Answer:
<em>% is the decrease.</em>
<em />
Step-by-step explanation:
<em>To figure out the percentage decrease, you would first subtract the two numbers. </em>
<em />
<em /><em />
<em />
<em>Next, you would divide that number by the total.</em>
<em />
<em /><em />

<em /><em />
<em />
<em /><em />
<em />
<em /><em>% </em><em>would be the decrease percentage. </em>
Common denominator would be 40, 3/4 becomes 30/40, 1/5 becomes 8/40, 5/8 becomes 25/40. 10 30/40 + 6 8/40 + 12 25/40 = 28 63/40 = 29 23/40
Answer:
Step-by-step explanation:
see the figure below
As O is mid point of rectangle
distance between O to AB and DC is same
also distance between O to AD and BC is same
OP and OQ are perpendiculars so it is straight
and OP divides AB into equal segments as distance between O to AD and BC is same
same goes with OQ
Answer:
Circumference of a circle is given by,
Circumference , C= 2π r
Answer: x =
Step-by-step explanation:
According to the pythagorean theorem, a^2 + b^2 = c^2.
As such, 4^2 + x^2 = (4sqrt5)^2
16 + x^2 = 80
x^2 = 64
x = 8.
Thus, the dashed line in the center is 8.
Simply plug this into the pythagorean theorem as well.
8^2+16^2=p^2
p^2 = 320
p = 17.8885438, or sqrt 320
