Of 20 students, 9 are girls

% of girls

% of boys

Answers

Answer 1
Girls: 45%
Boys : 55%
Answer 2

Answer:

45% and 55%

Step-by-step explanation:

Total student = 20

No of Girls = 9

No of boys = Total student - No of Girls

                  =20-9

                  =11

Percentage of Girls = (No of Girls / Total student) * 100

                           = (9/20)*100

                           = 45 %

Percentage of Boys = (No of Boys/ Total student) * 100

                           = (11/20)*100

                           = 55 %

In the survey 136 out of 160 depends on modular learning what percent of the reponents prefer modular learning?
A. 15%
B. 24%
C. 85%
D. 296%​

Answers

C. 85%

Set up the proportions
136/160 = ?/100
Then cross multiply.

100 x 136 = 13600
13600/160 = 85

Also you could use process of elimination. 296% wouldn’t work because that’s saying 136 is almost 3 times as many as 160. The other answers wouldn’t work because it’s clear that 136 is more than half of 160.

2. Which of the following is the difference of two squares?

Answers

Every difference of squares problem can be factored as follows: a2 – b2 = (a + b)(a – b) or (a – b)(a + b). So, all you need to do to factor these types of problems is to determine what numbers squares will produce the desired results.

Answer:

2 - [tex]b = 9\frac{1}{4}[/tex]

Step-by-step explanation:

Convert the mixed numbers into improper fractions.

2 • 2 + 1 = 5

4 • 11 + 3 = 47

[tex]\frac{5}{2} + b = \frac{47}{4}[/tex]

[tex]-\frac{5}{2} +\frac{5}{2} + b = \frac{47}{4} - \frac{5}{2}[/tex]

[tex]b = \frac{37}{4}[/tex]

[tex]b = 9\frac{1}{4}[/tex]

He needs 18,000 points.

He starts with 100, so subtract the 100 from 18,000 to get how many more points he needs:

18000 - 100 = 17,900 more points.

Divide the points needed by points per word:

17,900 / 50 = 358

He needs at least 358 words.

The inequality would be 50x+100>=18000, where x is the number of words.

Because 358 can be part of the solution, a solid dot on 358 and the line/arrow needs to point to the right for greater than.
