Step-by-step explanation:
The question is incomplete..
The given parameters can only solve for the number of hours the battery can last if at full capacity.
Given
25% = 4.5 hours
Required
Determine the brand
First, we need to determine the full capacity (100%)
So, we have:
25% = 4.5 hours
100% = x
Cross Multiply
25% * x = 100% * 4.5 hours
Divide both sides by 25%
x = 4 * 4.5 hours
x = 18 hours
Hence, the battery at full capacity is 18 hours.
So, to answer the question, you need to check the given list of brands.
The brand closest to 18 hours answers the question
D, Because 7/15 + 9/15 is 16/15 + 4/15 =20/15 which equals 1 5/15 which turns into 1 1/3
A, 1/21 + 2/21 = 3/21 and that equals 1/7
C, 3/14+3/12 turns into 3/14+5/14= 10/14 - 8/14= 2/14=1/7
Answer:
(3, 3) × 13 = (39, 39)
(0, 3) × 13 = (0, 39)
(6, -6) × 13 = (78, -78)
(9, 6) × 13 = (117, 78)
Step-by-step explanation:
Because the center of dilation is at (0, 0), or the origin, we can just multiply the x and y values of each point by the scale factor of 13.
(3, 3) × 13 = (39, 39)
(0, 3) × 13 = (0, 39)
(6, -6) × 13 = (78, -78)
(9, 6) × 13 = (117, 78)
