|a| = a for a ≥ 0

examples

|2| = 2, |4| = 4, |234| = 234, |1/2| = 1/2, |0| = 0

|a| = -a for a < 0

examples

|-4| = -(-4) = 4, |-6| = -(-6), |-123| = 123, |-4/5| = 4/5

|5 - 15| = | - 10| = 10

0 × |-6| = 0

Answer:

10 and 0.

Step-by-step explanation:

The absolute value of a number is |x|= x if x≥0 or |x|= -x if x<0.

|5-15|=|-10| = -(-10) = 10.

0*|-6|= 0 * -(-6)= 0*6=0.

An isosceles trapezoid has a perimeter of 108 metres. Its shorter base measures 11.5 metres and its longer base measures 28.1 me
kati45 [8]

The length of one of the remaining sides is 34.20 meters.

<h3>What is the length?</h3>

A trapezoid is a convex quadrilateral. A trapezoid has at least on pair of parallel sides. the parallel sides are called bases while the non parallel sides are called legs

Perimeter of an isosceles trapezoid =  sum of lengths of sides of a trapezoid

length of shorter base + length of longer base + (2 x legs)

108 = 11.5 + 28.1 + (2 x legs)

108 = 39.60 + (2 x legs)

108 - 39.60 =  (2 x legs)

68.40 =  (2 x legs)

leg = 68.40 / 2

= 34.20 meters

18 POINTS! At the AoPS office, mice vary inversely with cats, that is, mice=k/cats, for some value of k. When there are 3r-19 ca
Blizzard [7]

Answer:

k=30

Step-by-step explanation:

The number of mice vary inversely with cats. This is written as:

Mice \propto \dfrac{1}{Cat} \\Mice = \dfrac{k}{Cat}

When there are 3r-19 cats, there are 2r+1 mice

2r+1 = \dfrac{k}{3r-19}\\$Cross multiply$\\k=(3r-19)(2r+1)

When there are 6r-27 mice, there are r-5 cats.

6r-27 = \dfrac{k}{r-5}\\$Cross multiply$\\k=(6r-27)(r-5)

Taking the values of k above, we have:

k=(3r-19)(2r+1) =(6r-27)(r-5)\\(3r-19)(2r+1) =(6r-27)(r-5)\\6r^2+3r-38r-19=6r^2-30r-27r+135\\$Collect like terms\\6r^2-6r^2+3r+30r-38r+27r-19-135=0\\22r-154=0\\22r=154\\$Divide both sides by 22\\r=7

Therefore:

k=(3r-19)(2r+1) \\=(3*7-19)(2*7+1)\\=(21-19)(14+1)\\=2*15\\k=30
