X + y = 24
x - y = 2
-------------add
2x = 26
x = 26/2
x = 13
x - y = 2
13 - y = 2
-y = 2 - 13
-y = - 11
y = 11
ur numbers are 11 and 13
Answer:
A. P = 4s
B. P = 24 cm
Step-by-step explanation:
Perimeter of a shape is the sum of all the length of sides of the shape.
Let the perimeter of the square be represented by P, and the length of its sides by s.
A. P s
P = ks
where k is the proportionality constant.
But for a square the length of sides are equal, thus;
P = s + s + s + s
= 4s
So that,
4s = ks
⇒ k = 4
∴ P = 4s
B. Given a square of side length 6 cm, determine its perimeter.
P = 4s
But, s = 6 cm
P = 4 x 6
= 24
P = 24 cm
The perimeter of the given square is 24 cm. And the drawing is herewith attached to this answer for clarifications.
Answer:
1.9
Step-by-step explanation:
The MAD is found by <em>finding the mean, then finding how far each number is to the mean, then finding the mean of that.</em>
The mean is: <em>(1 + 8 + 3 + 1 + 3 + 3 + 7 + 5 + 1 + 3)/10</em> = 35/10 = <em>3.5</em>
The distances of all of the numbers is <em>(absolute value of the difference between 3.5 and the number) </em>: <em>2.5, 4.5, 0.5, 2.5, 0.5, 0.5, 3.5, 1.5, 2.5, 0.5</em>
The mean of those is: <em>(2.5 + 4.5 + 0.5 + 2.5 + 0.5 + 0.5 + 3.5 + 1.5 + 2.5 + 0.5) /10</em> = 19/10 = 1.9
The answer should be 2263611.69, hopefully that helps.
