Answer:

42 points

Step-by-step explanation:

If Brooke scored 27 points, 12 less than that would be what Cienna scored. To find this, you would do 27 - 12. This is equal to 15, so Cienna scored 15 points.

To find how much they scored together, you would add both their scores. Brooke scored 27 and Cienna scored 15, so 27 + 15 = 42. Therefore, they scored 42 points together.

For the given measures of angles of heptagon, the value of x is equal to 27° .

As given in the question,

Sum of all the interior angles of the heptagon is equal to 900.

Given measure of all the angles of the heptagon is given by :

135°+( 5x - 4 )° +( 7x - 64 )° + 120° +( 6x - 8 )° +( 4x + 15 )° + ( 3x + 31 )°= 900°

Arrange all the like terms of the given expression together we get,

⇒ ( 5x + 7x + 6x + 4x + 3x )° + ( 135 - 4 - 64 + 120 - 8 + 15 + 31 )°  = 900°

⇒ 25x° + 225° = 900°

⇒ 25x° = 900° -225°

⇒ 25x° = 675°

⇒ x = 27°

Therefore,  for the given measures of angles of heptagon, the value of x is equal to 27° .

Answer:

x=10

Step-by-step explanation::

We can use Triangle angle bisector theorem and proportions to solve this problem.  We put the small triangle side over the large triangle side

8           x+4

------ = ------------

12          2x+1

Using cross products

8(2x+1) = 12(x+4)

16x+8 =12x+48

Subtract 12x from each side

16x-12x +8 = 12x-12x+48

4x+8 = 48

Subtract 8 from each side

4x+8-8 = 48-8

4x = 40

Divide by 4

4x/4 = 40/4

x = 10

The given equation solved for u is u = 7 or u = -7

From the question, we are to solve the given equation.

The given equation is

u^6 − 49 u^4 = 0

First, we will write the equation properly

The given equation written properly is

u⁶ - 49u⁴ = 0

Now,

To solve the equation, we will determine the value(s) of the variable. The variable in the given equation is u.

Thus,

We will solve for u

u⁶ - 49u⁴ = 0

Add 49u⁴ to both sides of the equation

u⁶ = 49u⁴

Divide both sides by u⁴

u⁶/u⁴ = 49u⁴/u⁴

u² = 49

Then,

u²- 49 = 0

u² - 7² = 0

Factorize by applying the rule for difference of two squares

(u + 7)(u - 7) = 0

Then,

u + 7 = 0 OR u - 7 = 0

u = -7 OR u = 7

Hence, the value of u is -7 OR 7

The derivative of given function is H’(t) = 3 – 2/t3

A derivative is a two-party contract whose value/price is derived from an underlying asset. Futures, options, forwards, and swaps are the most prevalent types

Given that H(t)= t+ 1/t^2+2t+2

We must calculate the derivative

H(t)= t+ 1/t^2+2t+2

H(t) = 3t + 1/t^2 + 2

H’(t) = d/dt(3t + 1/t^2 + 2)

H’(t) = d/dt(3t) + d/dt (1/t^2) + d/dt ( 2)

H’(t) = 3xd/dt(t) + d/dt (1/t^2) + d/dt ( 2)

H’(t) = 3xd/dt(t) + d/dt (t-2) + d/dt ( 2)

H’(t) = 3 – 2t-3

H’(t) = 3 – 2/t3

The slope of the line is -3 and the equation of the line formed by the points is y + 3x = 6.

From the table we can see that the line passes through the points:

(-6,6) ,(5,-3) ,(4,0) and (3,3) .

Let us consider any two points on the line (4,0) and (3,3) .

We know that the slope of the line can be found by using the intercept formula

Hence slope = (3-0) / (3-4) = 3/ -1 = -3

Now the equation of the line is :

y - 3 = -3(x-3)

or, y - 3 = -3x +9

or, y + 3x = 6

The letter m is frequently used to represent the slope of an object that resembles a line in the plane that contains the x and y axes. The slope is defined as the difference in two independent locations along the line expressed in y coordinate less by the equivalent difference in x coordinate.

Therefore slope of the line is -3.

The number of adults is 200 and the number of children that entered the carnival after it was opened is 240.

Let a represent the number of adult tickets sold

Let c represent the number of children tickets sold

4a + 2c = 1380

Hence,

a + c = 440

Solving  for c

4 (440-c) +2c = 1280

1760-4c +2c = 1280

-4c+2c = -480

-2c=-480

Divide both side by -2c

c = -480/-2

c = 240 (children tickets)
