We use the formula d = rt where d = distance, r = rate, t = time
Equation for Sam:
![d=( r_{1})(t)](https://tex.z-dn.net/?f=d%3D%28%20r_%7B1%7D%29%28t%29%20)
![d = 2t](https://tex.z-dn.net/?f=d%20%3D%202t)
Equation for Sam's father:
![d = (r_{2})(t - 0.33)](https://tex.z-dn.net/?f=d%20%3D%20%20%28r_%7B2%7D%29%28t%20-%200.33%29)
d = (12)(t - 0.33)
d = 12t - 4
Since Sam and his father have the same distance from their home to Sam's school, then
2t = 12t - 4
4 = 12t - 2t
4 = 10t
4/10 = t
t = 0.4 hrs or 24 mins
Sam travel 24 mins from home to school and his father travel 4 mins from home to school. Therefore, it was about 8:24 when Sam's father give the project to Sam.
We have that
<span>Cylinder A has a radius of 2 feet and a height of 4 feet
so
volume of the cylinder A=pi*r</span>²*h-----> pi*2²*4-----> 16*pi ft³
<span>Cylinder B also has a height of 4 feet, but the radius has been doubled
</span>h=4 ft
r=2*2---> 4 ft
so
volume of the cylinder B=pi*r²*h-----> pi*4²*4-----> 64*pi ft³
volume cylinder B/volume cylinder A=64*pi/(16*pi)----> 4
therefore
the answer is the option
<span>C) When the radius is doubled, the resulting volume is 4 times the original volume.</span>
Answer:
B
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180° , then
y + 10 + 2y + 50 = 180 , that is
3y + 60 = 180 ( subtract 60 from both sides )
3y = 120 ( divide both sides by 3 )
y = 40 → B
