Answer: 9,2

Step-by-step explanation:

a+c=11

a=11-c

22(11-c) + 15c = 228

242-22c + 15c = 228

-7c=-14

C = 2 (two children)

Remember how a + c = 11

a + 2 = 11

A= 9

Prove using the Pythagorean theorem that AC is perpendicular to AB given points ????(−2, −2), ????(5, −2), and

Tems11 [23]

Answer:

$(BC)^2=(AC)^2+(AB)^2$ . It means AC is perpendicular to AB.

Step-by-step explanation:

Vertices of given triangle are A(−2, −2), B(5, −2), and C(−2,22).

Distance formula:

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Using distance formula we get

$AB=\sqrt{(5-(-2))^2+(-2-(-2))^2}=\sqrt{7^2}=7$

$BC=\sqrt{(-2-5)^2+(22-(-2))^2}=\sqrt{7^2+24^2}=\sqrt{625}=25$

$AC=\sqrt{(-2-(-2))^2+(22-(-2))^2}=\sqrt{24^2}=24$

According to Pythagoras theorem

$hypotenuse^2=perpendicular^2+base^2$

$(BC)^2=(AC)^2+(AB)^2$

Perpendicular = AC

Base = AB

It means AC is perpendicular to AB.

Hence proved.

Answer:

-0.3, -0.12, -0.03, 0.15

Step-by-step explanation:

-0.3 is the least because 0.3 = 0.30 and 0.30 is greater than 0.12, -0.12 is the second one because it is 0.12 behind 0 and is greater than -0.03. 0.15 is the last one because it is the only positive number therefore is the greatest one.

really hope this helps and isn't confusing but I'm pretty sure this is correct!
