C. Less than $30,000

D. More than $30,000

Answer:

A. At least $30,000

2x + $10,000 ≥ $70,000 ;

Where x salary of an employee ;

Phrase which describes the employee's salary, x

2x + 10000 ≥ 70000

2x ≥ 70000 - 10000

Express the edge length of a cube as a function of the cube's diagonal length d. Then express the surface area & volume of t
padilas [110]
If we consider "a" as the edge length, and "D" the cube's diagonal, we have that the square cube's diagonal is equal to the edge length's square plus the side diagonal (d) square (Pythagoras theorem)

a² + d² = D²

And since:
d² = a² + a²

Clearing a, we have:
a² = D²-d²
<span>a² = D²-2a²
</span><span>3a² = D²
</span>a = √(<span>D²/3)
</span>
Surface area is equal to 6·a², so the surface area will be 6·(D²/3) = 2D²

The volume is a³, so the volume will be √(D²/3)³ = √(D^{6}<span>/3</span>³<span>) = D</span>³/√27

If you have 16 cups of sugar , 2 cups of sugar for every batch of cookies , but you have to save 6 cups of sugar for something e
sesenic [268]
The first step we want to take here is to subtract 6 cups of sugar since we'll need it for something else, leaving us with 10 cups of sugar. It takes 2 cups of sugar for every batch of cookies, so you're going to divide 10 by 2. Luckily, 2 is a multiple of 10 so it's a whole number. By dividing, we get 5. So, we can make 5 batches of cookies while still saving 6 cups of sugar for something else.
