Micah rows his boat on a river 4.48 miles downstream, with the current, in 0.32 hours. He rows back upstream the same distance,

against the current, in 0.56 hours. Assuming his rowing speed and the speed of the current are constant, what is the speed of the current?

A desk drawer contains the different-colored markers listed below.

Maksim231197 [3]

Answer:

<h2>total no of markers :36</h2>

in first condition

<h2>no of blue marksers :4</h2>

so probability:

$\frac{4}{36} = \frac{1}{9}$

same goes to the second condition

Use 3.14 for PI( π ) <br><br> Diameter: 5 ft <br> Formula: A= πr2

Liula [17]

Answer:

$\boxed {\boxed {\sf 19.625 \ ft^2}}$

Step-by-step explanation:

The area of a circle is found using this formula:

$a= \pi r^2$

We know the circle's diameter is 5 feet, but we don't know the radius. Remember the diameter passes through the center from one side to the other, while the radius connects the center and the side. Therefore, the radius is half the diameter.

r=d/2
r= 5 ft/2
r= 2.5 ft

We know the radius is 2.5 feet and we are using 3.14 for pi. Substitute the values into the formula.

$a= (3.14)* (2.5 \ ft)^2$

Solve the exponent.

(2.5 ft)²= 2.5 ft *2.5 ft=6.25 ft²

$a= (3.14)*(6.25 \ ft^2)$

Multiply.

$a=19.625 \ ft^2$

The area of the circle is <u>19.625 square feet.</u>

Drag the tiles to the boxes to form correct pairs. Not all tiles will be used. A car repair center services 920 cars in 2012. Th

OverLord2011 [107]

Answer:

N = 920(1+0.03)^4t

Step-by-step explanation:

According to the given statement a car repair center services 920 cars in 2012. The number of cars serviced increases quarterly at a rate of 12% per year after 2012.

Rate is 12 % annually

rate in quarterly = 12/4= 3%

We will apply the compound interest equation:

N=P( 1+r/n)^nt

N= ending number of cars serviced.

P= the number of cars serviced in 2012,

r = interest rate

n = the number of compoundings per year

t= total number of years.

Number of compoundings for t years = n*t = 4t

Initial number of cars serviced=920

The quarterly rate of growth = n=4

r = 3%

The growth rate = 1.03

Compound period multiplied by number of years = 920(1.03)^4t

Thus N = 920(1+0.03)^4t

N = number of cars serviced after t years...

How do Solve These?????????

svlad2 [7]

Answer:

The slope of the parallel lines would be the same but the slope of the perpendicular lines would be the reciprocal

Step-by-step explanation:

To find a reciprocal for 1, 3, 4, 5, and 9 (whole numbers) just put a 1 over the number to make it a fraction and for 2, 6, 7, 8, and 10 (fractions) just flip it.

For example 1 would be 1/10 and 2 would be 3/2
