velikii [3]
<span>First, we need to know that the current recommended daily allowance of Vitamin E is 15 milligrams. If Leena ate four tablespoons of peanut butter, thus receiving only 6 milligrams, then we can determine the percentage by first dividing 100 into 15 parts (which gives us 6.66), and then multiply that answer by 6 (6 x 6.66), which gives us precisely 40. Thus, the answer is 40 percent.</span>

\frac{3}{2}x-\frac{3}{4}x=6

\frac{3}{2}x*4-\frac{3}{4}x*4=6*4

6x-3x=24

3x=24

\frac{3x}{3}=\frac{24}{3}

x=8

"x=8 is correct answer."

Hope this helps!

Thanks!

You and a friend want to know how much rope you need to climb a large rock. Your friend is 5.5 feet tall and casts a shadow that
diamong [38]
The concept that is useful in order to answer this item is the concept of ratio and proportion. Let x be the height of the rock from the ground. We use the equation below to answer.
                                    5.5 ft / 18 ft = x ft / 209.5 ft
The value of x from the equation is 64 ft. Thus, they will be needing approximately 64 ft of rope.

vagabundo [1.1K]

The phrases that fit the graph of y = \sqrt x are

  • curve            positive x-values
  • point (1, 1)        x-intercept = 0
  • quadrant I           y-intercept = 0

<h3>How to select the phrases</h3>

The equation of the function is given as:

y = \sqrt x

Next, we plot the graph of the function (see attachment)

From the attached graph, we have the following highlights:

  • All points are in quadrant I
  • The function is a curve
  • It has an x-intercept of x = 0
  • It has a y-intercept of y = 0
  • It has only positive x values
  • It passes through (1,1)

The above represents the phrases that fit the graph
