Answer:
12r/t
Step-by-step explanation:
Answer is 9
To get this answer, we replace h with 2, and replace r with 7. This is because h = 2 and r = 7 is given to us
So
h+r = 2+7 = 9
Answer: 1.5miles/hour
Step-by-step explanation:
Answer:
A is b/c the 2 minutes and 54 seconds are 174 seconds and the .29 also gets carried over, so it is 174.29. (You are converting minutes to seconds [60 seconds=1 minute])
B the average time of the four runners would be 43.5725 seconds, b/c 174.29/4=43.5725
Answer:
Right option is (D).
ΔABC and ΔDBE are similar triangles by side angle side similarity postulate.
Step-by-step explanation:
We have given,
Two triangles ΔABC and ΔDBE such as :

This relation will contribute to side side similarity.
Also,
∠B = ∠B , This will contribute as an angle similarity .
So combining above two relations,

and ∠B = ∠B
we can conclude that the triangle ΔABC and ΔDBE are similar triangles by side angle side similarity postulate.
Hence the right option is (C)
