Can you form a right triangle form 21, 220, 221

1 answer:

4 0

From Pythagorean we know x^2 + y^2 = z^2. (x and y are smaller than z).

Let’s try!

21^2 + 220^2 = 441 + 48400 = 48841.

221^2 = 48841. The same!

So the answer is yes, you can make a right angled triangle.

You and your friend play a game. You answer 80% of the questions correctly and your friend answers 0.60 of the questions correct

bezimeni [28]

Answer:

Step-by-step explanation:

Assuming both players can answer the same question, the minimum number of questions is the smallest number that when multiplied by either 0.60 or 0.80 yields a whole number.

Let x be the number of questions, solving by trial and error:

$if\ x=2\\x*0.8=1.6\\x*0.6=1.2\\\\if\ x=3\\x*0.8=2.4\\x*0.6=1.8\\\\if\ x=4\\x*0.8=3.2\\x*0.6=2.4\\\\if\ x=5\\x*0.8=4\\x*0.6=3\\\\$

Therefore, the minimum number of questions in the game is 5.

while swimming a 2km race, Adam changes from breaststroke to butterfly every 200m. How many times does he switch strokes during

aleksley [76]

in the first half he would have swam 1 km. there are 1000m in a km so 1000/200=5 so he swam the first 200 fly, then a 200 breast, then a 200 fly again, then another 200 breast the finish the first 1 km with a 200 fly. so we switched strokes 4 times.

PS i wouldn't recommend doing a 2 km swim fly and breast
