Store A has a weekend sale. To the nearest hundredth of a percent, what discount must Store A offer for you to buy the system th
Ad libitum [116K]
We are given the cost of the product along with the markup percentage.  The markup is how the store makes a profit.  To figure out the markup price, simply multiply the "cost to store" by 100% plus the markup percent.

So the markup prices per store is:

A = 162 * 1.4 = $226.80
B = 155 * 1.3 = $201.50
C = 160 * 1.25 = $200.00

Clearly, the best deal is store C.  So in order to choose store A, we want to pay less than the price of Store C, $200.  So if Store A cost $199.99, then we would purchase there instead of Store C.

Therefore, $226.80 - $199.99 = $26.81
If Store A offered a discount of $26.81, we would purchase from Store A.

$26.81/$226.80 = 0.1182

So we would need a discount of 11.82% from Store A.

A construction crew is building a two story house, but they have not built the staircase between the floor yet. The height of th
Naya [18.7K]

Answer:

13.4feet

Step-by-step explanation:

The set up forms a right triangle.

Given

Height of the staircase h = 12 feet

Base of the stairs b = 6feet

Required

Length of the ramp l

Using the pythagoras theorem

l² = h² + b²

l² = 12²+6²

l² = 144 + 36

l² = 180

l = √180

l = 13.42 feet

Hence the length of the ramp to the nearest tenth is 13.4feet

Solve the equation 7/z-1 = 9/z+4
algol [13]

Answer:

z is equal to 18.5

Step-by-step explanation:

When an equation is in the format a/b = c/d, the quickest way to simplify it is to cross multiply.  Each side is multiplied by the other sides denominator, eliminating the division:

\frac{7}{z-1} = \frac{9}{z + 4}\\7(z + 4) = 9(z - 1)\\7z + 28 = 9z - 9\\7z - 9z = -9 - 28\\-2z = -37\\z = 37/2\\z = 18.5

So z is equal to 18.5
