20% of what number is 36?
Provide an exact fraction answer. (Mixed fraction) please show how you got your answer ;) Thank you in advance
Answer:
180
Step-by-step explanation:
180 * .2 = 36
20% is the same thing as 1/5 of something, so read the question again,
"36 is 1/5 of what number?"
Multiply 36 by 5 to get 180
Double check yourself by finding 20% of 180
180 * .2 = 36
Hope this helped, queen!

A grocery store sells 6 bottles of water for $4 and 18 bottles for $10. Is the cost of the water proportional to the number sold?
Proportional
Nonproportional
Answer:
Non Proportional
Step-by-step explanation:
Make a proportion:
For example say you want to test out how many bottles of water you can buy for $10
Proportion:
4 - 6
10 - ?
Solve: 10×6÷4=15
So technically, you could only get 15 bottles for $10. Therefore, this is a non proportional problem.
Consider the 4th roots of 16[cos(π) + i sin(π)].
The roots are located on a circle with center at the origin and radius of ....
The arguments of two successive roots differ by.... π units along the circumference of a circle.
Answer:
2 1/2
Step-by-step explanation:
The roots are located on a circle with a center at the origin and a radius of 4. The arguments of two successive roots differ by (1/2)π units along the circumference of a circle.
What is the Circumference of a circle?The circumference of a circle is defined as the product of the diameter of the circle and pi.
The 4th roots of 16[cos(π) + i sin(π)] are the 4th roots of -16i. These roots are located on a circle with a center at the origin and a radius of 4 because the 4th roots of a complex number are equally spaced on a circle with a radius equal to the absolute value of the complex number.
The arguments of two successive roots differ by π/2 units along the circumference of a circle. This is because there are 4 roots and the circle has a circumference of 2π, so each root is spaced 2π/4 = π/2 units apart along the circumference of the circle.
For example, the first root is located at (4, 0) on the complex plane, which corresponds to an argument of 0.
The second root is located at (0, 4) on the complex plane, which corresponds to an argument of π/2.
The third root is located at (-4, 0) on the complex plane, which corresponds to an argument of π.
The fourth root is located at (0, -4) on the complex plane, which corresponds to an argument of 3π/2.
Thus, you can see that the arguments of the roots differ by π/2 units.

Caterer A charges $15 per person and $100 to set up tables. Caterer B charges $20 per person and $50 to set up tables.
For what number of guests will the cost of Caterer A be the same as the cost of Caterer B? number or guest
Answer:
Number of guests = 10
Step-by-step explanation:
Given that:
Caterer A charges $15 per person and $100 to set up tables. Caterer B charges $20 per person and $50 to set up tables.
Let,
x be the number of guests.
A(x) = 15x + 100
B(x) = 20x + 50
For the cost to be equal;
A(x) = B(x)
15x + 100 = 20x + 50
100 - 50 = 20x - 15x
50 = 5x
Dividing both sides by 5
[tex]\frac{5x}{5}=\frac{50}{5}\\x=10[/tex]
Hence,
Number of guests = 10

Answer:
41.7 nautical miles
Step-by-step explanation:
It can help to draw yourself a diagram. It will show you the desired distance is the hypotenuse of a right triangle with side lengths 36 and 21. The Pythagorean theorem can be used to find the distance of interest.
d² = 36² +21²
d² = 1296 +441 = 1737
d = √1737 ≈ 41.6773

Given: in a right triangle, cot0 = 28/45
1. what is csc0
2. what is sec0
Answer:
i) [tex]cosec0 = \frac{hypotenuse}{opposite side} = \frac{53}{45}[/tex]
ii) [tex]sec0 = \frac{hypotenuse}{adjacent side} = \frac{53}{28}[/tex]
Step-by-step explanation:
Step(i):-
Given that
[tex]cot 0 = \frac{28}{45} = \frac{adjacentside}{opposite side}[/tex]
Hypotenuse AC² = AB²+BC²
⇒ AC² = 45²+28² = 2809
⇒ AC = √2809
⇒ AC = 53
Hypotenuse AC =53
Step(ii):-
i) [tex]cosec0 = \frac{hypotenuse}{opposite side} = \frac{53}{45}[/tex]
ii) [tex]sec0 = \frac{hypotenuse}{adjacent side} = \frac{53}{28}[/tex]
