Answer:
The total surface area of triangular pyramid is 172 cm squared
Step-by-step explanation:
Triangular pyramid:
- Number of faces 4.
- Number of vertices of a triangular pyramid is 6.
- The volume is
. A= area of the pyramid's base and H= height of the pyramid.
- The surface area of triangular pyramid B+L. B= area of base, L= area of lateral surface.
Given that, the area of the base is 43 cm squared. Lateral faces with bases of 10 cm and heights 8.6 cm.
The 3 sides of the triangular pyramid is triangle in shape.
The area of triangle is 
.
The lateral surface area of the triangular pyramid is
cm squared
=129 cm squared
The total surface area of triangular pyramid is
=Area of the base + lateral surface area
=(43+129) cm squared
=172 cm squared
Find the mean, median and mode of these sets of data: a. 14,12,24,36,23 c. 2,3,4,5,30 b. 114,112,124,136,123 d. x, 2x,3x,4x,5x

Answer:
first u need to rearrange the three sets of data in ascending order
i'll just do a set here as an example
a: 12, 14, 23, 24, 36
Mean: (12+14+23+24+36)/5 = 21.8
Median: 23
Mode: 0 (as none of the datum is repetitive)
Answer:
22221
Step-by-step explanation:
I set up the problem like this
823
x27
Then I multiplied 7 by 3 and carried over the one and then multiplied 7 by 2 and added one and carried the one over... I then multiplied 7 by 8 and added the one!
Then I put a zero where the 7 I first multiplied would be... I then multiplied 2 by 3 and then multiplied 2 by 2 and finally multiplied 2 by 8!
I then added up the two values! (Sorry this probably sounds confusing!)
Answer:
The correct answer is (-2,-5).
Step-by-step explanation:
Ordered pairs in the first quadrant: x>0 and y>0.
Ordered pairs in the second quadrant: x<0 and y>0.
Ordered pairs in the third quadrant: x<0 and y<0.
Ordered pairs in the fourth quadrant: x>0 and y<0.
If City Park is shown on (-3,-4), then in the third quadrant.
Jade's house is in the same quadrant as the city park. Which of the following could be the coordinates of Jade's house?
(2, 5)
(−2, 5)
(2, −5)
(−2, −5)
Answer:
<h2>Volume = 1659.84</h2><h2>Surface area = 1205.36</h2>
Step-by-step explanation:
Volume for triangular prism = 1/2 * b * l * h
we are given the length and the height but not the base.
since it is a right triangle we can use the Pythagorean theorem a^2 + b^2 = c^2
13.3^2 + b^2 = 20.5^2
176.89 + b^2 = 420.25
b^2 = 243.36
b = 
= 15.6
1/2 (15.6)(13.3)(16) = 1659.84
Front: 15.6 x 13.3 = 207.48
Back: 15.6 x 13.3 = 207.48
Left: 15.6 x 16 = 249.6
Right: 13.3 x 16 = 212.8
Bottom: 20.5 x 16 = 328
207.48 + 207.48 + 249.6 + 212.8 + 328 = 1205.36
