Answer:
The inequality to represent the situation is and the team must sell at least "Jaguar Cards".
Step-by-step explanation:
Given: The ADMHS football team is trying to raise money to buy new equipment so the players are selling "Jaguar Cards" for each.
If the football team needs to raise at least for equipment.
To find: The inequality to represent the situation and the least number of "Jaguar Cards" the team must sell.
Solution:
Let the ADMHS football team sold "Jaguar Cards" for each.
Now, the football team needs to raise at least for equipment.
So, the inequality to represent the situation is .
Now, on solving we get,
Hence, the inequality to represent the situation is and the team must sell at least "Jaguar Cards".
1) Inequality
2) Equation
Step-by-step explanation:
We need to identify the correct description
1) 7x+9<25
The sign < is called greater than and is an inequality symbol
So, the given term is an Inequality
2) 2x-3=5x+12
This is an equation because we equal (=) sign in it.
Solving the equation we can find value of x.
So, the given term is an Equation

Answer:
2/5 and 3/8
2/5 is greater than 3/8
Step-by-step explanation:
Those parallel lines mean absolute value which means no signs no positive nor negative.
First, we must determine the circumference of the paddle wheel.
The formula for the circumference of a circle is:
c = 2πr
Where r is the radius of the circle. However, we know d = 2r where d is the diameter of the circle.
Therefore:
c = 2rπ = dπ
Substituting 8ft for d gives a circumference of:
c = 8πft
The time it takes to complete 1 revolution can be found using the formula:
t = d/s
Where:
t is the time it takes: what we are solving for in this problem.
d is the distance traveled: we calculated this as 8πft
s is the speed traveled: from the problem we know this is
6.7ft/sec
Substituting and calculating t gives:
t = 8πft / (6.7ft/sec)
t = 1.2πsec
Two find how long it would take for 100 revolutions we can multiply this time by 100
100 × 1.6πsec ⇒ 122.2πsec
If a number is required for the answer we can use 3.14 as an estimate for π giving:
122.2πsec ⇒ 122.2 × 3.14sec ⇒ 383sec
