Last week, Kip went to the fair. It costs $4.59 to enter the fair and $1.25 per ticket. In the equation below, x represents the number of tickets Kip bought, and y represents the total amount Kip spent. y = $1.25x + $4.59 If Kip spent $23.34 at the fair, how many tickets did he buy? A. 12 B. 15 C. 22 D. 19
Answer:
B.) 15
Step-by-step explanation:
Fist you want to plug in 23.34 as your Y. Next you want to subtract 4.59 from 23.34. Finally, to get the variable alone, divide the answer you got from subtracting by 1.25.
Which of the following numbers can be expressed as repeating decimals? 4/7, 2/5, 7/8, 4/9
Answer:
4/7 & 4/9
Step-by-step explanation:
4/7 <-------- repeating decimal/rational4/9 <-------- repeating decimal/rationalNumbers with a repeating pattern of decimals are rational because when you put them into fractional form, both the numerator a and denominator b become non-fractional whole numbers. ------------------------------- 4/9A repeating decimal is a decimal number that goes on forever. We want to know if the decimal number you get when you divide the fraction 4/9 (4 ÷ 9) is repeating or non-repeating.Here are the steps to determine if 4/9 is a repeating decimal number:1) Find the denominator of 4/9 in its lowest form.The greatest common factor (GCF) of 4 and 9 is 1. Convert 4/9 to its simplest form by dividing the numerator and denominator by its GCF:4 ÷ 1/ 9 ÷ 1 = 4/9Thus, the denominator of 4/9 in its lowest form is 9.2) Find the prime factors of the answer in Step 1.The prime factors of 9 are all the prime numbers that you multiply together to get 9. The prime factors of 9 are:3 x 33) Determine if 4/9 is repeatingA fraction is a repeating decimal if the prime factors of the denominator of the fraction in its lowest form do not only contain 2s and/or 5s or do not have any prime factors at all. This is the case here, which means that our answer is as follows:4/9= repeating------------------------------------------ 4/7A repeating decimal is a decimal number that goes on forever. We want to know if the decimal number you get when you divide the fraction 4/7 (4 ÷ 7) is repeating or non-repeating.Here are the steps to determine if 4/7 is a repeating decimal number:1) Find the denominator of 4/7 in its lowest form.The greatest common factor (GCF) of 4 and 7 is 1. Convert 4/7 to its simplest form by dividing the numerator and denominator by its GCF:4÷1/7÷1=4/7Thus, the denominator of 4/7 in its lowest form is 7.2) Find the prime factors of the answer in Step 1.The prime factors of 7 are all the prime numbers that you multiply together to get 7. The prime factors of 7 are:73) Determine if 4/7 is repeatingA fraction is a repeating decimal if the prime factors of the denominator of the fraction in its lowest form do not only contain 2s and/or 5s or do not have any prime factors at all. This is the case here, which means that our answer is as follows:4/7= repeatingTherefore, the fraction 4/7 and 4/9 can be represented as repeating decimals.If you roll a 6-sided die 6 times, what is the best prediction possible for the number of times you will roll a six?

A car travels at a speed of 65 miles per hour. How far will it travel in 5 hours?
Answer: Distance = 325 miles
Step-by-step explanation:
Distance = speed*time
We can plug in the values given for time and speed:
Distance = 65 miles/h * 5 hours
Distance = 325 miles
Answer:
325 miles
Step-by-step explanation:
To find out how far the car will travel in 5 hours, we first need to know how far it will travel in one hour.
Well, we are given that information.
Since we know that the car travels 65 miles in 1 hour, we just have to multiply 65 by the number of hours it will drive, which is 5 in this case.
5 x 65 = 325
The car will drive 325 miles in 5 hours.

Anuar has a collection of 80 toy vehicles. 3/5 of his toy vehicles are cars. The rest are motorcycles and buses. The number of motorcycles is 3 times the number of buses. How many toy motorcycles does Anuar have?
Answer:
He has 24 motorcycles
Step-by-step explanation:
I hope I could help!
Answer:
36 motorcycles
Step-by-step explanation:
calculate [tex]\frac{3}{5}[/tex] of 80
= [tex]\frac{3}{5}[/tex] × 80 ( cancel 5 and 80 by 5 )
= 3 × 16 = 48
there are 48 motorcycles and buses
let x be the number of buses then 3x is the number of motorcycles , then
x + 3x = 48
4x = 48 ( divide both sides by 4 )
x = 12
number of motorcycles = 3x = 3 × 12 = 36
(a+4)^(2)-(a-1)^(2) please solve this rn please i need it
Answer:
10a + 15
Step-by-step explanation:
(a+4)^(2)-(a-1)^(2)
(a+4)^(2)
(a+4)(a+4) = (a^2 + 8a + 16)
(a-1)^(2)
(a-1)(a-1) = (a^2 -2a + 1)
(a^2 + 8a + 16) - (a^2 -2a + 1)
a^2 + 8a + 16 - a^2 +2a - 1
10a + 15

1,428
1,476
2,856
2,952
Answer:
B
Step-by-step explanation:
This is a summation problem. The difference is the same all the way up.
First we have to find the last term.
t24 = a + (n - 1)*d
a = 4
n = 24
d = 5
t24 = 4 + (24 - 1)*5
t24 = 4 + 23*5
t24 = 4 + 115
t24 = 119
Now you can calculate the total
Sum = (a + t24)*n/2
Sum = (4 + 119)*24/2
Sum = (4 + 119)*12
Sum = 123 * 12
Sum = 1476

Answer:
Yours: mean: 17; median: 17; mode: none
Friends: mean: 16.4; median: 17; mode: 20
You have the higher mean.
Step-by-step explanation:
a.
Your mean:
(18 + 16 + 19 + 15 + 17) / 5
= 17
Your median:
15 , 16, 17, 18, 19
= 17
Your mode:
15 , 16, 17, 18, 19
= No mode (no number comes up repeatly)
Your friend's mean:
(20 + 20 + 13 + 12 + 17) / 5
= 16.4
Your friend's median:
12, 13, 17, 20, 20
= 17
Your friend's mode:
12, 13, 17, 20, 20
= 20
b. Comparing your means, you have the higher mean

Answer:
a. the percentage of the students who not drive a car is 44%
b. Number of students in 1 car
c. 1 = 3 i think
Step-by-step explanation:
11 / (14 + 11)
11/25
average is 2 i think
you can change the denominator to 100 by multiply 4, dont forget to do the same to the top
44/100
the percentage of the students who not drive a car is 44%
mean is average. to find the mean add all the given then divide by how many
sooo i think since it said "number of students in each car"
1 + 2 + 3 / 3
6 / 3
2 i think?
The solutions to the equations is
The percentage of students who do not travel by car is given by the equation A = 44 %
The mean number of students in each car is 2 students and the missing frequency is 3 cars
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
The total number of students in the school = 25 students
The number of students who travel by car = 14 students
The number of students who do not travel by car = 11 students
So , the percentage of students who do not travel by car = ( number of students who do not travel by car x total number of students in the school ) x 100
Substituting the values in the equation , we get
The percentage of students who do not travel by car A = ( 11/25 ) x 100
On simplifying the equation , we get
The percentage of students who do not travel by car A = 0.44 x 100
The percentage of students who do not travel by car A = 44 %
And , the missing frequency is f = 3 cars
The total number of students in one car = 1 + 2 + 3 = 6 students
So , the mean number of students in each car = 6/3 = 2 students
Hence , the equations are solved

If 2x/2y= 16, what is x-y
Answer:
15
Step-by-step explanation:
2x/2y = 16
First, we can cancel out the 2s as there is one on the numerator and another on the denominator.
x/y = 16
To make it fraction form, we know that 16 = 16/1.
x/y = 16/1
We then get x and y.
x = 16
y = 1
x - y = 15
