Carleen Bailey works at a boutique eight hours a day, earning $9.48 an hour. She is asked to work two additional hours at time and a half to help prepare for an incoming shipment. How much will she earn for these two hours of overtime?

Answers

Answer:

The correct answer is $23.70.

Step-by-step explanation:

9.48 times 2.5 is 23.7

Final answer:

Carleen Bailey would earn $28.44 for the two hours of overtime she worked. She earns 1.5 times her normal hourly wage for overtime hours.

Explanation:

Carleen Bailey earns $9.48 for each regular hour she works. When she works overtime, she earns 1.5 times her normal rate for each additional hour. That means her overtime rate is $9.48 * 1.5 = $14.22 per hour. Therefore, if she works 2 hours of overtime, she will earn $14.22 * 2 = $28.44 in total for the overtime hours.

Round 3 3/8 to the nearest whole number.

Answers

The round off will be 3nearestwhole number.

What is Rounding Numbers?

Rounding a number means the process of making a number simpler such that its value remains close to what it was. The result obtained after rounding off a number is lessaccurate, but easier to use. While rounding a number, we consider the place value of digits in a number.

There are some basic rules that need to be followed for rounding numbers.

  • We first need to know what our rounding digit is. This digit is the one that will ultimately be affected.
  • After this, we need to check the digit to the right of this place which will decide the fate of the rounding digit.
  • If the digit to the right is less than 5, we do not change the rounding digit. However, all the digits to the right of the rounding digit are changed to 0.
  • If the digit to the right is 5 or more than 5, we increase the rounding digit by 1, and all the digits to the right of the rounding digit are changed to 0.

Given:

3 3/8

Solving the mixedfraction

= 27/8

=3.375

= 3 ( nearest whole number)

Now, to round off nearest whole number will be 3

What is the least amount of acute angles a triangle can have?
According to the given information, quadrilateral RECT is a rectangle. By the definition of a rectangle, all four angles measure 90°. Segment ER is parallel to segment CT and ______________ by the Converse of the Same-Side Interior Angles Theorem. Quadrilateral RECT is then a parallelogram by definition of a parallelogram. Now, construct diagonals ET and CR. Because RECT is a parallelogram, opposite sides are congruent. Therefore, one can say that segment ER is congruent to segment CT. Segment TR is congruent to itself by the Reflexive Property of Equality. The Side-Angle-Side (SAS) Theorem says triangle ERT is congruent to triangle CTR. And because corresponding parts of congruent triangles are congruent (CPCTC), diagonals ET and CR are congruent.
