A cable 90.6 meters long is cut into two pieces so that one piece is 37.2 meters longer than the other. Find the length of each piece of cable.

Answers

Answer 1

Answer:

Answer:

53.4

Step-by-step explanation:

It said cut that means subtraction also in different length. So you subtract 90.6-37.2=53.4

Answer 2

Answer:

Answer:

26.7 meters and 63.9 meters

Step-by-step explanation:

37.2 + 2x = 90.6

-37.2 -37.2

2x = 53.4

53.4 ÷ 2 = 26.7 meters

26.7 + 37.2 = 63.9 meters

63.9 + 26.7 = 90.6 meters

Hope that helps.

Answer:

(a) 0.00000221 (b) 4.2 x $10^(5)$

Step-by-step explanation:

(a) $10^(-6)$ means you need to move the decimal left (because of the negative) 6 spaces. So you have 2.21 move the decimal 6 spaces left and you end up with 0.00000221

(b) If you have 420,000 and you count 5 spaces from the last number, that leaves the decimal inbetween the 4 and 2 so your answer will be 4.2 x $10^(5)$
