Answer:
The mother is wrong
Step-by-step explanation:
What we do here will be to add the fractions of the cakes that we have
Mathematically, that will be;
14/12 + 5/6 = 24/12 = 2
This means that the mother is wrong and the cakes can actually be made into 2

Answer:
-0.29629629629 or -0.3
Step-by-step explanation:
first do (-2/3)*(-4 1/2) which is 3
then divide (-8/9) by 3 and you get -0.29629629629 which can be rounded to -0.3
The Answer will be -8 using fraction operation.
What is a fraction?If the numerator is bigger, it is referred to as an improper fraction and can also be expressed as a mixed number, which is a whole-number quotient with a proper-fraction remainder.
Any fraction can be expressed in decimal form by dividing it by its denominator. One or more digits may continue to repeat indefinitely or the result may come to a stop at some point.
First solve the 2nd part which is
[tex]\frac{-2}{3}*-4\frac{1}{2} \\=3[/tex]
Now -8/3 * 3 = -8
Hence the answer for the given question will be -8.

Vocabulary Explain why each relationship is not linear PLEASE HELP ASAP
Answer:
11) This table is not linear because linear tables and graphs have a constant rate of change, so in the table, we can see that the x-value goes up by 1 every time but the y-value is not constant. It goes up by 2 from 4.5, 6.5, 8.5, but then at 8.5 to 11.5, it went up by 3 which means that it's not a constant rate of change and is not linear.
12) This table is not linear because linear tables and graphs have a constant rate of change, so in the table, we can see that the x-value goes up by 2 every time but the y-value is not constant. It went down by 14 then 16 and 18. All these numbers and different which means that the table does not have a constant rate of change and is not linear.
Step-by-step explanation:
Always remember that linear tables, graphs, etc have a constant rate of change.

5 AB is the diameter of a circle whose center is the point (4,-3). If the coordinates of A are (-1,5), Find AB>
Given:
AB is the diameter of a circle whose center is the point (4,-3).
Coordinates of A are (-1,5).
To find:
The measure of AB.
Solution:
Let point O(4,-3) be the center of the circle.
Then, OA is the radius of the circle.
We know that, diameter of a circle is twice of its radius.
So, [tex]AB=2(OA)[/tex] ...(i)
Distance formula:
[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Using distance formula, the distance between O and A is
[tex]OA=\sqrt{(-1-4)^2+(5-(-3))^2}[/tex]
[tex]OA=\sqrt{(-5)^2+(5+3)^2}[/tex]
[tex]OA=\sqrt{25+(8)^2}[/tex]
[tex]OA=\sqrt{25+64}[/tex]
[tex]OA=\sqrt{89}[/tex]
Now, using (i), we get
[tex]AB=2(OA)[/tex]
[tex]AB=2(\sqrt{89})[/tex]
[tex]AB=2\sqrt{89}[/tex]
Therefore, the measure of AB is [tex]2\sqrt{89}[/tex] units.

The radius of Earth is 6,371.0 kilometers and the radius of Earth's Moon is 1,737.5 kilometers. What is the approximate difference in the circumferences, in kilometers, of Earth and Earth's Moon? Round your answer to the nearest tenth of a kilometer.
Answer:
Step-by-step explanation:
Circumference of a circle is expressed as;
C = 2πr
r is the radius
Given
radius of Earth r1 = 6,371.0 kilometers
the radius of Earth's Moon r2 = 1,737.5 kilometers
The difference in their circumference will be expressed as;
C = 2π(r1-r2)
C = 2π(6371.0-1737.5)
C = 2π(4633.5)
C = 2(3.14(4633.5))
C = 29,098.38km
C = 29,098.4
Hence the difference in their circumference to the nearest km is 29,098.4km
Answer:
We calculate for the circumferences of Earth and moon by using the equation,
C = 2πr
For Earth,
C = 2π(6371 km) = 40030.2 km
For Moon,
C = 2π(1737.5 km) = 10917.0 km
The difference between the two circumferences is 29113.2 km approximately.

Answer:
The lower right table
Step-by-step explanation:
The table of that's the right answer consists of f(x) and x points that when plugged into the equation make the equation equal.
Let's go through each of the tables to check.
Upper Left Table:
(Remember that f(x) and y are interchangeable)
- Let's plug in the first paired set (0,6) into the equation
[tex]y = -2x + 6 \\6 = -2(0) + 6\\6 = 6[/tex]
So, this one seems right so far. It also let's us eliminate some answers!
The upper right and lower left tables can't be right because in order for the equation to be equal, f(x) has to be 6 when x equals 0
Let's plug more paired sets into the equation from the upper left table
[tex]y = -2x + 6\\10 = -2(2) + 6 \\10 = -4 + 6 \\10 = 2[/tex]
This doesn't work so let's check to see if the lower right table is correct!
[tex]y = -2x + 6 \\2 = -2(2) + 6\\2 = -4 + 6\\2 = 2[/tex]
Since the equation is equal, this has to be the right answer!
Hope this helps!!

Please solve for y P=2x+2y+4
Answer:
Step-by-step explanation:
P=2x+2y+4
y=p/2-x-2
The equation can represent as y = P/2 - x - 2 after solving for y if the equation is P = 2x + 2y + 4.
What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
It is given that:
Solve for y P=2x+2y+4
From the data given in the question:
The linear equation is:
P=2x+2y+4
To solve for make the subject as y:
2y = P - 2x - 4
y = (1/2)[P - 2x - 4]
Or
y = P/2 - x - 2
Thus, the equation can represent as y = P/2 - x - 2 after solving for y if the equation is P = 2x + 2y + 4.

Jon owns a hamburger stand. He creates a function for the number of dollars in his register (d) in relation to the number of hamburgers (h) he sells. d=3h+8 How much does he charge for a hamburger? 1 dollar 1 dollar 2 dollars 2 dollars 3 dollars 3 dollars 8 dollars
Answer:
The amount charged for a hamburger is $11
Step-by-step explanation:
The function relating the amount d charged with the number of hamburgers is;
d = 3h + 8
The amount charged for a hamburger can be calculated by substituting the value 1 for h
Thus, we have;
d = 3(1) + 8 = $11

y= -2x- [tex]\frac{2}{3}[/tex]
Step-by-step explanation:
3y+2=-6x
3y=-6x-2
y= [tex]\frac{-6}{3}[/tex]x - [tex]\frac{2}{3}[/tex]
y= -2x - [tex]\frac{2}{3}[/tex]
You isolate for y in this example by moving the 2 to the other side and then dividing the -6x and -2 by 3 to get the y by itself.
