56:80 in lowest terms is 7:10
The √125 can be factored out to 25 and 5 then 25 can be factored out to 5 and 5. Then you pair up the numbers, you have a pair of 5's and a 5 left over. So the pair of 5's goes inside the radical as √5 and on the outside of the radical you have 5×3. So 3√125≈15√5.
Answer: -3 again
Step-by-step explanation: Sorry if it is wrong
Answer:
54
Step-by-step explanation:
total no. of marbles=100
no. of marbles Marcy had
=25% of 100
=25/100×100
=25
no. of marbles Roger had=21
Let the no. of marbles Ann had=x.
So, 25+21+x=100
46+x=100
x=100-46=54
Therefore, Ann had 54 marbles at the end of the game.
Step-by-step explanation:
distance formula d=
√(X2 - X1)² + (Y2 - Y1)²
= √(-9-15)² + (8-3)²
=√(-24)² + (5)²
=√576 + 25
=√601
