Answer:
Step-by-step explanation:
We have three similar triangles:
therefore the sides are in proportion:
We have AD = a, CD = 16 and BD = 4. Substitute:
<em>cross multiply</em>
and other proportion:
We have AB = b, BC = 16 + 4 = 20 and BD = 4. Substitute:
<em>cross multiply</em>
Answer:
try option D that should be correct
Step-by-step explanation:
Answer:
7 clusters
Step-by-step explanation:
Leaves in clusters of 3
One plant has 21 leaves
Divide 21 by 3
7 clusters of 3 leaves per cluster
To check, multiply 7 * 3, you get 21, answer is correct
Answer:
p=0.125
Step-by-step explanation:
2p+6p=1
Add like terms
8p=1
Divide both sides by 8 to get p by itself
8p/8=1/8
p=0.125
The volume of the triangular prism is:
V = (1/2) * (b) * (h) * (H)
Where,
b: base of the triangle
h: triangle height
H: prism height
Substituting:
V = (1/2) * (9) * (12) * (19)
V = 1026 cm ^ 3
The volume of the cylinder is:
V = (pi) * (r ^ 2) * (h)
Where,
r: radio
h: height
Substituting:
V = (3.14) * ((14/2) ^ 2) * (11)
V = 1692.46 yd^3
