Answer:

Number 3 is correct.

Now, we're trying to find the opposite side of the triangle.

Using the laws,

What is the area of the trapezoid ?
Helga [31]

Answer:

<h2>432 ft²</h2>

Step-by-step explanation:

The formula of an area of a trapezoid is:

A=\dfrac{b_1+b_2}{2}\cdot h

<em>b₁, b₂</em><em> - bases</em>

<em>h</em><em> - height</em>

<em />

We have:

<em>b₁ = 20 ft, b₂ = 16 ft, h = 24 ft</em>

Substitute:

A=\dfrac{20+16}{2}\cdot24=\dfrac{36}{2}\cdot24=18\cdot24=432\ ft^2

Derek scored a total of 34 points in the first four basketball games. If he continues to score at this rate, how many points wil
Rufina [12.5K]

Answer:

153 points

Step-by-step explanation:

Set up a proportion:

34/4 = x/18.

18/4 does not equal a whole number. So, reduce 34/4.

34/4 becomes (when divided by 2 on both the top and the bottom) 17/2.

18/2=9. 9*17=153.

Prof Liu gave the same quiz to the students in her morning class and in her afternoon class. the average score for the two class
yaroslaw [1]

Answer:

Step-by-step explanation:

Given that Prof  Liu gave the same quiz to the students in her morning class and in her afternoon class. the average score for the two classes combined was 84.

(1) The average score for the students in the morning class was 80

(2) the average score for the students in the afternoon class was 86

Let m be the no of students in I class and n in II class

Total of I class = 80m and

Total of II class = 86n

Total of both classes = 80m +86n

Average =\frac{80m+86n}{m+n} = 84

m cannot be equal to n because in that case average would have been 83

If m >n, then say n =m+a

then average = \frac{80m+86m+86a}{2m+a} =84

Because 86 is more times added, average score would decrease hence we would not get 84.

So I class is getting less score of 80 to get a score average of more than 83 (the average) the class II should have more students.
