Answer:
64 for number 1. Not sure on number 2 sorry.
Step-by-step explanation:
Answer is 67.5
To get this you must first turn 54% into a decimal.
54%---> .54
125*.54= 67.5
So 54% of 125 is 67.5 <span />
<h2>10=)21 I know it is right </h2>
Answer:
∅1=15°,∅2=75°,∅3=105°,∅4=165°,∅5=195°,∅6=255°,∅7=285°,
∅8=345°
Step-by-step explanation:
Data
r = 8 sin(2θ), r = 4 and r=4
iqualiting; 8.sin(2∅)=4; sin(2∅)=1/2, 2∅=asin(1/2), 2∅=30°, ∅=15°
according the graph 2, the cut points are:
I quadrant:
0+15° = 15°
90°-15°=75°
II quadrant:
90°+15°=105°
180°-15°=165°
III quadrant:
180°+15°=195°
270°-15°=255°
IV quadrant:
270°+15°=285°
360°-15°=345°

2 bags
7 apples
A) Instead of a lets say:
a = 1, 2 , 3
If a =1 then, (you already know there are 2 bags) you have 1 apple in each bag, making total of 2 apples
If a =2 then you are having 2 apples in each bag making total of 4 apples
If a =3, 3 apples in each bag, making total of 6 apples
Conclusion:
2 * 1 = 2
2 * 2 = 4
2 * 3 = 6
See the difference & pattern here
Now lets do with a
2 * a = 2a
B) If a = 6
then, 2*6 = 12
lets continue from a =3
2*4=8
2*5=10
2*6=12
See the pattern again
Tip: Drawing making problem understand better.
