How do I solve this problem? You drive your car on a cold day (20^oF Outside) the engine overheats to about (220^oF). When you p

$ln(T- \frac{20}{200})=-0.11t \\ e^{ln(T- \frac{20}{200})}=e^{-0.11t} \\ T- \frac{20}{200} =e^{-0.11t} \\ T-0.1=e^{-0.11t} \\ T=e^{-0.11t}+0.1$
Then, now that we have solved for T, we can evaluate and solve for t=20 minutes.
$T=e^{-0.11t}+0.1 \\ T=e^{-0.11*20}+0.1 \\ T=e^{-2.2}+0.1 \\ T=0.11+0.1 \\ T=0.21$

Madison wants to make cookies for her little sisters .she is cutting a roll into pieces that are 1/2 inch if the roll is 13 inch

If you’re cutting it into half inch pieces, you’ll take the length of the roll and multiply it by 2, so 13•2=26

Cassidy's goal is to raise more than $75 for charity. She has already raised $6. Now she is selling cupcakes for $3 each to reac

hodyreva [135]

$75= Cassidy's goal
c= number of cupcakes
a= $6 already raised

EQUATION:
75<$3c + a
substitute $6 in for a

75< $3c + 6
subtract 6 from both sides

69<3c
divide both sides by 3

23<c

Cassidy needs to sell at least 23 cupcakes to reach her goal of $75.

Answer:

FALSE: Cassidy will need to sell any number of cupcakes greater than 12 to reach her goal.

TRUE: Cassidy will need to sell any number of cupcakes greater than 23 to reach her goal.

Hope this helps! :)
