Jessica has $50 to buy a jacket and a hat in the store. Ajacket costs $39 08 and a hat costs $12.55. Jessica says she stays within the budget. Is she
correct? Explain
00:00
Jessica is correct. $39.08 rounds to $30 and $12.55 rounds to $20, and $30 + $20 = $50

Jessica is correct. $39.08 + $12.55 = $51.63, which is less than $50.
► 00:00
Jessica is correct. $39.08 rounds to $40 and $12.55 rounds to $10, and $10+ $40 = $50
► 00:00
Jessica is incorrect. $39.08 + $12.55 = $51.63, which is greater than $50.

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

arc length = 6.63311 ft.

step-by-step explanation:

the formula the arc measure is:

arc length s=2πr(c)/360

where:

c   is the central angle of the arc in degrees

r   is the radius of the arc

π   is pi, approximately 3.142

using the above formula we get

s =

thus we find that arc length of an arc for a circle of radius 20 feet and central angle 19 degrees is

6.63311 feet
