The ratio of the height to shadow length is a constant.
.. (5 ft)/(132 ft) = (tree height)/(144 ft)
.. (tree height) = (144 ft)*(5/132) = 5 5/11 ft
Answer:
Step-by-step explanation:
a) (2,350),(5,530)
b) (530-350)/(5-2)=60
c) y=60x+b, using point (2,350)
350=60(2)+b
b=230
w=60t+230
c) w(7)=60(7)+230
w(7)=$650
Answer:
The better buy is to buy 10 kilograms of potatoes at $ 3.92, since each kilogram costs $ 0.392.
Step-by-step explanation:
To find the cost per unit in each case and then state which is the better buy, the following calculations must be performed:
6kg of potatoes for $ 2.45:
2.45 / 6 = 0.408
15 kg of potatoes for $ 5.9:
5.90 / 15 = 0.393
10 kg of potatoes for $ 3.92:
3.92 / 10 = 0.392
Thus, the better buy is to buy 10 kilograms of potatoes at $ 3.92, since each kilogram costs $ 0.392.
