Answer:
Building depth = 168 ft
Step-by-step explanation:
we must find the relationship (scale) of the model with respect to the building
.
wide-m (model) = 3 in
deep-m(model) = 4 in
wide-b (building) = 126 feet
deep-b(building) = x
the measures must be standardized
let's convert feet to inches
12 in → 1 feet
3 in → ?, then
3 in → 0.25 feet and 4 in → 1/3 feet
now deep-m = x

Answer: the father is 44 years old now
Step-by-step explanation:
Let Bob's present age be represented by x
Let his father's present age be represented by y
Bob's age is 15 years less than half his father's age. This means that
x = y/2 - 15
x + 15 = y/2
y = 2x + 30
y - 2x = 30 - - - - - - - - - -1
In six years his father's age will be eleven years more than triple Bob's age. This means that
y + 6 = 3(x + 6) + 11
y + 6 = 3x + 18 + 11
y - 3x = 18 + 11 - 6
y - 3x = 18 + 11 - 6
y - 3x = 23 - - - - - - - - -2
Subtracting equation 2 from equation 1, it becomes
x = 7
y = 2x + 30
y = 2×7 + 30
y = 14 + 30
y = 44
