Answer:

B thank you for doing that hard work

putting all that info in

Step-by-step explanation:

Answer:

write 9x+80=7x+120

next transpose the x values to one side and the number to other side

i.e 9x-7x=120-80

= 2x= 140

x=140/2

and you will get the answer 70

so x=70

Answer:460

Step-by-step explanation:on delta math

The total number of action figures in Genesis's collection will be 460.

It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that are +, -, ×, and ÷.

It is given that, Genesis offers a variety of action figures. She hangs the remainder and keeps some in a display cabinet. 253 of her action figures are hung on the wall, and the display case holds 45% of her collection.

The obtained expression for the given condition,

=253 / (1-0.45)

=253/0.55

=25300/55

=460

Thus, the total number of action figures in Genesis's collection will be 460.

Answer:

B

Step-by-step explanation:

Answer:

165 pounds

Step-by-step explanation:

3 times 7 = 21

186 - 21 = 165

Answer:

Side length:11

Area: 121

Step-by-step explanation:

if its a square all sides should be equal so you can divide 44 by 4 which gives you 11 and then to find area you just multiply the two sides together which would be 11x11 and that equals 121

I'm pretty sure this is what it would be but it also seems over simplified and i might be missing something?

Answer:

a. Ratio of their circumference = 2:3

b. The ratio of their surface areas = 2:3

c. The ratio of their volume = 4:9

Step-by-step explanation:

Let the cylinders be labelled as A and B respectively.

Diameter of cylinder A = 6 in,

its radius = [tex]\frac{diameter}{2}[/tex]

                = [tex]\frac{6}{2}[/tex] = 3 in

Diameter of cylinder B = 9 in,

its radius = [tex]\frac{diameter}{2}[/tex]

               = [tex]\frac{9}{2}[/tex]  = 4.5 in

Thus,

a. circumference of a circle = 2[tex]\pi[/tex]r

Circumference of cylinder A = 2[tex]\pi[/tex]r

                                               = 2 x [tex]\pi[/tex] x 3

                                            = 6[tex]\pi[/tex] in

Circumference of cylinder B = 2[tex]\pi[/tex]r

                                              = 2 x [tex]\pi[/tex] x 4.5

                                              = 9[tex]\pi[/tex]

Ratio of their circumference = [tex]\frac{circumference of cylinder A}{circumference of cylinder B}[/tex]

                                               = [tex]\frac{6\pi }{9\pi }[/tex]

                                               = 2:3

b. The surface area of a cylinder = 2[tex]\pi[/tex]rh

the surface area of cylinder A = 2[tex]\pi[/tex]rh

                                                  = 6[tex]\pi[/tex]h

the surface area of cylinder B = 2[tex]\pi[/tex]rh

                                                = 9[tex]\pi[/tex]h

The ratio of their surface areas = [tex]\frac{surface area of cylinder A}{surface area of cylinder B}[/tex]

                                                 = [tex]\frac{6\pi h}{9\pi h}[/tex]

                                                 = 2:3

c. Volume of a cylinder = [tex]\pi[/tex][tex]r^{2}[/tex]h

volume of cylinder A = [tex]\pi[/tex][tex]r^{2}[/tex]h

                                = [tex]\pi[/tex] x [tex]3^{2}[/tex] x h

                                = 9[tex]\pi[/tex]h

volume of cylinder b = [tex]\pi[/tex][tex]r^{2}[/tex]h

                                    = [tex]\pi[/tex] x [tex]4.5^{2}[/tex] x h

                                    = 20.25[tex]\pi[/tex]h

The ratio of their volume = [tex]\frac{volume of cylinder A}{volume of cylinder B}[/tex]

                                         = [tex]\frac{9\pi h}{20.25\pi h}[/tex]

                                         = 4:9

Answer:

The straight-line distance between the points is approximately 8.6.

Step-by-step explanation:

The straight-line distance ([tex]d[/tex]) between the points is determined by the following Pythagorean identity:

[tex]d = \sqrt{x^{2}+y^{2}}[/tex] (1)

Where:

[tex]x[/tex] - Horizontal distance between the points.

[tex]y[/tex] - Vertical distance between the points.

Let consider that each square has a distance of 1 unit. If we know that [tex]x = 5[/tex] and [tex]y = -7[/tex], then the straight-line distance is:

[tex]d = \sqrt{5^{2}+(-7)^{2}}[/tex]

[tex]d \approx 8.6[/tex]

The straight-line distance between the points is approximately 8.6.

Answer:

648

Step-by-step explanation:

Answer:

C. At the 0.01 level of significance, the mean mass of the apples grown in the farmer's orchard is different from 100g.

Step-by-step explanation:

The null hypothesis is:

[tex]H_{0} = 100[/tex]

Because of the claim of the farmer.

The alternate hypothesis is:

[tex]H_{1} \neq 100[/tex]

The alternate hypothesis tests the farmer's claim at a significance level.

The results are calculated to be statistically significant at the 0.01 level.

This means that at the 0.01 level, the null hypothesis is rejected, that is, the mean mass of the farmer's orchard is different from 100. Since it is significant at the 0.01 level, it will be significant at the 0.05, 0.1, and increasing levels. So the correct answer is given by option C.

Step-by-step explanation:

The formula is given by :

[tex]s=\dfrac{m}{360}\times 2\pi r[/tex]

We have,

m = 19° and d = 9 cm

So,

[tex]s=\dfrac{19}{360}\times 2\pi \times \dfrac{9}{2}\\\\s=1.49[/tex]

Hence, this is the required soltion.

Answer:

C. progressive taxation

Step-by-step explanation:

Taxation can be defined as the involuntary or compulsory fees levied on individuals or business entities by the government to generate revenues used for funding public institutions and activities.

There are three (3) types of taxation used by the government, these are;

1. Regressive taxation: it involves charging individuals with low incomes a higher percentage of their total income and vice-versa.

- For instance, John pays 15% on $60,000 and Joyce pays 20% on $36,000.

2. Proportional taxation: it involves charging both lower and higher income earners equally in proportion to their income.

- For instance, John pays 20% on $50,000 and Joyce pays 20% on $36,000.

3. Progressive taxation: it involves charging individuals having higher incomes a higher percentage of their total income.

- For instance, John pays 30% on $70,000 and Joyce pays 10% on $45.000.

Hence, if employees who make more money pay a higher percentage of their income to the government, this is known as progressive taxation.

Answer:

a=3; (3,5) and (4,0) for the graph  

Step-by-step explanation:

ax-y=4

x=3, y=5 so...

a(3)-5=4

3a-5=4

+5 +5

3a=9

/3 .  /3

a=3

For the graph, use (3,5) and substitute x and y for anything:

ax-y=4

if x=0...

a(0)-y=4

-y=4

y=4

a=3; (3,5) and (4,0) for the graph!  

Answer:

The pooled estimate of the common variance is approximately 639.59

Step-by-step explanation:

The given parameters are;

The number of shops Emily visited, n₁ = 12 shops

The average repair estimate Emily was given, [tex]\overline x_1[/tex] = $85

The standard deviation of the estimate Emily was given, s₁ = $28

The number of shops John visited, n₂ = 9 shops

The average repair estimate John was given, [tex]\overline x_2[/tex] = $65

The standard deviation of the estimate John was given, s₂ = $21

The pooled estimate of the common variance, [tex]s_p^2[/tex], is given as follows;

[tex]s_p^2 = \dfrac{(n_1 - 1)\cdot s_1^2+(n_2 - 1)\cdot s_2^2}{n_1 + n_2-2}[/tex]

[tex]\therefore s_p^2 = \dfrac{(12 - 1)\cdot 28^2+(9 - 1)\cdot 21^2}{12 + 9-2} = 639.578947368[/tex]

∴ The pooled estimate of the common variance, [tex]s_p^2[/tex], ≈ 639.59
