Answer:
he had 44 books before he bought those 6
Step-by-step explanation:
If you multiply 6 times 2 it is 12, which means if you take away 12 from 100 that is 88. if you divided 88 by 2 (the same thing you did to the 6 to make it 12%) that would be 44.
Answer:
-38
Step-by-step explanation:
1. Isolate y to one side.
y+12=-26
subtract 12 to both sides
y=-38
Surface area of cone is a sum of surface of its base and surface of its mantle.
Surface of its base is a circle which surface we will calculate like this:
Sb = pi*r^2 where r is d/2
Sb = 201m^2
Surface of mantle we calculate by:
Sm = pi*l*r where l is length of side of cone.
l =

= 25.3
Sm = 635.8m^2
Total suface is:
Sb + Sm = 836.8m^2
Answer:
Fraction
Step-by-step explanation:
Fraction is a symbol that represents a part of a whole. It consists of a <em>numerator</em> and a <em>denominator. </em>The numerator is the number above the fraction bar (also known as "Vinculum), while the denominator is the number below the fraction bar. The denominator is the total number of equal parts in a whole.
Examples of Fraction:
,
and
.
In the first example,
, 1 is the numerator, while 2, is the denominator.
<u>Additional Information</u>
When the numerator is smaller than the denominator, the fraction is called <em>"proper fraction."</em> On the contrary, when the numerator is bigger than the denominator, the fraction is called <em>"improper fraction."</em>
Hi there :-)
The formula of the simple interest is
I=prt
your question ask to find r which is interest rate you do that by dividing each side by (pt) to get
R=I÷pt
Now solve to get the interest rate
R=562.5÷(1,500×5)
R=0.075×100 multiply by 100 to get it as percentage
R=7.5%
Hope it helps:-)
