Answer:
He could have asked the girls as well, and could have asked the entire class instead of just 10 students.
Step-by-step explanation:
By only asking 10 boys, he is not getting a complete representation of the whole class, as their are 30 students in the class.
Two factors of 64 that add up to 12 are 8 and 4.
8 x 8 is 64 so its a factor of 64
16 x 4 is 64 so its a factor of 64
8 + 4 = 12
Answer:
-7
Step-by-step explanation:
Answer:
0.5x+20=0.25x+30, m=40
Step-by-step explanation:
Blue: y=0.5x+20
Red: y=0.25+30
We’re looking for where the y (cost) is equal, so we can set the two equations to each other:
Isolate x:
0.5x+20=0.25x+30
0.5x+20-20=0.25x+30-20
0.5x=0.25x+10
0.5x-0.25x=0.25x+10-0.25x
0.25x=10
x=40
m= 40
the answer is 671,000,000
6.71 x 10^8 converted to standard form is equal to 671,000,000.
Hope it helps:)
