Answer: 1.75 or 1 3/4

Step-by-step explanation:

Because first you need to get R by it’s self by dividing it by 1/2 then if you divided it by one side you have to divide it by the other side so you get r=1.75 or 1 3/4.

Write your answer in scientific notation (2.5•10^8)•(2•10^3)
ICE Princess25 [194]

Answer:

5\times10^{11}

Step-by-step explanation:

In order to get the answer to this question you will have to put the scientific notations into their number form then multiply, then change back into scientific notation form.

(2.5\times10^8)\times(2\times10^3)

Turn the notations into their number form:

2.5\times10^8

The exponent is positive so move the decimal point to the right:

2.5\times10^8=250000000

Do the same with the second notation:

2\times10^3

Since the exponent is positive move the decimal point to the right:

2\times10^3=2000

Now multiply:

250000000 \times 2000 = 500000000000

Now turn the number into scientific notation:

500000000000 = 5.0\times10^{11}

=5\times10^{11}

Hope this helps.
