Answer:

Tiny magnets attached to the flies made it possible to upset the insects by zapping them in mid-flight with brief magnetic pulses, forcing them to roll like out-of-control aircraft. But the flies did not stay out of control for long.

A man borrowed money at a bank $1400 at the rate o 3% for 3 years. a) Find the simple interest b) Find th total money repaid aft

zhannawk [14.2K]

Answer:

a) The simple interest is $126.

b) The total money repaid after 3 years is $1526.

Step-by-step explanation:

A man borrowed money at a bank $1400 at the rate o 3% for 3 years.

a) Find the simple interest

$\longrightarrow{\sf{\red{S.I = \dfrac{PRT}{100}}}}$

→ S.I = Simple Interest
→ P = Principal
→ R = Rate
→ T = Time

Substituting all the given values in the formula to find the Simple Interest :

$\longrightarrow{\sf{S.I = \dfrac{PRT}{100}}}$

$\longrightarrow{\sf{S.I = \dfrac{P \times R \times T}{100}}}$

$\longrightarrow{\sf{S.I = \dfrac{1400 \times 3 \times 3}{100}}}$

$\longrightarrow{\sf{S.I = \dfrac{14 \cancel{00}\times 3 \times 3}{1 \cancel{00}}}}$

$\longrightarrow{\sf{S.I = 14 \times 3 \times 3}}$

$\longrightarrow{\sf{S.I = 42 \times 3}}$

$\longrightarrow{\sf{S.I = 126}}$

$\star{\underline{\boxed{\pmb{\sf{S.I = \$126}}}}}$

Hence, the simple interest is $126.

━━━━━━━━━━━━━━━━

b) Find the total money repaid after 3 years

$\dashrightarrow{\sf{\pink{A = P + S.I }}}$

→ A = Amount
→ P = Principal
→ S.I = Simple Interest

Substituting all the given values in the formula to find the Amount :

$\dashrightarrow{\sf{A = P + S.I }}$

$\dashrightarrow{\sf{A = 1400 + 126 }}$

$\dashrightarrow{\sf{A = 1526}}$

$\star{\underline{\boxed{\pmb{\sf{A = \$1526}}}}}$

Hence, the total money repaid after 3 years is $1526.

<span>There are three major groups of mammals, categorized on the basis of their method of reproduction. Monotremes lay eggs to have children instead of having the mother bear them. The second type of mammal is the marsupial, which are non-placental animals who carry their young in their pouches. Eutherians are the third group who are placental mammals.</span>
