A medical office is replacing their existing flooring with carpeting in the waiting and office areas and laminate flooring in th

PSYCHO15rus [73]

Area of 1 exam room = 10 ft. × 10 ft. = 100 ft.²
Area of 10 exam room = 100 ft.² × 10 = 1000 ft.²

Area of waiting room = 20 ft. × 15 ft. = 300 ft.²

Area of office area = 25 ft. × 20 ft. = 500 ft.²

Now,
Total area of the hospital to be replaced = 1000 ft.² + 300 ft.² + 500 ft.² = 1800 ft.²

Mrs. Carson pays Kristen $48 for babysitting six hours and mr.vanquez pays her $67.50 for babysitting nine hours who pays Kriste

brilliants [131]

Mrs Carson gives the better deal, this is becuase when i set up an inequality 48/6 and 67.50/9, i divided 48 by 2 then added 24 to 48 so i could get them both so i can see what they give, so Mrs Carson gives 72 dollars every 9 hours and thats better than 67.50.

The triangle below is equilateral. Find the length of side x to the nearest tenth.

Gemiola [76]

Answer:

$\sqrt{\frac{15}{2} }$ or 2.738

Step-by-step explanation:

Let’s just look at the triangle on the top with the $\sqrt{10}$ on the top and x on the bottom. (Basically the top half to the equilateral triangle)

There is a small square in the bottom right corner, which indicates that this triangle is a right triangle. This means that we can use the Pythagorean Theorem: $a^{2} +b^{2} =c^{2}$

We know that \sqrt{10} is our hypotenuse, and therefore our c in our equation. Let’s say that x=a in our equation. Therefore we are left to find b. However, b is half the length of the side of the original equilateral triangle. An equilateral triangle means that all three sides are the same length. Therefore our side would also be \sqrt{10} units long. However we know that b is half of that value, so b= $\frac{1}{2}(\sqrt{10})$ or $\frac{\sqrt{10} }{2}$
