scZoUnD [109]4 years ago
5 0

Answer:

A. 7√3 in

Step-by-step explanation:

We first have to draw out the altitude on the triangle. When we do so, we should see that we will get 2 congruent 30-60-90 triangles. From there, our <em>h</em> height is <em>x</em> and we use tan∅ to solve:

tan60° = x/7

x = 7tan60°

x = 7√3

Solve the inequality and graph the solution. −0.8b + 2.3 ≥ 8.7
zlopas [31]

The solution of the inequality is -8 ≥ b, and the correct graph is the one in option D.

"number line with a closed circle plotted at negative eight and arrow pointing left."

<h3>How to solve the inequality?</h3>

Here we have the inequality:

-0.8*b + 2.3  ≥ 8.7

And we want to solve this, to do so, we need to isolate the variable b in one of the sides of the inequality.

-0.8*b + 2.3  ≥ 8.7

2.3 - 8.7 ≥ 0.8*b

-6.4  ≥ 0.8*b

-6.4/0.8  ≥ b

-8 ≥ b

So the solution is the set of all numbers equal to or smaller than -8, then the correct graph will be the one described by D.
