Answers

Answer: The expression (equation/formula) for the volume of a:  

     " right rectangular prism " ;   is represented by:

____________________________________________________

                    →   " V  =  L * w * h  "   ;

____________________________________________________

in which:   all the dimensions are in the same "units of measurement" (or converted to the same "units of measurement" ;  

and in which:

      " V " is the "volume" of the right rectangular prism; in the "cubic units" ; or written as:  "units³ "  ;  or, [insert the particular units used}^ ³  "   ;

  →  that is, [units] raised to the "3rd [third] power" ; assuming these units are the same  same "fundamental units of measurement"  as the "other 2 (two) values in the expression".  

    If we are given no specific units of measurement whatsoever, then we use the generic term, "units" as the "units of measurement" ; and we express the "volume; "V" ;  of a "right rectangular prism" as:  " units ³ " ; or "cubic units" ;

        in our answer— if we are asked to solve for the:

                     "volume; "V";  of a "right rectangular prism" ;

_________________________________________________

and in which:  

            "L" represents the "length" of a "right rectangular prism" ;

            "w" represents the "width" of a "right rectangular prism" ;

            "h" represents the "height" of a "right rectangular prism" .

_________________________________________________

To given an example:

  Say we have a "right rectangular prism" ; with the given measurements:

    width , "w" :   w = 2 units;  

    length, "L"  :    L  = 3 units ;

    height, "h" :    h =  8 units.

_________________________________________________

We are asked to "find the volume " ;  of this "right recentangular prism" .

The formula for the volume;  "V" ;  of this "right rectangular prism" ;

is:

_________________________________________________

          →    Volume  =  Length * width * height ;

that is:

          →    V =  L  * w * h  ;  

Solve for the volume;  "V" .

_________________________________________________

          →   V  =  L  * w * h   ;    Now plug in the values given:

          →   V =  (3 units)  * (2 units)  * (8 units) ;

                   

                    =  3 * 2 * 8 * (units) * (units) * (units) ;

                    =  3 * 2 * 8 * units ³  ;

                    =  48 units ³ .

Answer: A

Step-by-step explanation:

I filled 6/9 of the prescriptions for the pharmacist to review. The pharmacist returns and reviews 2/3 of the prescriptions. How many more prescriptions does the pharmacist have left to review that I filled?

Answers

[tex]\left(1-\dfrac{2}{3}\right)\cdot\dfrac{6}{9}=\dfrac{1}{3}\cdot \dfrac{2}{3}=\dfrac{2}{9}[/tex]

The pharmacist has 2 more prescriptions left to review that you filled.

To find out how many prescriptions the pharmacist has left to review, we can follow these steps:

1. Calculate the total number of prescriptions filled by you:

[tex]\[ \text{Total filled prescriptions} = \frac{6}{9} \times \text{Total prescriptions} \][/tex]

2. Calculate the number of prescriptions reviewed by the pharmacist:

[tex]\[ \text{Prescriptions reviewed by pharmacist} = \frac{2}{3} \times \text{Total filled prescriptions} \][/tex]

3. Calculate the number of prescriptions left for the pharmacist to review:

[tex]\[ \text{Prescriptions left to review} = \text{Total filled prescriptions} - \text{Prescriptions reviewed by pharmacist} \][/tex]

Let's put the numbers into these equations. Assuming there were initially 9 prescriptions:

1. Total filled prescriptions:

[tex]\[ \text{Total filled prescriptions} = \frac{6}{9} \times 9 = 6 \][/tex]

2. Prescriptions reviewed by pharmacist:

[tex]\[ \text{Prescriptions reviewed by pharmacist} = \frac{2}{3} \times 6 = 4 \][/tex]

3. Prescriptions left to review:

[tex]\[ \text{Prescriptions left to review} = 6 - 4 = 2 \][/tex]

Solve for x
X^2+6x+9=20

Answers

Answer:

x = 1.47  or x = -7.47

Step-by-step explanation:

x²+6x+9=20

This is a quadratic equation

x²+6x+9-20=0

x²+6x-11=0

Step 1 : Write the quadratic formula

x = -b±√b²-4(a)(c)

              2a

Step 2 : Substitute values in the formula

a = 1

b = 6

c = -11

x = -6±√6²-4(1)(-11)

              2(1)

x = -6±√80

          2

x = -3 + 2√5 or x = -3 - 2√5

x = 1.47         or x = -7.47

!!

Answer:

x=1.472 or x=-7.472

Step-by-step explanation:

Lets begin by rearranging the equation into the format ax²+bx+c=0

The equation will be:

x²+6x+9-20=0

x²+6x-11=0

We shall use the quadratic formula to solve the equation.

x=[-b±√(b²-4ac)]/2a

=[-6±√(6²-4×1×-11)]/2

=[-6±√80]/2

=[-6±8.944]2

x= Either (-6+8.944)/2 or x= (-6-8.944)/2

Solving for x in each case gives:

x=1.472 or x=-7.472

Melissa's Heart Rate
Heart Rate -

Answers

Answer:

The domain is {1,2,3,4,5}

The range is {150,135,120,105,90}

Step-by-step explanation:

Domain is the set of x-values (x axis) and Range is the set of y-values (y axis).

Now if you look at the relation (points given), you can see the 5 points corresponds to 1,2,3,4, adn 5 in the x axis (minutes). So this is the domain - 1,2,3,4,5.

If we look at the y-axis (Heart Rate) , the values corresponding to 1,2,3,4,and 5 are 150, 135, 120, 105, and 90. These are the range.

Hence the last choice is the correct answer.

Answer: Domain = {1,2,3,4,5}

Range = {150,135, 120,105, 90}

Step-by-step explanation:

We know that,

Domain : Set of all input values .

Range : Set of output values.

In a graph, x values are the input values and y values are output values.

Given : The graph shows Melissa's heart rate in beats per minute be) during the first few minutes other cool down after  jogging .

In the graph, number of minutes are shown by x-values and heart rate are shown by y-values.

Thus from graph, Domain = {1,2,3,4,5}

Range = {150,135, 120,105, 90}

A farmer feeds his cows 200 pounds of feed each day and has 700 pounds of feed in his barn. Another farmer feeds his cows 350 lbs of feed each day and has 1000 lbs of feed in his barn. In how many days will the two farmers have the same amount of feed left?

Answers

Answer:

The farmers will have the same amount of feed (300 lbs) in 3 days

Step-by-step explanation:

Final answer:

After dividing the total amounts of feed by the daily feed amounts, it’s found that the two farmers will have the same amount of feed left after approximately 3.5 days.

Explanation:

To solve this problem, you need to find out how many days it takes for both farmers to run out of feed. For the first farmer, divide the total amount of feed (700 pounds) by the amount he uses each day (200 pounds). This comes to 3.5 days. For the second farmer, divide his total feed (1000 pounds) by the amount he uses each day (350 pounds), which comes to approximately 2.857 days.

Since we want to know when they will have the same amount of feed left, we look for the higher number, because the first farmer will still have feed left when the second farmer runs out. Therefore, the two farmers will have the same amount of feed left after around 3.5 days.

What is an equation of a line?

The equation of a line is given by:

y = mx + c

where m is the slope of the line and c is the y-intercept.

Example:

The slope of the line y = 2x + 3 is 2.

The slope of a line that passes through (1, 2) and (2, 3) is 1.

We have,

The equation of a line y + 1 = 3 (x - 4)

y + 1 = 3 (x - 4)

Subtract 1 on both sides.

y = 3(x - 4) - 1

y = 3x - 12 -1

y = 3x - 13

This is in the form of y = mx + c

Answers

Answer:

[tex]\log_{144}(12)=\frac{1}{2}[/tex]

Step-by-step explanation:

First step identify the base.  The base is 144.

The exponent is the logarithm.

The number not mentioned is the one that goes inside.

In other words [tex]a^x=b[/tex] is equivalent to [tex]log_a(b)=x[/tex]

There are some restrictions on what a and b can be.

You read  [tex]log_a(b)=x[/tex] as log base a of b equals x

x is the exponent

a is the base

So we have log base 144 of 12 equals 1/2

Step-by-step explanation:

We have 2 points, we can find the slope

m = (y2-y1)/(x2-x1)

   = (2-4)/(1--1)

   (2-4)/(1+1)

     -2/2

   =-1

The slope is -1

Then we can use point slope form to find an equation

y-y1 =m(x-x1)

y-4 = -1(x--1)

y-4 =-1(x+1)  point slope form

Using the other point

y-2 = -1(x-1)

Distribute the -1

y-2 = -1x +1

Add 2 to each side

y-2+2 = -x+1+2

y = -x +3  slope intercept form

The time it takes to read a book depends on the number of pages in the book

The situation "The time it takes to read a book depends on the number of pages in the book" in function notation is: A. Time(pages).

In Mathematics, a function is typically used in mathematics for uniquely mapping an input variable (domain or independent value) to an output variable (range or dependent value).

This ultimately implies that, an independent value represents the value on the x-axis of a cartesian coordinate while a dependent value represents the value on the y-axis of a cartesian coordinate.

In this context, we can logically deduce that time is a function of the number of pages, so it should be written in function notation as follows:

Which three pairs of measurements are possible side length for the triangle?

Answers

Answer:

A, B, E, F

Step-by-step explanation:

In a 30-60-90 triangle, the hypotenuse is twice the length of the short leg.

That makes choice E possible.

In a 30-60-90 triangle, the long leg is sqrt(3) times the length of the short leg.

That makes choices A, B, and F possible.

Answer:

First option.

Option 5.

Option 6.

Step-by-step explanation:

The formula for a 30-60-90 triangle is this:

1) Side opposite to 30 will be value [tex]a[/tex].

2) Side opposite to 60 will be value [tex]a\sqrt{3}[/tex].

3) Hypotenuse will be [tex]2a[/tex].

So let's look and see:

First option: [tex]AB=4[/tex] and [tex]BC=4\sqrt{3}[/tex]

AB is opposite of the angle with 30 degree measurement.

BC is opposite of the angle with 60 degree measurement.

So [tex]a=4[/tex] here.

So the side opposite of 60 using the formula should be [tex]4 \sqrt{3}[/tex] which it is here.

So first option looks good.

Second option: [tex]BC=2\sqrt{3}[/tex] and [tex]AC=2[/tex].

We aren't given the side opposite to 30.

AC is the hypotenuse so 2a=2 which means the side opposite to 30 is a=2/2=1.

This means using the formula that the side opposite to 60 will be [tex]1\sqrt{3}=\sqrt{3}[/tex] but we don't have that.

So not option 2.

Third option: [tex]AB=3[/tex] and [tex]AC=3\sqrt{3}[/tex]

AB is the side opposite of 30, so we have [tex]a=3[/tex]

AC is the hypotenuse so that side should be [tex]2a=6[/tex] and it isn't.

Option 3 is not working.

Fourth option: [tex]BC=10[/tex] and [tex]AC=4\sqrt{3}[/tex]

So we have that [tex]2a=4\sqrt{3}[/tex] which means [tex]a=2\sqrt{3}[/tex] and so [tex]a\sqrt{3}=2\sqrt{3}\sqrt{3}=2(3)=6[/tex] but that is a contradiction because we have this value should be 10.

Not option 4.

Option 5: [tex]AB=7[/tex] and [tex]AC=14[/tex]

So we have [tex]a=7[/tex] and [tex]2a=14[/tex] so this looks good.

Option 6: [tex]AB=11[/tex] and [tex]BC=11\sqrt{3}[/tex]

Answer:

Step-by-step explanation:

100 cm = 1 meter

200 cm = 2 meters

100 cm = 1 meter

150 cm = 150 / 100 = 1.5 meters.

1 meter = 100 cm

6.5 meters = 6.5 * 100 = 6500 cm

1 km = 1000 meters.

5 km = 5 * 1000 meters = 5000 meters.

1 meter = 100 cm

1.68 m = 100 * 1.68  

1.68 m = 168 cm

1 km = 1000 meters.

8.25 km = 8.25 * 1000 m = 8250 meters.

Add the following lengths: 4'9" + 7"

Answers

Answer:

5'4"

Step-by-step explanation:

In terms of height, the apostrophe ( ' ) stands for feet and the quotation mark ( " ) stands for inches.

Your first term includes 4 feet and 9 inches. There are 12 inches in a foot, so we can simplify this as being 57 (48+9) inches.

Your second term includes 7 inches.

Add your two terms (57 and 7) together, and you have 64 inches.

Again, there are 12 inches in a foot, so to convert 64 inches to feet, count how many times you can put 12 into 64 without surpassing 64.

12 / 24 / 36 / 48 / 60

This will result in 5 times, so you have 5 feet and 4 inches left over.
