The two inequalities that represents the constraints for the art studio classes per week are:

x + 1.5y = 40

35(x + y)  > 1,000

<h3>What two inequalities represent the constraints?</h3>

Here are inequalities signs and what they mean:

> means greater than

< means less than

≥ means greater than or equal to

≤ less than or equal to

= means equal to

The inequality that represents the total hoursthe art studio is open would be an equal to sign. This is because the store is open for a maximum of 40 hours.

The inequality that represents the total earnings would be represented with a greater than sign because the studio earns more than $1000 weekly.

Find the length of AC Use that length to find the length of
Gekata [30.6K]

Answer:

1. AC = 5 cm

2. CD = 10.7 cm

Step-by-step explanation:

Looking at the left triangle, we see that AC is the side "opposite" of the angle given and AB is the "hypotenuse".

Which trigonometric ratio relates "opposite" to "hypotenuse"?

<em>Yes, that's SINE.</em>

<em />

So we can write:

Sin(30)=\frac{AC}{10}\\AC=10*Sin(30)

We know from 30-60-90 triangle, Sin(30) = 0.5, so we have:

AC=10*Sin(30)\\AC=10*0.5\\AC=5

Thus,

AC = 5 cm

Now, looking at right side triangle, we know AC, side "opposite" and we want to find CD, side "adjacent". Which trig ratio relates these 2 sides?

<em>Yes, that's tan!</em>

Thus we can write:

Tan(25)=\frac{5}{CD}\\CD=\frac{5}{Tan(25)}

Now using calculator, we get our answer to be:

CD = \frac{5}{Tan(25)}=10.7

So

CD = 10.7 cm
