If one bag of grass seed will cover 225 square feet, what is the minimum number of bags the haney family will need to cover thei

Veronika [31]

Answer:

9 bags

Step-by-step explanation:

First we will need to calculate the area of their entire backyard, which has a shape of trapezium.

So the formula for the area of a trapezium is $A=\frac{(a+b)*h}{2}$

a and b are the lenghts of the parallel sides and h is the height.

From the picture $a=10*5=50\\b=9*5=45\\h=8*5=40$

Then we plug into our formula

$A=\frac{(a+b)*h}{2} =\frac{(50+45)*40}{2} = 1200$ square feet

To get the number of bags required we just simply divide the aree of their entire yard by the space that 1 bag covers. We get:

$\frac{1900}{225} =8.444...$ bags

This is more than 8 bags so they will need 9 bags to cover their entire yard.

Miss Sandy is fencing in her rectangular backyard which is 3x^2 feet wide and 4xy + 5x^3 y^2 feet long. Find perimeter of yard H

hjlf

Given:

Width of rectangular backyard = $3x^2$ feet

Length of rectangular backyard = $4xy+5x^3y^2$ feet

To find:

The perimeter of yard.

Solution:

Formula or perimeter of a rectangle is

$Perimeter=2(length +width)$

Using this formula, the perimeter of the rectangular backyard is

$Perimeter=2(4xy+5x^3y^2+3x^2)$

$Perimeter=8xy+10x^3y^2+6x^2$

Therefore, the perimeter of the rectangular backyard is $8xy+10x^3y^2+6x^2$ feet. So, $8xy+10x^3y^2+6x^2$ feet fencing is needed.

Write an equation of the line that passes through a pair of points:

vredina [299]

Answer:

The equation of the line that passes through a pair of points

$y = \frac{-1}{8} ( x ) -\frac{11}{8}$

Step-by-step explanation:

Explanation:-

Given points are ( 5 ,-2) and ( 3,-1)

slope of the line

$m = \frac{y_{2} -y_{1} }{x_{2}-x_{1} } = \frac{-1-(-2)}{-3-(5)} = \frac{1}{-8}$

The equation of the line that passes through a pair of points

$y - y_{1} = m ( x - x_{1} )$

$y - (-2) = \frac{-1}{8} ( x - (5) )$

$y = \frac{-1}{8} ( x ) +\frac{5}{8} -2$

$y = \frac{-1}{8} ( x ) +\frac{5-16}{8}$

$y = \frac{-1}{8} ( x ) -\frac{11}{8}$
