Answer:
1:6
Step-by-step explanation:
Given that there are 10 circles and 2 triangles, the total number of shapes is equal to 10+2.
10+2=12
Because there are 2 triangles, the ratio of triangles to total shapes is equal to 2:12.
However, this ratio can be simplified because both sides are multiples of 2. Divide both sides of the ratio by 2 to simplify the ratio.
2:12
1:6
Therefore, the simplest ratio of triangles to total shapes is 1:6.
I hope this helps!
Answer:
C
Step-by-step explanation:
The rubber exercise ball is a sphere
the volume of a sphere= 4/3*pi*r3
where r = the radius of the sphere.
from the diagram, the radius = 4.5inches
Therefore, volume of the rubber ball = 4/3*pi*4.5^3 = 381.51 cubic inches

Answer:
(x - 10)(x + 10)
Step-by-step explanation:
x² - 100 ← is a difference of squares and factors in general as
a² - b² = (a - b)(a + b)
Hence
x² - 100
= x² - 10² = (x - 10)(x + 10)
