Answer:

The answer is 27.5 units.

Step-by-step explanation:

The shape looks like trapezoid which corners are at below points:

A(-3,3)

B(-3,-4)

C(2,-2)

D(2,2)

To calculate surface of this trapezoid, we can use the formula below:

S=(CD+AB)*h/2

Where:

CD=4 unit

AB=7 unit

h=5 unit

S=(4+7)*5/2=27.5

8_murik_8 [283]

Answer: $45451

Step-by-step explanation:

We would apply the formula for determining compound interest which is expressed as

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

Where

A = total amount in the account at the end of t years

r represents the interest rate.

n represents the periodic interval at which it was compounded.

P represents the principal or initial amount deposited

From the information given,

P = 25000

r = 3% = 3/100 = 0.03

n = 4 because it was compounded 4 times in a year.

t = 20 years

Therefore,

A = 25000(1+0.03/4)^4 × 20

A = 25000(1+0.0075)^80

A = 25000(1.0075)^80

A = $45451

When 1760 is divided into 14 equal parts, the remainder is 10. What is a correct way to write the quotient?
Monica [59]

I believe the answer is,

As an improper fraction

(numerator larger than denominator):

1,760/14 = 880/7

As a mixed number (mixed fraction)

(a whole number and a proper fraction):

1,760/14 = 125 5/7

As a decimal number:

1,760/14 ≈ 125.71

As a percentage:

1,760/14 ≈ 12,571.43%
