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

Consider the function f ( x ) = − 5 x 3 f(x)=-5x3. Determine the average rate of change (ARoC) of f f over the following interva
NeTakaya

Answer:

The average rate of change in the interval (3, 3.5) is -158.75          

Step-by-step explanation:

We are given the following function in the question:

f(x) = -5x^3

We have to find average rate of change over the interval:

x = 3 to x = 3.5

Average rate of change  =

=\dfrac{\delta f(x)}{\delta x}\\\\=\dfrac{f(x_2)-f(x_1)}{x_2-x_1}\\\\=\dfrac{-5(3.5)^3+5(3)^3}{3.5-3}\\\\= \dfrac{-79.375}{0.5}\\\\=-158.75

Thus, the average rate of change in the interval (3, 3.5) is -158.75
