Can all one-variable inequalities be simplified to a two-step inequality? HURRY!!!

1 answer:

8 0

Next, solve as you would solve any two-step inequality. Since 2 is added to , you can get by itself on one side of the inequality by subtracting 2 from both sides. Then, to get by itself on one side of the inequality, you need to multiply both sides by 2.D

A concession stand at a sports stadium sells 600 bags of peanuts (each game) if the price of each bag is $4.00. For each $0.25 i

grin007 [14]

Answer:

Price = $4.50

Maximum revenue = $2,430

Step-by-step explanation:

The concession stand sells 600 bags of peanut at $4.00 (600, $4.00).

If there is a $1 increase in price, the number of bags old will decrease by 120, which mens that 480 bags of peanuts will be sold at $5.00 (480, $5.00).

Tracing a linear relationship between price and quantity sold with the two given points:

$m = \frac{5-4}{480-600}\\ m=-\frac{1}{120}$

$P - P_0=m*(Q-Q_0)\\P-4.00=-\frac{1}{120} (Q-600)\\P= -\frac{1}{120}Q +9$

The revenue function is given by the price multiplied by the quantity sold:

$R=Q*P= (-\frac{1}{120}Q +9)*Q\\R=-\frac{1}{120}Q^2 +9Q$

The value of 'Q' for which the derivate of the revenue function is zero, is the output level for which revenue is maximum:

$R'=0=-\frac{2}{120}Q+9\\Q_{max} = 540\\P_{max} = -\frac{540}{120} +9\\P_{max} =\$4.50$

The total revenue of 540 units at $4.50 per unit is:

$R = \$4.50*540\\R=\$2,430$

What is the unit rate of one mile if the map scale is 3/10 in. = 7/8 mile?

Mekhanik [1.2K]

3/10 inches x inches

---------------- = -------------

7/8 miles 1 miles

using cross products

3/10 * 1 = 7/8 * x

multiply by 8/7

3/10 * 8/7 = 7/8 *8/7*x

24/70 = x

divide by 2

12/35

12/35 inches per 1 mile

A parallelogram with a base of y units and a height of x units is changed to have a new base of 3y units and a height of 2x unit

nataly862011 [7]

The formula for the area of a parallelogram is

A=b*h where b=base and h=height

if the base were to increase by 3times and the height were to increase by 2 times then
6A=b*h
The area of the parallelogram would be 6 times larger

So if the original area was 47units², then the new area would be

47*6=282units²

Answer=282units²
