A small town currently has a population of 15,000. Each year the population decreases by 2.25%. What will the population be in 8 years
Answer: 12,503 people
Step-by-step explanation:
This is an exponential decrease so to find the population in 8 years you have to use a future value formula:
= Amount * (1 + rate) ^ number of years
= 15,000 ( 1 + (-2.25%)) ⁸
= 15,000 * (1 - 2.25%)⁸
= 12,503.32
= 12,503 people

Find the product. Express your answer as a mixed number in simplest form.
2 1/6 × 4 1/2
Answer: 1 1/2, 3/2, or 1.5
Step-by-step explanation: Convert expression into unproper fractions, 13/6, and 9/2. Then by changing 13/6 into a denominator with 2, you multiply and it equals 1 1/2.

Help please and thankyou :)
Answer:
1/2
Step-by-step explanation:
As you probably know 10 is double the size/amount of 5, but instead of just putting 2 you would put 1/2. That is because it is a scale factor of a scale drawing, which is not the same size and is supposed to be smaller because you can't draw a house on a paper that would fit it literally ;)
Hope this helps!

1/2 = 1/a + b/c make b the subject
Answer:
b = [tex]\frac{ac-2c}{2a}[/tex]
Step-by-step explanation:
Given
[tex]\frac{1}{2}[/tex] = [tex]\frac{1}{a}[/tex] + [tex]\frac{b}{c}[/tex]
Multiply through by 2ac to clear the fractions
ac = 2c + 2ab ( subtract 2c from both sides )
ac- 2c = 2ab ( divide both sides by 2a )
[tex]\frac{ac-2c}{2a}[/tex] = b
There's 2 questions here that need to be answered.
Find the value of each variable.
Answer:
5. x= 13 y= 18.4
6.
Step-by-step explanation:
question 5:
tan45=x/13
multiply both sides by 13 to get x by its self.
end up with 13×tan45 so put that in the calculator to get x
then you do cos45= 13/y
multiply by y on both sides.
end up with y×cos45=13
divide the cos45 by both sides
put 13/cos45 to get y
question 6:
sin30=4/x
multiply x on both sides
end with x×sin30 =4
divide sin30 on both sides
put 4/sin30 in a calculator to get x
same thing again but with tan30 ahaha
Will give 100 points;
In the U.S., from 2004-2015, the correlation coefficient for the relationship between the size of a cell phone data plan, x, and the number of text messages sent, y, is r =0.97. Describe what this means about the relationship between the data plan size and the number of text messages sent in the U.S.
Answer options:
- There is no correlation between the size of the data plan and the number of text messages in the US.
- There is a weak positive linear correlation between the size of a cell phone data plan and the number of text messages sent.
- There is a strong negative linear correlation between the size of a cell phone data plan and the number of text messages sent.
- There is a strong positive linear correlation between the size of a cell phone data plan and the number of text messages sent.
I'd appreciate if you included an explanation, but an answer is fine.
Answer:
D. There is a strong positive linear correlation between the size of a cell phone data plan and the number of text messages sent.Step-by-step explanation:
We have r = 0.97
Correlation coefficients whose magnitude are between 0.9 and 1.0 indicate variables which can be considered very highly correlated (as per below table)r = (0.9, 1.0) very highly correlated. r = (0.7, 0.9) highly correlated. r = (0.5, 0.7) moderately correlated. r = (0.3, 0.5) low correlation. r = (0, 0.3) little to no correlation.Same applies to negative side
Correct choice is
D. There is a strong positive linear correlation between the size of a cell phone data plan and the number of text messages sent.To explain it in very simple way, consider a linear equation:
y = mx + bNumber of text messages is the linear function of the data plan. r = 0.97 shows this relationship is almost a perfect line with positive slope.
- There is a strong positive linear correlation between the size of a cell phone data plan and the number of text messages sent is your answer

3n^3 - 12n^2 + 2n - 8
(show the work pls..)
Answer:
The answer will be ( n - 4 ) ( 3n² + 2 ).
Step-by-step explanation:
1) Factor out common terms in the first two terms, then in the last two terms.
[tex] {3n}^{2} (n - 4) + 2(n - 4)[/tex]
2) Factor out the common term n - 4.
[tex](n - 4)( {3n}^{2} + 2)[/tex]
Therefor, the answer is ( n - 4 ) ( 3n² + 2 ).

Step-by-step explanation:
Pi = 3.14 to find the radius of a circle we multiply the circumference and Pi. Then square it. So, 34.48x3.14 = 108.2672 then 108.2672² = 3734.94651 which rounds to 3734.95

9
12
Friend
4
8
Your friend sells tickets
Answer:
16
Step-by-step explanation:
If 3 x 4 = 12 then you need to do the same to the number 4 so 4 x 4 =16
Answer:
3 : 4 :: 12 : x proportion 3x = 48 product means/extremes Can you solve for x and answer?
(If not look below.)
Step-by-step explanation:
ratio: 3:4
so divide 12 by 3=4
and multiply 4 by 4=16
your friend sells 16 tickets
ratio is now 12:16
4 : 3 = 12 : x
x = 12 * 4 / 3 = 16

A plastic box has the dimensions shown. 2 square pyramids are stacked on their bases. The bases are 8 centimeters by 8 centimeters and the height of each pyramid is 7.5 centimeters. What is the volume of the box? 160 cm3 320 cm3 480 cm3 960 cm3
Answer:
the answer is 320
Step-by-step explanation:
just did the instruction
Answer:
320
Step-by-step explanation:
To find the volume, you multiply length times width times height, which is 3x1x2, which equals six. Whereas the basic formula for the area of a rectangular shape is length × width, the basic formula for volume is length × width × height.
Wow look at my full percent battery
Logan is taking a loan out to buy a $4000 right for his wife. He has two finance options listed below. Which should he choose? Option a- a five year loan with a %7 interest rate compounded quarterly l. Option b- an eight year loan with a 5.5% interest rate compounded annually
Answer:
The most convenient option for Logan is A, since he will pay a lower amount than if he chose option B.
Step-by-step explanation:
Given that Logan is taking a loan out to buy a $ 4000 right for his wife, and he has two finance options, Option A, which gives a five year loan with a% 7 interest rate compounded quarterly, and Option B, which gives an eight year loan with a 5.5% interest rate compounded annually, to determine which option should be chosen, the following calculation must be performed:
Option A:
X = 4,000 (1 + 0.07 / 3) ^ 5x3
X = 5,653.49
Option B:
X = 4,000 (1 + 5.5 / 1) ^ 8x1
X = 6,138.75
Thus, the most convenient option for Logan is A, since he will pay a lower amount than if he chose option B.
A jeweler has several boxes of earrings to ship to a store. Each box is a cube with a side length of 5 centimeters. The jeweler packs the boxes in a shipping container. The filled container has 4 layers, where each layer contains 7 rows and 10 columns of boxes. What is the volume of the shipping container?
Answer: [tex]35,000\ cm^3[/tex]
Step-by-step explanation:
Given
The earring box has a volume of [tex]a=5\ cm[/tex]
It is packed and loaded in the container which has 4 layers and each layer has 7 rows and 10 columns
We can say that each layer can hold [tex]7\times 10=70\ \text{boxes}[/tex]
The volume of each earring box is
[tex]V_o=a^3=5^3\\V_o=125\ cm^3[/tex]
Four layers can hold [tex]4\times 70=280\ \text{boxes}[/tex]
the container can hold 280 boxes
[tex]\therefore \text{Volume of container is}\ V=280V_o\\\Rightarrow V=280\times 125=35000\ cm^3[/tex]
