Two dice are rolled, find the probability that the sum is less than 13

1 answer:

7 0

100% of the rolls would be less than 13. The highest number on one die is 6, so even if you roll 2 dice the sum of both dice will always be lower than 13.
It's a 1:1 probablility.

Sarah goes for a run around her neighborhood. She runs 2.5 miles in 20 minutes. Sarah’s average speed is ______ miles per minute

MrMuchimi

I think I would first convert it to hours to solve it and then back to minutes at the end. Super strange it’s been asked for in minutes.

So to convert 20 minutes into hours, you need to multiply by 3.

This means you need to do the same to the other side, cause if they’ve travelled 2.5 miles in 20 minutes, they’d travel 3 times that in an hour.

So this is 7.5m/ph

But then they want it in minutes, so I suppose 7.5/60?

So 0.125m/pm?

Which set of numbers can represent the side lengths in cm of a right triangle HURRY

nikdorinn [45]

Answer:

Step-by-step explanation:

When finding the lengths of a right triangle, use the Pythagorean Theorem. That's a²+b² = c². C is the hypotenuse, which is always the longest side. So, when you plug in the numbers to work it out, it would be 10²+24² = 26². 10² = 100. 24² = 576. 26² = 676. So, your final equation would be 100+576 = 676. 100 added to 576 is 676, which makes this equation true. Therefore, you know that 10, 24, and 26 are the correct lengths of the right triangle.

Problem 2: Raylin wants to buy a new bike for $85. She already has $22 saved and her mom will

ohaa [14]

<h2>○=> <u>Correct option</u> :</h2><h2> $\color{plum}\tt\bold{(d) \: 25}$ </h2><h3>○=> <u>Steps to derive correct option </u>:</h3>

Cost of a bike Raylin wants to buy = $85

Money Raylin already has = $22

Money she needs :

$= \tt85 - 22$

$= \tt\$63$

Thus, money Raylin still needs = $63

Money she gets from doing one chore = 2.50

Number of chores the needs to do :

$= \tt \frac{63}{2.50}$

$\color{plum} =\tt 25 \: chores$

Thus, Raylin needs to do 25 chores to be able to buy the bike.

Therefore, the correct option is <em>(d) 25</em>
