Out of 40 students in class 8,20% were absent.How many students were present?​

Mathematics

Alenkasestr [34]3 years ago

Understanding:

The total number of students is 40. 8.20% of them were absent, which means the rest were present, or in other words, (100-8.20)% were present or 91.8%. We can find the actual number of present students by multiplying the percentage of present students by the total number of students.

Solution:

Present Percentage = 91.8% or \frac{91.8}{100}

Present Students = (\frac{91.8}{100})(40)=36.72, since we are dealing with people we have to round it, so the present students are actually 37.

A smaller square is within a larger square as shown below. A point is chosen at random in the larger square. What percent of the
Bas_tet [7]

Answer: 84.5%

Step-by-step explanation:

15.2 × 15.2 = 231.04 cm² (area of the entire large square)

5.98 × 5.98 = 35.76 cm² (area of the small square)

large square - small square = area of the blue region

231.04 - 35.76 = 195.28 cm² (area of the blue region)

\frac{area of the blue region}{large square} = percentage of time that the point will be in the blue region

\frac{195.28}{231.04} = 0.845 --> 84.5%

Factor The Trinomial<br><br> 6x^2 + 24x - 72<br><br> Show work/steps
Ymorist [56]

6x² + 24x - 72

Divide all the terms by the greatest common of factor of 6. Makes factoring easier. We will need to put this 6 on at the end so keep it in mind.

(6x² + 24x - 72) / 6 = x² + 4x - 12

Your simplified equation is x² + 4x - 12

Now to factor we must find out what two factors of - 12 can be added together to equal 4. The factors are 6 and -2:

x² - 2x + 6x - 12

Now we must group and factor.

(x² - 2x) + (6x - 12)

We can pull an x out of the first binomial because both terms have that in common:

x(x - 2) + (6x - 12)

We can pull a 6 out of the second binomial for the same reason:

x(x - 2) + 6(x - 2)

The terms inside the parentheses match each other, this means (x- 2) is one of the factors of the original trinomial. The other comes from the terms on the outside x and + 6. Put them together, (x + 6)

So your factors are (x - 2)(x + 6); this isn't it though. We need the 6 from the top, the one we divided out to make factoring easier. We will put it on the outside of whichever factor you list first so that your final answer reflects that to get back to the original trinomial, you would have to multiply the whole thing by 6.

Your final answer is:

6(x - 2)(x +6)
