A rectangular patio has a length of 12 1/2 feet and an area of 108 1/8 square feet what is the width of the patio

Ivenika [448]

Length of the rectangular patio = $12\frac{1}{2}=\frac{25}{2}$

Let the width of the patio be = x

Area of the patio is given as = $108\frac{1}{8}=\frac{865}{8}$

As the area of a rectangle is = length*width, so

$\frac{865}{8}=(\frac{25}{2})x$

$\frac{865}{8}*\frac{2}{25}=x$

x= $\frac{1730}{200}$ = $\frac{173}{20}$

x = $8\frac{13}{20}$

Hence, width of the patio is $8\frac{13}{20}$ feet.

An arch in the shape of the upper half of an ellipse is used to support a bridge that is to span a river 20 meters wide. The hei

MatroZZZ [7]

Title:

<h2>Check the explanation.</h2>

Step-by-step explanation:

The standard form of an ellipse is $\frac{x^{2} }{a^{2} } + \frac{y^{2} }{b^{2} } = 1$ .

The span of the river is 20 meters. As per the given condition, y-axis will pass through the middle point of the river. That is why, the value of a will be $\frac{20}{2} = 10$ .

Since the height of the arc is 6, the value of b is 6.

The equation of the arc will become $\frac{x^2}{{10}^2} + \frac{y^2}{6^2} = 1$ .

A direct variation function contains the points (-9, -3) and (-12,4). Which equation represents the function?

Triss [41]

Answer:

$y = -\frac{7x}{3} - 24$

Step-by-step explanation:

We can model this function using the equation of a line:

$y = ax + b$

Where a is the slope of the line and b is the y-intercept.

To find the values of a and b, we can use the two points given:

(-9, -3):

$-3 = a * (-9) + b$

$-9a + b = -3$

(-12, 4):

$4 = a * (-12) + b$

$-12a + b = 4$

If we subtract the second equation from the first one, we have:

$-12a + b - (-9a + b) = 4 - (-3)$

$-12a + 9a = 4 + 3$

$-3a = 7$

$a = -7/3$

Then, finding the value of b, we have:

$-12a + b = 4$

$28 + b = 4$

$b = -24$

So the equation is:

$y = -\frac{7x}{3} - 24$
