5/8 because 1= 8/8.
8/8-3/8 is 5/8 :)

Alicia can row 6 miles downstream in the same time it takes her to row 4 miles upstream.She rows downstream miles/hour faster th

disa [49]

Answer:

Option D. 9 mi/hr downstream, 6 mi/hr upstream

Step-by-step explanation:

The complete question is

Alicia can row 6 miles downstream in the same time it takes her to row 4 miles upstream. She rows downstream 3 miles/hour faster than she rows upstream. Find Alicia’s rowing rate each way

Define the variables

Let

x -----> Alicia's rowing rate downstream in miles per hour

y ----> Alicia's rowing rate upstream in miles per hour

we know that

The rate is equal to the distance divided by the time

The time is equal to the distance divided by the rate

we have

$\frac{6}{x}=\frac{4}{y}$

$4x=6y$

$x=1.5y$ -----> equation A

$x=y+3$ ----> equation B

equate equation A and equation B

$1.5y=y+3$

$1.5y-y=3$

$0.5y=3$

$y=6$

Find the value of x

$x=1.5(6)=9$

therefore

Alicia's rowing rate downstream is 9 mi/h

Alicia's rowing rate upstream is 6 mi/h

(3x+1) ^1/3=4. Pls show me the steps to do it.

Ymorist [56]

Answer:

x = 21

Step-by-step explanation:

(3x+1) ^1/3=4 means that the 1/3 is an exponent that can be rewritten as a cube root.

You can bring the cube root to the other side of the equation.

1. I chose to bring it to the other side of the equation, making it a cube.

(3x+1) ^1/3 = 4

(3x+1) = 4^3

(3x+1) = 4 * 4 * 4

(3x+1) - 1 = 64 - 1

3x/3 = 63/3

x = 21

You save $3,260.00 in a savings account earning a 3.55% APR compounded monthly. How much is the total interest earned by the end

Georgia [21]

Answer:

$29.02

Step-by-step explanation:

We will use compound interest formula to find the amount of interest after 3 months.

$A=P(1+\frac{r}{n})^{nT}$ , where,

A= Amount after T years.

P= Principal amount.

r= Annual interest rate in decimal form.

n= Number of times interest is compounded per year.

T= Time in years.

Let us convert our given interest rate in decimal form.

$3.55\%=\frac{3.55}{100}=0.0355$

Let us convert our given time in years.

$3\text{ months}=\frac{3}{12}\text{ years}=0.25\text{ years}$

Let us substitute our given values in above formula.

$A=3260(1+\frac{0.0355}{12})^{12\times 0.25}$

$A=3260(1+0.0029583333333333)^{3}$

$A=3260(1.0029583333333333)^{3}$

$A=3260\times 1.0089012810988858948$

$A=3289.018176382368017048$

We will use formula $A=P+I$ to find the amount of interest.

$3289.018176382368017=3260+I$

$3289.018176382368017-3260=I$

$29.018176382368017=I$

$I\approx 29.02$

Therefore, the total interest earned by the end of the third month will be $29.02.
