Create two equations:
Oxford: 51 + 7c
Sullivan: 53 + 5c
C is the number of charms.
Now set the two equations equal to each other and solve for c:
51 + 7c = 53 + 5c
Subtract 5c from each side:
51 + 2c = 53
Subtract 51 from each side:
2c = 2
Divide both sides by 2:
C = 2/2
C = 1
When she buys 1 charm the price will be the same.
Theprice would be 51 + 7 = $58, or 53 + 5 = $58
The cost of the bracelet will be $ 58 if Vivian adds 1
charms to it.
Answer:
y = -0.005x² + 50
Step-by-step explanation:
The diameter is 200 feet, so the parabola has roots at (-100, 0) and (100, 0). The maximum height is 50, so the vertex of the parabola is at (0, 50).
Using vertex form of a parabola:
y = a (x − h)² + k
y = a (x − 0)² + 50
y = ax² + 50
Plugging in either root:
0 = a (100)² + 50
a = -0.005
y = -0.005x² + 50
Answer:
A=102 and B=0
Step-by-step explanation:
Sub values for X and Y into equation, put into your calculator and you will get the correct answer.
Answer:
54 miles/hour
Step-by-step explanation:
His rate in miles per hour will be also his speed: to calculate the speed, we just need to divide the total number of miles travelled by the total number of hours, so we will have the average speed in the course:
Speed = 216 miles / 4 hours = 54 miles/hour
So the rate Max travelled is 54 miles per hour.
