My guess for this question would be 1) 5 x 3 = 15 , Hope I helped :)
Answer:
y ≈ 12.6
Step-by-step explanation:
the angle between a tangent and the radius of the circle at the point of contact is 90°
then the triangle with y as a leg is right.
using Pythagoras' identity in the right triangle.
y² + 39² = 41²
y² + 1521 = 1681 ( subtract 1521 from both sides )
y² = 160 ( take square root of both sides )
y = 
≈ 12.6 ( to the nearest tenth )
Answer:
432 tiles
Step-by-step explanation:
First, convert the dimensions of the table to inches.
There are 12 inches in a foot, so multiply 1.5 and 2 by 12.
1.5(12) = 18
2(12) = 24
So, the dimensions of the table in inches are 18 by 24.
Find the area of the table using the formula, A = lw
A = lw
A = (18)(24)
A = 432
So, the area is 432 square inches.
Since each tile is one square inch, the table will fit 432 of these.
So, Ravi will need 432 tiles.
3x^2 = 2x^2 + 25
(Taking 2x^2 to the LHS)
3x^2 - 2x^2 = 25
1x^2 = 25
(Taking square roots on both sides)
x = root25
x = +5 or -5
(as both answers lead to 25
-5 * -5 = +25
+5 * +5 = +25)
You may write the answer as +5 according to your convenience.
