pashok25 [27]

Answer: 9 yards

Step-by-step explanation:

Given

The maple tree is 16 yards tall and its shadow is 12 yards tall

\Rightarrow \cos x=\dfrac{12}{16}

For the tower also, the angle made by the tower and its shadow is x

Suppose the length of the shadow is y

\Rightarrow \cos x=\dfrac{y}{12}

Substitute the value of \cos x

\Rightarrow \dfrac{y}{12}=\dfrac{12}{16}\\\\\Rightarrow y=9\ \text{yards}

It takes 0.5 gallon of cream to make 1 pound of butter. How much cream would you need to make 2.5 pounds of butter?
Natasha_Volkova [10]
1.25 gallons


so we know 0.5 gallons makes 1 pound, and we know that there are at least 2 pounds of butter made.


so we know that there is 1 full gallon of cream used.


however, there is also .5 pounds of butter, so we need to find out the other half.



to do this, we need to split the .5 gallons of cream in half, making 0.25



then, we add 1 + 0.25 gallons to equal 1.25 gallons of cream needed to make 2.5 pounds of butter
