Answer:

The distance between the points is 6sqrt(5) units

Step-by-step explanation:

Use the distance formula:

d=sqrt([x2-x1]^2+[y2-y1)^2) where d is the distance between (x1,y1) and (x2,y2)

d=sqrt([-1-5]^2-[-7-5]^2)

d=sqrt([-6]^2-[-12]^2)

d=sqrt(36+144)

d=sqrt(180)

d=6sqrt(5) (since distance is positive)

Find the indicated term, 28th term: 0,-4, -8, -12...

Ivanshal [37]

0, -4, -8, -12, -16, -20, -24, -28, -32, -36, -40, -44, -48, -52, -56, -60, -64, -68, -72, -76, -80, -84, -88, -92, -96, -100, -104, -108

-108 is the 28th term. This is one way to do it (to visualize it the long way).

Hope this helps :)

Lin ran 2 3/4 miles in 2/5 of an hour. How far would Lin run in 1 hour?

hoa [83]

$\begin{gathered} 2\frac{3}{4}=\frac{8+3}{4}=\frac{11}{4} \\ \frac{11}{4}mi\to\frac{2}{5}h \\ xmi\to1h \end{gathered}$

Using cross multiplication:

$\begin{gathered} \frac{11}{\frac{4}{x}}=\frac{2}{5} \\ x=\frac{11}{4}\cdot\frac{5}{2} \\ x=\frac{55}{8}mi=6\frac{7}{8}mi \end{gathered}$

Convert a mixed number to a fraction:

$a\frac{c}{b}=\frac{a\cdot b+c}{b}$

A Nike shoe factory uses 3.5 lbs of leather to make four pairs of shoes.At this rate How many pairs of shoes will 5.25 lbs of le

Gre4nikov [31]

Answer:

6 pairs

Step-by-step explanation:

It is given

3.5 lbs = 4 pair

We want to know:

5.25 lb = HOW MANY PAIR? (let this be x)

Now, we can write two ratios and equate them, cross multiply and find x(the pair of shoes that can be made with 5.25 pounds of leather). The ratios and algebra is shown below:

$\frac{3.5}{4}=\frac{5.25}{x}\\3.5x=4*5.25\\3.5x=21\\x=\frac{21}{3.5}\\x=6$

Thus,

with 5.25 lbs of leather, 6 pairs can be made
