Parentheses \\ Exponents \\ Multiplication \\ Division \\ Addition \\ Subtraction

<em>Parentheses is first. </em>

6+9\div3

Division comes before addition.

9 \div 3 = 3 \\ 6+3 = \bf 9

Your new equation is:

674 \div (9)

Divide

674 \div 9 = 74.89

Your answer is <u>74.89</u>

A worker is paid $18.50 per hour for the first 40 hours of work and time and a half for any overtime exceeding 40 hours per week
Lisa [10]

Answer:

The worker's pay is $795.50.

Step-by-step explanation:

The worker gets paid $18.50 for the first 40 hours of work. The worker works 46 hours. 18.50 • 40 = 740. He worked 6 hours overtime. $18.50 ÷ 2 = $9.25. $9.25 • 6 = $55.50.

$740 + $55.50= $795.50

Find cot theta. (-6,-3sqrt(5)
cupoosta [38]

0  Pretend that is theta XD


cot 0 = \frac{1}{tan0}


Find tan 0.

tan 0 = \frac{y}{x}

tan 0 = \frac{-3\sqrt{5}}{-6}

tan 0 = \frac{\sqrt{5}}{2}


cot 0 = \frac{1}{tan0}

cot 0 = \frac{1}{\frac{\sqrt{5} }{2} }    

Multiply 2/√5 to the numerator and the denominator (or multiply the reciprocal of the denominator to the top and bottom of the fraction)

cot 0 = \frac{1}{\frac{\sqrt{5}}{2} } (\frac{\frac{2}{\sqrt{5}} }{\frac{2}{\sqrt{5}}} )

cot 0 = \frac{2}{\sqrt{5}}  

Multiply √5 to the numerator and the denominator

cot 0 = \frac{2}{\sqrt{5}} (\frac{\sqrt{5} }{\sqrt{5} })

cot 0 = \frac{2\sqrt{5}}{5}

A warehouse has a height of 8\frac{1}{2}8 2 1 ​ meters, length of 120120 meters, and width of 20\frac{3}{10}20 10 3 ​ meters
vovangra [49]

Answer:

10,353m³

Step-by-step explanation:

<em>We can look for the volume of the warehouse since we are not told what to look for</em>

Volume of the warehouse = length * width * height

Given

Length  = 120m

Width = 20 3/10 = 203/20 m

Height = 8 1/2m = 17/2 m

Volume of the warehouse = 120 * 203/20 * 17/2

Volume of the warehouse = 6 * 203 * 17/2

Volume of the warehouse = 3 * 203 * 17

Volume of the warehouse = 10,353 cubic metres

Hence the volume of the warehouse is 10,353m³

julsineya [31]

Answer:

Varies - possibly not enough information

Step-by-step explanation:

How many doses per day?

Do you only need to know the amount of oz. for "today"?

Does this need to be expressed in decimal form?

If the patient is ordered to take 2- 2/3 oz. per day, you have your answer.

Decimal form: 2-2/3 = 8/3 = 2.667 oz.
