Asales person at apple earns $300 per week plus commission equal to 5%of her sales . this week her goal is th earn at $550. write and solve an inequality to find the amount of sales she must have to reach her goal

Let us say that:

S = total sales

Therefore the inequality equation in this case is:

300 + 0.05 S ≥ 550

Solving:

S ≥ 5,000

Therefore she must have a sales of at least $5,000 to have an earning of at least $550.

the transverse axis of a hyperbola is the line that contains the two vertices and the two focuses.

in this example (hyperbola of equation x^2/2 - y^2/4 = 1), the transverse axis is the  x-axis  . 

step-by-step explanation:

c.   x=2.4cm

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.
