He would have to $3.17 in taxes

Step-by-step explanation:

Answer:

l = 32.57, w = 24.43, h = 8.14

Step-by-step explanation:

volume = l*w*h

l = 4x

w = 3x

h = x

540 = 4x * 3x * x

540 = 12x^3

[tex]\sqrt[3]{540}[/tex] = 8.14

l = 4x = 4(8.14) = 32.57

w = 3x = 3(8.14) = 24.43

h = x = 8.14

Answer:

61

Step-by-step explanation:

The sum of the three angles of any triangle is equal to 180 degrees.

180-58=122

122/2=61

We divide by two because we are missing the other two angles but they are both equal.

Answer:

[tex]\frac{5}{3}[/tex] or [tex]1\frac{2}{3}[/tex] cups of milk

Step-by-step explanation:

So if you have the ratio of 6 cups of flour to 2 cups of milk you can make this the fraction: [tex]\frac{6}{2}[/tex] and then for the 5 cups of flour to 'x' cups of milk the fraction would be: [tex]\frac{5}{x}[/tex]

To solve for 'x', let the 2 fractions equal each other and cross multiply.

[tex]\frac{6}{2} = \frac{5}{x}[/tex]

[tex]x = \frac{2*5}{6} = \frac{10}{6} = \frac{5}{3} = 1\frac{2}{3}[/tex]

So you would need [tex]\frac{5}{3}[/tex] or 1 and [tex]\frac{2}{3}[/tex] cups of milk for 5 cups of flour.

The time it will take them to finish the journey is 2.6 hours

Speed is defined as the rate of change of position of an object in any direction. Speed is measured as the ratio of distance to the time in which the distance was covered.

It is measured in meter/sec(SI unit). it can also be measured in other units.

Speed is expressed as;

speed = distance /time

distance = 37.7 miles

speed = 14.5 miles per hour

time = distance /speed

= 37.7/14.5

= 2.6 hours.

Therefore it will take them 2.6 hours to finish the journey.

Answer:

[tex]y=55\\x=108[/tex]

Step-by-step explanation:

We know that the total angle sum of the quadrilateral internal angles is 360° since we are working with a quadrilateral polygon.

So when finding the interior angles we set up the equation  of

[tex]125+y=180\\72+x=180[/tex]

Subtract 180 by 125 and 72 to find y and x

[tex]y=55\\x=108[/tex]

Step-by-step explanation:

List price = $65.00

Discount = 35% .

Hence the new price is (100-35)% = 65% of original price .

=> price = $ 65 * 65/100

=> price = $42.25

Answer:

[tex]m = - \frac{1}{4} [/tex]

[tex]c = 2 \frac{3}{4} [/tex]

Step-by-step explanation:

Let's start by finding the point of intersection of the lines x -2y= -1 and y= 2.

x -2y= -1 -----(1)

y= 2 -----(2)

Substitute (2) into (1):

x -2(2)= -1

x -4= -1

x= 4 -1

x= 3

Thus, the point of intersection is (3, 2).

y= 4x +8

Slope= 4

The product of the slopes of perpendicular lines is -1.

4m= -1

m= -¼

y= -¼x +c

Since the line passes through (3, 2), we can substitute this coordinates into the equation to find the value of c.

When x= 3, y= 2,

[tex]2 = - \frac{1}{4} (3) + c[/tex]

[tex]c = 2 + \frac{3}{4} [/tex]

[tex]c = 2 \frac{3}{4} [/tex]

Answer:

(y^2+1)(x^2+1)=k

Step-by-step explanation:

It looks like it is possibly separatable.

Let's try.

Factor the x out on first term and factor the y out on second term:

x(y^2+1)dx+y(x^2+1)dy=0

Subtracting y(x^2+1)dy on both sides:

x(y^2+1)dx=-y(x^2+1)dy

Divide both sides by (y^2+1)(x^2+1):

x/(x^+2+1)dx=-y/(y^2+1)dy

Integrate both sides..

Use substitution u=x^2+1 and v=y^2+1...so du= 2x dx and dv=2y dy.

.5du/u=-.5dv/v

.5ln|u|=-.5ln|v|+c

Multiply both sides by 2:

ln|u|=-ln|v|+c

Plug in our substitutions :

ln|x^2+1|=-ln|y^2+1|+c

Absolute values unnecessary since insides are positive always.... also -ln(y^2+1)=ln(1/(y^2+1))

e^ on both sides:

x^2+1=k(1/y^2+1)

(y^2+1)(x^2+1)=k

Answer:

x>-12

Step-by-step explanation: you have the equation -2x+12 <36

so what do you do first?

you would subtract 36 on both sides like this: -2x+12-36 <-36

then you get -2x < 24

divide both sides by -2  like this : -2/-2x<24/-2

and since your dividing by -2 on both sides

the sign would be less then sign instend of a greater then

so the answer is x>-12

Answer:

see explanation

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 )

(a)

y = - 2x + 5 ← is in slope- intercept form

with slope m = - 2

Parallel lines have equal slopes , then

y = - 2x + c ← is the partial equation

To find c substitute (- 3, 2 ) into the partial equation

2 = 6 + c ⇒ c = 2 - 6 = - 4

y = - 2x - 4 ← equation of parallel line

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

(b)

y = 3x + 4 ← is in slope- intercept form

with slope m = 3

Given a line with slope m then the slope of a line perpendicular to it is

[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{3}[/tex] , then

y = - [tex]\frac{1}{3}[/tex] x + c ← is the partial equation

To find c substitute (3, 2 ) into the partial equation

2 = - 1 + c ⇒ c = 2 + 1 = 3

y = - [tex]\frac{1}{3}[/tex] x + 3 ← equation of perpendicular line
