Data:
Formula: diameter = 2*radius
Formula: (<span>Circle length)
</span>
<span>
Solving: </span><span>Using the data
</span>diameter = 2*radius
20 = 2*r
2r = 20
<span>Now, replace in the circumference length formula

Answer:
<span>
The exact circumference of the circle is </span>
Answer:
m=49/4
Step-by-step explanation:
Answer:
7.2
Step-by-step explanation:
1. Natalie needed 40 minutes to get to school. In hours 40 minutes is 40/60= 2/3 hour (because there are 60 minutes in an hour). so her speed is 14.4/(2/3)= 14.4*3/2= 21.6 mph.
2. Britany needed 40+20= 60 min. 60 min= 1 hour. so she needed 1 hour her speed is 14,4/1= 14.4mph
3. The difference 21.6-14.4=7.2 is the answer .
The scale for the model length of the fuselage obtained by taking the ratio of the model length and the actual length is 0.125
Actual Length of fuselage = 170 feets
Length of fuselage on model = 21.25
<u>To obtain the scale of the model, we take the ratio of the model length and the actual length</u> :
- Model length / Actual length
- 21.25 feets / 170 feets = 0.125
Therefore, the scale for the model length of the fuselage is 0.125
