The circle graph shows the percentage of time Jacob spent on homework in each subject last week.Time Spent on Homework12.5%25%ar

Goshia [24]

We are given a circle graph that shows the time spent on homework last week.

Jacob spent a total of 16 hours doing homework.

The time spent on doing science homework is given by

$\begin{gathered} t_{\text{science}}=25\%\: of\: 16 \\ t_{\text{science}}=\frac{25}{100}\: \times\: 16=4\: \text{hours} \end{gathered}$

The time spent on doing band practice is given by

$\begin{gathered} t_{\text{band}}=12.5\%\: of\: 16 \\ t_{\text{science}}=\frac{12.5}{100}\: \times\: 16=2\: \text{hours} \end{gathered}$

The difference between the time spent on science homework and band practice is

$difference=t_{\text{science}}-t_{\text{band}}=4-2=2\: \text{hours}$

Therefore, Jacob spent 2 more hours on science homework than band practice.

I don’t understand at all

mariarad [96]

A=1/2ab
Replace the variables with their value
15=1/2(3/2)b
Multiply 1/2 and 3/2
$\frac{1}{2} \times \frac{3}{2 } = \frac{3}{4}$
15=3/4b
Divide 3/4 on both sides
15/(3/4) is the same thing as
$\frac{15}{1 } \times \frac{3}{4} = \frac{45}{4}$
45/4=b
