Answer:
c=8p
Step-by-step explanation:
So, we know that 1 pound of chocolate will cost $8. Felipe is going to buy "p" pounds of chocolate, and "p" means "any number"; so Felipe is going to buy any number of pounds of chocolate.
The formula we would use to calculate this is cost of one pound of chocolate multiplied by number of pounds of chocolate. And the way we can form this algebraically is by writing c=8p.
The "c" stands for total cost and we don't have to put the multiply sign when using algebra, as long as the figures are touching.
Answer:
-10x +25
Step-by-step explanation:
–5(2x – 5)
Distribute
-5 * 2x - (-5) * 5
-10x +25
When you cut the apples into thirds, each apple gives you 3 pieces of equal size.
1 apple = 3 pieces
4 * 1 apple = 4 * 3 pieces
4 apples = 12 pieces
The figure consists of a rectangle and a circle.
first lets find the sides of the triangle
sides of the triangle are 4+4=8 and 3+1=4
therefore area of the rectangle is 8*4=32
now area of semicircle =πr^2/2 = π2^2/2=2π=6.3
we have to add the area of rectangle with the area of semicircle
this is because it the given figure no part of area of circle and rectangle are in common.
therefore total area of given figure = 32+6.3=38.3
Answer: The level of the dose be after 3 hours= 0.03125 mg.
Step-by-step explanation:
General exponential decay equation : 
, where A = initial value , r= rate of decay , x =Time period.
Here, drug’s effectiveness is decreasing exponentially.
AS per given , we have
A= 250 mg
x=3
r= 95% = 0.95
Then, 
Hence, the level of the dose be after 3 hours = 0.03125 mg.
