Answer:

3)  1 5/6 mi

4)  a. 4 cm, 6 ft

    b. 6.4 cm, 9.6 ft

    c. same as part a

Step-by-step explanation:

3) Each of the given distances appears twice in the sum of side measures that is the perimeter. Hence by walking the perimeter twice, Kyle walks each of the given distances 4 times. His total walk is ...

  4×1/3 + 4×1/8 = 4/3 + 4/8

  = 1 1/3 + 1/2 = 1 2/6 + 3/6

  = 1 5/6 . . . . . miles

___

4) Since the figure is rectilinear (all angles are right angles, and all sides are straight lines), the sum of partial dimensions in one direction is equal to the whole dimension in that direction.

a. 8 cm = 4 cm + x

  8 cm - 4 cm = x = 4 cm

The distance in the room is ...

  (4 cm)×(1.5 ft/cm) = 6 ft

b. 10.3 cm = 3.9 cm + y

  10.3 cm - 3.9 cm = y = 6.4 cm

The distance in the room is ...

  (6.4 cm)×(1.5 ft/cm) = 9.6 ft

c. The answer to part b was obtained in the same way as the answer to part a.  The unknown dimension is the difference of given dimensions. The actual length in the room is the model length multiplied by the inverse of the scale factor.

How do I simplify this?
ololo11 [35]
Don't get too involved in the 'simplify' part just yet.
It doesn't mean make the problem easier.
It means that when you have the answer, make sure it's in simplest form.
That's why it says "Simplify your answer".
Notice that that's the 2nd instruction.
There's nothing to simplify until you have an answer.

The first thing you have to do here is find the area of a triangle.
Do you remember that formula ? 
I'll bet you do.
The area of a triangle is            (1/2) · (length of the base) · (height)  .

The height and the length of the base are given, right there
in the picture.  Take those, and use them to find the area.

Once you've multiplied the binomials, don't forget about the (1/2).

Finally, you have a trinomial for an answer.
Put the big sweet cherry on top:  Factor it !
I think that's the 'simplify' part.

You may be surprised.
I was when I worked it out just now ... just for you.

Triangle TRI has a base of m centimeters and a height of n centimeters. Rectangle RECT has a length of n centimeters and a width
hram777 [196]
The area of the triangle is 
a=( m x n) /2  in cm² , implies   2xa = m xn
the area of the rectanglle
A= n x m  in cm²
but we know  <span>  2xa = m xn = A,  </span>
that means  the surface of the rectangle is 2 times of the area of the triangle

How would you solve y+1= -4x ? with a step by step solution
polet [3.4K]

Answer:

There are an infinite number of solutions.

Step-by-step explanation:

An equation with 2 unknowns give an infinite amount of solutions, here is just one of the many:

Let y= 3 ( y can be any number)

(3) + 1 = -4x

4 = -4x

x = -4/4

x= -1

(x;y) = (-1;3)

Generally x and y can be any number, just let x or y be any number, then find the other variable based on the value of the number u assumed.
