This ratio is called slope. It tells how quickly a line changes.
Hope this helps!!
Answer:
Step-by-step explanation:
28. Area of the circle = π where r is the radius of the circle.
Given diameter = 14m, therefore radius = = 7m
Now area of the circle = 49 or = 49 * 3.14 * 3.14 = 483.12
29. Volume of cylinder = πh = π* * 3 = 6.75π cu. feet or 21.195 cu. feet
30. A ball resembles a sphere. Volume of the sphere =
Given diameter = 30inches; Therefore, radius = 15 inches
Now, Volume of the ball = = 4500π cu. inches or 14310 cu.inches
12) the answer is A
11 -2v-3=-2-8
8=8
13) the answer is A
because 3 are not equal to -5
or
5v+3=5v-5
5v-5v=-5-3
0=-8 (false)
Answer:
The value of the expression at x=5 is 10
Step-by-step explanation:
The given expression is
Let us simplify this expression.
Distribute -2 over the parentheses, we get
Now, substitute x = 5, we get
On simplifying, we get
The value of the expression at x=5 is 10
14 sec because
In 2sec=600
In4 sec=1200
In6 sec =1800
In 8sec =2400
In10 sec=3000
In12sec=3600
In 14sec=4000
In 14seconds it covers 4000
