Arectangle has a width of 4 centimeters and a perimeter of 26 centimeters. find the length.

length = 9 cm

Step-by-step explanation:

perimeter = p =26 cm

width = w=  4 cm

perimeter of a rectangle= 2*w+2*L

L= length

so we have:

26 = 2*(4) +2*L

26= 8 +2L

26-8 = 2L

18 = 2L

L= 18/2

L =9 cm = length

Length would be 9 centimeters.

Step-by-step explanation:

A rectangle has a width of 4 centimeters and a perimeter of 26 centimeters.

Perimeter = 2(Length + Width)

Let the length of the rectangle be 'L'

2(L + 4) = 26

2L + 8 = 26

2L = 26 - 8

2L = 18

L = 18/2

L = 9

Length would be 9 centimeters.

48 / 6 = x

in this case, x will equal the amount of money in each card!

x therefore will be 8.

trent had $8 in each birthday card.

1,407.5 hours

step-by-step explanation:

we first convert all the time to hours and then sum them up.

there are 24 hours in 1 day, in 58 days, there are 24 x 58 = 1,392 hours.

there are 60 minutes in 1 hour, thus, 30 minutes will be equivalent to 30 / 60 = 0.5 hours.

therefore, the number of hours it will take mercury to complete a full rotation is 1,392 + 15 + 0.5 = 1,407.5 hours
