Given:
A number 72.
To Find:
12% of 72.
Solution:
The given problem can be solved using the concepts of percentages and their applications.
1. The given number is 72.
2. x% of a number n is given by the formula,
=> x% of n = ,
3. x% of a number can also be defined as x parts of 100 multiplied by the given number.
4. 12% of 72 can be calculated using the above number,
=> 12% of 72 =
=> 0.12 x 72,
=> 864/100,
=> 8.64.
Therefore, 12% of 72 is 8.64
2x+3x+2=-4(cause y=3x+2)
5x=-6
x=-6/5
f(-6/5)=-8/5
negative 6 over 5
Answer:
(2.8, 0.8)
(0.8, -1.8)
Step-by-step explanation:
1. Home (Xa, Ya)= (8, 6)
San Antonio (Xb, Yb)=(-5, -7)
Xa-Xb=8-(-5)=13
Ya-Yb=6-(-7)=13
Emily starts at 2/5 of the road, make it (Xc, Yc)
Xc= Xa-(Xa-Xb)2/5=8-5.2=2.8
Yc=Ya-(Ya-Yb)2/5=6-5.2=0.8
=> Emily starts at (2.8, 0.8)
2.
Emily ends at 3/5 of the road, , make it (Xd, Yd)
Xd= Xa-(Xa-Xb)3/5=8-7.8=0.8
Yd=Ya-(Ya-Yb)3/5=6-7.8=-1.8
=> Emily ends at (0.8, -1.8)
