Every package of a certain toy also includes 2 batteries.
1. Are the number of toys and the number of batteries in a proportional relationship? If so, what are the two constants of proportionality? If not, explain your reasoning.
2. Use t for the number of toys and b for the number of batteries to write two equations relating the two variables.
b=
t=
Answer:
1) Yes, 1/2 and 2
2) b=1/2 × t
t=2 × b
Step-by-step explanation:
1) Yes, because every package of a toy equals 2 batteries. The constant of proportionality is 1/2 and 2 because 1 ÷ 2 = 1/2 and 2 ÷ 1 = 2 (amount of toys divided by amount of batteries and vice versa)
2) b = 1/2t, because for every battery, there is 1/2 a toy.
t = 2b, because for every toy, there are 2 batteries
note: you can't actually have 1/2 a toy, but we write it like that for the sake of showing the relationship of toy to battery.

The human body is made up of about 37.2 trillion blood cells. That’s a lot of blood cells! Instead of writing 37,200,000,000,000 to express this very large number, we use scientific notation to write it as 3.72 × 1013.
A. Research to find another large or small number from a real-world situation. Write the number in scientific notation. Provide a hint that describes what your number represents.
B. Read another student’s post and guess what that student's number describes. Then write the number in standard form. Try to choose a post that doesn’t have any responses to it yet.
C. Respond to all replies to your post. For each post, check whether the number is correctly written in standard form and whether the student correctly guessed what your number represents. At the close of the discussion, reveal the answer.

The coefficient of the x term in the product after simplifying [tex](-x-5)^{2}[/tex] is 10.
Given an expression in terms of product [tex](-x-5)^{2}[/tex]
We are required to find the coefficent of the term x in the given product expressed as an expression.
Expression is a combination of numbers,symbols, fraction, coefficients, determinants,indeterminants. It is usually not found in equal to form. It shows a relationship between variables.
The given expression is [tex](-x-5)^{2}[/tex].
We can write [tex](-x-5)^{2}[/tex] as (-x-5)(-x-5) and now multiply each other.
=-x*(-x)-x*(-5)-5*(-x)-5*(-5)
When two negative values are multiplied then they will result in positive number.
=[tex]x^{2} +5x+5x+25[/tex]
=[tex]x^{2} +10x+25[/tex]
Because 10 is present with x so the coefficient of term x is 10.
Hence the missing coefficient of the x term of the product [tex](-x-5)^{2}[/tex]
is 10.

The total cost in dollars, y, of a membership at each of four health clubs is represented below in terms of x, the number of months of the membership. Which representation is a proportional relationship
Select one:
Health Club C
Health Club D
Health Club A
Health Club B
Answer:health club B
Step-by-step explanation:
The representation that is a proportional relationship is the table of values representing Helath Club B.
What is a Proportional Relationship?If a relationship between two variables, x and y, is proportional, the equation of the relationship would be y = mx, where m is the constant rate.
Constant rate/unit rate (m) = y/x
The graph of a proportional relationship is a straight line graph that passes through the origin (0,0).
Thus, the equation of Club A is not a proportional relationship equation.
The line graph for Club C doesn't pass the origin.
For Club B, we have:
Unit rate (m) = 21/1 = 42/2 = 21.
Therefore, the table for Cub B represents a proportional relationship.

Sixteen is the same as one and two-tenths times a number added to negative 8.
16 + 1.2 n = negative 8
16 + 1.2 n = 8
16 = 1.2 n + (negative 8)
16 = negative 1.2 n + 8
Answer:
I would say 16=1.2n+(negative 8) because they are in the same order as it was spelled in words and not numbers that's how I know that it could be 16=1.2n+(negative 8).

Does the size of a circular object affect the relationship between its circumference and its diameter?
A. The size will affect the relationship between circumference and diameter because of circumference changes at a greater rate than the diameter.
B. The size has no effect on the relationship between circumference and diameter because the ratio is always equal to
C. The size has no effect on the relationship between circumference and diameter because the two values change independently.
D. The size will affect the relationship between circumference and diameter because of the value changes as the circumference changes.
Answer: A
Step-by-step explanation: It doesn't. The circumference of a circle is 2*pi*radius and the diameter is 2*radius, so the circumference divided by the diameter is pi, which is the ratio of circumference to diameter.

Employees at a company are given £1,400 to spend on items for the office.
They decide to buy a coffee machine and as many bean bags as possible.
Bean bags cost £45 with an offer of "Buy at least 10 get 10% off the price."
The coffee machine costs £320.
How much will they have left over from the £1,400?
9514 1404 393
Answer:
£27
Step-by-step explanation:
If we assume that more than 10 bean bags will be purchased, their individual cost will be £45 - 10%×£45 = £40.50. Then the total cost of n beanbags and a coffee machine will satisfy the inequality ...
£40.50n +£320 ≤ £1400
40.50n ≤ 1080
n ≤ 26 2/3 . . . . . . . 26 is more than 10, so the discount will be applied
Only an integer number of beanbags can be purchased, so the purchase of 26 beanbags and the coffee machine will leave a left-over amount of ...
£1400 -(320 +26×40.50) = £1400 -1373 = £27
The employees will have £27 left over.
Answer:
The answer is £27.
