Answer:
120 miles
Step-by-step explanation:
Formulate equations.
Distance = rate * time.
D1 = distance from home to airport
D2 = distance from airport to off
D1 + D2 = 150
30 x t1 + 60 x t2 = 150
Divide through by 30
t1 + 2t2 = 5 ----- equation 1
Entire trip took 3 hours
t1 + t2 = 3 -------------------- equation 2
Solve equation 1 and 2 and you get
t1 = 1 hour
t2 = 2 hour
D2 = t2 x speed = 2 x 60
= 120 miles.
Answer:
If Brett's constant rate is greater than Ally's constant rate, he may catch up to Ally before she reaches the end of the path.
Step-by-step explanation:
If Brett's constant rate is faster than Ally's then he could catch up to her because he's going faster than Ally.
Step-by-step explanation:
48{x}^{2} {y}^{2} {z}^{2}
First find the slope using the two points (2,225) and (5,480)
(480-225)/(5-2) = 85
Then find b.
225 = 85*2 + b
225 = 170 + b
55 = b
y = 85x + 55 OR f(x) = 85x + 55 This is the answer to PART B.
Standard form PART A is 85x - y = 55
PART C Plot the y intercept, 55. From the y intercept count the slope 85 up right 1 and plot a point, draw a line through the points
The x axis is the number of days so it would be in intervals of 1.
The y axis is money, I would do intervals of $5
Answer:
$19.60
Step-by-step explanation:
Take the amount and multiply by the tax rate to determine the sales tax
tax = 245 * 8%
Change to decimal form
tax =245*.08
= 19.60
