The direct proportion y=kx is given in the following table. Find the coefficient k, and fill in the table:
Answer:
Look at image
Step-by-step explanation:
image shown below, copy the answer from there.
The value of coefficient k is 5. The required values are y = 15.5 when x = 3.1, y = 12.5 when x = 2.5, y = 6 when x = 1.2, y = 4.5 when x = 0.9, x = 0.06 when y = 0.3, and x = 0.02 when y = 0.1.
What is the equation?The term "equation" refers to mathematical statements that have at least two terms with variables or integers that are equal.
The direct proportion y = kx is given in the shown table.
Find the coefficient k, and fill in the table:
As per the question, we have
y = kx .....(i)
To determine the value of k, we substitute the value of x = 0.14 and y = 0.7 in equation (i),
⇒ 0.7 = k (0.14)
⇒ k = 0.7/0.14
⇒ k = 5
Substitute the value of k = 5 in equation (i), and we get
y = 5x .....(ii)
Now, we are finding the values of the table,
Substitute the value of x = 3.1 in equation (ii), and we get
y = 5(3.1)
y = 15.5
Similarly, the other required values are
y = 12.5 when x = 2.5, y = 6 when x = 1.2, y = 4.5 when x = 0.9, x = 0.06 when y = 0.3, and x = 0.02 when y = 0.1.

Linda made 24 jelly-bread sandwiches with a 16-ounce jar of jelly.
Joanne made 30 jelly-bread sandwiches with a 20-ounce jar of jelly.
Who used more ounces of jelly per sandwich, Linda, Joanne, or both? Explain your reasoning.
(Hint: Find the ounces per sandwich for each person, then compare.)
Answer:
Both of them made the same
Step-by-step explanation:
find each ounce of jelly per sandwich
for Linda - 24/16 = 1.5
for Joanne - 30/20 = 1.5
so for each sandwich, both used 1.5 ounce of jelly

A gallery owner purchased a very old painting for 3000 dollars. The painting sold for 325 percent increase in price. What is the retail price of the printing?
Answer:
$12,750
Step-by-step explanation:
The price at purchase = 3000 dollars
Sale = 325 percent increase in purchase price.
325% = 3.25
3.25x3000 = 9750 dollars
So, at 325 percent increase in price, this painting sold for $9750.
The retail price of this painting =
Price at purchase + price during sale
= 3000 + 9750
= $12,750
Therefore the retail price is equal to $12,750

2. What is the perimeter of the rectangle?
Answer:
The area is 28 cm squared.
The perimeter is 22 cm.
Step-by-step explanation:
To find the area, multiply one side length by the other.
7x4 = 28 cm^2
To find perimeter add the four sides of the rectangle.

The rule of 72 is used to determine how long it will take an investment to . For an investment of $5,000 earning 7% annually, this will take about years.
Answer:
10.3 years
Step-by-step explanation:
The Rule of 72 is a rule used to determine the period of time it would take an investment to double at a given fixed annual rate of return. The rule of 72 helps investors to have an estimate of how long an initial investment would double. The rule of 72 is given by the formula:
t = 72 / r
where r is the annual rate of return and t is the approximate time in years required for the investment to double.
t = 72 / r
Given that r = 7%
t = 72 / r = 72 / 7 = 10.3 years
Therefore it would take 10.3 years for an investment of $5,000 earning 7% annually to double to about $10,000

Which relation is a function?
Answer:
A function is a relation in which each input has only one output. In the relation , y is a function of x, because for each input x (1, 2, 3, or 0), there is only one output y. x is not a function of y, because the input y = 3 has multiple outputs: x = 1 and x = 2.

Step-by-step explanation:
We use negative integer to represent loss, below , or withdrawal etc.
On the other hand we use positive integers to show gain , above , deposit etc.
Given statement : The outdoor temperature is 4 degrees below 0.
So we will represent it by -4 degrees.
The indoor temperature is 72 degrees above 0.
So we will represent it by +72 or 72 degrees.
