Answer:
37.6
Step-by-step explanation:
x² = a² + b² - 2ab cos 140°
x² = 20² + 20² - 2(20)(20)(-0.766)
x² = 400 + 400 - 800(-0,766)
x² = 800 - (-612.835)
x² = 800 + 612.835
x² = 1412.835
x =√1412.835 = 37.6
Answer:subtraction property of equality
Step-by-step explanation:
small has 3 combos
medium has 3 combos
large has 3 combos
to figure out how many combos you can make you do 3*3*3 which equals 27
Answer:
the surface area of the cylinder in terms of pi=2πrh+2πr² =2×π×7×18+2π×7²=350πwhere
r=radius=7cm
h=height of the cylinder.=18cm
a.350πcm² is your answer
1.y varies directly with x
2.substitute the value of x and y in the equation below
y=kx
where k is the constant term
60=20k
k=60\20
k=30
:y=30x.....is the law
To find y when x is 12
You reinstate the law which is y=30x
Then substitutes the value of x to determine y
y=30*12
y=36.
