Answer:
Cost of 12 pencils = 37 4/5 = 189/5
Cost of 1 pencil = 189/5 ÷ 12
= 189/5 x 1/12 = 189/60 = 63/20 = 3 3/20
So required answer is 3 3/20

Answer:
km
Step-by-step explanation:
The submarine's path from its base forms a right triangle when its final position is "connected" to the base. We know that the right triangle has legs of
km and
km, and we need to find the length of its hypotenuse. To do so, we can use the Pythagorean Theorem, which states that in a right triangle,
, where
and
are the lengths of the triangle's legs and
is the length of the triangle's hypotenuse. In this case, we know what
and
are, and we need to solve for c, so after substituting the given values of
and
into
to solve for c, we get:

(Substitute
and
into the equation)
(Evaluate the squares on the LHS)
(Simplify the LHS)
(Symmetric Property of Equality)
(Take the square root of both sides of the equation)
(Simplify)
is an extraneous solution because you can't have negative distance, if that makes sense, so therefore, the submarine is approximately
km away from its base. Hope this helps!
Answer:
Step-by-step explanation:
They're asking for the initial fuel, which is how much it had when the distance was 0. so 500, your y-intercept
Answer:
=
with T₁ = 5000
Step-by-step explanation:
There is a common ratio r between consecutive terms in the sequence, that is
r =
=
=
= 
This indicates the sequence is geometric with recursive rule
= r 
Here tr =
, thus
=
, T₁ = 5000
Answer:
riding a bicycle to and from school each day
Step-by-step explanation:
As this involves the constant application of force from the leg muscles, this will help to build a stronger body.
