In 1920, a woman had 4 daughters. In 1950, each daughter had 3 daughters. In 1980, each of their daughters had 3 daughters. Finally, in 2010, each of their daughters had 3 daughters.
How many daughters were born in 2010? Explain how you determined your answer.
Answer:
108
I determined my answer by multiplying 4 x 3 x 3 x 3 = 108
Step-by-step explanation:
daughters born in 1950 = 4 x 3 = 12
daughters born in 1980 = 12 x 3 = 36
daughters born in 2010 = 36 x 3 = 108

Answer:
x = 8√3
Step-by-step explanation:
Using the Pythagorean Theorem:
a² + b² = c²
x² + 8² = 16²
x² + 64 = 256
x² = 192
√x² = √192
x = √64 √3
x = 8√3
Brianna's teacher asks her which of these three expressions are equivalent to each other. which is equivalent
Answer:
Please specify what the three expressions are.
Step-by-step explanation:
From what I understand, you need to set the expressions equal to each other. For instance, if one is 2(x-3) and the other is 2x-6, you could write it as:
[tex]2(x-3)=2x-6[/tex]
Then, by evaluating it, you would get:
[tex]2x-6=2x-6[/tex] by distribution over subtraction.
[tex]2x-6+6=2x-6+6[/tex] by the additive property of equality
[tex]2x=2x[/tex] Simplify.
[tex]x=x[/tex] by the reflexive axiom.
Since x will always equal itself, 2(x-3) and 2x-6 are equivalent.
Therefore, if the expressions, once set equal to each other, result in the equation x=x, or any other expression in which one quantity equals itself, the two expressions are equal.
Sorry I could not be of more help, but you did not specify what the expressions were.
pls help me with this question guys, no links pls, thank you very much
Answer:
29.4
Step-by-step explanation:
mC = 180 - 46 - 105 = 29
By Law of Sines: c/sin C = a/sin A
19.8/sin 29° = a / sin 46°
19.8/0.484 = a/0.72
a = 29.45 ≈ 29.4

Teresa is investing $20,000 in an account with 4.3% interest rate that is compounded monthly. How much money will she have if she takes her money out after 8 years?
Answer:
Teresa will have $28,200 if she takes her money out after 8 years.
Step-by-step explanation:
To be able to find the answer, you have to use the formula to calculate the future value:
FV=PV(1+i/n)^(n*t)
FV=future value
PV=present value= $20,000
i=interest rate= 0.043
n=number of compounding periods per time unit= 12
t=time in years= 8
Now, you can replace the values on the formula:
FV=20,000*(1+(0.043/12)^(12*8)
FV=20,000*1.41
FV=28,200
According to this, the answer is that Teresa will have $28,200 if she takes her money out after 8 years.

work out giving your answer as a mixed number 4 1/6 + 2 3/4
The answer in the mixed fraction form is 6¹¹/₁₂
What is a mixed fraction?A fraction represented with its quotient and remainder is a mixed fraction. For example, 2 1/3 is a mixed fraction, where 2 is the quotient, and 1 is the remainder. So, a mixed fraction is a combination of a whole number and a proper fraction.
Given here, 4¹/₆+ 2³/₄ = 25/6 + 11/4
= 50+33 / 12
= 83/12
= 6¹¹/₁₂
Hence the answer in mixed fraction is 6¹¹/₁₂

Step-by-step explanation:
24 ÷ 44% = y ÷ 100%
Solve for y - To do so, we will use cross multiplication.

A business has a savings account that earns a 3% annual interest rate. At the end of 1996, the business had $4,000 in the account. The formula
F = p (1+r/100)
t is used to determine the amount in the savings account.
F is the final amount,
p is the initial investment amount,
r is the annual interest rate, and
t is the time in years.
To the nearest dollar, how much did the business initially invest in 1991?
A. $3,450
B. $3,455
C. $4,631
D. $4,637
Answer:
The amount the business initially invested in 1991 is approximately;
A. $3,450
Step-by-step explanation:
The question relates to investment and finance
The parameters given are;
The annual interest rate on the business savings account = 3%
The amount the business had in the account at the end of 1996 = $4,000
The given formula used to determine the final amount in the savings account, [tex]F = p \cdot \left(1 + \dfrac{r}{100} \right )^t[/tex]
Where;
F = The final amount
p = The initial (principal) investment
r = The annual interest rate
t = The time in years
Therefore, we have;
The required information = The initial amount, 'p', the business invested in 1991
The time in years, 't', from 1991 to 1996 = 1996 - 1991 = 5
∴ The time in years from 1991 to 1996, t = 5 years
The final amount in 1996, F = $4,000
r = 3%
Plugging in the values in the given equation gives;
[tex]4000 = p\cdot \left(1 + \dfrac{3}{100} \right )^5[/tex]
Therefore;
[tex]p = \dfrac{4000}{\left(1 + \dfrac{3}{100} \right )^5} = 3,450.43513754[/tex]
To the nearest dollar, the initial amount the business invested in 1991, p ≈ $3,450.

Answer:
600
Step-by-step explanation:
Well, first you need to make a proportion which will be [tex]\frac{x}{6,000} = \frac{10}{100}[/tex]
x is what we need to find
6,000 is the total people who voted
10% is the percent of 18 to 29 years old
and 100% represents the circle graph because all circle graphs equal 100%
First, we use the cross multiply method, for instance, 6,000×10=60,000
Next, divide 60,000÷100 which is 600.
Therefore there are 600, 18 to 29 year olds who voted in the election.
Ainsley works for the owners of a bookstore. Her starting salary was 24,500, and she gets a 3% raise each year. Write an equation in function notation to represent subsidy’s salary as a function of the number of years she has been working at the bookstore. What will Ainselys salary be when she begins her fourth year working at bookstore?
Answer:
if x is the number of years she is working that the equation would be: 24,500+x*((3/100)*24,500)
Step-by-step explanation:
For her 4th year x would be 4, so for the equation above x=4:
24500+4*((3/100)*24500)=27440
