In mathematical operations with significant figures the answer must r<span>eflects the reliability of the least precise number. 225 has three significant figures, whereas 0.015 has two -leading zeroes are not significant figures, so our answer must have two significant figures to reflect the reliability of the number 0.015, which has two significant figures.

We can conclude that <span> the number representing the amount of calcium in the liquid will have

Since it doesn't give us a specific variable to use I'll just use y. and my phone doesn't have the less than or equal to sign so ill just say how to draw it i guess.
41. y (less than sign with line) 4.
42. y × (-7) > 42
43. y ÷3 - 5 (greater than sign with line) 11
and im not 100% sure on 44 so... anyway you probably know what the greater than or equal to sign and the less than or equal to sign are so. yeah hope it helped.

Answer: Rounded: 236 seconds
Not rounded: 236.07 seconds
Step-by-step explanation: We know that it takes the car 54.9 seconds to travel one mile, and we know that 1 times 4.3 is 4.3, so 4.3 times 54.9 equals 236.07 seconds.
