If the population of a town grew 21% up to 15,049. What is the population last year?

1 answer:

5 0

You can try formulating an equation to model this change:

Let 'x' be the population of the town last year. It follows that:
$1.21x = 15049 
$
and hence
$x = \frac{15049}{1.21}$

Answer:

Step-by-step explanation:

Use the Pythagorean Theorem.

base² + height² = hypotenuse²

6² + 8² = hypotenuse²

100 = hypotenuse²

hypotenuse = √100 = 10 meters

A fish swims at a speed of 12 miles per hour. A boy swims at a speed of 4.4 feet per second. 3 ft = 1 yd 5280 ft = 1 mi How much

just olya [345]

You'll need to convert both speeds into yards per minute.

12 mph = 12 mph 1760 yd 60 min
---------- * ------------ * ----------
1 mile 1 hr

Note that "miles" cancels. So does "hours." Finish this work.

Then convert 4.4 ft/sec into yards per minute.

Then, finally, compare your two rates via subtraction of the smaller from the larger.
