Answers

Step-by-step explanation:

why ? you did it right there already.

the numerator is the top part of the fraction, the "counting" part (how many units of a certain type or size are there).

the denominator (the bottom part) is defining the type or size of units described by the fraction.

so, we are adding 4 to the numerator of 2/5, making it (2+4)/5 = 6/5

what do we need to add to the denominator (the bottom part) to make the fraction have the value of 1/2 ?

so, what x would make 6/x = 1/2 ?

6 = x/2

x = 6×2 = 12

so, we need to get 12 in the denominator, where we have currently 5.

therefore, we need to add 12-5 = 7 to it.

so that

6/(5+7) = 6/12 = 1/2

Please answer. I need it to be right.

The lateral area of a cone is 19.2π in2. The radius is 2.4 in. Find the slant height.

Answers

The slant height of a cone with lateral surface are of 19.2π inches squared and radius of 2.4 inches is 8 inches.

Lateral surface area of a cone

The formula for the lateral surface area of a cone is described as follows:

Lateral area = πrl

where

r = base radiusl = slant height

Therefore,

Lateral area = 19.2π inches²

r = 2.4 inches

Lateral area = π × 2.4 × l

19.2π = 2.4πl

divide both sides by 2.4π

l = 19.2π / 2.4π

l = 8 inches

Solve the equation 2×-31=3(×+2)

Answers

Answer:

x=-37

Step-by-step explanation:

First, rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation:

                    2*x-31-(3*(x+2))=0

(2x - 31) -  3 • (x + 2)  = 0

Pulling out like terms

3.1     Pull out like factors :

  -x - 37  =   -1 • (x + 37)

Equation at the end of step

 -x - 37  = 0

Solving a Single Variable Equation:

4.1      Solve  :    -x-37 = 0

Add  37  to both sides of the equation :

                     -x = 37

Multiply both sides of the equation by (-1) :  x = -37

On Saturday, Mark sold 2 7/8 gallons of lemonade. On the same day, Regan sold 2/3 as much lemonade as Mark. How much lemonade, in gallons, did Regan sell? Help

Answers

Answer:

Step-by-step explanation:

The total amount of lemonade Regan sells is 69/16 gallons and this can be determined by using the arithmetic operations.

Given :

   Mark sold 2 7/8 gallons of lemonade.

   Regan sold 2/3 as much lemonade as Mark.

The following steps can be used in order to determine the total amount of lemonade Regan sells:

Step 1 - The arithmetic operations can be used in order to determine the total amount of lemonade Regan sells.

Step 2 - According to the given data, Mark sold 23/8 gallons of lemonade.

Step 3 - Let the total amount of lemonade Regan sells be 'x'.

Step 4 - So, the value of 'x' can be calculated as:

x = 23/8 × 3/2

x = 63/16

The total amount of lemonade Regan sells is 69/16 gallons.

Review the graph of function f(x). On a coordinate plane, a graph has maximum point at open circle (0, 4), and curves down and then repeats with smaller curves at intervals of 2 pi in both the positive and negative x -axis. A point is at (0, negative 2). Which statement identifies and explains Limit of f (x) as x approaches 0? The limit Limit of f (x) as x approaches 0 = –2 because the value of the function at x = 0 is –2. The limit Limit of f (x) as x approaches 0 does not exist because there is an open circle at (0, 4). The limit Limit of f (x) as x approaches 0 = 4 because both the left-hand and right-hand limits equal 4. The limit Limit of f (x) as x approaches 0 does not exist because there is oscillating behavior around x = 0.

Answers

The true statement is that (b) The limit [tex]\lim_{x \to 0} f(x)[/tex] does not exist because there is an open circle at (0, 4).

How to interpret the limit of f(x)?

From the graph of the function (see attachment), we have the following highlight:

There is an open circle at point (0,4), the maximum point of the function f(x) and when x = 0

When there is an open circle in the graph at x = 0, then the function has no limit at this point

This is so because the value is exclusive of the function values

Hence, the limit [tex]\lim_{x \to 0} f(x)[/tex] does not exist because there is an open circle at (0, 4).

What is the value of c if, 2c + 8 = 26 ?

A.
9

B.
42

C.
18

D.
34

Answers

Answer:

Option A

The answer is 9

Step-by-step explanation:

2c + 8 = 26

Subtract 8 from both side we get,

2c + 8 – 8 = 26 – 8

2c = 18

Divide both side by 2 we get,

2c/2 = 18/2

c = 9

Thus, The value of c is 9

2c + 8 = 26
2c = 26 - 8
2c = 18
c = 18 / 2
c = 9

If a system has no solution, how does it look on the graph? What about infinite solutions?

Answers

Hi!

If a graph has no solutions, the lines will be parallel.

Lines have "solutions" when they intersect with eachother. If there are no solutions, the lines will not intersect. Only parallel lines don't intersect.

If a graph has infinite solutions, the lines will be the same.

If a line has infinite solutions, they have to constantly be intersecting. That means the lines will have to be directly on top of each other, meaning they will be the same line.

SEE BELOW for graphs. First graph = NO SOLUTIONS; Second graph = INFINITE SOLUTIONS

Explanation:

No solution:

A graph can only have no solutions if the two lines are parallel. These lines can only be parallel if they have the same slopes, but different y-intercepts. Please check attached graph (1) for illustration of no solution.

Infinitely many solutions:

A graph can have infinitely many solutions if the two lines overlap. This can only happen if both the equations are the same or if simplified, are equivalent. Please check attached graph (2 and 3) for illustration of infinitely many solutions.

write an equation for an arithmic sequence such that t(3)=13 and t(12)=67 HELP ASAP

Answers

Answer:

  t(n) = 1 +6(n -1)

Step-by-step explanation:

The general term of an arithmetic sequence with first term t(1) and common difference d is given by the formula ...

  t(n) = t(1) +d(n -1)

__

Using the two given values  of n and t(n), we can find the unknown parameters.

  13 = t(3) = t(1) +d(3 -1) = t(1) +2d

  67 = t(12) = t(1) +d(12 -1) = t(1) +11d

Subtracting the first equation from the second, we get ...

  (67) -(13) = (t(1) +11d) -(t(1) +2d)

  54 = 9d . . . . simplify

  6 = d . . . . . . divide by 9

Substituting into the first equation gives ...

  13 = t(1) +2(6)

  1 = t(1) . . . . . . . . subtract 12

Using the found values in the equation for the sequence gives ...

  t(n) = 1 +6(n -1)
