Which situation can be modeled by the equation y = mx + b? A. The number of bacterial cells (y) in a Petri dish doubles every hour (x).
B. The time (y) it takes to fill an 80-gallon bathtub depends on the number of gallons filled per minute (x).
C. The total cost (y) of publishing a textbook at a printing cost of $9.50 per book depends on the number of books (x) published.
D. The volume (y) of a conical flask with a height of 6 inches depends on the radius (x) of the flask.

Answers

Answer 1

Answer:

We have to check which of the statements can be modeled as y = mx + b. This equation represents a straight line or is a linear equation. Hence, in the given options we will check which statement represents a linear equation.

Statement A: The number of bacterial cells (y) in a Petri dish doubles every hour (x).

This can be expressed as y (x) = y (x-1) * 2, which is not a linear function. Refer attached image

Statement B: The time (y) it takes to fill an 80-gallon bathtub depends on the number of gallons filled per minute (x).

Here, we can not determine the expression and we just know that the time (y) is a function of number of gallons filled per minute (x).

Statement C: The total cost (y) of publishing a textbook at a printing cost of $9.50 per book depends on the number of books (x) published.

This can be expressed as y = 9.5 * x. This is a linear function, which will grow by a factor of 9.5 with each unit change in x. Refer attached image.

Statement D: The volume (y) of a conical flask with a height of 6 inches depends on the radius (x) of the flask.

Here, we can not determine the expression, but we know that the volume of a cone with 6 inch height is a function of the cone's radius.

Hence, statement C can be modeled by the equation y = mx + b.

Answers

There we multiply by 6 because there are six sides in a polygon
6* (2.6*3/2)
= 6* 3.9
= 23.4
Therefore the answer will be option b (23.4)

A sheet of standard size copy paper measures 8.5 inches by 11 inches. If a ream is 500 sheets of paper has a volume of 187 inches cube. How thick is the ream?

Answers

Answer:

\large \boxed{\text{2.00 in}}

Step-by-step explanation:

The formula for the volume of a rectangular solid is

V = lwh

$\begin{array}{rcl}V & = & lwh\n187 & = & 8.5 * 11 * h\n& = & 93.5h\nh & = &(187)/(93.5)\n\n& = & \textbf{2.00 in}\n\end{array}\n\text{The ream is $\large \boxed{\textbf{2.00 in}}$ thick.}$

How many inches is 100 meters

Answers

There is 3937.01 inches in 100 meters.
There is 39.3701 inches in 1 meter
multiply that by 100 and you get your answer
Hope This Helps

There are approximately 2.5 centimeters in one inch. and there are 100 centimeters in 1 meter. So if you divide 100 by 2.5, to you get approximately how many inches there will be in one meter.
100÷2.5=40
So your answer should be 40. hope this helped! :)

Shilpa bought 30 T-shirt at a clothing store. 20% of the t-shirt were blue and 1/2 of the t-shirts were black. Howmany of the t-shirts were neither black nor white?

Answers

The number of T-shirt bought by Shilpa from a clothing store = 30
Percentage of T-shirt that were blue = 20%
Then Number of T-shirt that were blue in color = (20/100) * 30
   = 2 * 3
   = 6
Number of T-shirts that were black in color = (1/2) * 30
   = 15
Then
The total number of T-shirts that were black and blue = (15 + 6)
   = 21
Then
The total number of T-shirts that were neither black nor blue = 30 - 21
   = 9
So the number of T-shirts that were neither black nor blue was 9.
