Answer:
- 4 nickels
- 60 mph
Step-by-step explanation:
1. If all were dimes, the value would be $8.00. The value is actually $0.20 less than that. Replacing a dime by a nickel decreases the value by $0.05, so there must be $0.20/$0.05 = 4 nickels.
2. The total of the two speeds is the rate of closure: (420 mi)/(4 h) = 105 mi/h. The speed of the second car is found by subtracting the speed of the first car from this total:
105 mph - 45 mph = 60 mph
M=(y2-y1)/(x2-x1)
(x1,y1)=<span>(−a + 2, b − 3)
</span> (x2,y2)=<span>(a + 2, −b)
then, </span>substituting
m=((-b)-(b − 3))/((a + 2)-(−a + 2))
m=(-2b+3)/(2a)
with
a=/0
The answer is the option d.Perpendicular bisector.
Explanation:
By definition, a circumscribe circle passes through the three vertices of the triangle and to its constrution, you have to draw the triangle and then construct a perpendicular bisector to each side of it. The point where these perpendicular bisectors intersect each other, will be the center of the circle. Then, you should place the compass on the center point to draw the circle.
Answer:
I think the answer is 70
Step-by-step explanation:
40 + 15 = 55 and when you add 15 to 55 you get 70 but this might not be right!
Answer:
False.
Step-by-step explanation:
If M(6, -2) were reflected across the line x = -3, then M' would be (0, -2) making the statement true.
