Jackie wants to start a garden in her backyard to grow vegetables. She built a frame that is 8 feet by 10 feet. She figures that she will need to add in top soil to be one foot deep. She goes to the local garden store to shop for soil and sees the following options for purchasing bags of soil : Brand A: 120 Ibs for $6 and Brand B : 200 Ibs for $8 Part A: what is the unit rate that Brand A is selling for? Ibs/dollar
Part B: which brand is offering better value? ( Brand A or Brand B) ?

18 units²

step-by-step explanation:

first let's find altitude bd using the distance formula

d = √((y₂ - y₁)² + (x₂ - x₁)²)

bd = √((0 - -3)² + (0 - 3)²)

bd = √18

given the placement of points a and c, we can denote that point d bisects segment ac.

we will call ac the base.

using the distance formula

ac = √((0 - 6)² + (-6 - 0)²)

ac = √72

knowing our base and our height, we can plug these into our triangle area formula

area = (b * h)/2

area = (√18 * √72) / 2

area = (√1296) / 2

area = 36 / 2

area = 18 units²

it goes right

it is impossible.

arc length = 6.63311 ft.

step-by-step explanation:

the formula the arc measure is:

arc length s=2πr(c)/360

where:

c   is the central angle of the arc in degrees

r   is the radius of the arc

π   is pi, approximately 3.142

using the above formula we get

s =

thus we find that arc length of an arc for a circle of radius 20 feet and central angle 19 degrees is

6.63311 feet
