The minimum target heart rate for a person 20 years old is 120 beats per minute

<h3>How to predict the minimum target heart rate?</h3>

The equation of the function is given as:

y = -0.6x + 132

Where x represents the age, and y represents the minimum target heart rate

From the question, we have:

x = 20

Substitute x = 20 in y = -0.6x + 132

This gives

y = -0.6 *20 + 132

Evaluate

y = 120

Hence, the minimum target heart rate for a person 20 years old is 120 beats per minute

GEOMETRY HELP ASAP I'M FAILING. I did the first half now i cant figure this out!!?
Shalnov [3]
OK, so;
BDE and BED are congruent because the opposite sides are both congruent
To find BDE and BED you must subtract 66 degrees from 180 degrees.
You are then left with 114 as the sum of both the angles you need to find
Since they are congruent, all you need to do is divide by two
114/2=57 degrees for both BDE (a) and BED(b)
Now for angle A and C;
This is easy because they are both congruent to the first two!
So basically, all of question four is "57 degrees"
 Sadly for number 5 i did not understand the question :"(
For 6 tho;
AC is parallel to DE because angle C is congruent to angle BED 
All the others can be ruled out 
For 7;
BD is half the length of AE, so:
 4x+20=2(3x+5)
4x+20=6x+10
20=2x+10
10=2x
x=5
 This means BD is 20 bc
3(5)+5
15+5
20
 And AE is 40 bc
20X2=40
or...
4(5)+20

Please help I will give brainliest to whoever explains step by step
Evgesh-ka [11]

Answer: In the exact order up to down: 80, 74, 110, 96, 80

Step-by-step explanation:

Do the equation

360=(x-6)+(x+30)+1.2x+x

we can simplify by doing

360=(x-6)+(x+30)+2.2x

=360=x-6+x+30+2.2x

=360=4.2x+24

=336=4.2x

=80=x

x=80
