Answer:
$0.41
Step-by-step explanation:
1 ice cream cone: $2.75
2 ice cream cones: 2 * $2.75 = $5.50
7.5% of $5.50 =
= 0.075 * $5.50
= $0.4125

Answer:

Step-by-step explanation:
We are asked to find the volume of the cylinder. The formula for calculating a cylinder's volume is: 

We know the height of the cylinder is 8 feet. We are given the diameter, the distance from edge to edge through the center. We want to find the radius, the distance from the edge to the center. 
The radius is half the diameter. 
- r = d/2 
- r= 10 ft/2 
- r=5 ft 
We know both variables (h= 8ft and r=5 ft) and can substitute them into the formula.

Solve the exponent.

Multiply the numbers in parentheses. 


The volume of the cylinder is <u>200π cubic feet and choice C is correct.</u>
 
        
             
        
        
        
Using <u>linear function concepts</u>, it is found that the correct option is:
The amount of calories in a cheeseburger increases by 1.42 for every one gram of fat. The calorie amount estimated by this model is 121 if there are zero grams of fat.
A linear function is modeled by:

In which:
- m is the slope, which represents by how much y changes when x changes by 1.
- b is the y-intercept, which is the value of y when x = 0.
In this problem:
- The explanatory variable fat is the input.
- The response variable calories is the output.
The equation is:

- The slope is of 1.42, which means that the amount of calories increases by 1.42 when the amount of fat increases by 1 gram.
- The y-intercept is of 121, which means that if there are 0 grams of fat, there will be 121 calories.
Thus, the correct option is:
The amount of calories in a cheeseburger increases by 1.42 for every one gram of fat. The calorie amount estimated by this model is 121 if there are zero grams of fat.

Hey there! 
The answer is C. 
First of all, let's assign variables. We can use t for tricycles and b for bicycles. 
Next let's look at the first statement: 
"There are at most 12 bicycles and tricycles in a school playground." 
"At most" means the number 12 will be included in the inequality, so the sum of b and t is at most 12. 
We can write this as b + t ≤ 12. 
Now we can look at the second statement: 
"There are at least 17 wheels altogether." 
"At least" means the number 17 will be included in the inequality. 
Since each bicycle has 2 wheels and each tricycle has 3 wheels, the sum of 2b and 3t is at least 17. 
That can be written as 2b + 3t ≥ 17. 
Our final system of inequalities: 
b + t ≤ 12
2b + 3t ≥ 17 
This matches option C.
Hope this helps!
