Answer:

16 cm

Step-by-step explanation:

Suppose that <em>x</em> is the original width. If that original width is enlarged by a scale factor 5/2 that means that <em>x</em> is multiplied by 5/2 and after that multiplication we obtained new width, 40 cm.

Therefore,

x*(5/2) = 40

We multiply the equation by 2 and obtain:

x*5 = 40*2

5x = 80

Now we divide the equation by 5 and obtain:

x = 80/5

x = 16

We obtained that <em>x</em>, the original width was 16 cm

Rico thinks of a number between 30 and 40 that is represented by
Anna007 [38]
Hello,

x,y,z∈ IN

x=\frac{3}{4}*y
y=\frac{1}{3}*z

140
46\leq\ y\ \leq\ 50 ==>\ \frac{46*3}{4}\leq\frac{3y}{4}\leq\frac{50*3}{4}
35\ \leq\ z\ \leq\ 37==>
 x∈{35,36,37}
 y∈{47,48,49}
 z∈{141,144,147}

We must go futher:

if x=35 then y=4*35/3=46.666 not good , not whole
if x=36 then y=4*36/3=48 ok
if x=37 then y=37*4/3=49.333.. not good

So there is only one solution (36,48,144) for (x,y,z)

No problem with z for z=3/1*4/3*x=4x ==>whole.

Mrac [35]

Answer:

Manisha spent 8 minutes and 24 seconds in a week climibing the stairs of her house.

Step-by-step explanation: (totally my work, not copied)

Convert seconds to minutes.

60x8=480

60x9=540

so, 8 minutes

Find the remaining seconds.

504-480=24

Add remaining seconds to minutes

24sec+8min=8min24sec

So hence, your answer is 8 Minutes and 24 Seconds

Manisha spent 8 minutes and 24 seconds in a week climbing the stair of her house.

Thanks!

Divide the following complex numbers: (1+i)/(2-5i) ??
Radda [10]

Given : \frac{(1 + i)}{(2 - 5i)}

Multiplying and Dividing with (2 + 5i)

\implies\frac{(1 + i)(2 + 5i)}{(2 - 5i)(2 + 5i)}

\implies \frac{(2 + 5i + 5i^2 + 2i)}{(4 - 25i^2)}

We know that i² = -1

\implies \frac{(2 + 7i - 5)}{(4 + 25)}

\implies \frac{-3 + 7i}{29}

\implies \frac{-3}{29} + \frac{7}{29}i

Option C is the Answer
