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:
Step-by-step explanation:
Answer:
15. Area of parallelogram = bh
b = 9m
h = 4m
a = 9*4 = 36m^2
You can also use the rectangle property here.
a = l*b
l = 9
b = 6
a = 9*6 = 54 m^2
Though I would prefer the first one better.
16. Area of triangle = 1/2*bh
b = 17m
h = 3
a = 17*3/2 = 51/2 = 25.5m^2
18. Area of a trapezium = a+b/2*h (a and b are two parallel sides and h the height)
a = 15
b = 7
h = 15
a = 15+7/2*15 = 22/2*15 = 11*15 = 165m^2
19. Area of triangle = 1/2*bh
b = 24
h = 7
a = 24*7/2 = 168/2 = 84
Hope u understood
