Answer:18 1/12
Step-by-step explanation:i first added the whole numbers 12 and 5 to get 17; i then addled 1/4 and 5/6; i did this by finding a common denominator of both fractions and converted them into 6/24 and 20/24; i added them to get 26/24 which simplifies to 1 and 2/24, which equals 1 1/12; i added 1 to 17 and got 18, then added 1/12 to get 18 1/12
The sum of 121/4 and 5 5/6 is found by converting the mixed number to an improper fraction, finding a common denominator, adding the fractions, and simplifying if possible. The final answer is 433/12, which is already in its lowest terms.
The question asks for the sum of the numbers 121/4 and 5 5/6 reduced to the lowest terms. To answer this, we must first convert the mixed number to an improper fraction and then add it to the other fraction. Here's how to do it step by step:
Convert 5 5/6 to an improper fraction: 35/6.
Add 121/4 to 35/6. To do this, find a common denominator, which would be 12 in this case.
Convert both fractions to have the common denominator: 121/4 becomes 363/12, and 35/6 becomes 70/12.
Add the two fractions: 363/12 + 70/12 equals 433/12.
Reduce the fraction if possible. In this case, 433/12 is already in its lowest terms.
Therefore, the sum of 121/4 and 5 5/6 reduced to lowest terms is 433/12.
The quantity, y, varies directly as x. When y=10 x=6
The quantity y is directly proportional to x, indicated by the equation y = (5/3)x, found by determining the constant of proportionality (k = 5/3) given that y=10 when x=6.
Explanation:The problem states that the quantity, y, varies directly as x.
In mathematical terms, this relationship can be represented as y = kx, where k is the constant of proportionality.
Given that when y=10, x=6, we can find k by substituting these values into our formula, yielding 10 = k*6.
Solving for k, we get k = 10/6 or k = 5/3.
Therefore, the equation that describes how y varies directly as x is y = (5/3)x.
This equation tells us that for every unit increase in x, y increases by 5/3 units, illustrating a direct proportionality relationship between the two quantities.
This relationship can be depicted as a straight line through the origin (0,0) on a graph, where k also represents the slope of the line.
Of 300 tickets,240 were sold to sixth grade students what percent of the total number of tickets sold were sold to sixth grade students?
Answer:
80%
Step-by-step explanation:
to find the percentage of tickets sold to sixth grade students
percent sold = [tex]\frac{numbersold}{numberof tickets}[/tex] × 100%
= [tex]\frac{240}{300}[/tex] × 100% = 80%
Answer:
80%
Step-by-step explanation:
To find the percentage sold to sixth graders, take the number sold to sixth graders over the total
percentage to sixth graders = tickets sold to sixth graders/ total tickets
The total tickets are 300
Tickets to sixth graders is 240
Substitute it in
percentage to sixth graders = 240/300
=24/30
=4/5
=.8
Multiply this by 100 to give the percent

A married couple wishing to file their taxes jointly, claim their children, as well as medical expenses must file their taxes using which form?
Answer:
I believe it is a 1040 tax form
Step-by-step explanation:
Final answer:
A married couple should use IRS Form 1040 to file their taxes jointly, claim dependents like children, and deduct medical expenses.
Explanation:
A married couple wishing to file their taxes jointly, claim their children, and deduct medical expenses should use the IRS Form 1040. This is the standard Income Tax Return form for individuals in the US. The Form 1040 allows taxpayers to report their income, claim tax deductions and credits, and calculate the amount of tax owed or refund due.
When filing a joint return, you are also able to claim dependents, which may include children, and report medical expenses that can be deducted if they exceed a certain percentage of your adjusted gross income. While there are different variations, such as 1040A or 1040EZ, the full 1040 form is necessary when claiming detailed deductions such as medical expenses.
What is the equation of a line that is parallel to y= 3 5 x−7 y=35x−7 and passes through (15, 8) (15, 8)
Answer:
The equation of this line would be y = 35x - 517
Step-by-step explanation:
In order to find this equation we must first find the slope of the original line. The original slope (the coefficient of x) is 35, which means the new slope will also be 35 because parallel lines have the same slope. Now, we can use this slope along with the point in point-slope form to find the equation of the line.
y - y1 = m(x - x1)
y - 8 = 35(x - 15)
y - 8 = 35x - 525
y = 35x - 517
The equation of the line parallel to y = 35x - 7 and passing through the point (15, 8) is y = 35x - 517.
Explanation:To find the equation of a line that is parallel to y = 35x - 7 and passes through the point (15, 8), we need to determine the slope of the original line.
Since the given line is in the form y = mx + b, where m is the slope, we can see that the slope of the given line is 35.
Since parallel lines have the same slope, the slope of the line we're looking for is also 35.
Now we can use the point-slope form of a linear equation, which is y - y1 = m(x - x1), where (x1, y1) is a point on the line and m is the slope.
Plugging in the values, we have y - 8 = 35(x - 15).
Expanding and simplifying, we get y - 8 = 35x - 525.
Finally, rearranging the equation, we find the equation of the line is y = 35x - 517.

A rectangle has a length of 6 inches and a width of x inches. The value of the perimeter of the rectangle is equal to the value of the area of the rectangle. Graph a system of linear equations to find x .
The value of x is the point of intersection of the graphs of [tex]\mathbf{P =12 + 2x}[/tex] and [tex]\mathbf{A =6x}[/tex]
The value of x is 3
The given parameters are:
[tex]\mathbf{Length = 6}[/tex]
[tex]\mathbf{Width = x}[/tex]
The perimeter is calculated as:
[tex]\mathbf{P =2 \times (Length + Width)}[/tex]
So, we have:
[tex]\mathbf{P =2 \times (6 + x)}[/tex]
Expand
[tex]\mathbf{P =12 + 2x}[/tex]
The area is calculated as:
[tex]\mathbf{P = Length \times Width}[/tex]
So, we have:
[tex]\mathbf{A =6 \times x}[/tex]
[tex]\mathbf{A =6x}[/tex]
See attachment for the graphs of [tex]\mathbf{P =12 + 2x}[/tex] and [tex]\mathbf{A =6x}[/tex]

Suppose that 216 students attended school one day, and 62 percent of them ate the school's breakfast. How many students ate the school's breakfast that day? Round your answer to the nearest whole number
Answer:
Given the statement:Suppose that 216 students attended school one day, and 62 percent of them ate the school's breakfast.
Total number of students attended school = 216 students.
and 62% of them ate the school breakfast that day.
Now, to calculate the number of students ate the breakfast that day.
Proportion states that the two ratios or fraction are equal.
Let x represents the number of students ate the breakfast that day.
then, by using proportion;
[tex]\frac{62}{100}=\frac{x}{216}[/tex]
Multiply both sides by 216 we get;
[tex]x = \frac{62}{100} \times 216[/tex]
Simplify:
[tex]x = 133.92[/tex]
therefore, the number of students ate the school breakfast that day(to the nearest whole number) is, 134 students.

The table below represents a linear function f(x) and the equation represents a function g(x):
x f(x)
−1 −3
0 0
1 3
g(x)
g(x) = 7x + 2
Part A: Write a sentence to compare the slope of the two functions and show the steps you used to determine the slope of f(x) and g(x).
Part B: Which function has a greater y-intercept? Justify your answer.
Answer:
A) slope of f(x) = 3 , slope of g(x) = 7
B) y intercept of f(x) is 0 and g(x) is 2
So g(x) has greater y intercept
Step-by-step explanation:
Lets find equation of f(x) using the given table
LEts take two points from the table (0,0) (1,3)
[tex]slope = \frac{y_2-y_1}{x_2-x_1} = \frac{3-0}{1-0} = 3[/tex]
we use equation y=mx+b
where m is the slope and b is the y intercept
we got m = 3, we use (0,0) and find out b
y=mx+b
0 = 3(0) + b
so b=0
So equation for f(x)= 3x +0
slope =3 and y intercept = 0
For equation g(x) = 7x +2 , slope = 7 and y intercept = 2
If a line passes through the points (1,3) and (-2,-9), the equation of the line is y-3=4(x-__)
Answer:
y - 3 = 4(x - 1)
Step-by-step explanation:
This is point slope form, which looks like this:
[tex]y-y_{1}=m(x-x_{1})[/tex]
Because a 3 is used for the y value, we know the coordinate point we are using is (1, 3). All we need to do is plug the x value in.
y - 3 = 4(x - 1)

Answer:
C. 105°
Step-by-step explanation:
To find the answer, we can use the method of exterior angle of triangles, which would be <A + <B = <C, in which A and B is any interior angles of triangles and C would be the exterior angle for the remaining angle.
In this case:
45°+60° = 105°
Therefore the answer is C. 105°
Hope it helps!
The measure of the angle x is 105 degrees option (C) is correct.
What is the triangle?In terms of geometry, the triangle is a three-sided polygon with three edges and three vertices. The triangle's interior angles add up to 180°.
We have a triangle shown in the picture.
As we know,
The sum of two interior angles is equal to the exterior angle;
The measure of the angle x:
x = 60 + 45
x = 105 degrees
Thus, the measure of the angle x is 105 degrees option (C) is correct.

So it will take them 18 hours!
Please help me answer this correctly
Answer:
see explanation
Step-by-step explanation:
using A = bh with b = 2x + 1 and h = x + 1, then
(2x + 1)(x + 1) = 28 ← expand factors on left
2x² + 3x + 1 = 28 ( subtract 28 from both sides )
2x² + 3x - 27 = 0 ← in standard form
To factorise, consider the factors of the product of the coefficient of the x² term and the constant term that sum to give the coefficient of the x term
product = 2 × - 27 = - 54 and sum = + 3
The factors are - 6 and + 9
Use these factors to split the middle term
2x² - 6x + 9x - 27 = 0 ( factor first/second and third/fourth terms )
2x(x - 3) + 9(x - 3) = 0 ( take out the factor (x - 3) )
(x - 3)(2x + 9) = 0
equate each factor to zero and solve for x
x - 3 = 0 ⇒ x = 3
2x + 9 = 0 ⇒ x = - [tex]\frac{9}{2}[/tex]
however x > 0 ⇒ x = 3

A rectangular prism with a volume of 2 cubic units is filled with cubes with side lengths of 1/4 unit. How many 1/4 unit cubes does it take to fill the prism
Answer:
128
Step-by-step explanation:
Method A.
The volume of the prism is 2 cubic units.
Each cube has side length of 1/4 unit.
The volume of each cube is (1/4)^3 cubic unit.
The volume of each cube is 1/64 cubic unit.
To find the number of cubes that fit in the prism, we divide the volume of the prism by the volume of one cube.
(2 cubic units)/(1/64 cubic units) =
= 2/(1/64)
= 2 * 64
= 128
Method B.
Imagine that the prism has side lengths 1 unit, 1 unit, and 2 units (which does result in a 2 cubic unit volume.) Since each cube has side length 1/4 unit, then you can fit 4 cubes by 4 cubes by 8 cubes in the prism. Then the number of cubes is: 4 * 4 * 8 = 128
Answer:
128 cubes.
Step-by-step explanation:
Volume of each cube = (1/4)^3 = 1/64 cubic units.
Number of cubes that will fill the prism
= 2 / 1/64
= 2*42
= 128 answer
