X: 72÷12=6
Y: 63÷9=7
so B, Y is more compact

Answer:

B) Object Y is more compact.

Step-by-step explanation:

We have 2 objects, X and Y, with their respective masses and volumes.

Liquid    Mass (g)           Volume  (cm³)

   X             72                      12

   Y             63                       9

The density (ρ) is equal to the mass (m) divided by the volume (V).

ρ = m/V

For these objects,

ρX = 72 g / 12 cm³ = 6.0 g/cm³

ρY = 63 g / 9 cm³ = 7.0 g/cm³

The denser an object, the more compact it is. Then, Object Y is more compact.

A triangle has side lengths of (7.8v+2.6)(7.8v+2.6) centimeters, (5.3v+4.5)(5.3v+4.5) centimeters, and (2.4w-6.7)(2.4w−6.7) cent
Citrus2011 [14]

Given:

A triangle has side lengths of (7.8v+2.6) centimeters, (5.3v+4.5) centimeters, and (2.4w-6.7) centimeters.

To find:

The expression which represents the perimeter, in centimeters, of the triangle.

Solution:

We know that

Perimeter of a triangle = Sum of length of all sides of the triangle

Perimeter=(7.8v+2.6)+(5.3v+4.5)+(2.4w-6.7)

Now, combine like terms.

Perimeter=(7.8v+5.3v)+(2.4w)+(2.6+4.5-6.7)

Perimeter=13.1v+2.4w+0.4

Therefore, the expression for perimeter, in centimeters, of the triangle is 13.1v+2.4w+0.4.

In the first year of a 10,000 investment the interest rate was 6%. All earned interest remained invested for the second year, an
Aleks04 [339]

Answer:

13.4%

Step-by-step explanation:

First year:

$10,000*6% = $600

New balance = $10,600

Second Year:

$10,600*7% = $742

$10,600+ $742 = $11,342

Total Return:

Final Balance - Initial balance

$11,342 - $10,000 = $1,342

$10,000*x ÷ $1,342

x = $1,342/$10,000

x = 0.1342

0.134 = 13.4%

Find center and radius<br> (x-3)^2+y^2=8
Flauer [41]

Answer:

<h2>Center: (3, 0)</h2><h2>Radius: 2√2</h2>

Step-by-step explanation:

The equation of a circle in standard form:

(x-h)^2+(y-k)^2=r^2

(h, k) - center

r - radius

We have the equation:

(x-3)^2+y^2=8\to(x-3)^2+(y-0)^2=(\sqrt8)^2

Therefore

the center: (3,\ 0)

the radius: r=\sqrt8\to r=\sqrt{4\cdot2}\to r=\sqrt4\cdot\sqrt2\to r=2\sqrt2
