Answer:
D y = 9/x
Step-by-step explanation:
An inverse variation is of the form
xy = k where k is a constant
We can write this as
y = k/x
The only equation that is of this form is
D y = 9/x
Answer:
Obtuse triangle
Step-by-step explanation:
right triangle:
c² = a² + b²
10² = 3² + 5²
100 = 34 NO!
acute triangle:
c² < a² + b²
10² < 3² + 5²
100 < 34 NO!
Obtuse triangle:
c² > a² + b²
100 > 34 <u>YES</u>
Answer:
Step-by-step explanation:
The height is connected to the base of 16cm
Area = b * h
b = 16
h = 5
Area = b * h
Area = 16 cm * 5 cm
Area = 80 cm^2
Answer:
L=4.30cm
SA= 110.94cm^2
Step-by-step explanation:
Given data
Volume of box= 80 cm^3
We know that the volume of a box is given as
V= l^3
80=l^3
l= ∛80
l= 4.30cm
also the surface area of a box is given as
SA=2lw+2lh+2hw
SA= 2* 4.30* 4.30+2* 4.30* 4.30+ 2* 4.30* 4.30
SA= 36.98+36.98+36.98
SA= 110.94cm^2
