Twice the number G is 2×G.
The difference between 2G and 10 is 24.
2G - 10 = 24
2G = 24 + 10
2G = 34
G = 34/2
G = 17
Answer:
The length of the sides are 8 , 32 , 36
Step-by-step explanation:
Ratio of sides = 2 : 8 : 9
The sides are 2x , 8x , 9x
Perimeter of triangle = 76 inches
2x+ 8x + 9x = 76
19x = 76
x = 76/19
x = 4
2x = 2*4 = 8
8x = 8 * 4 = 32
9x = 9 * 4 = 36
Answer:
C. 55
Step-by-step explanation:
Since all angles in a triangle add up to 180°, we have:
40 + y + y + 30 = 180
2y + 70 = 180
2y = 110
y = 55
Answer:19, 81, 45
Step-by-step explanation:
The surface area of a sphere is
where r is the radius;
The circumference is
so that
using this value we can evaluate the surface area of 1 ball as:
For 100 ball you get:
