Answer: THe correct option is (C) 15.
Step-by-step explanation: We are given to find the length of SR in the right-angled triangle SRQ as shown in the figure.
Since RT is perpendicular to the hypotenuse SQ, so triangle RTQ and SRT are also right-angled triangles at angle RTQ and RTS respectively.
Also, RQ = 20 units and TQ = 16 units.
Using Pythagoras theorem in triangle RTQ, we have
Now, since RT is perpendicular to the hypotenuse of ΔRST, so we get
Again, using Pythagoras theorem in right-angled triangle RST, we get
Thus, the length of SR is 15 units.
Option (C) is CORRECT.
Answer:
25 percent
Step-by-step explanation:
Let the number of girls be x. Then the number of boys is 3*x = 3x.
the total number of students , i.e. 100 percent the number of students is therefore x + 3x = 4x.
so we have
4x = 100 percent
x = 100/4 percent
= 25 percent
therefore, the percentage of girls is 25

If you would like to know the solution to the equation (x - 2) * (x + 5) = 18, you can calculate this using the following steps:
(x - 2) * (x + 5<span>) = 18
</span>x^2 + 5x - 2x - 10 = 18
x^2 + 3x - 28 = 0
(x + 7) * (x - 4) = 0
1. x = - 7
2. x = 4
The correct result would be x = - 7.

Answer:
The correct answer is option C. 490 units ²
Step-by-step explanation:
Area of cuboid = 2(lb + bh + lh)
From the figure we can see that a rectangular prism.
<u>To find the surface area of prism</u>
Here l = 14 units
b = 7 units and h = 7 units
Surface area = 2((14 * 7) + (7 * 7) + (14 * 7))
= 490 units ²
