Answer:
[tex]-291[/tex]
Step-by-step explanation:
From the three terms, we can conclude that the arithmetic sequence for this sequence is [tex]a_{n}=4+(n-1)(-5)[/tex].
[tex]a_{60}=4+(60-1)(-5)[/tex]
[tex]=-291[/tex]
∴ The 60th term of the arithmetic sequence is [tex]-291[/tex].

$81 from her mother to buy tickets to a concert. If Sara decreases her debt by
$
4.50
$4.50 each week, how many weeks will it take her to pay off the whole amount she owes her mother?
Answer:
It will take 18 weeks
Step-by-step explanation:
Here, we are told that she owes a total of $81 which decreases at a rate of $4.50 per week
The number of weeks it will take to finish paying the debt will be the amount owed divided by the payment per week
Mathematically that is 81/4.5 = 18

Alex bought a game $15.00. Because he works at GameStop he gets an employee discount of 10%. What was the cost of his game after the discount?
Answer:
$13.50
Step-by-step explanation:
Multiply the price by the discount, then subtract that number from the original price.
15.00 x 10% = $1.50
$15.00-$1.50 = $13.50
Answer:
$13.5
Step-by-step explanation:
Discount is 10%
So 15*10/100=$1.5
$15-$1.5=$13.5
Weight of 8 bags of sugar is 400 kg. The weight of 30 such bags will be ------------------------------------
Answer:
1500 kg
Step-by-step explanation:
8 bags = 400 kg
1 bag = 400/8
= 50 kg
30 bags = 30×50
= 1500 kg
Answer:
Step-by-step explanation:
First of all, calculate the weight of 1 bag of sugar first.
400/8=50
So 1 bag of sugar is 50 Kg.
There are 30 bags of sugar so multiply 50 by 30
You will get 1,500Kg for 30 bags of sugar.

Answer:abd
Step-by-step explanation:
Answer:
A B and D
Step-by-step explanation:
these numbers could represent percents like 95% off 85% off or 55% off
so if n represents 1 item you would do 0.95(1) which equals 0.95 off of the original price which would make it 0.05
hope this makes sense

The cost y (in dollars) to rent a kayak is proportional to the number x of hours that you rent the kayak. It costs $27 to rent the kayak for 3 hours.
a. Write an equation that represents the situation.
Answer:
If the cost y is proportional to the number of hours x:
y = kx where k is the constant of proportion.
Given $27 for 3 hours, find k
27 = 3k
k = 9
Your equation is: y = 9x
From this, given a value for y or x you can plug it in to find the other.

4x – 2y = 16
O the y in the first equation
the x in the second equation
the x in the first equation
the y in the second equation
Answer:
The y in the second equation
Step-by-step explanation:
The y in the second equation is preceded by a negative coefficient, therefore it will be positive when added to the other side. All the numbers in the equation are even and easily divided by 2 as well. 2 is also the smallest number in the equation, so the remaining numbers will remain whole.

A scooter travels 30 feet in 2 seconds at a constant speed. b. Complete the double number line to show the distance the scooter travels after 1, 3, 4, and 5 seconds.
Answer:
15 feets ; 45 feets ; 60 feets ; 75 feets
Step-by-step explanation:
Given that:
Moving at a constant speed ; Distance traveled in 2 seconds = 30 feets
The traveling speed = distance / time
Traveling speed = 30 feets / 2 seconds
Traveling speed = 15 ft/s
Distance traveled = traveling speed * time
Distance traveled after 1 second :
Time = 1 second
15ft/s * 1s = 15 ft
Distance traveled after 3 second :
Time = 3 second
15ft/s * 3s = 45 ft
Distance traveled after 4 second :
Time = 4 second
15ft/s * 4s = 60 ft
Distance traveled after 5 second :
Time = 5 second
15ft/s * 5s = 75 ft

A group of college students developed a
solar-powered car and entered it in a
race. The car travels at a constant speed
of 100 meters per 4 seconds.
Answer:
50m/s
Step-by-step explanation:
Since we are not told what to find, we can as well look for two speed of the car in meter per seconds
If the car travels at a constant speed of 100 meters per 4 seconds, the we can say;
100 meters = 4seconds
Since we want to know the speed in metres per second, we will say;
X meters = 1second
Equating both
100 meters = 4seconds
X meters = 1seconds
Cross multiply
4×X = 200×1
4X = 200
Divide both sides by 4
4X/4 = 200/4
X= 50
Hence the of the car in meter per seconds is 50meters per second

An amusement park has 32000 visitors per day when it charges $70 per person. For each $2 increase in price, the park loses about 800 visitors answer. How much should the park charge to maximize the daily revenue? What is the maximum daily revenue?
Answer:
Maximum daily revenue = $2,249,600
Step-by-step explanation:
If you approach this problem with a trail and error mindset you can quickly calculate that if you take an increase of $6 per ticket or $76 per ticket, then subtract the equivalent loss of visitors which would be 800 * 3 or 2,400 then you get 29,600 visitors. By simply multiplying this number by the cost of the tickets you achive 2,249,600 daily. This could be wrong as I did not use a formula.

Hcf of two numbers is 2 and lcm is 54 if one of the number is 27 find the other number
Answer:
4
Step-by-step explanation:
Given that:
Let the two numbers = a and b
H. C. F of the two numbers = 2
L.C.M of the two numbers = 54
If a = 27 ; b =?
The product of a and b = product of their L. C. M and H. C. F ;

27 * b = 2 * 54
27b = 108
b = 108/27
b = 4

In the first event, the eighth graders are running a baton relay race with three other classmates. The teams top speed for each leg is 56.8 one seconds, 59.22 seconds, 57.39 seconds, and 60.11 seconds. Use the information to protect his teams best time for the race. Each leg of the race from part a is the same distance. Calculate the teams average time for each leg of the race. Show your work
Answer:
The best time is 56.81 seconds
Average leg time is 58.3825 seconds
Step-by-step explanation:
Here, we want to start by stating the team’s best time for the race
The team’s best time for the race is the smallest time spent on a lap
From the times given, the best time is 56.81 seconds
Now, we want to calculate the average time
We simply add up all these and divide by count
Mathematically, that will be;
(56.81 + 59.22 + 57.39 + 60.11)/4 = 58.3825 seconds

At a school, 40% of the sixth-grade students said that hip-hop is their favorite kind of music. If 100 sixth-grade students prefer hip hop music, how many sixth-grade students are at the school? Do not include units (students) in your answer.
Answer:
We have 250 sixth-grade students are at the school
Step-by-step explanation:
Let the total number of sixth graders be represented as x
Therefore we solve the question nas shown below:
40% of x = 100 sixth grade students that prefer Hip -pop
= 40/100 × x = 100
= 40x /100 = 1000
Cross y
40x = 100 × 100
40x = 10000
x = 10000/40
x = 250 students
Hence, we have 250 sixth-grade students are at the school
Matilda needs at least $100 to in her savings account to keep it open. She already has $330 but withdraws $11 a month for fun. Write and solve an inequality to find how many months she will be able to keep her account open. Interpret the solution.
Step-by-step explanation:
Step one:
given data
we are told that she wants her balance to be at least $100
y=100-------1
the expression relating her current balance and spending rate is
let y be the total and m be the number of months
y=330-11m----------2
Required
the number of months m
equating 1 and 2 we have
100=330-11m
11m=330-100
11m=230
m=230/11
m=20.9
m=21 approx
This means that she will keep her account open for 1 year 9 months
A table is made using the following two patterns.
Pattern 2: Starting number: 12, Rule: Add by 8
Pattern y: Starting number: 60, Rule: Divide by 2
Complete the table for the given patterns.
2
Y
12
60
Step-by-step explanation:
add 8 to each x coordinate and divide 60 by 2 and then divide that by 2
The complete table for the given pattern is,
x: 12, 20, 28.
y: 60, 30, 15.
To complete the table for the given patterns, we can follow the specified rules for each pattern:
Pattern x: Starting number: 12, Rule: Add by 8
To generate the numbers in this pattern, we start with the given starting number, which is 12. Then, we apply the rule of adding 8 to each successive number.
12 + 8 = 20
20 + 8 = 28
So, the completed table for Pattern x would be:
x
12
20
28
Pattern Y: Starting number: 60, Rule: Divide by 2
For this pattern, we start with the given starting number, which is 60. Then, we apply the rule of dividing each successive number by 2.
60 ÷ 2 = 30
30 ÷ 2 = 15
So, the completed table for Pattern Y would be:
Y
60
30
15
By following the respective rules for each pattern, we have filled in the missing values in the table.
