Rewrite The Equation So That It Does Not Have Fractions, Without Using Decimals (please Answer Quickly)

Answers

Answer 1

Answer:

should be
38 = 9x

Step-by-step explanation

multiply both sides with the least common denominator of the denominator of the fraction (the number below the line).
of the numbers 4 and 6, the least common denominator is 12.
so multiply both sides of the equation by 12.
you will have
12 * (4 - 3/4 x) = 12 * 5/6
simplify and you will get
48 - 9 x = 10

and you can even more simplify it to 9x = 38 or 38 = 9x

Answer 2
Multiply through by 12 to clear the fractions
48 _ 9x = 10

write and solve a system of linear equations to find the values of $x$ and $y$ . a quadrilateral. the angles of the quadrilateral are 5x degrees, (4y minus 2 )degrees, (13x plus 10 )degrees, and 10y degrees.

Answers

As per the angle sum property of quadrilateral, then values of x is 245 and the value of y is 341

Angle sum property of quadrilateral:

The angle sum property states that the sum of all the angles of the quadrilateral is 360 degree.

Given,

The angles of the quadrilateral are 5x degrees, (4y minus 2 )degrees, (13x plus 10 )degrees, and 10y degrees.

Now we have to write and solve a system of linear equations to find the values of x and y.

While we looking into the given angles, then we get the values

=> 5x°

=> (4y - 2)°

=> (13x + 10)°

=> 10y°

We know that, the sum of all the angles of the quadrilateral is 360°.

So, it ca be written as,

=> 5x° + (4y - 2)° + (13x+ 10)° + 10y° = 360°

=> 18x° + 14y° - 8° = 360°

=> 18x° + 14y° = 354°

When we divide all of them by 2, then we get the equation as,

=> 9x° + 7y° = 177°

Now we have to rewrite the given equation as,

=> 9x° = 177° - 7y°

=> x° = (177° - 7y°)/9

Apply these value on the angles, then we get,

=> 13(177 - 7y)/9 = -10

=> 13(177 - 7y) = 90

=> -7y = -90 - 2301

=> 7y = 2391

=> 341

Then the value of x is

=> 245

A certain insect can beat its wings 10 times per second. Write an equation in slope-intercept form that shows the relationship between flying time in seconds and the number of times the insect beats its wings.

Answers

The equation in slope-intercept form that shows the relationship is y = 10x

How to determine the equation?

From the question, we have the following parameters that can be used in our computation:

Rate of beating wings = 10 times per second

The equation in slope-intercept form of the relationship is then represented as

y = Rate of beating wings * x

Where

y is the number of times

x is the wings

So, we have

y = 10 * x

Evaluate

y = 10x

Hence, the equation is y = 10x

Answers

The unit rate is 32.6 ft/s and approximately 0.03 s/ft.

What is Unitary Method?

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

Given:

An object traveled 691.12 feet in 21.2 seconds.

So, the unit rate as feet per second.

= 691.12/ 21.2

= 32.6 ft/s

and, the unit rate as second per feet

= 21.2/ 691.12

= 0.03 s/ ft

Hence, the unit rate is 32.6 ft/s and approximately 0.03 s/ft

an article in a medical journal suggested that approximately 18% of such operations result in complications. using this estimate, what sample size is needed so that the confidence interval will have a margin of error of 0.06?

Answers

The needed Sample size is 32.2 so that the confidence interval will have a margin of error of 0.06.

We have provided that , An article in a medical journal approx. 18% of operation results complications.

Using the estimate formula, for standard margin of error

Margin of error (E) = Z x √p(1-p)/n

where , E---> margin of error

Z---> estimate value

p----> sample proportion

n -----> Sample size

we have the value of E = 0.06 , p = 18% = 0.18

put all the values in above formula we get,

0.06 = Z × √0.18× 0.82/n

critical value or Z-value for sample proportion 0.18 is 0.91

Now, 0.06 = 0.91 × √0.18×0.82/n

=> √0.14/n= 0.065 => 0.14/n = 0.0043

=> n= 32.2

The reason that proves the above conditions is option A. Definition of supplementary angles And Substitution property.

Supplementary angles:

The pair of angles that gives 180° on adding is known as Supplementary angles. In other words, the sum of two supplementary angles is 180°. Two pairs of Supplementary angles will always form a linear pair.

Here we have

∠1,  ∠2,  ∠3, and ∠4 are formed by 2 intersecting lines

As we know      

∠1,  ∠2 is a linear pair and form supplementary angles

=> Sum of the ∠1,  ∠2 will equal 180°  

∠2,  ∠3 is a linear pair and form supplementary angles

=> Sum of the ∠2,  ∠3 will equal 180°  

Therefore,

By the Definition of supplementary angles ∠1+∠2= 180° and ∠2+∠3= 180°

From the above observations,

=> ∠1+∠2= 180° and ∠2+∠3= 180°

=> ∠1 + ∠2 = ∠2 + ∠3  

Therefore,

By the Substitution property ∠1 + ∠2 = ∠2 + ∠3

Write the equation of the line that goes through point (-4, 1) and is perpendicular to the line 2y - 4x = -10. Write the equation in slope intercept form.​

Answers

Answer:

y = 1/2x + 3

Step-by-step explanation:

first we change the first equation to slope-intercept form to find the reciprocal slope

2y - 4x = -10

add 4x to both sides

2y = 4x - 10

divide both sides by 2

y = 2x - 5

since perpendicular lines have reciprocal slopes the slope of our new line is 1/2

y = 1/2x + b

to find b we plug in the point

1 = 1/2(-4) + b

1 = -2 + b

add 2 to both sides

3 = b

i need to know how to find the slope!!

Answers

Answer:

Step-by-step explanation:

Slope of a straight line is the gradient of that line.

Formula for gradient is rise over run. Meaning: m = (y2 - y1) / (x2 - x1)

To use this formula, you need 2 points of the straight line. They have already given you one: (8, -3). For the second one, we consider the equation of the line. The y-intercept is given too: -4.

Now, keep in mind, the y intercept is the point of the line that passes from x = 0. Meaning, the point where the line touches the y axis, and at y axis, x = 0. So our second point is (0, -4).

Now as we have 2 points, (8, -3) and (0, -4), we put the values in the formula: m = (y2 - y1) / (x2 - x1) = (-4 - (-3)) / (0 - 8) = -1 / -8 = 1 / 8

The value of f(x) in 9 years is $11,750.

What is the value of the cars in 9 years?

The value of the car declines with the passage of time. Thus, the value of the car depreciates with the passage of time.

A linear function is a function that has a single variable raised to the power of 1. A linear function increases or decreases by a constant value.  

The general form of a linear function is f(x) = a + bx

Where:

a = initial value b = rate of change x = number of years

Rate of change = value of the car B in year 2 - value of the car B in year 1

17,000 - 17,750 = - 750

g(x) = 18,500 -750x

Value of g(x) when x is 9:

g(x) = 18,500 -750(9)

g(x) = 18,500 - 6,750

g(x) = $11,750

An exponential function can be described as an equation with exponents. The exponent is usually a variable.

The general form of exponential function is f(x) = [tex]e^{x}[/tex]

Where:

• x = the variable

• e = constant

Constant = (Value of the car in year 2 / value of the car in year 1) - 1

Constant = (16,346.60 / 17,390) - 1 = -0.06 = -6%

g(x) = [tex]18,000(0.94^{x})[/tex]

Answer:

m∠T = 60°

m∠U = 60°

TS = 13 cm

SU = 13 cm

Step-by-step explanation:

The diagram shows that 2 sides, UT and TS, are equal, so it is an isosceles triangle. Since it is an isosceles triangle, the two angles opposite the equal sides are also congruent to each other, so m∠S = m∠U = 60°.

Now we know the measure of 2 angles, we can find the measure of the third angle, by subtracting the 2 known angles from 180°.

m∠T = 180° - m∠S - m∠U

m∠T = 180° - 60° - 60°

m∠T = 60°

Since all 3 angles are congruent, it is an equilateral triangle, therefore all the sides must be congruent too. So UT = TS = SU = 13 cm.

What is Differential equation?

A differential equation is an equation that contains one or more functions with its derivatives.

The marginal cost represents the additional cost if 1 more unit is produced. So, we can find the marginal cost by computing C(1,001) and subtracting (1,000)

First, let's evaluate the cost at both x= 1,001 and x=1,000

C(1000)=0.002(1000)^2+8(1000)+6000

=0.002(1000000)+8000+6000

=2000+8000+6000

=16000

C(1001)=0.002(1001)^2+8(1001)+6000

=2004.002+8008+6000

=16012

The difference between these costs is $12.002. Rounding to the nearest cent, we find a marginal cost of $12 per unit. Let's see if we get a similar result from the derivative.

Hence 12 is the marginal cost at the production level of 1000 units.
