The population of Somerville is approximately 35047 after a depreciation of of 3% every year .

Depreciation is economics refers to two different aspects of the same idea: first, the actual decline in an asset's fair value as it is used and worn, such as the annual decline in value of factory equipment; and second, the allocation in accounting statements of the asset's original cost to the periods during which it is used.

Here depreciation is the gradual decline in population each year in the town.

The rate of depreciation or decline is the percentage amount of population that decreases every year.

The formula used to calculate depreciation is given by:

[tex]A=P(1-r)^t[/tex]

Given the rate of depreciation as 3%.

Population at present = 38400

Population after 3 years:

= 38400 (1 - 0.03 )³

= 38400 ( 0.97 )³

= 35046.6432

≈ 35047

Hence the population after 3 years will be approximately 35047.

Step-by-step explanation:

I should choose second or other campus, as it is cost effective.

We will begin with forming the equation according to the information provided in question. Let us represent the number of hours with t.

Cost on choosing first or one campus to play tennis-

Cost = 25 × t

Cost on choosing second or other campus to play tennis -

Cost = 10 + 20 × t

Now finding cost on each campus for duration of ten hours.

First campus -

Cost = 25 × 10

Cost = 250

Second campus -

Cost = 10 + 20 × t

Cost = 10 + 20 × 10

Cost = 10 + 200

Cost = 210

Therefore, to practice for a total of 10 hours, I should choose second or other campus, as it is cost effective.

After solving each system, -6 = 3x - 6y, 4x = 4 + 5y, the values of x and y are calculated to be 6 and 4 respectively.

The two equations,  -6 = 3x - 6y, and 4x = 4 + 5y can be considered as linear equations as the highest power of the variables in these equations is one.

By rearranging the first equation, the value of x can be found to be,

-6 = 3x - 6y

3x = 6y - 6

x = 6y - 6 / 3

Putting the calculated value of x in the second equation,

4x = 4 + 5y

4(6y - 6 / 3) = 4 + 5y

24y - 24 / 3 = 4 + 5y

24y - 24 = 3 ( 4 + 5y)

24y - 24 = 12 + 15y

Rearranging,

24y - 15y = 12 + 24

9y = 36

y = 36 / 9

y = 4

To solve for x, put y = 4 in the first equation as follows,

-6 = 3x - 6y

-6 = 3x - 6(4)

-6 = 3x - 24

Rearranging,

24 - 6 = 3x

18 = 3x

x = 18/3

x = 6

Thus the value of x and y in these systems are calculated to be 6 and 4 respectively.

According to the given statement

The area of Colorado is 67.43 times greater than the area of Rhode Island

Area is typically thought of as a specific instance of volume for two-dimensional regions. By applying axioms, one can define area as the relationship between a set of real numbers and a collection of particular plane figures.

Area is a mathematical concept that describes the size of a region on a planar or curved surface. The area of an open surface or the border of a three-dimensional object is referred to as the surface area, whereas the area of a plane region or plane area refers to the area of a form or planar lamina.

According to the given values;

The area of Rhode Island = 43.07 billion square feet.

The area of Colorado = 2.9045 trillion square feet.

43.07 billion =43,070,000,000

2.945 trillion =2,9045,000,000,00

Now we have to find how many times as great is the area of Colorado than the area of Rhode Island.

For this ,we divide area of Colorado by area of Rhode Island.

=2,9045,000,000,00/43,070,000,000

=67.43

So, the area of Colorado is 67.43 times greater than the area of Rhode Island.

Gm (5, 45) = 15

   The geometric mean is defined as a type of measure that is calculated as the root of a product between a set of numbers, it can be expressed as follows:

Gm (a,b) = √ab

  Then in our case that we have the values 40 and 15, these are equivalent to the variables a and b

  We substitute and solve for the square root

Gm (5, 45) = √5×45

Gm (5, 45) = √225  ;    In this case the square root is direct-

The value of 'a' in the given expression is 11/2.

The square root formula can be used to calculate the square root of any number. The square root of any number is the value that, when multiplied by itself, yields the original number. Each number has two square roots, one positive and the other negative. For example, the number four has two square roots, -2 and 2.

Given [tex]$32 \sqrt{2}=2^a$[/tex]

We can write 32 as:

32 = 2 × 2 × 2 × 2 × 2

32 = [tex]2^{5}[/tex]

Let the original speed of the cars be x.

When speed is x + 10 the distance in two hours is:

When speed = x - 10 the distance in three hours is:

Since the distance is same in both cases, set them equal and solve for x:

The original speed of the cars is 50 km/h

Answer:

Original speed = 50 km/h

Step-by-step explanation:

Given that,

→ first car travels 10 km faster than its current speed. It would travel in two hours the same distance.

→ second car travels 10 km per hour slower than its current speed. It would travel in 3 hours the same distance.

Then the equation will be,

→ 2(x + 10) => 1st car

→ 3(x - 10) => 2nd car

→ 2(x + 10) = 3(x - 10)

Now the original speed of the cars is,

→ 2(x + 10) = 3(x - 10)

→ 2x + 20 = 3x - 30

→ 2x - 3x = -30 - 20

→ -x = -50

→ [ x = 50 km/h ]

Hence, the original speed is 50 km/h.

We can construct an unlimited number of triangles when given only two sides and no indication of the angle, such as a = 10m and b = 15m

Consider this:

With 10m and 15m side lengths and an angle value ranging from 0 to 360 degrees, how many distinct triangles are possible?

Make one of the triangles with sides of 10 meters, 15 meters, a 30 degree angle, and a third side that may be adjusted to your preferred length using a protractor. A triangle has been built by you.

By changing the length and angle of the third side, we can produce a completely different triangle that is similar to this one.

Keep in mind that you choose the side lengths and angle. This suggests that you might make a different decision. Using the same angles, you can make an infinite number of different triangles.

As a result, using just one angle and one side length, we can create an unlimited number of triangles.

m ∠EFH = 59.5°

m ∠GFH = 59.5°

From the question, we are to determine measures of the indicated angles

The angles are ∠EFH and ∠GFH

From the given information,

FH bisects ∠EFG

Since FH bisects ∠EFG,

Then,

m ∠EFH  = m ∠GFH

and

m ∠EFH  + m ∠GFH = m ∠EFG

Then,

We can write that

m ∠EFH  + m ∠EFH = m ∠EFG

2 × m ∠EFH = m ∠EFG

2 × m ∠EFH = 119°

m ∠EFH = 119°/2

m ∠EFH = 59.5°

Let small charcuterie boards = c

Let medium charcuterie boards = m

Therefore, the equation will be:

10c + 12m = 144

5c + 9m = 93

Multiply equation i by 5

Multiply equation ii by 10

50c + 60m = 720

50c + 90m = 930

Subtract

30m = 210

m = 210/30

m = 7

Therefore, 5c + 9m = 93

5c + 9(7) = 93

5c + 63 =93

5c = 93 - 63
