Answer:
74.4 m³
Step-by-step explanation:
The volume (V) of the prism is calculated as
V = area of triangular base × length
area of triangle = 0.5 × 5 × 4.8 = 12 m², thus
V = 12 × 6.2 = 74.4 m³
Answer:
38
Step-by-step explanation:
Since he wants to have equal number of rows and columns..the number of plants must be a root number. 6203 is not a root number. 6241 is the closest root number
(√6241= 79)
So he needs a minimum of 6241 plants in total for it.
6241-6203= 38
Therefore he needs 38 more plants
3x + 5y = 1 . . . . . . . . (1)
7x + 4y = -13 . . . . . . .(2)
(1) x 7: 21x + 35y = 7 . . (3)
(2) x 3: 21x + 12y = -39 .(4)
(3) - (4) = 23y = 46
y = 46/23 = 2
Answer:
21
Step-by-step explanation:
13 + 4(9-7) =
13 + 4(2) =
13 + 8 = 21
