Answer:

x = - 7.5

Step-by-step explanation:

Given:

[tex]\frac{1}{5}x+\frac{1}{4}=\frac{1}{2}\left(x+5\right)[/tex]

Solution~:

[tex]\frac{1}{5}x+\frac{1}{4}=\frac{1}{2}\left(x+5\right)[/tex]

Distribute:

[tex]\frac{1}{5}x+\frac{1}{4}=\frac{1}{2}x+\frac{5}{2}[/tex]

Subtract 1/4 from both sides:

[tex]\frac{1}{5}x+\frac{1}{4}-\frac{1}{4}=\frac{1}{2}x+\frac{5}{2}-\frac{1}{4}[/tex]

[tex]\frac{1}{5}x=\frac{9}{4}+\frac{1}{2}x[/tex]

Subtract 1/2x from both sides:

[tex]\frac{1}{5}x-\frac{1}{2}x=\frac{9}{4}+\frac{1}{2}x-\frac{1}{2}x[/tex]

[tex]-\frac{3}{10}x=\frac{9}{4}[/tex]

Multiply both sides by 10:

[tex]10\left(-\frac{3}{10}x\right)=\frac{9\cdot \:10}{4}[/tex]

[tex]-3x=\frac{45}{2}[/tex]

Divide both sides by -3:

[tex]\frac{-3x}{-3}=\frac{\frac{45}{2}}{-3}[/tex]

x = -15/2

x = -7.5

Which of these is not a very good example of a command economy?
a.)China
b.)Soviet Union
c.)United States during WWII
d.)United States today

Answers

(d) the Present United States is not a good example of a command economy.

A command economy is a crucial component of a political system in the economy in which the degree of output that is permitted and the prices that may be paid for goods and services are set by a central governing body. Most industries are owned by the public.

The principal alternative to a command economy is a free market b where supply and demand determine prices and output.

A communist political system includes a command economy, whereas capitalist countries have a free market.

Cuba, North Korea, and the former Soviet Union all have command economies. Up until 1978, when it started to shift to a mixed economy that combines communist and capitalist features, China maintained a command economy. A socialist market economy has been used to characterize its existing setup.

The central government of a country must possess and manage the means of production in a command economy, commonly referred to as a planned economy.

There is no private ownership of land or capital, or it is very restricted. Prices are determined by central planners, who also manage production levels and restrict or forbid competition in the private sector. There is no private sector in a command economy because all companies are owned by or under the supervision of the central government.

Government officials establish national economic priorities in a command economy, such as when and how to promote economic growth, how to share resources, and how to disperse the produce. This frequently takes the shape of a long-term plan.

Hence, the United States today is not a very good example of a command economy.

What are the relations in a right triangle?

The relations in a right triangle are given as follows:

The sine of an angle is given by the length of the opposite side to the angle divided by the length of the hypotenuse.The cosine of an angle is given by the length of the adjacent side to the angle divided by the length of the hypotenuse.The tangent of an angle is given by the length of the opposite side to the angle divided by the length of the adjacent side to the angle.

Using the Pythagorean Theorem, the hypotenuse of the triangle is given as follows:

Answers

We get the equation in terms of n as n = s / 4 - v.

Equation:

An equation is an expression with an equal sign.

For example:

3 x + 4 y = 5

2 x + 5 y = 9 etc.

We are given an equation:

s = 4 n + 4 v

We have to solve this for n.

First we will subtract 4 v from both sides:

s - 4 v = 4 n + 4 v - 4 v

s - 4 v = 4 n

4 n = s - 4 v

Now divide both the sides by 4:

4 n / 4 = (s - 4 v) / 4

n = s / 4 - v

Therefore, we get the equation in terms of n as n = s / 4 - v.

What is inductive reasoning?

Inductive reasoning entails drawing broad generalizations based on a small number of observations, and the conclusion is not necessarily guaranteed to be correct, but simply likely based on the data.

The argument presented is an example of inductive reasoning, because it is based on a specific observation and a generalization that goes beyond the available evidence.

While the previous and current mayors may be honest, based on this limited evidence, it is not necessarily true that all mayors are honest.

What is a histogram?

A histogram is a graph that shows the frequency of numerical data using blocks. The height of a cube( the perpendicular axis) represents the distribution frequency of a variable( the quantum, or how frequently that variable appears). A histogram is a graphical display of data using bars of different heights. In a histogram, each bar groups figures into ranges. high bars show that further data falls in that range. A histogram displays the shape and spread of nonstop sample data. Histograms fantasize quantitative data or numerical data, whereas bar maps display categorical variables.

From the frequency table, we get the frequency of the first class is 20(twenty), and for the second(2) class it is 10(ten) also the remaining frequencies are correctly shown by the histogram shown in option C.

Hence, C is the correct(right) answer.

find the quotient 17 ÷ 6 8/10​

Answers

The ratio of EQUATION the outcome is (17/6)/(8/10) = 3.5416667.

What in mathematics is a quotient?

The quotient is the result of dividing two numbers by each other. As in the case of 8 4 = 2, when the division produced the number 2, the outcome is the quotient. The dividend is 8 and the divisor is 4.

based on the available facts;

Divide: 17/6 : 8/10

= 17/6· 10/8

= 17 · 10/6 · 8

= 170/48

= 85/ 24

= 85/24

When two fractions are divided, the first fraction is multiplied by the second fraction's reciprocal value. Finding the reciprocal of the second fraction is the first sub-step. For example, the reciprocal of 8/10 is 10/8. Multiply the two numerators after that. Multiply the two denominators after that. The intermediate step that comes after canceling by a common factor of 2 yields 85/24.

Therefore, eight tenths of seventeen sixths equal eighty-five twenty-fourths.

3. Clearcut Lumber sells its dimensional lumber with a markup of 60%
What rate of margin do they use?
A batch of plywood sells for $500 what was the cost?
Fence posts with a cost of $10 would sell for how much?
The gross profit on the sale of some 4 by 4's was $50 what was the selling price?

Answers

The rate of margin used is 37.5% . The cost price of the batch of plywood is $312.5. Fence post sell for $16. The selling price was $133.33

Margin is the difference between the Selling price and the cost price. The price at which a item is sold is called the selling price and the price at which an item is bought is called the cost price.

The given markup is 60%.

We know that margin=markup÷(1+markup)

markup=60%

Substituting the values we get the rate of margin:

[tex]=\frac{\frac{60}{100} }{1+\frac{60}{100} } \\=\frac{60}{160}\\ =37.5[/tex]

Hence the rate of margin is 37.5 %.

Selling price for the plywood=$500

We know that selling price=cost price ÷(1-margin)

Let the cost price be x

[tex]x=500(1-\frac{37.5}{100} )\\x=312.50[/tex]

The cost price is $ 312.50 .

Now cost of fence = $10

Selling price of fence=cost price÷(1-margin)

substituting the values we get:

Selling price =10÷0.625

or, selling price= $16

Therefore the selling price is $16 .

Now we know that Markup percentage= profit÷ cost price

Substituting the values we get:

[tex]60\% = \frac{50}{CP}\\or,\frac{60}{10}=\frac{50}{CP}\\or,CP=83.33[/tex]

Therefore sell price=cost price+ profit

or, sell price=83.33+50

or, sell price =133.33

The sell price is $133.33

Use m for the numbers of minutes of phone use in a month, and solve your inequality for m.

Answers

Step-by-step explanation:

sadly you skipped the key word in the question.

should we check under what circumstances plan A costs more than plan B ? or costs less than plan B ?

so, I don't know which inequality to solve.

but I can tell you the facts, and you need to pick the right direction for your answer.

cost of plan A for used minutes m :

cA(m) = 1.9 + 0.06m

plan B

cB(m) = 0 + 0.07m = 0.07m

to find the intersecting point, where both plans cost the same :

1.9 + 0.06m = 0.07m

1.9 = 0.01m

m = 1.9 / 0.01 = 190 minutes

up until 190 minutes plan B is cheaper.

if there are more than 190 minutes, than plan A is cheaper.

so,

m < 190 B is cheaper

m > 190 A is cheaper

m = 190 A and B cost the same

What is Euclid's Division Lemma ?

The Euclid's Division Lemma says when a number 'a' is divided by a number 'b' gives the quotient to be 'q' and the remainder to be 'r' then the following relation -> a = bq + r exists, where 0 ≤ r < b.

Dividend [a] = Divisor [b] × Quotient [q] + Remainder [r]

Given two numbers A = - 210 and B = - 15

The resultant quotient when A is divided by B can be calculated using Euclid's division lemma. Initially, we will assume remainder [r] = 0.

If the quotient is in decimals, we will change the remainder according to it else if the quotient is a whole number, the remainder will remain 0.

Using Euclid's division lemma -

Dividend [a] = Divisor [b] × Quotient [q] + Remainder [r]

- 210 = - 15 x q + 0

- 210 = - 15 x q

q = - 210 / - 15 = 14

Since, the quotient is a whole number, the remainder will remain zero.

Therefore, the quotient of A = - 210 and B = - 15 is 14.
