iogann1982 [59]

So 1/2 for the Coin and 2/6 or 1/3 for the Coin

So you need to add them

1/2 + 1/3

you'll multiple the Numerators and denominators

1x1= 1

2x3= 6

Answer: So you have 1/6 chance of flipping a Coin on heads and also rolling 5 or greater on a dice :)

The area of circle is 770cm^2then find its circumfrence

Gala2k [10]

Answer:

The circumference is 98.39 centimeters (rounded to 2 decimal places)

Step-by-step explanation:

The area of a circle has the formula $\pi r^2$

The circumference of a circle has the formula $2\pi r$

First, let's find r from area given:

$\pi r^ 2= 770\\r^2 = \frac{770}{\pi}\\r=\sqrt{\frac{770}{\pi}} \\r=15.66$

Now, we can use this value of r and plug in into the formula for circumference. Shown below:

$2\pi (15.66)\\=98.39$

The circumference is 98.39 centimeters (rounded to 2 decimal places)

Please help with the following problem asap!!

umka21 [38]

Answer:

$8^7$

Step-by-step explanation:

$\dfrac{8^{15}}{8^7 \cdot 8} =$

Remember that $8 = 8^1$ .

$= \dfrac{8^{15}}{8^7 \cdot 8^1}$

When you multiply powers with the same base, add the exponents. Do this in the denominator.

$= \dfrac{8^{15}}{8^{7+1}}$

$= \dfrac{8^{15}}{8^{8}}$

When you divide powers with the same base, subtract the exponents.

$= 8^{15-8}$

$= 8^7$
