Help please time limit...Amanda is choosing between two exercise routines.
Marina86 [1]

Amanda must spend more than 8 minutes on Routine #1 to burn more calories than Routine #2.

Step-by-step explanation:

Routine # 1;

Calories burned in running = 15.5 per minute

Let,

t be the minutes spent running.

T = total calories burned

T = 15.5t

Routine # 2;

Calories burned while walking = 22 calories

Calories burned while running = 12.75 per minute

T = 12.75t + 22

For burning more calories in Routine 1;

Routine 1 > Routine 2

15.5t>12.75t+22\\15.5t-12.75t>22\\2.75t>22\\

Dividing both sides by 2.75

\frac{2.75t}{2.75}>\frac{22}{2.75}\\t>8

Amanda must spend more than 8 minutes on Routine #1 to burn more calories than Routine #2.

saveliy_v [14]

Answer:

<em>Answer is</em><em> </em><em>330</em>

Step-by-step explanation:

area \: of \: shaded \: region \:  = \pi {r}^{2}  - \pi( {x}^{2}  \\ here \: r = 11 \: cm \: and \: x = 4 \: cm \\ area \: of \: a \\ shaded \: regoin \:  = \pi( {r}^{2} -   {x}^{2} ) \\  = \pi( {11}^{2}  -  {4}^{2} ) \\  = \pi(121 - 16) \\  = \pi(105) \\  =  \frac{22}{7}  \times 105 \\  = 22 \times 15 \\  = 330  \: {cm}^{2}

<em>AREA</em><em> </em><em>OF</em><em> </em><em>SHADED</em><em> </em><em>REGION</em><em> </em><em>=</em><em>330</em>

<em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em>HAVE A NICE DAY</em><em>!</em>
