The side of the square shape is calculated as 4cm.
What is meant by square?A square is a subset of a rectangle (an equilateral rectangle) and a subset of a parallelogram (an equilateral and equiangular one).
A square has 4 axes of symmetry and two finite diagonals that are equal (as with any rectangle). A square divided by a diagonal yields two right triangles.As, a wire is 32-centimetre-long,
If we cut this same wire in half, the result should be 1/2 of total of
32/2 = 16
In addition, the square has four equal sides.
16/4 = 4
As a result, the square's sides should be 4 cm.

Answer:
a = 0 and b = literally any number
Step-by-step explanation:
because anything to the power of 0 = 1,
so e.g. 2^0 = 1 or 8^0 = 1
this is just a rule in powers that you just have to know

A florist arranges 4 flower arrangements in 92 minutes.
At this rate, how many many flower arrangements are made in 207 mintues?
Enter your answer in the box.
Answer:
[tex]\boxed {\boxed {\sf 9 \ arrangements }}[/tex]
Step-by-step explanation:
Let's set up a proportion using the following setup:
[tex]\frac{arrangements}{minutes} =\frac{arrangements}{minutes}[/tex]
We know that the florist can arrange 4 in 92 minutes.
[tex]\frac{4 \ arrangements}{92 \ minutes} = \frac{arrangements}{minutes}[/tex]
We don't know how many the florist can arrange in 207 minutes, so we say x arrangements can be completed in 207 minutes.
[tex]\frac{4 \ arrangements}{92 \ minutes} = \frac{ x \ arrangements}{ 207 \ minutes}[/tex]
[tex]\frac{4}{92} =\frac{x}{207}[/tex]
Solve for x by isolating it on one side of the proportion.
x is being divided by 207. The inverse of division is multiplication. Multiply both sides of the proportion by 207.
[tex]207*\frac{4}{92}=\frac{x}{207}*207[/tex]
[tex]207*\frac{4}{92}=x[/tex]
[tex]207*0.0434782609=x[/tex]
[tex]9=x[/tex]
The florist can arrange 9 arrangements in 207 minutes.

Describe the shaded areas.
9514 1404 393
Answer:
the difference of 2 or 3 rectangles
Step-by-step explanation:
In every case, the "shaded" area can be computed by finding the area of a "bounding" rectangle, and subtracting the areas of the rectangular cutouts that give the figure its shape.
(a) The cutout is the white space at upper right. (Insufficient dimensions are given.)
(b) The cutout is the white space at lower left. The bounding rectangle is 8×7, and the cutout is 4×3.
(c) The cutout is the rectangle in the middle. The bounding rectangle is 13×7, and the cutout is 4×1.
(d) The cutouts are the rectangles on either side. They could be considered as a single unit. The bounding rectangle is 20×25; the cutouts have a total width of 16 and a height of 20, so total 16×20.
(e) Similar to (d), the cutouts are the white spaces on either side. The bounding rectangle is 14×12. The cutouts total 12 in width and 3 in height, so total 12×3.
__
You will note in (d) and (e) that the dimensions of the cutouts have something in common with the dimensions of the bounding rectangle. This means the problem can be simplified a little bit by factoring out that common factor. In (e), for example, 14×12 -(12×3) = 12(14 -3) = 12×11

Vhat is the annual interest rate on a loan of
25,500 if the interest payments are $956.25
emiannually on the full loan amount?
The annual interest rate on a loan of $ 25,500 if the interest payments are $ 956.25 will be equal to 3.75 %.
We are given that the principal loan amount is equal to $ 25,500
That is
Principal = p = $ 25,500.
The interest payments is $ 956.25
That is the amount of interest = SI = $ 956.25.
Let the rate of interest on the loan amount be r.
Time period = t = 1
Simple Interest = p r t / 100
956.25 = 25,500 × r × 1 / 100
956.25 = 255 r
r = 956.25 / 255
r = 3.75 %
Therefore, the annual interest rate on a loan of $ 25,500 if the interest payments are $ 956.25 will be equal to 3.75 %.

Josiah and Kiri are each saving money.
Josiah starts with `\$100` in his savings account and adds `\$5` per week. Kiri starts with `\$40` in her savings account and adds `\$10` each week.
After `4` weeks, who has more money in their savings account?
Answer:
A.Josiah
5×4= 20+100=120
10×4=40+40=80
120 is more than 80
After 4 weeks , Josiah has 40 dollars more in his savings account.
Given :
Josiah starts with $100 in his savings account and adds 5 per week.
Let x be the number of weeks they started saving
Total money in savings account = 5 (number of weeks) + initial amount
Total money = [tex]5x+100[/tex]
Kiri starts with 40 in her savings account and adds 10 each week.
Total money = 10x+40
Now we need to find out how much money each have after 4 weeks
lets replace x by 4
Josiah have [tex]5(4)+100=120[/tex]
Kiri have [tex]10(4)+40= 80[/tex]
120-80=40
So , Josiah have 40 dollars more in his savings account.

The value of y varies directly with x. When the value y is ⅗, the value of x is 0.125. What is the value of x when the value of y is 12?
Answer:
x = 2.5
Step-by-step explanation:
y varies directly with x means the times that y increases, the times x increases and vice versa.
If y increases from 3/5 to 12 is being increased:
12 / 3/5 = 20 times
Thus, the value of x is being increased by definition, also 20 times. The value of x is:
x = 0.125 * 20 = 2.5
x = 2.5A lie-detector works correctly with 80% probability when the person is lying, and with 90% probability when the person is not. Assume that in a given court, typically 70% of the people who have to be tested with the lie-detector do not say the truth. On the long run, which percentage of time does the lie detector make a mistake?
Answer:
the time percentage is 17%
Step-by-step explanation:
The computation of the time percenatge in the case when the detector lie and done with the mistake is as follows:
L denotes the event in which a person is lying.
NL denotes the event in which a person is not lying.
C denotes the event in which that lie detector works correctly
NC denotes the event in which lie detector is not working correctly
Now
P(C|L) =0.8
And,
P(NC|L) is
=1 - .8
= 0.2
P(C|NL) =0.9
P(NC|NL) is
= 1 -.9
=.1
P(L) = 0.7
P(NL) is
= 1 - .7
= .3
Now
P(NC) =P(NC|L) × P(L) + P(NC|NL) × P(NL)
=. 2 × .7 + .1 ×.3
=. 14+.03
= 0.17
Hence, the time percentage is 17%
The gross weekly sales at a certain super market are a Gaussian random with mean $2200 and standard deviation $230. Assume that the sales from week to week are independent.
A) Find the probability that the gross sales over the next two weeks exceed $5000.
B) Find the probability that the gross weekly sales exceed $2000 in at least 2 of the next 3 weeks.
Answer:
A) P(Z > 5000) = 0.0322
B) P( Y = 2 or 3) ≅ 0.9032
Step-by-step explanation:
From the given information;
Suppose the sales for the first week are denoted by X and the sales for the second week are denoted by Y.
Then;
X & Y are independent and they follow a normal distribution.
i.e.
[tex]XY \sim N(\mu,\sigma^2)[/tex]
[tex]XY \sim N(2200,230^2)[/tex]
If we set Z to be equal to X+Y
Then, [tex]Z \sim N(2 \times 2200,2 \times 230^2)[/tex] since two normal distribution appears normal
[tex]Z \sim N(4400,105800)[/tex]
So;
[tex]P(Z > 5000) = 1 - P( Z< \dfrac{x = \mu}{\sqrt{\sigma}})[/tex]
[tex]P(Z > 5000) = 1 - P( Z< \dfrac{5000-4400}{\sqrt{105800}})[/tex]
[tex]P(Z > 5000) = 1 - P( Z< \dfrac{600}{325.2691})[/tex]
[tex]P(Z > 5000) = 1 - P( Z< 1.844626495)[/tex]
[tex]P(Z > 5000) = 1 - P( Z< 1.85)[/tex]
From the Z - tables;
P(Z > 5000) = 1 - 0.9678
P(Z > 5000) = 0.0322
B)
Let Y be the random variable that obeys the Binomial distribution.
Y represents the numbers of weeks in the next 3 weeks where the gross weekly sales exceed $2000
Thus;
[tex]Y \sim Bin(3,p)[/tex]
where;
[tex]p = 1 - P( Z < \dfrac{2000-2200}{230})[/tex]
[tex]p = 1 - P( Z < \dfrac{-200}{230})[/tex]
p = 1 - P( Z < - 0.869565)
From the Z - tables;
p = 1 - 0.1924
p = 0.8076
Now;
P(Y ≥ 2) = P(Y = 2) + P( Y =3 )
Using the formula
[tex]P(X = r ) = ^nC_r \times p^r \times q ^{n-r}[/tex]
[tex]P( Y = 2 \ or \ 3) =^ 3C_2 \times 0.8076^2 \times ( 1- 0.8076) ^ {3-2} + ^ 3C_3 \times 0.8076^3 \times ( 1- 0.8076) ^ {3-3}[/tex]
[tex]P( Y = 2 \ or \ 3) =\dfrac{3!}{2!(3-2)!} \times 0.8076^2 \times ( 0.1924) ^ 1 + \dfrac{3!}{3!(3-3)!}\times 0.8076^3 \times ( 0.1924) ^ {0}[/tex]

find angles FAB and BAC
Answer:
m<FAB = 75°
m<BAC = 105°
Step-by-step explanation:
First, find the value of x.
(13x - 3)° = (3x + 2)° + 55° (exterior angle theorem of a ∆)
Solve for x
13x - 3 = 3x + 2 + 55
13x - 3 = 3x + 57
Collect like terms
13x - 3x = 57 + 3
10x = 60
Divide both sides by 10
x = 6
✔️m<FAB = 13x - 3
Plug in the value of x
m<FAB = 13(6) - 3 = 78 - 3
m<FAB = 75°
✔️m<BAC = 180 - m<FAB (angles on a straight line/supplementary angles)
m<BAC = 180 - 75 (substitution)
m<BAC = 105°
A point travels East 3 spaces and South 8 spaces.Write the description in algebraic terms.
Answer:
A point travels East 3 spaces and South 8 spaces.
Algebraic equation
[tex]P'(x,y) = (x+3, y-8)[/tex]
Step-by-step explanation:
From the viewpoint of Linear Algebra, the description can be described by means of translation, which is defined as:
[tex]P'(x,y) =P(x,y) +T(x,y)[/tex] (1)
Where:
[tex]P(x,y)[/tex] - Initial position of the traveller, dimensionless.
[tex]T(x,y)[/tex] - Translation vector, dimensionless.
[tex]P'(x,y)[/tex] - Final position of the traveller, dimensionless.
Let suppose that [tex]y > 0[/tex] represents the number of steps to the north, and [tex]x> 0[/tex], the number of steps to the east.
If we know that [tex]P(x,y) =(x,y)[/tex] and [tex]T(x,y) = (3, -8)[/tex], then the resulting equation is:
[tex]P'(x,y) = (x,y) +(3,-8)[/tex]
[tex]P'(x,y) = (x+3, y-8)[/tex]
