Answer:
The least number of questions a student can answer correctly is 32
Step-by-step explanation:
Let
x -----> the number of questions answered correctly
y ----> the total number of questions on a test

we know that
For a student to earn and A or B on a test, the ratio must be greater than or equal to 0.8
so

For y=40 questions
Find the value of x
substitute

solve for x
Multiply both sides by 40


so
The least number of questions a student can answer correctly is 32
<u><em>Verify the ratio</em></u>
For x=32, y=40

Compare
----> is ok
(5y-10)(2y-6)
10y-30y-20y+60
-40y+60
Hope that helps!
The value of a is 17 and the value of b is 6. The correct option is third option a = 17, b = 6
<h3>Calculating the length of the sides of a kite </h3>
From the question, we are to determine the values of a and b
From the given kite diagram, we can conclude that
/FG/ = /HG/
Thus,
30 = 2a - 4
∴ 2a - 4 = 30
2a = 30 + 4
2a = 34
a = 34 / 2
a = 17
Also,
/FJ/ = /HJ/
3b + 6 = 24
3b = 24 - 6
3b = 18
b = 18/3
b = 6
Hence, the value of a is 17 and the value of b is 6. The correct option is third option a = 17, b = 6
