Set equal to eachother
(2x+1) = 79
Subtract 1 from both sides
2x=78
Divide 2 from both sides
2x/2=78/2
X= 39

the door frame has measurements of 3 feet by 8 feet. What is the length of the largest table that can be brought in the house on

saw5 [17]

Answer:

sqrt(73) = 8.54 feet.

Step-by-step explanation:

Remark

My guess is without the legs.

The person bringing it in will not be able to get a table in that is longer than the hypotenuse of a right triangle.

Givens

a = 8

b = 3

c = ??

Formula

a^2 + b^2 = c^2

Solution

8^2 + 3^2= c^2

64 + 9 = c^2

c^2 = 73

c = sqrt(73)

c = 8.54

The table can be no longer than 8 feet 5 inches about.

A slug takes 4.25 minutes to travel 11.2 centimeters. What is the speed of the slug in meters per second?

MAXImum [283]

Answer:

$4.39*10^{-4}\ m/sec$

Step-by-step explanation:

Remember that

$1\ m=100\ cm$

$1\ min=60\ sec$

The speed is equal to divide the distance by the time

Convert the units

$4.25\ min=4.25(60)=255\ sec$

$11.2\ cm=11.2/100=0.112\ m$

$0.112/255=0.000439\ m/sec$

$4.39*10^{-4}\ m/sec$
