Answer:
Y ≈ 59.0°
Step-by-step explanation:
Using the Cosine Rule in Δ XYZ
cosY = [tex]\frac{x^2+z^2-y^2}{2xz}[/tex]
Here x = 22, y = 20, z = 22, then
cosY = [tex]\frac{22^2+18^2-20^2}{2(22)(18)}[/tex]
= [tex]\frac{484+324-400}{792}[/tex]
= [tex]\frac{408}{792}[/tex] , thus
Y = [tex]cos^{-1}[/tex] ( [tex]\frac{408}{792}[/tex] ) ≈ 59.0° ( to the nearest tenth )

Simplify the variable expression
Answers
Answer:
j-128
Step-by-step explanation:
just add the number so you do
j+16-148=4

j+16-148-(4)=0
We add all the numbers together, and all the variables
j-136=0
We move all terms containing j to the left, all other terms to the right
j=136

Maya is interning at a law firm over the summer and is paid by the hour. Her hourly wage is $52. Write two equations represent the proportional relationship between the wages she earns (w) and the number of hours (h).
Answers
Answer:
The two equations are;
w = 52 h
and h = w/52
Step-by-step explanation:
From the question, we are told that she earns $52 in an hour
So therefore ,
W(h)= 52h
where h is the number of hours she has worked and w is the wages earned for the number of hours worked
The two equations are;
w = 52h
or w/h = 52
At a restaurant, Brianna and Naomi each order an appetizer for $6.50 and an entree for $9.75. The sales tax is $0.98 and they leave a tip of $5.85. How much did Brianna and Naomi spend in all?
Answers
Given :
At a restaurant, Brianna and Naomi each order an appetizer for $6.50 and an entree for $9.75.
The sales tax is $0.98 and they leave a tip of $5.85.
To Find :
How much did Brianna and Naomi spend in all.
Solution :
Total expenses, T = Food + tax + tip
T = $( 6.50+9.75) + $0.98 + $5.85
T = $( 16.25 + 0.98 + 5.85 )
T = $23.08
Therefore, total expenses is $23.08 .
Hence, this is the required solution.
A banquet table is formed by placing three square-topped tables edge to edge. The square tabletop of each small table has an area represented by x2−6x+9. What is the overall length of the entire banquet table?
A.[tex]3x^{2} -9[/tex]
B.[tex]x-3[/tex]
C.[tex]3x^{2} -18x+27[/tex]
D[tex]3x-9[/tex]
Answers
Answer:
Option D: 3x - 9
Step-by-step explanation:
We are told that A banquet table is formed by placing three square-topped tables edge to edge.
This means means that the 4 sides are equal and the length of the entire banquet table is; 3 x side of the table
Now, the table has an area which is x² − 6x + 9.
Thus, one side will be a factor of the quadratic equation.
From quadratic formula, the factor of the equation is; (x - 3)(x - 3)
Thus,one side is (x - 3).
So, length of entire table is;
L = 3(x - 3)
L = 3x - 9

Order of Operations: BPEMDASEquality PropertiesAlgebra I
Solving systems of equations using substitution/eliminationStep-by-step explanation:
Step 1: Define systems
--5x - 9y = 33
-y - 1 = x
Step 2: Simplify systems
5x - 9y = 33
-y - 1 = x
Step 3: Solve for y
Substitute: 5(-y - 1) - 9y = 33Distribute 5: -5y - 5 - 9y = 33Combine like terms: -14y - 5 = 33Isolate y term: -14y = 38Isolate y: y = -19/7Step 4: Solve for x
Define: -y - 1 = xSubstitute: -(-19/7) - 1 = xSimplify: 19/7 - 1 = xSubtract: 12/7 = xRewrite: x = 12/7And we have our final answer!

What is a linear equation?A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.
The linear equation is given as,
y = mx + c
Where m is the slope of the line and c is the y-intercept of the line.
The equations are given below.
y = 2x
y = 2x - 7
The slope of both lines is the same. Then the line is parallel to each other.
But the first line is passing through the origin and the second line is passing through (0, -7).
The graph is given below.
