Hi Friend,
Solution is as follows!
Pupils in ROSE SCHOOL = 2185
GIVEN THAT,
there are 307 people more in lily school
HENCE,
people in LILY school will be = 2180 + 307 =<span>2487.
</span>
ROUNDING OFF TO NEAREST 10 we get
<span>2490.
</span>____________________________________________________________
(ii)TOTAL NUMBER OF PUPIL IN BOTH ROSE AND LILY SCHOOL=
2185+2487=<u><em>4672</em></u>
ROUNDING OFF TO nearest 100 we get
<u>2500
</u>
HOPE THIS HELPS!!!
Answer:
Natalie is 13 years old, while Fred is 28 years old.
Step-by-step explanation:
Given that if you add Natalie’s age and Fred’s age, the result is 41, and if you add Fred’s age to 3 times Natalie’s age, the result is 67, to find how old Fred and Natalie are, the following calculation must be performed:
N + F = 41
3N + F = 67
(67 - 41) / 2 = N
26/2 = N
13 = N
13 x 3 + F = 67
39 + F = 67
F = 67 - 39
F = 28
28 + 13 = 41
Therefore, Natalie is 13 years old, while Fred is 28 years old.
( 6 − 7 i ) ( − 8 + 3 i )
First FOIL:
( 6 − 7 i ) ( − 8 + 3 i ) = -48 + 18i + 56i -21i^2
Combine like terms
= -48 + 74i -21i^2
Convert i^2 = -1
= -48 + 74i -21(-1)
And simplify
= -48 + 74i + 21
= -27 + 74i
The zeroes are also the x-intercept or the roots of the function
