Answer:
Step-by-step explanation:
percent increase = increase divided by original number x 100
increase is the difference between the two numbers...
new number - original number.....4000 - 2800 = 1200
percent increase = (1200 / 2800) x 100
= 0.42857 (round to .4286) x 100
= 42.86 %.....if you need it rounded to the nearest percent, it would be 43% increase
(30x7)+(7x5) you basically just have break it up.I hope this really helped you.
For this case we have that by definition, the circumference of a circle is given by:

Where:
d: It is the diameter of the circle
They tell us that:

Substituting:

Thus, the circumference of the circle is 55 centimeters.
Answer:
Option B
Answer:
-3/4 pi radians
Step-by-step explanation:
<em>180° is 1 pi radian</em>
Hence, -<em>135° = -135/180 pi radians</em>
= -0.75 pi radians
= -3/4 pi radians
Step-by-step explanation:
40 = 2 * 2 * 2 * 5
28 = 2* 2 * 7
So now
The GCF = 2 * 2 = 4
