Answer:
The answer to the question is
Shawn has to wait for 3 minutes for Jason to meet him at 2 miles away from the station
Step-by-step explanation:
To solve the question, we note the variables
Bike speed = 20 mph
Start point of Jason = 1 mile away from the station
Starting point of Shawn = 2 mile away from the station
Total miles away from station = y
Direction of biking = away from the station
Therefore if they both start biking at the same time, Shawn is ahead of Jason
Riding speed of Shawn = Riding speed of Jason = 20 mph
That is Shawn has to wait for 1/20 hr or 3 minutes for Jason to meet him at 2 miles away from the station
Through (2, 5); perpendicular to y = (-2/7)x - 3
first, you should know that the slopes of parallel lines are the same. the slopes of perpendicular lines are opposite reciprocals of one another. in this case, because you need to find a perpendicular line, you'll want to find the opposite reciprocal of (-2/7)
change the sign and flip the fraction: your new slope is 7/2
from there, you just plug it into point-slope form:
y - y1 = m(x - x1)
y - 5 = (7/2)(x - 2)
then you can solve it further to bring it into slope-intercept (y = mx + b):
y - 5 = (7/2)(x - 2)
y - 5 = (7/2)x - 7
y = (7/2)x - 2 is your answer.
Answer:
1 9/50
Step-by-step explanation:
So, /(100÷2) = 59/50 when reduced to the simplest form. As the numerator is greater than the denominator, we have an IMPROPER fraction, so we can also express it as a MIXED NUMBER, thus 118/100 is also equal to 1 9/50 when expressed as a mixed number.
Answer:
a=2
Step-by-step explanation:
ax-8=x+2
when x=2
2a-8=2+2
2a=4+8
2a=12
a=12/2=6
Answer:
1. Radius: 3 Diameter: 6 Circumference: 18.85 Area: 28.27
2. R: 6 D: 12 C: 37.7 A: 113.1
3. R: 9 D: 18 C: 56.55 A: 254.47
4. R: 2.4 D: 4.8 C: 15.08 A: 18.1
5. R: 3.5 D: 7 C: 21.99 A: 38.48
6. R: 7 D: 14 C: 43.98 A: 153.94
Step-by-step explanation:
Radius is half of diameter. Diameter is double radius. Circumference is 2 times pie times radius. Area is pie times radius squared.
