Two inequalities are equivalent if they have the same set of solutions.

x - 5 ≤ 6 - 5

x - 5 ≤ 1    |add 5 to both sides

Help pls I need answers ASAP
pishuonlain [190]

\tt Step-by-step~explanation:

To be able to solve this question, we need to know about the Pythagorean theorem: a² + b² = c². A and b represents the two sides that make the right angle, and C represents the hypotenuse, or the longest side, of the triangle.

\tt Step~1:

We know that the hypotenuse is the longest side of the triangle, so that means 9 is c. One side of the triangle is 6, and we have to solve for b. That means 6 is a. We can plug in our values to the formula like this:

\tt a^2+b^2=c^2\\6^2+b+2=9^2\\36+b^2=81

\tt Step~2:

Now that we have our equation down, we know what we have to do next: subtract 81 from 36 to get b².

\tt 81-36=\sqrt{45}

\Large\boxed{\tt Our~final~answer:~b=\sqrt{45} ~(simplified:3\sqrt{5}) }

Question Number 16 You are the head seamstress at a boutique that specializes in making prom dresses. You are supervising the co
antiseptic1488 [7]

This dress will be sold in the boutique for $6,716.25.

<h3><u>Price calculation</u></h3>

Given that a new style of dress will take 180 hours of work to complete, and twenty percent of this time is for beading, thirty-five percent of this time is for adding ruffles, and the remaining time is divided equally between embroidery and sewing, and when pricing this style, hourly labor and material costs are $40 for beading, $35 for ruffles, $20 for embroidery, and $18 for sewing, and the dress is then sold in the showroom for 25% more than the cost of labor and materials, To determine how much this dress will sell for in the boutique, the following calculation must be made:

  • (((180 x 0.25) x 40) + ((180 x 0.35) x 35) + ((180 x 0.20) x 20) + ((180 x 0.20) x 18)) x 1.25 = X
  • ((45 x 40) + (63 x 35) + (36 x 20) + (36 x 18)) x 1.25 = X
  • (1800 + 2205 + 720 + 648) x 1.25 = X
  • 5373 x 1.25 = X
  • 6,716.25 = X

Therefore, this dress will be sold in the boutique for $6,716.25.
