Pure acid is to be added to a 10% acid solution to obtain 90L of 81% solution. What amounts of each should be used?How many liters of 100% pure acid should be used to make the solution? 04

Answers

Answer 1

Let's use the variable x to represent the amount of pure acid and y to represent the amount of 10% acid.

Since the total amount wanted is 90 L, we can write the equation:

[tex]x+y=90[/tex]

Also, the final solution is 81%, so we can write our second equation:

[tex]100\cdot x+10\cdot y=81\cdot(x+y)[/tex]

From the first equation, we can solve for y and we will have y = 90 - x.

Using this value in the second equation, we have:

[tex]100x+10(90-x)=81(x+90-x)[/tex]

Solving for x, we have:

[tex]\begin{gathered} 100x+900-10x=81\cdot90 \\ 90x+900=7290 \\ 90x=7290-900 \\ 90x=6390 \\ x=\frac{6390}{90} \\ x=71 \end{gathered}[/tex]

Therefore the amount of pure acid to be used is 71 L and the amount of 10% acid is 19 L.

Solve the following inequality: 6p - 15 < 33

Answers

WE are to solve an inequality, so we proceed to isolate the variable "p" on one side of the inequality symbol:

6 p - 15 < 33

we add 15 to both sides:

6 p < 33 + 15

6 p < 48

now divide both sides by 6 (notice that since 6 is a positive number, the division doesn't change the direction of the inequality)

p < 48/6

Answers

Leah, this is the solution:

Variables:

Let x to represent the weight of one Hershey kiss

Let y to represent the weight of one Reese cup

System of equations:

6x + 6y = 82.4

4x + 5y = 63.8

______________

Let's multiply the second equation by - 3/2, therefore:

6x + 6y = 82.4

-6x - 15y/2 = -95.7

________________

-15/2 + 6 = -3/2

_________________

-3y/2 = -13.3

Dividing by -3/2 at both sides:

-3y/2 / -3/2 = -13.3 / -3/2

y = 8.87

______________

Replacing y in the first equation and solving for x:

6x + 6 * 8.87 = 82.4

6x + 53.22 = 82.4

Subtracting 53.22 at both sides:

6x +53.22 - 53.22= 82.4 - 53.22

6x = 29.18

Dividing by 6 at both sides:

6x/6 = 29.18/6

x = 4.86

_________________

In conclusion, one Hershey kiss weights 4.86 ounces and one Reese cup weights 8.87 ounces.

Answer:

So, the percentage is equal to:

[tex]\frac{18}{60}\times100\text{ \% = 30\%}[/tex]

Therefore, 30% of the randomly selected students are left-handed.

Now, we can use this percentage to estimate the number of left-handed students in the group of 280.

Then, 30% of 280 is equal to:

[tex]30\text{ \% }\times280=\frac{30}{100}\times280=84[/tex]

The diameter is defined as twice the length of the radius of the circle. The radius is measured from the centre of the circle to one endpoint on the boundary of the circle, while the diameter is the distance  measured from one end of the circle to a point on the other end of the circle that passes through the centre. This is indicated by the letter D. The circumference of  a circle has an infinite number of points, which means that the circle has an infinite number of diameters and each diameter of the circle is the same length.

Answers

The most appropriate choice for equation of line in slope intercept form will be given by-

y = 2x - 8 is the required equation of line

What is equation of line in slope intercept form?

The most general form of equation of line in slope intercept form is given by y = mx + c

Where m is the slope of the line and c is the y intercept of the line.

Slope of a line is the tangent of the angle that the line makes with the positive direction of x axis.

If [tex]\theta[/tex] is the angle that the line makes with the positive direction of x axis, then slope (m) is given by

m = [tex]tan \theta[/tex]

The distance from the origin to the point where the line cuts the x axis is the x intercept of the line

The distance from the origin to the point where the line cuts the y axis is the y intercept of the line

Here,

The given equation of line is y= 2x +3

Slope of this line = 2

Slope of the line parallel to this line = 2

The line passes through (-2, -12)

Equation of the required line = y - (-12) = 2(x - (-2))

                                                = y + 12 = 2x + 4

                                                = y = 2x + 4 - 12

                                                = y = 2x - 8

Let x be the miles driven and y be the earnings of the company when they drive for x miles.

If the company charges $0.17 per mile driven plus a flat rate of $85, then the total cost for moving x miles away is,

[tex]y=85+0.17x[/tex]

Now, we have to find for how many miles, x, the company must drive to earn $100 or more,

[tex]85+0.17x\ge100[/tex]

Subtract 85 from both sides,

[tex]\begin{gathered} 85-85+0.17x\geq100-85 \\ \\ 0.17x\ge15 \end{gathered}[/tex]

Answers

The hours when the prices of the two stocks be the same is 2.38 hours.

How to illustrate the information?

From the information, the price of Stock A at 9 A.M. was $12.42 and the price has been increasing at the rate of $0.12 each hour. This will be the expressed as 12.42 + 0.12h.

At noon the price of Stock B was $12.92. It begins to decrease at the rate of $0.09 each hour. This will be:

= 12.92 - 0.09h

where h = number of hours

Equate both equations. This will be:

12.42 + 0.12h = 12.92 - 0.09h

Collect like terms

12.92 - 12.42 = 0.12h + 0.09h

0.21h = 0.50

h = 0.50 / 0.21

h = 2.38 hours.

1. Abby baked 2-dozen brownies. She took 1 dozen to her scout meeting. Her family ate 8, and she put the rest in a container in the refrigerator. How can Abby find the number of brownies left in the refrigerator?

Answers

In order to determine the amount of brownies left in the refrigerator, subtract 8 from 12.

How many brownies are left in the refrigerator?

If Abby bakes 2 -dozen brownies, she baked 24 brownies. There are 12 pieces in 1 dozen, thus if she bakes two dozens, she baked 24 brownies ( 12 x 2).

The amount of brownies left after she takes one dozen to school = amount baked - amount taken for the meeting

24 - 12 = 12

Amount left in the refrigerator : amount left after she took a dozen for the meeting - amount eaten by her family

12 - 8 = 4

Please help me come you just tell me the answer I don’t really need you to explain

Given:

[tex]\begin{gathered} \angle JKL=65 \\ \angle KJL=50 \end{gathered}[/tex]

Sum of the angle of any triangle is 180

So:

[tex]\begin{gathered} \angle JKL+\angle KJL+\angle KLJ=180 \\ 65+50+\angle KLJ=180 \\ \angle KLJ=180-(65+50) \\ \angle KLJ=180-115 \\ \angle KLJ=65 \end{gathered}[/tex]

Then two sides are also equal.

[tex]\begin{gathered} 3x-2=x+10 \\ 3x-x=10+2 \\ 2x=12 \\ x=\frac{12}{2} \\ x=6 \end{gathered}[/tex]

So the value of x is 6.

Which statements describe one of the transformations performed on f(x) = x?to create g(x) - 3(x + 5)2 - 2? Choose all that apply.DA. A translation of 2 units to the leftI B. A vertical stretch with a scale factor of 3O C. A vertical stretch with a scale factor of3O D. A translation of 5 units to the left

Answers

Solution:

The Function transformation of f(x) is:

[tex]g(x)=f(x+c)+d[/tex]

If c > 0, then the graph shift left f(x+c).

If c<0, then the graph shift right f(x-c)

If d > 0, then the graph shift up f(x) +d

If d < 0, then the graph shift down f(x) -d

When the given equation is:

[tex]f(x)=x^2[/tex]

The transformation equation is given:

[tex]g(x)=3(x+5)^2-2[/tex]

Then, the graph shifts down 2 units and shifts left 5 units.

Also, the vertical stretch with a scale factor 3.

Therefore, the correct options are B and D.
