Each vertical cross-section of the triangular prism shown below is an isosceles triangle. 4 4 5 5 s s What is the slant height, s ss, of the triangular prism? Round your answer to the nearest tenth. The slant height is units. Hint #11 / 2 We see that s ss is the hypotenuse of a right triangle. One leg of the right triangle is 5 55. The other leg is 2 22, which is half the base of the isosceles triangle. 5 5 s s 4 4 2 2 2 2 From the Pythagorean Theorem, we have: 2 2 + 5 2 = s 2 4 + 25 = s 2 29 = s 2 29 = s 5.385 ≈ s 2 2 +5 2 4+25 29 29 ​ 5.385 ​ =s 2 =s 2 =s 2 =s ≈s ​

Paula makes stained-glass windows and sells them to boutique stores. if her costs total $12,000 per year plus $4 per window for the frame. how many windows must she produce to earn a profit of at least $48,000 in one year if she sells the windows for $28 each? 1. define a variable for the situation. 2. write an inequality that represents her profit. note: revenue is money coming in. cost is money going out. profit is the difference between the revenue and the cost. in other words: revenue - costs profit 3.using words, describe how many windows she must sell to have a profit of at least $48,000.
