2300 is invested in 4 years at 5% per year simple interest work out the total interest

460

Step-by-step explanation:

I=P x r x t

P is the principal amount, $2300.00.

r is the interest rate, 5% per year, or in decimal form, 5/100=0.05.

t is the time involved, 4year(s) time periods.

So, t is 4year time periods.

To find the simple interest, we multiply 2300 × 0.05 × 4 to get that:

The interest is: $460.00

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°
