Amanda needs to spend more than 8 minutes on Routine 1 to burn more calories.
Step-by-step explanation:
Given,
Calories burned in Routine 1 = 15.5 calories per minute
Let,
t represents the number of minutes spent running.
Total calories burned = T
T = 15.5t Eqn 1
Calories burned in Routine 2 = 22 calories walking + 12.75 per minute
T = 12.75t + 22 Eqn 2
For burning more calories in Routine 1;
Eqn 1 > Eqn 2
Dividing both sides by 2.75
Amanda needs to spend more than 8 minutes on Routine 1 to burn more calories.

Answer:
a = √10
Step-by-step explanation:
a² + b² = c²
a² + 9² = (√91)²
a² + 81 = 91
a² = 10
a = √10
hope this helps :)
a) T = 4K / M
1) multiply both sides by M => TM = 4K
2) divide both sides by 4 => K = TM / 4
Answer: K = TM / 4
b) bm - Kn = 14
1) add Kn to both sides => bm = 14 + Kn
2) subtract 14 from both sides => bm - 14 = Kn
3) divide both terms by n => K = [bm - 14] / n
Answer: K = [bm - 14] / n
Answer:
<h3>Options "
Consecutive angles are supplementary" and "
Only two opposite sides are parallel" are correct</h3>
Step-by-step explanation:
<h3>The property of Trapezoids are</h3>
- The bases are parallel by definition.
- Each lower base and upper base angles are supplementary on the same side.
From the property 1 we have that the bases (that is base of trapezoid or opposite sides ) are parallel.And by property 2 we have that each lower and upper base angles are supplementary on the same side
Therefore the options Consecutive angles are supplementary and Only two opposite sides are parallel are correct
