1.) The area of a room 6 1/5 meters long and 5 3/4 meters wide is <u>A</u><u> </u><u>=</u><u> </u><u>l</u><u> </u><u>x</u><u> </u><u>w</u><u>;</u><u> </u><u>l</u><u> </u><u>=</u><u> </u><u>6</u><u> </u><u>1</u><u>/</u><u>5</u><u> </u> or <u>3</u><u>1</u><u>/</u><u>5</u><u>;</u><u> </u><u>w</u><u> </u><u>=</u><u> </u><u>5</u><u> </u><u>3</u><u>/</u><u>4</u><u> </u> or <u>2</u><u>3</u><u>/</u><u>4</u>
Here's the Solution:
- A = l x w; l = 6 1/5 or 31/5; w = 5 3/4 or 23/4
- A = 31/5 m x 23/4m
- A = 713/20 m^2
- A = 35 13/20 m^2
HOPE THIS HELPS. GOODLUCK:)
I would say b but i’m not 100% sure
Answer: 135 degrees
Step-by-step explanation:
First you now that ABD+DBC=180 degrees
Subsitute so you get: (5x+10)+(2x-5)=180
Solve:
(5x+10)+(2x-5)=180
=> 7x+5=180
=> 7x=175
=> x= 25
Plug in 25 :
ABD= 5*25+10=135
And there is your answer
I believe f(5) is the number f equals hope that helped
