Add the first 12 terms of this sequence:
15, 45, 135, 405, 1215, ...
Answer:
Step-by-step explanation:
a₁ = 15
a₂/a₁ = 45/15 = 3
a₃/a₂ = 135/45 = 3
...
It is a geometric sequence with a common ratio r=3.
Sum of first 12 terms = a₁·(1-r¹²)/(1-r)
= 15·(1-3¹²)/(1-3)
= 15·(-531,441)/(-2)
= 3,985,800

Given the central angle, name the arc formed.
∠RQT
A. SV
B. RT
C. RQT
D. SRV
The arc formed by the central angle ∠RQT is RT. The correct option is option B.
Given: The central angle ∠RQT
To find: The arc formed by the given central angle
A central angle of a circle is an angle formed by any two radii of the circle. These radii each intersect the circle on a point, and the portion of that circle between the two points is called an arc.
As can be seen from the given figure, Q is the center of the circle and RQ and QT are radii of the circle. Clearly, the central angle ∠RQT is formed by the radii RQ and QT.
The points where these radii intersect the circle are R and T respectively. Then, the portion of the circle between R and T is the required arc.
However, this portion can be taken in two ways; the bigger portion between them (found by moving anti-clockwise from R towards T) and the smaller portion between them (found by moving clockwise from R towards T). These are called the major arc and the minor arc between R and T respectively.
Since it is not explicitly mentioned which arc is required, we will tacitly assume that the minor arc is required.
The minor arc between R and T is named by their end points, that is, as RT.
While not required, it should be noted that the major arc between R and T should be named by their end points and a point between them on the arc (for example RVT or RUT)
Thus, the arc formed by the central angle ∠RQT is RT.

26. A dealer was paid 5% commission on all the recharge cards he sold. If he sold N50,000.00 worth of cards, how much commission did he get?
Answer:
Its N2500
Step-by-step explanation:
5% of 50000 is 2500, so thats how much commision he got
The dealer earned a commission of N2,500.00 on the sale of recharge cards worth N50,000.00.
To calculate the commission earned by the dealer, we need to determine 5% of the total value of the recharge cards sold.
Given that the dealer sold N50,000.00 worth of cards, we'll calculate the commission using the following formula:
Commission = (Percentage/100) * Total Value
In this case, the percentage is 5% and the total value is N50,000.00.
Using the formula, we have:
Commission = (5/100) * N50,000.00
Simplifying the equation:
Commission = 0.05 * N50,000.00
Commission = N2,500.00

It can be useful to memorize the decimal equivalents of the reciprocals of the numbers up to 12.
1/12 = 0.0833...(repeating 3)
1/11 = 0.0909...(repeating 09)
1/10 = 0.1
1/9 = 0.111...(repeating 1)
1/8 = 0.125
1/7 = 0.142857...(repeating the same 6 digits)

1/5 = 0.2
1/4 = 0.25
1/3 = 0.333...(repeating 3)
1/2 = 0.5
Of course, any of these is expressed as a percentage by multiplying by 100%. 1/8 = 12.5%, 1/6 = 16.6...% (repeating 6)

Century Page: Date: A man bought a radio for Rs. 2000 and fixed its price so that after giving 20% discount he made 10% profit. Find the fixed price of the radio
With a 10% profit the radio would be 2000 x 1.10 = 2,200
A 20 % discount means it would sell for 80% of the total price.
Divide the 2200 by 80% to get the fixed price:
2200/0.8 = 2750
Fixed price = 2750

If
A. x = 62; mZROS = 31°
B. x = 60; mZROS = 28°
C. x= 31; mZROS = 62°
D. X = 28; mZROS = 60°
Answer:
x = 31
ROS = 62
Step-by-step explanation:
QOR + ROS = 90 degrees as indicated by the box
28+ 2x = 90
Subtract 28 from each side
2x = 90 -28
2x = 62
Divide by 2
2x/2 = 62/2
x = 31
ROS = 2x = 2*31 = 62
Answer:
C. x= 31; mZROS = 62°
Step-by-step explanation:
90=28+2x
2x= 90-28
2x= 62
x= 62/2
x=31°
2(x)= 2× 31 = 62

One number is eight less than a second number. Five times the first is 6 more than 6 times the second. Find the numbers.
The value of the first number is -
Answer:
-42/11
Step-by-step explanation:
x = y - 8
5x = 6 - 6y
So now solve the system of equations, divide everything in the second equation by 5 to get it to x = 6/5 - 6y/5
Now...
x = y - 8
x = 6/5 - 6y/5
Now substitute first equation into the second and x is gonna be -42/11 or the first number

Mary is thinking of a mystery number. She reduces it by 15% then subtracts 5. The result is 29. Determine the mystery number
Answer:
40
Step-by-step explanation:
Let x represent the mystery number.
Create an equation to represent the situation, then solve for x:
0.85x - 5 = 29
0.85x = 34
x = 40
So, the mystery number is 40.
Desde cierto paradero se transportan 300 pasajeros en
4 microbuses. ¿Cuántos micros se deben aumentar para
que por cada 3 micros se transporten 90 pasajeros?
Se necesitan 10 micros si queremos que cada 3 micros transporten 90 pasajeros.
En principio, sabemos que 300 pasajeros pueden transportarse en 4 microbuses.
Entonces, el numero de pasajeros que va por cada micro será el cociente entre el numero de pasajeros y el numero de micros:
N = 300/4 = 75
Queremos responder:
¿Cuántos micros se deben aumentar para que por cada 3 micros se transporten 90 pasajeros?
Definamos X como el numero de grupos de 3 micros que tendriamos en esta situación.
Entonces 300 sobre X, debe ser igual a 90 (el numero de pasajeros que va en cada grupo de 3 micros)
300/X = 90
300 = 90*X
300/90 = X = 3.33...
Notar que el número total de micros sera 3 veces X:
3*X = 3*3.33.... = 10
Se necesitan 10 micros.
