What is the missing length

Zina [86]

Answer:

c = 12

Step-by-step explanation:

$a^{2} + b^{2} = c^{2}$

$7.2^{2} + 9.6^{2} = c^{2}$

51.84 + 92.16 = $c^{2}$

144 = $c^{2}$

$\sqrt{144}$ = c

12 = c

kupik [55]

Answer:

The number of FTE needed to be hired to cover the additional procedures per 7.5 day work is:

= 1.

Step-by-step explanation:

a) Data and Calculations:

Endoscopies EP Studies Total

Projected number of studies 60 5 65

Time in minutes for per study 5 15

Total time required (in minutes) 300 75 375

Full-time Employee (FTE) works 7.5-hour day or 450 minutes (7.5 * 60) per day.

b)The number of full-time employees (FTE) needed to be hired to cover the additional procedures per 7.5-day work is 1. The FTE has 450 minutes available for the additional procedures. She will only require 375 minutes. Therefore, she has extra (idle) time of 75 (450 - 375) minutes per workday.

Paul bought a circular rug for his living room. The rug has a diameter of 11 feet. About how much of Paul's living room will be

fenix001 [56]

Answer:

The rug has covered approximately 95 square feet of the living room.

Step-by-step explanation:

Given:

Diameter of rug = 11 feet

We need to find the area covered in living room by the rug.

Solution:

Diameter of rug = 11 feet

Radius is half of the diameter.

Radius of the rug = $\frac{11}{2}=5.5\ ft$

Now it has been given that rug is in circular shape.

So we will find the area of the rug using Area of circle formula which is given by π times square of the radius.

Framing in equation form we get;

area of the rug = $\pi r^2 = 94.99\ ft^2 \approx 95\ ft^2$

Hence The rug has covered approximately 95 square feet of the living room.
