Answer:

Step-by-step explanation:

12    Cost(1.779) = 74.11

      Cost = 74.11 / 1.779

       Cost = $41.66

Markup = 41.66(0.779) = $32.45

or

Markup = 74.11 - 41.66 = $32.45

PLZ HELP WITH NUMBER 4 AND 5

Answers

Answer:

Question 4: 70 degrees

Question 5: 150 degrees

Step-by-step explanation:

Question 4:

The shape is a polygon therefore we need to first find the sum of the angle. The formula is: (number of sides - 2) * 180

Rewrite: (5 - 2) * 180 = 540

To get the answer we add all angles together which is:

135 + 120 + 80 + 135 = 470

Minus to get the last angle:

540 - 470 = 70 degrees

So the answer is 70 degrees:

x = 70 degrees

Question 5:

Again the type of shape is an polygon so first we need to find the sum of the angle.

(6 - 2) * 180 = 720

Next add up all the angles together. The square boxes mean the angle is a right angle. So we can just add 90 degrees for every box you see.

90 + 90 + 120 + 120 = 420

Minus the answer with the sum of the total angle to get the missing value:

720 - 420 = 300 degrees

Next since there are two x, and they are at the same position they are the same value so we can just divide and get the answer.

300 / 2 = 150 degrees

Therefore the answer for both x are 150 degrees:

x = 150 degrees.

Answers

Answers:

First Blank = 54Second Blank = 162

=============================================

Explanation:

The first blank represents the distance that corresponds to t = 1 hour.

We'll replace t with 1 to get...

d = 54t

d = 54*1

d = 54

Therefore, 54 goes in the first blank. It means that Isaac traveled 54 miles after 1 hour.

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

We repeat these steps for t = 3

d = 54*t

d = 54*3

d = 162

This means he traveled 162 miles after 3 hours

So 162 goes in the second blank

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

Side note: your teacher wrote 180 but s/he should have written 108 instead because 54*2 = 108

An inverted pyramid is being filled with water at a constant rate of 70 cubic
centimeters per second. The pyramid, at the top, has the shape of a square
with sides of length 6 cm, and the height is 13 cm.
Find the rate at which the water level is rising when the water level is 3 cm.
cm/sec

Answers

Rates of change are the change of a quantity over another.

The rate of change in height of the water level is 36.51 cm per second.

Let the length of the top square be s, and the height be h.

The volume of the pyramid is:

[tex]\mathbf{V = \frac{1}{3}s^2h}[/tex]

At time t, we have:

[tex]\mathbf{V = \frac{1}{3}s(t)^2h(t)}[/tex]

The relationship between the side length and height is:

[tex]\mathbf{s : h=6 : 13}[/tex]

Express as fractions

[tex]\mathbf{\frac{s }{ h}=\frac{6 }{ 13}}[/tex]

Make s the subject

[tex]\mathbf{s=\frac{6 }{ 13}h}[/tex]

So, we have:

[tex]\mathbf{V = \frac{1}{3}s^2(t)h(t)}[/tex]

[tex]\mathbf{V = \frac{1}{3} \times (\frac{6 }{ 13}h(t))^2 \times h(t)}[/tex]

[tex]\mathbf{V = \frac{1}{3} \times \frac{36}{ 169}h^2(t) \times h(t)}[/tex]

[tex]\mathbf{V = \frac{1}{3} \times \frac{36}{ 169}h^3(t)}[/tex]

Differentiate

[tex]\mathbf{V'(t) =3 \times \frac{1}{3} \times \frac{36}{ 169}h^2(t) \times h'(t)}[/tex]

[tex]\mathbf{V'(t) =\frac{36}{ 169}h^2(t) \times h'(t)}[/tex]

Make h'(t) the subject

[tex]\mathbf{h'(t) = \frac{169 \times V'(t)}{36 \times h^2(t)}}[/tex]

The water level rises constantly at 70 cm^3/s, and the water level is 3 cm.

So, we have:

[tex]\mathbf{V'(t) = 70}[/tex]

[tex]\mathbf{h(t) = 3}[/tex]

[tex]\mathbf{h'(t) = \frac{169 \times V'(t)}{36 \times h^2(t)}}[/tex] becomes

[tex]\mathbf{h'(t) = \frac{169 \times 70}{36 \times 3^2}}[/tex]

[tex]\mathbf{h'(t) = \frac{169 \times 70}{36 \times 9}}[/tex]

[tex]\mathbf{h'(t) = 36.51}[/tex]

Hence, the rate of change in height of the water level is 36.51 cm per second.

What is the median for the data shown below?

S= [110, 105, 126, 65, 134, 102, 78, 80, 119, 67, 88]

Answers

Answer:

102

Step-by-step explanation:

The median of a data set is found by putting the data set in ascending numerical order and identifying the middle number. If there are an odd number of data values in the data set, the median is a single number. If there are an even number of data values in the data set, the median is the average of the two middle numbers. Sorting the data set for the values entered above we have:

65 , 67 , 78 , 80 , 88 , 102 , 105 , 110 ,119 , 126 , 134

Since there is an odd number of data values in this data set, there is only one middle number. With 11 data values, the middle number is the data value at position 6. Therefore, the median is 102.

Answer:

102

Step-by-step explanation:

1. The median is the quantity that's in the middle of a data set.

2. First, we have to arrange the given data set from least to greatest:

65, 67, 78, 80, 88, 102, 105, 110, 119, 126, 134

3. Now, when we try and locate the middle number, we can see that the number is 102.

Therefore, the median is 102.
