dexar [7]
The area of a square floor on a scale drawing is 81 square centimeters, and the scale drawing is 1 centimeter:2 ft. 
so the original area is
A = 81 sq cm ( 2 ft / 1 cm)^2a = 324 sq ft
so the ratio of the ratio the area in the drawing to the actual area  is:
r = 81 sq cm / 324 sq ftr = 1 sq cm / 4 sq ft1 sq cm : 4 sq ft

500 tens equal how many thousands
const2013 [10]
Thousands is a word to describe number with 1000 value and tens used for the number with 10 value. First, you need to count how much 500 tens is. The calculation would be: 500 * 10= 5000.
Then to convert it into thousand, you need to divide it with 1000. The calculation would be: 5000/1000 = 5 thousands

The maker of an automobile advertises that it takes 12 seconds to accelerate from 20 kilometers per hour to 65 kilometers per ho
sp2606 [1]

Answer:

The acceleration is 1.0416 m/s^{2}

Step-by-step explanation:

In order to solve this problem we first need to know the formula for acceleration which is the following.

acceleration = \frac{final.velocity - initial.velocity}{final.time - initial.time}

Since the time acceleration is calculated as m/s^{2} we need to convert the km/h into m/s. Since 1km = 1000m and 1 hour = 3600 seconds, then

\frac{20*1000 }{3600s} = \frac{20,000m}{3600s} = \frac{20m}{3.6s}

**<u><em>Dividing numerator and denominator by </em></u><u><em>1000 </em></u><u><em>to simplify</em></u>**

\frac{65*1000 }{3600s} = \frac{65,000m}{3600s} = \frac{65m}{3.6s}

**<u><em>Dividing numerator and denominator by </em></u><u><em>1000</em></u><u><em> to simplify</em></u>**

Now we can plug in the values into the acceleration formula to calculate the acceleration.

acceleration = \frac{\frac{65m}{3.6s}-\frac{20m}{3.6s} }{12s-0s}

acceleration = \frac{\frac{45m}{3.6s}}{12s}

acceleration = \frac{\frac{12.5m}{s}}{12s}

acceleration = \frac{\frac{1.0416m}{s}}{s}

Finally we can see that the acceleration is 1.0416 m/s^{2}
