Oksana_A [137]
I =  / r            where I = current and r = resistance

80 = k / 50 so
k = 400

so we have I = 400/r

when r = 40  
I = 400/40 = 10 amps

aniked [119]
To find the percentage, all we have to do is 35.1/54. When we do that, we get 0.65. Multiply by 100 to get 65. 35.1 is 65% of 54.

Mai wants to make a scale drawing of her kitchen. Her kitchen is a rectangle with length 6 m and width 2 m. She decides on a sca
BigorU [14]

Answer:

Length of scale = 15 cm

Width of scale = 5 cm

Step-by-step explanation:

Dimensions of the kitchen of Mai are given as:

Length of kitchen = 6 m

Width of kitchen = 2 m

Scale to be used = 1 to 40

To find:

The drawing with labeling and dimensions of the scale drawing.

Solution:

First of all, let us understand about the concept of scaling.

Scaling is a method to represent big structures on paper.

For this purpose, we decide a scaling factor and draw the big structures on paper by scaling down (making it small) by using a scaling factor.

Here, the scale factor used is 1 to 40.

i.e. 1 unit on scale is equivalent to 40 units on the actual kitchen.

40 units of kitchen = 1 unit of scale

1 unit of kitchen = \frac{1}{40} units of scale

6 m of kitchen = \frac{1}{40}\times 6\ m = \frac{600}{40}\ cm = 15\ cm

Length of scale = <em>15 cm</em>

40 units of kitchen = 1 unit of scale

1 unit of kitchen = \frac{1}{40} units of scale

2 m of kitchen = \frac{1}{40}\times 2\ m = \frac{200}{40}\ cm = 5\ cm

Width of scale = <em>5 cm</em>

<em></em>

Please refer to the attached image as well for representation of given scale.

charle [14.2K]
I think it’s A. If the first event is 3/5 and the second event is 3/5×2/5, the third will be 3/5(2/5)²=0.096, and the fourth will be 3/5(2/5)³=0.0384 so the 5th will be 3/5(2/5)⁴=0.01536.
