To find the area of the wrapping paper you have to find the serface area of the ball 
you have the volume so you have to find the raduis using the formula
r=3(v/4pi)^1/3
r=3(288pi/4pi)^1/3
r=3(72)^1/3
r=216^1/3
r=6
then the surface area of the sphere
SA=4pi x r^2
SA=4pi x 6^2
SA=4pi x 36
SA=144pi

Triangular Prism- SA= 1/2bh
                          = 1/2 × 7 × 11
                          = 38 1/2 × 4 = 154
                             7 × 7 = 49
                          = 154 + 49
                          = 204in³

Rectangular Prism- SA= 2lw + 2lh + 2wh
                             = 2 × 11 × 7 + 2 × 11 × 7 + 2 × 7 × 7
                             = 154 + 154 + 98
                             = 406in³

Therefore, the rectangular prism has the larger surface area.

From point A and B on level ground, the angles of
gladu [14]

Answer:

Step-by-step explanation:

Call T the top

call G the bottom

T G B is a right triangle

37 at B, 90 at G, thus 53 at BTG

TGA is a right triangle

25 at A, 90 at G, thus 65 at ATG

thus 122 at ABT

law of sines:

sin 25 / BT = sin 12/ 57

so BT = 156 meters (first answer)

now angle ABT = 180 - 12 - 25

= 143

so

sin 143 /AT = sin12/57

AT = 164 meters, second answer

What is the equation of the line in point-slope form?
evablogger [386]

Answer:

y +500 = -\frac{1}{5}(x - 100)

Step-by-step explanation:

Given

The attached graph

Required

Determine the equation in point slope form

From the graph, we have the following points;

(x_1,y_1) = (-400,-400)

(x_2,y_2) = (100,-500)

First, we calculate the slope (m):

m = \frac{y_2 - y_1}{x_2 - x_1}

m = \frac{-500 - (-400)}{100- (-400)}

m = \frac{-500 +400}{100+400}

m = \frac{-100}{500}

m = -\frac{1}{5}

The equation is then calculated using:

y - y_2 = m(x - x_2)

Substitute x and y values

y - (-500) = -\frac{1}{5}(x - (100))

y +500 = -\frac{1}{5}(x - 100)

Using the table for many repetitions of the experiment of tossing a coin 10 times, what is the mean number of heads in 50 repeti
PtichkaEL [24]
When there are 1000 repetitions, the mean will be 5.002.

The charts that you have list the number of total heads when you flip the coin 10 times in each trial.

Multiply the total of each by the number number of heads for that category and divide by 1000.

1 x 0
8 x 1
43 x 2
117 x 3
2017 x 4
248 x 5
203 x 6
121 x 7
45 x 8
6 x 9
1 x 10

If you add up those products and divide by 1000, you have 5.002.

Using the law of large numbers, the experiment with 1000 rolls will be the closest to the theoretical amount.

Rewrite the following equation in slope-intercept form. 17x + 15y = 5 Write your answer using integers, proper fractions, and im
omeli [17]
Answer:
y = \frac{-17}{15} x + \frac{1}{3}

Explanation:
The slope-intercept form of the equation has the following formula:
y = mx + c
where:
m is the slope
c is the y-intercept

The given is:
17x + 15y = 5

To put it in the slope-intercept formula, we should isolate the y as follows:
17x + 15y = 5
15y = -17x + 5
y = (-17/15) x + (5/15)
y = \frac{-17}{15} x + \frac{1}{3}
where:
m is the slope = -17/15
c is the y-intercept = 1/3

Hope this helps :)
