Answer:
144
Step-by-step explanation:
On this shape we are going to splt up the 4 triangles for the square to make it simple.
So, firstly, plug is the h an w of one of the triangles into the formula for the area of a triangle which is hxw/2
H=9
W=6
9x6/2=27
Then multiply the area of the triangle, 27, to get the total area of all 4 triangles (since they all have the same measurements)
27x4=108
108 is the area of all 4 triangles
Next, just put the l and w into the equation for the area of a square which is lxw
L=6
W=6
6x6=36
36 is the area of the square
Lastly, just add the areas of the triangles and the square together
108+36=144
144 is the total area/surface area, of the pyramid
Hi there! To do this, we can divide both fractions. We have to convert the fractions into improper fractions. 15 3/4 (63/4) and 2 1/4 (9/4). To divide fractions, keep the first fraction the same, change division into multiplication, and flip the second fraction over. 63/4 * 4/9 is 252/36 or 7 when simplified. The average rate of speed was 7 miles per hour.
Answer:
4:6 or 2:3
Step-by-step explanation:
Since the ratio of mass of oxygen to carbon is 4:3, when there are two carbons the ratio will be 4:3*2=4:6=2:3. Hope this helps!
1 pie is cut into eighths or 1/8 a slice. 3 are taken out.
