Answer:
thus the father is 64 years and son is 37years
Step-by-step explanation:
Let father be X and son be y
X=27+Y...........(I)
X-10=2(Y-10)
putting the value of X from eqn(I)
27+Y-10=2Y-20
Y+17=2Y-20
17+20=2Y-Y
37=y
X=27+Y
X=64
Since we know that the ratio of the model car to the real
car is 1:64, therefore we use this to solve this true length of the real NASCAR
vehicle, let us call this us X, so that:
1 : 64 = 3 inches : X
1 / 64 = 3 inches / X
X = 192 inches

The true length is 192 inches</span>

<em>(</em><em>the</em><em> </em><em>exact</em><em> </em><em>difference</em><em> </em><em>is</em><em> </em><em>10</em><em>.</em><em>1</em><em>,</em><em> </em><em>which</em><em> </em><em>is</em><em> </em><em>"</em><em>about</em><em>"</em><em> </em><em>1</em><em>0</em><em>)</em>
Answer:
11/3 x 4/5 = 44/15 = 2 14/15
A composite number is a number that has at least 2 (if you count 1) whole number factor(if you count 1 as a factor)
whole numbers are numbers like 1,2,3,4 but not including -2,-4,-5
factors are numbers that make up another number so
the factors of 6 are 1,2,3 because 1 times 2 times 3=6
3 is not composite because the factors are 1,3
