Joan performed an experiment on two different types of cells and noted their sizes as follows:
Cells Size
Cell A 0.0005×10−5 m
Cell B 0.0025×10−7 m
What is the ratio of the size of cell A to the size of cell B?
Answer: Press this link to get your answer -)
Step-by-step explanation:
The ratio is simply the fractional representation of two values in their simplest form. The ratio of Cell A to Cell B is 20 which means that the size of Cell A is 20 times the size of Cell B.
Given that :
Cell size A = [tex]Cell A = 0.0005\times 10^{-5}\\\\Cell B = 0.0025\times10^{-7} \\\\Ratio = \frac{Cell A }{Cell B} \\\\Ratio = \frac{0.0005 \times 10^-5}{0.0025 \times 10^-7}[/tex]
[tex]Ratio = 20[/tex]
Therefore, the ratio of the size of Cell A to the size of Cell B is 20 : 1, which can be interpreted to mean that cell A is 20 times larger than cell B.

What is an equation for the line in slope-intercept form perpendicular to y = -14x – 2 that contains (–3, 1)
Answer:
y= 1/14 x +17/14
Step-by-step explanation:
Lines perpendicular to another line have an opposite reciprocal slope, meaning that the sign is changed, and the fraction is flipped. We are going to use point-slope form to solve.
[tex]y-y_{1} =m(x-x_{1} )\\y-1 =\frac{1}{14} (x+3 )\\y-1=\frac{1}{14}x+\frac{3}{14}\\y=\frac{1}{14}x+\frac{17}{14}[/tex]

Identify the independent and dependent variables. Then write a rule in function notation for the situation, letting x represent the independent variable.
A concert ticket costs $60.
Answer:
independent: number of tickets purchased;
dependent: total cost;
rule: f(x) = 60x
Step-by-step explanation:
The independent variable is the input of a function (the variable whose value determines the value of the output, or dependent variable). In this case, the independent variable is the number of tickets purchased.
The dependent variable is the output of a function (the variable whose value depends on the value of the input, or independent variable). In this case, the dependent variable is the total cost of all tickets purchased.
The total cost of all tickets purchased is equal to $60 times the number of tickets x. Therefore, a function rule for the total cost of all tickets purchased is f(x) = 60x.

Use the slope formula to find the slope between the given two points?
(2, 1) and (8,9)
Answer:
4/3
Step-by-step explanation:
Slope = (y2-y1)/(x2-x1)
(9-1)/(8-2)
4/3
Answer:
[tex]\frac{4}{3}[/tex]
Step-by-step explanation:
(2,1) (8,9)
The formula that you would use is:
[tex]\frac{y_{2}-{y_1} }{x_2-x_1}[/tex]
So, 2 could be [tex]x_1[/tex] and 1 could be [tex]y_2[/tex]
and 8 could be [tex]x_2[/tex] and 9 could be [tex]y_2[/tex]
When we insert these numbers into the equation, we get:
[tex]\frac{9-1}{8-2}[/tex]
When we solve that we get:
[tex]\frac{8}{6}[/tex]
Now we simplify it by dividing both the numerator and denominator by 2, which would give us:

Oth John's parents and Marco's parents decide to start a college fund for their children. The expressions below represent the value of each college fund after w weeks. John's College Fund: 43 w + 1814 12 Marco's College Fund: 25 w + 1744
Answer:
Step-by-step explanation:
The question is not clear on what to solve for, but we can solve for the number of weeks in which the two funds will have the same amount.
let the total fund funds be y
and the number of weeks be w
For John's fund the expression is
y=45w+1814------1
Marco's College Fund
y=25 w+1744---------2
equating 1 and 2 we have
45w+1814=25w+1744
45w-25w=1744-1814
20w=-70
divide both sides by 20 we have
w=-70/20
w=-3.5
this means that in 3 and half weeks the two funds will have the same amount in them

Hiroaki says that a constant of proportionality must be a whole number and cannot be a fraction or a decimal. Explain why Hiroaki is incorrect.
Hiroaki is mistaken since the line should pass through the origin, negating the possibility of the proportionality constant being a simple whole number.
What are Whole Numbers?Whole numbers are defined as natural numbers plus zero (0). We are aware that the term "natural numbers" refers to a group of counting numbers beginning with 1, 2, 3, 4, and so forth. Whole numbers are a collection of numbers that don't contain any fractions, decimals, or even negative integers. It is made up of zero and positive integers. Alternately, we may define whole numbers as the collection of non-negative integers. The inclusion of zero in the set of whole numbers marks the main distinction between them and natural numbers.
What is a fraction?An element of a whole is a fraction. The number is represented mathematically as a quotient, where the numerator and denominator are split. Both are integers in a simple fraction. A fraction appears in the numerator or denominator of a complex fraction. The numerator of a proper fraction is less than the denominator.
What is a decimal ?A decimal is a number that is divided into two parts: a whole and a fraction. Between integers, decimal numbers are used to express the numerical value of complete and partially whole quantities.
