How many liters each of a 20 % acid solution and a 30 % acid solution must be used to produce 90 liters of a 25 % acid solution? (Roundto two decimal places if necessary.)

Answers

Let x = volume of 20% solution=0.2

Let y = volume of 30% solution=0.3

Equation of total volume:

x + y = 90

Equation of amount of acid:

[tex]\begin{gathered} 0.2x+0.3y=0.25(90) \\ 0.2x+0.3y=22.5 \\ Solve\text{ x+y = 90 , for x} \\ x=90-y \end{gathered}[/tex]

Substitute into the second equation

[tex]\begin{gathered} 0.2(90-y)+0.3y=22.5 \\ 18-0.2y+0.3y=22.5 \\ 0.1y=22.5-18 \\ 0.1y=4.5 \\ \text{divide both side by 0.1} \\ \frac{0.1y}{0.1}=\frac{4.5}{0.1} \\ y=45 \\ \sin ce\text{ x=90-y} \\ x=90-45 \\ x=45 \end{gathered}[/tex]

Therefore 45 liters of 20% solution and 45 liters of 30% solution

Hence the volume of 20% acid = 45 litres

the volume of 30% acid = 45 litres

Answers

The refrigerator is to be set at 5 degrees celsius for the cheese to keep for 5 days.

Since we are given the relation for the exponential function

H(T) = 130 (1/2) ^(T/43.3), where H(T) is the  number of hours

since we are asked for a cheese to keep for  5 days, so

H(T)=  5 * 24 = 120 hours

so the equation we will have

=>120 =130 (1/2) ^(T/43.3)

we multiply both sides by 120

=> 12/13=  (1/2) ^(T/43.3)

taking logarithms on both sides, we get

=> ln (12/13) = (T/43.3) ln(1/2)

=>43.3 ln (12/13) = T ln (1/2)

dividing both sides by ln (1/2), we get

=> T = 43.3  ln (12/13) / ln (1/2)

=> T=  5.0016

=> T = 5.0 celsius

Point (-3,2) Line x + y = 3 (Question parts in the photo, sorry)

Answers

a)

The slope intercept equation of a line is expressed as

y = mx + c

where

m is the slope

c is the y intercept

The given equation is

x + y = 3

y = - x + 3

By comparing both equations,

m = - 1

If two equations are parallel, it means that they have the same slope. Thus, the slope of the parallel line passing through the point (- 3, 2) is - 1

We would find the y intercept by substituting x = - 3, y = 2 and m = - 1 into the slope intercept equation. It becomes

2 = - 1 * - 3 + c

2 = 3 + c

c = 2 - 3

c = - 1

By substituting m = - 1 and c = - 1 into the slope intercept equation, the equation of the line is

y = - x - 1

b) If two equations are perpendicular, it means that the slope of one line is the negative reciprocal of the slope of the other line Thus, the slope of the perpendicular line passing through the point (- 3, 2) is - - 1/1 = 1

We would find the y intercept by substituting x = - 3, y = 2 and m = 1 into the slope intercept equation. It becomes

2 = 1 * - 3 + c

2 = - 3 + c

c = 2 + 5

c = 5

By substituting m = 1 and c = 5 into the slope intercept equation, the equation of the line is

y = x + 5

a) y = - x - 1

b) y = x + 5

Answers

So she has excess of ice cream so we need not worry about that
Now she has 2250ml juice and 2750ml ale
Given that juice and ale are needed in the ratio 4 to 5
So here we find according to the bigger value.
5x=2750 => x= 550ml

The value of y varies directly with x. When y = 21, x = 3. What is the value of y when x is 14

Answers

Answer:

43

Step-by-step explanation:

The value of y varies directly with x. When y = 21, x = 3. What is the value of y when x is 14.

when y = 21 and x = 3 the ratio of y to x is 21 to 3 or (reduced) 3 y to 1 x

This means y is three times the size of x.

When x = 14 then y = 14 × 3 = 42

write a paragraph reflecting on the different methods (graphing technology, tables of values, and successive approximation) of solving f(x) =g(x). state which of the three methods you prefer, and explain why.

Answers

The three methods that are generally used to solve f(x) =g(x) are Graphing technology, Tables of values, and Successive approximation.

Determine the exact value of x by replacing the values of x with f(x) and g(x).

The hit-and-trial technique is used in f(x) = g(x) to compute the exact value of x by selecting an interval and then substituting the value of x in that interval.

This is a bit longer and takes more time.

Graph Technique: Create a graph that contains both f(x) and g(x). The values of x given by these two functions are the same.  Some features are difficult to plot, but once plotting is done, the right solution is obtained. The graphics technique is prioritised in determining f(x) = g(x) and x.

I need help with finding the area and the perimeter for a trapezoid thank you

Answers

From the figure given in the question, we are asked to find the area and perimeter.

(a) Area:

Since the figure is a trapezoid, the formula for the area of a trapezoid is:

Area = (a + b)h

2

Where:

a = 2

b = 5

h = 4

Area = (2 + 5)4

2

Area = 7/2 * 4

Area = 3.5 * 4

Area = 14 cm²

(b) Perimeter:

To get the perimeter, we will have to add all the side length.

But we will have to find the missin side length first.

Using pythagoras:

a² + b² = c²

Where:

a = 4

b = 3

c² = 4² + 3²

c² = 16 + 9

c² = 25

Taking square of both sides:

c = √25

c = 5

Since we have gotten the missing side length as 5cm, we can now add all the given side length to get the perimeter.

Perimeter = 4 + 2 + 5 + 5

Perimeter = 16 cm

x = y + 4

y = x - 4

    Our slope, when the line is written as y = mx + b, is the m value. Our m value here is one, so the slope of a line parallel to the line whose equation is x - y = 4 is 1.
