Answer:
0.36363.....
repeating
Step-by-step explanation:
given :
total songs downloaded = 44
total favorite band songs = 16
number of favorite songs out of total songs downloaded
= total favorite band songs ÷ total songs downloaded
= 16 ÷ 44
= 0.3636363636363636363... (answer for part A)
by observation, we can see that the decimals 36 repeats over and over again and never stops. Hence we can say that the decimal is repeating (Answer for part B)
Step-by-step explanation:
1. 3.6 x 10^-1
2. 3.1 x 10^6
3. 5.3 x 10^-6
4. 4.2 x 10^-1
The discriminant of
ax^2+b+c=0 is
b^2-4ac
when the discriminant is
less than 0, then there are no real roots
equal to 0, then there is 1 real root
greater than 0, then there are 2 real roots
so
2x^2-5x+7=0
a=2
b=-5
c=7
discriminat=(-5)^2-4(2)(7)=25-28=-3
-3<0
no real roots
Answer:
m∠1 = 70°
Step-by-step explanation:
Step 1
Sum of angles on a straight line = 180°
Hence:
180° - 101°
= 79°
Sum of interior angles in a triangle = 180°
Therefore,
m∠1 = 180° - (79 ° + 31°)
m∠1 = 180° - 110°
m∠1 = 70°
