The volume of this prism is
V=l*w*h
rewrite the mixed number as fractions
V= 11 3/5* 9* 12 1/2=
V= 58/5 *9/1* 24/2
V=58*9*24/5*2
V=12528/10=1252 8/10 m^3
or
V=1252.80m^3
S^2 is the only denominator. It is the least common denominator.
Given:
Growth rate = 30% decrease
To find:
The growth factor associated with the given growth rate.
Solution:
The general exponential function is:


Where, a is the initial value, r is the growth rate in decimal and
is the growth factor.
It is given that the growth rate is 30% decrease. So,



Now,




Therefore, the growth factor is 0.7.
Answer:
Option (3)
Step-by-step explanation:
Track is shaped as a rectangle with a semicircle on either side.
Therefore, length of the track = 2(Length of rectangle) + perimeter of a complete circle formed by joining the semicircles on each side.
= 2(96) + 2πr
= 
= 192 + 35π
= 192 + 109.9
= 301.9 m
Since, Jake plans to run four laps.
Therefore, distance covered by Jake = 4 × 301.9
= 1207.6 m
Option (3) will be the correct option.
Step-by-step explanation:
Let the two numbers be X and Y respectively.
<u>We know that</u> :
(a) X = 6Y + 5
(b) X + Y = 75
7Y + 5 = 75
X = 65
Y = 10
