Answer:

≈ 11.4

Step-by-step explanation:

Calculate the distance using the distance formula

d = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]

with (x₁, y₁ ) = (8, 7) and (x₂, y₂ ) = (1, - 2)

d = [tex]\sqrt{(1-8)^2+(-2-7)^2}[/tex]

   = [tex]\sqrt{(-7)^2+(-9)^2}[/tex]

   = [tex]\sqrt{49+81}[/tex]

   = [tex]\sqrt{130}[/tex]

   ≈ 11.4 ( to the nearest tenth )

The best trading partner for a country depends on complementary resources and needs, and a country that specializes in producing the goods that another country has a high demand for can be a good trading partner.

A trading partner is a nation or other organization with which another nation conducts trade, frequently through the exchange of products and services, in the context of international trade. Trading partners can be crucial for a nation's economy since they open up doors to new markets, boost exports, and create chances for expansion.

A good trading partner should have resources and needs that are compatible with those of other nations. A nation that excels in producing oil, for instance, would be a suitable trading partner for nations that have a strong need for oil but may not be able to supply it itself.

Similarly to this, a nation that specializes in manufacturing cars would make an excellent trading partner for nations that have a strong demand for cars but might not be able to create them on their own.

These findings suggest that choices A and C are less likely to be the greatest trading partners for all three countries since they only take into account the requirements of one or two of them.

A country in Option B, which specializes in oil production, might make an excellent trading partner for nations with significant oil demand.

Option D, a nation that specializes in manufacturing cars, might make an excellent trading partner for nations with a high demand for cars.

It is challenging to decide which choice would be the ideal trading partner for all three countries without more details about the unique needs and resources of the nations on the table.

Answer:

36 girls in the class

Answer:

12 girls are in the classroom.

Step-by-step explanation:

We find out that the ratio is 3:4 based upon the question.

If there's 9 boys then the ratio is incomplete however you just need complete it based on the information given.

So, 3:4

      9:?

9 / 3 = 3

4 x 3 - 12 girls

Thus, there being 12 girls in the classroom.

To check:

9:12;

9 / 3 = 3

12 / = 4

So the ratio still ends up being 3:4 therefore 9:12 is equivalent and correct!

Question is ;

Complete question is;

Boston , Massachusetts, and buffalo, New York, are hit by snowstorms that last 3 days . Boston accumulates snow at a rate of 1.5 feet every 36 hours. Buffalo accumulates snow at a rate of 0.01 inches every minute.

Which city accumulates more snow in 3 days? How much more snow?

Answer:

- Boston accumulates more snow in 3 days.

- It accumulates 0.6 ft of snow more than Boston

Step-by-step explanation:

Boston accumulates 1.5 feet of snow every 36 hours.

Number of hours in 3 days = 24 × 3 = 72 hours.

Thus, In 72 hours, Boston would have accumulated; (1.5 × 72)/36 = 3 feet of snow.

Now, Buffalo accumulates 0.01 inches of snow every minute.

In 3 days, number of minutes we have = 60 × 24 × 3 = 4320 minutes

Thus, total snow accumulated in 3 days = 0.01 × 4320/1 = 43.2 inches

Now, let's convert this to ft;

12 inches = 1ft

Thus; 43.2 inches = 43.2 × 1/12 = 3.6ft

Thus, Buffalo accumulates more snow in 3 days.

It accumulates 0.6 ft of snow more than Boston

Given:

11 less than four times a number is the same as 46 less than the product of -1 and the number.

To find:

The missing number.

Solution:

Let x be the missing number.

Four times a number = 4x

11 less than four times a number = 4x-11

Product of -1 and the number = (-1)x

                                                 = -x

46 less than the product of -1 and the number = -x-46

The given statement is "11 less than four times a number is the same as 46 less than the product of -1 and the number". So,

[tex]4x-11=-x-46[/tex]

[tex]4x+x=11-46[/tex]

[tex]5x=-35[/tex]

Divide both sides by 5.

[tex]x=\dfrac{-35}{5}[/tex]

[tex]x=-7[/tex]

Therefore, the missing number is -7.

Step-by-step explanation:

To find how much Andrea started with, subtraction is needed. To subtract, we need to set up fractions;

[tex]4\frac{1}{3}-\frac{11}{4}[/tex]

[tex]4\frac{1}{3}=\frac{4\cdot 3+1}{3}[/tex]

[tex]=\frac{13}{3}[/tex]

[tex]=\frac{13}{3}-\frac{11}{4}[/tex]

Least common multiplier: 3,4 = 12

Adjust fractions based on the LCM

[tex]=\frac{52}{12}-\frac{33}{12}[/tex]

Apply the fraction rule: [tex]\quad \frac{a}{c}-\frac{b}{c}=\frac{a-b}{c}[/tex]

[tex]\frac{52}{12}-\frac{33}{12}=\frac{52-33}{12}[/tex]

[tex]=\frac{52-33}{12}[/tex]

Add the numbers: [tex]52-33=19[/tex]

[tex]=\frac{19}{12}[/tex]

[tex]\frac{19}{12}=1\frac{7}{12}[/tex]

[tex]=1\frac{7}{12}[/tex]

Therefore, Andrea started with [tex]1\frac{7}{12}[/tex] yard material.

Answer:

The 50th term of the sequence that begins with - 6 is 288.

Step-by-step explanation:

An arithmetic progression, also known as an arithmetic sequence, is a set of numbers in which the difference between successive terms remains constant. The sequence 5, 7, 9, 11, 13, 15,... is, for example, an arithmetic progression with a common difference of 2.

Formula -[tex]$a_{n}=a_{1}+(n-1) d$[/tex]

It is in arithmetic progression as the common difference between all consecutive numbers is 6.

Let a1 be the first term and d be the common difference.

Therefore, a1 = - 6 and d = 6

For 50th term, a50 = a1 + (n - 1) d

= - 6 + (50 - 1) 6

= - 6 + 49 × 6

= - 6 + 294

= 288

Thus, the 50th term of the sequence is 288.

Step-by-step explanation:

X^2 and 9 are two squares, while 6 can be obtain my multiplying x and 3 by 2.

so this is a square of a binomial

(x+3)^2

or

(x+3)(x+3)

Answer:

(x+3)², if looking for x, X = -3

Step-by-step explanation:

X²+6x+9 is a perfect square as you immediately can see that 3+3 = 6 and 3*3 = 9.

I used the generic rectangle to solve it, 9 into top right corner and then x² onto the bottom left, multiplying eachother to get 9x² which is formed by 3x and 3x multiplied so you would have (x+3) (x+3).

Step-by-step explanation:

Assuming you meant "hundredth", for the nearest hundredth term you would need to round up to the 2nd number behind the decimal.  The thousandth digit of the number is 9, since 9 is greater than 4, you would need to round up by 1 to get 958.99.

4) [tex]-\frac{2}{3}[/tex]

Step-by-step explanation:

Taking the cube root of a number is the same as finding what number times itsef three times equals the number under the radical sign.

[tex]\sqrt[3]{-1}[/tex]

[tex]=-1[/tex]

Since (-1) times itself, three times equals (-1).

[tex]\sqrt[3]{-\frac{8}{27}}[/tex]

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

Since ([tex]-\frac{2}{3}[/tex]) times itself three times equals ([tex]-\frac{2}{3}[/tex]).
