How do you (experimentally) find the surface area of a pear?​
Lana71 [14]

Answer:

That's like saying "How do you (hypothetically) write a letter?"

Step-by-step explanation:

But you would probably have to measure the length, height, and width of this experimental pear and go from there.

Then plug your length, width, and height into your surface area formula.

It is also important to know where in the pear you are measuring. The top of the pear will have different measurements than the middle.

Use the commutative property to create equivalent expressions. Which expressions are equivalent to 2.2t + 3.5 + 9.8? Check all t
aev [14]

The answer is:

3.5 + 2.2t + 9.8 (Option 1).

9.8 + 3.5 + 2.2t (Option 4).

2.2t + 9.8 + 3.5 (Option 5).

The explanation for this answer is shown below:

1. The commutative property of addtion establishes that if you change the order of the addends, the sum will not change.

2. Let's say that a and b are real numbers, Then they can added them to obtain a result c:

a+b=c

3. If you change the order, you will obtain the same result:

b+a=c

4. Therefore, the only options that show the applicaction of this property, are the options shown above.
