The equation he should you use to find the final number of moles of gas in the balloon after the deflation is n1/v1 = n2/v2

The molarity of a solution is the ratio of the mole of the substance to its volume

Since the mole "n" is directy proportional to the volume, hence;

n = kv
k = n/v

Hence the equation he should you use to find the final number of moles of gas in the balloon after the deflation is n1/v1 = n2/v2

To find :-

More valuable packet of beans

Given :-

500g packet of beans = £114

125g packet of beans = £28

Solution :-

We will find out value of 100g of beans of each packet, then we will compare the value, the less will be the value, the more valuable packet is it.

Packet 1

500g of beans = £114

100g of beans

[tex] = \frac{114}{500} \times 100 \\ = \frac{114}{5} \\ = 22.8[/tex]

The 100g beans of packet 1 will cost £22.8.

Packet 2

125 g of beans = £28

100g of beans

[tex] = \frac{28}{125} \times 100 \\ = \frac{28}{5} \times 4 \\ = 5.6 \times 4 \\ = 22.4[/tex]

The 100g beans of packet 2 will cost £22.4.

Result :-

The packet 2, 125g for £28 is more valuable than packet 1, 500g for £114.

Answer:

the 125 gm packet

Step-by-step explanation:

Find the unit rate of each

1.14 /500 g = .00228  per gram

.28/128 g  = .0021875 per gram   <=====this is the better value  (costs less per gram)

Answer:

The answer is C.

Step-by-step explanation:

3.844 X 10 w/ power of 5= 384400

2 X 10 w/ power of 3= 2000

2000 x 384400= 768800000

7.688 x 10 w/ power of 5 = 768800

Answer:

Jupiter to Sun = 7.688 * 10⁸km

Jupiter to Sun = 2 * 10³ times Earth to Moon

Substitute 3.844 * 10⁵km for Earth to Moon

Jupiter to Sun = 2 * 10³ *  3.844 * 10⁵km

Jupiter to Sun = 2 *  3.844 * 10³ * 10⁵km

Jupiter to Sun = 7.688 * 10³ * 10⁵km

Jupiter to Sun = 7.688 * 10⁸km

Therefore, the answer would be C. 7.688 * 10⁸km

The space inside the steps will be 0.04 cubic meter

The space in a three dimensional region occupied by any body is called as volume.

Assume the steps have the dimensions shown in the diagram below.

We can decompose them into two rectangular prisms.

The lower prism has the dimensions 20 in × 16 in × 6 in.

The upper prism has the dimensions 20 in ×   8 in × 6 in.

1. Volume of lower prism

V = lwh = 20 in × 16 in × 6 in = 1920 in³

2. Volume of upper prism

V = lwh = 20 in × 8 in × 6 in = 960 in³

3. Volume of steps

V = 1920 in³ + 960 in³ = 2880 in³

Or the volume in meter will be 2880 cubic inches = 0.04 cubic meters.

The measure of the angle ∠ABC is 110° and the measure of the reflex angle ∠CBD is 70°.

Angle is the space between the line or the surface that meets.  And the angle is measured in degree. For complete 1 rotation, the angle is 360 degrees.

Linear angle - If the total of two angles is 180 degrees, they are said to be linear angles.

The measure of the angle ABC will be

∠ABC = 110°

The angle ∠ABC and ∠CBD are the linear angles. Then we have

∠ABC + ∠CBD = 180°

Answer:

Option A

Step-by-step explanation:

Given expression:

Option A

⇒ (x - 4)(3x + 2)

⇒ (x × 3x) + (2 × x) + (-4 × 3x) + (-4 × 2)

⇒ (3x²) + (2x) + (-12x) + (-8)

⇒ 3x² + 2x - 12x - 8

⇒ 3x² - 10x - 8

3x² - 10x - 8 = 3x² - 10x - 8 (Yes!)

Option B

⇒ (3x - 4)(x - 2)

⇒ (3x × x) + (3x × -2) + (-4 × x) + (-4 × -2)

⇒ (3x²) + (-6x) + (-4x) + (8)

⇒ 3x² - 6x - 4x + (8)

⇒ 3x² - 10x + 8

3x² - 10x - 8 = 3x² - 10x + 8 (No!)

Option C

⇒ (3x - 4)(x + 2)

⇒ (3x × x) + (3x × 2) + (-4 × x) + (-4 × 2)

⇒ (3x²) + (6x) + (-4x) + (-8)

Answer:

Hi! Let's find which expression is equivalent to [tex]3x^{2} - 10x - 8[/tex]. First, remember that expressions are equivalent when they have identical solutions or roots. That means we have to do three things:

- solve [tex]3x^{2} - 10x - 8[/tex]

- review the listed expressions

- determine which solution is equivalent to the solution of [tex]3x^{2} - 10x - 8[/tex]

First, let's solve [tex]3x^{2} - 10x - 8[/tex].

Use the sum-product pattern -

3x^2 - 10x - 8

3x^2 + 2x - 12x - 8

Common factor from the two pairs -

3x^2 + 2x - 12x - 8

x(3x + 2) - 4(3x + 2)

Rewrite in factored form -

x(3x + 2) - 4(3x + 2)

(x - 4)(3x + 2)

Now, let's review the listed expressions. We have:

A. (x - 4)(3x + 2)

B. (3x - 4)(x - 2)

C. (3x - 4)(x + 2)

D. (3x - 2)(x + 4)

We're looking for one of these expressions to be equivalent to the solution of [tex]3x^{2} - 10x - 8[/tex], which we know is (x - 4)(3x + 2). The first choice, A. (x - 4)(3x + 2), would be our answer!

The error which Loren made was C. she should have solved 149 = startfraction 19 over 9 endfraction (10) b for b.

This refers to those miscalculations or misjudgments about a situation or a mathematical solution to give wrong values.

Hence, because Loren is solving an equation of 0 = startfraction 19 over 9 endfraction (149) b for b to find the equation of a trend line that passes through the points (1, 130) and (10, 149), the error she made was option C.

Answer:

2916 square inches

Step-by-step explanation:

Surface area of rectangular prism:

Here, area of the top of the prism is not included.

l = 24 in ; b = 20 in ; h = 16 in

Surface area = lb + 2bh + 2lh

                    = 24 * 20 + 2*20*16 + 2*24 *16

                    = 480 + 640 + 768

                    = 1888 sqaure inches

Surface area of triangular prism:

length = 24 in ; a = b = 16 in  ;  base = 20 in and height = 13 in

[tex]\sf \text{Base area=$2*\dfrac{1}{2}*base *height = base *height$}[/tex]

                = 20 * 13

                  = 260 square inches

Surface area = length*(a +b) + base area

                     = 24*(16+16) + 260

                     = 24 * 32 + 260

                      = 768 + 260

                      = 1028 square inches

Surface area of composite figure = 1888 + 1028

                                                          = 2916 square inches

Answer:

Mean = 75

Median = 73.5

Mode = 95

Range = 36

Step-by-step explanation:

Given:

Sort:

To find:

Mean:

[tex]\displaystyle \large{\dfrac{1}{n}\sum_{i =1}^n x_i = \dfrac{x_1+x_2+x_3+...+x_n}{n}}[/tex]

Sum of all data divides by amount.

[tex]\displaystyle \large{\dfrac{59+60+70+77+89+95}{6}=\dfrac{450}{6}}\\\\\displaystyle \large{\therefore mean=75}[/tex]

Therefore, mean = 75

Median:

If it’s exact middle then that’s the median. However, if two data or values happen to be in middle:

[tex]\displaystyle \large{\dfrac{x_1+x_2}{2}}[/tex]

From 59,60,70,77,89,95, since 70 and 77 are in middle:

[tex]\displaystyle \large{\dfrac{70+77}{2} = \dfrac{147}{2}}\\\displaystyle \large{\therefore median = 73.5}[/tex]

Therefore, median = 73.5

Mode:

The highest value or/and the highest amount of data. Mode can have more than one.

From sorted data, there are no repetitive data nor same data. Consider the highest value:

Therefore, mode = 95

Range:

[tex]\displaystyle \large{x_{max}-x_{min}}[/tex] or highest value - lowest value

Thus:

[tex]\displaystyle \large{95-59 = 36}[/tex]

Therefore, range = 36

(d + 3) would be 10

Step-by-step explanation:

Step 1:  Distribute

[tex]4.5(d + 3) = 45[/tex]

[tex](4.5 * d) + (4.5 * 3) = 45[/tex]

[tex]4.5d + 13.5 = 45[/tex]

Step 2:  Subtract 13.5 from both sides

[tex]4.5d + 13.5 - 13.5 = 45 - 13.5[/tex]

[tex]4.5d = 31.5[/tex]

Step 3:  Divide both sides by 4.5

[tex]\frac{4.5d}{4.5} = \frac{31.5}{4.5}[/tex]
