Kelly's Cafe offers two kinds of espresso: single-shot and double-shot. Yesterday afternoon, the cafe sold 4 single-shot espressos and 6 double-shot espressos. What percentage of the espressos sold were single-shot?

Answers

Answer:

40% of espresso was single-shot.

Step-by-step explanation:

To make a percentage, you need to think of a fraction first. The denominator is always 100 in a percent. If my answer is 40%, the fraction would be 40/100. If there was 6 double shots and 4 single shots, those two together would make 10. 10 x 10 is 100. So really, you just have to multiply 4 by 10 to get the percentage.

Hope this helped, if your confused, just ask me :]

we can use the equation 45m < 481

we can replace m to see where it caps.

and the cap is 10.

we can replace m to check our work

45(10) < 481

The author believes that all young students should learn another language.Which sentence from the passage best supports this statement?The Benefits of Study Abroad The benefits of studying abroad are endless. Often, people think of studying abroad as something that is just for college students. Some teens have the opportunity to study abroad, but there are not as many programs for young people in public schools to study abroad as there should be. Younger kids who are trying to learn another language will improve their skills so much by actually spending time in a place where people speak the language the kids are studying. The younger someone is, the easier it is to learn another language, and in this global world, being able to speak more than one language is a valuable skill. Think of how much students who are studying French would get out of going to Paris. Students could live with a Parisian family, attend a French school, and eat French food. They could live French culture instead of just reading about it in a book. Some people may be quick to bring up the topic of moneywouldn't it cost a lot to send a child to study abroad? Not necessarily. There are exchange programs and scholarships available to pay for young adults to have this kind of experience. Parents who don't want their children gone for an entire school year can relax. Half-year and summer programs are also available. Many schools even offer one- or two-week opportunities, though parents will usually have to pay for those trips out of pocket. Students who attend immersion schoolsschools that teach classes only in the secondary languagecan take the final step in becoming fluent when they study abroad. For students who have not had the immersion school experience, study abroad can be a good substitute. Of course, if going abroad is simply not an option for a child, parents should at least have him or her attend an immersion school or take intensive language courses. Parents should not throw away the idea of study abroad for their child until they have looked into all of the optionsthey might be surprised with what they find.
