Determine the first expression to evaluate in each problem (3+3)+6÷3+6

Answers

To know what to do first in a math problem we look to order of operations... PEMDAS stands for parentheses, exponents, multiplication, division, addition, and subtraction. So to begin we look for parentheses... do we have any? Why, yes, yes we do. Let's work!

(3+3) + 6 / 3 + 6 =

Add 3+3 in the parentheses. Since there is nothing else, the parentheses can go away.

6 + 6 / 3 + 6 =

Now, any exponents? Nope... Multiplication? Nope... division? Yes! Let's go!

6 + 2 + 6 =

Now all we have left is addition... Go for it!

8 + 6 = 14

Done!

Time for the Order of Operations!
PEMDAS, its easy dont worry!
P for Parenthesis
E for Exponents
M/D for Multiplication/Division
A/S for Addition/Subtraction
we should always follow the order of operations!

(3+3)+6÷3+6
1st step: We've got parenthesis:
(3+3)=(6) done
2nd step: Check for exponents, Looks like we dont have them!
3rd step: M/D? no multiplication, But we do have division.
(6)+6 ÷ 3 + 6
6 + 2 + 6
4th and last step: Finally, we are going to end this!
A/S? Yes!!!! Addition, No Subtraction!
6 + 2 + 6 = 14

Final Answer: 14

If you are really clever, you can convert between units used. If you want toknow how fast the ball is travelling in the above question in km/hr we must
first convert metres to km and seconds into hours.
Metres to kilometres = 22,metres ÷ 1000 (1000 metres in a kilometre)
.022 km
Seconds to hours = 0.6s+ 3600 (60 seconds in a minute x 60 minutes in an hour)
60min
⇒ Calculate the speed of the ball in km/hr (remember km + hours)
⇒ An aeroplane travels from Brisbane to Melbourne in 2 hours. The
distance travelled is 1700km. What was its speed in km/hr and m/s?
⇒ A student walks 8km in 2 hours. What was its speed in km/hr and
m/s?

Answers

Let's calculate the speed in km/hr and m/s for both scenarios:

**Scenario 1: Ball Travel**

You've already provided the conversions for meters to kilometers and seconds to hours, which are correct.

Distance (in km) = 22 meters / 1000 = 0.022 km
Time (in hours) = 0.6 seconds / 3600 = 0.000167 hours

Now, calculate the speed:
Speed (in km/hr) = Distance / Time = 0.022 km / 0.000167 hours ≈ 131.74 km/hr

**Scenario 2: Aeroplane Travel**

Distance (in km) = 1700 km
Time (in hours) = 2 hours

Now, calculate the speed:
Speed (in km/hr) = Distance / Time = 1700 km / 2 hours = 850 km/hr

To convert this speed to m/s, remember that 1 km/hr is approximately 0.27778 m/s:
Speed (in m/s) ≈ 850 km/hr × 0.27778 m/s/km/hr ≈ 236.11 m/s

**Scenario 3: Student Walking**

Distance (in km) = 8 km
Time (in hours) = 2 hours

Now, calculate the speed:
Speed (in km/hr) = Distance / Time = 8 km / 2 hours = 4 km/hr

To convert this speed to m/s:
Speed (in m/s) ≈ 4 km/hr × 0.27778 m/s/km/hr ≈ 1.1111 m/s

So, in summary:

**Scenario 1: Ball Travel**
- Speed in km/hr: Approximately 131.74 km/hr

**Scenario 2: Aeroplane Travel**
- Speed in km/hr: 850 km/hr
- Speed in m/s: Approximately 236.11 m/s

**Scenario 3: Student Walking**
- Speed in km/hr: 4 km/hr
- Speed in m/s: Approximately 1.1111 m/s
