Which quantity is proportional to 35⁄80? Check all that are true. 3⁄5 14⁄36 26⁄52 21⁄48 7⁄16

To divide mixed numbers like 3 1/2 and 2 1/4, first convert to improper fractions. In this case, 3 1/2 divided by 2 1/4 simplifies to 1 5/9.

To solve the problem of 3 1/2 divided by 2 1/4, you need to first convert each mixed number into an improper fraction.

3 1/2 becomes 7/2 and 2 1/4 becomes 9/4, because 3*2 + 1 = 7 (for the first number) and 2*4 + 1 = 9 (for the second number), the numerators of the fractions.

Next, in our division problem, we flip the second fraction (this is the reciprocal), and multiply it with the first. It's the same as multiplying by its inverse to divide fractions.

So, 7/2 divided by 9/4 becomes 7/2*
4/9 which equals 28/18, which can be simplified to 1 10/18 or further simplified to 1 5/9 in mixed number form.

Answer: 5-6i

The rule is that if f(x) has real number coefficients, then a root of x = a+bi pairs up with its conjugate pair of x = a - bi. In this case, a = 5 and b = 6.

Answer:

5 -6i is also the root of  f(x).

Step-by-step explanation:

Given : If 5 + 6i is a root of the polynomial function f(x),

To find  : which of the following must also be a root of f(x).

Solution : We have given that 5+6i is the on of the root of polynomial function f(x).

It has two parts real and imaginary  part so , it is a complex number .

Real part  = 5  and 6i is imaginary part.

Complex conjugate of a complex number is the number with an equal real part and an imaginary part equal in magnitude but opposite in sign. For example, the complex conjugate of a + bi is a − bi.

a = 5 , b = 6.

Then by the complex conjugate defination , Another root would be 5 - 6i

Therefore, 5 -6i is also the root of  f(x).

Answer:

1 3/5 miles per hour

Step-by-step explanation:

Distance = rate * time

We know the distance and the time

2/5 miles = rate * 1/4 hour

Divide by 1/4

2/5   ÷ 1/4 = rate * 1/4 ÷ 1/4

Copy dot flip

2/5 * 4/1 = rate

8/5 = rate

1  3/5 miles per hour is the rate

The numbers that make the statement true are:

( -14, -∞ ) or [-15, -∞).

i.e -15, -16, -17, - 18, -19, ,,,,,,,,,-∞

We need to find all numbers that make this statement true.

More than - addition.

Twice - multiplication of 2.

Less than - <

-∞.......-5 < -4 < -3 < -2 < -1 < 0 < 1 < 2 < < 3 ...........∞

Find the expression.

Let the number be M.

"Nine more than twice a number is less than negative nineteen".

We can write this statement as:

2M + 9 < -19

Find the number M.

2M + 9 < -19

2M < -19 - 9

2M < -28

M < -28/2

M < -14

Let us check the statement is true with M < -14.

2M + 9 < -19

2 x -15 + 9 = -19

-30 + 9 = -19

-21 < -19

This is true.

We see that all numbers below -14 will make the statement true.

So,

The numbers are -15, -16, -17, -18,..........-∞

Thus the numbers that make the statement true are ( -14, -∞ ) or [-15, -∞).

To solve the inequality, we need to translate the given statement into an algebraic expression and then solve for 'x' using subtraction and division.

To solve the inequality, we will translate the given statement into an algebraic expression. Let's say the number is represented by 'x'. 'Twice a number' can be written as 2x. 'Nine more than twice a number' can be written as 2x + 9.

So, the inequality becomes 2x + 9 < -19.

To solve for 'x', we subtract 9 from both sides of the inequality, giving us 2x < -28. Then, we divide both sides by 2, resulting in x < -14.

Therefore, any number less than -14 will make the statement true.

Answer:

x = 2

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y-intercept )

here m = - [tex]\frac{7}{2}[/tex] and c = 12

y = - [tex]\frac{7}{2}[/tex] x + 12 ← equation in slope-intercept form

given (x, 5) lies on the line, solve for x by letting y = 5

- [tex]\frac{7}{2}[/tex] x +12 = 5

multiply all terms  by 2 to eliminate the fraction

- 7x + 24 = 10 ( subtract 24 from both sides )

- 7x = - 14 ( divide both sides by - 7 )

x = 2

Answer:

a(4) = 5 5/6

a(10) = 6 5/6

Step-by-step explanation:

To find the 4th term, let n =4

a(n) = 5 + (n + 1) 1/6

a(4) = 5 + (4+1) 1/6

        =5+5 * 1/6

         = 5 + 5/6

          = 5 5/6

To find the 10th term, let n =10

a(n) = 5 + (n + 1) 1/6

a(10) = 5 + (10+1) 1/6

        =5+11 * 1/6

         = 5 + 11/6

          = 5 + 1 5/6

         = 6 5/6

To find the percent of change from 500,000 to 10,000, subtract 10,000 from 500,000 to get 490,000, then divide that difference by the original number and multiply by 100 to get the percentage.

To find the percent of change from 500,000 to 10,000, we need to calculate the difference between the two numbers and then find the percentage of that difference relative to the original number.

Step 1: Find the difference: 500,000 - 10,000 = 490,000.

Step 2: Find the percent: (490,000/500,000) × 100 = 98%.

The percent of change from 500,000 to 10,000 is 98%.

Answer:

The 3rd equation on the left column  and second one on the right column.

Step-by-step explanation:

These 2 equations have same  coefficients of x and y if we divide the first one by 4 and the second by 2.

This gives the 2 equations

x^2 + y^2 - 4x + 6y - 7 = 0

x^2 + y^2 - 4x + 6y - 20 = 0

If we compete the square on these we get

(x - 2)^2 + (y + 3)^2 =  20

(x - 2(^2 + (y + 3)^2 =  33

These are in standard form . The center is the same (2, -3) but the radii are different so they are concentric.

In mathematics, concentric circles have the same center but different radii. Their general equation is (x-h)²+ (y-k)² = r², sharing the same (h, k) coordinates. Examples include equations like (x - 2)² + (y - 3)² = 4 and (x - 2)² + (y - 3)² = 9.

In mathematics, concentric circles are circles that share the same center but have different radii. The general equation of a circle is given by (x - h)² + (y - k)² = r², where (h, k) is the center and r is the radius. Two such equations will represent concentric circles if and only if their center coordinates (h, k) are the same.

For example, consider the equations:

(x - 2)² + (y - 3)² = 4

(x - 2)² + (y - 3)² = 9

Both these circles have the center at (2, 3) but different radii (2 and 3 respectively), making them concentric circles.

Answer:

(4,1)

Step-by-step explanation:

3x+4y=16

-4x-3y=-19

I will solve this system by elimination.  I will eliminate x

Multiply the first equation by 4 and the second equation by 3

4 (3x+4y)=4*16

12x + 16y = 64

3 (-4x-3y)=3*-19

-12x -9y = -57

Add the two modified equations together to eliminate x

12x + 16y = 64

-12x -9y = -57

-----------------------

7y = 7

y=1

We still need to find x

3x+4y = 16

Substitute y=1

3x+4(1) = 16

3x+4=16

Subtract 4 from each side

3x = 16-4

3x =12

Divide each side by 3

3x/3 = 12/3

x=4

Answer:  The required solution is (x, y) = (4, 1).

Step-by-step explanation:  We are given to solve the following system of linear equations :

[tex]3x+4y=16~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)\\\\-4x-3y=-19~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(ii)[/tex]

We will be using the method of Elimination to solve the given system as follows :

Multiplying equation (i) by 4 and equation (ii) by 3, we have

[tex]4(3x+4y)=4\times16\\\\\Rightarrow 12x+16y=64~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(iii)[/tex]

and

[tex]3(-4x-3y)=-19\times3\\\\\Rightarrow -12x-9y=-57~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(iv)[/tex]

Adding equations (iii) and (iv), we get

[tex](12x+16y)+(-12x-9y)=64+(-57)\\\\\Rightarrow 7y=7\\\\\Rightarrow y=\dfrac{7}{7}\\\\\Rightarrow y=1.[/tex]

Substituting the value of y in equation (i), we get

[tex]3x+4\times1=16\\\\\Rightarrow 3x+4=16\\\\\Rightarrow 3x=16-4\\\\\Rightarrow 3x=12\\\\\Rightarrow x=\dfrac{12}{3}\\\\\Rightarrow x=4.[/tex]

Thus, the required solution is (x, y) = (4, 1).

Answer: whats the question

Step-by-step explanation:

The height of the first copy is 20 cm, and the height of the second copy is 17 cm, after applying the percentages to each successive copy.

The subject of your question falls into the category of Mathematics, particularly in the domain of ratios and percentages. In order to answer your question, we must make a sequence of percentage calculations based on the original height of the photo.

Firstly, if the height of the first copy is 80% of the original photo's height, then the calculation should look like this: 0.80 * 25 cm = 20 cm. Therefore, the first copy's height is 20 cm.

Secondly, the height of the next copy is said to be 85% of the FIRST copy's height. Therefore, we proceed with a similar calculation: 0.85 * 20 cm = 17 cm. This implies that the height of the second copy is 17cm.

Answer: Choice A -- f(x) = (1/3)*|x|

============================================

The input of a function is x and the output is y = f(x)

To vertically compress a function, we will multiply the y value by some fraction smaller than 1. This is so that the y coordinates are a fraction of what they once were.

In this case, we multiply y by 1/3 so that something that has a y coordinate of y = 81 becomes y = 27 (divide by 3)

So we have y = f(x) become (1/3)*y = (1/3)*f(x) = (1/3)*|x|

Step-by-step explanation:

Please, see the attached file.

Thanks.

Answer:

Hence final answer is x=34

Step-by-step explanation:

∠ADC= ∠EDF {Vertically opposite angles are always equal}

∠ADC= 36°  {Given }

∠ADB= 36°...(i)  {Same angles}

∠ABI + ∠ABC = 180° {supplementry angles }

113° + ∠ABC = 180°  {Given }

∠ABC = 180° - 113°

∠ABC = 67°

∠ABD = 67° ...(ii)  {same angle}

We know that sum of all three angles of triangle is 180 degree so we can write:

∠ABD + ∠ADB + ∠BAD =  180°

67° + 36° + ∠BAD =  180°  {using (i) and (ii) }

67° + 36° + x°+43° =  180°  {from diagram }

146° + x° =  180°

x° =  180° - 146°

x° =  34°

Hence final answer is x=34
