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.

What's the degrees in this equation.

vfiekz [6]

My work shown is how to get x. now that you have x plug it into the equation.
To test your answer add both 51 and 39, and you should get 90 (the measurement of a right angle)
