Answer:
1.2
The first step would to be to plug in your numbers for your variables, so
ab/bc= (6)(0.9)/(0.9)(5)
(6)(0.9)/(0.9)(5)
6*0.9=5.4
0.9*5=4.5
5.4/4.5=1.2
Step-by-step explanation:
Answer:
146 in
12ft 2in
Step-by-step explanation:
4ft 9 = 4*12+9=48+9=57
3ft 10 = 3*12+10=36+10=46
3ft 7 = 3*12+7=36+7=43
57+46+43=146
146/12 = 12ft remainder 2
12ft 2in
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
