The area of triangle DEF is 2137.5 cm²

Solution:

Given data:

Area of ABC = 38 cm²

Scale factor = 7.5

To find the area of DEF:

<em>Area of dilated image = Area of original image × (scale factor)²</em>

Area of DEF = 38 × (7.5)²

                    = 2137.5 cm²

Area of DEF = 2137.5 cm²

The area of triangle DEF is 2137.5 cm²

Categorize these samples as representative or not representative of the given populations.
yuradex [85]
<u>Representatives: This means that a certain amount of people would constitute what the majority would think too.

</u>1) Tina interviews the school's soccer team about the exercise habits of  the students at her school. (implying all the students). This means that Tina only goes to the soccer team instead of the whole school to find out the whole school's exercise habit.
<u></u>2) Alana also counts as representatives, because she did not interview ALL of the teachers, rather just a selected majority (in this case)
5) For Jeremy, he only interviews 5 students from each class rather than all students<u>
Not Representatives: Each person is given a choice of opinion and does not affect other people.
</u>3) Joe talks to fathers of high school students, which could be larger than just 'representatives', and implies a larger group of people, and is not as selective as having representatives
<u />4) Social Media constitutes of a large group of people, generally larger than a school, and if people take time to take the survey, it will generate a larger test-group. Also, everybody answering the survey would take time to think about themselves, and only represent themselves, and not others.

Put these fractions from smallest to greatest<br><br>6/5, 8/15, 1/4
valkas [14]
1/4, 8/15, 6/5
One way to figure this out is to divide the fractions and find which number is bigger
Or you should know 1/4= .25 , 8/15 is around half or .5 and 6/5  the numerator is larger than the denominator, so it would be bigger than 1 <span />

Helpppp :(((( 75 points and brainliest!!!! for good answers only
Mamont248 [21]

option B

Cos theta is positive and sin theta is negative in quadrant IV

Cos \ \theta =\dfrac{4}{5}=\dfrac{adjacent \ side}{hypotenuse}

We have to find opposite side using Pythagorean theorem.

x² + 4² = 5²

x² + 16 = 25

       x² = 25- 16

       x² = 9

       \sf x =\sqrt{9}\\\\x = 3

\sf \ sin \ \theta =\dfrac{opposite \ side}{hypotenuse}\\Sin \  \theta =\dfrac{-3}{5}
