Answer:

×= 3/4

Step-by-step explanation:

3-11x = 9 + 5y - add 9 to both sides

9 + 3 - 11x = 5x - add 11x to both sides

9 + 3 = 5x + 11x

12 = 16x - divide 16 into both

12/16 - reduce

x = 3/4

Answer:

<h2>x=9√10</h2>

Given: A right triangle in which an altitude is drawn from the right angle vertex to the hypotenuse.

To find: 'x' the larger leg of triangle

Solution,

Using let rule for similarity in right triangle:

\frac{leg}{part}  =  \frac{hypotenuse}{leg}  \\ or \:  \frac{x}{27}  =  \frac{3 + 27}{x}  \\ or \: x \times x = 27(3 + 27) \\ or \: x \times x = 81 + 729 \\ or \:  {x}^{2}  = 810 \\ or \:  {x}^{2}  = 81 \times 10 \\ or \:  {x}  =  \sqrt{81 \times 10}  \\ or \: x =  \sqrt{81}  \times  \sqrt{10}  \\ or \: x =  \sqrt{ {(9)}^{2} }  \times  \sqrt{10}  \\  \: x = 9 \sqrt{10}

Hope this helps...

Good luck on your assignment..

3. Quincy deposits $400 in a new bank account that earns 4% simple interest per year. What
Illusion [34]

Answer:

$448

Step-by-step explanation:

We can use the simple interest formula for this:

A = P (1 + rt)

<em>P = initial balance</em>

<em>r = annual interest rate</em>

<em>t = time</em>

<em />

First, change 4% into its decimal form:

4% -> \frac{4}{100} -> 0.04

Now, lets plug in the values:

A=400(1+(0.04)(3))

A=448

The total amount in the account after 3 years will be $448

soldier1979 [14.2K]

As soon as you see "How many times . . .", that usually tells you that finding the answer involves <em>division</em>.  (It certainly does in this one.)

(1.2 x 10⁵) / (4.9 x 10³)  =  

(1.2/4.9) x (10⁵⁻³)  =

0.245 x 10²  =  <em>24.5 times</em>

It looks like  <em>B</em>  is the closest choice.
