9) A bookstore sold 15 books in 5 days. At

1 answer:

8 0

1. Find the unit rate

15 books divided by 5 days = 3 books sold per day.

Since we are looking for how many days it would take the store to sell 21 bucks, we could do 21 (amount of books) divided by 3 (how much books is sold in a day).

Therefore, it will take a week / 7 days to sell 21 books.

Write the equation of a circle with the following pints in the picture using the completing the square method. Thanks

So hmm notice the picture below

you have the center, and a point on the circle... all you need is the radius

$\bf \textit{distance between 2 points}\\ \quad \\
\begin{array}{lllll}
&x_1&y_1&x_2&y_2\\
% (a,b)
&({{ 1}}\quad ,&{{ -2}})\quad 
% (c,d)
&({{ 3}}\quad ,&{{ -4}})
\end{array}\qquad 
% distance value
d = \sqrt{({{ x_2}}-{{ x_1}})^2 + ({{ y_2}}-{{ y_1}})^2}\leftarrow r$

then use that radius in the circle's equation

$\bf (x-{{ h}})^2+(y-{{ k}})^2={{ r}}^2
\qquad center\ ({{ h}},{{ k}})\qquad
radius={{ r}}$

Hey there!

if i am doing this correct it should be

17/50, let me explain!

.34 is 34/100 and both of these numbers are even, thus you can divide it by 2 which will give you 17/50

Choose the numbers that are terminating decimals. Select all that apply.

horsena [70]

Answer: A, C, and D

Step-by-step explanation:

A terminating decimal is a decimal that has an end. In other words, $\frac{1}{4} =0.25$ is one, but $\frac{1}{3} =0.3333...$ is not.
