Eduardo opened a credit card at a department store with an APR of 22.29% compounded semiannually. What is the APY on this credit card? (2 points) a 44.58% b 11.15% c 23.53% d 49.55%
Answer:
The correct option is c. 23.53%.
Step-by-step explanation:
The annual percentage yield (APY) can be calculated using the following formula:
APY = (1 + r / n)^n - 1 .............................. (1)
Where;
APY = Annual percentage yield = ?
r = Annual percentage rate = 22.29%, or 0.2229
n = Number of compounding period per year = Semiannually = 2
Substituting the values into equation (1), we have:
APY = (1 + 0.2229 / 2)^2 - 1
APY = 0.2353211025, or 23.53211025%
Rounding to 2 decimal places, we have:
APY = 23.53%
Therefore, the correct option is c. 23.53%.

How do you know if a point is a solution to a linear inequality
Answer:
To see if an ordered pair is a solution to an inequality, plug it into the inequality and simplify. If you get a true statement, then the ordered pair is a solution to the inequality. If you get a false statement, then the ordered pair is not a solution.

Farmer Brown has 360 feet of fencing to use to construct a rectangular enclosure for his prized goats. Which equation gives an area A as a function of the width w of the enclosure?
A(w)=180−w2
A(w)=360−w2
A(w)=180w−w2
A(w)=360w−2w2
Answer:
A(w) = 180w-w²
Step-by-step explanation:
Farmer Brown has 360 feet of fencing to use to construct a rectangular enclosure for his prized goats.
It means that the perimeter of the rectangle is 360 feet
The formula for the perimeter of a rectangular shape is given by :
P = 2(l+w)
l is length and w is width
ATQ,
2(l+w) = 360
(l+w) =180
l = 180 -w .....(1)
The formula for the area of a rectangle is given by :
A = lw
Put the value of l form equation (1).
A = (180-w)w
A(w) = 180w-w²
Hence, the correct option is (c).
(8a+5b−3)+3(b−3) Simplify

the slope of the line that passes through the points (2,3) and (5,9) is
Answer:
The slope is 6/3 or simplified is 2
Step-by-step explanation:
Stick to this formula
y2-y1/
x2-x1
9-3/
5-2 = 6/3 or 2
See attachment for further explanation
Hope this helps (:
The slope of the line that passes through (2, 3)(5, 9) is 2
Slope formula is describe below:m = y₂ - y₁ / x₂ - x₁Therefore, the slope of the line that passes through the points (2, 3)(5, 9) can be found as follows;
y₁ = 3
y₂ = 9
x₁ = 2
x₂ = 5
m = 9 - 3 / 5 - 2
m = 6 / 3
m = 2
slope = 2
Therefore, the slope of the line that passes through (2, 3)(5, 9) is 2

Four families went out for lunch. The total food
bill came to $167. The families also left a $30 tip for the
waitress. If each family spent the same amount, about how
much did each family spend on dinner? Explain how you
found your answer.
Answer:
Each family spent about 34.25 on dinner
Step-by-step explanation:
$167 - $30 (tip) = 137
137 ÷ 4 (for each family) = 34.25
BUT
if each family is seperate than they each spent about 11.75 on dinner
167 - (30 x 4) = 47
47 ÷ 4 = 11.75

33 is 5% of what number?
Answer:
660
Step-by-step explanation:
We know that .05x=33
To solve this just divide by .05
33/.05=660
Answer:
Let the number be x
[tex]5\% \: of \: x = 33 \\ \frac{5}{100} x = 33 \\ x = \frac{33 \times 100}{5} \\ \boxed{x =660}[/tex]
660 is the right answer.2x+22=5x-20, i need help with the steps and the answer. i suck at these :/
Answer:
x=14
Step-by-step explanation:
2x+22=5x-20
First, subtract 2x from both sides
22=3x-20Then add 20 to both sides
42=3xThen divide by 3 to both sides
14=x

2(14)+22=5(14)-2050=50Use the associative property of addition to write an equivalent expression for (x+17) + y
An equivalent expression is
Answer:
x + (y + 17)
Step-by-step explanation:
The associative property of addition is characterized by altering the order of operations by putting brackets in a different place. The answer will always be the same. Just the order is different.
So one possibility and the one you are likely expected to give is
x + (y + 17)
That means that if 17 and y can be added by giving y a value, then they will be done first.
Then you add z to the result if it has been given a value.
The answer you are expected to give is x + (y + 17)
