How many times does 27 go into 70?

The nature of the graph from point A to B : The graph increases, then decreases.

Given,

Graph is x -y coordinates.

Now,

Graph is concave downwards.

Coordinates of point A : (0,0)

Coordinates of point B : (6,0)

So,

The graph firstly increases from x = 0 to x = 3.

Then,

The graph decreases from x = 3 to x = 6 .

Therefore the graph increases and then decreases.

Thus option D is correct.

The solution to the equation a+5=-5a+5 is a=0.

We are given that;

The expression a+5=-5a+5

Now,

To solve the equation a+5=-5a+5, we need to isolate the variable a on one side of the equation.

We can do this by adding 5a to both sides of the equation:

a + 5 + 5a = -5a + 5 + 5a

Combining like terms gives:

6a + 5 = 5

Subtracting 5 from both sides of the equation gives:

6a = 0

Dividing both sides of the equation by 6 gives:

a = 0

Therefore, by algebra the answer will be a=0.

Answer:The standard deviation is about 3.6.

Step-by-step explanation:

According to the Range Rule of Thumb  : The range is about four times the standard deviation.

Answer:

42 that's ur answer u just multiply all the numbers

The multiplication of 3, 7, and 2 (which are all prime numbers) equals to 42. Therefore, 42 is the number which has a prime factorization of 2, 3, and 7.

The product of 3 x 7 x 2 gives us the number for which this is the prime factorization. The prime factorization of a number is the breaking down of that number into its simplest factors that are prime numbers, in this case, it would be 2, 3, and 7. By multiplying these number together: 3 x 7 x 2, we get the number 42, hence, 42 is a number we are looking for.

Mari has 42 coins consisting of nickels, dimes, and quarters. The total value of the coins is $9.35. The number of dimes is one less than three times the number of nickels. Mari has 17 nickels, 8 dimes, and 17 quarters.

Let's use algebraic equations to solve this problem.

Let "n" be the number of nickels, "d" be the number of dimes, and "q" be the number of quarters.

We have three pieces of information from the problem:

1. The total number of coins: n + d + q = 42

2. The total value of the coins: 0.05n + 0.10d + 0.25q = 9.35

3. The number of dimes is one less than three times the number of nickels: d = 3n - 1

Now, let's substitute the third equation into the first equation to express "d" in terms of "n":

(3n - 1) + n + q = 42

4n + q = 43

q = 43 - 4n

Next, we'll substitute the values of "q" and "d" into the second equation:

0.05n + 0.10(3n - 1) + 0.25(43 - 4n) = 9.35

0.05n + 0.30n - 0.10 + 10.75 - n = 9.35

0.35n + 10.65 = 9.35

0.35n = 9.35 - 10.65

0.35n = -1.30

n = -1.30 / 0.35

n ≈ 3.71

Since the number of coins can't be a fraction, we'll round down to the nearest whole number. Therefore, Mari has 3 nickels.

Now, let's find the number of dimes:

d = 3n - 1

d = 3(3) - 1

d = 9 - 1

d = 8

Finally, we can find the number of quarters using the equation for "q":

q = 43 - 4n

q = 43 - 4(3)

q = 43 - 12

q = 31

In conclusion, Mari has 3 nickels, 8 dimes, and 31 quarters.

Answer:

In year 2030 the population is predicted to be 71.75 million

Step-by-step explanation:

* Lets explain how to solve the problem

- Using data from 2010 and projected to 2020, the population of

 the United Kingdom (y, in millions) can be approximated by the

 equation  10.0 y − 4.55 x = 581

- x is the number of years after 2000

- We need to know in what year the population is predicted to be

  71.75 million

* Lets substitute the value of y in the equation by 71,75

∵ The equation of the population is 10.0 y - 4.55 x = 581

∵ y = 71.75

∴ 10.0(71.75) - 4.55 x = 581

∴ 717.5 - 4.55 x = 581

- Subtract 717.5 from both sides

∴ - 4.55 x = - 136.5

- Divide both sides by - 4.55

∴ x = 30

∵ x represents the number of years after 2000

∵ 2000 + 30 = 2030

∴ In year 2030 the population is predicted to be 71.75 million

Final answer:

The population of the United Kingdom is predicted to be 71.75 million in the year 2030, calculated by substituting the given population value into the equation and solving for the year.

Explanation:

To find the year in which the population of the United Kingdom is predicted to be 71.75 million, you can use the given equation 10.0y - 4.55x = 581. Here, x is the number of years after 2000, and y is the population in millions.

First, substitute y with 71.75:

Now, add the number of years, x, to the base year, 2000:

Therefore, the population of the United Kingdom is predicted to be 71.75 million in the year 2030.
