The perimeter of the triangle is 36 units.
Distance
The distance between two points A(x₁, y₁) and B(x₂, y₂) is given by:
[tex]AB=\sqrt{(y_2-y_1)^2+(x_2-x_1)^2}[/tex]
The coordinate of the triangle is A(0, 0), B(10, 0) and C(5, 12). Hence:
AB = 10 units
[tex]BC=AC=\sqrt{(5-0)^2+(12-0)^2}=13\ units[/tex]
Perimeter of triangle = AB + BC + AC = 10 + 13 + 13 = 36 units
The perimeter of the triangle is 36 units.

Charlie has a collection of books that he wishes to display in a narrow bookcase with shelves of width 56cm. The thickest books are no more than 16cm wide and, when placed side by side, the entire collection takes up 2.4m. Find, with justification, the minimum number of shelves required to guarantee that all of the books can be displayed in the bookcase.
Answers
Answer:
5 shelves
Step-by-step explanation:
Given the following :
Width of shelves = 56cm
Maximum thickness of books = 16cm
When placed side-by-side, the entire collection of books takes up 2.4m
Minimum number of shelves required to guarantee that all of the books can be displayed in the book case.
Entire book collection = 2.4m = (2.4 × 100) = 240cm
Width of shelf = 56cm
In other to guarantee that the bookshelf contains all the books, we can assume that the each book is of maximum width, 16cm
Hence, maximum number of books each shelf can hold with guarantee
Width of shelf / max. Width of book
= 56cm / 16cm = 3.5
Hence, a shelf can hold 3 books with full guarantee.
If books are all 16cm thick, then the number of books ;
240 cm / 16 cm = 15 books
If one shelf can hold 3 books, then,
15/3 = 5 shelves are required to hold the books with maximum guarantee.

Answer : MN =
Answers
Answer:
MN = 4
Step-by-step explanation:
Given that L, M, N are collinear,
LN = 9,
MN = 4x
LM = 5x
Required:
Length of MN
SOLUTION:
To calculate the numerical length of MN, we need to find the value of x.
To find the value of x, generate an equation to solve for x as follows:
[tex] LM + MN = LN [/tex] (segment addition postulate)
[tex] 5x + 4x = 9 [/tex] (substitution)
Solve for x
[tex] 9x = 9 [/tex]
Divide both sides by 9
[tex] \frac{9x}{9} = \frac{9}{9} [/tex]
[tex] x = 1 [/tex]
MN = 4x
plug in the value of x
MN = 4(1) = 4

if angle LMPis 11 degrees more than angle NMP and angle NML is 137 find each measure.
Answers
Answer:
angle NMP = 63°
angle LMP = 74°
Step-by-step explanation:
Let angle NMP be x° . It's given that angle LMP is 11° more than angle NMP. So, angle LMP = x° + 11°
But angle NML = 137°.
So,
angle NMP + angle LMP = 137°
=> x° + x° + 11° = 137°
=> 2x° + 11° = 137°
=> 2x° = 137° - 11°
= 126°
=> x° = 126/2 = 63°
angle NMP = 63°
angle LMP = 63 + 11 = 74°

Perform the indicated operation. 1 and 2/3 plus 5 and 3/8
Answers
Answer:
7 1/24
Step-by-step explanation:
1 2/3+5 3/8=?
first you need to find the least common multiple between 2/3 and 3/8.
the lcm would be 24, so 24 would be your new denominator for both fractions, but the numerators will change to how much you just multiplied each denominator by to get 24. 8x3 is 24, so you would multiply 3x3 to get the new numerator: 9. 3x8 is 24, so you multiply 2x8 to get the new numerator for that fraction:16.
so your new fractions are 1 16/24 + 5 9/24
now you add 16+9=25 (25/24, which becomes 1 1/24), so then you have another whole number: +1, and you add it to 5+1, so no it's 5+1+1=7
so the answer would be 7 1/24

Answers
Answer:
total dogs= 2
total pets= 2+4+5=11
so, the ratio of dogs to all pets = 2/11
Step-by-step explanation:
Based on the number of all animals in the shop as well as the number of dogs, we can infer that the ratio of dogs to the others is 2 : 11
The first thing to do is to find the total number of animals in the shop:
= Dogs + Cats + Hamsters
= 2 + 4 + 5
= 11 animals
The ratio of dogs to the rest of the animals is:
= Number of dogs : Number of animals
= 2 : 11
= 2 : 11
In conclusion, the ratio is 2:11.

Answers
Answer:
LEON (2.1), JASON (2.4), ASHLEY (2.5), MIKA (2.6)
Step-by-step explanation:
To order their perimeter from the least to the greatest, express all perimeters in decimals:
LEON = √17 - 2 = 4.1 - 2 = 2.1
MIKA = 1 + π/2 = 1 + 22/7*½ = 1 + 22/14 = 1 + 1.6 = 2.6
JASON = 12/5 = 2⅖ = 2.4
ASHLEY = 2.5
From least to greatest, we have: LEON (2.1), JASON (2.4), ASHLEY (2.5), MIKA (2.6)

7×2=14+1= 15
15×2=30+1=31
Answer:
Multiply a term by 2 and add 1 to get the next term
Step-by-step explanation:
The first differences of terms are ...
7 -3 = 4
15 -7 = 8
31 -15 = 16
We notice that these increase by a factor of 2. This signifies an exponential sequence. That factor (2) will be the value that each term is multiplied by to get the next. This eliminates the choices "add 4" and "multiply a term by 3 ...".
Trying the remaining two choices, we find that the one that fits is the one shown above.
3+7 ≠ 15, so "the sum of the two preceding terms" doesn't work
2(3) +1 = 7; 2(7) +1 = 15; 2(15) +1 = 31, so "multiply by 2 and add 1" works fine
