Answer:
D= 3.9 milesStep-by-step explanation:
Given data
speed v= 13 miles per hour
time taken t= 20min to hour 0.3 hours
the distance D
We know that the relationship between speed, time, and distance
speed=distance/time
13=D/0.3
(the expression above describes the relationship between distance, speed, and time)
making D subject of formula we have
D= 0.3*13
D= 3.9 miles
hence the distance is 3.9miles
Answer:
If your looking for the equation it will be
D = 13 · 1/3
And the answer to this equation is 3.9 miles

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
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.

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

Additional Q1. Below is the structure of a high abundant in human milk that helps infants to fight viral infection. Identify the 3 monosaccharides (for example Gal, Glc, etc), and the 2 glycosidic bonds (e.g. β1 4). also name the trisaccharide (e.g. Gal β1−4Glcα1−3Glc ). 3 Points
The trisaccharide present in high abundance in human milk that helps infants fight viral infection is Lacto-N-fucopentaose III (LNF-III).
It consists of three monosaccharides: fucose, galactose (Gal), and N-acetylglucosamine (GlcNAc). The glycosidic bonds present in LNF-III are β1-3 and α1-4.
LNF-III plays a crucial role in the innate immune defense of infants against viral infections. The monosaccharide fucose is attached to the Gal-GlcNAc disaccharide unit through a β1-3 glycosidic bond, forming the backbone of the trisaccharide. This structure is further extended with an α1-4 glycosidic bond between the Gal and GlcNAc residues. The presence of LNF-III in human milk is significant because it acts as a receptor for certain viruses, such as norovirus and rotavirus, which commonly affect infants. These viruses specifically bind to the fucose residue of LNF-III, preventing their attachment to host cells and subsequent infection. Therefore, the abundance of LNF-III in human milk provides a natural defense mechanism for infants against viral pathogens. In summary, the trisaccharide Lacto-N-fucopentaose III (LNF-III) found in human milk contains the monosaccharides fucose , galactose (Gal), and N-acetylglucosamine (GlcNAc). It is formed by a β1-3 glycosidic bond between fucose and the Gal-GlcNAc disaccharide unit, and an α1-4 glycosidic bond between galactose and N-acetylglucosamine. LNF-III serves as a receptor for certain viruses, preventing their attachment to host cells and aiding in the infant's defense against viral infections.

Question# 1: For what values of 'a', the vector a² a is in span 1 1 1 ELEME 2 1 3 3 4
The vector [a², a] is in the span of [1, 1, 1] and [2, 1, 3] if and only if 'a' can be expressed as a linear combination of the given vectors. Thus, the vector [a², a] is in the span of [1, 1, 1] and [2, 1, 3] when a is either 0 or 2.
To determine the values of 'a' for which the vector [a², a] is in the span of [1, 1, 1] and [2, 1, 3], we need to check if there exist constants x and y such that:
x[1, 1, 1] + y[2, 1, 3] = [a², a]
This leads to the following system of equations:
x + 2y = a²
x + y = a
Solving this system, we find:
x = a - y
Substituting this value into the first equation:
a - y + 2y = a²
y = a² - a
Now, we substitute the value of y back into the equation for x:
x = a - (a² - a)
x = 2a - a²
Therefore, for the vector [a², a] to be in the span of [1, 1, 1] and [2, 1, 3], 'a' must satisfy the equation:
2a - a² = a(2 - a) = 0
This equation has two solutions: a = 0 and a = 2. Thus, the vector [a², a] is in the span of [1, 1, 1] and [2, 1, 3] when a is either 0 or 2.

A recipe says that 6 spring rolls will serve 3 people. Complete the table as you answer the questions. Be prepared to explain your reasoning.
a) Complete the table.
b) Explain HOW you completed the table in words or by making your math thinking visible by sketching on the table.
Answer:
Step-by-step explanation:
b). Since relation between the number of spring rolls and number of people is,
Number of spring rolls ∝ Number of people
Therefore, Number of spring rolls (R) = k × Number of people (P)
With the help of this proportional relation,
If the number of spring rolls (R) are 6 and the number of people (P) are 3.
6 = 3k
k = 2
So the equation that defines the relation will be,
R = 2P
a). For R = 1,
1 = 2P ⇒ P = 0.5
For R = 10,
10 = 2P ⇒ P = 5
For R = 16,
16 = 2P ⇒ P = 8
For R = 25,
25 = 2P ⇒ P = 12.5
For R = n,
n = 2P ⇒ P = [tex]\frac{n}{2}[/tex]

The equation for the total cost of the gym membership over t months is
C = 100 + 50t.
What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,

The total cost of the membership after 2 months.
= $200
This means,
The cost per month.
= (200 - 100) ÷ 2
= 100 ÷ 2
= 100/2
= $50
The cost of the gym membership over t months.
= 100 + 50t
Thus,
The equation is C = 100 + 50t.
