Answer: 5.5km
Step-by-step explanation:
The scale given 1 : 25 000 , and it was said that on the map , the distance between two railway stations is 22 cm , this means that the scale of the map is 1: 25000 cm.
The scale 1 : 25 000 means that each centimeters on the map represent 25 ,000 in real life ,therefore , to calculate the real distance between the two railway station , we have
25,000 X 22
= 550000 cm
To convert this to km
Recall that
1 km = 100,000 cm
Therefore we will divide the answer by 100,000 , that is
550000/100000
= 5.5 km
Therefore , the real distance between the two railway stations is 5.5km
Answer:
ABC ~ EDF
Step-by-step explanation:
By the order of the letters, we can determine which triangles are similar.
We know that Angle D is congruent to Angle B. So we have to look for a set of triangles where D and B have the same place holders.
For example, if D is the first letter, then B also has to be the first letter.
The same thing applies for Angle E, and Angle A, since they are congruent to each other.
Wherever Angle E is, Angle A has to be in that same place holder.
Triangle ABC, has Angle B, as the second angle. Therefore we know the similar triangle has to be _D_.
Similarly, Angle A is congruent to Angle E, so we know that Angle E has to be in the first place holder. ED_
By process of elimination we know that the only corresponding angles left are C and F, they must be congruent. So the last thing to write is F.
Triangle ABC ~ Triangle EDF
The only whole numbers that multiply together to equal 22 are 1 x 22, and 2 x 11.
Unfortunately, neither of these pairs add OR subtract to equal 11.
0.75x + 1.5 = 10 <=== ur equation
6(3y+2) + 8(4y+3) + 6y =
Distribute:
18y + 12 + 32y + 24 + 6y =
Combine like terms:
56y + 36
