Answer:

The perimeter of the second square is 36 inches

Step-by-step explanation:

Given

Represent the sides of the squares with S1 and S2.

So:

$S_1:S_2 = 1 : 3$ --- Scale factor

$P_1 =12$ --- perimeter of the first

Required

Calculate P2, the perimeter of the second

Represent the ratios of the perimeter:

$Scale = P_1 : P_2$

Substitute 12 for P1

$Scale = 12 : P_2$

Equate both scale factors

$12 : P_2 = 1:3$

Convert to fraction

$\frac{12}{P_2} = \frac{1}{3}$

Cross multiply

$P_2 = 12 * 3$

$P_2 = 36$

A prism is a polyhedron that has:

Two bases that are congruent and parallel to each other.
Lateral sides that are parallelograms and link the two bases.
Height that is the distance between the two bases.

From inspection of the give diagram, the figure appears to be a quadrilateral prism with bases STUV and WXYZ.

Parallel line segments

Parallel line segments lie on parallel lines.
Parallel lines are lines on a plane that never meet and are the same distance apart.

a) Segments parallel to XT:

WS, ZV, YU

b) Segments parallel to ZY:

c) Segments parallel to VS:

Planes

A plane is a flat, two-dimensional surface that extends into infinity.
A plane can be named by the letters naming three non-collinear points in the plane.
Parallel planes are planes that never intersect.

d) Planes parallel to plane STU:

e) Planes parallel to plane UVZ:

None

Skew lines

Skew lines are a pair of non-coplanar lines that:

Do not intersect.
Are not parallel to each other.

f) Segments skew to SW:

TU, TV, UV, XY, XZ, YZ

If you roll two number cubes, what is the probability of their sum being equal to a value of seven or higher?

rodikova [14]

If the cubes are die such that each face has numbers from 1 to 6. Rolling two of them, there are 6x6 or 36 ways in which they may be arranged. For their numbers to sum to 7, the numbers should be 1 and 6, 2 and 5, 2 and 6, 3 and 4, 3 and 5, 3 and 6, 4 and 3, 4 and 4, 4 and 5, 4 and 6, 5 and 2, 5 and 3, 5 and 4, 5 and 5, 5 and 6, 6 and 1, 6 and 2, 6 and 3, 6 and 4, 6 and 5, 6 and 6. All in all there are 21 out of 36 and the probability is equal to 7/12.

Carlos bought a $235 water heater with his credit card. He used the water heater for five years before replacing it. He paid off

Mazyrski [523]

First we will find the interest on:

P = $235 principal

t = 2 years

r = 0.1415 annual rate

A = future value

I = A - P the interest

A = P(1 + r)^t

A = 235(1 + 0.1415)^2

A = $306.21

I = A - P

I = $306.21 - $235

I = $71.21

the interest was $71.21.

Next lets find the lifetime cost value:

Lifetime cost value = 306.21 + 5*1.56*52 + 5*0.78*52 = $914.61 (considering that 1 year = 52 weeks)

Now lets find the percentage what percentage the interest is of the lifetime cost:

(71.21/914.61)*100 = 7.79%
