Answer:
<h2>
1200 jerseys each</h2>
Step-by-step explanation:
Step one:
we are told that the total available jerseys are 6000
this number of jerseys is to be divided among 5 schools.
hence we want to solve for the number of jerseys each school will collect from the store.
Step two:
A way to go about this is to divide the total available jerseys at the store, by the number of schools
that is 6000/5= 1200
This shows that each of the schools will collect 1200 jerseys from the store.
Answer:
720.85 cm3
Step-by-step explanation:
As the cylinders are similar, the ratio of their diameters is the same ratio of their heights, so we have that:
d1 /d2 = h1 / h2
If the volume of the larger cylinder is 9600 cm3, we can find its height:
V = pi*r^2 * h
9600 = pi * 32^2 * h
h = 9600 / (pi * 32^2) = 2.9842 cm
Now we find h2:
64 / 27 = 2.9842 / h2
h2 = 27 * 2.9842 / 64 = 1.259 cm
Finally, we can find the volume of the smaller cylinder:
V = pi * r^2 * h
V = pi * 13.5^2 * 1.259 = 720.85 cm3
Answer:
Step-by-step explanation:
Let us find the acceleration of box .
v² = u² + 2as
Putting the values
7² = 3² + 2 a x 14
a = 1.43 m /s²
If coefficient of friction be μ
force of friction = μ mg
= μ x 10 x 9.8
= 98μ
Net force pushing the box
= 85 - 98μ
Applying newton's second law
85 - 98μ = 10 x 1.43
98μ = 85 - 14.3
μ = .72
