The right answer is Option A.
Step-by-step explanation:
Given,
Heart rate goal = I
Heart rate reserve = H
70% of H = 
Resting heart rate = R
According to given statement,
70% of heart rate reserved is added to resting heart rate to calculate heart rate goal, therefore,
I = R + 0.7H
I=R+0.7H represents the given situation.
The right answer is Option A.

12 + 6 = 18 units.... takes 12 units to go to (0,0) then 6 more units to go to (6,0)
Answer:
Step-by-step explanation:
Use Pythagorean Theorem: a^2+b^2=c^2 (a squared plus b squared equals c squared), where a and b are legs from the 90 degree angle and c is the opposite side of the triangle.
So for part a: a=AB=30 b=AC=30 and c=BC
a^2 +b^2 = c^2 Plug in the knowns
30^2 +30^2=c^2 Use Pemdas, Exponents first.
30^2=900 Simplify the equation
900+900=c^2 Simplify again
1800=c^2 Now to get rid of the ^2 we need to know the square root of 1800.
It is 42.426406871.........(There are more numbers in the decimal. Choose your stopping point and round) I'm going to round to the hundredths.
So, the answer to part a is 42.43 kilometers.
Now for part b. a=AD=45 b=AB=30 c=DB
Same equation
a^2 + b^2 =c^2 Plug in the knowns
45^2 + 30^2 =c^2 Simplify
2025 + 900 =c^2 Simplify
2925 =c^2 Find the square root
54.3083269 Round to the decimal place needed. I'm going with Hundredths.
Part b answer is 54.31 kilometers.
Answer:
A. 300π units³
Step-by-step explanation:
Formula for volume of a cone = ⅓πr²h
Where,
radius (r) = ½(10) = 5 units
height (h) = 36 units
Plug in the values and find the volume in terms of π
Volume of the cone = ⅓*π*5²*36
Volume of the cone = 300π units³
