Answers

bryan: 32*4 = 128

132.48 - 128 = 4.48

4.48 /32 = 0.14 per golf ball

Eli: 52 *6 = 312

319.20 - 312 = 7.20

7.20 / 40 = 0.18 per golf ball

Damien: 28*5 = 140

144.08 - 140 = 4.08

4.08 / 24 = 0.17 per ball

if each small tile cost 15 pesos & each big tile should emmanuel use to economize in tilin his floor? explain why

Answers

It's not possible to answer this question without the other information in the middle,
which you skipped as you copied the question. That information tells us the size
of the big tiles, the size of the small tiles, and the size of the room.  That's how we
figure out how many tiles he needs, and once we know that, we can figure out how
much they cost.  (You also skipped the cost of the big tiles. We'll need that too.)

If the population of a particular country is growing at 1.6% compounded continuously, how long will it take the population to triple? The population will triple in ______ years if it is growing at 1.6% compounded continuously. (Round up to the nearest year.)

Answers

e ^(0.016t)=3 / * log _(e) \n log _(e) e^(0.016t)=log _(e) 3 \n 0.016t=log _(e) 3
0.016 t = 1.0986
t = 1.0986 : 0.016
t = 68.66 ≈ 69
The population will triple in 69years if it is growing at 1.6 % compounded continuously.

What formula tells the cost, in dollars, if chocolate chip cookies are $2.50/ dozen and lemon frosteds are $1.50/dozen? let c=number of dozens of chocolate chip cookies;L=number of dozens of lemon frosted; T= total charge

Answers

c= # of dozens chocolate chip cookies= $2.50/dozen

L= # of dozens of lemon frosted= $1.50/dozen

T= total charge

Multiply the number of dozens of chocolate chip cookies by the cost per dozen. Multiply the number of lemon frosted by the cost per dozen. Add those two together to equal the total cost.

T= ($2.50 * c) + ($1.50 * L)
T= $2.50c + $1.50L


ANSWER: T= $2.50c + $1.50L

Hope this helps! :)
