(0.4)² = (0.4).(0.4) = 0.16
His error is, instead of raising (0.4) to exponent 2, he multiplied (0.4) by 2 , obviously which is wrong
Answer:
11°<x°<58°
Step-by-step explanation:
first find out how much x can be by using 180 degrees.
(5x+3)°+(5x+3)°+58=180°
(10x+6)°+58°=180°
10x°+64°=180°
10x°=116°
x=11.6°
hope that helps!
Answer:
Step-by-step explanation:
During the breaststroke competitions of a recent olympics, Nelson diebel swam 100 meters in 62 seconds, this means that his unit rate would be 100/62 = 1.61 meters per second.
Mike bower man swam 200 meters in 130 seconds. This means that his unit rate would be 200/130 = 1.54 meters per second. The rate of 1.61 meters per second is higher than the rate of 1.54 meters per second. Therefore, Nelson diebel swam at a faster rate.
Answer:
2nd option
Step-by-step explanation:
Using the sine ratio in the right triangle
sin32° = 
= 
= 
( multiply both sides by 6 )
6sin32° = BC
