<u>Answer:</u>
The correct answer option is ST.
<u>Step-by-step explanation:</u>
We are given a figure of a right angled triangle and we are to determine whether which of the given segments is the projection of QT on RT.
We know that:
QT = QS + ST
Therefore, on RT, ST is the projection of QT since it comes mid way from Q to T.
So the correct answer option is ST.

B
Step-by-step explanation:
In B, the oranges is always 3 times the cups of juice. So it always follows the ratio 3:1.
Answer:
36 + 72
Step-by-step explanation:
The length of the rectangle = diameter of 2 circles = 4 × 3 = 12 mm
The width of the rectangle = 2 radii + distance d between radii ( lower to upper )
Using the right triangle formed by joining the 3 centres with legs 3 and d and hypotenuse 6
Using Pythagoras' identity, then
d² + 3² = 6²
d² + 9 = 36 ( subtract 9 from both sides )
d² = 27 ( take the square root of both sides )
d = = 3
Thus width of rectangle = 3 + 3 + 3 = 6 + 3
Hence
area = length × width
= 12 × (6 + 3 ) = 36 + 72 mm ²
