Answer:
$2.90
Step-by-step explanation:
The quantity of the 1st type of candy be x lb and that of the second type − y lb with the price of $ p/lb.
Then, x=5y/12 or y=2.4x.
The "total price" equation will be: 4.6x + 2.4xp = 3.4(x+2.4x).
Solving for p, we get p = $2.90.
Given:
The scale factor is 1:12.
Dimension of model = 32 cm
To find:
The actual dimension in m.
Solution:
Let x be the actual dimension.
The scale factor is 1:12 and the dimension of model is 32 cm.
On cross multiplication, we get
![[\because 1\ m=100\ cm]](https://tex.z-dn.net/?f=%5B%5Cbecause%201%5C%20m%3D100%5C%20cm%5D)
Therefore, the actual dimension is 3.84 m.
The answer would be 14/5.
First of all, get the denominators to be the same. The LCM is 5
