A car passes a landmark on a highway traveling at a constant rate of 45 kilometers per hour.
Let t be the time taken by second car
So t+1 is the time taken by first car
Distance = speed * time
Distance traveled by first car = 45 * (t+1)
second car passes the same landmark traveling in the same direction at 65 kilometers per hour
Distance traveled by second car = 65 * (t)
When second car overtakes the first car then their distance are same
65 t = 45(t+1)
65t = 45t + 45
Subtract 45 t from both sides
20t = 45
Divide both sides by 20
so 
It took 2.25 hours for the second car to overtake first car
Answer:
If it goes through the orgin
Step-by-step explanation:
The answer is B.
Slope is 3; point (2,7)
7=3(2)+B
7=6+B
1=B
M=3
y=3x+1 slope intercept form
3x -y = -1 standard form
Answer:301 watermelons
Step-by-step explanation:
Find out what is percentage of watermelons in all fruits
a+o+hdm+wtm=100%
a=39%
o=28%
hdm=13%
39%+28%+13%+wtm=100%
wtm=100%-39%-28%-13%
wtm=100%-80%
wtm=20%
Lets find out how many of watermelons are using percentage :
20/100*1505=301
Answer:
x = 7
Step-by-step explanation:
When 2 secants are drawn from an external point to a circle.
The product of the external part and the entire secant of one secant is equal to the product of the external part and the entire secant of the other secant, that is
5(5 + x) = 6(6 + 4) ← distribute and simplify both sides
25 + 5x = 6 × 10
25 + 5x = 60 ( subtract 25 from both sides )
5x = 35 ( divide both sides by 5 )
x = 7
