Using the bankers rule, find the simple interest on 18,000 pesos at 17.25% from Feb.4 to Apr 21 of the same leap year.
From the question
By the bunkers rule
[tex]I=\text{PRT}[/tex]P = 18,000
R = 17.25% = 0.1725
For the time
Since the year is a leap year then
February has 29 days
Hence
From Feb.4 to Apr 21 implies
The number of days left in Feb. = 25
Number of days in March = 31
Number of days for April = 21
Therefore, Total number of days = 25 + 31 + 21 = 77
By Bankers rule, total days for the year will be 360
Hence the interest is
[tex]\begin{gathered} I=18000\times0.1725\times\frac{77}{360} \\ I=18000\times0.1725\times0.2139 \\ I=664.16 \end{gathered}[/tex]Therefore, the interest is 664.16

Amanda and Jeremiah are standing on the same side of a large lake. They are separated by a horizontal distance of 4000 ft. Both Amanda and Jeremiah can see a helicopter that is directly above the horizontal distance between them. Amanda’s angle of elevation to see the helicopter is 60 and Jeremiah’s angle of elevation to see it is 30. 1.What is the distance between Amanda and the helicopter?
Explanation: First of all we need to know if our triangle is a right triangle (has one 90° inner angle) to be able to use the law of sines to calculate the distance between Amanda and the helicopter.
Step 1: Once we know that the sum of all inner angles of a triangle is equal to 180° we can calculate the unknown angle as follows
As we can see above the missing inner angle is 90° which means it is a right triangle.
Step 2: Now we can use the law of sines as follows
once sin (90°) = 1 and sin (30°) = 0.5, let's calculate "x" below
[tex]\begin{gathered} \frac{x}{sin(30)}=\frac{4000}{sin90} \\ x=\frac{4000*0.5}{1} \\ x=2000ft \end{gathered}[/tex]Final answer: As we can see above, the final answer is 2000 ft

The area of the wall whose length is 4y+8 and the height is 4y is 16y^2 + 32y.
How area is calculated?
Area is a phrase used to describe how much room a 2D form or surface occupies. Area is measured in square units, such as cm2 or m2.
The area of a form is computed by dividing its length by its breadth.
It is given that the length of the wall is 4y+8 and height of the wall is 4y.
From this given information, we can conclude that the wall is rectangle.
Formula to calculate the area of rectangle is:
Area of rectangle = length x breadth
Putting the value given in the question:
Area of the wall = (4y+8)(4y)
Area of the wall = 16y^2 + 32y
Therefore, the area of the wall is 16y^2 + 32y

72b384 is a number in which one of its digits is 'b'. if the number is a multiple of 9, what is the numerical value of 'b'?
Answer:
3
Step-by-step explanation:
Hello!
A simple way to find if the number is a multiple of 9 is if the sum of the digits in the number is a multiple of 9, then the number itself is a multiple of 9.
So that means: 7 + 2 + b + 3 + 8 + 4 is a multiple of 9
If we add it up we should get: 24 + b
The multiples of 9 include 9,18,27,36,45,54....., and the closest multiple of 9 to 24 is 27. Therefore, the missing digit should be 3, as 27 - 24 is 3.
The next closest numbers would be 18 and 36, but you would need to add a negative number to get 18, and a two-digit number to get 36.

Given the interval of the distribution as
[tex]5-5.76[/tex]a) To find the mean, we will calculate the mid-value of the interval, this is shown below
[tex]\operatorname{mean}=\frac{5+5.76}{2}=\frac{10.76}{2}=5.38[/tex]Hence, the mean is 5.38
b) To find the standard deviation
[tex]\begin{gathered} SD=\sqrt[]{\frac{(b-a)^2}{12}} \\ b=5.76 \\ a=5 \\ SD=\sqrt[]{\frac{(5.76-5)^2}{12}} \\ =\sqrt[]{\frac{0.76^2}{12}}=0.2194 \end{gathered}[/tex]Hence, the standard deviation is 0.2194
c) The probability that the child will be older than 5 years will be
[tex]P(older\text{ than 5 years)=}\frac{5.76-5}{5.76-5}=\frac{0.76}{0.76}=1.0[/tex]Hence, the probability that the child will be older than 5 years is 1.0
d) The probability that the child age is between 5.4 and 5.6 years old will be
[tex]P(\text{ between 5.4 and 5.6 years old)=}\frac{5.6-5.4}{5.76-5}=\frac{0.2}{0.76}=0.2632[/tex]Hence, the probability that the child age is between 5.4 and 5.6 years old is 0.2632

I need to know the answer but I need to know how to get it and work it out
Let's start by completing the first table.
The questions gives the depth in two times:
- 2 hours after start -> 64 inches of water
- 4 hours after start -> 48 inches of water
From this, we can identifythe units:
- for time, we will use hours
- for depth, we will use inches
The first given values are:
- for time, 2
- for depth, 64
The second given valuesa are:
- for time, 4
- for depth, 48
So, the table is:
Quantity Name | Time | Depth of Pool
Unit | hour | inch
Given Value 1 | 2 | 64
Given Value 2 | 4 | 48
Now, we need to calculate the slope, which can be done using the given points and the equation:
[tex]\begin{gathered} m=\frac{y_2-y_1}{x_2-x_1} \\ m=\frac{48-64}{4-2} \\ m=\frac{-16}{2} \\ m=-8 \end{gathered}[/tex]So, the slope is -8 inches per hour.
The interceptwe the b in the equation:
[tex]y=mx+b[/tex]Where y is the depth and x is the time. So, using the first given values and the slope, we can find b:
[tex]\begin{gathered} 64=-8\cdot2+b \\ 64=-16+b \\ b=64+16 \\ b=80 \end{gathered}[/tex]Thus, the intercept is 80 inches.
So, the formula we have for the pump is:
[tex]y=-8x+80[/tex]Using it, we can answer questions 1 and 2:
1. After 6 hours means x = 6, so:
[tex]\begin{gathered} y=-8\cdot6+80 \\ y=-48+80 \\ y=32 \end{gathered}[/tex]So, y = 32, thus, the depth of the water will be 32 inches.
2. The level 24 inches mean y = 24, so:
[tex]\begin{gathered} 24=-8x+80 \\ 8x=80-24 \\ 8x=56 \\ x=\frac{56}{8} \\ x=7 \end{gathered}[/tex]Thus, x = 7, and the water will be at 24 inches after 7 hours.
Use 2 methods to predict the output for an input of 200.
Given a table represents a relation between x and y
As shown, the change of (x) and (y) vary with a constant rate
So, the table represents a linear function
The general equation will be: y = m * x + b
where (m) is the slope, (b) is the value of y when (x=0)
So, from the table, when x = 0 , y = 25
The slope will be as follows:
[tex]m=\frac{30-25}{1-0}=\frac{5}{1}=5[/tex]So, the equation will be:
[tex]y=5x+25[/tex]When the input = 200, x = 200
So, substitute with (x) to find the output (y)
[tex]y=5\cdot200+25=1000+25=1025[/tex]So, the answer will be:
For an input 200, the output is 1025
===================================================
Another method to solve using the arithmetic sequence.
As shown in the table consider (x) represents the number of terms
So, (y) will be an arithmetic sequence
The first term = a = 30
The common difference = d = 35 - 30 = 5
the general rule of the arithmetic sequence is:
[tex]y_{}=a+d(x-1)[/tex]substitute with (a) and (d)
[tex]y=30+5(x-1)[/tex]When x = 200
[tex]y=30+5(200-1)=30+5\cdot199=1025[/tex]So, for an input 200, the output = 1025

Given the Linear Equation:
[tex]5x+y=3x+2[/tex](a) You need to solve for "y", in order to rewrite it in Slope-Intercept Form, because that form is:
[tex]y=mx+b[/tex]Where "m" is the slope of the line and "b" is the y-intercept.
Then, you get:
[tex]\begin{gathered} y=-5x+3x+2 \\ y=-2x+2 \end{gathered}[/tex]Notice that:
[tex]\begin{gathered} m=-2 \\ b=2 \end{gathered}[/tex](b) You can graph the line by finding the x-intercept and the y-intercept. You already know that the y-intercept is:
[tex]b=2[/tex]Then, in order to find the x-intercept, you need to substitute this value of "y" into the equation and then solve for "x":
[tex]y=0[/tex]Because the value of "y" is zero when the line intersects the x-axis.
Therefore, you get:
[tex]\begin{gathered} y=-2x+2 \\ 0=-2x+2 \\ -2=-2x \\ \\ \frac{-2}{-2}=x \\ \\ x=1 \end{gathered}[/tex]Now you know that the line passes through these points:
[tex](1,0),(0,2)[/tex]Hence, you can graph it.
Therefore, the answers are:

and m\angle B=(6x-8)^{\circ}∠B=(6x−8)
∘
, then find the measure of \angle B∠B
Measure of ∠B = 16°
∠A and ∠B are Vertical angles with ∠A = x+12° and ∠B = 6x-8°.
Vertical angles are angles formed between two lines at the intersection of them and are opposite to each other.
Also measures of Vertical angles are equal.
Now to find the measure of ∠B, we need to find x.
So here, ∠A = ∠B
⇒ x+12° = 6x-8°
⇒ 6x - x = 12 + 8
⇒ 5x = 20
⇒ x = 4
Hence, ∠B = 6x-8° = 6 x 4 -8 = 16°
So measure of ∠B = 16°

Step-by-step explanation:
Solve the linear system using the elimination method. Type youranswer as an ordered pair in the form (#,#). 6x + 5y = -15-2x – 3y = 17
1) Solving that linear system using the elimination method, we'll proceed this way.
1.1 Choose one variable to be canceled out firstly. Let's choose the x variable:
6x + 5y = -15
-2x -3y= 17 Multiply this whole equation by 3
6x + 5y = -15
-6x -9y= 51 Add both equations
----------------------
0 -4y =36 Divide both sides by -4
y = -9
2) Now let's plug into any equation, usually the one with smaller numbers y= -9
-2x -3(-9) = 17
-2x +27 = 17 Subtract 17 from both sides
-2x =17-27
-2x = -10 Divide both sides by -2
x= 5
3) So the solution is (5, -9)
