During a sale at the grocery store mrs. reynolds bought 4.2 pounds of green beans for $5.25 is each of the following proportion to the sale price of green beans? select yes or no(a)6 pounds for $7.50 ) or (no)(b)3.4 pounds for $4.25 ) or (no)(c)3.5 pounds for $4.) or (no)\(d)5.8 pounds for $8.) or (no)(e) 2 pounds for $2.) or (no)

You can go at this in different ways. In the attached, we multiplied the number of pounds by the sale price per pound ($5.25/4.2). You can also figure the price per pound of each proposed purchase and compare with the sale price.

... sale price = $5.25/(4.2 lb) = $1.25/lb

(A) $7.60/(6 lb) = $1.25/lb (yes)

(B) $4.25/(3.4 lb) = $1.25/lb (yes)

(C) $4.20/(3.5 lb) = $1.20/lb (no)

(D) $8.70/(5.8 lb) = $1.50/lb (no)

(E) $2.50/(2 lb) = $1.25/lb (yes)

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.
