# Each veterinarian has seen 40 animals today. Two out of every 5 animals Vet A has seen have been dogs. Three out of every 8 animals Vet B has seen have been dogs. Which vet saw more dogs today? Explain your reasoning.

QUESTION POSTED AT 14/12/2019 - 05:23 PM

Basically, the fractions are 2/5 vs. 3/8. As always, in order to compare fractions, you must first have a common denominator. The easiest way to achieve that is by multiplying the two denominators by each other. 5*8=40. You must also multiply the numerators by the same thing you multiplied the denominators by, so 3*5=15, and 2*8=16. The new fractions are 16/40 vs. 15/40. Therefore, Vet A has seen more dogs.

D. The expression is . It takes 40 minutes to shape and fire 10 pots.

Step-by-step explanation:

Let the number of pots in a batch = p

Now, one pot takes 3 minutes to get in a shape.

Then, 'p' pots will take minutes to get in a shape.

Also, it takes 10 minutes to fire one batch of pots.

Thus, the expression for the time taken to form one batch of pots =

So, when number of pots = 10 i.e. p= 10.

Time taken to fire the pots = = 30+10 = 40

That is, 'It takes 40 minutes to shape and fire 10 pots'.

Thus, option D is correct.

A.Two students are the same age but have different heights. B.Two students have the same height but different ages. C.No two students are the same age or height.

Option: A is the correct answer.

A.  Two students are the same age but have different heights.

## Step-by-step explanation:

The height of a student could not be a function of the ages of a student because two or more students with the same age may have the different heights .

This means that a value on a x-axis (i.e.  age) is mapped to two or more  values i.e. corresponding y-value ( i.e.  different heights) which violates the definition of function.

Hence, option: A is the correct answer.

### A candy bar box is in the shape of a triangular prism. The volume of the box is 3,240 cubic centimeters. A triangular prism is shown with base of triangle labeled 24 cm, sides of the triangle labeled 15 cm, and length of the box equal to 30 cm. Part A: What is the height of the box? Show your work. (5 points) Part B: What is the approximate amount of cardboard used to make this candy box? Explain how you got your answer.

Part A - 9 cm; Part B - 1836 cm²

Step-by-step explanation:

Part A:  The volume of a triangular prism is given by the area of the base (area of the triangle) multiplied by the length of the box.  To find the area of a triangle, we use the formula A = 1/2bh; this gives us

V = 1/2bhl

Using the information we have gives us

3240 = 1/2(24)(h)(30)

3240 = 360h

Divide both sides by 360:

3240/360 = 360h/360

9 = h

Part B:  We are looking for the surface area of this prism.

There are two triangular sides, each with a base of 24 and a height of 9.  Their areas are:

A = 1/2bh = 1/2(24)(9) = 108 sq cm each.  For two of them, this makes

108(2) = 216 sq cm

There are two rectangular sides whose dimensions are 15 by 30; their areas are

A = 15(30) = 450.  For two of them, this makes

450(2) = 900 sq cm.

There is one rectangular side whose dimensions are 30 by 24.  Its area is

A = 30(24) = 720 sq cm.

This makes the total surface area

216+900+720 = 1836 sq cm.

A petri dish is simply a circle; thus, we use the formula of the area of the circle which is πr^2.
Given r = 40 mm
A =
π(40)^2 = 5026.55 sq. mm

Population density = bacteria count / area
PD = 2,100 / 5026.55
PD =

Tom has one part-time employee who works 20 hours per week. Each full-time employee works 40 hours per week. Write an inequality to determine n, the number of full-time employees Tom must schedule, so that his employees will work at least 260 person-hours per week.

Step-by-step explanation:

Given :

Tom needs to schedule employees to staff the deli department at least 260 person-hours per week.

Tom has one part-time employee who works 20 hours per week.

Each full-time employee works 40 hours per week.

To Find: An inequality to determine n, the number of full-time employees Tom must schedule, so that his employees will work at least 260 person-hours per week.

Solution :

Suppose that there are n number of full time employees.

Since each full time employee work for 40 hours per week .

So, n full time employees work for 40*n =40 n hours per week

And we are given that he  has one part-time employee who works 20 hours per week. so, this part time employee hours are fixed .

Since ,  Tom needs to schedule employees to staff the deli department at least 260 person-hours per week.

Thus inequality becomes :

Hence the inequality to determine n, the number of full-time employees Tom must schedule, so that his employees will work at least 260 person-hours per week :

Let's take one side of the two equal lengths as r
third side is s.
so the total perimeter is r + r + s
2r + s = 23

According to the statement of third side s,
5 less than twice the length of one of other
s = 2r - 5

we have 2 equations and 2 unknowns. so we can find out the values of those letters.

2r + s = 23
2r - s = 5

4r = 28
r = 7

s = 9
Therefore the third length will be equal to 9 cm.

By definition, a linear equation in its standard form is given by:

Where,
m: slope of the line
b: cut point with the y axis (occurs when x = 0)
The value of m, b is constant.
Therefore, the value of the rate of change of the function, which is represented by the slope of the line, is constant.
This means that for each value of x, the value of the function increases m times.
