Volume of Pyramid is given by 1/3 base area x height
From the figure we see the base have equal side x so it is a square .Are of
Base = area of square.
Area of base = area of square = x .x = x2
Volume of Pyramid = 1/3 . base area .height
Volume of Pyramid = 972 cubic inches given.
Height of Pyramid= ½ x inches .
Substituting the values of volume ,height and base area we have:
972=1/3 .x2.1/2 x.
972=1/6 x3
Multiplying both sides by 6 we have:
5832=x3
Taking cuberoot of both sides.
X=18in
Length of the side of base is x= 18in each height is ½ x = ½ .18= 9 in
Because two sides are the same length, it will be an isosceles triangle.
B y=70x+100 D y=70x
Speed is the rate of change of distance over time.
The equation that shows the relationship is
The given parameters are:
Distance = 100 yards
Speed = 70 miles per hour
Speed is calculated as:
So, we have:
Multiply both sides by x
Hence, the equation that shows the relationship is

Answer with Step-by-step explanation:
The cheetah was clocked running 70 miles per hour.
i.e. in 1 hour cheetah covered 70 miles
in 2 hours cheetah covered 140 miles
in 3 hours cheetah covered 210 miles
in general, in n hour cheetah covered 70n miles
If y denote the distance covered
and x denotes the time cheetah runs
Then, y=70x
Hence, the equation which shows the relationship between the distance, y, and time, x, the cheetah runs is:
D y=70x
