Answer:
2500
Step-by-step explanation:
it is a geometric progression
r=5
X - rows of corn,
y - rows of lettuce:
x = 2.5 y
x + y = 455
------------------
2.5 y + y = 455
3.5 y = 455
y = 455 : 3.5
y = 130
x = 2.5 * 130 = 325
Answer: The farmer plans to plant 325 rows of corn and 130 rows of lettuce.
Step-by-step explanation:
Since, The formula of Pythagoras is A² + B² + C²
(therefore)* let A be 8 mm
B be 6 mm
Therefore, 8² + 6² = 64 + 36
= 100
= 10( after squaring it )
Hope it helps,if it is correct like and mark me.
Answer:
48 cm²
Step-by-step explanation:
The copper part is two equal triangles, find a triangle's area by counting squares and multiply by two.
Total copper=(Triangle area)(2)
=b(h)(½)(2)
=b(h)
=(6)(8)
=48 cm²
