Let x be the number of months the calf grows.
1000 = 65x + 90
65x=910
x= 14
Percent change=(change/original) tiimes 100
change= |original-new|
so
12 to 36
|12-36|=|-24|=24
so
pcercent change=100 times (24/12)=100 times 2=200%
50 to 35
|50-35|=|15|=15
percent change=100 times (15/50)=100 times 100 times 0.30=30%
10 to 24
|10-24|=|-14|=14
percent change=100 times (14/10)=100 times 1.4=140%
16 to 44.2
|16-44.2|=|-28.2|=28.2
percent change=100 times (28.2/16)= 100 times 1.7625=176.25%
answers are
-12 inches to 36 inches: 200%
-50 punds to 35 pounds: 30%
-10 gallons to 24 gallons: 140%
-16 centimeters to 44.2 centimeters: 176.25%
Answer:Answer:a) Area=f(x)= 24x-x^2
b) f(x) ranges from 0 to 144
c) Area max = 144 ft^2

Answer:
x=2 and y=−6
sorry this is pretty long, I did not know if you needed the steps or not
Step-by-step explanation:
−2y−10=x;−10x−y=−14
Solve−2y−10=x for x
−2y−10=x
−2y−10+−x=x+−x
−x−2y−10=0
−x−2y−10+2y=0+2y
−x−10=2y
−x−10+10=2y+10
−x=2y+10
-x/-1=2y+10/-1
x=−2y−10
Substitute−2y−10 for x in−10x−y=−14
−10x−y=−14
−10(−2y−10)−y=−14
19y+100=−14
19y+100+−100=−14+−100
19y=−114
19y/19=-114/19
y=-6
Substitute−6 for y in x=−2y−10
x=−2y−10
x=(−2)(−6)−10
x= 2
x=2 and y=−6
Answer:
Michael worked 4 hours and Landon worked 10 hours.
Step-by-step explanation:
Michael can iron 40 shirts each hour, so in xx hours he can iron 40x40x shirts. Landon can iron 20 shirts each hour, so in yy hours he can iron 20y20y shirts. The total number of shirts ironed 40x+20y equals 360:
40x+20y=360
40x+20y=360
Since Michael and Landon worked a combined 14 hours, we know x+yx+y must equal 14.
x+y=14
Write System of Equations:
40x+20y= 360
x+y=14
Solve for y in each equation:
40x+20y = 360 x+y = 14 20y = -40x+360
=
y = -2x+18
