Answer:
C) 3*10^6
Step-by-step explanation:
Divide the two numbers:
(6*10^-2)/(2*10^-8)=6/2*(10^-2/10^-8)=3*10^(-2-(-8))=3*10^(-2+8)=3*10^6
So C is correct
-2 + 8 = 6
because if you have 2 negative circles ●● and 8 positive circles ○○○○○○○○ then once you take away the first two circles you get you answer. You do the opposite. :) ( hope that make sense... )
Answer:
48 sweets
Step-by-step explanation:
5:2:4
Sarah: 5
Natasha:2
Richard:4
To find out how many sweets Richard got, we need to use 60 as the lcm. Since, we have a definite constant of 60 we need to divide it by the presiding ratio.
60/5 = 12
That means for a ratio of 1, everyone in the group recieves 12.
Now, we plug it in for each of the members.
5x = Sarah
2x = Natasha
4x = Richard
Sarah = 60 sweets
Natasha = 24 sweets
Richard = 48 sweets
∠C = 180° - 45° - 65°
∠C = 70°
b/sin B = c/sin C
b/sin 65° = c/sin 70°
b = c/sin 70° × sin 65°
b = 20/0.9397 × 0.9063
b = 19.289
b = 19.3
To find the area of a parallelogram you must multiply the base by the height. Since you need the length of the base you must take 15.5/3.1 which will = 5!
