(-5/8)(X) = -0.4
(-5/8)(X) = -4/10
X = (-4/10) / (-5/8)
X = (4/10) / (5/8)
X = (4/10)(8/5)
X = (2/5)(8/5)
X = 16/25
Letter D
Answer:
For every pound that the package weight increases, the price of sending it increases by $3.80.
Step-by-step explanation:
The coefficient 3.80 multiplies the variable x (package weight), so if x is 1 pound the cost increase $3.80, if x is 2 pound the cost increase 2*3.80 = $7.6, and so on. Generally speaking, for every pound that the package weight increases the cost increases by $3.80.
Answer:
r = 3 inches
Step-by-step explanation:
The formula for the volume of a sphere is the following:
V = (4π/3)r^3
You know the volume so plug that in for V:
36π = (4π/3)r^3
27 = r^3 (multiply by 3/4π to get r^3 by itself)
r = 3 (you take the cube root of r and 27 to get the value of r)
Hope this helps :)
Answer:
Step-by-step explanation:
Since we're dividing the polynomial by 
, we'll be using -1 to start the division.
Before setting the division up, let's list the coefficients of 
from descending powers and the constant.
The coefficient of 
is 3
Since we don't see an 
, the coefficient will be 0.
The coefficient of is 5.
Lastly, the constant, which is the term without the is -1.
Refer to the attached picture before continuing.
After referring to the picture, we now have the coefficients for the quotient.
The coefficient of is 3.
The coefficient of is -3.
The constant is 8.
Lastly, since the last number is not zero, it's the remainder just like regular division. This can be tricky to remember, but -9 is not the actual remainder.
The remainder is actually 
.
Now putting all the pieces together, we get:
Answer: 15% , you divide the Numerator by the Denominator and you will get a decimal of . 15 then you multiply that by 100 and you will get your percentage which in this case is 15%
