so we're trying to figure what portion of silas' slime is detergent. we know that his slime is a combo of 5 oz glue and 2 oz detergent for a total of 7 oz of slime.

what we want to find is how much of those 7 oz of slime is detergent.

quite simply 2 oz of the 7 is detergent.

to make that into a percent just divide 2 by 7.

2/7 = 0.2857

then move the decimal over two spots to get

28.57 or

D. 28.6%

just remember that percents are just how much makes up the whole.

Which of the following values are in the range of the function graphed below? Check all that apply.

MrRissso [65]

<span>The correct answers are D. 0 and E. 1

A function $f$ from a set A to a set B is a relation that assigns to each element $x$ in the set A exactly one element in the set B. The set A is the domain (also called set of inputs) of the function and the set B contains the range (also called set of outputs). According to this statement the set of values that $y$ take is the range, so as shown in the Figure above:

First.

$y=1 \ when \ x=0$

Second.

$y=0 \ when \ x=-1 \ and \\ y=0 \ when \ x=1$ </span>

2. State a price at which there would be a surplus of cort and explain why.

Annette [7]

A surplus exists when the price is above equilibrium, which encourages sellers to lower their prices to eliminate the surplus. A shortage will exist at any price below equilibrium, which leads to the price of the good increasing. For example, imagine the price of dragon repellent is currently $6 per can.

Solve the following equation 3+x upon 3=x upon 2

ludmilkaskok [199]

$\frac{3 + x}{3} = \frac{x}{2}$

$\frac{3}{3} + \frac{x}{3} = \frac{x}{2}$

$1 + \frac{x}{3} = \frac{x}{2}$

$1 = \frac{x}{2} - \frac{x}{3}$

$1 = \frac{3x}{6} - \frac{2x}{6}$

$1 = \frac{x}{6}$

$1 \times 6 = x$

$6 = x$

Determine if (3,-4) is a solution to y < 2x – 5.

spin [16.1K]

You would plug in the ordered pair into the equation.

1. Put the y value from the ordered pair in the y spot, and the x value in the x spot.

2. add up the x side

Does it equal the y side?

Im a bit confused as the question says “&lt” at least on my end? I’m not sure if that’s just the way it ended up being written or if it means something. Sorry if my answer doesn’t apply :(. But if it does, I hope it helps!

Harmonic mean if a number h such that (h-a)/(b-h)=a/b Prove h is H(a,b) iff satisfies either relation a. (1/a)-(1/h) = (1/h) - (

Fudgin [204]

A.

$\displaystyle\frac1a-\frac1h=\frac1h-\frac1b$
$\implies\displaystyle\frac{h-a}{ah}=\frac{b-h}{bh}$
$\implies\displaystyle\frac{h-a}{b-h}=\frac{ah}{bh}$
$\implies\displaystyle\frac{h-a}{b-h}=\frac ab$

b.

$\displaystyle h=\frac{2ab}{a+b}$
$\displaystyle\implies\frac{h-a}{b-h}=\frac{\frac{2ab}{a+b}-a}{b-\frac{2ab}{a+b}}$
$\displaystyle\implies\frac{h-a}{b-h}=\frac{2ab-a(a+b)}{b(a+b)-2ab}$
$\displaystyle\implies\frac{h-a}{b-h}=\frac{ab-a^2}{b^2-ab}$
$\displaystyle\implies\frac{h-a}{b-h}=\frac{a(b-a)}{b(b-a)}$
$\displaystyle\implies\frac{h-a}{b-h}=\frac ab$

The other direction can be proved by following the manipulations in the reverse order.
