The height of the stack of shim stocks will be  6 1/4 inches.

A mixed number is a fraction that is made up of a whole number and a proper fraction. A proper fraction is a fraction in which the numerator is less than the denominator. An example of a mixed number is 1 3/5. A whole number is a number that is not made up of a decimal or a fraction.

In order to determine the height of the stack, multiply the width of each shim stock by the total number of pieces. Multiplication is the mathematical operation that is used to determine the product of two or more numbers. The sign used to represent multiplication is x.

Height of the stock = width of one stock x number of pieces

34 cartons were delivered by the Yellow Bell Farm to various stores in the Hudson Valley.

Let the farm deliver 408 eggs to various stores around the Hudson Valley.

According to the question, a carton contains a dozen eggs.

A dozen is a grouping of twelve objects. It is abbreviated as doz or dz.

1 dozen = 12 eggs

So one carton contains a dozen eggs, or 12 eggs and

12 eggs needs 1 cartoon.

408 eggs needed = 408÷12 = 34 cartons

So 34 cartons were delivered by the yellow farm.

The common difference of Uth term is 0

A series of numbers called an arithmetic progression or arithmetic sequence (AP) has a constant difference between the terms.

The nth term of the sequence () is given by: If the first term of an arithmetic progression is and the common difference between succeeding members

Formula

a_n=a_1+(n-1)d

a_n = the nth term in the sequence

a_1 = the first term in the sequence

d = the common difference between terms

we gives

a_n=a+(n-1)d

a_11=a+(n-1)d

a_11=a+(11-1)d

a_11=a+10d

a_11=3+10d

10d=-3

d=(-3)/10,  a=3

To find the Uth term of sequence

U_n=a+d(n-1)

U_11=a+d(11-1)

apply the value of a=3,d=(-3)/10

U_11=3+((-3)/10 (11-1) )

U_11=3+((-3)/10 (10) )

U_11=3+(-3)

U_11=0

Therefore, Uth term of arithmetic progression is 0.

Answer:

11.25

Step-by-step explanation:

x/3 = 3.75
x = 11.25

Work has been corrected:

If x - 3.75 = 2/3, then x/3 = 3.75 (3.75 is 1/3 of the total money, X.)

We can find the value of x by isolating the variable:

x/3(3) = 3.75(3)
x = 11.25

Thus the total money, x, is 11.25

Solve this problem by setting up ratios with the information you know.

You know:

With this information, you can assume that he used 1/3 of his money.

With this set up a ratio comparing the numerical amount he spent to the ratio of his total money that he spent:

[tex]\frac{1}{3} =\frac{3.75}{x}[/tex]

x= the total amount of money he started with.

Now cross multiply to come up with a final equation:

x = 3.75 × 3

Solve: x = 11.25

The original amount of money he started with was $11.25

Equation of line passing through the points (-15,35) and (15,-19) with slope (m) -54/30 is;

y = -54/30 x + 8

What is equation of line?

Equation of line with slope m is,

y = mx + b

Now, The equation of line is find as;

Slope = -19 - 35 / 15 - (-15) = - 54/30

And, The equation of line in the slope form is;

y = mx + b

For finding the value of b we use any one point and put in the equation of line.

Take point (-15, 35) = (x, y)

Put in the equation of line we get;

35 = -54/30 * (-15) + b

35 = 27 + b

b = 8

Hence, Equation of line passing through the points (-15,35) and (15,-19) with slope (m) -54/30 is;

⇒ y = -54/30 x + 8

By applying the law of sines, the value of angle C to the nearest tenth is equal to 20.2 degrees.

In Geometry, there are different types of triangle based on the length of their sides and angles, and these are;

In Trigonometry, the law of sines is also referred to as sine law or sine rule and it can be defined as an equation that relates the side lengths of a triangle to the sines of its angles.

Mathematically, the law of sines is given by this equation:

[tex]\frac{sinA}{a} =\frac{sinB}{b} =\frac{sinC}{c}[/tex]

Substituting the parameters into the formula, we have;

sin51/9 = sinC/4

Cross-multiplying, we have:

4sin51 = 9sinC

sinC = 4sin51/9

sinC = (4 × 0.7772)/9

sinC = 3.1088/9

sinC = 0.4

C = sin⁻¹(0.3454)

C = 20.2 degrees.

In conclusion, we can logically deduce that the value of angle C is equal to 20.2 degrees.

Given:

A= 49.3

B=7.6

Now let find the lower bounds and the upper bounds

Lower bounds is calculated as:

Lower bounds=a-b

Lower bounds=49.35-7.69

Lower bounds=41.66

Upper bounds is calculated as:

Upper bounds=a-b

The peak wavelength that Earth emits as a blackbody is approximately equal to 9.657 × 10⁻⁶ m.

The Wien's displacement law is a consequence of Planck's radiation law, that states the brightness of a radiative body is a function of wavelength at a given temperature. Wien's displacement law states that peak wavelength is inversely proportional to the temperature (T), in Kelvin. The Wien's displacement law is represented by the following formula:

λ' = b / T

Where:

If we know that b ≈ 2.897 × 10⁻³ m · K and T ≈ 300 K, then the peak wavelength of the Earth is:

λ' = (2.897 × 10⁻³ m · K) / (300 K)

The total width of the room including the platform is 6.40 and the fraction of raised platform area to the total area is 1/6.

In such a fraction, the value that appears above the horizontal line is referred to as the numerator.

The fraction is the division of the two numbers but the division is not wholly complete.

A) Given the area of room = 46 14/15 = 704/15

Area = Width × Length

W × 7 1/3 = 704/15

W × 22/3 = 704/15

W = 704/15 × 3/22

W = 6.4

B ) Given the area of the platform as 7 37/45 = 352/45

Area of total room = 704/15

Fraction of  raised platform area to the total area = (352/45) / (704/15)

⇒ (352/45) × 15/704

⇒ 352/2112 = 1/6
