The perimeter of any shape is the distance all the way around it.
For a triangle, it's the sum of the three side lengths.
I would normally copy them into my answer and then add them up.
But you've set them up in such a beautiful table in the question,
you can just look at that list and add them up.
Add up all the x's : x + x + x = 3x
Add up all the plain numbers: -3 + 2 + 4 = 3
There's your perimeter . . . . . 3x + 3 .
Answer:
A scatter plot is a graph with the points listed
Step-by-step explanation:
a positive number for x is to the right of the origin point (0,0) an negative is the opposite
a postive number for y is going up away from the origin and a negative is going down instead
somthing like this picture below
Answer:
8
Step-by-step explanation:
45/6=7.5
so 8 boxes
Answer:
1.84ft
Step-by-step explanation:
From the figure attached,
AB = Height of the window = 15ft
Let the distance between the base of the housr and the fence 'C' = xft
If the angle of depression = 7°
Then angle of elevation of the top of the fence from the house = 7°
Now from right triangle ABC,
tan7° = x/15
x = tan7°×15
x = 0.1227×15
x = 1.84ft
Therefore, distance of the house from the fence is 1.84ft
The Venn diagram
is attached in the figure.
Total number of students = 32
Number of students have a dog = 0.5 *32 = 16
Number of students have a cat = (3/8) * 32 = 12
Number of students have other pets = 6
Number of students have no pets = 5
From the Venn diagram:
Number of students have a dog = x+y+z+10
Number of students have a cat = x+z+w+9
Number of students have other pets = y+z+w+2
Total number
of students have no pets = 32 – (x+y+z+w+21)
So, as a
conclusion for the above information
x+y+z+10 =
16 (1)
x+z+w+9 = 12 (2)
y+z+w+2 = 6 (3)
32 – (x+y+z+w+21)
= 5 (4)
By solving
the system of equations to find x , y , z , w
x = 2 , y =
3 , z = 1 , w = 0
By using Venn
diagram
Number of students <span>have all three types of pets</span> = z = 1 student
