Question;

Use the scale factor 1:12 to find the missing dimension. Great white shark actually lengthy 21ft. Find the model length in inches.

Step-by-step explanation:

Given;

Scale factor = 1:12

Actual length a = 21 ft

Let m represent the model length;

The ratio of model length to actually length is given as;

m/a = 1/12

m = a/12

Substituting a=21 ft;

m = 21/12 ft

Converting to inches;

1 ft = 12 inches

So,

m = 21/12 ft × 12 inches/ft

m = 21 inches

The model length is 21 inches

hey there! : )

4y < -4

we need to isolate y. we can do this by simply dividing both sides by 4.

4y ÷ 4 > -4 ÷ 4

simplify.

y > -1

5 - y > 0

once again, we need to isolate y, so we can start off by subtracting 5 from both sides.

5 - y - 5 > 0 - 5

simplify.

-y > -5

divide both sides by -1.

** remember that when dividing any side by a negative, you must switch the sign! **

-y ÷ -1 < -5 ÷ -1

simplify.

y < 5
