The Hot Summer Fair is coming to town! Admission to the fair costs $12.99 and each ride costs $1.75. You have $35 to spend at th

Anna [14]

As given,

Admission to the fair costs = $12.99

Cost of each ride = $1.75

Total money present = $35

Let the number of rides a person can take be x

Part A: The inequality that represents this situation is

35≤ 12.99 + x(1.75) where x represent the number of rides a person can take.

Part B:

Solving the equation we get,

35 = 12.99 + x(1.75)

1.75x = 35-12.99

1.75x = 22.01

x = $\frac{22.01}{1.75}$

x = 12.577

Hence a person can take upto 12 rides.

Segment CD is given with vertices C(a,b) and D(2a,b). Find the length of segment C'D', the image of segment CD after a dilation

artcher [175]

The dilation is a scale factor of 2, that is:

C'D' = 2(CD)

the length of CD is given by:
CD = √( (a - 2a)^2 + (b - b)^2 )

<span>CD = √(a^2) = a
</span>
hence the new segment is 2a long.

Factor-3/4 out of 3/2x-9/4y

S_A_V [24]

For this case we must factor $- \frac {3} {4}$ of the following expression:

$\frac {3} {2} x- \frac {9} {4}y$

By law of signs of multiplication it is fulfilled that:

$- * - = +\\- * + = -$

So we have to:

$- \frac {3} {4} * (- 2) = + \frac {6} {4} = + \frac {3} {2}\\- \frac {3} {4} * 3 = - \frac {9} {4}$

Thus, by factoring we have:

$- \frac {3} {4} (- 2x + 3y)$

Answer:

$- \frac {3} {4} (- 2x + 3y)$
