Answer:
40 or 16+6+6+6+6
Step-by-step explanation:
To find the surface area of a 3d figure, we can imagine all of its faces laid down on a flat plane. In this case, we would have a square, and four congruent triangles. Now all we have to do is find the areas of each shape and add them up.
4 is the base of the pyramid, so it's also the square's side length. Since a square has four equal sides, our square's length and width are both 4.
4*4 = 16
For every triangle we have, the base is 4 and the height is 3. The area of a triangle can be found using the formula A=(bh)/2. We plug in the values:
A = (4*3)/2
A = (12)/2
A = 6
Since we have 4 triangles, the surface area is:
16+6+6+6+6 = 40
Answer:
If you mean factoring then 2(8-t)
Other than factoring I can't think of what you could mean by 16-2t

Step-by-step explanation:
<u>Possible number of pairs of given cards:</u>
<u>Number of sums with odd score, two odd numbers added to an even number from each box:</u>
- 2*1 + 1*2 = 4 (pairs of 3 and 5 with 2 or pairs of 9 and 3 with 4)
<u>Required probability:</u>
Answer: we wont be able to answer if there is no fill out box
Step-by-step explanation:
B = 2h
Area = 121
1/2 × b × h = 121
1/2 × 2h × h = 121
h × h = 121
h^2 = 121
h = square root of 121
h = 11
The height is 11 kilometers
