Answer: 10 minutes.

Step-by-step explanation: Since the cells get double in every 5 minutes, so the number of bottles that will be filled in 5 minutes= 2. After another 5 minutes, these 2 bottles of cells will fill another two bottles. Now, out of these 4 bottles, one is old which was already filled with cells. So, no. of new bottles filled=3 in 10 minutes.

So, it will take 10 minutes to fill another 3 bottles of the same size.

The time period, T, of a simple pendulum is directly proportional to the square root of the length, d, of the pendulum.

Answer: T= 3.54

Step-by-step explanation:

Step 1

Given that

The time period, T, s doirectly proportional to the square root of the length, d, of the pendulum, we have that

T ∝ $\sqrt{d}$

Introducing the constant of proportionality, we have that

T= K $\sqrt{d}$ .

Step 2

When d=6, T=5, K =?

T= K $\sqrt{d}$ .

5 = k $\sqrt{6}$

5= k x 2.44949

k =5/2.44949

k =2.041

Therefore, when d = 3 , T= ?

T= K $\sqrt{d}$

T= 2.041 x $\sqrt{3}$

T= 3.53511≈ 3.54

Answer:

a = 3.14

b = 6.28

Step-by-step explanation:

The interval where the function is decreasing is where increasing x values result in decreasing y values. The y values peak at the point (3.14, 2) and decrease until the point (6.28, 0) where the function starts increasing again.

Mr.Jones has 160 animal on his Farm.Of these animals,20% are cows,30% are goats ,10% are horses, and the rest are chickens how m

Salsk061 [2.6K]

Answer:

64 chickens

Step-by-step explanation:

Let the total percentage of animals be represented as = 100%

100% = 20% + 30% + 10% + % Chicken

% Chicken = 100% - ( 20% + 30% + 10% )

% Chicken = 100% - 60%

% Chicken = 40%

The number of animals on the farm = 160

The number of chickens on the farm = 40% × 160

= 40/100 × 160

= 64 chickens
