Answer:
The no. of variations in sign is 3
Step-by-step explanation:
Variation in sign occurs when every single time a negative product is produced by a pair of consecutive terms.
Therefore, the determination of the number of changes in sign in the given sequence is must.
Therefore, we take the product of the pair of consecutive terms as:
= - 3, variation in sign
= - 6, variation in sign
= 10, no sign variation
= - 20, variation in sign
= 24, no sign variation
The answer is £140
First you find 20% of 1200 (which is basically 20 times 12) which gives you £240.
You add £240 to £1200 which is £1440
Then you take £300 off £1440 since he already paid the deposit.
That leaves you with £1140
1140 divided by 10 is 114
Anything that has 1 has x + is A positive number for any purpose of the equation
SP = 24
PQ/PT = PR/PS
7/14 = 12/x
1/2 = 12/x
x = 24
