La ecuación ordinaria de la circunferencia cuyo centro es (-1,5) y su radio es -2/3 es:

Answer:

Step-by-step explanation:

Find the diagram attached.

Given the scale factor of circle A to circle B as 3/4

A:B = 3:4

Total ratio = 3+4 = 7

Area of bigger square A = 45sq. units;

The Total area can be gotten using the expression;

[tex]\frac{4}{7} \times x = 45[/tex] where;

x is the total area of both circles.

Get x;

[tex]\frac{4}{7} \times x = 45\\4x = 7 \times 45\\4x = 315\\x = \frac{315}{4}\\x = 78.75[/tex]

Area of circle B = 78.75 - 45 = 33.75

Let the fraction required be y

45 * y = 33.75

y = 33.75/45

y = 3375/4500

y = 45/60

y = 3/4

Hence the area of circle B is 45 * 3/4 of circle A

b)The ratio of circle A to Circle B is expressed as;

Ratio = Area of circle A/Area of circle B

Ratio = 45/33.75

Ratio = 45 * 100/3375

ratio = 4500/3375

Ratio = 4:3

Hence the ratio of circle A to Circle B is 4:3

Answer:

There should be 424 pages between these volumes.

Step-by-step explanation:

The pages of these volumes are doubled or multiplied twice because of the page numbers being back to back in which there should be 270 pages for volume 1 and 170 pages for volume 2.  Between these pages, you should add 270 and 154 together to get your final answer in which there are 424 pages between the first page of volume 1 and 154th page of volume 2.

x ² + 9x = x (x + 9), so the partial fraction decomposition would be

(7x + 18) / (x ² + 9x) = a/x + b/(x + 9)

where a, b are some constants. To find them, multiply both sides by x ² + 9x :

7x + 18 = a (x + 9) + bx

Solve for a and b :

7x + 18 = (a + b) x + 9a

[ a + b = 7

[ 9a = 18

→   a = 2, b = 5

So

(7x + 18) / (x ² + 9x) = 2/x + 5/(x + 9)

The correct form of the partial fraction decomposition for the expression 7x+18/x^2+9x is  2/x + 5/(x + 9).

Fractions represent equal parts of a whole or a collection. Fraction of a whole: When we divide a whole into equal parts, each part is a fraction of the whole.

Here,

x ² + 9x = x (x + 9), so the partial fraction decomposition would be

(7x + 18) / (x ² + 9x) = a/x + b/(x + 9)

where a, b are some constants. To find them, multiply both sides by x ² + 9x :

7x + 18 = a (x + 9) + bx

Solve for a and b :

7x + 18 = (a + b) x + 9a

[ a + b = 7

[ 9a = 18

→   a = 2, b = 5

So

(7x + 18) / (x ² + 9x) = 2/x + 5/(x + 9)

Step-by-step explanation:

K=98

El=3K    3*98=294

Em=.5El  294*.5=147

K+El+Em=98+294+147=539

Answer:

$539

Step-by-step explanation:

First we need to look at the information given

Karen: $98.00

Emily: Karen x 3

Elizabeth: Emily /2

So if karen donated $98 and emily donated 3 times that all we need to do is multiply it by 3

$98*3= $294

So we now know that Emily donated $294

If Emily donated $294 and elizabeth donated half that all we need to do is divide $294 by 2

$294/2= $147

So we now know that Elizabeth donated $147

All we need to do know is add all three answers together $98+$294+$147=

$539

Answer:

Volume of square pyramid is 3466.6 cm³

Step-by-step explanation:

We are given:

Base edge of square pyramid = 20 cm

Height of square pyramid = 26 cm

We need to find Volume of square pyramid

The formula used is: [tex]Volume=\frac{1}{3}a^2h[/tex]

Where a is base edge and h is height of pyramid

Putting values in formula to find the volume

[tex]Volume=\frac{1}{3}a^2h\\Volume=\frac{1}{3}(20)^2(26)\\Volume=\frac{1}{3}(400)(26)\\Volume=\frac{1}{3}(10400)\\Volume=3466.6 \ cm^3[/tex]

So, Volume of square pyramid is 3466.6 cm³

Answer:

3200

__________________________

the answer is 3200 NOT 3466.6

THE HEIGHT OF THE PYRAMID: 24

The Explanation for height :

the height, half of one side of the square base, and the slant height form a right triangle

using the Pythagorean Theorem...

262=102+h2 (the slant height is the hypotenuse)

676=100+h2

676-100=h2

576=h2

√576=h

h=24 feet is the height of the pyramid

Step-by-step explanation:

v = ( [tex]\frac{1}{3}[/tex] ) · b · h

( [tex]\frac{1}{3}[/tex] ) ( 20 · 20 ) ( 24 )

( [tex]\frac{1}{3}[/tex] ) ( 400 ) · ( 24 ) = 3200cm³

There are four (4) different terms

Step-by-step explanation:

Given;

2x + 3xy - (x + y) + 2

The terms are simplified as follows;

=2x + 3xy - (x + y) + 2

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

collect like terms;

= 2x - x  - y + 3xy + 2

= x - y + 3xy  + 2

Thus, there are four (4) different terms in the simplified expression.

Step-by-step explanation:

Have a good one.

Coefficients are numbers that multiply a variable.

The expression is (c) 6x + 9

The required parameters are:

[tex]\mathbf{Coefficient = 6}[/tex]

[tex]\mathbf{Constant = 9}[/tex]

Let the variable be x.

So, the expression with a coefficient and a constant term is:

[tex]\mathbf{Coefficient \times x + Constant}[/tex]

This gives

[tex]\mathbf{6 \times x + 9}[/tex]

[tex]\mathbf{6x + 9}[/tex]

Hence, the expression is (c) [tex]\mathbf{6x + 9}[/tex]
