You will encounter 11 4s.
If you got 55.6% on a test and that test is worth 80%
So first let us calculate the actual percentage that you scored.
The actual percentage is

So your actual score on the test is 69.5%
The grading system varies across countries and states
The traditional grading scale is given below
90% to 100% corresponds to A grade.
80% to 89% corresponds to B grade.
70% to 79% corresponds to C grade.
60% to 69% corresponds to D grade.
0% to 59% corresponds to F grade.
69.5% can be rounded off to 70%
Therefore, 69.5% corresponds to C grade.
(note: the above grade is not valid in case your school follows a different grading scale)
Answer: $50
Step-by-step explanation:
30 × 10 = 40 ft² [garden area]
40 ÷ 25 = 1.6
1.6 ≈ 2
For the area of the entire garden, you need to buy two bottles of fertilizer.
25 × 2 = 50 [fertilization cost for the whole garden]
Answer:
89 2 irrational roots
Step-by-step explanation:
The discriminant Is b²-4ac when the equation is in the form
ax²+bx+c so in the equation
a=2 b=5 and c=-8
plug into the equation for the discriminant
so 5²-4(2)(-8)
25-(-64) 2 negatives make a positive so
25+64=89
since 89 isn’t a perfect square 2 irrational roots
