The distance between the two points rounding to the nearest tenth<br> (-8,-6) and (-3,-4)
Lesechka [4]

Answer:

5.4

Step-by-step explanation:

To find the distance between two points, (x_1,y_1) and (x_2,y_2), plug them into the following equation:

d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\\d=\sqrt{(-3-(-8))^2+(-4-(-6))^2}

Two negatives make a positive

d=\sqrt{(-3+8)^2+(-4+6)^2}\\d=\sqrt{(5)^2+(2)^2}\\d=\sqrt{25+4}\\d=\sqrt{29}\\d=5.4

Therefore, the distance between the two points rounded to the nearest tenth is 5.4.

I hope this helps!

Answer:

Step 1 is wrong

Step-by-step explanation:

\frac{1}{4} r+ 2 = 10

\frac{r}{4}  + 2 = 10

\frac{r}{4}  = 10  -  2

\frac{r}{4}  = 8

r = 8 \times 2

r = 32

Relate Fractions, Decimals, and Money. Write the money amount as a fraction in terms of dollars. The problems are $0.66 and $1.0
ozzi
You convert a decimal to a fraction by putting the digits to the right of the decimal point over "1" followed by the same number of zeros. (Most folks learn this in 3rd or 4th grade.)

0.66 = 66/100 . . . . . 2 decimals, so the denominator is 100

Then you reduce the fraction by canceling common factors. It helps to know your times tables and divisibility rules. (Or you can have your calculator do it.)

0.66 = 66/100 = 33/50
1.00 = 100/100 = 1
