An inverse operation is when after you add, you subtract. Same with multiplication and division.
Answer:
Running rate of Destiny is 15 kmph
Step-by-step explanation:
Running rate of Destiny is the speed at which Destiny is running.
It can be calculated by finding the difference in the distance covered to the difference in the time taken.
So,
Running rate = Difference in distance covered / Difference in time taken
Difference in distance covered = 5-3 = 2 km
Difference in time taken = 10:44 am - 10:36 am = 44 -36 minutes = 8 mins =8/60 hour = 2/15 hour
Running rate = 2/(2/15) kmph =(2*15)/2 = 15 kmph
∴Running rate of Destiny is 15 kmph
Answer:
(i) The factors of the given polynomial is (x – 22) and (x + 10)
(ii) If she purchase 5kg papaya then she pays 110
Step-by-step explanation:
<h3><u>Given</u>;</h3>
- p(x) = x² – 12x – 220 per kg
<h3><u>To Find</u>;</h3>
- The factors of the given polynomial
- if she purchase 5kg papaya, what money she have to pay?
<h3>(i)</h3>
Now,
x² – 12x – 220 = 0
Splitting the middle term
x² – 22x + 10x – 220 = 0
x(x – 22) + 10(x – 22) = 0
(x – 22) + (x + 10) = 0
x – 22 = 0 or x + 10= 0
x = 22 or x = -10
Here, (-10) is the negative value hence it is not possible
So, The value of x is 22
The factors of the given polynomial is (x – 22) and (x + 10)
<h3>(ii)</h3>
if she purchase 5kg papaya then,
we know the price of 1 kg papaya i.e., 22 per kg
So,
5 × 22 = 110
Thus, if she purchase 5kg papaya then she pays 110

3v + 2 = 7v
2 = 4v
1/2 = v
QS = 3v + 2
= 3(1/2)+ 2
= 1.5 + 2
= 3.5
TV = 7v
= 7(1/2)
= 3.5
The sun of interior angles in a regular polygon can be represented as 180°(n - 2), where n is the sides of the polygon.
Hence, 180° * 9 = 1620°.
