The answer is 6. first you would add up the amount of points you have. 2+3+6+6+7+8+8+8= 48. then you would count the amount of dots which is 8. last you would divide 48 by 8 which would give u 6

Answer:

5

Step-by-step explanation:

Hello There!

The mean is pretty much the average

So to find the mean we first add up all of the values

2+3+6+6+7+8+8=40

Then we count the amount of points

There are 8 points

our final step is to divide the total value by the total number of points

40/8=5

so the mean (average) would be 5

Tessa bought stock in a restaurant for $246.00 Her stock is now worth $297 66 What is the percentage increase of the value of Te

Ira Lisetskai [31]

The percentage increase of the value of Tessa's stock is 21%.

<h3>Percentage increase</h3>

Using this formula

Percentage increase=Current stock worth-Old stock worth/Old stock worth

Where:

Current stock worth=$297.66

Old stock worth=$246.00

Let plug in the formula

Percentage increase=$297.66 - $246.00 / 246.00 × 100

Percentage increase=$51.66/ 246.00 × 100

Percentage increase=21%

Inconclusion the percentage increase of the value of Tessa's stock is 21%.

the proper angle for a ladder is about 75 degrees. from the ground. suppose you have a 9 foot ladder. how far from the house sho

icang [17]

ANSWER:

2.33 foot

STEP-BY-STEP EXPLANATION:

We can calculate the distance from the staircase to the wall, by means of the trigonometric cosine ratio, which is the following:

$\begin{gathered} \cos \theta=\frac{\text{ adjacent}}{\text{ hypotenuse}} \\ \theta=75\text{\degree} \\ \text{ hypotenuse = 9 foot} \\ \text{adjacent = x} \end{gathered}$

Replacing and solving for x:

$\begin{gathered} \cos 75=\frac{x}{9} \\ x=9\cdot\cos 75 \\ x=2.33 \end{gathered}$

The distance would be 2.33 foot

Part B if the height of each prism is 10 Cm what is the surface area prism

Evgen [1.6K]

Answer:

Prism A:

$Area = 288cm^2$

Prism B:

$Area =250cm^2$

Step-by-step explanation:

Given

See attachment for prisms

$Height(h) = 10cm$

Required

Determine the surface area of both prisms

Prism A is triangular and as such, the surface area is:

$Area = 2 * A_b + (a + b + c) * h$

Where

$A_b = \sqrt{s * (s - a) * (s -b) * (s - c)}$

and

$s = \frac{a + b + c}{2}$

Such that a, b and c are the lengths of the triangular sides of the prism.

From the attachment;

$a = 8; b =6; c =10$

So, we have:

$s = \frac{a + b + c}{2}$

$s = \frac{8 + 6 + 10}{2}$

$s = \frac{24}{2}$

$s = 12$

Also:

$A_b = \sqrt{s * (s - a) * (s -b) * (s - c)}$

$A_b = \sqrt{12 * (12 - 8) * (12 - 6) * (12 - 10)}$

$A_b = \sqrt{576}$

$A_b = 24$

So:

$Area = 2 * A_b + (a + b + c) * h$

$Area = 2 * 24 + (8 + 6 + 10) * 10$

$Area = 288cm^2$

Prism B is a rectangular prism. So, the area is calculated as:

$Area = 2 * (ab + bh + ah)$

From the attachment

$a = b = 5$

$h =10$

So:

$Area =2 * (5 * 5 + 5 * 10 + 5 * 10)$

$Area =250cm^2$
