11 + 16 > 26
11 + 26 > 16
16 + 26 > 11
16 - 11 < 26
26 - 16 < 11
26 - 11 < 16

Since all the inequalities above are true, there is exactly one triangle with those side lengths.

GarryVolchara [31]
<span>What we are asked to find out is speed per hour. To find speed, divide distance by time. Distance is 3000 ft and time is 1 3/4 hr. To make calculations easier, let us convert time into minutes. 1 hour is 60 minutes and 3/4 hour is 45 minutes. So total minutes is 105. Now let us divide 3000 by 105. We get 28.57 ft per minute. Now multiply this number by 60 to convert speed per minute into speed per hour. 28.57 * 60 = 1714 ft in 1 hour.</span>

Johan found that the equation –2|8 – x| – 6 = –12 had two possible solutions: x = 5 and x = –11. Which explains whether his solu
lutik1710 [3]

Answer:

we have two solution x = 5 and x = 11

but in given problem x = 5 and x = –11

thus, only one of his solution x = 5 is correct

Step-by-step explanation:

Given

–2|8 – x| – 6 = –12

adding 6 both sides

–2|8 – x| – 6 +6= –12 +6

–2|8 – x|  = –6

dividing both side by -2

–2|8 – x| /-2 = –6/-2

=>|8 – x|  = 3

we know that

in modulus function |Y| = -y or y

Thus

|8 – x|  = 3

can be written as

8-x = 3   or          8- x = -3

8-x-3 = 0  or      8-x+3 = 0

5-x = 0     or      11 -x = 0

x = 5       or x = 11

thus, we have two solution x = 5 and x = 11

but in given problem x = 5 and x = –11

thus, only one of his solution x = 5 is correct

Why is 82 a composite number
AfilCa [17]

Answer:

Why is 82 a composite number? A composite number is a number that can be divided evenly by more numbers than 1 and itself. ... The number 82 can be evenly divided by 1, 2, 41 and 82, with no remainder. Since 82 cannot be divided by just 1 and 82, it is a composite number.
