0.05= 5*10^(-2)
As a matter of fact, the coefficient should be ≥ 1 and < 10.
0.05 written in scientific notation is 5*10^(-2)~
Hope this helps~
Answer:
36°, 36° and 108°
Step-by-step explanation:
let the equal angles be x then the third angle = 3x
The sum of the 3 angles in a triangle = 180°, thus
x + x + 3x = 180, that is
5x = 180 ( divide both sides by 5 )
x = 36
and 3x = 3 × 36 = 108
The 3 angles are 36°, 36° and 108°
first the square root of 4 is 2 so we can sub that in.
now we have 2(2*2)^-2.
2 * 2 of course is 4
with 2(4)^-2, keep in mind that negative exponents just mean to "flip" the number and turn the exponents positive.
so 4^-2 is the same as 1/4^2 or 1/16.
finally 1/16 * 2 = 2/16. 2/16 simplified is 1/8.
Number 1 is 15 number 2 is 9x3=27 and number 3 is 15 and number 4 is 5x7=35 number number 6 is 5 number 7 is 11 and that is about all i know hope this helps
