The surface area of the rectangle prism is 52.05 in²

The total surface area of a prism is the sum of the areas of its lateral faces and its two bases.

The formula for the surface area of a prism is obtained by taking the sum of (twice the base area) and (the lateral surface area of the prism). The surface area of a prism is given as S = (2 × Base Area) + (Base perimeter × height) where "S" is the surface area of the prism.

l = 7.2 in

b = 1 1/2 = 3/2

h = 1 3/4 = 7/4

SA = 2( 7.2×1.5+ 7.2 × 1.75 + 1.75×1.5)

SA = 2( 10.8 + 12.6 + 2.625)

SA = 2 ( 26.025)

SA = 52.05 in²

therefore the surface area of the rectangle prism is 52.05 in²

Answer:

I have graphed it and attached it to the explanation.

Step-by-step explanation:

The required cost of the meal given as a hot dog is of $6 and the hamburger is of $8.

Simultaneous linear equations are two- or three-variable linear equations that can be solved together to arrive at a common solution.

Let's call the cost of a hot dog meal "x" and the cost of a hamburger meal "y".

From Mrs. Hammond's purchase, we know that:

x + 3y = 30   -- - - - - -(1)

From Mr. Weber's purchase, we know that:

3x + 3y = 42 - - - - - -(2)

We can use substitution to solve for one of the variables in terms of the other. If we substitute the first equation into the second equation:

3x + 3y = 42

3x + 3(30 - x)/3 = 42

3x + 30 - x = 42

2x = 12
x = 6

now,
6 + 3y = 30
3y = 24
y = 8

Thus, the required cost of the meal given as a hot dog is of $6 and a hamburger is $8.

Working alone, Allen can build 1/8 of the fence in 1 hour and working together, Allen and Danny can build 1/X of the fence in 1 hour, where X is their combined rate.

Let's say the total time required to build the fence is T hours.

After 2 hours, Allen has completed 1/8 * 2 = 1/4 of the fence.

So, the remaining work to be done is T - 1/4.

When Allen and Danny work together, their combined rate is X = 1 / (1/8 + 1/16) = 4/7.

The total time taken by them to finish the remaining work is (T - 1/4) / (4/7) = (7/4) * (T - 1/4) = 7T/28 - 7/28.

So, the total time taken to build the fence is 2 + (7T/28 - 7/28) = 2 + 7T/28 = T.

Therefore, T = 2 + 7T/28 = 2 + 7 * (8 hours) / 28 = 2 + 4 hours = 6 hours.

If one side and two angles of a triangle are known, the triangle can be solved Law of Sines.

If A, B, and C are the measurements of the angles of a triangle, and a, b and c are the lengths of the sides opposite of the corresponding angles, then the ratio of side length to the sine of the opposite angle must all be the same.

                                      a/SinA = b/SinB = c/SinC

So, let's say that the value of 'a' is given and the value of angles A and B are also given. By using the law of sine, we can determine the value of 'b' as follows:

                                      a/SinA = b/SinB

                                      b = (a/SinA) SinB

In mathematics, the slope or gradient of a line is a number that describes both the direction and the steepness of the line. The slope of a line is a measure of its steepness. Mathematically, slope is calculated as "rise over run" (change in y divided by change in x).

here, we have,

the mid-point of the line joining (1,2) and (3,4) is,

(1+3/2, 2+4/2)

=(2, 3)

slope= 3 =m

Therefore, the r value alone is not enough to infer causality, regardless of its magnitude.

The correlation coefficient, also known as the Pearson correlation coefficient or Pearson's r, is a measure of the strength and direction of the linear relationship between two continuous variables. It is expressed as a number between -1 and 1, where -1 indicates a perfect negative correlation (meaning that as one variable increases, the other decreases), 1 indicates a perfect positive correlation (meaning that as one variable increases, the other also increases), and 0 indicates no correlation. The value of the correlation coefficient provides information about how closely the two variables are related, but it does not establish causality.

The r value alone is not enough to infer causality. A high correlation coefficient suggests a strong relationship between two variables, but causality means that one variable is causing the changes in the other variable and requires a causal mechanism and a demonstration of a temporal relationship between the variables.

The diameter of the Earth would need to be approximately 3,548.896 km to appear the same size as the Sun from the Moon.

A ratio in mathematics is a comparison of two or more numbers that shows how big one is in comparison to the other. The dividend or number being divided is referred to as the antecedent, while the divisor or number that is dividing is referred to as the consequent.

Let's call the diameter of the Earth "d".

From the Moon, the Earth is at a distance of 384,400 km,

and the Sun is at a distance of 149,600,000 km.

The ratio of the Sun's diameter to its distance from the Moon is

= 1,391,000 km / 149,600,000 km

= 0.00928.

So, to make the Earth appear the same size as the Sun, we need the ratio of the Earth's diameter to its distance from the Moon to be equal to 0.00928.

d / 384,400 km = 0.00928

Solving for d, we get:

d = 384,400 km x 0.00928

Answer: D

Step-by-step explanation:

45-4=41

45+4=49

Based on the given estimate that the candidate will receive 45% of the votes and the margin of error being 4%, the most appropriate conclusion would be option C:

The candidate will receive between 45% and 49% of the votes. To understand why this is the most appropriate conclusion, we need to consider the concept of margin of error. The margin of error is a measure of the uncertainty in the estimate and represents the range within which the true value is likely to fall. In this case, we have an estimated proportion of votes (45%) and a margin of error (4%).

To calculate the range within which the true value is likely to fall, we add and subtract the margin of error from the estimated proportion. Upper bound: [tex]45 + (4 of 45) = 45 + 1.8% = 46.8[/tex]  

Lower bound: [tex]45 - (4 of 45) = 45 - 1.8 = 43.2[/tex] %

Therefore, we can conclude that the candidate is likely to receive between 43.2% and 46.8% of the votes. Option C, which states that the candidate will receive between 45% and 49% of the votes, aligns with this conclusion. Option B (between 41% and 45%) is too conservative as it does not account for the upper bound of the margin of error,

Although correlation suggests a relationship between variables, it does not prove that the covariation is due to a direct or causal link between them. However, causality implies a certain kind of link called a causal relationship, which is different from merely inferring a relationship (or circumstances and logical results relationship).
