Use the simple interest formula to find the unknown quantity.
jenyasd209 [6]
First, converting R percent to r a decimal
r = R/100 = 4%/100 = 0.04 per year,
then, solving our equation

t = 9 / ( 450 × 0.04 ) = 0.5
t = 0.5 years

The time required to
accumulate simple interest of $ 9.00
from a principal of $ 450.00
at an interest rate of 4% per year
<span>is 0.5 years (about 0 years 6 months).</span>

Samir harvest the peppers and pumpkins in his garden he picks 3 5/8 less peppers in the afternoon than in the evening if Samir p
tatuchka [14]
<h2>Hello!</h2>

The answer is:

Samir picks 7\frac{9}{8} Kg of peppers in the evening.

<h2>Why?</h2>

To solve this problem, we must remember the way to add or subtract mixed numbers.

We must remember the way of adding or subtracting fractions:

\frac{a}{b}+\frac{c}{d} =\frac{ad+bc}{bd}

Also, if we need to add or subtract mixed numbers with different denominators, we need to follow the next steps:

- Add or subtract the whole number part

- Add or subtract the fractional numbers.

- Put together both, whole number addition or subtraction result and the addition or subtraction of the fractional numbers.

So,

a\frac{b}{c}+d\frac{e}{f} =(a+d)\frac{bf+ce}{cf}

Now, if Samir picks 3 5/8 less peppers in the afternoon than in the evenning, and if he picks 4 3/6 peppers in the afternoon, so:

Let be x the number of peppers that he picks in the evening, so:

x-3\frac{5}{8}x=4\frac{3}{6}\\\\x=4\frac{3}{6}+3\frac{5}{8}

Then, simplifying we have:

x=4\frac{3}{6}+3\frac{5}{8}\\\\x=4\frac{3}{6}+3\frac{5}{8}=(4+3)\frac{24+30}{48}\\\\x=(4+3)\frac{24+30}{48}=7\frac{54}{48}=7\frac{9}{8}

So, Samir picks 7\frac{9}{8} Kg of peppers in the evening.

Have a nice day!
