Answer:

D) x ≥ 3750

Step-by-step explanation:

For this situation, we begin with our expression, 350+0.12x.  Since the salesperson wants to earn at least $800, this means she could earn more as well.  This is the symbol greater than or equal to:

350+0.12x ≥ 800

Subtract 350 from each side:

350+0.12x-350 ≥ 800-350

0.12x ≥ 450

Divide both sides by 0.12:

0.12x/0.12 ≥ 450/0.12

x ≥ 3750

Answer:

The correct option is D.

Step-by-step explanation:

It is given that a salesperson earns $350 per week plus 12% of her weekly sales.

Let x be the weekly sales.

The expression representing her earnings is

350+0.12x

The sale necessary for the salesperson to earn at least $800 in one week.

350+0.12x\geq 800

Subtract 350 from both sides.

350+0.12x-350\geq 800-350

0.12x\geq 450

Divide both sides by 0.12.

\frac{0.12x}{0.12}\geq \frac{450}{0.12}

x\geq 3750

Therefore, the correct option is D.

Law of sines: How many distinct triangles can be formed for which m∠A = 75°, a = 2, and b = 3? No triangles can be formed. One t
Vinvika [58]

We have been given angle A as 75 degrees and sides a = 2 and b = 3.

Using Sine rule, we can set up:

\frac{Sin(A)}{a}=\frac{Sin(B)}{b}

Upon substituting the given values of angle A, and sides a and b, we get:

\frac{Sin(75)}{2}=\frac{Sin(B)}{3}

Upon solving this equation for B, we get:

\Rightarrow 3Sin(75)=2Sin(B)\\  \Rightarrow Sin(B)=\frac{3Sin(75)}{2}\\  \Rightarrow Sin(B)=1.4488\\

Since we know that value of Sine cannot be more than 1. Hence there are no values possible for B.

Hence, the triangle is not possible. Therefore, first choice is correct.
