How many square feet of carpeting are needed to carpet a 12-foot by 12-foot room

1 answer:

7 0

Square feet refers to area, so you would need to find the area of the room.

Area of a rectangle = length × width
Length = 12 ft
Width = 12 ft
A = l×w
= 12 ft × 12 ft
= 144 sq. ft

Thus, you would need 144 square feet of carpeting.

Q: What is the least they could weigh together?

A: 0.62 kg

=================================================

Work Shown:

x = weight of first ball

y = weight of second ball

each ball has a weight range of 0.31 kg to 0.37 kg, so,

$0.31 \le x \le 0.37$

$0.31 \le y \le 0.37$

add straight down to get

$0.31+0.31 \le x+y \le 0.37+0.37$

which simplifies to

$0.62 \le x+y \le 0.74$

the two soccer balls have a weight range of 0.62 to 0.74, inclusive of both endpoints.

--------

Without using algebra, you basically just add the smallest the two weights could be (0.31) to itself to get 0.31+0.31 = 0.62 which represents the smallest the two weights combined can be. The same happens with the largest weight of 0.37 to get 0.37+0.37 = 0.74 as the max weight of both objects together.

For the given quadratic equation convert into vertex form, find the vertex, and find the value for x = 6. Show your work. y = -2

telo118 [61]

Y= -2(x²-x)+2= -2(x-1/2)²+2+1/2= -2(x-1/2)²+5/2
x=6, y= -2(11/2)²+5/2= -121/2+5/2= -58

I hope this helps
