The grid provided is 10 x 10. So, because the oil is 40% of the liquid in the recipe, you should shade 40 / 100 squares of the grid to represent the 40%.

To find the number of cups of liquid that are not vegetable oil, we can set up a proportion.

40 / 100 = 10 / x

1000 = 40x

x = 25

There are 25 cups of total liquid in the recipe.

Hope this helps!! :)

A 5'6" person walking down the street notices his shadow. If the angle of elevation from the tip of the shadow to the sun is 60°

madreJ [45]

Answer:

The length of the shadow is 3.17 feet .

Step-by-step explanation:

Given as :

The height of the person walking on street = H = 5'6''

∴ 12" = 1 '

So, 6" = $\dfrac{1}{12}$ × 6 = 0.5'

I.e H = 5.5 feet

The angle of elevation of from tip of shadow to sun = Ф = 60°

Let The length of the shadow = X feet

<u>Now, From figure</u>'

Tan angle = $\dfrac{\textrm perpendicular}{\textrm base}$

Or, Tan Ф = $\dfrac{\textrm AB}{\textrm AO}$

Or, Tan 60° = $\dfrac{\textrm H}{\textrm X}$

Or, Tan 60° = $\dfrac{\textrm 5.5 feet}{\textrm X}$

Or, 1.732 = $\dfrac{\textrm 5.5 feet}{\textrm X}$

Or, X = $\dfrac{\textrm 5.5 feet}{\textrm 1.732}$

∴ X = 3.17 feet

So, The length of the shadow = X = 3.17 feet

Hence, The length of the shadow is 3.17 feet . Answer
