Anettt [7]
<span>The was a 30% decrease in area. You started with 40 sq ft and ended up with 28 sq ft. So you lost 40 - 28 = 12 sq ft. Now you need to figure out what percentage of 40 is 12. For that you just simply divide 12 / 40 = 0.30 And to convert 0.30 from a decimal to a percentage, just multiply by 100. 0.30 * 100 = 30%</span>

almond37 [142]

Answer:

Option OD - 9

Step-by-step explanation:

Given : On the cardiac ward of a local hospital, there are 7 nursing assistants. The seven assistants have 7, 8, 5, 9, 10, 10, and 14 patients, respectively, that they assist.

To find : What is the average number of patients per nursing assistant?

Solution :

The average number of patients per nursing assistant is given by the division of sum of number of patients by total number of nursing.

So, \text{Average} =\frac{\text{Sum of patients}}{\text{Number of assistants}}

\text{Average} =\frac{7+8+5+9+10+10+14}{7}

\text{Average} =\frac{63}{7}

\text{Average} =9

Therefore, The average number of patients per nursing assistant is 9.

So, Option OD is correct.

Sin 7A = cos 3A, then m∠A is what?
lbvjy [14]

Answer:

m∠A = 9°

Step-by-step explanation:

\sin 7A =  \cos 3A \\  \\ \sin 7A =  \sin(90 \degree -  3A) \\  \\ 7A =  90 \degree -  3A\\  \\ 7A  + 3A=  90 \degree  \\  \\ 10A=  90 \degree  \\  \\ A =  \frac{90 \degree}{10}  \\  \\  m \angle A =9 \degree
