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)

Answer: 9p - 1.5a
Step-by-step explanation:
Your maximum heart rate is about 220 minus your age. But it varies base on age category.
Target heart rate during moderate intensity activities is about 50-70% of maximum heart rate.
According to the question;
Target heart rate for
women = 1/2p(418-4a)
= 209p - 2a ....... (1)
men = 1/2p(400-a)
= 200p - 0.5a .......(2)
To find the difference between the target heart rates for a fit woman and a fit man, take equation 1 from equation 2
(209p - 2a) - (200p - 0.5a)
209p - 2a - 200p + 0.5a
9p -1.5a
Answer:
sonja has 6 books
Step-by-step explanation:
let m = amount of books sonja has
2m+m=18
combine like terms
3m=18
divide
m=6
