Answer:

The amount we need to invest is 500 muggle money.

Step-by-step explanation:

Amount needle to study at Hogwarts = A = 800 muggle money

Principle amount that we need to invest = P

Duration of investment = T = 5 years

Rate if simple interest = R = 12%

Simple interest = S.I

A = S.I + P

$800=\frac{P\times 12\times 5}{100}+P$

$800=0.6P+P$

$800=1.6P$

P = $\frac{800}{1.6}=500$

The amount we need to invest is 500 muggle money.

Can you find the area and explain how you got the area

rewona [7]

Answer:

102cm^2 - hope this helps

Step-by-step explanation:

find the area of the rectangle first in the middle

which equals 6 x 13 = 78cm^2

then find the traingles on the side

(6 x 4) / 2 = 12

there are 2 traingles so it would be 12 + 12 = 24

so all together the area would be 78 + 24 = 102cm ^2

A chemist is mixing a 50% salt solution with an 18% salt solution to make 40 L of a new solution that will contain 30% salt. How

Karolina [17]

Answer:

See below

Step-by-step explanation:

Sum of ingredients = sum of final solution

.50 x where x = 50 percent amount then 40 - x = 18% amount

.50 x + .18(40 - x) = .30 ( 40 )

.50 x + 7.2 - .18x = 12

.32x = 4.8

x = 15 L of 50% 25 liters of 18%
