Answer:

The number of liters of the 45% acid solution = 10 liters

The number of liters of the 70% acid solution is = 40 liters

Step-by-step explanation:

How many liters each of a 45% acid solution and a 70% acid solution must be used to produce 50 liters of a 65% acid solution? (Round to two decimal places if necessary.)

Let x be the number of liters of the 45% acid solution

The number of liters of the 70% acid solution is y

x + y = 50

x = 50 - y

Also

How many liters each of a 45% acid solution and a 70% acid solution must be used to produce 50 liters of a 65% acid solution?

We have:

45% × x + 70% × y = 65% × 50

0.45x + 0.70y = 0.65 × 50

0.45x + 0.70y = 32.5

We substitute x = 50 - y in the equation

0.45(50 - y) + 0.70y = 32.5

= 22.5 - 0.45y + 0.70y = 32.5

= - 0.45y + 0.70y = 32.5 - 22.5

= 0.25y = 10

Divide both sides by 0.25

= y = 10/0.25

y = 40 liters

x = 50 - y

x = 50 - 40

x = 10 liters

Hence,

The number of liters of the 45% acid solution = 10 liters

The number of liters of the 70% acid solution is = 40 liters

Step-by-step explanation:

Answer:

k = $0.50

Step-by-step explanation:

The data that we have is:

Rocko paid: $12.50 for 25 tickets.

Louisa paid: $17.50 for 35 tickets.

Now, the question asks to find the constant of proportionality.

A proportional relation can be written as:

y = k*x

where k is the constant, and in this case, y is the price and x the number of tickets bought.

Then replacing with the values above, we have:

$12.50 = k*25

then:

k = $12.50/25 = $0.50

And the other data:

$17.50 = k*35

K = $17.50/35 = $0.50

So we have the same k in both cases, this means that the constant of proportionality is k = $0.50

i'm not all too familiar with the constant of proportionality, but both of the situations have a ratio of 0.5/1..

12.50/25 = 0.5/1

17.50/35 = 0.5/1

hopefully this can help you in some way! sorry if it doesn't

Answer:

2x + 5y = 36 in standard form

Step-by-step explanation:

m = [tex]\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]

y - [tex]y_{1}[/tex] = m( x - [tex]x_{1}[/tex] )

~~~~~

(3, 6)

(8, 4)

m = [tex]-\frac{2}{5}[/tex]

y - 6 = [tex]-\frac{2}{5}[/tex] ( x - 3 )

y = [tex]-\frac{2}{5}[/tex] x + [tex]\frac{36}{5}[/tex] in slope-intercept form

2x + 5y = 36 in standard form

Answer:

The value of x is $4000.

Step-by-step explanation:

Let's call x to the original price per night of a room in the Dubai hotel.

The price first decreased by 5%. Calculate 5% of x:

5 * x / 100 = 0.05x

Now subtract it from the original price:

x - 0.05x = 0.95x

This new price is then increases 15%. Calculate 15% of 0.95x:

15 * 0.95x / 100 = 0.1425x

Add it to the previous price:

0.95x + 0.1425x = 1.0925x

This price is equal to $4370, thus:

1.0925x = 4370

x = 4370 / 1.0925

x = 4000

The value of x is $4000.

Answer:

1.28 m

Step-by-step explanation:

48/30 = x/.8

cross multiply

30x = 48(.8)

30x = 38.4

x = 38.4/30

x = 1.28 m

Answer:

There are sixteen 15-cent stamps and eight 20-cent stamps.

Step-by-step explanation:

Stamp collector has:

15c stamps

20c stamps

Total value is $4

x($0.15) + y($0.20) = $4.00

The # of 15c stamps is 8 - than 3 * the # of 20c stamps; 15c = 8 - 3c

x = 3y - 8

(3y-8)(0.15)+y(0.20) = $4.00

0.45)y-1.20+(0.20)y = 4.00

(0.65)y-1.20 = 4.00

(0.65)y = 5.20

y = 8

x = 3(8)-8 = 16

There are sixteen 15-cent stamps and eight 20-cent stamps.

Check:

16($0.15)+8($0.20) = $2.40+$1.60 = $4.00

Answer:

B

Step-by-step explanation:

Answer:

The correct option is;

A vertical line can be represented using a table but not a function because the slope is undefined

Step-by-step explanation:

A function, f(x), representing a linear relationship can be presented as follows;

f(x) = m·x + c

Where;

m = The slope = Δy/Δx = (y₂ - y₁)/(x₂ - x₁)

c = The y-intercept

Whereby the line is a vertical line, x₂ = x₁ and x₂ - x₁ =

Therefore;

The slope of a vertical function, m =  (y₂ - y₁)/(x₂ - x₁) = (y₂ - y₁)/0 = ∞ from which we have;

f(x) = ∞·x + c = ∞ which is undefined and the vertical line can only be represented using a table but not a function because the slope is undefined

Answer:

Step-by-step explanation:

1. The available wall space is the difference between the length of the wall and the length of the window:

  9.75 ft - 5.75 ft = 4.00 feet

__

2. At 12 inches per foot, this is ...

  (4 ft)(12 in/ft) = 48 in

__

3. If the pictures are 6 inches wide, Mr. Smith can use ...

  (48 in)/(6 in/picture) = 8 pictures

__

4. If the pictures are 10 inches wide, Mr. Smith can use ...

  (48 in)/(10 in/picture) = 4.8 pictures

There is room for 4 pictures. Space for a fraction of a picture is not useful. This number is even, so 4/2 = 2 pictures can be placed on either side of the window.

Answer:

7 1/2

Step-by-step explanation:

Explanation:

Let's assume these are the different prices of one (1) gallon of paint for three different brand name and choice of colors:

1. Delux brand: Red = $19 per gallon

2. Golden sun: White = $15 per gallon

3. Luxury: Green = $20 per gallon.

Based on the data above, Mang Jose's budget could be drafted:

1. if he chooses the Delux brand/color red, then he will need approximately 11 gallons of the paint (2700/250 square fit) = 10.8, which would cost = $209 (11*$19).

2. if he chooses the Golden sun brand/color white then he will need approximately 11 gallons of paint  (2700/250 square fit) = 10.8, which would cost = $165 (11*$15).

3. if he chooses the Luxury brand/color green then he will need approximately 11 gallons of paint  (2700/250 square fit) = 10.8, which would cost = $220 (11*$20).
