Kids bought a package with 2 9/ 16 lb of ground meat to make hamburgers he was he has 2/5 pound of ground meat left about how ma

poizon [28]

Answer:

The quantity of ground meat he use for hamburgers is 2 $\frac{13}{80}$ pounds

Step-by-step explanation:

Given as :

The total quantity of ground meat bought to make hamburgers = 2 $\frac{9}{16}$

Or, The total quantity of ground meat bought to make hamburgers = $\frac{41}{16}$ pound

The quantity of ground meat left after use = $\frac{2}{5}$ pound

Now, let The quantity of ground meat used for hamburgers = x pound

So, x = The total quantity of ground meat bought - The quantity of ground meat left

Or, x = $\frac{41}{16}$ pound - $\frac{2}{5}$ pound

Or, x = $\frac{205-32}{80}$ pound

I.e x = $\frac{173}{80}$

∴ x = 2 $\frac{13}{80}$ pounds

Hence The quantity of ground meat he use for hamburgers is 2 $\frac{13}{80}$ pounds . Answer

inna [77]

Answer:

Ed Moura invest $64000 in certificates of deposit paying 3%

Step-by-step explanation:

Ed Moura has $32000 invested in stocks paying 6%.

Additional money in certificates of deposit paying 3% =x

so that the average return on the two investments is 4%.

32000*6% +3%*x = 4%(32000+x)

32000*0.06 +0.03*x = 0.04(32000+ x)

1920 + 0.03x = 1280 +0 .04x

1920 - 1280 = 0.04x - 0.03x

0.01x = 640

x = 64000

x = $64000

x= $64000 in certificates of deposit paying 3%
