Answer: 288.17

Step-by-step explanation:

y ∝ x

⇒ y = kx

substituting the given value of x and y , the equation becomes

12 = 14 k

therefore

k = 12/14

k = 6/7

The formula then becomes

y = 6/7 x

when y = 247, we have

247 = 6/7 x

6x = 247 x 7

6x = 1729

x = 1729/6

x = 288. 17

Find the area of a circle with a circumference of \blueD{12.56}12.56start color #11accd, 12, point, 56, end color #11accd units.

mote1985 [20]

Answer:

12.55

Step-by-step explanation:

A = C²/4pi (3.14....) = 12.56² ÷ 4 × pi (3.14...) ≈ 12.556363, in this case we only take 12.55

Options for first blank: V=PR V=(PR)^(1/2) V=P^2R Options for second blank 16 5 4

Answer:

The formula to find the voltage is:

$v=\sqrt{P*R}$

And the voltage is 4 volts

Step-by-step explanation:

To get the equation of voltage you need to isolate v in one side of the equation. In order to do that, you need to remove the divisor/denominator and its square. How will you do that?

First, multiply both sides with R:

$P*R=\frac{v^{2} }{R} *R$

That would result into removing the divisor R from the right side of the equation:

$P*R=v^{2}$

Next, square-root both sides:

$\sqrt{P*R} =\sqrt{v^{2} }$

That would result in removing the square of v from the right side of the equation:

$\sqrt{P*R} =v$

Thus we get the equation, $v=\sqrt{P*R}$ .

To find out the voltage, simply replace R with 32 and P with 0.5

$v=\sqrt{0.5*32}$

$r=\sqrt{16}$

$r=4$

Thus, the voltage is 4 volts.

Explain how to estimate 586 - 321 two different ways

murzikaleks [220]

<span>To estimate 586 - 321, you can round the numbers up or down to the nearest five.
586 can either become 570, rounding up, or 585, rounding down, which is closer. 321 becomes 320. It's not close enough to 325, nor to 315, for either of those to be good choices. 570 - 320 = 250 and 585 - 320 = 265. The actual solution to the original problem is 265, so, the second estimate, because they both go down by 1, is the closest.</span>
