Answer:
The ratio of the radius of the smaller watch face to the radius of the larger watch face is 4:5.
Step-by-step explanation:
Let the Area of smaller watch face be
Also Let the Area of Larger watch face be
Also Let the radius of smaller watch face be
Also Let the radius of Larger watch face be
Now given:
We need to find the ratio of the radius of the smaller watch face to the radius of the larger watch face.
Solution:
Since the watch face is in circular form.
Then we can say that;
Area of the circle is equal 'π' times square of the radius 'r'.
framing in equation form we get;
So we get;
Substituting the value we get;
Now 'π' from numerator and denominator gets cancelled.
Now Taking square roots on both side we get;
Hence the ratio of the radius of the smaller watch face to the radius of the larger watch face is 4:5.

Step-by-step explanation:
Let <span>p time in minutes speaking Polish
</span>let <span> h </span> time in minutes speaking <span>Hungarian
</span>
<span>p + h = 5 equation 1
</span><span>190 p - 150 h = 370 equation 2
</span>
multiply eq. (1) by 150 (both sides) <span>
15 0p + 150 h = 750
190p -150 h = 370
add the two eqiations we get :
</span><span>190 p + 150p = 370 + 750
</span><span>
340 p = 1120
p= 1120/ 340 = 3.29
</span><span>3 minutes speaking Polish and 2 minutes speaking Hungarian.
</span>make sure if the number 370 ?? i think it is wrong , it can be 270 because i get a point in the answer
