Answer:

4.5 cm.

Step-by-step explanation:

We have been given that circle O has a circumference of approximately 28.3 cm.

We will use circumference formula to solve for the radius of our given circle.

$\text{Circumference of a circle}=2\pi r$

Upon substituting the measure of circumference in above formula we will get,

$28.3=2\pi r$

$r=\frac{28.3}{2\pi}$

$r=4.504084889500638\approx 4.5$

Therefore, the radius of circle O is 4.5 cm.

A skier is trying to decide whether or not to buy a season ski pass. A daily pass costs $77. A season ski pass costs $450. The

n200080 [17]

Answer:

Step-by-step explanation:

Given:

Daily pass = $77
Season ski pass = $450
Skis = 20

77 + 20 = 97

450 + 20 = 470

Keep multiplying 97 with random numbers until it passes 470.

97 × 4 = 388

97 × 5 = 485

So, the skier will have to pay daily passes 5 times to be more expensive than the season pass.

Hope this helped.

#10-1 : What is the probability of randomly choosing a diamond card from a regular deck of 52 cards? What is the probability of

Alchen [17]

$\huge{\boxed{\frac{1}{4}}}\ \ \huge{\boxed{\frac{1}{4}}}$

There are $13$ of each suit in a deck of $52$ cards.

This means the probability of drawing a diamond card is $\frac{13}{52}$ . You can divide the numerator and denominator each by $13$ to simplify. $\frac{13}{52} \div \frac{13}{13} = \boxed{\frac{1}{4}}$

Since there are the same number of clubs as there are diamonds, the probabilities are the same.
