Given

A laboratory technician needs to make a 117-liter batch of a 20% acid solution.

 How much the  technician combine  an acid solution that is pure acid with another that is 10% to get the desired concentration.

To proof

let us assume that the solution that is pure acid = x liters

let us assume that the anthor solution that is 10% = y liters

Than

the  equation becomes

x + y = 117

As given in the question

technician needs to make a 117-liter batch of a 20% acid solution

laboratory technician combine  an acid solution that is pure acid with another that is 10% to get the desired concentration

Convert 20% in the simpler form

[tex]=\frac{20}{100}[/tex]

= 0.2

Convert 10% in the simpler form

[tex]=\frac{10}{100}[/tex]

= 0.1

Than the equation becomes

0.2 × 117 = x + 0.1y

234 = 10x + y

Than the two equation are  

x + y = 117

234 = 10x + y

subtracted x + y = 117 from 234 = 10x + y

10x+y -x -y = 234 -117

9x = 117

x= 13

put this in the equation x + y = 117

13 + y =117

y = 117 - 13

y = 104

Therefore

The solution that is pure acid be 13 liters.

than the other solution that is 10% is 104 liters.

Hence proved

One Solution: Simplify to get 5x+4=5x+4

The equation 4x + x + 4 = 8x - 3x + 4 has infinitely many solutions.

To solve the equation 4x + x + 4 = 8x - 3x + 4, we first simplify both sides

5x + 4 = 5x + 4

Next, we subtract 5x from both sides:

4 = 4

Since the equation simplifies to a true statement (4 = 4), this means that the equation is true for any value of x.

Hence, the equation has infinitely many solutions.

In the equation y = 3/4x -3, 3/4 is the slope and -3 is the y-intercept. To graph this, start at -3 on the y-axis, then for each increase of 1 in the x direction, go up by 3/4 in the y direction, drawing a line through these points.

The equation y = 3/4x - 3 represents a straight line in mathematics. The first step to getting your graph is to understand the equation structure: y = mx + b, in which 'm' is the slope and 'b' is the y-intercept. Hence, in your equation the slope is 3/4 and the y-intercept is -3. When x = 0, y will be -3. This is your starting point on the graph.

To construct the graph of this equation, you'd use the slope (3/4), which means to every 1 unit increase in 'x', 'y' will increase by 3/4 units. Start at your y-intercept (-3), then rise 3 units and run 4 units to the right to plot your next point. Continue this until you have a several points. Once you have enough points, you can draw a line through them to represent the equation y = 3/4x - 3.

To determine the number of rows and the number of each type of plant Stacy can have, we need to find the greatest common factor (GCF) of the plant counts. The GCF represents the number of plants in each row. The GCF of 27, 45, and 54 is 9, so Stacy can have 9 rows with 3 tomato plants, 5 bean plants, and 6 carrot plants in each row.

To determine the greatest number of rows that Stacy can have in her vegetable garden while still using all of her plants, we need to find the greatest common factor (GCF) of the numbers 27, 45, and 54. The GCF will represent the number of plants Stacy can have in each row.

First, we can find the GCF of 27 and 45 by listing their factors:

27: 1, 3, 9, 27

45: 1, 3, 5, 9, 15, 45

The greatest common factor of 27 and 45 is 9.

Next, we find the GCF of 9 and 54:

9: 1, 3, 9

54: 1, 2, 3, 6, 9, 18, 27, 54

The greatest common factor of 9 and 54 is 9.

Therefore, Stacy can have 9 rows in her garden, and each row will have 3 tomato plants, 5 bean plants, and 6 carrot plants.

Subtraction = Minus of any two or more numbers with each other called subtraction.

For example = 4 - 8

Division = divide any two numbers or variable called division.

For example 4/8

Multiplication = to multiply any two or more numbers or variables called multiplication.

For example 5 × 7.

Given that,

Total gas available 65000 gallons round down as 60000

Gas is consumed between New York and Los Angeles = 7460 round-up as 7000

Let the person's arm length be = x

Condition is : sleeve lengths available from 20 inches to 40 inches and the length of the sleeves should be about 1.2 times a person's arm length.

So, the inequality equation becomes:

[tex]20\leq1.2x\leq40[/tex]

This gives x=[tex]\frac{20}{1.2}=16.66[/tex] or [tex]16\frac{2}{3}[/tex]

or x=[tex]\frac{40}{1.2}[/tex]=33.33 or [tex]33\frac{1}{3}[/tex]

Hence, the shop does not provide tuxedos to people with arm length less than 16.66 inches and greater than 33.33 inches.

Answer:

Step-by-step explanation:

Let the arm length of tuxedo be x which varies from 20 inches to 40 inches.

If length of the sleeves is about 1.2 times a person's arm length.

Then the arm length of a person will be 1.2x.

Inequality for the arm length will be

20 < 1.2x < 40

Now we divide this inequality by 1.2

[tex]\frac{20}{1.2}<x<\frac{40}{1.2}[/tex]

16.67 < x < 33.33

This inequality represents the arm length of people having arm length between 16.67 and 33.33 inches.

tuxedo rental shop does not provide tuxedos to the persons having arm length less than 16.67 and greater than 33.33.

The equation that represents this situation is 1.05c + 0.76b = 10.

The equation that represents this situation is option A, which is 1.05c + 0.76b = 10.

To understand why this is the correct equation, let's break it down. The equation represents the total cost of the broccoli and cauliflower Tawny needs to buy. The cost of broccoli is given as $1.05 per pound, so we multiply this cost by the number of pounds of broccoli (b) Tawny wants to buy. Similarly, the cost of cauliflower is given as $0.76 per pound, so we multiply this cost by the number of pounds of cauliflower (c) Tawny wants to buy. The sum of these two costs should be equal to $10, which is Tawny's desired spending amount.

The large bag of pretzels is the better buy as it has a lower cost per ounce at $0.1993 compared to $0.2475 per ounce for the small bag.

To determine which bag of pretzels is the better buy, we need to calculate the cost per ounce for each bag. For the small bag, we divide $0.99 by 4 ounces to get the cost per ounce. For the large bag, we divide $2.99 by 15 ounces to find its cost per ounce. Once we have both costs per ounce, we can compare them to see which bag offers the lower cost per ounce and hence the better value.

For the small bag:

$0.99 / 4 ounces = $0.2475 per ounce

For the large bag:

$2.99 / 15 ounces = $0.1993 per ounce

Comparing the two, we can see that the large bag of pretzels offers a lower cost per ounce and is therefore the better buy.

The division of 32,111 by 181 gives a quotient of 177 and a remainder 104. In essence, when 32,111 is divided by 181 completely, there is left an undivided 104.

In Mathematics, to determine the remainder of a division problem, you perform the division operation as usual and then observe the residual value. That residual value is the remainder. In your case, when 32,111 is divided by 181, the result is 177 with a remainder of 104. Therefore, the answer to your question '32,111 ÷ 181, what is the remainder?' is 104, this is the amount that can't be evenly divided over 181. It is known as the remainder of the division operation.

To round 936,292 to the nearest hundred thousand, you look at the ten thousand place. Since it's 3, which is less than 5, 936,292 rounds down to 900,000.

To round 936,292 to the nearest hundred thousand, we need to look at the ten thousand digit, which is 3. Since this number is less than 5, we do not round up the hundred thousand digit. Therefore, 936,292 rounded to the nearest hundred thousand is 900,000.

Rounding to the nearest hundred thousand means replacing all the digits to the right of the hundred thousand place with zeros. If the digit in the ten thousand place is five or higher, we add one to the hundred thousand digit. If it's lower than five, we keep the hundred thousand digit the same.
