Order of Operations

emmasim [6.3K]

Given:

$4 + 9 + 16 \div 4 - 8 -3 \times 5$

To find:

The number of possible solutions, if the Order of Operations did not exist.

Solution:

We have,

$4 + 9 + 16 \div 4 - 8 -3 \times 5$

Now,

Case 1:

$[4 + 9 + 16] \div [4 - 8 -(3 \times 5)]=29\div (4 - 8 -15)$

$4 + 9 + 16 \div 4 - 8 -(3 \times 5)=-\dfrac{29}{19}$

Case 2:

$[4 + 9 + 16] \div (4 - 8 -3) \times 5=29\div (-7\times 5)$

$4 + 9 + 16 \div (4 - 8 -3) \times 5=-\dfrac{29}{35}$

Case 3:

$4 + 9 + (16 \div 4) - 8 -(3 \times 5)=4+9+4-8-15$

$4 + 9 + (16 \div 4) - 8 -(3 \times 5)=-6$

Many more possibilities are there.

Therefore, there are more than 3 possible solutions.

Answer:

143 calories

Step-by-step explanation:

We can use a ratio to solve

110 calories x calories

----------------- = ---------------

28.4 grams 36.92 grams

Using cross products

110* 36.92 = 28.4 * x

Divide each side by 28.4

110*36.92 / 28.4 = x

143 calories = x

Anastasy [175]

Answer:

Mean: 10

Median: 9

Mode: 9

Range: 17

Step-by-step explanation:

Mean is adding all the numbers together then *divide by the number of numbers you added:

4 + 4 + 6 + 7 + 9 + 9 + 9 + 10 + 14 + 17 + 21 = 110

110 / 11 = 10

Median is the middle number: 9

The number that appears the most often is the mode: 9

The range is the difference between the lowest and highest number:

21 - 4 = 17

vekshin1

Answer:

985.15mg

Step-by-step explanation:

Calculation for how many milligrams of the drug should he receive every 12 hours

First step is to calculate the weight in kg

255 lbs = 255/2.2 = 115.9 kg

Second step is multiply mg/kg in order to get total medicine per day

Dose per day=115.9kg × 17 mg

Dose per day= 1,970.3

Third step is to calculate how many milligrams of the drug should he receive by dividing the day dose by 2

Dose milligrams=1,970.3/2

Dose milligrams=985.15mg

Therefore how many milligrams of the drug should he receive every 12 hours will be 985.15mg
