Answer:

A) solution 2 is more acidic than solution 1

Step-by-step explanation:

A chemist prepares two acid solutions:

Solution 1: 3 parts sulfuric acid to 7 parts water

Ratio of sulphur to water: 3/7 (3:7)

Solution 2: 4 parts sulfuric acid to 9 parts water

Ratio of sulphur to water: 4/9 (4:9)

___________________________________________________

Part A: (using ratios to determine which solution is more acidic)

First we make same denominator, since the denominators are 9 and 7, we have to find the lcm (lowest common multiple) they both have with is 63. To do that, we must multiply the denominators with either 7 or 9.

Solution 1: Numerator (3) multiplied by 9 and then denominator (7) multiplied by 9. This makes out fraction/ratio 27/63

Solution 2: Numerator (4) multiplied by 7 and then denominator (9) multiplied by 7. This makes out fraction/ratio 28/63

Since 28/63 (or just 28) is a larger quantity than 27/63 (or just 27) this means solution 2 is more acidic than solution 1.

Mathematical Line (Not sure what you would call this lol): 28 > 27

Part B: (Let 'y' amount of sulfuric acid mix with 'x' amount of water)

Equation of solution 1: y = 3/7x

Equation of solution 2: y = 4/9x

Please find attachment for graph.

Part C: Don't have a graph, sorry! (part a. method is more preferred to find more acidic because it gives the actual acidic amount.)

Answer:

Step-by-step explanation:

You want the equations for the inequalities shown on the graph.

The downward sloping dashed line crosses the y-axis at y=3. It has a "rise" of -2 units for each 1 unit to the right. Its slope is rise/run = -2/1 = -2.

The equation for this boundary line can be written ...

  y = -2x +3

The graph is shaded above this line, which is not included in the solution. The inequality graphed is ...

  y > -2x +3

The upward sloping solid line crosses the y-axis at y=0 and has a rise of 1 for each run of 1 unit to the right. Its slope is 1/1 = 1, and its y-intercept is 0.

The equation for the boundary line can be written ...

  y = 1x +0

The graph is shaded below the solid boundary line, so the boundary is included in the solution. The inequality graphed is ...

  y ≤ x

Step-by-step explanation:

As per the given data, Alicia can accommodate 17 more people without reserving another bus.

A field trip is a type of educational excursion that is usually organized by schools, colleges, or other educational institutions.

Alicia has already reserved 3 buses since 3 x 36 = 108 people can fit on those buses.

There are 127 - 108 = 19 people who have not been accounted for on those buses.

Since each bus holds 36 people and there are 19 people who still need to be accounted for, Alicia can still add 36 - 19 = 17 more people before she needs to reserve another bus.

Therefore, Alicia can still sign up 17 more people before needing to reserve another bus.

Important info:

- Sophia has $6 to spend on lunch

- Concession stands sell sodas for $0.75

- All of their food items for $1.50

- Pretend she buys one drink

- Find the maximum amount of food she can buy now.

Process:

Subtract 600 and 75 since $6 = 600 cents

600 - 75 = 525

So Sophia has $5 and 25 cents left

Each food item is worth $1.50 which is 150 cents and she currently has $5.25 which is 525 cents

So divided 525 and 150

525 / 150 = 3.5

Unfortunately she can't buy half of a food item so the answer would be 3

Final Answer:

3, Sophia can buy 3 food items after buying 1 drink

Answer:

To find the greatest number of stickers Cassie can place on a page that is 11 inches long and 8 inches wide without them overlapping, we need to use the same approach as before.

Firstly, we need to calculate the maximum number of stickers that can fit along the length of the page, which is now 11 inches. Since each sticker is 3 inches long, we can fit 3 stickers along the length (11 ÷ 3 = 3 with a remainder of 2).

Next, we can calculate the maximum number of stickers that can fit along the width of the page, which is still 8 inches. Since each sticker is 2 inches wide, we can fit 4 stickers along the width (8 ÷ 2 = 4).

To ensure that the stickers do not overlap, we can only use the full row of 3 stickers from the previous calculation. Therefore, we can place 3 stickers along the length and 4 stickers along the width, giving us a maximum of 12 stickers that Cassie can place on the page without them overlapping.

Answer:

16

Step-by-step explanation:

First, find out how much stickers you can put on the long side:

Lastly, calculate them together:

4x4=16

Answer:

volume = length×width×height

Step-by-step explanation:

box 1

12×2×7 = 24×7 =168

box 2

9×2×5 = 10×9 = 90

total vloume = 168+90 = 258cubic inches.

Answer:

258 cubic inches

Step-by-step explanation:

Shape one has dimensions of: height 12in, width 7in, and depth 2in

Multiply those together you get the volume or 168 cubic inches.

Then you have to multiply the dimensions of the second shape which are : height 5in, width 9in, and depth 2in to get a volume of 90 cubic inches for the second shape.

Then you add the two volumes together to find the total volume

168 cubic inches + 90 cubic inches = 258 cubic inches

Let's consider an exponential decay function.

As an example, let's look at \(f(\text{x}) = 100(0.5)^{\text{x}}\)

Here is a table of selected values:

\(\begin{array}{|c|c|} \cline{1-2}\text{x} & \text{f(x)}\\\cline{1-2}0 & 100\\\cline{1-2}1 & 50\\\cline{1-2}2 & 25\\\cline{1-2}3 & 12.5\\\cline{1-2}4 & 6.25\\\cline{1-2}5 & 3.125\\\cline{1-2}6 & 1.5625\\\cline{1-2}\end{array}\)

As x gets bigger, y = f(x) is slowly approaching y = 0. It will never get to this exact value because we keep taking half of the previous y value (eg: we go from y = 25 to y = 12.5); there's no way to arrive at zero through this continuous halving process. If x/2 = 0, then x itself must be 0. But we started off with a nonzero value.

Visually, the curve is slowly approaching the x-axis. We say that the horizontal asymptote is y = 0 which is directly overlapping the x-axis. Think of the asymptote as an electric fence you can get closer to but not actually touch.

See the graph below. I used Desmos to create the graph.

Option (C) 484 ft²

The Five Sided figure can be divided into 2 Triangles and 1 Rectangle.

Length of the triangle = 22 Feet

Breadth of the triangle = 8 Feet

Area of the triangle = (Length * Breadth) / 2

                                 = (22 * 8) / 2

                                 = 176/2

                                 = 88 ft²

Length of the triangle = 22 Feet

Breadth of the triangle = 4 Feet

Area of the triangle = (Length * Breadth) / 2

                                 = (22 * 4) / 2

                                 = 88/2

                                 = 44 ft²

Length of the rectangle = 22 Feet

Breadth of the rectangle = 16 Feet

Area of the triangle = (Length * Breadth)

                                 = (22 * 16)

                                 = 352 ft²

The Total Area of the Five Sided figure can be found by summing up the areas of the Triangles and the Rectangle.

The Total Area of the figure is 88 + 44 + 352 = 484 ft²

So, the total area of the figure is 484 ft².

The area of the trapezoid is 308 ft2, the correct option is D.

We are given that;

Shorter side= 16 feet

b2​=6+6=12 ft

Height= 22 feet

Now,

To find the area of a trapezoid, you need to know the lengths of the two parallel sides (the bases) and the height. The formula for the area of a trapezoid is:

A=21​(b1​+b2​)h

where b1​ and b2​ are the lengths of the bases and h is the height1.

Substitute these values into the formula and simplify:

A=21​(16+12)×22

A=21​×28×22

A=14×22

A=352

Therefore, by the area the answer will be 308 ft2.

Answer:

Step-by-step explanation:

1.84

2.32

3.30

4.88

1.

84 because PEMDAS(parenthesis/Exponents/Multiply/Divide/Add/Subtact) says you do parenthesis first. So you add 9 and 3 to get 12. The you do 12*7 to get 84.

Assign the numbers to the number line in the following order:

2.15=2.15

220%=2.2

9/4=2.25

*2.15* is easy enough to place as it is already in decimal form. However, the other 2 options need to be converted to decimals in order to be placed. We have the fraction 9/4 and percentage 220%. 9/4 can either be simply divided on a calculator or turned into the mixed fraction 2 and 1/4, which is *2.25*. Finally, we know that converting a decimal to a percentage we multiply the decimal by 100. Therefore, to convert a percentage to a decimal we divide 100 or move the decimal to the left 2 places. With this conversion rule, 220% transforms to *2.2* and we have the third and final number for our number line. Arranging these three numbers from least to greatest:

2.15, 2.2, 2.25

Given:

r = 8 in

h = 8 in

π = 3.14

Find:

V = ?? in³

\(\hrulefill\)

Now solving,

Substitute the given values into the formula:

=> V = (3.14)(8)²(8)

Using a calculator to simplify:

=> V = 1607.68 in²

Rounded to the nearest tenth:

∴ V ≈ 1607.7 in²

Thus, the first option is correct.
