A scale factor "from A to B" is a number that multiplies some dimension of A to make it equal to the corresponding dimension of B. That is, ...
(scale factor A to B) = (dimension of B)/(corresponding dimension of A)
Your triangles have one corresponding dimension. On triangle A, it is 6 ft. On triangle B, it is 5 ft. Using the above formula, we have
(a) (scale factor A to B) = (5 ft)/(6 ft) = 5/6
The reverse is also true. That is, ...
(b) (scale factor B to A) = (dimension of A)/(corresponding dimension of B)
(scale factor B to A) = (6 ft)/(5 ft) = 6/5
(c) The scale factors are reciprocals of each other.
Mean is the average do 7+10+10+14+29 /5 = 14
median is the middle number so 10
mode is the most frequent number so 10
range is the largest number minus the smallest so 29-7 =22
1. Side PQ, side QR, side PR
2. Angle M, angle S, angle N
3. x<25
ΔXPS is congruent to ΔDNF
Since they only give you two sides of ΔXPS, then you know that:
XP (4y-3)= DN (57)
XS (17x+3) = DF (54)
4y - 3 = 57
4y = 60
y = 15
17x + 3 = 54
17x = 51
x = 3
So the answers are:
x = 3
y = 15
Answer:
a) the number of miles in 1 kilometer
Step-by-step explanation:
The car converts from miles/hour to kilometers/hour, if we see the time measurement (hours) it stays the same in both units.
So to make the conversion<u> it is enough to know how many miles are in one kilometer.</u>
For example, lets convert 10miles/hour to kilometers/hour.
there are 0.621371 miles in 1 kilometer, so if we divide 10miles/hour by 0.621371 we get kilometers/hour units:
Thus to make the conversion between the two units is needed the number of miles in 1 kilometer.
