The y axis is the heart rate so for the first one it is 121 then for the x axis which is age it will be 55.For second the heart rate is less than 198 and 90 for age
Answer:
2250m
Step-by-step explanation:
Step 1
Since
Hence,
tan x = 3/4
tan y=5/7
tan x = BA/ CA where BA = height and CA = distance
3/4 = h/ d
4h = 3d
h = 3d/4.......... Equation 1
tan y = BA / DA + 150m
5/7 = h/d + 150
7 × h = 5(d + 150)
7h = 5d + 750............ Equation 2
Since h = 3d/4
7(3d/4) = 5d + 750
21d/4 = 5d + 750
Multiply both sides by 4
21d = 4(5d + 750)
21d = 20d + 3000
21d -20d = 3000
d = 3000
Distance (d) = 3000m
Substitute 3000m for d in equation 1
h = 3d/4
h = 3 × 3000/4
h = 2250m

Step-by-step explanation:
Your question isn't complete but let's assume that you want to know the amount of time that she spends working on her homework.
Since we are informed that Ella practices piano for 45 minutes and that she spends m minutes longer working on her homework than she does practicing the piano, the expression to get the number of minutes that she uses on her homework will be:
= 45 + m
For example let's say that she spends 7 minutes more in her homework. Therefore, the total minutes spent on the homework will be:
= 45 + 7
= 52 minutes
