grin007 [14]

Answer:

$\frac{9}{16}$

Step-by-step explanation:

Out of a total of 1, $\frac{15}{20}$ went to the fair and $\frac{12}{16}$ OF THOSE, bought atleast one book.

To find the fraction of students who bought at least one book, we will multiply both the fractions. That is the answer. Shown below:

$\frac{15}{20}*\frac{12}{16}\\=\frac{3}{4}*\frac{3}{4}\\=\frac{9}{16}$

Answer is $\frac{9}{16}$

Plz help asap 25 points

Ierofanga [76]

Answer:

$14.39

Step-by-step explanation:

The formula for continuous compounding of interest is:

A = Pe^(rt), were P is the initial dollar amount, A is the final amount, r is the interest rate as a decimal fraction, and t is the time in years.

Here we have $2109 = $500e^(10r) and need to solve for r.

To do this, take the natural log of both sides, obtaining:

ln 2109 = ln 500+ 10r.

Then 10r = ln 2109 - ln 500, and

ln 2109 - ln 500

r = --------------------------------------------

= .1439

The interest rate was 14.39%.

What is the slope of the line that passes through the points (3, 6)(3,6) and (1, 2) ?(1,2)

morpeh [17]

Answer:

-2

Step-by-step explanation:

Using the slope theorem:

$m=\frac{y_{1}-y_{0}}{x_{1}-x_{0}}$

$\frac{6-2}{1-3} = \frac{4}{-2} =-2$

To wash a window that is 4 meters off the ground, Rafi leans a 5-meter ladder against the side of the building. To reach the win

Andre45 [30]

Answer:

Base of the ladder is 3 meters away from the building.

Step-by-step explanation:

Let's use Pythagoras theorem to solve.

Pythagoras theorem says,

$a^{2} +b^{2} =c^{2}$

Here let horizontal distance is "a''

Vertical distance of window is 4 m

So, b=4

The Rafi leans 5 m ladder against the wall. So, c=5.

$a^{2} +4^{2} =5^{2}$

Simplify it

$a^{2} +16=25$

Subtract both sides 16

$a^{2} =9$

Take square root on both sides

a=±3

So, base of the ladder is 3 meters away from the building.
