Answer:

1/3

Step-by-step explanation:

So because of BODMAS / PEDMAS / whatever you call it, you do the brackets first.

(7-2) = 5

5 squared is 25

So 25 is on the top.

Then we do the bottom one. We do square/cubed/quadrupled numbers first, so 3 to the power of 4 is 81.

4+81=85

85-10=75

So the bottom number is 75.

25 / 75 is the fractions so simplified that would be 1/3

If BC = 5 and CD = 26, find AC.

Blababa [14]

Answer:

$AC=\sqrt{130}$

Step-by-step explanation:

AC is the geometric mean. Solve it using this proportion:

$\frac{BC}{AC}=\frac{AC}{CD}$

Now fill in the values we know:

$\frac{5}{AC}=\frac{AC}{26}$

Cross multiply to get

$(AC)^2=130$

That means that

AC = $\sqrt{130}$ , which, in decimal form is

AC = 11.40175425
