Whats the question that you need help with?
Answer:
Step-by-step explanation:
Population= 280000 people
Population growth rate= 8.5%
Population growth in a year=
{(100+8.5)÷100} × 280000 =303800 people
Pop growth in 8 years =
303800×8=
2,430,400 people
Answer:
The copy machine makes 32 copies per minute.
Step-by-step explanation:
Given that a copy machine makes 136 copies in 4 minutes and 15 seconds, to determine how many copies does it make per minute, the following calculation must be performed:
15 seconds = 0.25 minutes
136 / 4.25 = X
32 = X
Therefore, the copy machine makes 32 copies per minute.
Assuming second equation is 6x+8y=44
so first divide 2nd eqation by 2 to make it eqaier
3x+4y=22
sub 6x+4 for y
3x+4(6x+4)=22
3x+24x+16=22
minus 16 both sides
27x=6
divide both sides by 27
x=2/9
sub back
y=6x+4
y=6(2/9)+4
y=12/9+4 (4=36/4)
y=48/9
So... 1 foot = 30 cm
1 pound = 2 pounds
1 cup = 250 millilitres
I hope that helps!
