expression is greater han 100

8. incorrect, since it is the 3rd root, reverse it and get 3^3=27
answer is 27x^(3/5)

9. incorrect, the answer is 4x^(2/3) because pemdas says that the exponents before multiplication

The residents of a city voted whether to raise property taxes. The ratio of yes votes was 7 to 4. if there were 5425 yes votes, what was the total numbers of votes?

Answers

Answer: 8525

Step-by-step explanation

Let the total number votes = x

Ratio of yes votes = 7

Ratio of no votes. = 4

Total vote. = 11

Total number that voted for yes

= 5425

Therefore total number of vote casted.

7/11 x X = 5425

7x/11 = 5425

7x = 5425 x 11

7x = 59675

To find x , divide through by 7

x = 59675/11

= 8525

A rectangle has a length six inches less than twice its width. If the perimeter of the rectangle is 54 inches, find the dimensions.

Answers

Answer:

let the width of the rectangle be x inches

then the length would be 2x-6

as perimeter =2(l+b)

putting values in formula

perimeter = 2(2x-6+x)

p= 6x-12 but as perimeter p=54inches so

54=6x-12

54+12=6x

66=6x

x=66/6

x=11 inches

width is 11inches and length is 2x-6= 2(11)-6=22-6=16 inches

Algebra I

Simple Interest Rate Formula:
$\displaystyle A = P(1 + rt)$

A is the final amount
P is the principle amount
r is rate
t is time

Step-by-step explanation:

Step 1: Define

Identify given variables.

P = $3,400

r = 0.0825

t = 25

Step 2: Find Interest

[Simple Interest Rate Formula] Substitute in variables:
$\displaystyle A = 3400 \bigg[ 1 + 0.0825(25) \bigg]$
Evaluate:
$\displaystyle A = \boxed{10412.5}$

∴ the bank account will gain$7,012.50 and have a net balance of $10,412.50.

Final answer:

Using the formula for compound interest, we can find out that the sum of $3400, invested for 25 years at 8.25% annual interest compounded yearly, will amount to approximately $26358.85.

Explanation:

The question relates to calculating compound interest rather than simple interest. We're given $3400 as the principal, an annual interest rate of 8.25% and 25 years as the time period. We assume that the interest is compounded annually. Typically, we use the formula A=P(1+r/n)^(nt), where A is the amount of money accumulated after n years, including interest, P is the principal amount, r is the annual interest rate in decimal form, n is the number of times that interest is compounded per unit t, t is the time the money is invested for.

Applying Formula

In this situation, r = 8.25/100 = 0.0825, P = $3400, t=25, and since it's yearly compounded n=1. Therefore, the equation becomes A = $3400 * (1+0.0825/1)^(1*25). The eventual amount will be approximately $26358.85. Thus, $26358.85 will be in the account after 25 years to the nearest cent.

What is the distance between the points (10, –7) and (10, 9) on the coordinate plane?

Answers

Distance= sqrt((10-10)^2+(9-(-7))^2)=sqrt((0)+(16)^2)=sqrt(256)=16

The distance between (10,-7) and (10,9) is 16 square units because -7 in absolute value + 9 in absolute value is 16 square units

2 PointsIf y(x) = x - 2, which of the following is the inverse of Ax)?
O . F'(x) = 2 - x
O B. f'(x) = x-2
O c. f'(x) = 2x
OD. F'(x) = x+2

Answers

Answer:

Step-by-step explanation:

let y = x - 2 and rearrange making x the subject, that is

y = x - 2 ( add 2 to both sides )

y + 2 = x

now change x to $f^(-1)$ (x) and y back to x, thus

$f^(-1)$ (x) = x + 2 → D
