​If \left| OA\right| =5∣OA∣=5 and \left| OA'\right| =7.5∣OA ′ ∣=7.5, what is the scale factor, rr, of this dilation?
Igoryamba

Answer:

The scale factor is 1.5

Step-by-step explanation:

Given

\left| OA\right| =5

\left| OA'\right| =7.5

Required

Determine the scale factor

The scale factor (k) is calculated using:

k = \frac{\left| OA'\right|}{\left| OA\right|}

Substitute values for OA and OA'

k = \frac{7.5}{5}

k = 1.5

<em>The scale factor is 1.5</em>

60 units needed, 14 units per case. What is the number of cases and the number of additional units?
Masja [62]

Answer:

5 cases

10 additional units

Step-by-step explanation:

Given that :

Total number of units needed = 60 units

Total number of units per case = 14

Hence, the total number of cases required will be :

Number of units needed / number of units per case

Number of cases required = 60 / 14 = 4.285 (this means that 5 cases are required as 4 cases won't be up to 60 units)

With 5 cases, we have exceeded the required units needed :

Additional units will be : (14 * 5) - 60

Additional units = 70 - 60 = 10 units
