1 answer:

Answer: Choice A) Solar energy; renewable

The image shows panels that convert <u> </u><u>solar energy </u> to electricity. This is an example of using <u>  renewable  </u> sources.

This is in contrast to something like coal energy which is nonrenewable. Coal is finite and will run out some day, unlike the sun's energy which won't run out any time soon. Sure it will eventually die off in about 5 billion years or so, but that timescale is much longer compared to the amount of coal is left. So this is a benefit to using renewable resources.

How many triangles can be made from the following three lengths: 3.1 centimeters, 9.8 centimeters, and 5.2 centimeters?
GenaCL600 [577]

Answer:

none

Step-by-step explanation:

We have three sides

Adding the two smallest sides together must be bigger than the third side

3.1+5.2 > 9.8

8.3> 9.8

This is false, so we cannot make a triangle

Find the circumference and area
kozerog [31]
C=2pi(r)

Pi=3.14

r=5.5

So C=2(3.14)(5.5)=34.56

So the circumference is 34.56 mi

And the area is A=pi(r)²

So you have

A=3.14(5.5)²

So A=95.03 mi²


So the area is 95.03 mi² and the circumference is 34.56 mi


Hope this helps!

Which of the following represents an example to calculate the sum of the numbers (accumulator)?A. number += numberB. total += nu
Hatshy [7]

Answer: The correct option would be,

B. total += number

Step-by-step explanation:

Since, the variable used to keep the running total is called sum of the numbers or accumulator,

Thus, accumulator = total + number,

i.e. we obtain accumulator by assigning total to total plus number.

Or, accumulator is,

total += number,

Hence, OPTION 'B' is correct.
