Answer:

8,7

Step-by-step explanation:

Add both "x" coordinates, divide by 2.

Add both "y" coordinates, divide by 2.

so x1+x2/2 and y1+y2/2

so 5,8 and 11,6 5+11=16 and then 16/2=8

then take your cords from y axis so 8+6=14 and then 14/2=7

Is 2 and 4.5 equivalent ​
o-na [289]

2 and 4.5 is not equivilant since 2 and 4.5 cannot go together (the 0.5 does not help and so it does not make it equivalent.)

Hope this helped!

Answer:

G

Step-by-step explanation:

Red marble probably currently: 12/32 = 3/8

Guess and check (using the multiple choice answers):

F: 12 + 13 / 32 + 13 = 25/45 = 5/6; does not equal 3/5

G: 12 + 18 / 32 + 18 = 30/50 = 3/5; does equal 3/5

H: 12 + 28 / 32 + 28 = 40/60 = 2/3; does not equal 3/5

J: 12 + 32 / 32 + 32 = 44/64 = 11/16; does not equal 3/5

K: 12 + 40 / 32 + 40 = 52/72 = 13/18; does not equal 3/5

Which area of the rectangle is correct?
Goshia [24]

Answer:

55/96

Step-by-step explanation:

To find the area, we need to multiply <em>l x w</em>

<em>Take the length 11/12 and the width 5/8 and multiply - </em>

11 times 5 = 55

12 times 8 = 96

<em>Answer:</em> 55/96

Evaluate -6+(-12) =(-6).
padilas [110]

Cancelling out both the -6 we get 12=0 which is not true, hence the equation is incorrect.

If a room temperature roast cools from 68°F to 25°F in 5 hours at freezer temperature of 20°F,
Deffense [45]

Answer:

9 hours

Step-by-step explanation:

According to Newton's laws of cooling

dT/dt = -k(T - A)

Let U = T - A

dU/dT = 1

dU = dT

dt/dt = -kU

dT = -kU(dt)

dU/U = -kdt

On integration

ln(U) = -kt + C

U = Ce^-kt

T - A = Ce^-kt

T(0) = 68

T(5) = 25

68 - 20 = Ce^-k(0)

C = 48

and

25 -20 = 48e^-k(5)

5 = 48e^-5k

e^-5k = 5/48

-5k = ln (5/48)

k = - ln(5/48) / 5

k = - 0.4524

T - 20 = 48e^-0.4524t

When T = 21

21 -20 = 48e^-0.4524t

1 = 48e^-0..4524t

e^-0.4524t = 1/48

-0.4524t = ln (1/48)

t = - ln(1/48) / 0.4524

t = 8.5570

t= 9 hours ( to the nearest hour)
