One ticket to a ride of the merry-go-round at the Sunday Fair costs $2.

Considering the definition of an inequality, the maximum number of tickets that they can buy is 10.

<h3>Definition of inequality</h3>

An inequality is the existing inequality between two algebraic expressions, connected through the signs:

greater than >.
less than <.
less than or equal to ≤.
greater than or equal to ≥.

An inequality contains one or more unknown values called unknowns, in addition to certain known data.

Solving an inequality consists of finding all the values of the unknown for which the inequality relation holds.

<h3>Maximum number of tickets that they can buy</h3>

In this case, you know that

One ticket to a ride of the merry-go-round at the Sunday Fair costs $2.
Jenny and her friends have $36 with them.
After buying tickets to the merry-go-round, they want to be left with no less than $15.

So, they want to spend on the purchase of tickets for the merry-go-round a value less than or equal to $36 - $15= $21.

Being "x" the maximum number of tickets that they can buy, the inequality that expresses the previous relationship is

2x≤ 21

Solving:

x≤ 21÷2

Then, the maximum number of tickets that they can buy is 10.

2. An articulated truck is loaded with cylindrical containers filled with oil. The height of each container is 80cm and the diam

RoseWind [281]

The volume of each container is: 25,133 $cm^{3}$

Given:

height of container (h) = 80 cm

diameter of container (d) = 20 cm

radius = half of diameter = $\frac{1}{2}$ of $20 = 10 cm$

Recall:

Volume of a cylinder = $\pi r^{2} h$

<em>Substitute the values into the formula:</em>

$Volume = \pi \times 10^{2} \times 80 = 25132.74123$

Therefore, volume of each cylinder is approximately 25,133 $cm^{3}$

At store A, 3 pounds of apples cost $12. At store B, the cost is given by y = 2 x where y is the cost in dollars and x is the nu

Elina [12.6K]

Answer:

The unit price is the cost per unit of an item or the cost/price for each item.

1) 4$ per pound. By simplifying the proportion (constant ratio) between the cost, and the pounds of apples. 3 pounds of apples cost 12$ → 3/3 pounds of apples cost 12/3$ → 4 dollars for every pound.

2) 2$ per pound. By evaluating the rate of change (change in the y over x or dependent variable over independent) in the equation: y = 2x. y is the cost in dollars, and x is the pounds of apples. So there are 2 pounds (weight) of apples for every dollar.

3) 3$ per pound. Given a graph with a y scaled by 3, and an x scaled by 1 with a graph y = x or 1 unit up for every unit right. This must be equivalent to y = 3x. Where y is labeled as the cost in dollars, and x as the weight in pounds. So there are 3 dollars for every pound of apples.

4) Store B. Because 2 is less than 3 which is less than 4.

Hope it helps, stay safe and tell me if me wrong! :D
