Answer:
2.3lego
Step-by-step explanation:
We can walk through this problem using the cross multiplication method
First 3 1/2 lego is same as 3.5lego
Hence If
Johnny builds 3.5lego in 60min
He can build xlego in 40min
Crosss multiplying we have
Xlego *60= 3.5*40
Xlego= 140/60= 2.3lego
Answer:
i beilive (a) is c idk i could be wrong..
Step-by-step explanation:
The Pythagorean Theorum formula is a(squared) + b(squared)= c(squared). If you plug in the numbers, the equation is 39(squared) + 80(squared)= c(squared). That simplifies to 1521+6400=c(squared). Adding results in 7921=c(squared). Finally, when you take the square root of both sides, you are left with 89=c (aka the hypotenuse)
