Answer:
The initial value of 600 is larger and larger by 24.
Step-by-step explanation:
First of all a 20% decreased of 600.
So, the new value will be 
.
Now, then it is increased by 20% i.e. 480 will be increased by 20%.
So, the new value will be 
.
Therefore, the initial value of 600 is larger and larger by (600 - 576) = 24. (Answer)
Answer:
yes he did make it, when he left at 17:00 he had 3:00 hours to make it to the party. if you divide 200/80=2.5 meaning he's able to make it in 2.5 hours.
Answer: 895 phones
Step-by-step explanation:
Given that :
The function : y = 1.28e^1.31x ; is used to model the number of camera phones shipped since 1997
y = number of camera phones ; x = number of years since 1997
The number of camera phones shipped in the year 2002 can be obtained thus ;
x = 2002 - 1997 = 5 years
y = 1.28e^(1.31 * 5)
y = 1.28e^6.55
y = 1.28(699.24417)
y = 895.03254
y = 895 phones
First, make up some variables to represent the number of Girls and Boys in the choir.
B = number of boys
G = number of girls
You know that there are 4 times as many girls in the choir as boys. Therefore, the equation you can write is:
If you cross-multiply, then you get the simplified equation:
G = 4B
Intuitively this makes sense since if you multiplied the number of boys in the class by 4, that would be equal to the number of girls you have.
Now, we know that the total class size is 60. So girls plus boys equals 60:
G+B = 60
To solve the equation, replace the G in this equation with the replacement you found before, 4B.
G + B = 60 -->
4B + B = 60 -->
5B = 60 -->
B = 12
However, you are trying to find the number of girls, so plug the answer back into your equation.
G + B = 60 -->
G + 12 = 60 -->
G + 12 -12 = 60 - 12 -->
G = 48
The number of girls you have is 48.
Answer:
Segment BC = 36 mm or 3.6 cm
Step by Step Explanation:
There are 10 mm in 1 cm
meaning that segment AC is 40 mm long
if AB is 4 mm and it is one part of the two, then we need to subtract that from the total to find out what is left.
40 - 4 = 36
Segment BC = 36 mm or 3.6 cm
