Step-by-step explanation:
Answer: the plain pencil costs 10 cents and the colored pencil costs 20 cents
1 year = 365 days.
It falls behind 1 minute per day:
365 days x 1 minute per day = 365 total minutes
1 hour = 60 minutes:
365 minutes / 60 minutes per hour = 6.083 hours = 6 hours and 5 minutes.
The area of triangle DEF is 2137.5 cm²
Solution:
Given data:
Area of ABC = 38 cm²
Scale factor = 7.5
To find the area of DEF:
<em>Area of dilated image = Area of original image × (scale factor)²</em>
Area of DEF = 38 × (7.5)²
= 2137.5 cm²
Area of DEF = 2137.5 cm²
The area of triangle DEF is 2137.5 cm²
