A hotel has 480 rooms. Of these rooms,
are non-smoking. How many rooms are smoking?
Answer:
The number of smoking rooms [tex]N_s = \frac{480(100-x)}{100}[/tex], in which x is the percentage of non-smoking rooms.
Step-by-step explanation:
We are given a percentage of rooms that are non smoking, lets say x%, and (100-x)% will be smoking rooms. The number of rooms which are smoking is the total number of 480, multiplied by (100-x) and divided by 100.
Then:
[tex]N_s = \frac{480(100-x)}{100}[/tex]

Which of these points is on circle with a center at (0, 0) that includes the point (-1, -3)?
¿Cuál de los siguientes puntos está en el círculo con centro en (0,0) y incluye el punto (-1.-3)?
A. (0, 10)
B. (10, 10)
C (V10,0)
D(V10,10
Answer:(0,10)
Step-by-step explanation:
The points On circle with a center at (0, 0) that includes the point (-1, -3) would be (0, 10).
What is the equation of the circle with radius r units, centered at (x,y) ?If a circle O has a radius of r units length and that it has got its center positioned at (h, k) point of the coordinate plane,
then, its equation is given as:
[tex](x-h)^2 + (y-k)^2 = r^2[/tex]
We have given On circle with a center at (0, 0) that includes the point (-1, -3).
So the equation form
[tex](x-h)^2 + (y-k)^2 = r^2[/tex]
[tex](x-0)^2 + (y-0)^2 = r^2\\\\x^{2} +y^{2} =r^{2} \\\\(-1)^{2} +(-3)^{2} =r^{2} \\\\r^{2} = 10[/tex]
So, the other point that satisfies the equation would be (0, 10).

Step-by-step explanation:
Only two sides are marked as congruent. So, any claim using SSS is automatically false. (SSS requires 3 corresponding sides be congruent.)
Of the claims citing SAS, the one regarding ΔABD is false. The points A, B, and D are on the same line, so do not form a triangle.

if there consecutive terms of an AP are k+2 ,4k -6 and 3k-2 . What is the value of k
===========================================================
Explanation:
A = first term = k+2B = second term = 4k-6C = third term = 3k-2To go from the first term to the second term, we add on some common difference d.
So,
B = A+d
B = (k+2)+d
4k-6 = k+2+d
4k-6-k-2 = d
d = 3k-8
---------------
Similarly, to go from the second term to the third term, we also add on d
C = B+d
C = (4k-6)+d
C = (4k-6)+(3k-8)
C = 7k-14
3k-2 = 7k-14
---------------
Let's solve for k
3k-2 = 7k-14
-2+14 = 7k-3k
12 = 4k
4k = 12
k = 12/4
k = 3 is the final answer
---------------
If k = 3, then we have these three terms:
A = k+2 = 3+2 = 5B = 4k-6 = 4(3)-6 = 6C = 3k-2 = 3(3)-2 = 7The arithmetic progression (AP) is 5, 6, 7. The common difference is d = 1.
Note how d = 3k-8 = 3(3)-8 = 1
A cylindrical shoe polish tin is 10cm in diameter and 3.5cm deep
calculate the capacity of the tin in cm^3
Answer: 274.75
Step-by-step explanation:
To find the volume of a cylinder you find the area of the base and then multiply it by the height. The base is the radius (half the diameter) squared times pi which we will use 3.14. That gets us 78.5. Then we multiply by the height to get 274.75!
Hope this helps!
The capacity/volume of the cylinder is approximately: 274.89 cm³
What is the Capacity of a Cylinder?capacity of a cylinder = volume of cylinder = πr²h.
Given the following:
Radius (r) = 10/2 = 5 cmHeight (h) = 3.5 cmCapacity/Volume of the cylinder = π(5²)(3.5)
Capacity/Volume of the cylinder ≈ 274.89 cm³

Solve for the value of X. Round to the nearest whole number.
Answer:
x = 30º
Step-by-step explanation:
This answer requires trigonometry, specifically, the cosine function. This is because we are given the length of the side adjacent to x and the length of the hypotenuse.
If you recall:
[tex]cos(x )= \frac{adjacent}{hypotenuse}[/tex]
Therefore,
[tex]cos(x) = \frac{13}{35}[/tex]
Now, we must use the inverse cosine function on a calculator to figure out the value of x.
[tex]cos^{-1}(\frac{13}{15}) = 29.93[/tex]
Now, we must round it to the nearest whole number, so x = 30º.

A bag with 6 marbles is shown below. (3 marbles are red, 1 is yellow, and 2 are blue.) A marble is chosen from the bag at random. What is the
probability that it is red?
Write your answer as a fraction or a whole number.
Answer:The answer is 1/2 or you can do 3/6 if it doesnt need to be simplified
Step-by-step explanation:
Probability is the chance of an event to occur from a number of possible outcomes.
The probability that a marble chosen at random is red is 1/2.
What is probability?It is the chance of an event to occur from a number of possible outcomes.
It is given by:
Probability = Number of required events / Total number of outcomes
We have,
Total number of marbles in the bag = 6
Number of red marbles = 3
Number of yellow marbles = 1
The number of blue marbles = 2
The probability that a marble chooses is red:
= Number of red marbles / total number of marbles
= 3 / 6
= 1 / 2
Thus,
The probability that a marble chosen at random is red is 1/2.
