10. On one night, a group of 9 rats carried away 45 kg of food. What is the reduced ratio of rats to food weight

GenaCL600 [577]

Answer:

Number of rats : Food weight = 1 : 5

Step-by-step explanation:

Number of rats in the group = 9

Weight of food carried away by them = 45 kg

Ratio of the number of rats and food weight = $\frac{\text{Number of rats}}{\text{Weight of food carried by the rats}}$

= $\frac{9}{45}$

= $\frac{1\times 9}{5\times 9}$

= $\frac{1}{5}$

Therefore, Number of rats : Food weight = 1 : 5

X = 1/2at^2 Solve for t. 1. 2. 3. 4.

mash [69]

Answer:

sqrt(2x/a) = t

Step-by-step explanation:

X = 1/2at^2

Multiply by 2 on each side

2x = 2*1/2at^2

2x =at^2

Divide by a

2x/a=a/a t^2

2x/a =t^2

Take the square root of each side

sqrt(2x/a) =sqrt(t^2)

sqrt(2x/a) = t
