Elise did the problem wrong. She needed to find out the kids surveyed total. Her answer was a smaller number than the number of kids that liked math the most.

i’m not so good at explaining things :/
hope this helps a little!!

Error Analysis:

The mistake Elise of multiplying the revealed part (over whole) by the percentage given. She calculated 25% of the math students surveyed rather than finding the students in whole.

Correct Work:

20 students / .25 = 80 students surveyed

Or

20 students * 4 = 80 students surveyed.

Find the length of side y

Serggg [28]

Answer:

$\large\boxed{y=76.3359\ cm\approx76.3\ cm}$

Step-by-step explanation:

Use cosine:

$cosine=\dfrac{adjacent}{hypotenuse}$

We have

$adjacent=73\ cm\\hypotenuse=y$

and the angle 17°.

$\cos17^o\approx0.9563$

Substitute:

$\dfrac{73}{y}=0.9563$ <em>convert the decimal to the fraction</em>

$\dfrac{73}{y}=\dfrac{9563}{10000}$ <em>cross multiply</em>

$9563y=730000$ <em>divide both sides by 9563</em>

$y=\dfrac{730000}{9563}$

$y\approx76.3359$
