During his trip, sara knits a bright, oranges scarf at the rate of 469 mm every hour. if her trip last 8 days and if sara sleeps only 5 hours a day, how much of the scraf will she knitted by the end of the trip?

For this case, the first thing we must do is define variables.

We have then:

x: number of hours

y: Amount of scarf that Sara knits

We then have the following equation that models the problem:

The number of hours during the 8 days is given by:

Substituting the value of x in the ada equation we have:

she will knitted by the end of the trip about 52528mm of scarf

15.5

step-by-step explanation:

5

∑

n = 1

substitute n = 1, 2, 3, 4, 5 and sum the terms

= + + + 2² + 2³

= 0.5 + 1 + 2 + 4 + 8

= 15.5

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet
