which of these is a factor in this expression?
7z^4-5+10(y^3+2)

Answers

The expression [tex]7z^4 - 5 + 10(y^3 + 2),[/tex] the factor is "10" since it multiplies the expression [tex](y^3 + 2)[/tex] to contribute to the overall product.

In the expression [tex]7z^4 - 5 + 10(y^3 + 2),[/tex] the term "10" is a factor.

To understand factors in this context, let's define them.

In algebra, factors are expressions or numbers that are multiplied together to obtain a product.

In the given expression, we have three terms: [tex]7z^4, -5,[/tex] and [tex]10(y^3 + 2).[/tex]

The term "10" is a factor because it is multiplied by the expression [tex](y^3 + 2).[/tex]

When we distribute 10 to the expression inside the parentheses, we get 10y^3 + 20.

Thus, "10" serves as a factor in the overall expression.

However, it's important to note that the term "-5" is not considered a factor because it is not being multiplied by any other expression or number.

It is a standalone constant term.

X = 12

Step-by-step explanation:

Basically, just start with 11 and do all of the steps backwards, so multiply 11 by 5, which is 55, then add 2, 57. divide by 3, which is 19, then subtract 7, and you'll get the original number, 12.

Answer:

x = 12

Step-by-step explanation:

Following the steps in the flowchart

(1) Input the number x

x

(2) Add 7

x + 7

(3) Multiply by 3

3(x + 7)

= 3x + 21

(4) Subtract 2

3x + 21 - 2

= 3x + 19

(5) Divide by 5

[tex]\frac{3x+19}{5}[/tex]

(6) Output the number 11

[tex]\frac{3x+19}{5}[/tex] = 11 ( multiply both sides by 5 )

3x + 19 = 55 ( subtract 19 from both sides )

3x = 36 ( divide both sides by 3 )

x = 12

Martin is building a model .he cuts two pieces of wood taht are each 6, 1/3 inches long from a board with a total length of 18 inches .what is the length, in inches, od the remaining part of the boards

Answers

Answer:

Step-by-step explanation:

6 1/3 + 6 1/3 = 12 2/3 + 5 1/3 = 18

The remaining part of the wood is 5(1/3) out of a total length of 18 inches.

What is an expression?

Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given that Martin is building a model he cuts two pieces of wood that are each 6, 1/3 inches long from a board with a total length of 18 inches.

The remaining part will be calculated as below:-

Length of the two parts = 6(1/3) + 6(1/3)

                                       = 12(1/3)

The remaining part will be calculated as,

R = 18 - 12(1/3)

  = 5(1/3)

Therefore, the remaining part of the wood is 5(1/3) out of a total length of 18 inches.

If the interest rate on a nominal bond is 9% today for three years when expected inflation is 2% on average, what is the real interest rate paid at the end of the three years if actuall inflation was

Answers

The real interest rate paid at the end of three years can be calculated by subtracting the average inflation rate from the nominal interest rate. In this case, with a nominal interest rate of 9% and an average expected inflation rate of 2%, the real interest rate would be 7%.

The real interest rate is the nominal interest rate adjusted for inflation, representing the true return on an investment. To calculate the real interest rate, we subtract the average inflation rate from the nominal interest rate. In this scenario, the nominal interest rate is 9% and the average expected inflation rate is 2%.

By subtracting 2% from 9%, we find that the real interest rate paid at the end of the three years is 7%. This means that after accounting for inflation, the investor can expect a real return of 7% on their investment over the three-year period.

Considering inflation is essential because it erodes the purchasing power of money over time. By accounting for inflation, the real interest rate provides a more accurate measure of the return on investment. In this case, the real interest rate of 7% indicates that the investor is effectively earning a 7% return above and beyond the rate of inflation, providing a positive real return.

The piston moves from the Top dead center as a result of a change * crank angle ratio of crank radius to connected length connected length crank radius the distance from TDC to the crank center equal to * a=crank radius b= connected length a*b a+b. the piston travel changed with * connected rod length crank angle R/L crank radius 2 points 2 points 2 points

Answers

The piston travel in an engine is influenced by the crank angle, crank radius, and connected rod length. The relationship between these variables is described by the formula a + b, where a represents the crank radius and b represents the connected rod length. The piston travel is directly related to the change in crank angle and is affected by the ratio of crank radius to connected rod length.

In an engine, the motion of the piston is driven by the crankshaft, which converts the rotational motion of the crank into linear motion of the piston. The distance traveled by the piston from the Top Dead Center (TDC) is influenced by various factors, including the crank angle, crank radius, and connected rod length.
The crank angle represents the angle through which the crankshaft rotates. As the crankshaft rotates, the piston moves up and down in the cylinder. The change in crank angle directly affects the piston travel.
The crank radius (a) is the distance from the center of the crankshaft to the point where the connecting rod is attached. The connected rod length (b) is the distance from the attachment point on the crank to the attachment point on the piston. The sum of the crank radius and the connected rod length, represented by a + b, determines the piston travel.
The ratio of crank radius to connected rod length also plays a role in the piston travel. This ratio affects the motion of the piston and determines the relationship between the crank angle and the linear displacement of the piston.
In summary, the piston travel in an engine is determined by the change in crank angle and is influenced by the ratio of crank radius to connected rod length. The formula a + b, where a represents the crank radius and b represents the connected rod length, describes the relationship between these variables. By understanding these factors, engineers can optimize the design and performance of internal combustion engines.
