you have to calculate the SID number and then take it upon yourself and divided X it's actual number and then there's a chance and the answer would be c.72
x/5 = 6/15
15x = 30
x = 2
answer
x = 2 ft
y/10 = 6/15
15y = 60
y = 4
answer
y = 4 ft
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
0.0167
Since the decimal is present, start from the left side of the number and move to the right until you hit the first Non-Zero number. That number will be the first significant figure, and the number you will start counting from. That’s the first, the second is next, and lastly the third. You round the LAST significant figure, in this case a 6 followed by a 6, meaning you round UP.
