Answer:
1800 watt hours
Step-by-step explanation:
6300 watt hours in 3 days and 12 hours
3 x 24 = 72 3 days worthof hours
72 + 12 = 84 total hours
6300/84 = 75 watt hours per hour
75 x 24 = 1800 watt hours per day
Answer:
A. y+8=2(x-4)
Step-by-step explanation:
A line perpendicular to y=-1/2x+11 would have slope +2, which is the negative reciprocal of -1/2.
Starting with the slope-intercept form of the equation of a straight line, find the y-intercept based upon this new line's passing through (4, -8):
y = mx + b becomes -8 = 2(4) + b. Then b = -16, and the desired new line is
y = 2x - 16.
Eliminate answer choices B and C, because 1/2 is not the correct slope.
Choice A is correct. Note that the result of subbing 4 for x and -8 for y into A: y + 8 = 2(x - 4) is a true equation: -8 + 8 = 2(4 - 4)
Also note that y + 8 = 2(x - 4) can be written in slope-intercept form:
y = -8 + 2x - 8, or y = 2x - 16 (same as obtained earlier)
Answer:
B) 2/3=x/4
Step-by-step explanation:
Since the figures are similar, we can use ratios to solve

Answer:
Length of string used by Claire = 7 / 3 feet
Step-by-step explanation:
Given:
Length of string Claire in starts = 
feet
Length of string Claire in end = 
feet
Find:
Length of string used by Claire
Computation:
Length of string Claire in starts = feet = 25 / 6 feet
Length of string Claire in end = feet = 11 / 6 feet
Length of string used by Claire = Length of string Claire in starts - Length of string Claire in end
Length of string used by Claire = [25 / 6] - [11 / 6]
BY taking LCM
Length of string used by Claire = [25 - 11] / 6
Length of string used by Claire = 14 / 6
Length of string used by Claire = 7 / 3 feet
Answer:
35 and 24
Step-by-step explanation:
35 + 24 = 59
35 - 24 = 11
