Answer:
1.94 in
Step-by-step explanation:
The arc length formula is s = rФ. Here, r = 5 in and Ф = 70° But in this formula the central angle, Ф, must be in radians:
70°(1 rad)
-------------- = 0.389 rad
180°
Thus, the arc length here is s = (5 in)(0.889 rad) = 1.94 in

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.

Step-by-step explanation:
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:
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
solve for x round to nearest tenth
Answer:
33.3
Step-by-step explanation:
tan A = opp/adj
tan 39° = 27/x
x tan 39° = 27
x = 27/(tan 39°)
x = 33.3

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

Use the distributive property to remove the parentheses.
- 4(5u - 3y-1)
Answer:
-20u + 12y + 4
Step-by-step explanation:
We have the equation -4(5u - 3y - 1) and are asked to use the distributive property to remove the parenthesis.
When using the distributive property, you have to multiply the number outside the parenthesis to all numbers inside the parenthesis, do as followed :
-4(5u - 3y - 1)
(5u(-4) -3y(-4) -1(-4))
-20u + 12y + 4

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:
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.
