When using scientific notation, you only want one number to be in front of the decimal place. If you have to make the number smaller, then the 10^nth power will be positive. If you have to make the number bigger, then 10^nth power will be negative. Example:
0.54 --> 5.4 * 10^-1
35 --> 3.5 * 10^1
The value of n depends on how many spaces the decimal point needs to be moved. For your question, putting 23 in scientific notation would look like this:
23 --> 2.3 * 10^1

Total hours worked for Hans Zupp is ___ .
storchak [24]

Answer:

Option (D)

Step-by-step explanation:

Total hours worked of Monday= 4:45 hours + 5:00 hours = 9:45 hours

Total hours worked of Tuesday= 4:45 hours + 4:45 hours = 9:30 hours

Total hours worked of Wednesday= 4:30 hours + 4:30 hours = 9:00 hours

Total hours worked of Thursday= 4:45 hours + 4:15 hours = 9:00 hours

Total hours worked of Friday= 4:45 hours + 4:15 hours = 9:00 hours

Total hours worked = 9:45 + 9:30 + 9:00 + 9:00 + 9:00

                                 = 46:15 hours

                                 ≈ 46 hours 15 minutes

Option (D) will be the answer.

In parallelogram WXYZ, with diagonal XZ, m∠WXZ = 81° and m∠WZX = 28°. What is the measure of ∠XYZ?
Lisa [10]

The measure of angle XYZ in the parallelogram is: 71°.

<h3>What are the Opposite Angles of a Parallelogram?</h3>

In a parallelogram, the angles that are opposite each other are congruent.

Find m∠XWZ using the triangle sum theorem:

m∠XWZ = 180 - m∠WXZ - m∠WZX

m∠XWZ = 180 - 81 - 28

m∠XWZ = 71°

m∠XWZ = m∠XYZ [opposite angles are congruent]

m∠XYZ = 71°

Find the length of the third side. If necessary, write in simplest radical form.
Angelina_Jolie [31]

Answer:

the length of the missing side is 2

Step-by-step explanation:

Use a^2 + b^2 = c^2

a = 4

b = ?

c = 2sqrt5

4^2 + b^2 = (2sqrt5)^2

16 + b^2 = 20

subtract 16 from both sides

b^2 = 4

take the sqrt of both sides

b = 2
