What is the distance between two points with coordinates at (8, 40) and (20, 5)?

Mathematics
1 answer:
Alchen [17]3 years ago

Answer:

37 units

Step-by-step explanation:

The two points form a right triangle so

a²+b²=c² so

(8-20)²(x values)+(40-5)²(y values)=c² (distance) so

12²+35²=c² so

144+1225=c²

1369=c²

c=37 units

7/12,  3/4,  4/7,  5/8,  4/7

Answer:  

Order from Least to Greatest

4/7    =       4/7     <       7/12    <    5/8   <   3/4  

Showing Work  

Rewriting as fractions if necessary:  

7/12, 3/4, 4/7, 5/8, 4/7  

The least common denominator (LCD) is: 168.  

Rewriting as equivalent fractions with the LCD:  

98/168, 126/168, 96/168, 105/168, 96/168  

Ordering these fractions by the numerator in order from least to greatest:  

96/168    =    96/168     <     98/168    < 105/168    < 126/168  

Therefore, your input in order from least to greatest is:

Answer   =======>   4/7    =   4/7    <    7/12    <     5/8    < 3/4


B):  1.35,   5/4,   1.349,  6/5, 7/6

Number of inputs ====>  5

Answer => Ascending Order:  Least to Greatest =====>  7/6, 6/5, 5/4, 1.349, 1.35



C):   0.819,  0.8199, 81/100, 815/1000

Number of Inputs  ======>    4

Answer  ==> Ascending order (Least to Greatest ====>    81/100, 815/1000, 0.819, 0.8199



D):    3  4/7, 245/70, 3.572, 90/29

Number of Inputs:  4

Answer ==>  Ascending Order(Least to Greatest) ==> 90/29, 245/70, 3.572, 3 4/7




Hope that helps!!!!                                              : )

Solve the system of equations -3x+7y=-18 and 4x-4y=8 by combining the equations.
Aleksandr-060686 [28]

Answer:

\huge \colorbox{red}{(x,y)=(-1,-3)}

Step-by-step explanation:

multiply first equation by 4 and second by 3 respectively:

\begin{cases} \displaystyle - 12x + 28y =  - 72 \\   \:  \: \displaystyle  \: 12x - 12y = 24 \end{cases}

combine the equations:

\underline{ \begin{cases} \displaystyle - 12x + 28y =  - 72 \\   \:  \: \displaystyle  \: 12x - 12y = 24 \end{cases}} \\  \displaystyle16y =  - 48

divide both sides by -48:

\displaystyle \:  \frac{16y}{16}  =  \frac{ - 48}{16}  \\ y =  - 3

substitute the value of y to the second equation

\displaystyle \: 4x - 4. - 3 = 8

simplify multiplication:

\displaystyle \: 4x  + 12 = 8

cancel 12 from both sides:

\displaystyle \: 4x =  - 4

divide both sides by 4

\displaystyle \:  \frac{4x}{4}  =  \frac{ - 4}{4}  \\ x =  - 1

therefore our solution is

\displaystyle (x,y)=(-1,-3)
