A rectangle with an area of 8 ft² is dilated by a factor of 4. What is the area of the dilated rectangle?

prohojiy [21]

Answer:

Option 4) $128\ ft^{2}$

Step-by-step explanation:

we know that

If two figures are similar then the ratio of its areas is equal to the scale factor squared

Let

z------> the scale factor

x-----> the area of the dilated rectangle

y----> the area of the original rectangle

$z^{2}=\frac{x}{y}$

we have

$z=4$

$y=8\ ft^{2}$

substitute and solve for x

$4^{2}=\frac{x}{8}$

$x=16(8)=128\ ft^{2}$

Which equation represents a circle centered at (3,5) and passing though the point (-2,9)

Maru [420]

The equation represents a circle centered at (3,5) and passing through the point (-2,9) will be, $\rm x^2+y^2 -6x-10y-7=0$

What exactly is a circle?

It is a point locus drawn equidistant from the center. The radius of the circle is the distance from the center to the circumference.

Given data;

The Centre of the circle is,(h,k)=(3,5)

The circle traverses (-2,9). Consequently, the radius of the circle r is equal to the separation between (3, 4) and (-2,1).

So radius;

$r = \sqrt{{{(x_2-x_1)^2 + (y_2-y_1)^2}}$

$r = \sqrt{{(9-5)^2+(3+2)^2 }$

$r=\sqrt {41} \\\\ r =6.1 \ units$

Now equation of the circle with center (h,k) and radius r is

$\rm (x-h)^2 + (y-k)^2 = r^2\\\\ (x-3)^2 + (y-5)^2 = (\sqrt{41})^2\\\\ x^2 - 6x + 9 + y^2 - 10y + 25 = 41$

$x^2+y^2 -6x-10y-7=0$

Hence equation represents a circle that will be, $x^2+y^2 -6x-10y-7=0$

Solve the system of equations. y = 7x + 43 y = 2x + 13 a. ( -6, 1) c. ( 6, 1) b. ( 6, -1) d. No solution

xenn [34]

Hello there!

y = 7x + 43
y = 2x + 13

We wanna solve y = 7x + 43 for y in y = 2x + 13

What does that even mean? Well it simply means that we gonna replace y by 7x + 43.

y = 2x + 13

7x + 43 = 2x + 13

Subtract 2x on both sides

7x + 43 - 2x = 2x + 13 - 2x

5x + 43 = 13

Now we can subtract 43 on both sides

5x + 43 - 43 = 13 - 43

5x = -30

Then divide both sides by 5

5x/5 = -30/5

x = -6

Now since we have the value for x, we gonna use that value to find y.

We can do that by substituting -6 for x in y = 7x + 43

But what does that mean? It means that in y = 7x + 43, we gonna replace the x by -6

y = 7x + 43

y = 7(-6) + 43

y = -42 + 43

y = 1

Thus,

The answer is: x = -6 and y = 1

The correct answer is option A (-6,1).

Let me know if you have questions about the answer. As always, it is my pleasure to help students like you.

Rylee has a pack of 40 ballons. In the pack, there are 7 red, 12 green, 11 blue, and 10 yellow balloons. When grabbing a balloon

Alika [10]

Answer:

1/4

Step-by-step explanation:

If she expects yellow, the probability of that happening is 10/40 = 1/4

So if she draws 4 balloons she should expect to get 1 yellow one.
