The lowest form of the ratio 84 : 99 is 28 : 33.
What are ratio and proportion?A ratio is a comparison between two similar quantities in simplest form.
Proportions are of two types one is the direct proportion in which if one quantity is increased by a constant k the other quantity will also be increased by the same constant k and vice versa.
In the case of inverse proportion if one quantity is increased by a constant k the quantity will decrease by the same constant k and vice versa.
Given, A ratio 84 : 99.
The lowest form of the ratio is when it can not be simplified further.
∴ 84 : 99.
= 28 : 33

The recursive formula is [tex]a_n\\[/tex] = 6n - 4.
What is Recursive formula?Any term of a series can be defined by its preceding term in a recursive formula (s).
A recursive formula consists of two parts: a declaration of the first term and a declaration of the formula connecting the succeeding terms.
For example: The recursive formula of an arithmetic sequence is,
an = an-1 + d.
Given:
2, 8, 14, 20
The above data shows Arithmetic Progression series.
a = 2
d = 8-2
d= 6
So, using Arithmetic Progression
[tex]a_n[/tex] = a+ (n- 1) d
[tex]a_n\\[/tex] = 2+ (n- 1)6
[tex]a_n\\[/tex] = 2+ 6n - 6
[tex]a_n\\[/tex] = 6n - 4
Hence, the recursive formula is [tex]a_n\\[/tex] = 6n - 4.

Daniela, Kieu, and Cameron decide to go to the movies one hot summer afternoon. The theater is having a summer special called Three Go Free. They will get free movie tickets if they each buy a large popcorn and a large soft drink. They take the deal and spend a total of $22.50 on large popcorns and soft drinks. The next week, they go back again, only this time, they each pay $8 for a ticket, they each get a large soft drink, but they share one large bucket of popcorn. This return trip costs them a total of$37.50. Use systems of equations to find the price of a large soft drink and the price of a large bucket of popcorn!
Answer:
Price of a large soft drink = $3
Price of large bucket of popcorn = $4.5
Step-by-step explanation:
Let the cost of one large popcorn = $P
And the cost of one large soft drink = $S
If Daniela, Kieu and Cameron avail the deal of Three Go Free,
3P + 3S = 22.50
P + S = 7.5 -----(1)
Next time they each pay $8 for a ticket, they each get a large soft drink but they share one large bucket of popcorn.
This trip cost them = $37.50
Cost of 3 tickets + Cost of 3 large soft drinks + Cost of one large bucket of popcorn = 37.50
(3 × 8) + (3 × S) + P = 37.5
24 + 3S + P = 37.5
3S + P = 13.5 -----(2)
By subtracting equation (1) from equation (2),
(3S + P) - (P + S) = 13.5 - 7.5
2S = 6
S = $3
From equation (1),
P + 3 = 7.5
P = $4.5
Therefore, price of a large soft drink is $3 and a large bucket of popcorn is $4.5
A toy store is having a sale. A video game system has an original price of $99. It is on sale for 40% off the original price. Find the sale price of the game system. Round to the nearest cent.
Answer:
The price would now be $59.40
Step-by-step explanation:
$59.4 is the sale price of the game system.
What is selling price?
The selling price is how much a buyer pays for a product or service.
Given,
A toy store is having a sale. A video game system has an original price of $99.
It is on sale for 40% off the original price.
We need to find how much 40% of $99.
40/100×99=0.4×99=39.6.
So sale price of the game system is $99-$39.6=$59.4.
Therefore sale price of the game system is $59.4.

24 + d = 30 fastt
Simplify (4.5)(−9)(−1.8)
Find the value of x.
Answer:
x=55
Step-by-step explanation:
you have to add the three angles to get 180 first. 180- 21-34=125.
then take the missing angle inside the triangle (125) and subtract by 180.
180-125=55
Answer:
x = 55
Step-by-step explanation:
We know that triangles add up to 180 degrees, so let's start with that. Keep in mind that "y" will be the third degree of the triangle.
21+34+y = 180
55+y = 180
y = 125
Okay, now we know that the third degree is 125. Also, the line that 125 and x are on is a straight line. All straight lines are 180 degrees. Subtract 180 and 125 to get your answer.
180-125 = 55
So your final answer will be x=55, hope this helped!
