Answer:
The fraction of chores which Janie wants to earn enough money to buy a CD for $13.50 are 8.75~9 chores
Step-by-step explanation:
Given that Janie has $3. She earns $1.20 for each chore she does and can do fractions of chores. She wants to earn enough money to buy a CD for $13.50.
we have to find the fraction of chores Janie did to earn total of $13.50
Let the fraction of chores is x which Janie wants to earn enough money to buy a CD for $13.50.
Total money=$3+$1.20(fraction of chores)
$13.50=$3+$1.20(x)
$13.50-$3=$1.20(x)
x=8.75~9
Hence, the fraction of chores which Janie wants to earn enough money to buy a CD for $13.50 are 8.75~9 chores
Let's say that you're in your room and you find that the current temperature of 72 degrees is too cold, so slowly you increase the temperature of the room by two degrees.
We know that the explicit formula is
a^n=a^1+ (n-1)d
and so by substituting the given information in
a^n= 72 + (n-1)2
a^1=Initial temp
d= rate of change
by substitution a value of n (the term we are looking for) into this equation, you can then calculate the temperature that you just set the room too.
(-2,3) (3,0)
find slope
m= 0-3/(3+2) = -3/5
point slope is y-y1=m (x-x1)
point is (3,0) and m=-3/5
plug and chug
y-0=-3/5(x-3)
y=-3/5x+9/5
hope that helps
The figures cone Z and cylinder Y have the same volume.
Explanation:
The formula for volume of the cone Z is given by
The formula for volume of the cylinder Y is given by
Since, it is given that Cone Z has the same base area as cylinder Y, but its height is three times the height of cylinder Y.
Thus, substituting 
in the formula of volume of the cone Z, we get,
Simplifying, we have,
Hence, the volume of the cone Z = volume of the cylinder Y
Thus, the figures cone Z and cylinder Y have the same volume.
