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

x=\frac{(1/3)ft*126ft}{0.25ft}=168 ft

What is t in t/3 = 4/9?
SCORPION-xisa [38]

Answer:

t =  \frac{4}{3}

Step-by-step explanation:

1) Multiply both sides by 3.

t =  \frac{4}{9}  \times 3

2) Use this rule: a/b × c = ac/b.

t =  \frac{4  \times 3}{9}

3) Simplify 4 × 3 to 12.

t =  \frac{12}{9}

4) Simplify 12/9 to 4/3.

t =  \frac{4}{3}

Therefor, the answer is, t = 4/3.

and in decimal form it would be, 1.333333.

aleksandrvk [35]

Answer:

55 Southern deliveries.

Step-by-step explanation:

Let's make a ratio

Northern : Central : Southern : Total

    14        :     44     :       22      :   80

     7         :     22     :       11        :   40

    35        :     110     :      55      :  200

We can see from our ratio, that there are 55 Southern deliveries when 200 deliveries are delivered.
