Two identical figures with all sides of equal length = Both are square
Solution :
The perimeter of a square is defined as the total length that its boundary covers. The perimeter of any closed geometrical shape is calculated by finding the distance around that shape. For a square, the perimeter can be calculated by finding the sum of all the sides. Since all four sides are equal, it is four times the length of each side of a square. Let us learn about perimeter of square in detail in this article.
Derivation of Perimeter of Square Formula
The perimeter of the square is defined as the total length of the boundary of a square. In order to calculate the perimeter of the square, we will find the sum of all of its sides. Since all sides of a square are equal for a square, with each side measuring "s" units, perimeter will thus be given as,
Perimeter of square = s + s + s + s
⇒ Perimeter of square = 4s, where "s" is the side length of the square.
Squares :
A square is a special kind of rectangle (an equilateral one) and a special kind of parallelogram (an equilateral and equiangular one). A square has four axes of symmetry, and its two finite diagonals (as with any rectangle) are equal. Bisection of a square by diagonal results in two right triangles.
The formula for the perimeter of a square is,
P = Side + Side + Side + Side. Or,
P = 4 × Side.
two identical figures with all sides of equal length the combined perimeter of the figure is 80centimeters
2(4*side ) = 80
8*side = 80
side = 10
length of one side =10

How long would it take to double your principal in an account that pavs 6.5 % annual interest compounded continuously?
It will take 4.63 years to double the principal.
The formula for calculating the amount (A) on a principal (P) invested at the rate of r%, compounded continuously after t years is-
A = P[tex]e^{rt}[/tex]
Here r = 6.5%
= 0.065
Let the principal amount be P,
then the amount after t years = 2P
A = P[tex]e^{rt}[/tex]
2P = P[tex]e^{rt}[/tex]
2P/P = [tex]e^{rt}[/tex]
2 = [tex]e^{0.065t}[/tex]
Taking log on both sides-
Log 2 = log [tex]e^{0.065t}[/tex]
Log 2 = 0.065t log e
Log 2 = 0.065t
0.65t = Log 2t
= log 2/ 0.065t
= 0.301/ 0.065 t
= 4.63
Thus, it will take 4.63 years to double the principal.

A charge of $8.99 is automatically deducted from Ari's bank account each
month for a live TV streaming service. What is the change in Ari's bank
account after 6 months for this service?
Ari loss 53.94% of his account balance for this live tv streaming service.
Given,
The charge for a live tv streaming service that is automatically deducted from Ari's bank account each month = $8.99
This deduction continues for 6 months.
We have to find the change in Ari's bank account after 6 months for this service.
Charge for 1 month = 8.99
Charge for 6 months = 6 × 8.99 = 53.94
That is if Ari had $100 in his account, now after 6 months 53.94% deducted for the tv streaming service charge.
Now, he has an account balance:
100 - 53.94 = 46.06
In terms of amount, he has an account balance of $46.06.
In terms of percentage,
Ari lost 53.94% from his account balance and now he has 46.06% account balance.

1. Show an example of two numbers that are additive inverses.
Step-by-step explanation:
Greetings !
Definition:-In mathematics, the additive inverse of a number a is the number that, when added to a, yields zero. This number is also known as the opposite, sign change, and negation.
For example, the additive inverse of 7 is −7, because 7 + (−7) = 0, and the additive inverse of −0.3 is 0.3, because −0.3 + 0.3 = 0. Similarly, the additive inverse of a − b is −(a − b) which can be simplified to b − a. The additive inverse of 2x − 3 is 3 − 2x, because 2x − 3 + 3 − 2x = 0.

log 5
We need to know about logarithm to solve this problem. The greatest integer that is less than the value of log 5 is 0.
Logarithm is the exponent that is raised to a base to get a certain number. There are a few rules of algorithm, log a+ log b can be written as log ab, log a -log b can be written as log a/b, when a number whose logarithm is being calculated is raised to a certain power then the power can be directly multiplied to the log itself. Logarithm when written as log has a base of 10, the logarithm of a number that is same as it's base is always 1, the log of 1 is always zero, because any nonzero number raised to 0 is 1.We will find the value of log 5 first and then choose the nearest integer that is less than log 5.
log 5=log 10/2 =log 10-log 2=1-0.30=0.7

Find the length
Of the three line segments that form the triangle pictured below. The units of the grid each represent one centimeter.
4. Show your work or discribe how you found the length of the diagonal segment AB
5. Give the x-coordinate of the midpoint of AC. X=?
6.( same thing as 5 just with BC)
7.(same thing as 6,and 5 just with AB)
Step-by-step explanation:
for the lengths of BC and AC we can count the squares, because the lengths of these lines are the sum of the side lengths of each inducing square.
1.
BC = 7 - -2 = 7 + 2 = 9 cm
2.
AC = 13 - 1 = 12 cm
3.
but for AB we cannot do that, because AB consists of the lengths of all the diagonals of the squares. and a diagonal must always be longer than any side.
just look at the triangle : it is clear that AB must be longer than AC.
no, for a line that goes across the grid squares we need other methods.
in our case, we have a right-angled triangle and can use Pythagoras
c² = a² + b²
c being the Hypotenuse (the side opposite of the 90° angle), a and b being the legs of the triangle (enclosing the 90° angle).
AB is in our case the Hypotenuse, and we get
AB² = 12² + 9² = 144 + 81 = 225
AB = sqrt(225) = 15 cm
4.
as explained, we used Pythagoras.
5.
the coordinates for a midpoint between 2 points (x1, y1) and (x2, y2) are simply
((x1+x2)/2, (y1+y2)/2)
A = (13, -2)
B = (1, 7)
C = (1, -2)
midpoint AC = ((13+1)/2, (-2 + -2)/2) = (14/2, -4/2) =
= (7, -2)
the x coordinate is 7.
6.
midpoint BC = ((1+1)/2, (7+ -2)/2) = (2/2, 5/2) = (1, 2.5)
the y coordinate is 2.5
7.
midpoint AB = ((13+1)/2, (-2+7)/2) = (14/2, 5/2) =
= (7, 2.5)
The endpoints of CD are C(-8, -1) and D(2,4). Find the coordinates of midpoint M

60 ≤ x ≤ 70 stuffed duck

We have 75 possible numbers equally likely to select, and 1111 outcomes where we win the stuffed duck
60, 61, 62, 63, 64, 65, 66, 67, 68, 69 and 70
Therefore, the probability of winning a stuffed duck is
p(60 ≤ x ≤ 70) = 11/75= 0.146
The event of not winning a duck or a banana is that of winning the consolation prize, that is, picking a number 1 ≤x ≤ 60.
Those are 59 equally likely to occur outcomes. Then we have
c= 59/75= 0.786
To check whether this result is right, we can use the complementary events law. That is, the probability of not winning a duck or a banana is 11 minus the sum of the probabilities of winning a duck or a banana. Mathematically this is
p (1 ≤ x ≤ 60) = 1-(p (60≤x≤70)+p(70≤x≤75)
