Answer:

- 1/2

Step-by-step explanation:

turn 2/5 to have the same denominator as 10

2 ( 2 ) = 4

5 ( 2 ) = 10

4/10 - 9/10

= -5/10

simplify

-5/10 = -1/2

hope this helps

Change mixed numbers to improper fractions. Then change division to multiplication by the reciprocal.
1 1/2 divided by 3/5=
(3/2) * (5/3) = 5/2 = 2 1/2
#3
(5/9) divided by (5/3)
(5/9) * (3/5) =3/9 = 1/3

Can someone help me with this problem ​
Alex_Xolod [135]

Answer:

<h2>A = 20</h2><h2>P = 6√10</h2>

Step-by-step explanation:

The formula of a distance between two points:

d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

A(-3, 0) , B(3, 2)

AB=\sqrt{(3-(-3))^2+(2-0)^2}=\sqrt{6^2+2^2}=\sqrt{36+4}=\sqrt{40}=\sqrt{4\cdot10}=\sqrt4\cdot\sqrt{10}=2\sqrt{10}

A(-3, 0), D(-2, -3)

AD=\sqrt{(-2-(-3))^2+(-3-0)^2}=\sqrt{1^2+(-3)^2}=\sqrt{1+9}=\sqrt{10}

AB = CD and AD = BC

The area of a rectangle:

A=(AB)(AD)

Substitute:

A=(2\sqrt{10})(\sqrt{10})=(2)(10)=20

The perimeter of a rectangle:

P=2(AB+AD)

Substitute:

P=2(2\sqrt{10}+\sqrt{10})=2(3\sqrt{10})=6\sqrt{10}

Consider a student loan of 25000 at a fixed APR of 6% for 15 years calculate the monthly payment
hram777 [196]

<u>Answer: </u>

Monthly payments of student loan 25000 at fixed APR of 6% for 15 years is 264 units of money approximately

<u>Solution: </u>

Given that  

Amount of student loan P = 25000

APR = R = 6%

Duration = T = 15 years  

First let’s calculate interest on loan.

Interest = \frac{P \times R \times T}{100} = \frac{25000 \times 6 \times 15}{100} = 22500

Total amount needs to pay back = Loan amount + interest = 25000 + 22500 = 47500

Duration in which amount needs to be pay back = 15 years = 15 \times 12 = 180 months

Monthly payment = Total amount needs to pay back / duration in months  

= \frac{47500}{180}

= 263.88.

Hence monthly payments of student loan 25000 at fixed APR of 6% for 15 years is 263.888 approx 264 units of money.
