1/8 1/4 3/8 1/2 5/8 3/4
Step-by-step explanation:
First, we must organize the order of the numbers from least to greatest. This will keep the data organized, (and maybe get you extra points). So, let's convert all the fractions so that they will have a denominator of 8.
1/4 = 2/8, 1/2 = 4/8, 3/4 = 6/8.
Now in order we get: 1/8, 1/4, 3/8, 1/2, 5/8, 3/4.
Second, count the number of each fraction that occurs in the data set. Now, put them next to the fractions.
1/8 has 2, 1/4 has 3, 3/8 has 4, 1/2 has 3, 5/8 has 1, 3/4 has 2.
Third, let's put together all the data in to the line plot. First, draw a horizontal line. Then, put dashes intersecting the horizontal line, 6 of them. Beneath the dashes, write the fractions from least to greatest. Above the dashes, draw the number of X's to represent the number of occurrences on each fraction.
A fruit juice recipe calls for 2 parts orange juice and 8 parts pineapple juice. Which proportion can be used to find the amount of orange juice, j, that is needed to add to 18 L of pineapple juice?
2 over 8 equals j over 18
8 over 2 equals j over 18
8 over j equals 2 over 18
16 over 18 equals j over 100
Answers
The correct proportion to use to find the amount of orange juice, j, needed to add to 18 L of pineapple juice is:
2/8 = j/18
This proportion relates the ratio of orange juice to pineapple juice in the recipe (2:8) to the amount of orange juice needed to add to 18 L of pineapple juice. By cross-multiplying, we can solve for j as follows:
2/8 = j/18
218 = 8j
36 = 8*j
j = 36/8
j = 4.5
Therefore, you would need to add 4.5 L of orange juice to 18 L of pineapple juice to create the fruit juice recipe that calls for a ratio of 2 parts orange juice to 8 parts pineapple juice.
Answer:
2 over 8 equals j over 18Step-by-step explanation
2 over 8 equals j over 18
This proportion represents the ratio of orange juice to pineapple juice in the recipe. By setting up the proportion, we can solve for the value of 'j,' which represents the amount of orange juice needed.
So, the correct proportion is:
2 over 8 equals j over 18
John currently has $500 in his lunch account. He spent $15 each day on lunch. In how many days will John have $245?
Answers
Answer:
18 days.
Step-by-step explanation:
Step 1) Building an arithmetic sequence
We can build an arithmetic series with the given information.
The \(n\)th term of an arithmetic series is given by the formula \(a_n = a_1 + (n - 1)d\) .
\(a_1 = 500\\d = -15\\\to a_n = 500 - 15(n - 1) = 515 - 15n\)
Step 2) Finding the n for which a(n) = 245
As this step's title implies, we need to solve the equation \(a_n = 245\):
\(515 - 15n = 245 \text{ / Subtract 245}\\515 - 15n - 245 = 245 - 245\\\to 270 - 15n = 0 \text{ / Add 15n}\\270 - 15n + 15n= 0 + 15n\\\to 270 = 15n \text{ / Divide by 15}\\\frac{270}{15} = \frac{15n}{15}\\\to 18 = n\)
John will have $245 in 18 days.
Answer:
17 days
Step-by-step explanation:
Since John starts with $500 and each day, he’ll spend $15 on lunch. This means that:
On his first day, he’ll spend $15.On his second day, he’ll spend another $15 which is total spend of $30 ($15 x 2)On his third day, he’ll spend total of $45 ($15 x 3)Therefore, on his nth day, he’ll spend $15n where n represents the day. The problem can be modeled into an equation of \(\displaystyle{500-15n=245}\) since we will be finding how many days it will take to reach $245.
Then solve for n-term which we determines as the day variable:
\(\displaystyle{500-15n-245=0}\\\\\displaystyle{255-15n=0}\\\\\displaystyle{255=15n}\\\\\displaystyle{n=17}\)
Therefore, on his 17th day, he’ll have $245. Hence, the answer is 17 days.
A recent conference had 650 people in attendance. In one exhibit room of 70 people, there were 18 teachers and 52 principals. What prediction can you make about the number of principals in attendance at the conference?
There were about 167 principals in attendance.
There were about 316 principals in attendance.
There were about 483 principals in attendance.
There were about 1,878 principals in attendance.
Answers
There were about 483 principals in attendance.
The correct option is (3).
What is Arithmetic?The mathematical branch known as arithmetic deals with the study and application of numbers, their relationships, and mathematical observations.
As per the given data:
The total number of people in the recent conference = 650
The total number of people in one exhibit room = 70
Number of teachers in one exhibit room = 18
Number of principals in one exhibit room = 52
To find out the total number of exhibit rooms:
= Total number of people in the conference / total people in one room
= 650 / 70
= 9.28 = 9 {rounding off to the nearest integer}
Number of principals in one exhibit room = 52
Total number of principals in the conference:
= Number of rooms × Principals in one room
= 9 × 52 = 468 which is equal to 483 {approximate answer}
There were about 483 principals in attendance.
Hence, There were about 483 principals in attendance.

D. 1200 gallons
Step-by-step explanation:
Fractions of the total are given, as is the quantity the difference of those fractions represents. These can be used to write an equation to find the total.
SetupLet g represent the total number of gallons of fuel sold. Then the number of gallons of 87-octane sold is 0.50g, and the number of gallons of 89-octane sold is 0.35g. The difference is said to be 180 gallons:
0.50g -0.35g = 180
SolutionCollecting terms gives ...
0.15g = 180
Dividing by the coefficient of g, we find ...
g = 180/0.15 = 1200
The gas station sold 1200 gallons of fuel last weekend.

To find f(f^(-1)(9)), we need to first find f^(-1)(9), the inverse of f(9).
Given that f(4) = 9, we know that f^(-1)(9) is equal to 4.
Therefore, f(f^(-1)(9)) is equivalent to f(4).
Given that f(4) = 9 according to the problem statement, we can conclude that f(f^(-1)(9)) = 9.

Determine the direction and degree of rotation used to create the image.
90° counterclockwise rotation
270° clockwise rotation
90° clockwise rotation
180° counterclockwise rotation
Answers
Answer: 90° clockwise rotation
Step-by-step explanation:
The rules for rotation are below:
90° clockwise rotation = (x, y)→(y, -x)
270° clockwise rotation = (x, y)→(-y, x)
180° counterclockwise rotation = (x, y)→(-x, -y)
90° counterclockwise rotation = (x, y)→(-y, x)
Let's take point B. Point B's coordinates are (3, -2). Point B' is (-2,-3). -x would be -3, and y stays the same.
Therefore, the answer is 90° clockwise rotation.

Considering area (A) of garden as 30 square feet:
30 = x(2x+7)
Now we need to expand it:
x(2x+7) = 2x^2 + 7x
2x^2 + 7x = 30
Adding this into an Algebra calculator gives us 5/2 or 2.5
So x = 2.5
To prove this:
2(2.5) + 7 = 12
14 * 2.5 = 30
(2x+7) x = 30
you can distribute to make this easier
2x^2 + 7x = 30
you can plug this into quadratic formula by setting the equation =0, so:
2x^2 +7x -30 = 0
where 2x^2 = a
7x = b
and -30 = c
you can plug this into your calculator and get an answer of
X = 2.5

Answers
141.37 square inches
Answer:
about 141.4 square inches
Step-by-step explanation:
You want the area of icing on a cake that is 10 inches in diameter and 2 inches high.
IcingThe icing on a cake covers the lateral surface area and the area of the circular top. In terms of diameter, the sum of those areas is ...
icing area = πdh +(π/4)d² = πd(h +d/4)
icing area = π(10 in)(2 in + (10 in)/4) = π(10 in)(4.5 in)
icing area = 45π in² ≈ 141.4 in²
The area of icing on the cake is about 141.4 square inches.
