You buy two types of fish at the local market. you need 1.5 pounds of tilapia and
1 pound of cod. tilapia costs $3.88 per pound and cod costs $3.53 per pound. how much is your fish purchase ?

answer:

$9.35

step-by-step explanation:

tilapia: 1.5 * $3.88 = $5.82

cod: 1 * 3.53 = $3.53

$3.53 + $5.82 = $9.35

answer:

9.35

step-by-step explanation:

3.88/2= 1.94 for every half pound of tilapia

1.94+3.88+3.53=9.35

answer:

perimeter of δabc = 19.2 ft

step-by-step explanation:

given that de, df and ef are midsegments of δabc and de=3.2 feet,

ef=4 feet, and df=2.4 feet

the value of the midsegment is half value of the corresponding side of the triangle, which means:

ef = 1/2 ab => ab = 2 · ef = 2 · 4 = 8 ft

ab = 8 ft

de = 1/2 bc => bc = 2 · de = 2 · 3.2 = 6.4 ft

bc = 6.4 ft

df = 1/2 ac => ac = 2· 2.4 = 4.8 ft

ac = 4.8 ft

perimeter of the δabc is:

p = ab + bc + ac = 8 + 6.4 + 4.8 = 19.2 ft

p = 19.2 ft
