Answer:
Let's use the Pythagorean theorem!! I think there are two correct answers, right?
X+93=4x *vertical angles are congruent*
93=3x
x=31
Answer:
12 hours and 40 minutes
Step-by-step explanation:
There are really 2 questions here.
One
1 inch / 400 miles = 9 1/2 inches / x Cross multiply
1*x = 400 * 9.5
x = 3800
Two
The plane goes 300 miles / hour
d = r * t
d = 3800 miles
r = 300 miles / hour Substitute
3800 = 300 * t Divide by 300
t = 3800 / 300
t = 12 2/3 hours
1 hour = 60 minutes
2/3 hour = y
y = 2/3 * 60
y = 40 minutes
Total time = 12 40 minutes or 12.666666 hours.
Total number of cans per week: 8.25 + 15.5 = 23.75 cans
23.75 cans per week x 4 weeks = 95 cans per month
95 cans / 40 cans per package = 2.375 cases per month
Round up to 3 cases.
She needs to buy 3 cases a month
