48 feet is 12% of
feet?

Answer:

1.   2x + 8y = 10xy

2.   13ab + 15ab = 28ab

Step-by-step explanation:

  This is because for question 2 the "a" and "b" stay together since it's on 13 and 15. So that is why you would get 28ab. For question 1 it's basicly the same but instead, you combine the two to get your answer.

Hope this helps.

Answer:

x/121 + y/9 = 1

Step-by-step explanation:

The major axis is 22 units long, in a horizontal line, and the center is in the middle of the major axis line segment. The center is at the origin. The distance of the whole axis is 22, and its endpoints are 11 units from the center. The axis length is 2a = 22, so a = 11.

Becasue the major axis is horizontal, this ellipse is wider than it is tall.

The minor axis is perpendicular to the major axis and it always shoter (hence the name 'minor'). In this case, it is vertical, is 6 units long, so we say that 6 = 2b, and b = 3.

The ellipse center is (h,k). But in this case, the center is the origin, so h = 0 and k = 0.

The equation for a horizontal ellipse is (x-h)²/a² + (y-k)²/b² = 1, a>b

(x-0)²/11² + (y-0)²/3² = 1

*** x/121 + y/9 = 1

The equation for a vertical ellipse is (x-h)²/b² + (y-k)²/a² = 1, a>b

If the bigger denominator is under 'x' term the ellipse is horizontal, with the longer axis being horizontal.

If the bigger denominator is under the 'y' term, the ellipse is vertical, with the longer axis being vertical.

I'm including 2 files.

The 'brainly ellipse' is form this particular problem.

The 'General Ellipse Info' is a collection of my personal math notes on elleipses.

An odd number cubed is an odd number.

To answer the question, we need to know what odd numbers are

Odd numbers include 1,3, 5,7... and take the general for (2n + 1) where n = 0, 1, 2...

Now, we need to show that an odd number cubed is an odd number.

So, the odd number (2n + 1) cubed is

(2n + 1)³ = (2n + 1)(2n + 1)²

= (2n + 1)(4n² + 4n + 1)

= 8n³ + 8n² + 2n + 4n² + 4n + 1

= 8n³ + 12n² + 6n + 1

= 2(4n³ + 6n² + 3n) + 1

Since (4n³ + 6n² + 3n) is an integer say k, we have that

2(4n³ + 6n² + 3n) + 1 = 2k + 1

Since 2k + 1 is an odd number, 2n + 1 is an odd number and (2n + 1)³ = 2k + 1 which is an odd number.

So, an odd number cubed is an odd number.

Answer: Slope of line = [tex]\frac{1.2}{2}[/tex]

Graph- see picture.

Step-by-step explanation:

Graphs are graphed using y=mx+b

Slope (m) is written as [tex]\frac{rise}{run}[/tex], and y coordinate is up and down, x is left & right.

The y coordinate adds 1.2 every time, so the rise is 1.2.

The x coordinate adds 2 every time, so the run is 2.

The y intercept (b) simply means where the line intercepts the y axis.

It is given that the y intercept is 0.

So, the graphing equation: y= [tex]\frac{1.2}{2}[/tex]x

We don't need to put the y intercept because it is 0!

The graph is attached!

Answer:

Answer is A

Step-by-step explanation:

subtract 15 1/4 and 2 2/3

Formula of volume of a Sphere is : V = 4/3 πr³

Here, Diameter (2r) = 12, so radius (r) = 12/2 = 6 feet

Substitute it into the formula,

V = 4/3 π(6)³

V = 4/3 *216π

V = 288π Ft² [ Answer in the term of π ]

You can also solve it for numeral value by substituting the value of π = 22/7

V = 288 * 22/7 = 905.15 Ft² [ Answer in numbers ]

Answer:

9.09%

Step-by-step explanation:

To find percent decrease you have to use this equation:

[tex]Percent Decrease = \frac{Initial -New}{Initial} x 100[/tex]

Initial = 49.5

New = 45

Plug in and solve:

[tex]PD = \frac{49.5-45}{49.5} x 100\\\\PD = \frac{4.5}{49.5} x 100 \\\\PD = 0.0909 x 100\\\\PD = 9.09[/tex]

The percent decrease is 9.09%

Explanation:

A regular polygon must have all sides of equal length. Also, all angles must be the same measure. This applies to the equilateral triangle in the upper left corner, and the square in the upper right corner. Each angle of the square is 90 degrees even though your teacher didn't use right angle markers.

The middle figure in the top row is not a regular polygon because the sides are not all the same length. Also, the angles are different.

--------------------

In the bottom row, only the first figure is a regular polygon for similar reasons mentioned earlier. The second figure is not a regular polygon because this figure is concave. Only convex polygons can be regular.

The third figure in the bottom row is not regular because one side is longer than the others.
