You can find the perimeter of any closed figure by, measuring the sides and adding all of the sides. After, you have to add all of the sides, including the base together! Hope this is correct

What are all the shapes my quadrilateral Must be and could be if it has a pair of equal sides and a pair of parallel sides

masha68 [24]

If the parallel sides are the same length, then the figure must be a parallelogram. You can prove this by dividing the parallelogram into two triangles, and then using SAS (side angle side) to prove the triangles congruent, which leads to you showing the corresponding angles are the same measure, therefore the other set of sides must be parallel as well.

If the non parallel sides are the same length, then you have an isosceles trapezoid. A trapezoid is any figure with exactly one pair of parallel sides. An isosceles trapezoid is one where the non-parallel sides are the same length. The non-parallel sides are sometimes considered the legs of the trapezoid (and the parallel sides are the bases).

If you have two adjacent sides that are same length, and you have one set of parallel sides, then you could have a trapezoid (not isosceles but just a more generalized trapezoid)

The volume of Solid A is 171.5 m and the volume of Solid B is 500 m, If the solids are similar, find the scale factor of Solid A

Bond [772]

Answer:

The scale factor is $1.429$

Step-by-step explanation:

we know that

If two figures are similar, then the ratio of its volumes is equal to the scale factor elevated to the cube

Let

z----> the scale factor

x----> volume of solid B

y ----> volume of solid A

$z^{3}=\frac{x}{y}$

we have

$x=500\ m^{3}$

$y=171.5\ m^{3}$

substitute

$z^{3}=\frac{500}{171.5}$

$z=\sqrt[3]{\frac{500}{171.5}}=1.429$

Find the slope of the line that passes through the points (2, 4) and (6, 12).

Gnesinka [82]

Answer:

slope of the line passing through these coordinates is 2

Step-by-step explanation:

slope of line :-

=》

$\frac{y2 - y1}{x2 - x1}$

=》

$\frac{12 - 4}{6 - 2}$

=》

$\frac{8}{4}$

=》

$2$

so, the slope of the line is 2

Calculate the interest paid when 4920 is invested at 13% p.a simple interest for eight years

Jlenok [28]

Answer:

I'll setup the problem and you can do the calculations

Step-by-step explanation:

The formula for simple interest:

I = P*r*t

I = interest

P = principle or amount invested

r = interest rate per period (period is a year)

t = number of periods

P = 4920

r = .13

t = 8

Which function has a domain of x>-5?

Rom4ik [11]

Answer:

f(x)=x-5 is a linear function

Step-by-step explanation:

so there are no restrictions to what x can be. The domain is all real numbers. In interval notation, we show that is can be anything from negative infinity through infinity like this: This says that the lower limit of the domain is negative infinity and the upper limit is positive infinity.
