The local video store charges a monthly membership fee of $5 and $2.25 per video, write this as a algebraic expression

Answers

Answer:

$5 + ($2.25x)

Step-by-step explanation:

The local video store charges a monthly membership fee = $5

and per video charges = $2.25

Let the videos taken = x

So, the algebraic expression to calculate the total monthly charges will be

$5 + ($2.25x)
$5+ ($2.25x)=y

I believe this is correct.

Find the volume of a sphere with a circumference of 48 pi ft. Write your answer in terms of pi .

Answers

Answer:

18,432 pi cubic ft

Step-by-step explanation:

This problem can be solved using formula to find circumference and volume of sphere

for any sphere with radius r

circumference of sphere is 2* pi * r

volume of sphere is found by using formula 4/3*(pi*r^2)

Given circumference of sphere is 48 pi ft

therefore

2* pi * r = 48 pi ft

r = 48 pi ft/ 2* pi = 24 ft

substituting the value of r is formula of volume of sphere we have

volume of sphere is = 4/3*(pi*24^3) = 18,432 pi cubic ft

If triangle MNO is congruent to triangle PQR , which of the following can you NOT conclude as being true.. a- line MN is congruent to like PRb- angle M is congruent to angle P
c- line NO is congruent to line QR
d- angle N is congruent to angle Q

Answers

The correct answer is:

A) line MN is congruent to line PR.

Explanation:

We are told that MNO is congruent to PQR. Using this congruence statement, corresponding parts of the triangles are congruent. This means that line MN would be congruent to line PQ, not line PR.

Answer:

a- line MN is congruent to line PR.

Step-by-step explanation:

It is given Δ MNO ≅PQR.

In congruent triangles corresponding sides and corresponding angles are same .

Hence

< M≅<P ,

Line NO= Line QR.

<N≅<Q.

Line MN≅Line PQ.

Among the given options options b,c,d are correct except option a.

We can  NOT conclude as being true.. a- line MN is congruent to line PR
