A town has a population of 4000 and grows at 3.5% every year. To the nearest year, how long will it be until the population will reach 7500?

The correct answer is 25 years.

Step-by-step explanation: If the population increases by 3.5 %, and the population to start off with is 4,000, this means the population will increase by 140 people every year. (4,000 x 0.035= 140) 140 x 25= 3,500 thus 4,000+ 3500= 7500... 25 years

y=mx+b

step-by-step explanation:

m is slope, b is y-intercept

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.
