Answer:
90 minutes or 1.30 hours
Step-by-step explanation:
In 72 minutes, Sue ran 12 miles per hour
In 1 minute, Sue ran 12/72 miles per hour
In 60 minutes, Sue ran (12/72)*60 miles per hour
= 10 miles per hour
Remaining miles after completing 12 miles in 72 minutes = (24-12) = 12 miles.
If the mileage decreases to 2 miles per hour, he will now run = (10 - 2) = 8 miles per hour.
Now,
1 hour = 60 minutes
Sue can run 8 miles in 60 minutes
Sue can run 1 miles in 60/8 minutes
Sue can run 12 miles in (60/8)*12 minutes
= 90 minutes or 1.30 hours
The picture in the attached figure
we know that
Applying the law of sines
b/sin B=a/sin A------> a=b*sin A/sin B
b=9
B=15°
A=180-(90+15)-----> A=75°
a=?
a=b*sin A/sin B-----> a=9*sin 75/sin 15----> a=33.59 units
the answer is33.59 units
2x(x - 8) -5(x - 8)
= (x - 8)(2x - 5)
Answer:
$105.
Step-by-step explanation:
After one year her annual rate (AR) will have been $5 (5 percent of her savings (s))
S+AR(5%) --> $100+5 --> $150 after one year.
Its a quadratic. Since x cant be a negative number i used the x=4 answer to plug into the length and width
