The angles are equal (alternate angles in parallel lines)
X + 86 = 80
X = 80 - 86 = -6
Furniture costs 3% more than last year.
So last year furniture cost 97% of the current price.
Price for tables last years was = 97/100 × $2950 = $2861.5
Which is $2862 to nearest dollar.
Price for chairs last year = 97/100 × $3850 = $3734.5
Which is $3735 to nearest dollar.
DH/dt=k(68-H)
1/(68-H)dH=kt assuming k is a constant
ln|68-H|=kt+C (*)
we have all H satisfying (*)
Answer:
a+b must be greater than 8
Step-by-step explanation:
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.
