Answer:
14 is 24
13 is 1.4
Step-by-step explanation:
answer 14:
First you need to add 10.1 and 1.9.
Second you need to multiply the answer you got by 4.
Last you need to divide the answer you got from the first two steps by 2.
Answer 13:
First you need to add 0.6 plus 7.4 and then multiply it by 2 because it is squared by 2.
Next you minus 14 from the answer you got from the first steps.
Answer:
126
Step-by-step explanation:
Total volume of sand = pi/3*(6^2)*(15) + pi*(6)^2*(30) = 1260*pi mm^3
So it will therefore take 1260*pi/10*pi = 126 seconds for all of the sand from the top hourglass to drip down to the bottom hourglass.
Shade the top side of the boundary line if you have the inequality symbols > or ≥. Shade the bottom side of the boundary line if you have the inequality symbols < or ≤.
=================•✠•================
H = 70ft.
P = 35ft.
B = ?
H^2 = P^2 + B^2
70×70 = (35×35) + B^2
B^2 = 4900-1225
B = √3675
B = 35√3 ft.
