Sophia and isabella get a reward of 117 dollars ina ratio of 1:8.What fraction of the reward does sophia get?

worty [1.4K]

Answer:

The amount of reward that Sophia receives is $\$13$

Step-by-step explanation:

Let

x------> amount of reward that Sophia receives

y-----> amount of reward that Isabella receives

we know that

$\frac{x}{y}=\frac{1}{8}$

$x=\frac{1}{8}y$ ------> equation A

$x+y=117$ -----> equation B

Substitute equation A in equation B

$\frac{1}{8}y+y=117$

$\frac{9}{8}y=117$

$y=117*8/9=\$104$

Find the value of x

$x=\frac{1}{8}(104)=\$13$

$1 invested for 1 Year at 7.2% compound semiannually

WITCHER [35]

Answer:

Sum = $1.073

Interest = $0.073

Step-by-step explanation:

Given that $1 is invested for one year at 7.2% interest which compounds semi-annually.

Semi-annual means there should be two equal intervals in a year i.e. 6 months interval.

Now, the semi-annual rate of interest is $\frac{7.2}{2} = 3.6$ %.

Therefore, the invested money will become $1\times [1 + \frac{3.6}{100} ]^{2}$

= $1.073

Therefore, the interest obtained will be $(1.073 - 1) = $0.073. ( Answer )
