Answer:

6 7/8 inches

Step-by-step explanation:

The first thing to do is to get the measurements in either inches or feet.  You can't have both.  Let's go from feet to inches.

3 feet = 36 inches

13.75 feet = 165 inches

Now we can set up a proportion to solve for the number of inches the model is:

\frac{model}{real}:\frac{1.5}{36}  =\frac{x}{165}

Now we can cross multiply:

36x = 247.5 so

x = 6.875 or 6 7/8 inches

lana [24]

Answer: E. 4/5

Step-by-step explanation: You have to put the decimal (0.8) over its place value. So in this case 0.8 turns into 8/10. Then you must simplify 8/10, by dividing the numerator (8) and the denominator (10) by the greatest common factor (2). Which gives you the answer 4/5.

Find the missing length. Give all answers in the simplest radical form.​
Solnce55 [7]

Answer:

x = 2\sqrt{74}

Step-by-step explanation:

Since the triangle is right use Pythagoras' identity to solve for x

The square on the hypotenuse is equal to the sum of the squares on the other two sides, that is

x² = 14² + 10² = 196 + 100 = 296

Take the square root of both sides

x = \sqrt{296} = 2\sqrt{74}
