Area = (1/2)bh   
h = b-4

(1/2)b(b-4) = 48
b(b-4) = 48 : (1/2)
b² - 4b = 96
b² - 4b - 96 = 0
D = (-4)² - 4·(-96) = 16 + 384 = 400 = 20²
b₁ = (4-20)/2 = -8     ∅
b₂ = (4+20)/2 = 12

The length of the base = 12 m

ipn [44]

Answer:

Y = 0

Step-by-step explanation:

If x = 5 then 2x + y = 10 is 10 + y = 10 (2*5 = 10) and so 10 + 0 = 10. Y = 0

Why isn’t the maximum ACT score (36) at the 100th percentile?
irga5000 [103]

Answer and Explanations

ACT score percentile help colleges compare students with one another, rather than just looking at everyone’s score. The  score range is between 1 and 36, the highest score that one can receive on the ACT is 36. Moreover, 36 is the perfect score.

The maximum ACT score (36) is that in 2018, only 3,741 students (out of millions of test-takers) scored a perfect 36 on the ACT.  The 99th percentile of test-takers includes those who earn 35 or 34 on the ACT. We can miss up to five questions on the ACT and still earn a 36. That is a reason why the maximum ACT score is 36 at the 100th percentile.

The ACT score report will provide more information about test-taking experience in the form of sub score. The higher the score,  you will get into the colleges of your choice.
