Answer:

Step-by-step explanation:

$A (8, 2) = (x_1 ,y_1)\\ B(3,9) = (x_2,y_2)\\\\d = \sqrt{\left(x_2-x_1\right)^2+\left(y_2-y_1\right)^2}\\\\d =\sqrt{\left(3-8\right)^2+\left(9-2\right)^2}\\\\d=\sqrt{(5)^2+(7)^2}\\\\d=\sqrt{25+49}\\\\d=\sqrt{74}\\\\d = 8.6023\\\\d = 8.6$

One number is 5 times a first number. A third number is 100 more than the first number. If the sum of the three numbers is 779,

Harrizon [31]

Answer:

97, 485, 197

Step-by-step explanation:

<u>Given</u>:

First number = a
Second number = b
Third number = c

b = 5a
c = 100+a
a + b + c = 779

<u>Substituting b and c in the third equation:</u>

a + 5a + 100+a = 779
100 + 7a = 779
7a = 779- 100
7a=679
a= 679/7
a = 97
b= 5*97 = 485
c = 100+ 97 = 197

Does anyone know this?

weeeeeb [17]

Answer:

BC = 10.24

Step-by-step explanation:

You can use the Pythagoras theorem for this question

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

a = 8cm

b = ???

c = 13cm

We will solve for B (length BC)

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

$8^{2}$ + $b^{2}$ = $13^{2}$

Rearrange for b

$b^{2}$ = $13^{2}$ - $8^{2}$

$b^{2}$ = 105

b = $\sqrt{105}$

b = 10.24
