Answer:
A. a = √2
b = √2
Step-by-step explanation:
Apply trigonometric function to find a and b:
Reference angle = 45°
Hypotenuse = 2
Opposite side = a
Adjacent side = b
✔️Apply SOH to find a, which is:
Sin 45 = Opp/Hyp
Sin 45 = a/2
2*Sin 45 = a
2*1/√2 = a (sin 45 = 1√2)
2/√2 = a
Rationalize
(2*√2)/(√2*√2) = a
2√2/2 = a
√2 = a
a = √2
✔️Apply CAH to find b, which is:
Cos 45 = Adjacent/Hypotenuse
Cos 45 = b/2
2*Cos 45 = b
2*1/√2 = b (Cos 45 = 1√2)
2/√2 = b
Rationalize
2√2/2 = b
√2 = b
b = √2

EASY MATH CHALLENGE NEED EXPLANATION 20 POINTS The board game Kings crown has, red, green, and gold gems for the players to earn as they play. The game has 1/3 as many green games as red gems. It has 1/6 as many red gems as gold gems. What fraction of the game's gems are gold?
Answer:
9/11
Step-by-step explanation:
Let r = number of red gems
Let n = number of green gems
Let p = number of gold gems
n= (1/3)r - - > multiply both sides by 3 - - > r = 3n
r = (1/6)p - - > multiply both sides by 6 - - > p = 6r
So the number of reds (r) is 3x the number of greens (n)
And the number of golds (p) is 6x the number of reds.
So for every 1 green, we have 3 reds and for every red we have 6 golds.
So for every 1 green, we have 3 reds and 18 golds.
So we add 1 + 3 + 18 = 22 gems.
Out of the 22 gems, 18 are gold.
18/22 = 9/11 are gold
Kaitlyn buys books from a book club. She calculates the total cost, in
dollars, of each order using the formula 15b + 5. In her formula, b
represents the number of books she orders.
a) What is the total cost of ordering four books?
b) What is the total cost of ordering two books?
c) What is the total cost of ordering one book?
Answer:
c=what is the total cost of ordering one book..
Step-by-step explanation:
Given function:
15b+5What this means:
15b+5 means that 15+5..b=1 for 15+15so if the cost of the book is 15 dollars it adds 5 since you brought that book or for other reasons.15+5=1 book and b represents it.Therefore, b=the total cost of ordering one book..

Gabriela has an average daily balance of $232.94 on her credit card. Her card charges 9.25% annual interest. What will her monthly finance charge be?
Answer:
$21.55
Step-by-step explanation:
Gabriela's monthly finance charge will be $21.54.
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that Gabriela has an average daily balance of $232.94 on her credit card. Her card charges 9.25% annual interest.
The finance charge will be calculated as:-
Charge = ( 232.94 x 9.25%)
Charge = 232.94 x 0.0925
Charge = $21.54
Therefore, the monthly finance fee for Gabriela will be $21.54.

Is 3/2 greater than 1? Or Less than
Answer:
3/2 is greater than 1
Step-by-step explanation:
A little trick to immediately know if a number is more or less than when it involves fractions versus whole numbers is that improper fractions will always be greater than 1.
If you want to confirm this, dividing 3/2 equals 1.5, ergo 1.5 > 1.
In essence, improper fractions will always represent a number greater than one contrasted to proper fractions because if you put it on a perspective (let's say you have 13 pie slices but you only needed 12, that means there is a pie slice that's extra that makes it greater than the original pie slices).

An appliance salesperson earned $32.80 in commission for selling a refrigerator for $820. At that rate, how much would the salesperson earn in commission for selling a microwave oven for $340?
Answer:
Salesperson would earn $13.6 in commission for selling a microwave oven for $340.
Step-by-step explanation:
We are given that an appliance salesperson earned $32.80 in commission for selling a refrigerator for $820.
We have to find how much would the salesperson earn in commission for selling a microwave oven for $340.
Firstly, we will the find the rate at which the salesperson gets a commission in % terms.
So, Percentage rate of commission is given by;
Rate of commission=(Commission earned ÷ Selling Price of refrigerator) 100
= = = 4%
Now, this rate will be used to find the commission earned on selling a microwave oven for $340, i.e;
Commission earned for selling a microwave oven = 4% of Selling price of microwave oven
= = $13.6
Therefore, salesperson would earn $13.6 in commission for selling a microwave oven for $340.

Find the values of x and y.
A. x = 42, y = 26.3
B. x = 47, y = 30
C. x = 42, y = 30
D. x = 47, y = 26.3
Answer:
C
Step-by-step explanation:
2x + 1 = 85 (Alternate Interior Angles Theorem)
2x = 84
x = 42
(3y + 5) + (2x + 1) = 180 (Linear Pair Theorem)
3y + 5 + (85) = 180
3y + 5 = 95
3y = 90
y = 30
Answer:
x = 42, y = 30
Step-by-step explanation:
Alternate angles are equal so
85 = 2x + 1
2x = 84
x = 42°
Linear pair
(3y + 5) + (2x + 1) = 180
3y + 5 + 85 = 180
3y = 90
y = 30°
So I think the answer is x = 42° and y = 30°.

What is the equation of the line that passes through the point (5,-1) and has a
slope
of 1/5
Answer:
y=1/5x-2
Step-by-step explanation:
You want to find the equation for a line that passes through the point (5,-1) and has a slope of 1/5.
First of all, remember what the equation of a line is:
y = mx+b
Where:
m is the slope, and
b is the y-intercept
To start, you know what m is; it's just the slope, which you said was 1/5. So you can right away fill in the equation for a line somewhat to read:
y=1/5x+b.
Now, what about b, the y-intercept?
To find b, think about what your (x,y) point means:
(5,-1). When x of the line is 5, y of the line must be -1.
Because you said the line passes through this point, right?
Now, look at our line's equation so far: . b is what we want, the 1/5 is already set and x and y are just two "free variables" sitting there. We can plug anything we want in for x and y here, but we want the equation for the line that specfically passes through the the point (5,-1).
So, why not plug in for x the number 5 and for y the number -1? This will allow us to solve for b for the particular line that passes through the point you gave!.
(5,-1). y=mx+b or -1=1/5 × 5+b, or solving for b: b=-1-(1/5)(5). b=-2.
The equation of the line that passes through the point (5,-1) with a slope of 1/5
is
y=1/5x-2

Total cash = $26,200
Total assets = $457,000
Total equity = $156,630
Find:
Common-size percent for cash
Computation:
Common-size percent for cash = [Total cash/Total assets]100
