Which of the following statements describes the process for solving 4x ≥ -24?
dezoksy [38]
Divide both sides of the inequality by 4 but don’t flip the symbol.

You only flip the inequality symbol if you divide by a negative number.

If you’re solving for x (which you are), you want to get x by itself. The only way to do that is to divide by 4.

Find f(1/3) if f(n) =3n
hichkok12 [17]

Answer:

f(1/3) = 1

Step-by-step explanation:

Plug 1/3 in for n

f(1/3) = 3(1/3)

Now simplify

f(1/3) = 1                 {   3(1/3) = (3/1)(1/3) = 3/3 = 1   }

The recommended angle for a wheelchair ramp is 5 degrees. If the rise of the ramp to go up the steps is 5 feet, find the horizon
dybincka [34]

Answer:

57.2\ ft

Step-by-step explanation:

we know that

The formula of slope is "rise over run", where the "rise" (means change in y, up or down) and the "run" (means change in x, left or right)

In this problem

The tangent of angle of 5 degrees is equal to the quotient of "rise over run"

Let

y ----> the rise of the ramp

x ----> the run of the ramp

tan(5^o)=\frac{y}{x}

we have

y=5\ ft

substitute and solve for x

tan(5^o)=\frac{5}{x}

x=\frac{5}{tan(5^o)}

x=57.2\ ft

What type of triangle has exactly two acute triangles ​
Sveta_85 [38]

Answer: A right triangle.

Step-by-step explanation:

This is because an acute triangle would have all of its three sides acute while an obtuse one would have two acute angles as well, but also an obtuse one. If the question is specifically asking for a triangle with exactly two acute angles, a right triangle would be the answer.

A sporting goods store displays the following sale sign. What percent off is the sale
victus00 [196]

Answer:

The sale is 5% off.

Step-by-step explanation:

  • $25 regular price.
  • $18.75 sale price.

You need to find the percentage that deducts $1.25 from the regular price. I start with 5% and work my way up from there until I find the answer.

So, <em>5</em><em>%</em><em> </em><em>of </em><em>2</em><em>5</em><em> </em><em>=</em><em> </em><em>?</em>

5% * 25 = 1.25

You needed $1.25, 5% gives you that.

Therefore, the answer is 5%.
