Answer:
The winner of biggest loser would be Antone.
Step-by-step explanation:
the weight lost by each individual would be = ( initial weight of the individual)-(final weight of the individual)
therefore weight lost by Courtney will be 270-176=94.
weight lost by Patrick will be 387-296= 91.
weight lost by Antone will be = 447-298 = 149.
therefore The winner of biggest loser would be Antone.
Answer:

Step-by-step explanation:
1. Convert both mixed numbers into improper fractions:

2. Multiply both sides by 4:
4 ·
· 4
15x = 5
3. Isolate x:
x = 1/3
hope this helps!
Answer:
East and west side= 5 foot
South and north side = 10 foot
Area = 50 foot^2
Step-by-step explanation:
We know that:
East and west fencing cost= $4 per foot
South and north fencing cost $2 per foot
So, we can consider:
x= south and north fencing
y= east and west fencing
Then we create an equation representing the case:
Total cost = (south+north)*$2 + (east+west)*$4
80 =(x+x)*2 + (y+y)*4
80 =(2x)*2 + (2y)*4
80 =4x + 8y
80 =4*(x+2y)
80/4 =x+2y
20 = x+2y
x= 20-2y
We can calculate the area as width * length:
Area = length * width
Area= x * y
Area= (20 - 2y) * y
area= 20y - 2y^2
Next step is to find the "y" value for the maximum area so you can derivate and equal to 0 to find maximums:
d(20y - 2y^2)/dy = 20 - 2*2y = 20 - 4y
20 - 4y = 0
20 = 4y
y = 20/4
y = 5
If y = 5, then:
x = 20 - 2y
x = 20 - 2*5
x = 20 - 10
x = 10
Answer:
x= 6
Step-by-step explanation:
you can do 6 squared, which is also equal to 6 x 6
