A Christmas jar contains 550 m&ms. Of all the m&ms, 2/5 are green and the rest are red. What is the ratio of green to re
vazorg [7]

Answer:

2:3 unless it wants it in total, then 220:330

Step-by-step explanation:

it gives you the answer with the fraction.  A ratio is basically saying with x:y for every x number of one thing there are y number of another.  In this case we know 2/5 will be green, so how many will be red?  3/5.  So for every 2 greens there are 3 reds.

Another way of looking at it is for the totals.  there are 550 total, so 2/5 of that is green.  2/5 of 550 is 220, while 3/5 is 330  so that means of the 550, the ratio is 220:330.  Kinda like simplifying fractions where 220/550 is the same thing as 2/5

Don't know how to express the value of X as any of those answer choices
Alekssandra [29.7K]

9514 1404 393

Answer:

  x = √(w(w+z))

Step-by-step explanation:

The idea with a right-triangle figure of this sort is that all of the triangles are similar. Here, x is the short side of ∆ABC, and the hypotenuse of ∆BDC. This suggests you want to write a similarity statement involving the short side and hypotenuse.

  BC/AC = DC/BC . . . . . short side/hypotenuse

  BC² = AC·DC . . . . . . cross multiply

  x² = (w+z)w . . . . . . substitute letter values

Taking the square root and rearranging to the form of the applicable answer choice, this is ...

  \boxed{x=\sqrt{w(w+z)}}

Write the rule for the linear function. Remember a function rule is written using f(x)
Marina CMI [18]

Answer:

The rule for the linear function will be:

f(x) = -2x+5

Step-by-step explanation:

We know that linear function can be represented using the slope-intercept formula

y = mx+b

where m is the slope and b is the y-intercept

Given the function is linear

Taking two points from the table to determine the slope

  • (1, 3)
  • (2, 1)

\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}

\left(x_1,\:y_1\right)=\left(1,\:3\right),\:\left(x_2,\:y_2\right)=\left(2,\:1\right)

m=\frac{1-3}{2-1}

m=-2

Using the point-slope form of the line equation

y-y_1=m\left(x-x_1\right)

where m is the slope of the line and (x₁, y₁) is the point

substituting the values m = -2 and the point (1, 3)

y-y_1=m\left(x-x_1\right)

y - 3 = -2 (x-1)

y-3 = -2x+2

adding 3 to both sides

y-3+3 = -2x+2+3

y = -2x+5

or

f(x) = -2x+5

Therefore, the rule for the linear function will be:

f(x) = -2x+5
