Mila [183]

Answer:

The profit is $24

Step-by-step explanation:

Step one:

given the expression for the profit made as

$1.25p-0.75p,$

we are told that p is the number of pens, hence for p= 48 by substituting into the expression we can find the profit as

Step two:

Profit= 1.25p-0.75p,

Profit= 1.25(48)-0.75(48),

Profit= 60-36

Profit=24

For which two beverages is the difference between the prices the greatest? what is the difference?

Anton [14]

Answer:

The biggest difference is between fruit juice and lemonade ($0.6).

Step-by-step explanation:

Giving the following information:

items:

fruit juice. $0.89

iced tea. $1.29

lemonade. $1.49

pretzel. $2.50

popcorn. $1.25

First, popcorn and pretzel are not beverages.

<u>Now, we need to find the differences in prices between each beverage and determine the greatest:</u>

Fruit juice to ice tea= 0.89 - $0.4

Fruit juice to lemonade= 0.89 - 1.49= $0.6

Ice tea to lemonade= 1.29 - 1.49= $0.2

The biggest difference is between fruit juice and lemonade ($0.6).

Some fireworks are fired vertically into the air from the ground at an initial velocity of 24.5 meters per second. Find the high

krek1111 [17]

Answer:

The highest point reached by the firework is approximately 30.6 meters

Step-by-step explanation:

The upward velocity of the fireworks is given as 24.5 m/s

The equation of projectile motion for an object fired vertically upwards can be written as follows;

v² = u² - 2·g·s

Where;

v = The final velocity of the motion = 0 m/s at maximum height

u = The final velocity of the motion = 24.5 m/s

g = Acceleration due to gravity = 9.81 m/s²

s = The height reached = (The highest point reached by the firework)

By substituting the values, we have;

(0 m/s)² = (24.5 m/s)² - 2 × 9.81 m/s² × s

Which gives;

2 × 9.81 m/s² × s = (24.5 m/s)² = 600.25 m²/s²

19.62 m/s² × s = 600.25 m²/s²

s = 600.25 m²/s²/(19.62 m/s²) = 30.594 m ≈ 30.6 meters

The highest point reached by the firework is approximately 30.6 meters
