Answer:
2406.17 cm³
Step-by-step explanation:
The following data were obtained from the question:
Height (h) = 24.4 cm
Base length (L) = 17.2 cm
Volume (V) =?
Next, we shall determine the base area of the pyramid. This can be obtained as follow:
Base length (L) = 17.2 cm
Base area (B) =.?
B = L × L
B = 17.2 × 17.2
B = 295.84 cm²
Finally, we shall determine the volume of the pyramid. This can be obtained as follow:
Height (h) = 24.4 cm
Base area (B) = 295.84 cm²
Volume (V) =?
V = ⅓Bh
V = ⅓ × 295.84 × 24.4
V = 2406.17 cm³
Thus, we volume of the pyramid is 2406.17 cm³

Answer:
There were 10 children in the group
Step-by-step explanation:
Here, we want to know the number of children in the group;
Firstly , we were told that the group contains 16 people
Secondly, we are also told that 6 of the people there are adults
and there are only two ticket types ( adult and children)
So the number of children will be the total
number of people in the group- number of adults = 16-6 = 10
Hello :
the discriminat of each quadratic equation : ax²+bx+c=0 ....(a <span>≠ 0) is :
</span><span>Δ = b² -4ac
1 ) </span>Δ > 0 the equation has two reals solutions : x = (-b±√Δ)/2a
2 ) Δ = 0 : one solution : x = -b/2a
3 ) Δ <span>< 0 : no reals solutions
in this exercice : </span><span>2x ² - 3x - 1 = 0....a =2 b =-3 c =-1
calculate : </span>Δ ......................................
3n + 6 > = 12 (thats greater then or equal to)
