Answer:
123= 60
Step-by-step explanation:
85=> ( 41*2)+3
113=> (55 x 2)+3
49=> ( 23 x 2) +3
123=> ( 60*2)+3
Answer:
y = (-1/4)x + 9/4
Step-by-step explanation:
2y = 8x - 6
So, y = 4x - 3 (Slope = 4)
Slope of perpendicular line = -1/4
Equation of line: y-3 = (-1/4)(x-(-3))
y-3 = (-1/4)x - 3/4
y = (-1/4)x + 9/4
Answer:
<em>The shortest side of the fence can have a maximum length of 80 feet</em>
Step-by-step explanation:
<u>Inequalities</u>
To solve the problem, we use the following variables:
x=length of the longer side
y=length of the sorter side
The perimeter of a rectangle is calculated as:
P = 2x + 2y
The perimeter of the fence must be no larger than 500 feet. This condition can be written as:
The second condition states the longer side of the fence must be 10 feet more than twice the length of the shorter side.
This can be expressed as:
x = 10 + 2y
Substituting into the inequality:
This is the inequality needed to determine the maximum length of the shorter side of the fence.
Operating:
Simplifying:
Subtracting 20:
Solving:
The shortest side of the fence can have a maximum length of 80 feet
Answer:
It appears that the books have a scale factor for each one, meaning that <u>the 5th book would be 1200g</u>.
To check this regarding the average weight, add the weight of all 5 books together and divide by 5.
(400 + 600 + 800 + 1000 + 1200) / 5 = 800
I just calculated it and it's 13 ..
