Meals with a Purpose are selling to-go charcuterie boards. You can purchase a small board or a medium board. On Thursday, Meals with a Purpose sold 10 small charcuterie boards and 12 medium charcuterie boards for a total of $144. On Thursday, Meals with a Purpose sold 5 sold charcuterie boards and 9 medium charcuterie boards for a total of $93.
What is the cost of each small charcuterie boards and one medium charcuterie boards?
The cost of each small charcuterie boards is $6 and one medium charcuterie boards is $7.
How to illustrate the information?A mathematical statement known as an equation is made up of two expressions joined together by an equal sign. It is a formula that expresses the connection between two expressions on each side of a sign. Typically, it has a single variable and an equal sign.
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
5c = 30
Divide both sides by 5
c = 30 / 5
c = 6
Therefore, based on the information the cost of each small charcuterie boards is $6 and one medium charcuterie board is $7.

Two factory plants are making TV panels. Yesterday, Plant A produced 6000 fewer panels than Plant B did. Five percent of the panels from Plant A and 4% of the panels from Plant B were defective. How many panels did Plant B produce, if the two plants together produced 1410 defective panels?
Plant P produced 15333 numbers of panels when the two plants together produced 1410 defective panels using unitary method.
What is unitary method?It is a method for figuring out a single unit's value, then multiplying that value by itself to get the required value.
Given data
Plant produces defective panels = 1140
Plant A produce = 5%
Plant B produce = 4%

Number panels Plant B produce = x
Number panels Plant A produce = x - 6000
[tex]\frac{5}{100}[/tex](x) + [tex]\frac{4}{100}[/tex](x-6000) = 1140

Given that 32 √ 2 = 2ª, find the value of a.
The value of 'a' in the given expression is 11/2.
Elaborate about the square root.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.

Determine whether the given measures define 0,1,2 , or infinitely many triangles. Justify your answers. a=10, b=15, m
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.

two cars travel down the highway at the same speed. if the first car travels 10 kilometers per hour faster than its current speed and the second car travels 10 kilometers per hour slower than its current speed than the first car would travel in two hours the same distance the second car would travel in thee hours. what is the original speed of the cars?
Answer:
The original speed of the cars is 50 km/hStep-by-step explanation:
Let the original speed of the cars be x.
The first carWhen speed is x + 10 the distance in two hours is:
2(x + 10)The second carWhen speed = x - 10 the distance in three hours is:
3(x - 10)Since the distance is same in both cases, set them equal and solve for x:
2x + 20 = 3x - 303x - 2x = 20 + 30x = 50The 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.

Look at the Example. The area of Rhode Island is about 43.07 billion square feet. About how many times as many times as great is the area of Colorado than the area of Rhode Island? Show your work.
According to the given statement
The area of Colorado is 67.43 times greater than the area of Rhode Island
Define Area?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.

Somerville has a population of 38,400 people. The town has been seeing its population decline by 3% every year. If this trend continues, what will the population be in 3 years?
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

[tex]5(x + x + 4)[/tex]
"the product of 8 and the sum of the second and the fourth":
[tex]8((x + 2) + (x + 6))[/tex]
According to the problem, the first equation should be 22 greater than the second equation:
[tex]5(x + x + 4) = 8((x + 2) + (x + 6)) + 22[/tex]
Next, simplify and solve the equation:

x = -11
Now that the value of x, and find the four consecutive odd integers:
x = -11
On substituting x value in the following terms:
[tex]x + 2 = -11 + 2 \\= -9\\x + 4 = -11 + 4\\ = -7\\x + 6 = -11 + 6 \\= -5[/tex]

Solve each system.
-6 = 3x - 6y , 4x = 4 + 5y
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.
