Someone help please!!!!
MAXImum [283]

Answer:

60cm²

Step-by-step explanation:

as the green and blue box are squares they will have the same sides, length.

so all the sides in the green and blue squares are 3

the pink and orange rectangles : the longer is 7 the shorter one is 3

for the top length of the whole shape is = 7 +3 = 10

side length of the shape is 3 + 3= 6

so then you do 6 x 10 = 60

60 cm² is the answer :)

The number of cows is given by

14\cdot 2^{\frac{y}{5}}

So, after k years, the number of cows will be

14\cdot 2^{\frac{y+k}{5}}

We want this number to be twice as much as the original:

14\cdot 2^{\frac{y+k}{5}} = 2(14\cdot 2^{\frac{y}{5}})

First of all, we can cancel 14 from both sides:

2^{\frac{y+k}{5}} = 2\cdot 2^{\frac{y}{5}}

Finally, on the right hand side, we can use the exponent rule

a^b\cdot a^c=a^{b+c}

to get

2^{\frac{y+k}{5}} = 2^{\frac{y}{5}+1}

To solve this equation, we must impose that the two exponents are the same:

\dfrac{y+k}{5} = \dfrac{y}{5}+1 \iff \dfrac{y+k}{5} = \dfrac{y+5}{5}

And clearly this is true if and only if k=5. So, it will take 5 years for the cow heard to double in number.

You can do the exact same steps to find the doubling time for the sheeps.
