Answer: it will take 3 hours for both trains to meet.
Step-by-step explanation:
Let t represent the time it will take for both trains to meet.
The two trains travel toward each other from points which are 195 miles apart. It means that after t hours, the total distance that both trains would have covered is 195 miles.
Distance = speed × time
Distance covered by the first train after t hours is
25 × t = 25t
Distance covered by the second train after t hours is
40 × t = 40t
Therefore,
25t + 40t = 195
65t = 195
t = 195/65
t = 3 hours
Answer:
20 cards to his family
Step-by-step explanation:
60 * 1/3 = 60/3 = 20
Answer:
check all below
Step-by-step explanation:
#1
1/6)^3
1/26 so answer 1 on number one
#2 what the heck is this 65+75= 140 not 120
65/120 = 54.16666% * 12600 = 6825 so 3
or 65/140 = 46.428% * 12600 = 5850
#3 number 4 makes the most since sense you get the WHOLE POPULATION
#4 1/5*1/2 or 1/10 = .10 * 100% = 10% or 3
#5
6+2+8+4 = 20
2 red marbles
2/20 = 1/10 = .10 * 100% = 10% or 2
Answer: m∠1=42°
Step-by-step explanation
For this problem, we can separate the triangle into 2 separate triangles to solve for m∠1.
We know that m∠4 is 106°. ∠2 and ∠4 are supplementary angles. You can see that they make a straight line of 180°. We can use this fo find ∠2.
∠2+∠4=180
∠2+106=180
∠2=74°
Now that we know ∠2 is 74°, we can use that to solve for m∠1.
We know that the measures of the angles in a triangle equal to 180°. For the triangle at the bottom, we see ∠3, ∠2, ∠1. Since we know ∠3 and ∠2, we can find ∠1.
∠3+∠2+∠1=180
64+74+∠1=180
138+∠1=180
∠1=42°
The answer is 24.5 by rounding off nearest tenth it becomes 25
PROCEDURE:
1: put all the numbers in numerical order i.e.22,23,24,24,25,26,28,29;
2:now the total amount of values is even, so the median will be the mean of two central values i.e.
(24+25)/2=24.5
now by rounding it off to nearest tenth it becomes 25
