Answer:

p = 2, q = 3.

Step-by-step explanation:

A perfect cube is in the form $a^{3}$ .

$\frac{6.54.p}{q} = \frac{324.p}{q} = \frac{2^{2}.3^{4}.p }{q}$

To make this fraction a perfect cube, we need to increase the exponent of 2 to 3 and decrease the exponent of 3 to 3.

Conclusion: $p = 2, q = 3$ .

An antique store increases all of its prices by $40\%$, and then announces a $25\%$-off-everything sale. What percent of the ori

Mandarinka [93]

Answer:

105%

Step-by-step explanation:

We'll analyse the question one step at a time

Let the original price be x.

Let y be the 40% increase

$y =x + 40\% *x$

Express as decimal

$y =x + 0.40 x$

$y =1.40x$

Let z be the 25% off sale

$z = (1 - 25\%) * y$

Express as decimal

$z = (1 - 0.25) * y$

$z = (0.75) * y$

$z = 0.75y$

Substitute 1.40s for y

$z = 0.75*1.40x$

$z = 1.05x$

Express 1.05 as a fraction

$z = 105\% * x$

The percentage is 105%

Given condition y = 2x

When x = 1 , y = 2 *1 = 2

When x = 2 , y = 2 * 2= 4

when x = 3 , y = 2* 3 = 6

When x = 4 , y = 2 * 4 = 8

Brad buys a pack of 12 bottles of energy drink for £9.25

BARSIC [14]

Step One
Find the cost of one bottle
12 bottles cost 9.25 pounds.
1 bottle costs x

12 / 1 = 9.25/x Cross multiply
12*x = 1 * 9.25 Divide by 12
x = 9.25 / 12
x = 0.77

Remark
0.77 pounds sterling = 77 pennies

Step Two
find the profit on the sale of one bottle
100 - 77 = 23 pennies

Step Three
Find the % profit on one bottle.

% Profit = (profit on one bottle / Cost of 1 bottle.) * 100%
% Profit = (23 / 77) * 100
% Profit = 29.87% <<<<<<<< Answer.

Will measures the distance around a tree using a tape measure as 48 inches. Use this measure to find the diameter of a cross sec

marin [14]

Answer: Assume the cross section is taken at the same height where the circumference was measured. Then

48/3 = 16 inches, close enough, actually. Trees aren't cylinders.

48 × 7 / 22 inches = 15.2727272

48/3.1415926 = 15.2788747

48/pi = 15.2788745368219522338128412837... ☺️

Step-by-step explanation:

circumference / diameter = pi = 3.1415926......

So diameter = circumference / pi.
