Answer:
A. 8 ft
B. 660 times
Step-by-step explanation:
A. Finding the circumference:
The formula for the circumference is
C = πD where D is the diameter
We are given D = 2.5, and to use π = 3.14, so plug those values in...
C = π(2.5) = (2.5)(3.14)
C = 7.85, which rounds to 8 (the nearest whole number)
B. How many times will it rotate in one mile.
Divide 5,280 by 8 to see how many times the tire will rotate (each time it rotates once the tire travels 8 ft)
5,280/8 = 660
Answer:each session of body sculpting workouts burns 51 calories.
Each session of Yoga workouts burns 83 calories.
Step-by-step explanation:
Let x represent the number of calories that she burnt doing one body sculpting workout session.
Let x represent the number of calories that she burnt doing one Yoga session.
Last week, she burned a total of 517 calories by doing 2 body sculpting workouts and 5 yoga sessions. This means that
2x + 5y = 517 - - - - - - - - - -1
This week, she has completed 2 body sculpting workouts and 1 yoga session and burned a total of 185 calories. This means that
2x + y = 185 - - - - - - - - - - - - 2
Subtracting equation 2 from equation 1, it becomes
4y = 332
y = 332/4 = 83 calories
Substituting y = 83 into equation 2, it becomes
2x + 83 = 185
2x = 185 - 83 = 102
x = 102/2 = 51 calories

Answer:
Skyhigh : 40 friends
Jump it up : 90 friends
Step-by-step explanation:
Given that :
Total amount available to spend = $250
JUMP IT UP:
Party set up fee = $70
Amount paid per person = $2
Number of friends = 90
SKY HIGH:
Party set up fee = $50
Amount paid per person = $5
Number of friends = 40
INEQUALITY :
Party setup fee + amount per person * Number of persons ≤ available amount to spend
SKY HIGH:
50 + 5x ≤ 250
5x ≤ 250 - 50
5x ≤ 200
x ≤ 200/5
x ≤ 40
Hence,
Skyhigh = 90 friends
JUMP IT UP:
70 + 2x ≤ 250
2x ≤ 250 - 70
2x ≤ 180
x ≤ 180/2
x ≤ 90
Jump it up = 90
