Answer: 20.5
Step-by-step explanation:
From the measure of the length of the sides of the triangle, 9, 40 and 41 we can infer that the triangle is a right angled triangle. 9-40-41 is a Pythagorean triplet.
In a right angled triangle, the circumradius is half the hypotenuse.
In the given triangle, the hypotenuse = 41.
Therefore, the circumradius is 41÷2= 20.5 units.
Answer:
W=80
Step-by-step explanation:
27= 7+W/4
27-7=W/4
20=W/4
Multiply by 4 on both sides to get rid of denominator 4.
80=W

Answer:
Step-by-step explanation:
Given
Base:
Required
Determine the volume (in litres)
First, we need to calculate the area;
Base on the parameters given, we have:
So:
Answer:
x = 7
Step-by-step explanation:
5x + 9 = 6x + 2
5x - 6x = 2 - 9
-x = -7
x = 7
probe:
5*7 + 9 = 6*7 + 2
35 + 9 = 42 + 2 = 44
