Question

for what value of a will 8x10^3 be 40 times larger than a x10^2

Answer 1

for what value of a will 8x10^3 be 40 times larger than a x10^2

Answer 2

one second is approximately 0.000115741 of a day what is this number is scientific notation?

Answer 3

To find the value of a, we can set up the equation:

8x10^3 = 40(a x10^2)

Let's simplify this equation by multiplying 40 by a, which gives us:

8x10^3 = 40ax10^2

Now, let's simplify the powers of 10:

8x10^3 = 40ax10^2

8x10^3 = 40ax10^2

8000 = 400ax10^2

Now, let's divide both sides of the equation by 400x10^2:

8000 / (400x10^2) = ax10^2 / (400x10^2)

20 = a / 400

Multiply both sides of the equation by 400:

20 x 400 = a

8000 = a

Therefore, the value of a is 8000.

Answer 4

To find the value of a, we can set up the equation:

8x10^3 = 40(a x10^2)

Let's simplify this equation by dividing both sides by 40:

(8x10^3) / 40 = (40ax10^2) / 40

200 = a x10^2

Divide both sides by 10^2:

200 / (10^2) = (a x 10^2) / (10^2)

200 / 100 = a

2 = a

Therefore, the value of a is 2.

Answer 5

To express 0.000115741 in scientific notation, we would write it as 1.15741 x 10^(-4).
