second q: a girl had 12 coins. they were made of $2 coins and $1 coins. together she had $16, how many $2 coins did she have?

Answer:

Total number of copies sold to date = 361628.

Step-by-step explanation:

Let the number of copies sold to date = a

It's given that number of copies sold in the first month = 31100

These copies were 8.6% of the number of copies sold to date.

Therefore, 8.6% of a = 31100

a × [tex]\frac{8.6}{100}=31100[/tex]

a = [tex]\frac{31100}{0.086}[/tex]

a = 361627.907

a ≈ 361628

Therefore, total number of copies sold to date = 361628.

Answer:

Side length = 5 root 2

perimeter is (5 root 2)*3

Step-by-step explanation:

Use pythagoras

a^2 = b^2 + c^2

a^2 = 5 root 2

(5 root 2)^2 = (c^2)/2 + c^2

75 = (c^2)/2 + c^2

150 = c^2 + 2c^2

150 = 3c^2

50=c^2

root of 50 = 5 root 2

as it is equiliateral triangle all sides are the same

Answer:

Side: 10

Perimeter: 30

Step-by-step explanation:

An equilateral triangle has a height of 5√3. What is the length of each side in the equilateral triangle? What is the perimeter of the equilateral triangle?

In triangles with angles with 30°, 60°, and 90°, the hypotenuse (the angle opposite to the 90° angle) is twice as long as the base, and the height is √3 times as long as the base. To make it easier, this is a list of the sides:

x = base

√3 * x = height

2x = hypotenuse.

Look at the drawing I have attached below

If AD is the base of the triangle ADC, then CD, the height is √3 times AD. If we set AD as x, CD = √3*x = 5√3

√3*x = 5√3

Divide both sides by √3.

x = 5

Then, because altitudes in equilateral triangles bisect the base (CD cuts AB in half), then AB = 10.

The sides in equilateral triangles are equal, so each side is 10.

Then, the perimeter must be 30.

I hope this helps! Feel free to ask any questions!

Answer: No.

Step-by-step explanation:

They aren't equal because using the order of operations, the two in 7n-2 is subtracted from 7n. In 2-7n, they are subtracting 7n from 2, which would give a totally different answer.

Answer:

no they are not the same or equal. this is because the first part of the expression 2 is the number that is negative while 7n is positive. in the second half of the expression 2 is positive and 7n is negative.

Answer:

B is correct. Your starting amount is 210$ And you're taking away 15$ each time she uses the club,x.

Step-by-step explanation:

Answer:

The linear function model the situation is b = 210 - 15x .

Option (B) is correct .

Step-by-step explanation:

Let us assume that the number of times giselle uses the club be x .

As given

giselle pays $210 in advance on her account at the athletic club.

Each time she uses the club,$15 is deducted from the account.

Let suppose that the money left after giselle uses the club x times is b .

Than the equation becomes

Money left = Amount pay in advance - Deducted amount × Number of times  giselle uses the club .

Put all the values in the above

b = 210 - 15 × x

b = 210 - 15x

Therefore the linear function model the situation is b = 210 - 15x .

Option (B) is correct .

Answer:

¿Cumplirá Amelia con lo que se ha propuesto?

Amelia no cumple con lo que se ha propuesto, porque:

56,4 ÷ 2 = 28,2 ← 1 cucharadita

28,2 + 28.2 = 56,4 + 28,2 = 84.6 Cal ← 3 cucharaditas

84.6 Cal + 17 Cal azúcar = 101,6 Cal

101,6 Cal + 180 Cal pan = 281,6 Cal

Lo que se ha propuesto Amelia = 260 Cal

Lo que está consumiendo = 281 Cal

- Además, si Amelia solo quiere echarse ¾ de una porción de Nesquik, entonces, ¿Cuántas cucharaditas echará a su taza?

¾ × 2 = 1,5 ← cucharaditas

Se echara 1,5 cucharaditas :D

Step-by-step explanation:

Answer:

See below.

Step-by-step explanation:

1.

5^2 + 12^2 = x^2

25 + 144 = x^2

169 = x^2

x = 13

2.

3^2 + x^2 = [sqrt(10)]^2

9 + x^2 = 10

x^2 = 1

x = 1

3.

1^2 + x^2 = 4^2

1 + x^2 = 16

x^2 = 15

x = sqrt(15)

4.

[sqrt(27)]^2 + x^2 = 6^2

27 + x^2 = 36

x^2 = 9

x = 3

5.

15/5 = c/sqrt(29)

5c = 15 * sqrt(29)

c = 3sqrt(29)

Answer:

21 and 8, respectively

Step-by-step explanation:

7/10 of 30 is (7 x 30)/10 = 210/10 = 21

Alternatively, 7/10 = (3 x 7)/30, since 30 = 3 x 10

4/5 of 10 is (4 x 10)/5 = 40/5 = 8

Alternatively, 4/5 = (2 x 4)/10, since 10 = 2 x 5

Answer:

A. f(x) = 9sin(x/3) + 6

Step-by-step explanation:

First, we can eliminate B and C because they have the wrong vertical shift.

Since the y intercept is 6, this means the function has a vertical shift up 6 units, represented by a +6 at the end of the equation.

The amplitude is 9, found by calculating the difference between the minimum and maximum values, and dividing it by 2.

(15 - (-3)) / 2

18 / 2

= 9

Using a calculator, find the period given the frequency.

The period (coefficient of x) is 1/3.

So, putting all of these constants together, the correct equation is:

A. f(x) = 9sin(x/3) + 6

Answer:

A. f(x) = 9sin(x/3) + 6

Answer: So the answer is BStraight lines are produced by linear functions. That means that a straight line can be described by an equation that takes the form of the linear equation formula thats one thing i found online

Step-by-step explanation: use this formula y=mx +b/. Here's one more thing that can be useful; The graph below represents any line that can be written in slope intercept form. It has two slider bars that can be manipulated. The bar labeled m lets you adjust the slope, or steepness, of the line. The bar labeled b changes the y-intercept. Try sliding each bar back and forth, and see how that affects the line.
