Answer: The population after five years = 9967
Step-by-step explanation:
The exponential equation for population decay : [tex]P=A (1-r)^t[/tex], where A = initial population r= rate of decay , t= time
Given: A= 42000, r= 25%= 0.25, t= 5
then
[tex]P=42000(1-0.25)^5\\\\=42000(0.75)^5\\\\=42000(0.2373046875)\\\\\approx9967[/tex]
Hence, The population after five years = 9967

If 9/10 is multiplied by 8/9 , will the product be greater than either of the two factors?
Answer:
No, both of the numbers are less than one whole and when you multiply them (I got 4/5) 4/5 is less than both of the factors.
Answer:
No
Step-by-step explanation:
It will not be because when a number is numtiplied by one, it stays the same. However, both of these are numbers less than 1, so the product will be smaller

Get the variable by itself on one side of the inequality sign. Option D
How to determine the meaningIsolating a variable in an equation or inequality refers to changing it so that it is on its own on one side of the equation or inequality sign.
In order to remove any additional terms or factors that are affecting the variable, this entails applying different operations to both sides of the equation or inequality, such as addition, subtraction, multiplication, or division.
The objective is to make the inequality or equation simpler so that the variable can be solved more easily.

Find the median for the number of pencils.
Answer:
The median is 2
Step-by-step explanation:
Here, we want to get the median for the number of pencils
Firstly, we have to write out the numbers that form the box plot ; we have this as;
1,1,1,2,2,2,2,3,3,5
the median is sum of the 5th and 6th term divided by 2
The 5th term is 2
The 6th term is 2
So the median is;
(2 + 2)/2
= 4/2 = 2

Roy hit 3 less than 4 times the number of balls during baseball practice than Joe did. Together the boys hit 52 balls. How many balls did Joe hit?
Answer:
Joe hit 11 balls Roy hit 41
Step-by-step explanation
Joe = J
Roy = 4J-3 (4times Joe less 3)
J+ 4J-3 = 52
5J -3 = 52
Add 3 on both sides
5J = 55
Divide both sides by 5
J= 11
Joe = 11
11X4 = 44
44-3 = 41
Roy 41
11+41 = 52
The side of polygone have length 5,7,8,11&9, the perimeter of similar polygone is 75cm ,finde the length of the side of large polygon?
Answer:
The side lengths of the larger polygon are;
15 cm
20.625 cm
16.875 cm
9.375 cm
13.125 cm
Step-by-step explanation:
Firstly, we need to calculate the perimeter of the first polygon
Mathematically, we can get this by adding the side lengths together
We have this as;
5 + 7 + 8 + 11 + 9
= 40 cm
so we have the ratio of the lengths of both as;
75 cm/40 cm = 1.875
Now, we simply will multiply the lengths of the smaller polygon by 1.875
So we have the side lengths of the bigger polygon as;
1.875 * 5 = 9.375 cm
1.875 * 7 = 13.125 cm
1.875 * 8 = 15 cm
1.875 * 9 = 16.875 cm
1.875 * 11 = 20.625 cm

if you subtract 12 from my number and multiply the difference by -6 the result is -90 what is my number
Answer:
n must be 27
Step-by-step explanation:
Let this number be x. Then -6(n - 12) = -90.
Dividing both sides by -6 yields n - 12 = 15.
Add 12 to both sides.
Then n must be 27.
Check: subtract 12 from 27; this yields 15. Now multiply this result by -6. The result is -90, which was expected.
What is the area of the shaded portion of the trapezoid in the figure, in terms of? The figure is not drawn to scale. All of the given measurements are in feet.
Answer:
(150-36π) ft^2
Step-by-step explanation:
we need to subtract the area of the circle from the area of the trapezoid to find the area of the shaded region.
area of circle=πr^2=π6^2=36π ft^2
area of trapezoid=(1/2)(a+b)h=(1/2)(12+13)12=150 ft^2
so, the area of trapezoid-area of circle=(150-36π) ft^2

Multiply 6/5 by the reciprocal of (-3/8)
Answer:
-48/15, simplified to -16/5
Step-by-step explanation:
The reciprocal of -3/8 is -8/3. So the equation will be 6/5 x -8/3. Multiply numerators then multiply denominators to get -48/15. This can simplify to -16/5 by dividing both by 3.
Answer:
Step-by-step explanation:
hello :
6/5 by the reciprocal of (-3/8) means : ( 6/5 )(-8/3) = - 48/15 = -16/5

Awad claims that when m is a negative integer and n is a positive integer, n - m is always negative. Is Awad’s claim true or false? Explain your reasoning. If it is true, give an example to support his claim. If it is false, give a counterexample. Explain your reasoning..
Answer:
False
Step-by-step explanation:
False, because whenever you subtract a negative number, you always end up adding because two negatives make a positive. Lets say n is 4 and m is -3, 4-(-3) is going to turn into 4+3=7.
The Awad'claims that "when m is a negative integer and n is a positive integer, n - m is always negative". which is false.
What is the number system?A number system is defined as a way to represent numbers on the number line using a set of symbols and approaches. These symbols, which are known as digits, are numbered 0 through 9. Based on the basic value of its digits, different types of number systems exist.
Awad claims that when m is a negative integer and n is a positive integer, n - m is always negative.
The above claim is false because subtracting a negative integer always results in an addition because two negatives equal a positive.
For example, n is 6 and m is -2; 6 -(-2) will equal 6 + 2 = 8.
Hence, the Awad'claims that "when m is a negative integer and n is a positive integer, n - m is always negative". which is false.
