Simplify 4/5/10. Give the answer in simplest form.​

Answer:

310

Step-by-step explanation:

189+122=311

(311 rounded to the nearest ten is 310.)

The volcano is growing larger by 1 cm/year.

In order to determine if the volcano is growing or wearing down, determine the cm that the volcano wears down each year. To do this, we would be dividing the total cm the volcano wears down by the number of years.

Division is the process of grouping a number into equal parts using another number. The sign used to denote division is ÷.

The cm the volcano wears down each year = 20 cm / 5 = 4cm

10 / 2 = 5cm

5cm - 4cm = 1 cm

This means that the volcano is growing at 1 cm per year.

The center of the circle is (3, -1) and the radius  of the circle is 4

The equation of the circle is given as

x^2 + y^2 - 6x + 2y = 6

The above equation is the standard equation of a circle

Start by converting the above standard equation of a circle to a form other than the standard equation

Using a graphing calculator, we have the following form

(x - 3)^2 + (y + 1)^2 = 4^2

The equation of a circle is represented as

(x - h)^2 + (y - k)^2 = r^2

Where the center is

Center = (h, k)

So, we have

(h, k) = (3, -1)

This means that

Center = (3, -1)

Hence, the center of the circle is (3, -1)

In (a), we have

Using a graphing calculator, we have the following form

Given: [tex]\textsf{-5/6x = -10/3}[/tex]

Find:  [tex]\textsf{The value of x}[/tex]

Solution: In order to get the value of x we must multiply both sides by -6/5 to help cancel the coefficient on the left side to leave x by itself.

Multiply both sides by -6/5

Therefore, the value of the unknown variable x is 4.

The products that have 240 as a partial product are 3 x 3,388 and 6 x 4,345

The partial product is given as

240

Express 240 as a product of its factors

So, we have

240 =  1 * 240

240 =  2 * 120

240 =  3 * 80

240 =  4 * 60

240 =  5 * 48

240 =  6 * 40

240 =  9 * 30

Next, we test the options

3 x 3,388

Express all values other than the ten-place value as 0

3 x 0080

Evaluate the product

3 x 0080  = 240

The equation 4y = -4x + 2³​ is a linear function

A linear function can be explained as an algebraic equation, whose every  term is either a constant or the product of a constant and a variable (raised to the first power only).

The equation 4y = -4x + 2³​ is a linear function since both variables x and y meet the criteria, and both constants a and b do comply with rules as well

The exponent of x is 1, that is, it is raised to the first power only and the equation follows the definition of a function: for each input (x) there is only one output (y). The graph of any linear function in one variable  is always  a straight line.

Geometric sequence with a common ratio of 1/3

Step-by-step explanation:

Each term is 1/3 of the previous term:
First term is : 162
Second term: 162 x 1/3 = 162/3 = 54
Third term : 54 x 1/3 = 54/3 = 18

and so on

The ratio of a term to its previous term is therefore 1/3 and this is called a common ration

This kind of sequence where each term is a multiple (1/3) of the previous term is called a geometric sequence

Answer: x=-7, y=0

Step-by-step explanation:

You can see just by the set up that the x values cancel each other out without you having to do anything(-2x+2x=0). Because of this, you can add the two equations to eliminate the x values.

-2x+8y = 14

2x+8y= -14    -------->   16y=0

When you isolate the variable, you get y=0. Now you can choose one of the original equations and substitute 0 into the y value.

-2x+8y = 14 ---> -2x+8(0) = 14 ----> -2x+0 = 14 ---> -2x=14

When you divide both sides by -2, you get x=-7.

Answer:

Step-by-step explanation:

Given square TUVW, you want the perimeter and area of square T'U'V'W' after it has been dilated by a factor of 5/2 and translated by (0, -8).

Counting grid squares, or reading coordinates, we find the length of a side of square TUVW to be 8 units. Then the perimeter is ...

  P = 4s = 4·8 = 32 . . . . units

After dilation, the perimeter of the square is the preimage value multiplied by the dilation factor.

 perimeter of T'U'V'W' = (5/2)(perimeter of TUVW) = (5/2)(32 units)

  perimeter of T'U'V'W' = 80 units.

The area is the square of the side length. The side length of T'U'V'W' is ...

  s' = (5/2)(8) = 20 . . . . units

Then the area is

  A' = (s')² = (20 units)² = 400 units²

area of T'U'V'W' is 400 units².

Additional comment

Translation is a rigid transformation. It does not change the dimensions, so does not change the perimeter or area of the dilated square.

Answer:

x < - 9 or x > 1

Step-by-step explanation:

inequalities of the type | x | > a have a solution of the form

x < - a or x > a

| 2x + 8 | > 10 is of this type , then

2x + 8 < - 10 or 2x + 8 > 10 ( subtract 8 from both sides of each inequality) )

2x < - 18 or 2x > 2 ( divide both sides of each by 2 )

x < - 9 or x > 1

The percentage of students at the college have a GPA between 2.3 and 3.3 is C. 68.26%.

How far is 2.3 from 2.8. This will be:

= (2.3-2.8) = -0.5

That means 2.3 is one standard deviation to the left of the mean.

How far is 3.3 from 2.8? This is (3.3-2.8) = 0.5

That means 3.3 is one standard deviation to the right of the mean.

According to the empirical rule 68% of normally distributed data is within 1 standard deviation of the mean.
