Answer:

520

Step-by-step explanation:

Let the Ratio a:b:c be 7x:13x:20x Respectively.

So, Sum of Ratios is 520...

A+B+C = 520

7x+13x+20x=520

40x=520

x= 520/40

x= 13

Now, Put the value of x

A= 7x= 7×13= 91

B= 13x = 13×13= 169

C= 20x = 20×13= 260

Now Add the numbers if we get 520 it means all the three numbers are correct....

91+169+260= 520

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 in the picture.

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

Answer:

a, x < y or z < y

b, y > z or y > x

c, x = z

Answer:

$42.25

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:

Step-by-step explanation:

It is often convenient to use a chart to record the logic of the problem. The attached shows a typical arrangement for logic problems of this kind. It lets each category relate to every other category.

We use an X to identify a combination that is ruled out by something in the problem statement. The numbers are used here to identify the statement that gives rise to the chart fill-in. (Note that statement 6 is redundant and is not necessary to solve the problem.)

A Dark green background color is used to identify a primary conclusion. (The first ones are that Ling is from NJ, and Anna is from CA, hence in the math club.) The faded green identifies a secondary conclusion that results after the primary conclusions are reached. (The green square with 5 is faded only to enhance its contrast. It is a primary conclusion based on statement 5.)

Once 2 of 3 squares are filled on a line or column of a 3×3 space, the remaining conclusion is obvious.

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]

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.

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

If Jess wants to make 128 cups of punch then 32 cups of Citrus soda used.

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.

We have,

For 1 cup punch

0.4 cups of orange juice,

0.35 cups of pineapple juice, and

0.25 cups of citrus soda.

So, to make 128 cups the amount of each ingredient used

Orange juice: 128 x 0.4= 51.2

Pineapple juice: 128 x 0.35 = 44.8

Citrus soda: 128 x 0.25 = 32

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
