Please help I’m stuck on the last one

AB = 14.0 cm

Step-by-step explanation:

Pythagora's Theorem

In a right triangle with a hypotenuse of length H and legs of lengths L and W, then it's satisfied the equation:

The diagram shows a wedge ABCDEF and it's required to calculate the length of the side AB.

Note the triangle FCB is right at C, where side length is the hypotenuse:

Triangle ABF is right at B and 20 cm is the hypotenuse, thus:

Solving for AB:

AB = 14.0 cm

a) 0.25x times 3. (could be wrong on equation.)

b) 2.25 pound of dark chocolate. (can i eat all the chocolate? plz? anyway, again, could be wrong, but i hope im right. all the chocolate together should be 5.25 pounds)

have a good day!

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
