1.6 divided by x =4
we can exchange the 4 and the x
1.6 divided by 4 =x
.4 =x
The thing that is required for a <span>proportional relationship would be that no matter what the order of the relationship is, it should be that if the function of x increases then x would increases as well or vice versa. Hope this helps. Have a nice day. Feel free to ask more questions. </span>
Answer:
<h2>x = 60°, y = 50°</h2>
Step-by-step explanation:
We know: the angles measures in a triangle add up to 180°.
<em>(look at the picture)</em>
z + 50 + 60 = 180
z + 110 = 180 <em>subtract 110 from both sides</em>
z = 70°
x + 50 + 70 = 180
x + 120 = 180 <em>subtract 120 from both sides</em>
x = 60°
Angles x, y and z are on one side of a straight line. Therefore they add to 180°.
x + y + z = 180
60 + y + 70 = 180
y + 130 = 180 <em>subtract 130 from both sides</em>
y = 50°

Answer:
V = 0.52 cm³
Step-by-step explanation:
radius r = 0.5 cm
volume V = 0.523333333 cm³
surface area A = 3.14 cm²
circumference C = 3.14 cm
In Terms of Pi π
volume V = 0.166666667 π cm³
surface area A = 1 π cm2
circumference C = 1 π cm
Agenda: r = radius
V = volume
A = surface area
C = circumference
π = pi = 3.1415926535898
Formulas:
Sphere Formulas in terms of radius r:
Volume of a sphere:
V = (4/3)πr³
Circumference of a sphere:
C = 2πr
Surface area of a sphere:
A = 4πr²
