Answer:

C) (14, 8, 10)

Step-by-step explanation:

the values in the parentheses go in order of the letters in the first equation

all you have to do is plug in the values

p+q+r=32. (14)+(8)+(10)=32

p-r=4. (14)-(10)=4

2p+q=36. 2(14)+(8)=36

Answer:

The length of the fence needed to surround this garden is $188\ m$

Step-by-step explanation:

Let

x----> the length of the rectangular fence

y----> the width of the rectangular fence

we know that the area of the rectangular fence is equal to

$A=xy$

$A=2,184\ m^{2}$

$2,184=xy$ -----> equation A

we have

$x=10+y$ -----> equation B

Substitute equation B in equation A

$2,184=(10+y)y$

$y^{2}+10y-2,184=0$

using a graphing tool

solve the quadratic equation

The solution is $y=42\ m$

see the attached figure

Find the value of x

$x=10+y$ ----> $x=10+42=52\ m$

Find the perimeter of the rectangular fence

The perimeter is equal to

$P=2(x+y)$

substitute the values

$P=2(52+42)=188\ m$

Thomas went for a long hike and burned 657 calories in 2 1/2 hours. Marvin decided to go for a bike ride and burned 1,035 calori

SVEN [57.7K]

Answer:Marvin burned more calories per hour.

Step-by-step explanation:

Thomas went for a long hike and burned 657 calories in 2 1/2 hours. Converting 2 1/2 hours to improper fraction, it becomes 5/2 hours

This means that the amount of calories that Thomas burnt in 1 hour would be 657 × 2/5 = 262.8 calories per hour

Marvin decided to go for a bike ride and burned 1,035 calories in 3 1/4 hours. Converting 3 1/4 hours to improper fraction, it becomes 13/4 hours

This means that the amount of calories that Thomas burnt in 1 hour would be 1035 × 13/4 = 3363.75 calories per hour

Therefore, Marvin burns more calories per hour.
