The answer to this question would be length is 4 and the width is 8.
My explanation: Well, all i did was think of what two numbers go into 32 and those were the first 2 that came into my mind ;-}
Given:
Big cone : diameter = 12 cm ; height = 18 cm ; base = 14 cm
Small cone: diameter = 12 cm ; height = 6 cm ; base = 14 cm
Volume of a cone-shaped container = π r² h/3
Big cone:
V = 3.14 * (6cm)² * 18cm/3
V = 3.14 * 36cm² * 6cm
<span>V = 678.24 cm³
</span>Small cone:
V = 3.14 * (6cm)² * 6cm/3
V = 3.14 * 36cm² * 2cm
<span>V = 226.08 cm³
</span>Big cone - small cone = volume of water
678.24 cm³ - 226.08 cm³ = 452.16 cm³
Let x represent the days it will take for the stalk to be at least 300 cm tall
3x+9≥300
3x≥291
x≥97
Ok so to find best price, find cost per unit or unit rate
so what we do is
(amount of flower x batches)/x and divide out
when dividng fractions, just invert the second one and multiply, example
3/4 divided by 5/6=3/4 times 6/5=18/20 so
A.1/2 cup for 2/3, (1/2)/(2/3), 1/2 times 3/2, 3/4 cup per batch
B. 1/3 per 1/4 batch, (1/3)/(1/4), 1/3 times 4/1, 4/3 cup per batch=1 and 1/3
C. 2/3 cup for 1/2 batch, (2/3)/(1/2), 2/3 times 2/1, 4/3 cp per batch=1 and 1/3
D. 3/4 cup per 2/3 batch, (3/4)/(2/3), 3/4 times 3/2, 9/8 cup per batch=1 and 18/
lowest unit rate is 3/4 cup per batch since others are greater than 1
answer is A
32^3/5 = (2^5)^3/5 = 2^(5*3/5) = 2^3 = 8
