Answer:

1 14/15

Step-by-step explanation:

Change 3 2/3 into an improper fraction, which is 11/3. When multiplying fractions, you can multiply straight across, so 11*4= 44 and 3*5 equals 15. 44/15 as a mixed fraction is 1 14/15

Using a dot plot, it is found that the number of dots of each point are given as follows:

The dot plot shows the number of times each measure appears in the data-set.

In this problem, one measure has a value of 1/8, hence:

The value [tex]\frac{1}{8}[/tex] will have one dot above it.

Two measures have a value of 1/4, hence:

The value [tex]\frac{1}{4}[/tex] will have two dots above it.

Three measures have a value of 3/8, hence:

The value [tex]\frac{3}{8}[/tex] will have three dots above it.

Five measures have a value of 1/2, hence:

The value [tex]\frac{1}{2}[/tex] will have five dots above it.

Two measures have a value of 5/8, hence:

The value [tex]\frac{5}{8}[/tex] will have two dots above it.

Answer:

The item has a 9% sales tax.

Step-by-step explanation:

Given the following question:

We are given an item that costs 490 dollars before tax, the sales tax of the item is $44.10, which means the item will cost $534.10 in total. Assuming what you are asking is to find the percentage of the sales tax we will use the formula to calculate percentages, and then add that answer to our before cost to confirm our answer.

Formula to calculate percentages:

[tex]\frac{p\times n}{100}[/tex]
[tex]p=9[/tex]
[tex]\frac{9\times490}{100}[/tex]
[tex]9\times490=4410[/tex]
[tex]4410\div100=44.1=44.10[/tex]
[tex]490+44.10=534.10[/tex]
[tex]=534.10[/tex]

Our sales tax percentage is 9%.

Hope this helps.

Answer:

  C.  (1, -1/2)

Step-by-step explanation:

The midpoint of a line segment has coordinates that are the average of the end point coordinates.

__

  M = (A +B)/2 . . . . . . midpoint of segment between A(1, 4) and B(1, -5)

  M = ((1, 4) +(1, -5))/2 = (1 +1, 4 -5)/2 = (2, -1)/2

  M = (1, -1/2)

The midpoint of the vertical line segment is (1, -1/2).

Additional comment

The midpoint will always be on the line segment. Since this line segment is vertical with x = 1, the x-coordinate of the midpoint must be 1.

Answer:

28

Step-by-step explanation:

Circumference = 2*pi*r

r = 1/2*diameter = 4.5

pi = 3.14

Circumference = 2*(3.14)*(4.5) = 28.26 = 28

The slope and the y intercept of the line on the graph is -1/4 and 1.

A straight line function is what can be written in the form of

y =mx +c

where m is the slope and c is the intercept on y axis.

The intercept on the y axis , c = 1

at x = 4 , y=0

and at x = 0, y =1

The slope can be calculated as

y = mx+1

0 = 4m +1

m = -1/4

Therefore the slope and the y intercept of the line on the graph is -1/4 and 1.

Answer:

B) x² - 8x + 12

E) (x -4)² - 4

F) (x - 2)(x - 6)

Explanation:

As the graph opens upwards. The value of x² will be positive.

The x intercepts are (2, 0), (6, 0) determining (x -2)(x-6)

The (x - 4)² - 4 determines the vertex of x = 4, y = -4

When simplified:

⇒ (x -2)(x-6)

⇒ x² - 2x -6x + 12

⇒ x² - 8x + 12

The number that will produce a rational number when multiplied by 1/5 is A. 10.

A rational number is one that can be written in the form of a fraction where the denominator isn't 0. This number is an integer and does not repeat infinitely.

When 1/5 is multiplied by 10 we get:

= 1/5 x 10

= 2

2 is a rational number so option A is correct.

Let's take this problem step-by-step:

Let's first set up some variables:

Let's examine the information given:

          ⇒ average child is 75 pounds

          ⇒ average adult is 150 pounds

                 ⇒ therefore: [tex]75c + 150a\leq 1500[/tex]

          ⇒ therefore: [tex]c + a \leq 14[/tex]

Let's graph the equations:

 [tex]75c+150a\leq 1500\\c+a\leq 14[/tex]

    ⇒ look at the image attached

The point at which the two graphs intersect:

  ⇒ is the solution that represents the amount of children and adults and

      their combine weight

With the horizontal axis being the # of children and vertical axis being the # of adults:

Answer:

79% of females are attending the class field trip

Step-by-step explanation:

Question Breakdown:

- Survey 271 students

- 121 males respond, 92 attending field trip

- 31 females not attending field trip

What percent of females are attending the class field trip?​

The two-way table or the class whether they are attending the field trip or not is attached below,

The table tells us

• Males who are not attending : 121 - 192 = 29

• Total females who responded : 271 - 121 = 150

• Females who are attending : 250 - 31 = 119

• Total students who are attending : 91 + 119 = 211

• Total students who are not attending : 29 +31 = 60

There are a total of 150 female students and 119 of them are attending the field trip

[tex]\frac{119}{150} = 0.79 x 100 = 79%[/tex]

⇒x=-0.5x=−0.5

Now, substituting the value of x=-0.5 in equation (2), we get

y=0.25-0.5+2y=0.25−0.5+2

⇒y=1.7y=1.7

Thus, the values of x and y are -0.5 and 1.7.

Therefore, the approximate solution of the given system of the equation is (-0.5, 1.7).

The system of exponential functions that can be used to determine the time for the profits to be the same is given by:

[tex]3000(0.985)^x = 1500(1.012)^x[/tex]

An exponential function is modeled by:

[tex]A(t) = A(0)(1 \pm r)^t[/tex]

In which:

For the first restaurant, we have that the parameters are given as follows:

A(0) = 3000, r = -0.015.

Hence the profit after x weeks is given by:

[tex]y_1(x) = 3000(0.985)^x[/tex]

For the second restaurant, we have that:
A(0) = 1500, r = 0.012.

Hence:

[tex]y_2(x) = 1500(1.012)^x[/tex]

Then they will be equal when:

[tex]y_1(x) = y_2(x)[/tex]

[tex]3000(0.985)^x = 1500(1.012)^x[/tex]
