1 answer:

3 0

Ok so it could be
1. $\frac{2}{3 times 5}$
2. 3 timies $\frac{2}{5}$

ok if 1. then
$\frac{2}{3 times 5}$ = $\frac{2}{15}$

if 2. 3 timies $\frac{2}{5}$ = $\frac{6}{5}$

Draw at least six different sized rectangles that have an area of 64 square units

olga_2 [115]

Let

x------> the length of the rectangle

y------> the width of the rectangle

we know that

The area of a rectangle is equal to

$A=x*y$

$A=64\ units^{2}$

$x*y=64$ --------> equation 1

let's assume different values of x to get the different values of y

case 1) For x=64 units

substitute in the equation 1

$x*y=64$

$y=64/x$

$y=64/64$

$y=1\ units$

the dimensions of the rectangle are 64 units x 1 unit

see the draw in the attached figure N 1

case 2) For x=32 units

substitute in the equation 1

$x*y=64$

$y=64/x$

$y=64/32$

$y=2\ units$

the dimensions of the rectangle are 32 units x 2 units

see the draw in the attached figure N 2

case 3) For x=16 units

substitute in the equation 1

$x*y=64$

$y=64/x$

$y=64/16$

$y=4\ units$

the dimensions of the rectangle are 16 units x 4 units

see the draw in the attached figure N 3

case 4) For x=30 units

substitute in the equation 1

$x*y=64$

$y=64/x$

$y=64/30$

$y=\frac{32}{15} =2\frac{2}{15} \ units$

the dimensions of the rectangle are 30 units x 2 (2/15) units

see the draw in the attached figure N 4

case 5) For x=40 units

substitute in the equation 1

$x*y=64$

$y=64/x$

$y=64/40$

$y=1.60\ units$

the dimensions of the rectangle are 40 units x 1.60 units

see the draw in the attached figure N 5

case 6) For x=60 units

substitute in the equation 1

$x*y=64$

$y=64/x$

$y=64/60$

$y=\frac{16}{15} =1\frac{1}{15} \ units$

the dimensions of the rectangle are 60 units x 1 (1/15) units

see the draw in the attached figure N 6

1 1/2 * 3/4 =

Change 1 1/2 to an improper fraction = 3/2

3/2 * 3/4 = 6/4 * 3/4

6/4 * 3/4 = 18/4 = 4 2/4 = 4 1/2

The answer is 4 1/2.

Hope this helped☺☺

A jet travels 4680 miles against the wind in eight hours and 5720 miles in the wind in the same amount of time what is the rate

Kryger [21]

9514 1404 393

Answer:

jet: 650 mph
wind: 65 mph

Step-by-step explanation:

The speed against the wind is ...

4680 mi/(8 h) = 585 mi/h

The speed with the wind is ...

5720 mi/(8 h) = 715 mi/h

The speed of the airplane in still air is the average of these speeds:

(585 +715)/2 = 650 mi/h . . . speed in still air

The speed of the wind is the difference between the airplane speed and the speed in the wind:

715 -650 = 65 mi/h . . . speed of the wind

_____

Additional comment

If p and 'a' represent the speeds of the plane and the air, the speeds with and against the wind are ...

p + a = with

p - a = against

If we average these, we get ...

((p +a) +(p -a))/2 = (with + against)/2

p = (with + against)/2 . . . . . . . the formula we used above
