What's the product of 21 and (6.3 times 10-4)

Mathematics

21(6.3 x 10 - 4).  Remember PEMDAS.  Everything done in parenthesis is done first.

Within the parenthesis, there is multiplication and subtraction.  In PEMDAS, multiplication/division comes before addition/subtraction, so 6.3 x 10 = 63.
63 - 4 = 59
21(59) = 1,239.

Find the value of x.
allsm [11]

Answer:

3 \sqrt{5}

Step-by-step explanation:

x is the center of the circle.

the chord of length 12 can be splitted into two parts of 6 length each.

since the radius does not change when it touches another end of the circle, we can safely calculate our radius to be the hypotenuse of the triangle formed by the length of the chord and 3.

Select the equivalent expression . ( 8^ -5 2^ -2 )^ -4 =?
Vikki [24]

Answer: C

Step-by-step explanation:

When there is division inside a set of parentheses, you can distribute the power to each term. When you take a power to another power, you multiply the powers.

-5 x -4 = 20

-2 x -4 = 8

So your answer is:

\frac{8^2^0}{2^8}

A density graph for all of the possible times from 50 seconds to 300 seconds
vazorg [7]

Answer: D. The probability of a time from 75 seconds to 250 seconds.

Step-by-step explanation:

We know that a density curve graph for all of the possible values  from a  to b can be used to find the the probability of the values from a to b .

Given: A density graph for all of the possible times from 50 seconds to 300 seconds.

Then it can be used to find the the probability of a time in the range from 50 seconds to 300 seconds.

From all the given option only option D gives the interval which is lies in the above range.

i.e A density graph for all of the possible times from 50 seconds to 300 seconds can be used to determine the probability of a time from 75 seconds to 250 seconds.
