lidiya [134]3 years ago
3 0

Answer:

<u>A.) 11%</u>

Step-by-step explanation:

<u>Step 1)</u> There are 9 favorable outcomes but only 1 outcome is possible, so that leaves us with a fraction of: \frac{1}{9}

<u>Step 2)</u> Then we need to turn this into a decimal to find the percentage:

1 ÷ 9 = 0.111111111...

<u>Step 3)</u> We now need to turn this into a percent:

0.11 x 100% = 11%

Question- Solve for a<br> 2a+b=x
kobusy [5.1K]

Answer:

a = (x - b)/2

Step-by-step explanation:

2a + b = x

-b         -b

2a = x - b

/2        /2

a = (x - b)/2

for ex:

x = 3

b = 2

a = ((3) - (2))/2 = 0.5

a = 0.5

2a + b = x

2(0.5) + 2 = 3

Altitudes AA1 and BB1 are drawn in acute △ABC. Prove that A1C·BC=B1C·AC
Sophie [7]

Answer:

See the attached figure which represents the problem.

As shown, AA₁ and BB₁ are the altitudes in acute △ABC.

△AA₁C is a right triangle at A₁

So, Cos x = adjacent/hypotenuse = A₁C/AC ⇒(1)

△BB₁C is a right triangle at B₁

So, Cos x = adjacent/hypotenuse = B₁C/BC ⇒(2)

From (1) and  (2)

∴  A₁C/AC = B₁C/BC

using scissors method

∴ A₁C · BC = B₁C · AC
