Answer:A
Step-by-step explanation:
To solve for r, you just need to isolate r. To do that, divide by h and π on both sides:
Then, square root both sides to get rid of the 'squared':
Or, if you wanted the answer in terms of π, then just don't divide by it, just divide by h and then square root it.
Answer:
615
Step-by-step explanation:
6150 x 10%
6150 x 0.10 = 615
Step 1: Add 9 to both sides
Step 2: Combine like terms (notice the -9 and 9 cancel out)
Step 3: Flip the inequality
-16 > x - 9
-16 + 9 > x - 9 + 9 ... apply step 1
-7 > x ... apply step 2
x < -7 ... apply step 3
The final answer is x < -7
Any value smaller than -7 will work as a solution
Answer:
LM = 36
Step-by-step explanation:
A quadrilateral is a shape with 4sides. There are different type of quadrilateral such as square, rectangle, trapezium, parallelogram, kite and rhombus.
Perimeter of a quadrilateral is the addition of all 4 sides.
Since the shape is not specified neither is there a diagram, let's assume the quadrilateral is a square.
See attachment for diagram used in solving the question.
Perimeter of square = length+ length+ length+ length
= 4× length
Perimeter of quadrilateral ABCD:
640 = 4×length
Length = 640/4
Length = 160
Perimeter of quadrilateral LMNO:
144 = addition of all 4 lengths
144 = LM + MN + NO +OL
Since we are considering a square all the sides are equal.
LM = MN = NO = OL
144 = 4×LM
LM = 144/4
LM = 36
