Answer: 15,375 inches

Step-by-step explanation: If there are 123 inches in each group, and there are 125 groups, it is a multiplication operation.

123 × 125 = 15375

The format of the question makes it a bit confusing. I hope this helps.

The endpoints of CD are C(–8, 4) and D(6, –6). What are the coordinates of point P on CD such that P is the length of the line s

Arturiano [62]

If you graph the end points C and D then graph the 4 points at the end it is difficult to tell which points are on CD without a line.
Using the endpoints find the slope (change in y/ change in x) then substitute a point in to find the intercept.
Slope = (-6-4)/(6- -8) = -5/7
Intercept equation (-6) = -5/7 (6) + b
b = -1.71428571429
Graphing the line shows only 2 points on the line (–2.75, 0.25) and (0.75, –2.25)
I am confused by the part, "P is the length of the line segment from D". Were you given a length P to help you determine which point. Using the distance formula to find the length from each point to D doesn't help determine which one is best with the information you have given. The image shows the distances I calculated and the graphed points.
I hope this helps!

What kind of proportion tells that when one quantity is increasing or decreasing, the other quantity also increasing or decreasi

Zanzabum

Answer:

Step-by-step explanation:

Direct proportion is when two numbers move in the same direction. If one of the numbers increase, the other number increases and if the one of the numbers decrease, the other number decreases. The magnitude of the movement of the numbers is bounded by a constant

The expression for direct proportion is

y ∝ kx

where k is the constant

let illustrate with an example :

If x = 10

k = 4

y = 10 x4 = 40

A new soup recipe contains 33 percent less sodium per serving than the old soup recipe. The old soup recipe contained x milligra

masya89 [10]

Answer:

The expressions that could represent the amount of sodium per serving, in milligrams, in the new soup recipe is a) 0.67x

Step-by-step explanation:

Given:

A new soup recipe contains 33 percent less sodium per serving than the old soup recipe. The old soup recipe contained x milligrams of sodium per serving.

Now, to find the expression that could represent the amount of sodium per serving, in milligrams, in the new soup recipe.

The old soup recipe contained sodium per serving = $x\ milligrams.$

As given, the new soup recipe contains 33 percent less sodium per serving than the old soup recipe.

So, to get the amount of new soup recipe sodium per serving we write an equation:

$x-33\%\ of\ x$

= $x-\frac{33}{100} \times x$

= $x-\frac{33x}{100}$

= $x-0.33x$

= $0.67x.$

Thus, the expression $0.67x$ milligrams represent the amount of sodium per serving in new soup recipe.

Therefore, the expressions that could represent the amount of sodium per serving, in milligrams, in the new soup recipe is a) $0.67x.$

Mr. Brown needs to price items that must be sold within 90 days, and he has two options. In option A, Mr. Brown prices items a

Gre4nikov [31]

Answer:

The two options yield the same price at 25 days.

Step-by-step explanation:

With the information provided, you can say that the option A would be equal to option B, which would be:

225-1x=250-2x, where x is the number of days that the item does not sell

Now, you can solve for x:

-1x+2x=250-225

x=25

According to this, the answer is that the two options yield the same price at 25 days.
