WORTH 10 POINTS! 1)susan can type 4 pages of text in 10 minutes.Assuming she types at a constant rate,write the linear equation
that represents the situation
2)phil can build 3 birdhouses in 5 days.Assuming he builds birdhouses at a constant rate,write the linear equation that represents the situation.
3)train a can travel a distance of 500 miles in 8 hours.Assuming the train travels at a constant rate write a linear equation that represents the situation.
4)Natalie can paint 40 square feet in 9 minutes Assuming she paints at a constant rate write the linear equation that represents the situation.
5)bianca can run 5 miles in 41 minutes assuming she runs at a constant rate write the linear equation that represents the situation
6)Geoff can mow an entire lawn of 450 square ft in 30 minutes.Assuming he mows at a constant rate,write the linear equation that represents the situation.
(TRY TO ANSWER ALL OF THEM!! write a linear equation for all:)
1) pages per minute is the rate. the rate is the slope pages/minutes = .4 y=.4x or y=2/5(x) 2)birdhouses per day is the slope. = .6 y=.6x or y=3/5(x) 3) miles per hour is the slope. 500/8=62.5 y=62.5x 4) square feet per minute is the slope. 40/9 =4.444444444 y=4.4444444444x or y=40/9(x) 5)miles per minutes is the rate. 5/41 is the slope. y=5/41(x) 6) the rate is square feet per minute. 450/30=15 y=15x
TO find perimeter you add all sides. But to find the totaly of each side, you will divide. So a triangle has 3 sides, so you divide 45 by 3 to get the sides length of: 15 cm each ~hope this helped :)
