Answer:

a) The equation will you use to find the number of weeks x you will need to save is:

270 = 95.50 + 20x

b) The number of weeks x = 8.725 weeks

Step-by-step explanation:

Let:

The cost to join the Ski club = y

The number of weeks you will need to save = x

From the question, we have the following information:

The cost to join the Ski Club is $270. You pay a deposit of $95.50 and plan to save an additional $20 per week to pay for the cost.

The equation will you use to find the number of weeks x you will need to save is:

y = $95.50 + $20 × x

y = $270

Hence:

270 = 95.50 + 20x

Solving for x

270 = 95.50 + 20x

270 - 95.50 = 20x

174.5 = 20x

x = 174.5/20

x = 8.725 weeks

Hence, the number of weeks needed to save is 8.725 weeks

If each quadrilateral below is a parallelogram, find the missing measures.
prisoha [69]

Step-by-step explanation:

We will use parallelogram properties to answer our given problems.

(1) Since we know that opposite sides of parallelogram are congruent, therefore measure of side MN and side KN will be equal to the measure of their opposite sides.

LM=KN   and   KL=MN

Upon substituting our given values we will get,

45=KN   and   31=MN

Property: The opposite angles of parallelogram are congruent and consecutive angles are supplementary.

We have been given m\angle N=119^{o}, therefore m\angle L=119^{o}.

We will find measure of angle K by using supplementary angles.

m\angle N+m\angle M=180^{o}

119^{o}+m\angle M=180^{o}

m\angle M=(180-119)^{o}

m\angle M=61^{o}

By opposite angles of parallelogram m\angle K=61^{o}.

(2) Opposite sides of parallelogram are equal. Therefore, CF=DE and FE=CD.

Upon substituting our given values we will get,

CF=10  and FE=15.

Property: Diagonals of parallelogram bisect each other.

So CE will be 2 times CG and GD will be half the length of FD.

CE=2\times 7=14

GD=\frac{1}{2}\times 22=11

(3) Property: Opposite sides of parallelogram are congruent.

SR=PQ   and   QR=PS

Upon substituting our given values we will get,

SR=24   and   QR=19

Property: Diagonals of parallelogram bisect each other.

So SQ will be 2 times TQ and PT will be half the length of PR.

SQ=2\times 10=20

PT=\frac{1}{2}\times 42=21

Property: The opposite angles of parallelogram are congruent and consecutive angles are supplementary.

m\angle PQR=106^{o}

m\angle PQS=m\angle QSR  Alternate interior angles.

m\angle PQS=49^{o}

m\angle QRS=m\angle QPS Opposite angles of parallelogram.

m\angle PQR+m\angle QPS=180^{o}

106^{o}+m\angle QPS=180^{o}

m\angle QPS=180^{o}-106^{o}

m\angle QPS=74^{o}

Therefore, measure of angle QRS will 74 degrees.

m\angle PRS=m\angle QPR Alternate interior angles.

35^{o}=m\angle QPR

m\angle RPS=74^{o}-m\angle QPR

m\angle RPS=74^{o}-35^{o}

m\angle RPS=39^{o}

Now let us find measure of angle PSQ.

m\angle PSQ=m\angle PQR-m\angle QSR

m\angle PSQ=106^{o}-49^{o}

m\angle PSQ=57^{o}

The image is not clear, so I am unable to answer the last two problems.
