Answer:
$22.50
Step-by-step explanation:
I think the unit of the sand sold is actually in cubic inches and not square inches.
V = L*B*H
V = 2.5 * 3 * 6
V = 45 in³
If 1 in³ = $0.50
45 = x
x = 45 * $0.50
x = $22.50

Answer:
A = 1,307 cm^2
Step-by-step explanation:
Formula of Surface Area of a Rectangle:
A = 2 (lw + lh + wh)
length*width = (20)(23) = 460
length*height = (23)(4.5) = 103.5
width*height = (20)(4.5) = 90
A = 2 (460 + 103.5 + 90)
A = 2(653.5)
A = 1,307 cm^2
Answer:
Step-by-step explanation:
as (c + 9)(c - 9) = c² - 81
and (c - 9)(c + 6) = c² - 3c - 54
<u> 8(c + 6) </u> = <u> 8c + 48 </u>
(c² - 81)(c + 6) (c - 9)(c + 9)(c + 6)
<u> 10c(c + 9) </u> = <u> 10c² + 90c </u>
(c² - 3c - 54)(c + 9) (c - 9)(c + 9)(c + 6)
bearing in mind that, arcs get their angle measurement from the central angle they're in. Thus, the measure of that central angle, is the same measure in degrees of that arcDF.
