Answer:
Step-by-step explanation:
let x and y be the sides of the rectangle.
2(x+y)=44
x+y=44/2=22
y=22-x
1 tile=1 sq. ft.
120 tiles=120 sq.ft.
area=120 sq.ft.
xy=120
x(22-x)=120
22x-x²=120
x²-22x+120=0
x²-12x-10x+120=0
x(x-12)-10(x-12)=0
(x-12)(x-10)=0
x=12,10
if x=12
y=22-12=10
if x=10
y=22-10=12
floor dimensions are 12 ft ×10 ft
Answer:
f(x)=x+2 Passes through
x-y=2 DOES NOT pass through
Step-by-step explanation:
Method- plug in x and see if the y matches the points. (1,3) (7,9)
f(x)=x+2
f(1)=1+2=3
f(7)=7+2=9
Matches!
x-y=2
1-y=2 --> y=-1
Does not match
Answer:
U =35.5
Step-by-step explanation:
Since this is a right angle, we can use trig functions
tan theta = opp/ adj
tan U = 5/7
Take the inverse of each side
tan ^-1 tan U = tan ^-1 (5/7)
U = 35.53767779
Round to the nearest tenth
U =35.5
Answer:
A. 5:3
Step-by-step explanation:
There are 10 blue and 6 red so that's 10:6
