Only three are geometric sequences, a which is 3/16, 3/8, 3/4, 3/2, d which is 3,9,27,81 and f which is -4(4/9)^x
What is a geometric sequence?A geometric sequence is a sequence of numbers or functions in which successive member differ by a constant term called the common ratio.
Analysis:
For a, the first term is 3/16, second term is 3/8. if we divide the second term by the first we have 2. If we do same with the third and second we still have 2. so this is a geometric sequence
For d, if we divide 9 by 3 we have 3, if we divide 27 by 9 we have 3. so this is a geometric sequence.
For f, if we make x equal to a nonzero integer, we have first term as -16/9, second term as -64/81 and third term as -256/729. if we divide the second term by the first we have -4/9, if we divide the third by the second we have-4/9.
In conclusion, Only three are geometric sequences, a which is 3/16, 3/8, 3/4, 3/2, d which is 3,9,27,81 and f which is -4(4/9)^x

A rectangular piece of material with sides 150 cm and 100 cm is used to make a circular table cloth. the diameter of the completed cloth must be 0.9 m and 5 cm is provided for the hem. how much material is wasted?
The material wasted is 7915.375 sq cm.
What is area of rectangle?The product of its length and breadth.
Area = length* breadth
Given:
length= 150 ac, breadth = 100 cm
d= 0.9m 5cm
r= 47.5 cm
Area of rectangle,
= l * b
= 150*100

The probability of drawing three queens from a standard deck of cards is 0.000162.
What is the probability?Probability refers to a possibility that deals with the occurrence of random events.
The probability of all the events occurring need to be 1.
P(E) = Number of favorable outcomes / total number of outcomes
Total cards = 54
No. queens in a deck = 4
Probability of drawing a queen card = 4/54
Now that 1 queen has been taken, the no. of cards becomes = 53
and
no. of queens = 3
Probability of getting a queen again = (3/53)(4/54)
Two queens have already been removed.
No. of cards in the deck = 52
No. of queens in the deck = 2
Probability of drawing three queens
= (2/52)(3/53)(4/54)
= 0.000162 approximately

In one country, approximately 144,000 of 900,00 residences are rentals. Determine the percentage of residences in the country that are rentals
The 62.5% of residences in the country that are rentals if the total number of residence in the country is 144,000.
What is the percentage?It is defined as the ratio of two numbers expressed in the fraction of 100 parts. It is the measure to compare two data, the % sign is used to express the percentage.
We are assuming:
Total number of residence in the country = 144,000
In which 900,00 residences are rentals.
Percentage of residences in the country that are rentals:
= (90000/144000)×100
= 0.625×100
= 62.5%
Thus, the 62.5% of residences in the country that are rentals if the total number of residence in the country is 144,000.

find the area of the circle if radius is 6 and there is only 3/4 of the circled
Answer:
84.8
Step-by-step explanation:
Begin by finding the total area of the circle. You have been given the radius.
A = πr²
A = π(6)²
A = 36π
A = 113
If there is only 3/4 of the circle, then multiply the entire area by 3/4 to find the final answer.
113 x 3/4 = 84.8

A. Name the smallest angle and the largest angle of the following triangles: F 6 S 5 1. A J 5.03 7 5 G B H 5.1 2. D 4 3 E
Answer:
(smallest, largest) = (B, C), (D, E), (G, J)
Step-by-step explanation:
Side lengths of a triangle are proportional to the sine of the opposite angle. In a triangle, a larger angle will always have a larger sine. That means the smallest angle is opposite the shortest side, and the largest angle is opposite the longest side.
__
ΔABCThe shortest side is 5 units, opposite angle B. The longest side is 7 units, opposite angle C.
smallest angle: Blargest angle: CΔDEFThe shortest side is 3 units, opposite angle D. The longest side is 5 units, opposite angle E.
smallest angle: Dlargest angle: EΔGHJThe shortest side is 5 units, opposite angle G. The longest side is 5.1 units, opposite angle J.
smallest angle: Glargest angle: J_____
Additional comment
Angles in a triangle may exceed 90°. The sine function actually is decreasing for angles above 90°. However, since the total of angles of a triangle must be exactly 180°, there cannot be two angles in a triangle such that the smaller angle has the larger sine.

Point A in this figure is to be rotated 90° in a clockwise direction. The center of the rotation is the origin. A (0,5) C (6,3) B (2,-2) Where does point A end up?
Answer:

To rotate triangle ABC about the origin 90° clockwise we would follow the rule (x,y) → (y,-x), where the y-value of the original point becomes the new x-value and the x-value of the original point becomes the new y-value with the opposite sign.
