Answer:

The highest score is the last one 17/20

Step-by-step explanation:

<u>Step 1:  Convert all to percentage </u>

21/25 -> 0.84 * 100 -> 84%

82%

0.8 * 100 -> 80%

17/20 -> 0.85 * 100 -> 85%

Answer:  The highest score is the last one 17/20

\huge\boxed{\frac{17}{20}}

We will convert each of the scores to a percentage.

\frac{21}{25}*\frac{4}{4}\to\frac{21*4}{25*4}\to\frac{84}{100}\to84\%

82\%

0.8*100\to80\%

\boxed{\frac{17}{20}}*\frac{5}{5}\to\frac{85}{100}\to\boxed{85\%}

So, the answer is the last option.

2. A group of activists wants to raise money for a good cause, so they decide to sponsor a bicycle race. It receives $60 per cyc
Scorpion4ik [409]

Answer

Step-by-step explanation:

  • The number of cyclists the group needs to raise at least $57,000 must be at least 1000 cyclists
  • Let x represent the number of cyclists.
  • Since, the activists receive $60 per cyclist entry and $15,000 in donations, hence:
  • Revenue = 60x + 15000
  • Also, the cost of the race is $18 per entry, hence:
  • Cost = 18x
  • They need to raise at least $57,000, hence:
  • Profit ≥ 57000
  • Revenue - Cost ≥ 57000
  • (60x + 15000) - 18x ≥ 57000
  • 42x ≥ 42000
  • x ≥ 1000
  • Therefore the number of cyclists the group needs to raise at least $57,000 must be at least 1000 cyclists

The graph of f(x)=ax^2 is narrower than the graph of g(x)=dx^2 when a&lt;d
Lynna [10]

Answer:

Step-by-step explanation:

as given in question that a > 0 so

if we put a=1

we get g(x) = f(x)

now put a =2

we get

g(x) = 2 f(x)

here we can see that g(x) would always be greater than or equals to f(x)

so we can say that the graph of g(x) will never be narrower than graph of g(x)
