When a whole number is multiplied by 10 to the power of 2, how does the placement of the decimal point change?
a) It moves two places to the right.
b) It moves ten places to the right.
c) It moves two places to the left.
d) It moves ten places to the left.
Answer: A) moves two places to the right
Example:
[tex]2.567 * 10^2 = 2.567 * 100 = 256.7[/tex]
The positive exponent over the 10 tells us how many places to move to the right. If the exponent was negative, then we'd move to the left. This only works when the base is 10.

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

Mrs. Smith spent $50 more at a store than mrs. Jones. Combined they spent at most $250. What is the most they each could have spent?
By working with inequalities, we will see that:
Mrs. Jones can spend between $0 and $100.Mrs. Smith can spend between $50 and $150.How much each spent?Let's define:
S = amount that Mrs. Smith spent.J = amount that Mrs. Jones spentWe know that Mrs. Smith spent $50 more at a store than Mrs. Jones, then:
S = J + 50
And together they spent at most $250, then:
S + J ≤ 250
Now, replacing the equation in the inequality, we get:
(J + 50) + J ≤ 250
2*J + 50 ≤ 250
2*J ≤ 250 - 50
2*J ≤ 200
J ≤ 200/2
J ≤ 100
So Mrs. Jones spent at most 100 dollars.
And Mrs Smith spent $50 more than that, so we can write the inequality.
50 ≤ S ≤ 150
She spends between $50 and $150.

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.
A cyclist rides her bike at a rate of 8 miles per hour. What is this rate in kilometers per hour? How many kilometers will the cyclist travel in 2 hours? In your computations, assume that 1 mile is equal to 1.6 kilometers. Do not round your answers. Rate:km/hDistance traveled in 2 hours:km
Given:
1 mile = 1.6 km
So, 8 miles per hour in kilometers per hour is given by:
[tex]\frac{1}{8}=\frac{1.6}{x}[/tex]Where x = # of kilometers
So, solve for x:
[tex]\begin{gathered} x\cdot1=1.6\cdot8 \\ x=12.8 \end{gathered}[/tex]This is 12.8 km per hour
Next, the distance traveled in 2 hours is:
[tex]rate=\frac{distance}{time}\rightarrow distance=rate\times time[/tex]Substitute the values:
[tex]distance=12.8\times2=25.6[/tex]Answer:
Rate: 12.8 km/h
Distance traveled in 2 hours: 25.6 km
Ben is a coal miner and spends most of his workday in an underground mine. Which is the most likely depth he is at while doing his job?
Answer:-900 feet. I think this is correct so don't use it unless you think its right
Step-by-step explanation:
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
Real world compositionsShoe sizes are marked differently in many countries. In Japan, a shoe size is 16 more than the size in the United States. In Korea, a shoe size is 224 more than the size in Japan. Determine the function of the U.S. size of a shoe in terms of the shoe size in Korea. What is the U.S. shoe size of a shoe that is 250 in Korea? Solve using composite functions
To solve this exercise, we define the following variables:
• j = Japan size of shoes,
,• u = United Sates size of shoes,
,• k = Korea size of shoes.
From the statement of the problem, we know that:
0. In Japan, shoe size is 16 more than the size in the United States →, j = 16 + u,,
,1. In Korea, shoe size is 224 more than the size in Japan →, k = 224 + j.
We must find a function for the U.S. size of a shoe (u) in terms of the shoe size in Korea (k).
1) From point 1, we have:
[tex]\begin{gathered} j=16+u, \\ u=j-16. \end{gathered}[/tex]2) From point 2, we have:
[tex]\begin{gathered} k=224+j, \\ j=k-224. \end{gathered}[/tex]Replacing the expression of j in terms of k in the expression of u, we get:
[tex]u=j-16=(k-224)-16=k-240.[/tex]Replacing the value k = 250 in the last equation, we get:
[tex]u=250-240=10.[/tex]Answer
The U.S. shoe size of a shoe that is 250 in Korea is equal to 10.

Solve each system of equations please show your work! 3x+y-2z=22 x+5y+z=4 x=-3z
The solution of the system of equations are;
⇒ x = - 6 , y = 44 and z = 2
What is substitution method?
To find the value of any one of the variables from one equation in terms of the other variable is called the substitution method.
Given that;
The system of the equations are,
3x + y - 2z = 22 .... (i)
x + 5y + z = 4 .... (ii)
x = - 3z .... (iii)
Now,
Solve the equations as;
Substitute x = - 3z in both equations, we get;
⇒ 3x + y - 2z = 22
⇒ 3 × -3z + y - 2z = 22
⇒ - 9z + y - 2z = 22
⇒ - 11z + y = 22 .... (iii)
And, x + 5y + z = 4
- 3z + 5y + z = 4
5y - 2z = 4 ... (iv)
Solve equation (iii) and (iv) we get;
⇒ y = 44 and z = 2
So, x = - 3z
⇒ x = - 3 × 2
⇒ x = - 6
Thus, The solution of the system of equations are;
⇒ x = - 6 , y = 44 and z = 2

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
∠A and \angle B∠B are vertical angles. If m\angle A=(x+12)^{\circ}∠A=(x+12)
∘
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°
