An equation to model the situation is 18+2x=24 and the width of the border is 3 inches

Step-by-step explanation:

Given :A painting is 18 inches wide. It is placed inside a frame with a border that is x inches wide.

The total width of the painting and the frame is 24 inches.

To Find : Create an equation to model the situation, and then solve the equation to find the width of the border.

Solution :

Width of painting = 18 inches

It is placed inside a frame with a border that is x inches wide. (from 1 side)

So, Total width of painting +frame = 18+2x

We are given that The total width of the painting and the frame is 24 inches.

So, equation becomes : 18+2x=24

18+2x=24

2x=6

x=3

Hence an equation to model the situation is 18+2x=24 and the width of the border is 3 inches

yes the total will be same because in both of them the expression.is rearranged but their sign remains the same hence it hss just been shuffled

i found the life tables for the year 2012.

life table of males at age 30. probability of dying between ages x and x+1

total population:

29–30 . . . . . . . . . . . . 0.001030

30–31 . . . . . . . . . . . . 0.001061

males:

29–30 . . . . . . . . . . . . 0.001420

30–31 . . . . . . . . . . . . 0.001448

white population

29–30 . . . . . . . . . . . . 0.001005

30–31 . . . . . . . . . . . . 0.001037

white males

29–30 . . . . . . . . . . . . 0.001372

30–31 . . . . . . . . . . . . 0.001399

non hispanic white population

29–30 . . . . . . . . . . . . 0.001083

30–31 . . . . . . . . . . . . 0.001116

non hispanic white males

29–30 . . . . . . . . . . . . 0.001477

30–31 . . . . . . . . . . . . 0.001503

jacob, non hispanic white male. 30 years old.

probability that jacob lives to be 30 years old.

since the given probabilities are probabilities of dying, i think we simply subtract it from 1 to get the probability of living. we will use the probability of non hispanic white male.

probability of living to be 30 y.o.

29 - 30 : 1 - 0.001477 = 0.998523

30 - 31 : 1 - 0.001503 = 0.998497

Abucket of paint has spilled on a tile floor. the paint flow can be expressed with the function p(t) = 6(t), where t represents time in minutes and p represents how far the paint is spreading. the flowing paint is creating a circular pattern on the tile. the area of the pattern can be expressed as a(p) = 3.14(p)^2 part a: find the area of the circle of spilled paint as a function of time, or a[p(t)]. show your work. part b: how large is the area of spilled paint after 8 minutes? you may use 3.14 to approximate pi in this problem.
