magdalena creates the drawing shown of a rectangular field . (length : 7.2 cm and height : 3 cm)

she increases all the sides by a scale factor of 4 1/2. what is the area of the new figure?​

Step-by-step explanation:

Let the midpoint formula be expressed as;

M(X,Y) = {x2+x1/2, y2+y1/2}

X = x2+x1/2

Y = y2+y1/2

Get x2

-3 = x2 + 1/2

-6 = x2 + 1

x2 = -6-1

x2 = -7

Get y2;

Y = y2+y1/2

8 = y2+6/2

16 = y2+6

Y2 = 16-6

y2 = 10

hence the coordinate of B is (-7, 10). Option A is correct

Answer:x=9

Step-by-step explanation:

-2x+3=-15

Subtract 3 on both sides:

-2x+3-3=-15-3

-2x=-18

Divide -2 on both sides:

-2x/-2=-18/-2

x=9

If the expression (- 2x + 3) is equivalent to (- 15), then [x] is equivalent to 9.

Given is the equation as follows -

- 2x + 3 = - 15

The given equation is -

- 2x + 3 = - 15

Solving, we get -

- 2x = - 15 - 3

- 2x = - 18

 2x = 18

 x = 9

Therefore, if the expression (- 2x + 3) is equivalent to (- 15), then [x] is equivalent to 9.

Answer:

Step-by-step explanation:

y = 2/3x+4

2/3 is your slope, if you do y2-y1/x2-x1. 6-4/3-0. 2/3

your y intercept is what y is when x is 0. so 4

Answer:

[tex]A=e^{(S+3.404/103.2)[/tex]

Step-by-step explanation:

Step one:

we are told that the relationship between the number of species and the island area is given as

[tex]S=-3.404+103.2ln(A)[/tex]-----------------1

based on any given value for either area or number of species, we can find the other.

say we want to find the land area for a given amount of specie

Step two:

we first make area A subject of the formula.

[tex]S=-3.404+103.2ln(A)[/tex]

let us isolate   [tex]ln(A)[/tex]

[tex]S + 3.404 = 103.2ln(A)[/tex]

Divide both sides by 103.2 we have

[tex](S + 3.404)/103.2 = ln(A)[/tex]

Now, exponentiate both sides using the base e.

[tex]A=e^{(S+3.404/103.2)[/tex]----------------2

for a given value of "S" we can find the area   A based on the above expression.

Step-by-step explanation: The unit rate it 1/0.75

Answer:

the kitchen sink faucet will fill the container faster than the bathroom faucet.

Step-by-step explanation:

I found the unit rate for both faucets in order to be able to compare them.

Kitchen faucet:

.5 gallons in 10 seconds   = 1 gallon in 20 seconds  (0.5 x 2= 1 gal, 10 sec x 2=20 seconds)

.75 gallons in 18 seconds  = 1 gallon in 24 seconds  (0.75 = 3/4     3/4 x 4/3=1 gallon, 18 x 4/3 = 24 seconds)

Answer:

$12

Step-by-step explanation:

It is given that,

Rachael earned $42 for [tex]3\dfrac{1}{2}[/tex]  hours at her job today. It means,

For 7/2 hours, earning is $42

For 1 hour, we divide $42 by 7/2 as follows :

[tex]1\ h=\dfrac{42}{\dfrac{7}{2}}\\\\=\dfrac{42\times 2}{7}\\\\=\$12[/tex]

So, he will earn $12 per hour.

Answer:

$9.99 + $1.29n ≤ $50

Step-by-step explanation:

Given that:

Worth of gift card = $50

Cost of album purchased = $9.99

Cost per song to purchase = $1.29

Number of songs to purchase = n

Inequality to model the situation :

Cost of album + cost per song * (Number of songs) ≤ worth of gift card

$9.99 + ($1.29 * n) ≤ $50

$9.99 + $1.29n ≤ $50

Answer:

The number of cases to be purchased is 2.

Step-by-step explanation:

Giving the following information:

World's Finest Coffee (Decaf) is sold by the case where one case contains 48 6-ounce packages.

First, we need to calculate how many pounds are in each case.

1 pound = 16 ounces

1 case= (48*6)/16

1 case= 18 pounds

Now, the number of cases required each month:

36 pounds = 18*x

x= number of cases

x= 36/18

x= 2

The number of cases to be purchased is 2.

Answer:

455.53cm^2

Step-by-step explanation:

diameter of hemisphere = 10cm

radius of hemisphere = 10/2 cm = 5cm

height of hemisphere = radius of hemisphere = 5cm

height of cylinder = 12cm - 5cm = 7cm

surface area = 2pi(5)7 + pi(5)^2 + 2pi(5)^2 = 455.53cm^2 (5sf)

Answer:

y = -5x - 10

Step-by-step explanation:

Slope-intercept form: y = mx + b

m = slope

b = y-intercept

Now, in your case:

5x + y = -10

Move 5x (don't forget to change the signs!):

y = -5x - 10

Hope this helps!

Answer:

y = 2/3x

Step-by-step explanation:

So we know, when lines are perpendicular that they share the same slope. The slope in the equation of y = 2/3x + 7 is 2/3x. So, we have our slope. Now, we just need to find our b. We plug in the point that you gave us into the equation y = mx + b.

3 = 2/3(2) + b

we multiply the denominator 3 by 2, then divide that by the numerator 2.

3 = 3 + b

subtract 3 from itself and from the opposite side of the equal side 3.

0 = b

in the end, there is no b for this equation. Our answer is

y = 2/3x

Answer:

Step-by-step explanation:

Move -7 to the left, so make 7 positive and & move it next to 25

1. 3x = -10x +25+7

combine 25 & 7

2. 3x=-10x+32

move 10 to the side & combine with 3x

3.  3x+10x=+32

4. 13x = 32

lastly divide 32 from 13

Answer:x=32/13

Step-by-step explanation:

Rearrange terms−7+3=−10+25−7+3x=−10x+25

3−7=−10+25

add 7 to both sides of the equation

then Simplify

add 10 to both sides of the equation the

x=32/13
