A city has a 5% sales tax. What is the constant of proportionality?

Answers

Answer 1

Answer: 0.05

Step-by-step explanation:

The equation is k = y/x, which is a constant change rate

Take 5 divided by 100 = 0.05

5% = 0.05

So the constant of proportionality is 0.05

Five times the sum of some number plus 3 is
equal to 9 times the number minus 9.

Answers

Five times the sum of some number plus 3 is equal to 9 times the number minus 9.

5 (x + 3) = 9x - 9

expand left side:

5x + 15 = 9x - 9

subtract 15 from both sides:

5x + 15 - 15 = 9x - 9 - 15

5x = 9x - 24

subtract 9x from both sides:

5x - 9x = 9x - 24 - 9x

-4x = -24

divide both sides by -4:

-4x/(-4) = -24/(-4)

A land developer is splitting up 1.31 hectares of land to form 5 identical properties. What size will each property be?

Answers

Answer:

0.262 hectares

Step-by-step explanation:

To find the size of each property, you need to divide the total area of the land by the number of properties. In this case, the total area of the land is 1.31 hectares, and it is being divided into 5 properties, so the size of each property is:

Property size = 1.31 hectares / 5 properties = 0.262 hectares/property

Therefore, each property will be 0.262 hectares in size.

Samantha visited Forager Family Farm yesterday. She picked a bucket of fresh berries in
the field. She also got 2 pints of pre-picked berries at the farm stand because they were
overripe and perfect for making jam. The farm charges $3 a pint for berries, regardless of
whether they're fresh-picked or pre-picked. Samantha paid $24 in all.
Which equation can you use to find f, the number of pints of fresh berries Samantha
picked?
2(f+ 3) = 24
3f + 2 = 24
Submit
3(f+ 2) = 24
2f + 3 = 24

Answers

3( f + 2) = 24 that is the answer

The solution is Option C.

The number of pints of fresh berries is 6 pints and is calculated by the equation 3 ( f + 2 ) = 24

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the number of pints of fresh berries be represented as f

Now , the number of pints of berries Samantha got initially = 2 pints

So , the total number of berries Samantha got = f + 2

The cost of 1 pint of berries = $ 3

The total amount Samantha paid for the berries = $ 24

Now , the equation will be

Total amount Samantha paid for the berries = cost of 1 pint of berries x ( total number of berries Samantha got )

Substituting the values in the equation , we get

24 = 3 ( f + 2 )   be equation (1)

On simplifying the equation , we get

Divide by 3 on both sides of the equation , we get

f + 2 = 8

Subtracting 2 on both sides of the equation , we get

f = 6 berries

Hence , the equation is 3 ( f + 2 ) = 24

Libby receives pay of $734 which she deposits in her cheque account. She then writes out cheques for $558 and $453. If her account Is now $78 overdrawn what was her cheque account balance before she received her pay?

Answers

Answer: $355

Step-by-step explanation:

First, find the total of cheques she writes out by taking 558 + 453 = $1011

Then add 78 to it because she is overdrawn by $78 at the end, so we now have $ 1089.

Then we take 1089 - 734 = $355

So, her cheque account balance before she received her pay was $355

prove that there are no solutions in integers x and y to the equation 2x2 + 5y2 = 14.

Answers

The quadratic equation does not have solutions where both x and y are integers.

How to prove that there are no integer solutions for the equation?

Here we have the following quadratic equation:

2x^2 + 5y^2 = 14

We want to check that we can't solve this equation with x and y integers, to see that, we can start by isolating one of the variables:

2x^2 + 5y^2 = 14

5y^2 = 14 - 2x^2

y^2 = (14 - 2x^2)/5

y = ±√((14 - 2x^2)/5)

Now, trivially:

(14 - 2x^2)/5

Is not an integer for any integer value of x, and this happens because 5 is not a factor of 14, thus, for any integer value of x the value of y that we get is non integer, then there aren't two integers that solve the quadratic equation.

A quare that ha 21 ha a the perimeter. Find the ide length of the quare and the area of the quare. HELP PLEASE

Answers

Answer:

area = 27.5625, side length = 5.25

Step-by-step explanation:

21 is the perimeter of a square (given). We know a square has 4 equal sides, so 4s = p, where s is the side length and p is the perimeter of a square. Thus: 4s = 21 → s = 5.25

We also know that a square has a = s², where s is the side length and a is the area. Thus, a = 5.25² → a = 27.5625

Two payment options to rent a car: You can pay $25 a day plus 5¢ a mile (Option A) or pay $15 a day plus 30¢ a mile (Option B). For what amount of daily miles will option B be the cheaper plan?

Answers

First, let's define some variables:

D = number of daily miles
A = total cost of Option A
B = total cost of Option B

We can express the total cost of Option A and Option B in terms of D as follows:

A = $25 + 0.05D
B = $15 + 0.30D

To find the amount of daily miles for which Option B is cheaper, we need to set A equal to B and solve for D:

$25 + 0.05D = $15 + 0.30D
0.25D = $10
D = 40 miles

Therefore, Option B is cheaper for 40 daily miles or less.

Option a) The similar triangles are ⇒ ΔADE ≅ ΔABC

Option b) ∠ADE = ∠ABC

According to the figure given in the question,

We can observe that there are two right-angled triangles present and we have to derive the similarities between them

Let one triangle be = ΔADE

Another triangle be = ΔABC

Let us consider the angle arc at point A,

We can conclude that ⇒ ∠BAC = ∠DAE ( according to the property of similar angles )

∠ADE = ∠ABC ( by the similar 90° angles )

and both angles are making a total of 180°

So, from the above expressions, we can say that,

Answers

The system of equations, 2x − 7y = −15 and 4x − 14y = 30, has no solution.

What is the Solution to the System of Equations?

To find the solution to the system of equations, we can plot the line of the two equations on a graph, then find the coordinate of the point where both lines of the equations intersect each other.

Alternatively, we can solve simultaneously as shown below:

2x − 7y = −15 --> eqn. 1

4x − 14y = 30 --> eqn. 2

Rewrite eqn. 1:

2x − 7y = −15

-7y = -15 - 2x

y = 15/7 + 2/7*x

Substitute the value of y into eqn. 2:

4x − 14(15/7 + 2/7*x) = 30

4x - 30 - 4x = 30

0 - 30 = 30

0 - 30 + 30 = 30 + 30

0 = 60 [not true]

This means that the system has no solution. If we graph both lines, the two lines of the equations will not intersect each other at any point.

y-b=m(x-a) i being try to do it but i cant

Answers

Explanation:

The equation y - b = m(x - a) is a mathematical formula that describes the relationship between the x and y coordinates of a point on a line. The equation is called "point-slope form" because it uses the coordinates of a point on the line (point a) and the slope of the line (m) to describe the line.

The equation has three parts: y, b, and m(x - a).

The y part of the equation represents the y-coordinate of a point on the line. This value can change depending on the x-coordinate of the point.

The b part of the equation is the y-coordinate of a known point on the line. This value is fixed and does not change.

The m(x - a) part of the equation represents the slope of the line and the x-coordinate of the known point on the line. The slope is represented by m, and the x-coordinate of the known point is represented by a.

To use the equation to find the y-coordinate of a point on the line, you first need to know the x-coordinate of the point and the values of b, m, and a. Then, you can substitute these values into the equation and solve for y.

For example, if the x-coordinate of a point on the line is 5, the y-coordinate of a known point on the line is 2, the slope of the line is 3, and the x-coordinate of the known point is 1, then the y-coordinate of the point can be calculated as follows:

y - 2 = 3(x - 1)

y = 3x - 3 + 2

y = 3(5) - 3 + 2

y = 15 - 3 + 2

y = 14

Therefore, the y-coordinate of the point with x-coordinate 5 is 14.

In summary, the equation y - b = m(x - a) is a mathematical formula that describes the relationship between the x and y coordinates of a point on a line. The equation uses the coordinates of a known point on the line and the slope of the line to describe the line, and you can use it to find the y-coordinate of a point on the line if you know the x-coordinate of the point and the values of b, m, and a.
