Answer:

6a2-3ax+3a

Step-by-step explanation:

Answer:

Step-by-step explanation:

3a(2a-x+1)

= 6a² - 3ax + 3a

(5x-3) - 7(x-2) = 2(4x+3) - 3(2x-4) + 1

5x - 3 - 7x + 2 = 8x + 6 - 6x + 4 + 1

-2x -1 = 2x + 11

-4x = 12

x = -3

Answer:

Step-by-step explanation:

Since the figure is a right angled triangle we can use trigonometric ratios to find measure of ∠A.

To find ∠A we use sine

sin ∅ = opposite / hypotenuse

From the question

the opposite is 13

the hypotenuse is 15

So we have

[tex] \sin(∠A) = \frac{13}{15} \\∠A = \sin ^{ - 1} ( \frac{13}{15} ) \\ ∠A = 60.0735651...[/tex]

We have the final answer as

∠A = 60.07°

Hope this helps you

Step-by-step explanation:

Hey there!

Here;

As the figure shown is a Right angled triangle. Taking refrence angle as angle A, we get,

p= 13

h = 15

In ratio of sin there is p and h, So using sin ratio.

[tex] \sin( \alpha ) = \frac{p}{h} [/tex]

Put all values.

[tex] \sin( \alpha ) = \frac{13}{15} [/tex]

Simplify it.

[tex] \sin( \alpha ) = 0.86666666[/tex]

[tex] \alpha = { \sin}^{ - 1} (0.8666666)[/tex]

[tex] \alpha = 60.0732°[/tex]

Therefore the measure of angle A is 60°.

Step-by-step explanation:

Answer:2.5

Step-by-step explanation:

The correct answer is B. 2.3.

For us to know the equivalent decimals of a fraction, you have to use the numerator as the dividend, and the denominator will be your divisor.

The equation will be:

2 + ( 1 / 3 )

2 + (0.33333333)

= 2.333333

If you'll have it rounded off, you'll get the answer 2.3.

Step-by-step explanation:

because its math and it makes sense

Answer:

Substitute the 2nd and 3rd equations for x and y into the first equation.

Use the distributive property to simplify terms

Combine like terms to get 12z = -24

Solve for z = -2

Solve for x and Y by substituting z into 2nd and 3rd equations

Step-by-step explanation:

2x - y + 3z = -12

x = 3 + 2z

y = -6 - 5z

Substitute;

2(3 + 2z) - (-6 - 5z) + 3z = -12

Distribute;

6 + 4z + 6 + 5z + 3z = -12

Combine like terms;

12 + 12z = -12

Subtract 12 from both sides;

12z = -24

Divide by 12 to get z;

z = -2

Substitute z into x and y to get their values;

x = 3 + 2(-2)

x = 3 - 4

x = -1

y = -6 - 5(-2)

y = -6 + 10

y = 4

Now to check;

2x - y + 3z = -12

2(-1) - (4) + 3(-2) = -12

-2 - 4 - 6 = -12

-12 = -12

CORRECT!

Answer:

$11.66

Step-by-step explanation:

To find the average price, you need to find the total revenue, then divide that by how many tickets were sold.

2,000 * 15 = ? --> 30,000

*To find how how much money was made from the $15 tickets*

4,000 * 10 = ? --> 40,000

*To find how how much money was made from the $10 tickets*

30,000 + 40,000 = ? --> 70,000

*To find the total revenue*

2,000 + 4,000 = ? --> 6,000

*To find the total amount of tickets sold*

70,000 / 6,000 = ? --> 11.66666...

Average price per ticket

The average price per ticket is the ratio of the Cummulative earning and the total number of tickets sold, Hence, average price per ticket is $11.67

The Cummulative earning :

(4000 × $10) + (2000 × $15) = $70000

Total number of tickets sold

(2000 + 4000) = 6000 tickets

The average price per ticket :

$70000 ÷ 6000 = $11.67

Therefore, the average price per ticket is $11.67

Area of circle= πr² so, our radius would be 5in because the diameter is 10 in which makes our sum to be π×5²= 78.5 in

Circumference of circle= 2πr so, 2×5×π= 31.4 in

Answer:

Step-by-step explanation

1. area of a circle = πr²

2. circumference of a circle = 2πr

where diameter = 10 in.

                radius = 10 / 2 = 5 in

1. area of a circle = π(5)²

                            = 78.5 in²

2. circumference of a circle = 2πr

                                              = 2π(5)

                                             = 31.4 in
