Answer:
2.05 hours
Step-by-step explanation:
Using the given equation with the given time, we have ...
55x +35(2.5) = 200
55x = 112.5 . . . . . . . . subtract 87.5
x = 2.05 . . . . . . . . . . divide by 55
The car spends 2.05 hours at 55 mph.
Answer:
46
Step-by-step explanation:
10%*X=20
X=20/(10%)
X=20/0.1
X=200
23%*200=46
I believe it may be C. Because, the color changing has nothing to do with the reaction you get.
Answer:
The false choices are A, C, and E
Step-by-step explanation:
Let's make an example:
p=1
q=2
s=sqrt(3)
t=sqrt(6)
Since pq=1*2=2, the answer is rational and A is false.
Since pt=1*sqrt(6)=sqrt(6), the answer is irrational and B is true.
Since p/q=1/2=0.5, the answer is rational and C is false.
Since st=sqrt(3)*sqrt(6)=sqrt(18), the answer is irrational and D is true.
Since s/t=sqrt(3)/sqrt(6)=sqrt(1/2), the answer is irrational and E is false.
y=−3x+9 slope of this equation is -3 and y-intercept is 9
Plot the y -intercept first which is 9 and mark the points using the slope which is -3. Join the points. So blue line in the graph is y = -3x+9
y=−x−5 slope of this equation is -1 and y intercept is -5
Plot the y -intercept first which is -5 and mark the points using the slope which is -1 . Join the points. So pink line in the graph is y = -x-5
The intersection point of these two lines gives you the solution.
The coordinates of point of intersection (7,-12)
