Elena wants to make a scale drawing of her bedroom. Her bedroom is a rectangle with length 5 m and width 3 m. She decides on a scale of 1 to 50. Elena's bedroom door is 0.08 m. How wide should the door be on the scale drawing? Elena's bed measures 4 cm by 3 cm on the scale drawing. What are the actual measurements of her bed

Given:

Bedroom is a rectangle with length 5 m and width 3 m.

Elena's bedroom door is 0.08 m.

Elena's bed measures 4 cm by 3 cm.

Scale of drawing is 1 to 50.

To find:

The width of door on the scale drawing.

Actual measurements of her bed.

Step-by-step explanation:

Scale of drawing is 1 to 50.

It means, the length of sides in drawing is of actual.

Elena's bedroom door is 0.08 m.

1 m = 100 cm

0.08 m = 8 cm

Door on the scale drawing

Therefore, the Door on the scale drawing is 0.16 cm wide.

Elena's bed measures 4 cm by 3 cm on the scale drawing.

Elena's bed actual measurements are

Therefore, the actual measurements of her bed is 2 m by 1.5 m.

cant open file sorry!

step-by-step explanation:

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.
