an assembly line worker at Rob's Bicycle factory adds a seat to a bicycle at the rate of 2 seats in 11 minutes. Write a proporti
LuckyWell [14K]
Rate = 2 seats/11 minutes = 2/11  seats/min

Therefore the time required for s seats is
(m \, min) =  \frac{s \, seats}{ \frac{2}{11} \,  \frac{seats}{min} } =  \frac{11s}{2} \, min
That is,
m = (11s)/2 min

When s = 16, obtain
m =  \frac{11(16)}{2} = 88 \, min

When s = 19, obtain
m =  \frac{11(19)}{2} = 104.5 \, min

Answers:
m = \frac{11s}{2}
When s = 16, m = 88 min
When s = 19,  m = 104.5 min

Find the perimeter of a rectangle that is 2 and 1/2 yards by 4 and 1/2 yards
Travka [436]
The answer is 14. First, get both numbers and add them twice (2.5+2.5+4.5+4.5) or (2.5 * 2 + 4.5 * 2). Then you should get 2 numbers which are 9 and 5. Then it should be 14, which is the answer.

Write an equation for the line in slope-intercept form.​
atroni [7]

Answer:

y=3x+5

Step-by-step explanation:

Slope is rise/run. To find it, you first see how many units it goes up, followed by how many units it goes to the right. If you look at the point (-1, 2), it rises 3 tiles, and runs 1 tile until it hits the next whole number. Because your little formula is rise/run, it would be 3/1, or 3. And to get your y-intercept, it's just when it intersects the y-axis, which is at 5. So, your equation would be y=3x+5
