Since the perimeters are equal then:

(3x + 3) * 4 = (x + 8) * 5
12x + 12 = 5x + 40
7x = 28
x =4
Perimeter of square = (3*4 + 3) * 4 =
(12 + 3) * 4 = 60

Perimeter of pentagon = (4 + 8) * 5 =
(12) * 5 = 60

The answer is 60

You deposit $20,000 in an account that pays 7.77% annual interest. Find the balance after 2 years when the interest is compounde
zvonat [6]

Answer:

=$23,350.802

Step-by-step explanation:

Compound Interest (A)=P(1+r/n)^nt

Where,

P=principal=$20,000

r=Interest rate=7.77%=7.77/100

=0.0777

n=number of periods=12 month in a year

t=time=2 years

(A)=P(1+r/n)^nt

=$20,000(1+0.0777/12)^12×2

=$20,000(1+0.006475)^24

=$20,000(1.006475)^24

=$20,000(1.1675401)

=$23,350.802

Median is the middle value, if you have an even number of values in the data set, add the two middle numbers and divide that by two. If you have an odd number in the data set, it would be the middle number.

Upper quartile is the middle value of the upper half of numbers in the data set, The upper half of numbers are the numbers below the Median. Use same way as the median to find the value.

Minimum is the lowest number in the set.

 Maximum is the highest number in the set.

Lower quartile is the middle value of the lower half of numbers in the data set, The lower half of numbers are the numbers above the Median. Use same way as the median to find the value.

Rashid [163]

Answer:$6250

Step-by-step explanation:

selling price(sp)=12000

Original price(op)=?

sp+500=2 x op

12000+500=2 x op

12500=2 x op

Divide both sides by 2

12500/2=(2 x op)/2

6250=op

Therefore original price is $6250
