4 times 7 is 28
3 times 3 is 9
28-9=19
Answer:
18.7 inches
Step-by-step explanation:
The question says that the height of a square pyramid is one half the length of each side. the volume of the pyramid is 972in³ and we are now asked to find the height of the pyramid
----The volume of a square pyramid is
V = A(h/3)
And since the height is one half(3/2) of the base
Let's assume that the base is y inch
Height = 3/2 × y,
Base area = y × y = y²
Volume of the pyramid = 3/2 × y × y² ÷ 3 = 972
Y/2 × y² = 972
Y³ = 1944
Y = ³√1944
Y = 12.48
Since the lenghy of the base is 12.48 in
And the height us 3/2 of y,
H = 3/2 × 12.48
Height is 18.7 inches
Answer:
E) 48
Step-by-step explanation:
uhh I honestly have no idea hot to explain it but lemme try
so if you draw a line where the hypotenuse and the 4 in meet, you make a rectangle and a triangle then you can use Pythagorean Theorem to find the length of the unknown side and add them all together
Answer: -4.8
Step-by-step explanation:
Factor: -2
-0.3, 0.6, -1.2, 2.4,
-0.3*(-2) = 0.6
0.6*(-2) = -1.2
-1.2*(-2) = 2.4
2.4*(-2) = -4.8
Answer:
8
