If the APR of a savings account is 5.3% and interest is compounded quarterly,

Mathematics
1 answer:
CaHeK987 [17]3 years ago
4 0

Answer:

5.41%

Step-by-step explanation:

Let us assume that x amount is invested in a savings account with APR 5.3% and the interest is compounded quarterly.

Then the quarterly percentage rate is \frac{5.3}{4} =1.325%.

Therefore, the amount x will become after one year  

x[1+ \frac{1.325}{100} ]^{4}  = 1.0541x

Therefore, the annual percentage yeild will be \frac{(1.0541x - x) \times 100}{x} % = 5.41%. ( Answer )

How to make a decimal a mixed number​
lianna [129]

Answer:Step 1: Write down the decimal divided by 1, like this: decimal1

Step 2: Multiply both top and bottom by 10 for every number after the decimal point. (For example, if there are two numbers after the decimal point, then use 100, if there are three then use 1000, etc.)

Step 3: Simplify (or reduce) the fraction

Example: Convert 0.75 to a fraction

Step 1: Write down 0.75 divided by 1:

0.751

Step 2: Multiply both top and bottom by 100 (because there are 2 digits after the decimal point so that is 10×10=100):

× 100

right over arrow

0.751 = 75100

right under arrow

× 100

(Do you see how it turns the top number

into a whole number?)

Step 3: Simplify the fraction (this took me two steps):

÷5 ÷ 5

right over arrow right over arrow

75100 = 1520 = 34

right under arrow right under arrow

÷5 ÷ 5

Answer = 34

1. A quadrilateral has vertices (5, 3) (5,-1) (-1,3) and (-1,-1). What special quadrilateral is formed by connecting the midpoin
antiseptic1488 [7]

Answer:

1. Kite,

2. Kite.

Step-by-step explanation:

1. The quadrilateral form will have 2 equal  pairs of adjacent sides which is a kite.

2. Find the slope and length of the sides:-

slopes (9-6)/ 0-3) = -1

(6-1) / (3-0) = 5/3

(6-1) / (-3-0) = -5/3

(9-6)/(3) = 1

Lengths = sqrt(9 + 9) = sqrt18

sqrt(25 + 9) = sqrt34

sqrt (25 + 9) = sqrt34

sqrt (9 + 9) = sqrt18.

This is another kite.

sergejj [24]

Answer:

29

Step-by-step explanation:

conjugate of a+ib=a-ib

conjugate of 2-5i=2+5i

(2+5i)(2-5i)=2²-(5i)²=4-25i²=4-25(-1)=4+25=29

4 people went to the movies. Each person spent $9.50 on a ticket and had the same amount of money leftover. They originally had
solong [7]

$2.50 was left for each person.

4(9.50) + x = 48

38 + x = 48

subtract 38 on both sides

x = 10

10$ was left in total by all 4 people

10/4 = 2.50

$2.50 was left over for each person
