The short answer is: when their fractions add up to full integers.
For examples, two halves make up a whole, or
so the mixed numbers with those will add up to full integers:
but if they don't add up to an interger, the whole sum won't be an integer:
Answer:
Out of all the options that are presented above the one that represents the best definition of the probability of a certain outcome of an event is answer choice
D. Successful outcome divided by possible outcomes
HOPE THIS HELPED!!!!! XD
If we say:
x = the smaller numbers we want to find
y = the larger number we want to find
Then, we can formulate two equations using the information given:
x + y = 68 [1]
y - 4x = 3 [2]
Now, we can solve simultaneously:
Rearrange [1] & [2] in terms of y:
y = 68 - x [1]
y = 4x + 3 [2]
Now equate them and solve for x:
68 - x = 4x + 3
5x + 3 = 68
5x = 65
x = 13
Sub x-value into either [1] or [2]:
y = 68 - (13)
y = 55
Answer:
A
Step-by-step explanation:
The surface area of the sphere:
A = 4 r² π
1 ) r = 60 m;
A = 4 · 60² π = 4 · 3600 π = 14,400 π m²
2 ) Diameter of 14 cm:
r = 14 cm / 2 = 7 cm
A = 4 · 7² π = 4 · 49 π = 196 π cm²
