Let
Vco------------------- >Volume cone
Vcy------------------ >Volume cylinder
r= 8mm
hco----------- > height of cone=18 mm
hcy------------ > height of cylinder =54-18=36 mm
then
Vco=π*r² *hco/3--------- > π*8² *18/3=π*384 mm³
Vcy=π*r² *hcy--------- > π*8² *36=π*2304 mm³
the total cubic millimeters of sand=Vco+Vcy=π*384+π*2304=π*2688
if 10π cubic millimeters --------------------- > 1 seg
π*2688--------------------------------- X
X=π*2688/10π=268.8 seg
the answer is 268.8 seg
Answer: Choice C) III onlyAs shown in the attached image, the altitudes are lines that are perpendicular to the sides of the triangle and they go through the opposite vertex. In the example shown, the orthocenter is the result of intersecting the altitudes. The
orthocenter is outside the obtuse triangle. It will never be on the triangle or on the inside of the triangle.
Answer:
Undefined or No solution
Step-by-step explanation:
Because this line is a straight, vertical line, it means that the slope is undefined, or no solution. Any time you see a straight line going up and down, this will be true. However, if you see a horizonal line, this will not be true.
Use the tangent ratio here: tan(18) = x / 4...4 tan(18) = x, and x = 1.30
Answer:
24 ( 12 -3x)
Step-by-step explanation:
(4x3 + 7x2 – 2) (2x2 – 3x + 8)
(12 + 14 - 2) (4 - 3x + 8)
(26-2) (12 - 3x)
24 (12 -3x)
