Step-by-step explanation:

To find the surface area of a triangular prism:

Find the base area and the remaining 3 rectangles and add them all together.

1.5*2=3 (base of the shape)

2*13=26

1.5*13=19.6

2.5*13=32.5

3+26+19.6+32.5=81.1

The difference in the pay rate of Phoebe in 5 years will be $11850

Your information is incomplete. Therefore, an overview will be given. Let's assume that the pay rate is $20000. When there is a 5% increase, the new pay rate will be:

= $20000 + (5% × $20000)

= $20000 + $1000

= $21000

When there is $0.75 increase per hour, the new pay rate on 5 years will be:

= (0.75 × 43800)

= $32850

The difference will be:

= $32850 - $21000

= $11850

Answer:

90.93%

Step-by-step explanation:

It is clear that the table is a linear function. That is, every hour, the amount of corn increases by the same amount. You can find the slope of the linear function by using the slope formula:

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

In your case, the number comes out to be 825. So the number of corn will be 825*10 = 8250 cu ft.

Now, we know that the volume is area times height. So if the area is pi * r * r, then the volume of the shape is 2888*pi.

Therefore, the answer is 8250/2888*pi or 90.93%.

Answer:

Step-by-step explanation:

a) 147

b)147

c) 152

d)65

Answer:

a) mean = 147

b) median = 147

c) mode = 152

d) range = 65

Step-by-step explanation:

firsly let’s arrange the numbers of the set in ascending order:

117 , 119 , 138 , 142 , 152 , 152 , 174 , 182

a)

[tex]Mean = \frac{117+119+138+142+152+152+174+182}{8} =\frac{1176}{8} =147[/tex]

b) the median is the average of the two middle numbers :

[tex]117,119,138, \frac{142,152}{} , 152,174,182[/tex]

[tex]median=\frac{142+152}{2}= 147[/tex]

c) the modal height is 152 because 152 is the value that appears most frequently (2 times) in our set

d) the range of a set is the difference between the highest and lowest numbers :

Then

the range = 182-117 = 65

Answer:

Let's find the number of arrangements with mother and father together, say N & then subtract it from total number of arrangements.

Total arrangements = 6! = 720.

Now, as mother & father are together, let's treat mother and father as a single person. Now, there're 5 persons.

Number of arrangements in this way = 5! = 120.

But mother and father can change their places in 2! = 2 ways.

N = 120 × 2 = 240.

Ans. = 720-240 = 480.

Applying the law of cosine, b² = a² + c² - 2ac(cos B), the length of AC of the marsh, to one decimal place, is: 522.1 meters

The Law of Cosine is given as, b² = a² + c² - 2ac(cos B).

From the diagram given, we have the following:

Plug in the values into the law of cosine formula:

b² = 220² + 420² - 2(220)(420)(cos 105)

b² = 272,629.8

b = √272,629.8

The value of y in point C is 0. So, C is located at (2, 0) in the Cartesian plane.

Given that a parallelogram ABCD is shown in the Cartesian plane.

The points are:

A = (-1, 2)

B = (2, 3)

C = (2, y)

D = (-1, -1)

We are asked to find the value of y in the point C.

To find the value of y in point C, we can use the fact that the slope of line AB is equal to the slope of line DC, and the slope of line BC is equal to the slope of line DA.

The slope of a line passing through two points (x₁, y₁) and (x₂, y₂) is given by:

slope = (y₂ - y₁) / (x₂ - x₁)

Let's calculate the slope of line AB and DC:

Slope of AB = (3 - 2) / (2 - (-1))

= 1 / 3

∴ Slope of DC = 1 / 3.

So,

1/3 = (y+1) / (2+1)

1/3 = (y + 1) / 3

y + 1 = 1

y = 0

Hence, we get the value of y in point C is 0.

[Note:- you can simply look at the graph and can determine the location of the point C]
