The cosine of the angle the refrigerator makes with the floor is option (E) 3/5 is the correct answer.
What is trigonometry?Trigonometry is mainly concerned with specific functions of angles and their application to calculations. Trigonometry deals with the study of the relationship between the sides of a triangle (right-angled triangle) and its angles.
For the given situation,
Harold tilted the 5 foot fridge, so the slanting height = 5 feet
The tilted refrigerator makes the height 4 feet from the floor.
From the diagram,
The three sides of the triangle according to Pythagoras theorem are
Hypotenuse side, h = 5 feet
Opposite side, o = 4 feet
Let a be the adjacent side.
By Pythagoras theorem,
[tex]Hypotenuse^{2} = Opposite^{2}+Adjacent^{2}[/tex]
⇒ [tex]5^{2} =4^{2} +a^{2}[/tex]
⇒ [tex]a^{2} = 25-16[/tex]
⇒ [tex]a=\sqrt{9}[/tex]
⇒ [tex]a=3[/tex]
Thus the trigonometric ratio cosine of the angle is
[tex]cos \theta =\frac{Adjacent}{Hypotenuse}[/tex]
⇒ [tex]cos \theta =\frac{3}{5}[/tex]
Hence we can conclude that the cosine of the angle the refrigerator makes with the floor is option (E) 3/5 is the correct answer.

The figure is made up of two cones and a cylinder. Both cones and the cylinder have a 10 mm diameter. What is the exact volume of this figure? What is the volume of this figure? A.250(pi)mm³
B.4007(pi)mm³
C.6257(pi)mm³
D.2500(pi)mm³
Answer:
Step-by-step explanation:
The answer choices don’t make sense. The volume of a cylinder of height 45mm and radius 5mm = π5²*45 = 1125π mm³.
Three of the answer choices are larger than 1125π.
:::::
volume of one cone = πr²h* ⅓
Volume of cylinder section = πr²h
Total volume = πr²h*⅔ + πr²h = πr²h*5/3 = π5²*15*5/3 = 625π

Ethen is ‘x’ years old. Raj is 8 years older than Ethen. Find the sum of their ages in 6 years time.
Answer:
2x+20
Step-by-step explanation:
Given
Age of Ethen = x
If Raj is 8 years older than Ethen, then;
Raj = x + 8
6 years time
Ethen age = x+ 6
Raj = x+8+6 = x+14
Sum of ages in 6 years time = x+6+x+14
Sum of ages in 6 years time = 2x + 20
Hence the required sum of ages is 2x+20

Answer:
r ≥ -49/11
Simplified versions: r ≥ -4.45 or r ≥ -4 5/11
Answer: [tex]r \ge -\frac{49}{11}[/tex]
r is greater than or equal to the fraction -49/11
==========================================================
Work Shown:
[tex]r + 5(-2r-10) \le -4r - 1 + 6r\\\\r - 10r - 50 \le -4r - 1 + 6r\\\\-9r - 50 \le 2r - 1\\\\-9r-2r \le - 1 + 50\\\\-11r \le 49\\\\r \ge \frac{49}{-11}\\\\r \ge -\frac{49}{11}\\\\[/tex]
Note how the inequality sign flips. This happens any time you divide both sides by a negative number.
