frankie calculated that she would need 9.5 yards of wallpaper to decorate her room. The wallpaper she chose had a large pattern, so instead she needed 13 yards of that paper. What is the percent of increase, rounded to the nearest percent, in the amount of wallpaper she need? Show your work.

The percent of the increase in the amount of wallpaper is 37% to the nearest percent

Step-by-step explanation:

The percentage of increase = [(New - original) ÷ original] × 100%

∵ Frankie would need 9.5 yards of wallpaper to decorate her room

∴ The original value = 9.5 yards

∵ The wallpaper she chose had a large pattern, so instead she

   needed 13 yards of that paper

∴ The new value = 13 yards

→ By using the rule above

∵ Percent of increase = × 100%

∴ Percent of increase = × 100%

∴ Percent of increase = 0.36842105 × 100%

∴ Percent of increase = 36.842105%

→ Round it to the nearest percent (whole number)

∴ Percent of increase = 37%

The percent of the increase in the amount of wallpaper is 37% to the nearest percent

i do not know this sorry : (

the system of inequity is

step-by-step explanation:

from the given graph it is noticed that we have two related lines. one is solid and another is dashed.

if a line passing through two points, then the equation of line is

the solid line passing through the points (0,4) and (4,0).

the related equation of solid line is .

similarly, find the related equation of dashed line. the dashed liune passing through the points (0,0) and (3,1).

the related equation of dashed line is

from the given graph it is noticed that the point (0,1) lies on the shaded region, therefore the point (0,1) must be satisfied by the related equations.

check the related equations by the point (0,1).

this statement is true if the sign of inequality is < instead of equality. since it is an solid line therefore the sign of inequality will be . the required inequality is

similarly, check the second related equation.

it is a dashed line, so this statement is true if the sign of inequality is > . the required inequality is
