Answer:

P = 24.135 pounds per square inch

Step-by-step explanation:

The air pressure in the tire should be 24\dfrac{27}{200} pounds per square inch. This pressure is in the form of a mixed fraction. It is required to convert this pressure into a decimal form. We can convert it as follows :

24\dfrac{27}{200}=\dfrac{(24\times 200)+27}{200}\\\\=24.135\ \text{pounds/square inch}

In decimal form, the value of pressure in the tire on the digital pressure gauge is 24.135 pounds per square inch.

PLEASE! An item costs 410 before tax, and the sales tax is 32.80.
Norma-Jean [14]

Divide the amount of the tax by the cost of the item:

32.80 / 410 = 0.08

Multiply by 100:

0.08 x 100 = 8%

Answer: 8%

100 points!! Brainliest if correct!!

surface area (S) of a right rectangular solid is:

S = 2*L*W + 2*L*H + 2*W*H (equation 1)

where:

L = length

W = width

H = height

-----

you have:

L = 7

W = a

H = 4

-----

formula becomes:

S = 2*7*a + 2*7*4 + 2*a*4

simplify:

S = 14*a + 56 + 8*a

combine like terms:

S = 22*a + 56

-----

answer is:

S = 22*a + 56 (equation 2)

-----

to prove, substitute any value for a in equation 2:

let a = 15

S = 22*a + 56 (equation 2)

S = 22*15 + 56

S = 330 + 56

S = 386

-----

since a = 15, then W = 15 because W = a

go back to equation 1 and substitute 15 for W:

S = 2*L*W + 2*L*H + 2*W*H (equation 1)

where:

L = length

W = width

H = height

-----

you have:

L = 7

W = 15

H = 4

-----

equation 1 becomes:

S = 2*7*15 + 2*7*4 + 2*15*4

perform indicated operations:

S = 210 + 56 + 120

S = 386

-----

surface area is the same using both equations so:

equations are good.

formula for surface area of right rectangle in terms of a is:

S = 22*a + 56

-----
