Answer:
11.15862 fluid ounces
Step-by-step explanation:
first change 5 milliliters to fluid ounces which is 0.16907 fluid ounces times 6 because every four hours a day. Then 0.16907 times 6 equals 1.01442. So you do 1.01442 times 11 for the 11 days which gives u the answer "11.15862".
70 flowers were planted in all.
Step-by-step explanation:
Let,
Tulips = t
Daises = d
Lilies = l
Total tulips planted = 42
She planted 2 times as many tulips as daises.
t=2d
Putting t=42
Dividing both sides by 2
And 3 times as many daisies as lilies.
d=3l
Putting d=21
Dividing both sides by 3
Total flowers planted = Tulips + Daisies + Lilies
Total flowers planted = 42 + 21 + 7 = 70
70 flowers were planted in all.

Answer:
the dimensions of the most economical shed are height = 10 ft and side 5 ft
Step-by-step explanation:
Given data
volume = 250 cubic feet
base costs = $4 per square foot
material for the roof costs = $6 per square foot
material for the sides costs = $2.50 per square foot
to find out
the dimensions of the most economical shed
solution
let us consider length of side x and height is h
so we can say x²h = 250
and h = 250 / x²
now cost of material = cost of base + cost top + cost 4 side
cost = x²(4) + x²(6) + 4xh (2.5)
cost = 10 x² + 10xh
put here h = 250 / x²
cost = 10 x² + 10x (250/ x² )
cost = 10 x² + (2500/ x )
differentiate and we get
c' = 20 x - 2500 / x²
put c' = 0 solve x
20 x - 2500 / x² = 0
x = 5
so we say one side is 5 ft base
and height is h = 250 / x²
h = 250 / 5²
height = 10 ft
Answer:
105km
Step-by-step explanation:
2.5/15=17.5/x (set up as a proportion)
2.5x=262.5 (cross multiply)
x=105 (Divide)
