what is the answer to this equation 21 x ___=7

The fraction that is is 45 centimeters of 100 meters is: 9/20.

To find the fraction of 1 meter that 45 centimeters is, make the units uniform.

That is, convert 1 meter to centimeters.

100 centimeters = 1 meter

Therefore, we would find what fraction is 45 centimeters of 100 centimeters (1 meter):

45 centimeters of 100 centimeters (1 meter) = 45/100

Reduce the fraction to its simplest form

45/100

45 divided by 5 = 9

100 divided by 5 = 20

Therefore, we would have:

45/100 = 9/20

In summary, the fraction that is is 45 centimeters of 100 meters is: 9/20.

The total amount payable at the end of 4 years is 406

In this given sum we are provided with the values of principal , rate of interest , and the number of years , we are asked to calculate the amount payable after 4 years that is the matured amount which is calculated with the addition of the principal amount and the simple interest. For that we had to first find out the amount of interest and then we need to add that with the principal amount to get the matured amount or the amount that is payable at the end of 4 years.

here we have to apply the formulla of simmple interest :

(principal × rate of interest × no. of years )/ 100

In the given sum principal (p) = 350 , rate of interest (r) = 4% pa , no. of years (n) = 4

Simple interest = pnr/100

= (350 × 4 × 4)/100  = 56

Answer:

the answer

Step-by-step explanation:

Answer:

Step-by-step explanation:

Slope intercept form is y=mx+b

Where m is the slope

general form is ax+by+c=0

this means, 2 is b

3x-2y=-16

y=3/2x+8

Now

subtract ax from both sides

3x -2y-3x= -16-3x

-2y=-16-3x

Subtract C from both sides

-2y=-3x+-16

divide both sides by b

y=-3/-2 x -16/-2

the slope is given by -a/b and the y intercept is given by -c/b

simplify

y=3/2x+8

The value of the n in the mean value is 1.

According to the statement

We have to find that the value of the n in the mean.

So, For this purpose, we know that the

Mean is the simple mathematical average of a set of two or more numbers.

From the given information:

The mean number of hours is 1.75

Then

We are given that

Day       Hours

Sunday    0

Monday   1.5

Tuesday    2.5

Wednesday  2.5

Thursday       3

Friday            0

Saturday       n

Mean number of hours of  study per day=1.5

Then

Total number of days=7

Using the formula:

Mean = sum of data / Total number of the data points

1.5 = 9.5+n / 7

1.5*7 = 9.5+n

10.5 =  9.5+n

n =  10.5 - 9.5

n = 1.

Answer:

  C.  1889

Step-by-step explanation:

Given fixed weekly costs of $3778 and a variable cost per handle of $1, you want to know how many handles must be produced weekly for sale at $3 each to break even.

The "contribution margin" of each handle is the difference between its variable cost and its selling price:

  $3 -1 = $2

The enterprise will break even when the sum of contribution margins is equal to the fixed costs. If h is the number of handles produced and sold, then to break even, we must have ...

  2h = 3778

  h = 1889

1889 handles must be molded weekly to break even.

__

Additional comment

You get the same result if you write the profit equation and solve for the number of handles that makes profit be zero.

  profit = revenue -cost

  0 = (3h) -(3778 +1h)

  3778 = 2h . . . . . as above

  1889 = h

The absolute value function of the given expression is g(x) = 3*Ix + 2I.

The absolute value function is often assumed to provide the number's distance from zero on a number line. Algebraically, the output is really the value without respect to sign regardless of what the input value is.

Let's define transformations in broad strokes.

A vertical stretch with scale factor A is denoted by:

g(x) = A*f(x)

A vertical shift in A units is denoted by:

g(x) = f(x) + A

If A is positive, the shift is positive; if A is negative, the shift is negative.

A horizontal shift in A units is denoted by:

g(x) = f(x - A)

If A is greater than zero, the shift is toward the right.

The shift  to the left if A is negative.

Then we begin with the maximum value parental function f(x) = IxI.

"The graph of both the absolute value parent function has been stretched vertically by a factor of three."

we can start with:

g(x) = 3*f(x)

"then shifted two units left"

g(x) = 3*f(x - (-2))

and since f(x) = IxI, they have:

g(x) = 3*Ix + 2I

the absolute value function of the given expression is g(x) = 3*Ix + 2I.

Percent of vipers is 20% and its degree is 72 degrees.

Percent of colubrids is 46% and its degree is 165.60 degrees.

Percent of elapids is 18% and its degree is 64.80 degrees.

Percent of giant snakes is 16% and its degree is 57.60 degrees.

The percent can be calculated as follows:

Percent of vipers = (Number of vipers / Total number of snakes) * 100 = (10 / 50) * 100 = 0.20 * 100 = 20%

Percent of colubrids = (Number of colubrids / Total number of snakes) * 100 = (23 / 50) * 100 = 0.46 * 100 = 46%

Percent of elapids = (Number of elapids / Total number of snakes) * 100 = (9 / 50) * 100 = 0.18 * 100 = 18%

Percent of giant snakes = (Number of giant snakes / Total number of snakes) * 100 = (8 / 50) * 100 = 0.16 * 100 = 16%

The degrees can be calculated as follows:

Degree of vipers = Percent of vipers * 360 = 20% * 360 = 72 degree

Degree of colubrids = Percent of colubrids * 360 = 46% * 360 = 165.60 degree

Degree of elapids = Percent of elapids* 360 = 18% * 360 = 64.80 degree

How to calculate a resultant point's coordinates using the weighted averages method?

We must locate the third point by applying a method based on a weight average-like formula after finding the coordinates of two points on the Cartesian plane:

P(x, y) = (2 / 7) * A(x, y) + (5 / 7) * B(x, y)

P(x, y) = (2 / 7) * (- 4, 2) + (5 / 7) * (3, - 6)

P(x, y) = (- 8 / 7, 4 / 7) + (15 / 7, - 30 / 7)

[tex]59 + 3x < 75[/tex]

Step-by-step explanation:

We know from the question that Fatoumata pays a flat cost of $59 per month and $3 per gigabyte.

If we consider [tex]x[/tex] to be the number of gigabytes she uses in a month, then her bill every month can be represented by the following expression:

[tex]59 + 3x[/tex] .

We are told that the bill has to be kept under $75. Therefore:

[tex]59 + 3x < 75[/tex]

This inequality can be used to solve for [tex]x[/tex], and so we can use it to find the maximum number of gigabytes she can use while keeping the bill under $75.

The inequality for the maximum number of gigabytes Fatoumata can use while staying within her budget will be equal to $59 + $3(x) < $75.

Mathematical expressions with two algebraic symbols on either side of the equal (=) sign are called equations.

This relationship is illustrated by the left and right expressions being equal to one another. The left-hand side equals the right-hand side is a basic, straightforward equation.

As per the given information in the question,

Price of cell phone plan per month = $59

The price per gigabyte = $3

Then, the equation as per the statement will be,

$59 + $3(x)

Here, x is the number of gigabytes used in a month.

So, the inequality will be,

$59 + $3(x) < $75
