Students volunteering at a charity event work 1/2- hour shifts. zack volunteered for 4 hours. he incorrectly divided one half by four to find the number of shifts he worked. how should zack have calculated the number of his shifts

He should have divided 4 by  :

Step-by-step explanation:

You know that the students work -hour shifts at the charity event and Zack worked in the event for four hours.

Then, to calculate the number of shifts he worked, he should not have divided by 4. He should have divided 4 by  .

Let's make the correct procedure to calculate the number of shifts Zack worked  at the charity event. This is:

Therefore, he worked 8 shifts.

d (5 x (-20)) * (100 x (0.7))

step-by-step explanation:

5÷1/100 * -.7 *-20

copy dot flip

5*100 * -.7 *-20

rearrange

5*-20   * 100 *-.7

-100   *-70

7000

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
