Answer:

5/6

Step-by-step explanation:

There are 30 total eggs

There are 30 -5 =25 not broken

P( not broken) = not broken/total

= 25/30

= 5/6

Use the Pythagorean theorem to solve this problem. So, 81+x^2=1681. ( Pythagorean theorem: a^2+b^2=c^2). x^2=1600. x=40.

in 2.5 hours, Mr. Castelli drives a distance of 125 miles. He wants to know his average driving speed in the meters per minute.

Ulleksa [173]

Answer:

1,350 meters per min

Step-by-step explanation:

Given that Mr. Castelli covers 125 miles in 2.5 hours, the average speed = $\frac{distance}{time}$ .

In miles per hr, average speed = $\frac{125}{2.5} = 50 miles/hr$ .

Converting 50 miles/hr to km per hr:

If 1 miles = 1.62 km (unit conversion)

50 miles = 50*1.62 = 81 km/hr

Converting 81 km/hr to meters per hr:

1 km = 1,000 m (unit conversion)

81 km = 81*1,000 = 81,000 m/hr

Converting 81,000 m/hr to meters per minutes:

60 mins = 1 hr

Therefore, average speed = $\frac{81,000}{60} = 1,350 meters/min$

Average driving speed of Mr Castelli in meters per minute = 1,350 meters per minute.

The graph shows the distance a car traveled, y, in x hours:

meriva

Answer:

The correct answer is 30

Step-by-step explanation:

Given: The x-axis represents the time in hours and the y-axis represents the distance in miles.

The line passes through the points $(2,60)$ and $(4,120)$

To find: The rise-over-run value for the relationship in the graph.

$\begin{aligned}m &=\frac{R i s e}{R u n} \\&=\frac{y_{2}-y_{1}}{x_{2}-x_{1}} \\&=\frac{120-60}{4-2} \\&=\frac{60}{2} \\&=30\end{aligned}$

Thus, the rise-over-run value for the relationship represented in the graph is 30.

Explain why percents are rational numbers.

levacccp [35]

Yes since percents can be decimals and these decimals can be illustrated as fractions hence, vice-versa.

80%= 0.8 = 4/5

A rational number is any number or numerical value which can be possibly stated in a fraction form of numbers, it basically has a numerator and denominator. Furthermore, the values of the numerator and denominator is integers and doesn’t equal to 0. In this given case of 8 over 5 or 8/5 this fractional number can still be expressed in a standard numerical form with a decimal as 1.6 without repeating decimal values. Unlike irrational numbers which is not possible, take for instance 3.1416… and so on which cannot be “fractionized”.
