Solve your word problem using a model. Use complete sentences to describe your model, and interpret the quotient in the context of your word problem. If you wish, you may upload a copy of your model.

Answers

The model [tex]x = \frac{6}{3}[/tex], can be used to solve the world problem representing a scenario where John wants to share 6 apples amongst his three friends. x = 2, is the quotient which is interpreted as the number of apples each of John's friend will get.

Word problem describes real world situations which can be translated into expressions as a model.

For example, if John has 6 apples and John has three friends, how many apples would each of the friend get (x) if he is to share the 6 apples amongst the three of them?

To solve this, we can model the situation as follows:

Let x represent the number of apples each friend would get (quotient).

Thus:

[tex]x = \frac{6}{3}\\\\\mathbf{x = 2}[/tex]

The quotient (x) in this model can be interpreted as the number of apples each of John's friend will get.

Thus, the model [tex]x = \frac{6}{3}[/tex], can be used to solve the world problem representing a scenario where John wants to share 6 apples amongst his three friends. x = 2, is the quotient which is interpreted as the number of apples each of John's friend will get.

The width of a rectangular parking lot at the meadowlands is 3/8 mile. If the area is 5/8 square mile, what is the length of the parking lot

Answers

let width is x and length is y

x * y = area

=> 3/8 * y = 5/8

=> y = 5/8 ÷ 3/8

=> y = 5/8 * 8/3 = 5/3

the length of the rectangular parking lot is 5/8 mile.

78 decreased by half a number is 45 Find the number

Answers

78 - 45 = 33
Since it’s half a number you do
33 x 2 = 66
So the answer is 66

Answer:

number is 66

Step-by-step explanation:

let the number be n , then

78 - [tex]\frac{1}{2}[/tex] n = 45 ( subtract 78 from both sides )

- [tex]\frac{1}{2}[/tex] n = - 33 ( multiply both sides by - 2 to clear the fraction )

n = 66

The required number is 66

Colleen buys a robot priced at $33.If the sales tax is10%,how much tax will Colleen pay?

Answers

Answer:

$3.3 tax

Final price is 36.3

Step-by-step explanation:

Firstly, if the tax is expressed in percent, divide the tax rate by 100. You can do this by simply moving the decimal point two spaces to the left. In this example, we do 10/100 = 0.1

tax= 33 * 0.1

tax=3.3

Finally, add tax to the before tax price to get the final price including tax.

The final price including tax = 33 + 3.3 = 36.3

A coin was tossed 80 times, out of which it landed on heads 60 times. What is the relative frequency of the coin toss resulting in tails?

Answers

Answer : 25%

Step-by-step explanation : If a coin was tossed 80 times and it landed 60 times, 80 - 60 = 20 so 20/80 were tails, let's convert that into % so 20 is 1/4 of 80 so 25%.

please help, I don't know what to do​

Answers

Answer:

6%

Step-by-step explanation:

60 = 500•2•rate

Consider this function.
h(x) = (x - 2)^2+3

Which of the following domain restrictions would enable h(x) to have an inverse function?
a. x < 1
b. x >5
c. x < 3
d. x > 4

(Ps: all four answer and larger equal then or smaller equal then

Answers

Answer:

No inverse function:  (a), (b), (c)

Inverse function exists:  (d)

Step-by-step explanation:

The graph of h(x) = (x - 2)^2 + 3 is a parabola that opens upward and has vertex at (2, 3).  If the entire graph is drawn, and the horizontal line test then applied, h(x) would not have an inverse, because the horizontal line would intersect the  parabolic graph twice.

Note that if we restricted the domain to x ≥ 2, the resulting graph would pass the horizontal line test.  This would also be true for x ≥ 3, x ≥ 4, and so on.  Not so for (a) x < 1.  False for x > -5.  True for x < 3.  True for x > 4.

No inverse function:  (a), (b), (c)

Inverse function exists:  (d)

Answers

Answer:

A = (1, 10)

B = (4,10)

C = (4, 14)

D = (1, 16)

Step-by-step explanation:

Okay, so first, we move, or translate the quadrilateral PQRS down -8 spaces on the graph, turning old points:

P (1, -2) = (1, -10)     Q (4, -2) = (4, - 10)     S (1, -8) = (1, -16)     and R (4, -6) = (4, -14)

Now, we need to rotate this new box into -x, y. So our new points are:

(1, -10) = (-1, 10)     (4, -10) = (-4, 10)     (1, -16) = (-1, 16)     and (4,-14) = (-4, 14)

Now we're reflecting off the y-axis, making our x change. So for our final points:

A(1, 10)   B (4,10)    D(1, 16)    and C(4, 14)

Answer:

Q1: 0.88015 ~ 88.015%, are

Q2: 0.88176 ~ 88.176%, are not

Step-by-step explanation:

Okay so a simple way to do these probability ones is to add an extra space around each side  

                                   A        B        C        D

ACCURATE               310    262    246    144    ___

NOT ACCURATE       31       51       37       12    ___

                                  ___    ___     ___    ___   ___  

Now in these spaces add all the the rows and columns accordingly  

                                    A          B          C          D

ACCURATE               310      262      246      144       _962_

NOT ACCURATE       31         51         37         12        _131_

                                 _341_  _343_  _283_  _156_   _1093_

Now the number in the place where the additional rows meet is your total number of orders, so this is what you would use for your probability.  

So we are looking for ACCURATE / ALL which is 962  

Now do 962 divided by 1093 and your probability comes out to 0.88015, so as a percentage, would be 88.015%

With replacement, all variables become independent, however without replacing that changes the probability.

When the 2 orders are selected, the final number of probability changes - so it would take down the total each time, the find the mean or average of the probability for your answer.

So since there is no replacement for ACCURATE / ALL which is 962, the division instead would be by 1091, since we are taking 2 orders out and not putting them back, it brings down the total number by 2, which would make the probability come out to 0.88176, or 88.176%

(81)¾ - (27)⅓
\3 × 2³​

Answers

Answer:

I won't tell you the answer but if you read the solution, you would understand it.

Step-by-step explanation:

81^3/4 is basically 3 times the fourth root of 81. What number multiplies 4 times to make 81? Then multiply that by 3.

Now we have the cube root of 27. If you have a fractional exponent with no numerator, that just means square root, cube root, fourth root.

Eg. the exponent 1/4 would just mean fourth root

Eg. The exponent 1/2 would just mean square root

The cube root of 27 is 3.

The denominator is 3 times 2 to the third power.

PEMDAS

Order of Operations tells us we do exponents first so 2 to the third power is 8 and multiply by that 3.

When dividing fractions, you can multiply by the inverse of the fraction. For example, in this case, [tex]14 divided by \frac{2}{3} = \frac{14}{1}x\frac{3}{2}[/tex]. Whoever drew the calculations made the mistake of forgetting to flip the second fraction.

Answer:

A

Step-by-step explanation:

The reason that this is A is because 5$ is the initial fee and you dont pay any more than that, since 21$ is the max you can afford it is going to be less than or equal to 21. and if it is 2.75$ per stop then it is the number of stops times 2.75. A is your answer.

Three sisters have ages that are consecutive odd integers. The sum of the age of the youngest and three times the age of the oldest is five less than five times the middle sister’s age.

Answers

Answer:

youngest   17  

middle  19

oldest    21

Step-by-step explanation:

Three sisters have ages that are consecutive odd integers

youngest = x

middle = x + 2

oldest = x + 4

--------------------

The sum of the age of the youngest

x

and three times the age of the oldest

+ 3(x + 4)

is five less than five times the middle sister’s age

= 5(x + 2) - 5

-----------------------

x + 3(x + 4) = 5(x + 2) - 5

Distribute

x + 3x + 12 = 5x + 10 - 5

Combine like terms

4x + 12 = 5x - 5

Subtract 4x from both sides

12 = x - 5

Add 5 to both sides

17 = x

youngest   x = 17  

middle     x + 2 = 19

oldest     x + 4 = 21

What is the equation of a line that is perpendicular to the line y=2x+1 and passes through the point (4,6)?

Answers

Answer:

y = - [tex]\frac{1}{2}[/tex] x + 8

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = 2x + 1 ← is in slope- intercept form

with slope m = 2

Given a line with slope m then the slope of a line perpendicular to it is

[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{2}[/tex] , then

y = - [tex]\frac{1}{2}[/tex] x + c ← is the partial equation

To find c substitute (4, 6 ) into the partial equation

6 = - 2 + c ⇒ c = 6 + 2 = 8

y = - [tex]\frac{1}{2}[/tex] x + 8 ← equation of line
