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.

Can anyone help me plzzzzz /deltamath

irakobra [83]

ANSWER: square root of 10

Rule: Pythagorean Theorem (a^2 + b^2 = c^2; side^2 + second side^2 = hypotenuse^2)

(substitute the missing side w/ a variable)
x^2 + 7^2 = (sqrt. 59)^2
x^2 + 49 = 59
x^2 = 10
x = sqrt. 10

The endurance of both track athletes and gymnasts is recorded in terms of maximum volume of oxygen and is measured in milliliter

Olin [163]

The mean of the track athletes is given by
$\frac{89.2+45.3+89.1+57.3+61.5+80.1+47.2}{7}=67.1$

The mean of the gymnasts is given by
$\frac{72.1+78.5+66.2+47.3+63.1+89.3+65.3}{7}=68.8$

The difference in mean is given by
$68.8-67.1=1.73$ (rounded to one decimal place)
