Answer:14
Step-by-step explanation: the ratios of the triangles
Answer:
p = .7
Step-by-step explanation:
3(p+2.55)=9 3/4
Change the fraction to a decimal
3(p+2.55)=9.75
Divide each side by 3
3/3(p+2.55)=9.75/3
(p+2.55)=3.25
Subtract 2.55 from each side
(p+2.55-2.55)=3.25-2.55
p =.7
8 + 7 = 15, so 6 + 9 = 15
The number of elements in a set is the cardinal number of the set
Here the number starts from 1 and continues till 94. So there are 94 numbers. Thus, the cardinal number of the set (1,2,3....94) is 94. The cardinal number of an empty set is 0.
