5•6 = 30.
She needs to buy 30 flowers from the store.
Answer:
The answer is below
Step-by-step explanation:
When renting a car two options listed below are given. You need the car for 3 days. How many miles must you travel in order for option 2 to be the better option? Tell me your variable and what it represents. Then use that variable to set up an equation you can solve to get the answer.
Option 1
Daily fee $50
Cost per mile $0.15
Option 2
Daily fee $65
Unlimited miles
Solution:
The equation of a straight line is given by:
y = mx + b; where m is the slope of the line (that is rate of change) and b is the y intercept (value of y when x is 0).
Let x represent the number of miles travelled in one day and let y represent the total cost incurred for travelling x miles.
Therefore, for option 1, the total cost per day is:
y = 50 + 0.15x (1)
For option 2, the total cost per day is:
y = 65 (2)
Since, we want to determine, how many miles must you travel in order for option 2 to be the better, hence:
65 < 50 + 0.15x
15 < 0.15x
x > 100 miles
Therefore for option 2 to be better, the car must travel more than 100 miles per day.
Answer:
the actual hourly percent increase is 6.823 %
Step-by-step explanation:
Given that data in the question;
rate chemical decomposes increasing continuously at 6.6 %,
r = 6.6% = 0.066
actual hourly percent increase = ?
Now,
hourly percent increase = ( - 1 ) × 100%
we substitute
hourly percent increase = ( - 1 ) × 100%
hourly percent increase = ( 1.06823 - 1 ) × 100%
hourly percent increase = 0.06823 × 100%
hourly percent increase = 6.823 %
Therefore, the actual hourly percent increase is 6.823 %
Answer:
products : (2abc) × (– 5ab) ×(– 6c)
2abc×-5ab×-6c
-×-×2×5×6×a×a×b×b×c×c
+60×a²×b²×c²
60a²b²c² is your answer. here -×-=+
