6 0

When you reflect a point across the x-axis, the x-coordinate remains the same, but the y-coordinate is transformed into its opposite (its sign is changed). If you forget the rules for reflections when graphing, simply fold your paper along the x-axis (the line of reflection) to see where the new figure will be located.

Find the length of x

IRISSAK [1]

To solve you insert into proportions, then cross-multiply and simplify.
But first, add 5 and 6 to get the full side length of the bigger triangle

$\frac{x}{5} x \frac{5.5}{11}$

11x = 27.5
x = 2.5

Hope this helps!

$\bf \textit{volume of a sphere}\\\\
V=\cfrac{4\pi r^3}{3}\quad 
\begin{cases}
r=radius\\
-----\\
r=2
\end{cases}\implies V=\cfrac{4\pi 2^3}{3}\implies V=\cfrac{32\pi }{3}$

A dog kennel owner has 121 ft of fencing to enclose a rectangular dog run. She wants it to

Snezhnost [94]

Answer:

605/12 ft by 121/12 ft

Step-by-step explanation:

So, the dimensions of the dog run would be 5x as the length and x as the width.

The perimeter of this dog run would therefore be :

5x + 5x + x + x = 12x

From here, we know that 12x = 121 ft, so x = 121/12 ft

so the final dimensions of the dog run would be 605/12 ft by 121/12 ft

PART A: Suppose at another time you would like to use the same pancake recipe. You have plenty of all the ingredients except tha

bearhunter [10]

Answer:

see the attachment

Step-by-step explanation:

The repetitive scaling is best handled by a spreadsheet.

We know the scale factor is 3/2, so we can multiply the number of servings and everything else by 3/2. The scaled recipe will make 9 servings.

Since 15 = 6 + 9, we could arrive at this recipe by adding the Part A recipe to the original recipe. Instead, our spreadsheet uses the suggested 15/6 multiplier.

The formula used is shown in the spreadsheet attachment. It is filled to the right and down to cover all of the recipes and ingredients.
