By definition, we have:
Scientific notation, also called pattern or notation in exponential form, is a way of writing numbers that accommodate values too large (100000000000) or small (0.00000000001) to be written in a conventional manner.
A number written in scientific notation follows the following pattern:
The number m is called "mantissa" and e the "order of magnitude"
For this case we have the following number:
Using the definition we have:
Answer:
The number written in scientific notation is given by:
2.251 cm
2.349 cm
2.352 cm
2.295 cm
b. Convert the rounded measurement to meters. Write an equation to show your work.
a. The possible actual measurements are 2.251 cm, 2.349 cm and 2.295 cm.
b. Rounded measurement in meters is 0.023 meters
a. To determine which measurements could be the actual measurement of the rainfall, we need to consider how rounding works.
When rounding to the nearest tenth of a centimeter, any measurement with a hundredth digit of 5 or greater rounds up, and any measurement with a hundredth digit less than 5 rounds down.
Given that the rounded measurement is 2.3 cm, let's evaluate the measurements:
2.251 cm: Rounds down to 2.3 cm
2.349 cm: Rounds up to 2.3 cm
2.352 cm: Rounds up to 2.4 cm
2.295 cm: Rounds down to 2.3 cm
So, the possible actual measurements are 2.251 cm, 2.349 cm and 2.295 cm.
b. To convert the rounded measurement to meters, we need to divide it by 100, since there are 100 centimeters in a meter.
Rounded measurement: 2.3 cm
Conversion to meters: 2.3 cm / 100 = 0.023 meters
Equation: Rounded Measurement (in meters) = Rounded Measurement (in centimeters) / 100
Rounded Measurement (in meters) = 2.3 cm / 100
= 0.023 meters

Answer:
A.2.251 cm , 2.349 cm, 2.295 cm
B. 0.023 meters.
Step-by-step explanation:
Answer:
9/1
Step-by-step explanation:
$27 for 3 hours. To find the slope, it always has to be over 1 hour because it's a unit rate. 27/3 would be 9. It makes sense too because $9 per 1 hour is the same as $27 for 3 hours.
Answer:
the slope is 9
Step-by-step explanation:
The slope is how much it cost per hour so that means if you do 27 divided by 3 then you get 9 cause 3 hours is 27 but one hour is 9
how you check if your right is by adding 9 up 3 times
9+9+9=27
Hope this Helps!
