You could roll a 6-sided die 3 times to simulate this. This is a good simulation because it has one side for each possible tool, and each roll is independent, just as selecting the tool with replacement would be.

Mice21 [21]

Solution: The solution is shown is below figure.

Explanation:

From the given information JKLM is a parallelogram and $\underset{LN}{\rightarrow}$ bisects $\angle KLP$ . So Blank 1 is filled by Given and blank 2 is filled by $\underset{LN}{\rightarrow}$ bisects $\angle KLP$ .

Parallelogram is a quadrilateral whose opposite sides are equal or parallel. Since it is given that JKLM is a parallelogram, therefore the side JM is parallel to the side KL. So blank 3 filled by Definition of parallelogram.

If a line bisects an angle it is means it divides the angle in two equal parts. Since $\underset{LN}{\rightarrow}$ bisects $\angle KLP$ , therefore $\angle 2\cong \angle 3$ . Hence the blank 4 is filled by Definition of bisect.

The transitive property of congruence states that if $\angle 1\cong \angle 2$ and $\angle 2\cong \angle 3$ , then $\angle 1\cong \angle 3$ . Thus, the blank 5 is filled by Transitive Property of Congruence.

iragen [17]

Given that,

Alonzo is $120 in debt. He makes $15 per hour. He wants to have at least $75 left over after he has paid off his debt.

To find,

The inequality and the solution.

Solution,

Let he make $x per hour. Here, $120 is fixed. $15 is added per hour.

ATQ,

$120 + 15x\ge 75$

For atleast, we use $\ge$ .

Subtract 120 from both sides.

$120 + 15x-120\ge 75-120\\\\15x\ge -45\\\\x\ge -3$

So, the required answer is greater than -3.
