Answer:

27 IN

Step-by-step explanation:

If you want to calculate the perimeter of an irregular trapezoid, there's no special formula - just add all four sides:

Trapezoid perimeter = a + b + c + d

Maybe you've noticed, but it's the formula for any quadrilateral perimeter.

There's also an option that that presents itself with certain special trapezoids - like an isosceles trapezoid, where you need a, b, and c sides. Another example is a right trapezoid, where the length of the bases and one leg are enough to find the shape's perimeter (the last leg is calculated using Pythagoras' Theorem).

How hard must someone pull on the unkown line and inwhat direction to keep the knot from moving ​
dolphi86 [110]

Answer:

4.4N, 263.4°

Step-by-step explanation:

The sum of all forces must add to zero:

The forces in the x-plane:

∑F = 3N + (cos 120°)*5N + x = 0

x = -(3N + (cos 120°)*5N)

x = -0.5N

The forces in the y-plane:

∑F = (sin 120°)*5N + y = 0

y = -(sin 120°)*5N = -√(3/4)*5N = -4.3N

The magnitude of the unknown force U is:

U = √(x² + y²) = √19 = 4.4N

The direction is given by:

tanФ = y/x

Ф = 263.4°

What is the slope of the line that contains the points (-2,7) and (2,3)
Ludmilka [50]

The formula for slope is

\frac{y_{2}-y_{1}}{x_{2}-x_{1}}

In this case...

y_{2} =3\\y_{1} =7\\x_{2} =2\\x_{1} =-2

^^^Plug these numbers into the formula for slope...

\frac{3-7}{2 - (-2)}

\frac{-4}{4} -------------------> Simplifies to -1

                                                ^^^This is your slope

Hope this helped!

We wish to know how much faster Grant rows than Arianna.

d=G-A  and we want our answer is miles/hour so

d=(6mi/36min)(60min/hr)-(3520yd/20min)(mi/1760yd)(60min/hr)

d=10mph-6mph

d=4mph

So Grant rows 4 miles per hour faster than Arianna.
