Population of a city is 36000 in 2005 by 2010 it has grown to 43800. If the city has grown linearly since 2005 and grows at the same rate what will the population be in 2015

Answers

The population of the city in the year 2015 will be 51,600.

What is the rate of change?

The rate of change is the speed at which variable changes over a specific period of time.

The population of the city in the year 2005 = 36,000

The population of the city in the year 2010 = 43,800

The change in population in 5 years is given by;

= Population in the year 2010 - Population in the year 2005

= 43,800 - 36,000

= 7800

The change in population in 5 years = 7800

Let us assume the number population in the year 2015 = x

Here, according to the question:

Since the change of rate is a linear growth since 2005.

The change in population every 5 years = 7800

The change in population in the next 5 years is;

Rate of change = Population in year 2015 - Population in the year 2010

7800 = x - 43,800

x = 7800 + 43800

x = 51,600

Hence, the population of the city in the year 2015 will be 51,600.

#SPJ2

36000 : 2005 = 43800 : 2010
Every five years it increases by 7800, so by 2015 it will be
43800 + 7800
= 51600

Keiko is mixing 4 cups of concrete to make a stepping stone. She needs 1.5 cups of sand and 2.5 cups of cement mix. Which statement best describes how much of each ingredient Keiko needs to measure? A. Keiko should make it easy and just measure about 1 cup of sand and 3 cups of cement mix since she needs a total of 4 cups. B. Keiko should measure exactly 1.5 cups of sand and 2.5 cups of cement mix to be sure the concrete will set properly. C. Keiko should make it easy and just measure about 2 cups of each since she needs a total of 4 cups.

Answers

Hello,
answer is C

m=-40h+130
Indeed
A=(1/2,110)
B=(3,10)

y-10=(10-110/(3-1/2)(x-3)
==>y=-100/(5/2)*(x-3) +10
==>y=-40x+120+10
==>y=-40x+130
(or m=-40h+130 )

An action movie production team needs glass spheres to hold a green liquid that looks like an explosive. If all of the available 3,392.92 cubic inches of the liquid is to be poured into 30 glass spheres, what should the diameter of each sphere be? Assume that each sphere is filled to the top.

Answers

The volume of a sphere:
$V=(4)/(3) \pi r^3$
r - the radius

3392.92 cubic inches are poured into 30 spheres.
$3392.92=30 * (4)/(3) \pi r^3 \n \n3392.92=40\pi r^3 \ \ \ \ \ \ \ \ \ \ \ \ |/ 40 \n \n84.823=\pi r^3 \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ |/ \pi \n \nr^3=(84.823)/(\pi) \n \nr=\sqrt[3]{(84.823)/(\pi)} \n \nr \approx \sqrt[3]{27} \n \nr \approx 3$

The diameter is twice the radius.
The diameter of each sphere should be approximately 6 inches.

Answer:

6 inches
