50*x=80 (x=percent in decimal form)
x=1.6 (divide both sides by 50)
Doubke check:
50*1.6=80
80=80
Convert 1.6 into a percent:
1.6 -> 160%

+

x =x +


+2x=x+

subtract x from each side

+ x=

now subtract

from each side
x= -0.1
Hope I could help
Suppose that every student in a discrete mathematics class of 25 students is a sophomore, a junior, or a senior: FALSE
<h3>
What is a sophomore?</h3>
- A sophomore in the United States is a student in their second year at an educational institution, usually a secondary school or a college or university, but also other types of post-secondary educational institutions.
- A sophomore in high school is equivalent to a tenth-grade or Class-10 student.
- In sports, a sophomore is a professional athlete in their second season.
As in the description, it is given that a sophomore in high school is equivalent to a tenth-grade or Class-10 student.
So, the above-given statement becomes false as it says that every student is a sophomore but the class has juniors and seniors.
Therefore, the statement "suppose that every student in a discrete mathematics class of 25 students is a sophomore, a junior, or a senior" is FALSE.

The complete question is given below:
Suppose that every student in a discrete mathematics class of 25 students is a sophomore, a junior, or a senior. Is the following statement true or false:
"The course must have at least five sophomores, or at least 20 juniors, or at least 10 seniors."
Answer:
1.50 x 10^11.
Step-by-step explanation:
There 11 digits after the 1 so it is:
1.50 x 10^11.
(1495 to 3 s. f. is 150)
<span>The <u>correct answer</u> is:
6/100.
Explanation<span>:
We look at place value to answer this. The digit in front of the decimal is the ones; directly after the decimal we have the tenths; behind this we have the hundredths; and behind this we have the thousandths.
6 is two places behind the decimal; this is the hundredths place. This means it is six hundredths, or 6/100.</span></span>
