A direct variation has a constant slope, i.e. (y/x)= constant.
Both of the given two points give a slope of (y/x)=14/2=28/4=7, so the equation of the function is
y/x=7, or simply
y=7x
Answer:
48.5 m/s
Step-by-step explanation:
291/6 = 48.5
That is the exact representation of the constant π. By definition:
π=C/d, where C is the circumference of a circle and d is the diameter.
Answer:
-21.6
Step-by-step explanation:
-5.4
x 4 4x 4=16 so you carry the one to 5x4= 20 + 1 that was carried
-------- keep it negative
-21.6
To solve this problem you must apply the proccedure shown below:
1. You have that:
<span> - The scale model is 11 inches long and 8.5 inches wide.
- The door to her room takes up 1.75 inches.
- The longest wall in Jessica’s actual room is 15 feet long.
2. Therefore, the actual size of the door is:
15 feet=180 inches
1.75 inches(180 inches/11 inches)=28.63 inches
3. If the door in completely open, you must apply the formula for calculate the area of a semicircle:
A=</span>πr²/2
r=28.63 inches
A=π(28.63 inches)²/2
A=1288.11 inches²
The answer is: 1288.11 inches²
