Breaking down:
$\frac{3}{15} = \frac{1}{5}$
${w}^{6} \div {w}^{2} = {w}^{4}$
${v}^{5} \div v = {v}^{4}$

Therefore,
$\frac{3 {w}^{6} {v}^{5} }{15 {w}^{2}v } \\ = \frac{{w}^{4} {v}^{4} }{5}$

Hope this helps. - M

A group of students held a fundraiser last year and raised $950 for charity. This year, they raised $1,045.

yuradex [85]

Answer:

the percent change in the amount the group raised is 10%.

Step-by-step explanation:

% change = (new value - old value) old value x 100 = (1,045 - 950)/950 x 100 = 95/950 x 100 = 0.1 x 100 = 10%

the triangle below is 45-45-90 determine the value of x and y your awsner must be in simplest radical form you cannot use sine c

Alexeev081 [22]

The diagram can be redrawn as,

The value of x and y can be determined as,

$\begin{gathered} \tan C=\frac{AB}{BC} \\ \tan 45^{\circ}=\frac{x}{7\sqrt[]{2}} \\ x=7\sqrt[]{2} \end{gathered}$ $\begin{gathered} \cos C=\frac{BC}{AC} \\ \cos 45^{\circ}=\frac{7\sqrt[]{2}}{y} \\ y=14 \end{gathered}$

Thus, option (D) is the correct solution.
