Answer: C. 30/7
Step-by-step explanation: To make an improper fraction out of a mixed one we have to multiply the denominator by the whole number (in this case is 4) and then add the numerator. So 7 x 4 = 28 + 2 = 30, so 30/7 would be the correct answer choice.
Hope this helps!
The awnser is 60 because
It is a cube so it has the smae amout of sides
The formula for the nth term is
a1 + (n-1)d where a1 = first term and d = common difference
That questions answer depends on the size and composition of the horseshoe
It cannot be 30, because the sum of two sides should be more than third side
-not D
10+18=28 <30
it cannot be 6 +10 < 18
it cannot 8
8+10=18
so it is has to be C) 12
12+18>10
10+12>18
10+18>12
answer C. 12 cm
