Answer:

<W=180 - (30+81)

<W=69°

Using Sine rule to evaluate x

x/sin30 = 19/sin69

x= 19sin30/sin69

x= 10.2m ( Nearest tenth)

Use a common denominator to determine weather the ratio forms a proportion?

frosja888 [35]

1/7 and 3/14......common denominator is 14

2/14 = 3/14
cross multiply
(14)(3) = (14)(2)
42 = 28...not correct...no, this does not form a proportion

little tip ** proportions are nothing but equivalent fractions and 1/7 does not equal 3/14...now if it would have been 1/7 and 2/14...then it would have been a proportion

Write an equation of the line through (-1,-5) having slope 2/3. give the answer in standard form.

jekas [21]

keeping in mind that standard form for a linear equation means

• all coefficients must be integers, no fractions

• only the constant on the right-hand-side

• all variables on the left-hand-side, sorted

• "x" must not have a negative coefficient

$\bf (\stackrel{x_1}{-1}~,~\stackrel{y_1}{-5})~\hspace{10em} \stackrel{slope}{m}\implies \cfrac{2}{3} \\\\\\ \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-\stackrel{y_1}{(-5)}=\stackrel{m}{\cfrac{2}{3}}[x-\stackrel{x_1}{(-1)}]\implies y+5=\cfrac{2}{3}(x+1)$

$\bf \stackrel{\textit{multiplying both sides by }\stackrel{LCD}{3}}{3(y+5)=3\left( \cfrac{2}{3}(x+1) \right)}\implies 3y+15 = 2(x+1) \implies 3y+15=2x+2 \\\\\\ 3y=2x-13\implies -2x+3y=-13\implies 2x-3y=13$

Tammy earns a base salary of $300 every week with an additional 9% commission on whatever she sells. What was Tammy's total pay

castortr0y [4]

Answer:

Tammy's total pay for the week is $588

Step-by-step explanation:

We are given the following in the question:

Tammy's salary = $300 every week

Percentage of commission on sales = 9%

Total sale during week = $3200

Commission earned =

$9\% \times 3200\\\\=\dfrac{9}{100}\times 3200\\\\=\$288$

Thus, Tammy's week salary =

Weekly salary + Commission on sales

= $=300 + 288\\=588\$$

Thus, Tammy's total pay for the week is $588 if she sold $3200 worth of products.
