If y varies inversely as x and y is 6 when x is 12 what is x when y is 14.4
Answers
y=k/x
k: It is the constant of variation or constant of proportionality.
2. So, keeping this on mind, you must calculate the value o the constant of variation "k", with the values given in the problem. Then, you have:
k=yx
k=(6)(12)
k=32
3. Now, you can apply the equation y=k/x and clear the "x" to find its value:
yx=k
x=k/y
k=32
y=14.4
4. Then, you have:
x=32/14.4
5. Therefore, the answer is:
x=2.22

The center of a circle is (4, 6), and an endpoint of a diameter is (2, 5). What is the other endpoint of the diameter?
Answers
1. if the point (4;6) is the centre of the circle and the point (2;5) is the first endpoint of its diameter, then point (4;6) is the middle point of the diameter (it means that is the middle between the 1st and the 2d endpoints of diameter).
2. using the property described above:
for x of the 2d endpoint of the diameter: x=4*2-2=6;
for y of the 2d endpoint of the diameter: y=6*2-5=7.
answer: (6;7)
Answer:
(6,7)
Step-by-step explanation:
The center of a circle is (4, 6), and an endpoint of a diameter is (2, 5)
Since center is the mid point of two end points of diameter .
So, we will use mid point formula
[tex](x,y)=(4,6)[/tex]
[tex](x_1,y_1)=(2,5)[/tex]
Mid point formula : [tex]x =\frac{x_1+x_2}{2}[/tex] and [tex]y =\frac{y_1+y_2}{2}[/tex]
Substitute the values
[tex]4 =\frac{2+x_2}{2}[/tex] and [tex]6 =\frac{5+y_2}{2}[/tex]
[tex]8 =2+x_2[/tex] and [tex]12 =5+y_2[/tex]
[tex]6=x_2[/tex] and [tex]7=y_2[/tex]
Thus [tex](x_2,y_2)=(6,7)/tex]
Thus the other endpoint of the diameter is (6,7)

Mora ate 8.5 Containers of Yogurt one week. Each Container Held 5.4 Ounces Of Yogurt . HOW Many Ounces Of Yogurt Did she eat in all
Answers
Final answer:
Mora ate a total of 45.9 ounces of yogurt after consuming 8.5 containers, with each container holding 5.4 ounces.
Explanation:
The student asked how many ounces of yogurt Mora ate after consuming 8.5 containers, with each container holding 5.4 ounces. Mora ate 8.5 containers of yogurt, with each container holding 5.4 ounces of yogurt. To calculate the total amount of yogurt consumed, we multiply the number of containers by the amount of yogurt each container holds.
To solve this, simply calculate 8.5 containers × 5.4 ounces/container = 45.9 ounces of yogurt in total. This is the total amount of yogurt Mora ate during that week.

X^3-64=0
Solve the equation
Answers
We want to solve for x. Start by getting x by itself on one side.
We can do this by adding 64 to both sides of the equation.
x^3 = 64
Now, to get rid of the 3rd power that x is raised to, we can raise both sides to the 1/3 power
(x^3)^1/3 = 64^1/3
(x^3)^1/3 is the same as x
So x = 64^(1/3) and 64^(1/3) = 4
So x = 4 :)

One side of a square flower bed is 22 feet long. How many plants are needed if they are to be spaced 22 inches apart around the outside of the bed?
Answers
12*4 = 48 plants are needed for the outside border.
To find out how many plants are needed, we calculate the perimeter of the square flower bed, convert that to inches, and then divide by the spacing of the plants. In this case, about 48 plants would be needed.
Explanation:This problem can be solved using the properties of a square and unit conversion. Since a square has four equal sides and each side of the square flower bed is 22 feet long, the total perimeter of the flower bed would be calculated as 22 feet * 4, which is 88 feet. Next we need to convert these feet to inches since the plants are spaced 22 inches apart. There are 12 inches within a foot, so 88 feet equals 1,056 inches (88*12).
Once you have the total length in inches, you can determine the number of plants by dividing the total length in inches by the distance each plant is to be spaced. Thus, 1,056 inches divided by 22 inches gives us approximately 48 plants.
So, if you want to space your plants 22 inches apart around a square flower bed where each side is 22 feet, you will need 48 plants.

A pound of popcorn is popped for a class party. The popped corn is put into small popcorn boxes that each hold 130 popped kernels. There are 1,450 kernels in a pound of unpopped popcorn. If all the boxes are filled except for the last box, how many boxes are needed and how many popped kernels are in the last box? Please explain how you get the answer
Answers
1450/130 is 11.15 so You round up and need 12 boxes (because you can’t have .15 of a box) so you get the 11 boxes and multiply by how much it can hold (130) and get 1430 which is 20 short of 1450 so 20 would be in the last box .
12 boxes are needed in all.
Last box will contain only 20 kernels.
Step-by-step explanation:Given is :
The popped corn is put into small popcorn boxes that each hold 130 popped kernels.
There are 1450 kernels in a pound of un popped popcorn.
If all the boxes are filled except for the last box, then how many boxes are needed?
Number of boxes = Total number of kernels/Number of kernel in each box
=> [tex]\frac{1450}{130}= 11.15[/tex]
Therefore, a total of 11+1 = 12 boxes are needed as 11.15 is more than 11.
And the last box will contain = [tex]1450-1430=20[/tex] kernels.
Therefore, the last box will have 20 kernels.

In the Chang family's budget, 0.6% of the expenses are for internet service. What is the fraction of the family's expenses is for internet service? Write the fraction in the simplest form.
Answers
You probably know intuitively that 100% is one whole, for example. But it's also the same as saying [tex] \frac{100}{100} [/tex]. Likewise, 67%, for instance, is actually [tex] \frac{67}{100} [/tex].
In this case, you can write [tex] \dfrac{0.6}{100}[/tex]. But you may realize that you shouldn't have a decimal in a fraction. For every number after the decimal, you multiply the whole thing by a corresponding power of ten. Here, you write [tex] \dfrac{0.6}{100} * \dfrac{10}{10} = \dfrac{6}{1,000} [/tex]. Since 10/10 is equal to 1, we aren't changing anything (Identity Property). If you had 0.06/100, you would multiply by 100/100, and so on...
So, now we have [tex] \dfrac{6}{1000} [/tex]. Our next step is to simplify. The greatest common factor of these two numbers is 2, we rewrite as [tex] \dfrac{3}{500} [/tex] to put it into simplest form. And that's all there is to it.
A cruise boat travels 48 miles Downstream in 2 hours and returns Upstream in 3 hours. Find the speed of the boat in still water and the rate of the Stream.
Answers
The downstream speed will be x+y, the upstream speed will be x-y.
but:
distance=speed*time
therefore; as the boat travels in 2 hours downstream we shall have:
2(x+y)=48......i
and as the boat travels upstream we shall have:
3(x-y)=48........ii
simplifying i and ii we get:
x+y=24....iii
x-y=16....iv
adding the above iii and iv we get
2x=40
x=40/2=20
substituting x=20 into iii we obtain:
20+y=24
y=24-20
y=4
so the speed of the boat in still waters is 20 miles per hour
the rate of the stream is 4 miles per hour
Final answer:
The speed of the cruise boat in still water is 20 mph and the rate of the stream is 4 mph.
Explanation:
The student is asking about a problem related to the rate of the boat in still water and the rate of the stream, given the times it takes to travel downstream and upstream. To solve this, we can use the following steps:
Let the speed of the boat in still water be b mph and the rate of the stream be s mph.Downstream, the effective speed is b + s and upstream it's b - s.Using the formula distance = speed imes time, we have two equations based on the given information: 48 miles = (b + s) imes 2 hours for downstream and 48 miles = (b - s) imes 3 hours for upstream.Solve the two equations simultaneously to find the values of b and s.Let's solve the equations:
48 = 2(b + s) => 24 = b + s48 = 3(b - s) => 16 = b - sAdding both equations:
24 + 16 = (b + s) + (b - s) => 40 = 2b => b = 20 mph (boat speed in still water)Subtracting the upstream equation from the downstream equation:24 - 16 = (b + s) - (b - s) => 8 = 2s => s = 4 mph (rate of the stream)Therefore, the speed of the boat in still water is 20 mph and the rate of the stream is 4 mph.
what is the simplified form of 3a4b-2c3?
Answers
The expression 3a4b-2c3 is already in its most simplified form because they are not like terms, thus cannot be combined.
Explanation:The given expression 3a4b-2c3 cannot be simplified further because it consists of variable components. Each of these components -- 3a, 4b, and 2c3 -- represent distinct and separate entities in the equation. Unlike in some mathematics problems, these components cannot be combined or simplified because they are not like terms. In algebra, like terms are terms that contain the same variables and powers. So only if the given equation was 3a + 2a or 4b - 3b, then they could be combined. But as it stands, 3a4b-2c3 is already in its most simplified form.
