Jasim has invested 600 dinars in a business at the rate of 4 % for 3 years. Find his

Marat540 [252]

Answer:

1) Simple interest is 72 dinars

2) Total amount after 3 years is 672 dinars.

Step-by-step explanation:

Principal Amount P = 600 dinars

Interest Rate= 4% = 0.04

Time = 3 years

i) Simple Interest

The formula used to calculate interest is $I=P\times r \times t$

Putting values and finding interest

$I=P\times r \times t\\I=600\times 0.04 \times 3\\I=72$

So, simple interest is 72 dinars

ii) Total amount after 3 years

The formula to calculate total amount is: $A=P(1+rt)$

Putting values and finding future amount A

$A=P(1+rt)\\A=600(1+(0.04*3))\\A=600(1+0.12)\\A=600(1.12)\\A=672$

So, Total amount after 3 years is 672 dinars.

Answer:

Step-by-step explanation:

3x + 2y = 24

6x + 2y = 30

Multiply the first equation by -2.

-6x - 4y = -48

Add to the second

-2y = -18

y = 9

Plug back in the first.

3x + 2(9) = 24

3x = 6

x = 2

Angle A and angle b are complementary angles. If m angle A=4x+6 and m angle b=4x-4 then find the measure of angle A

Pavlova-9 [17]

Answer:

Step-by-step explanation:

∠A and∠B being complementary means m∠A+m∠B=90°

m∠A = (4x+6)° and m∠B = (4x+4)°

so:

4x+6 + 4x+4 = 90

8x + 10 = 90

8x = 80

x = 10

m∠A = (4•10+6)° = 46°
