Answer:
B. Brand A $0.21
Step-by-step explanation:
(round to nearest cent)
Brand A: 21.99/105 = .2094 = .21 ( .2094 rounds to .21)
Brand B: 17.99/80 = .2248 = .22 ( .2248 rounds to .22)
Therefore Brand A is a better buy for $0.21 per load

What is a linear equation in math?
- A linear equation only has one or two variables.
- No variable in a linear equation is raised to a power greater than 1 or used as the denominator of a fraction.
- When you find pairs of values that make a linear equation true and plot those pairs on a coordinate grid, all of the points lie on the same line.
Suppose, time taken by faster maid be x , hours.
So, time taken by slower maid ,
( 4 time faster maid )
Now, time taken by both of the made together is given by ,



which is the time required by faster maid.

Answer:
The approximate lateral surface area of the cone is 251.2 m^{2}
Step-by-step explanation:
we know that
The lateral area of a cone is equal to
LA=(pi)(r)(l)
we have
r=16/2=8 m -----> the radius is half the diameter
l=10 m ----> the slant height
pi=3.14
substitute the values
LA=(3.14)(8)(10)=251.2 m^{2}
