Answer: 24.7
cos 54° = x/42
⇔ x = 42. cos 54°
⇔ x ≈ 24.7
Step-by-step explanation:
Answer:
32
Step-by-step explanation:
Answer:
Step-by-step explanation: The earth rotates 34 km every 32 seconds. We can simplify this by dividing both sides by 32. Now, we have 34/32 km every 32 seconds. Now, to further simplify this, we need to convert 34/32 to a mixed number 34/32 = 1 2/32 which then can be simplified to 1 1/16. So, near the equator, the speed of Earth's rotation is 1 1/16 km per second.
Answer:
Diagonal
Step-by-step explanation:
The measure of a television is always indicated by providing the length of the diagonal, in inches.
In fact, the actual length and height of a 32" tv are:
- Length:
L = 27.9 inches
- Height:
h = 15.7 inches
For an object with a rectangular shape, such as the TV, the diagonal of the object can be found by using Pythagorean's theorem:

where
L is the length of the rectangle
h is the height of the rectangle
Substituting the values above, we find:

Which corresponds to the diagonal of the TV.
Answer: C- 17 hrs /2 weeks
Step-by-step explanation:
Write the number of hours in the numerator and the number of weeks in the denominator.
68 hrs/8 weeks
Simplify by dividing 4 into both the numerator and denominator.
68/8 = 17/2
