Answer:

The value of x is 29.

Step-by-step explanation:

→ The angles arent congruent, they are supplementary.

→ Supplementary angles equals 180 degrees.

→ The equation looks look:

2x - 10 + 4x + 16 = 180

→ Let's solve the equation.

2x - 10 + 4x + 16 = 180 \\ 6x + 6 = 180 \\  \frac{  \:  \:  \:  \:  \: - 6 =  - 6}{ \frac{6x}{6} =  \frac{174}{6}  }  \\ x = 29

→ Therefore, the value of x is 29.

A rectangular swimming pool is twice as long as it is wide. A small concrete sidewalk surrounds the pool and is a constant 2 fee
Naddika [18.5K]

Answer:

The dimensions of the pool are:

Width: 8.944 feet

Length: 17.888 feet

Step-by-step explanation:

From Geometry, the area of a rectangle (A), measured in square feet, is determined by the following equations:

A = w\cdot l (1)

Where:

w - Width, measured in feet.

l - Length, measured in feet.

If we know that w = x, l = 2\cdot x and A = 160\,ft^{2}, then we get the following second order polynomial:

2\cdot x^{2}-160 = 0 (1)

And we solve the expression for x:

2\cdot x^{2} = 160

x^{2} = 80

x = \sqrt{80}\,ft

x \approx 8.944\,ft

Then, the dimensions of the pool are, respectively:

w \approx 8.944\,ft and l \approx 17.888\,ft

The number of trees in a rainforest decreases each month by 0.5%. The forest currently has 2.5 billion trees. Which expression r
Blababa [14]

Answer:

y=2.5*10^9(0.005^{12 0}) \\\\

Step-by-step explanation:

The above question is in the form of an exponential decay. The equation for an exponential decay is given by:

y=ab^x

where y and x are variables, b < 1, a is the initial value of y (that is the value of y when x = 0).

Let y represent the number of trees left and x represent the number of months. Given that there is currently 2.5 billion trees, therefore a = 2.5 * 10⁹, b = 0.5% = 0.005. The equations becomes:

y=2.5*10^9(0.005^x)\\\\After\ ten\ years(x=10*12\ months=120\ months):\\\\y=2.5*10^9(0.005^{12 0}) \\\\

What is the difference between the x-coordinates of B and C?
Brilliant_brown [7]

Answer:

Therefore, the point P (-3.5, 1.25) is the point 3/4 distance of A to B from A.

Step-by-step explanation:

The horizontal axis in the coordinate plane is called the x-axis. The vertical axis is called the y-axis. The point at which the two axes intersect is called the origin. ... In an ordered pair, such as (x, y), the first value is called the x-coordinate and the second value is the y-coordinate.
