Final answer:
Joyce has read 9/10 of her book over the course of three days by adding together the fractions of the book she read each day and simplifying the result.
Explanation:
To determine the part of the book Joyce has read over the three days, we need to add the fractions representing the parts read each day. On Monday, Joyce reads 1/6 of her book, on Tuesday she reads 2/5, and on Wednesday she reads 1/3. Thus, we add these fractions together.
The Least Common Denominator (LCD) for 6, 5, and 3 is 30. We convert each fraction to have this common denominator:
1/6 = 5/302/5 = 12/301/3 = 10/30Now, we sum the fractions:
5/30 + 12/30 + 10/30 = (5 + 12 + 10)/30 = 27/30
27/30 can be simplified to 9/10 after dividing both numerator and denominator by 3. So, Joyce has read 9/10 of her book over the three days.
The side lengths of the state flag of Colorado are in the ratio 2:3. If the flag is 12 feet long, what is it’s height
Answer:
18 feet
Step-by-step explanation:
Let the height be x
We are given that The side lengths of the state flag of Colorado are in the ratio 2:3.
Length: Height = 2:3
Length of the flag is 12 feet long
Length : Height = 12:x
So, ATQ
2:3::12:x
[tex]\frac{2}{3}=\frac{12}{x}[/tex]
[tex]x=\frac{12 \times 3}{2}[/tex]
[tex]x=18[/tex]
Hence it’s height is 18 feet
To find the height of the Colorado state flag, we can use the given ratio of side lengths and solve for the unknown height using a proportion.
Explanation:To find the height of the Colorado state flag, we can use the given ratio of side lengths – 2:3. Since the given length is 12 feet, we can set up the ratio equation as follows:
2/3 = 12/x
To solve for x, we can cross multiply:
2x = 3 * 12
Simplifying further, we get:
2x = 36
Dividing both sides by 2, we find that:
x = 18
Therefore, the height of the Colorado state flag is 18 feet.

the heights of subjects in a clinical trial of a new drug is it qualitative or quanitative?
Answer:
The heights of subjects in a clinical trial of a new drug is a quantitative data.
Step-by-step explanation:
Qualitative: If a data represents characteristics, color, quality and it is non-numerical in nature, then it is known as qualitative data.
For example:- favorite color, game, hobby, etc.
Quantitative: If a data represents numerical values, then it is known as qualitative data.
For example:- height, weight, age, etc.
The heights of subjects in a clinical trial of a new drug can be represented by numerical values.
Therefore the heights of subjects in a clinical trial of a new drug is a quantitative data.

If K is the midpoint of jl ,jk =9x-1 and kl =2x+27, find jl
Answer:
JL = 70
Step-by-step explanation:
If K is the midpoint of the segment, then JK = KL
JK = KL
9x-1 = 2x+27
Subtract 2x from each side
9x-2x -1 = 2x+27-2x
7x-1 = 27
Add 1 to each side
7x-1+1 = 27+1
7x = 28
Divide each side by 7
7x/7 = 28/7
x =4
But we want to find JL
JL = JK + KL
JL = 9x-1 +2x+27
Combine like terms
JL = 11 x+ 26
Substitute x =4
JL = 11*4+26
JL = 44+26
JL = 70
The length of line segment JL, when K is its midpoint and given jk = 9x - 41 and kl = 2x + 27, is 70.
Explanation:This question is related to geometry and specifically the section on line segments. Firstly, if K is the midpoint of line segment JL, that means JK and KL are of equal lengths. So, we can set their equations equal to each other:
9x - 1 = 2x + 27
To solve this equation, start by subtracting 2x from both sides to isolate the variable x on one side:
7x - 1 = 27
Next, add 1 to both sides:
7x = 28
Dividing both sides by 7 gives:
x = 4
Substitute x = 4 into either of the equations, say kl = 2x + 27, gives the length of segment KL as:
kl = 2(4) + 27 = 35
The length of JL would then be twice the length of KL (since K is the midpoint) so:
jl = 2 * 35 = 70.

Help with recursive Arithmetic sequence
Answer:
Slope is 5, y-int is 1, and f(n) = 5n+1
Step-by-step explanation:
So, since we are dealing with an arithmetic sequence, it is linear. If you notice, it is just adding 5 from the previous term. This represents a slope of 5. Increase of 1 in x and increase of 5 in y. Then, f(1) = 6. Since 1 x 5 is 5, and 5 + 1 = 6, the b is 1. This is because the normal 5x is deviated by 1. Since it is arithmetic, that 1 unit deviation will carry on. The last question basically says just write the y=mx + b but just use n and f(n), which is f(n) = 5n + 1.

The square of a whole number is between 4500 and 4900. The number must be between...
55 and 60
60 and 65
65 and 70
70 and 75
The square of a whole number between 4500 and 4900 must be between 67 and 69, hence the number is in the range of 65 to 70 excluding 70.
The student's question involves finding the whole number whose square falls between 4500 and 4900. To solve for the range of whole numbers, we need to take the square root of both limits. Since the square root of 4500 is approximately 67.08 (rounded down to the nearest whole number is 67) and the square root of 4900 is exactly 70, the whole number must be between 67 and 70. However, since 70 squared gives us 4900, we exclude it from the possible numbers. Therefore, the possible numbers are 67, 68, and 69, which means the correct answer is between 65 and 70.

Of the students in your class, 12% are left-handed. What fraction of the students are left-handed? Are there more right-handed or left-handed students? Explain. Write your answers in simplest form.
of the students are left-handed.
of the students are right-handed.
A comparison of these two fractions is:
Final answer:
In a classroom with 12% left-handed students, the fraction representing them is 3/25 after simplification, and with 88% right-handed students, their fraction is 22/25. Since 22/25 is greater than 3/25, there are more right-handed students.
Explanation:
If 12% of the students in your class are left-handed, the fraction of students that are left-handed is 12/100, which can be simplified to 3/25 by dividing both the numerator and the denominator by 4. There are clearly more right-handed students because if 12% are left-handed, then 100% - 12% = 88% are right-handed. The fraction of right-handed students is 88/100, which simplifies to 22/25. Comparing the two fractions, 3/25 for left-handed students and 22/25 for right-handed students, it’s evident that there are more right-handed students in your class.
I currently have 4 wild bunnies running around my yard. They are freaking annoying. Especially because they are doubling in number every month. Assuming this continues how many bunnies will be annoying me in 2 years.
Answer:
y = 67108864 rabbits
Step-by-step explanation:
The equation for growth is
y= a(b)^(t)
where a is the initial amount
b is the growth rate and
t is the time in months
2 years = 24 months
Assuming the population doubles at the end of the 1st month
Substituting in what we know
y = 4 (2) ^ (t)
y= 4 *2 ^ 24
y = 4*16777216
y = 67108864 rabbits
If they do not double at the end of the first month and wait until the second month, divide this number by 2
y = 4 (2) ^ (t-1)
y= 4 *2 ^ 23
y = 4*8388608
y = 33554432 rabbits

Three-tenths of the total volume, v, of water in a bucket spills.
Which statement explains why 310x and 0.3x can each find the volume of the water that spilled?
The fraction 310 is equivalent to the decimal 0.03. Therefore, 310x can be rewritten as 0.03x.
The expressions are not equivalent.
Multiplying by 3 is the same as multiplying by 30%.
Multiplying by 310 is the same as multiplying by 30%.
Answer:
The expressions are not equivalent.
Step-by-step explanation:
Three-tenths of the total volume, v = [tex]\frac{3}{10} (v)[/tex]
= 0.3 × v --- (1)
But, 310x is 310 × v --- (2)
Since (1) and (2) represent the same volume,
0.3 × v = 310 × v
Divide both sides by v,
0.3 = 310 which is a contradiction.
Therefore, the expressions are not equivalent.

Answer:
g=4
Step-by-step explanation:
If you're solving for g, you need to get it alone on one side. The way I did so was to subtract 7 from each side.
15 = 2g + 7
-7 -7
If you do that, the 7 on the right cancels out and you're left with 8 = 2g. To get the g alone, you divide it by it's base on both sides which in this case is 2.
8/2 = 2g/2
That will cancel the 2 out and will leave you with g on the right side and on the left side would be 4 because simple division (8/2=4)
Your final answer should be g = 4

The x distance is (3--3) = (3+3) 6
and the y distance is (5--5) = (5+5) = 10
We can use the Pythagorean theorem to calculate the hypotenuse, which is the distance from E to D
a^2 + b^2 = c^2
6^2 + 10^2 = c^2
36+ 100 = c^2
136 = c^2
Take the square root of each side
sqrt(136) = sqrt(c^2)
We only take the positive square root since the distance must be positive.
sqrt(4)sqrt(34) = c
2sqrt(34) = c
c is approximately 11.66 units
