equation
y = -x + 7
Answer:
y = -x + 7
Step-by-step explanation:
(x1, y1) = (4 , 3)
(x2, y2) = (1 , 6)
[tex]slope=\frac{y_{2}-y{1}}{x_{2}-x_{1}}\\\\=\frac{6-3}{1-4}\\\\=\frac{3}{-3}\\\\=-1\\\\y-y_{1}=m(x-x_{1})\\\\[/tex]
m = - 1; (4,3)
y - 3 = (-1)(x -4)
y - 3 = -x + 4
y = -x + 4 + 3
y = -x + 7

Answer:
C
Step-by-step explanation:
You first distribute within the parentheses which is -(-z-2). This is going to make everything positive as everything in the parentheses is negative. You should get z+2. Next, you plug that back in. It should be-3z+z+2. You simplify to get -2z+2. Hope this helps!
Answer:
see below
Step-by-step explanation:
-3z -( -z -2)
The first step is to distribute the minus sign
-3z --z --2
A negative negative is a positive
-3z +z +2
Then combine the like terms
-3z+z +2
Answer

Isabel purchased bananas and apples at a grocery store. She spent a total of $9.90 on 3 pounds of apples and 2 pounds of bananas. If the apple cost 3 times as much per pound as bananas, what is the cost per pound of apples??
A) $0.90
B) $1.80
C) $2.70
D) $3.60
Answer:
C. $2.70
If one pound of apples cost 3 times the amount of a pound of bananas, then a pound of apples costs; $2.70.
The cost per pound of apples will be $2.70, which is the correct answer would be option (C).
What is the equation?The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.
Let the cost per pound of apples be x, and the cost per pound of banana be y
She spent a total of $9.90 on 3 pounds of apples and 2 pounds of bananas.
So, 3x + 2y = 9.90 ....(i)
And the apple cost 3 times as much per pound as bananas.
So, x = 3y
y = x/3 ....(ii)
Substitute the value of y = x/3 in the equation (i), and solve
3x + 2(x/3) = 9.90
3x + 2x/3 = 9.90
11x/3 = 9.90
11x = 2.97
x = 2.97/11
x = 2.70
Thus, the cost per pound of apples will be $2.70.

Expand to write an equivalent expression: -1/4(-8x+12y)
Answer:
8x -12
Step-by-step explanation:
Use the distributive property. 16 outside wishes to go inside and multiply each term; you get 16x/2 which is 8x minus ¾ of 16 which is 12.
Answer:
2x-3y
Step-by-step explanation:
To expand this expression, use the distributive property.
[tex]-\frac{1}{4}(-8x+12y)[/tex]
To distribute, multiply each term inside the parentheses by the number outside the parentheses.
[tex](-\frac{1}{4}*-8x)+(-\frac{1}{4} *12y)[/tex]
Multiply -1/4 and -8x first.
[tex]((-\frac{1}{4}*-8)x)+(-\frac{1}{4} *12y)[/tex]
[tex]2x+(-\frac{1}{4} *12y)[/tex]
Next, multiply -1/4 and 12y.
[tex]2x+ ((-\frac{1}{4} *12)y)[/tex]
[tex]2x+ -3y[/tex]
A +- becomes a -
[tex]2x-3y[/tex]
