Answer:

<h2>∠Q corresponds with ∠Z</h2>

Step-by-step explanation:

  1. form a graph
  2. draw  Δ ZNM and ΔPQR on either side of the y- axis
  3. You reflect ΔZMN across the y- axis
  4. Then you translate said triangle up the graph
  5. The corresponding ∠'s will match and overlap.
  6. m∠Q ≅ m∠Z as well as being a corresponding triangle

Wha is the area of this
Korvikt [17]

Octagon, stop sign.

Eight isoscles triangles.   It looks like we're told the side is 9.9 and the height to the side (also called the apothem) is 12.

So each isosceles triangle has area  (1/2)(9.9)(12) and we have eight of them,

area = 8(1/2)(9.9)(12) = 475.2

Answer: 475.2

Usually we wouldn't be told 9.9 -- this is the baby version.  We know each of those isoscles triangles has unique angle 360/8=45 degrees, so the apothem and half the side of the octagon are a right triangle with acute angle 22.5 degrees.

The area of the right triangle with long leg 12, short leg x,

tan 22.5 = x/12 or

x = 12 tan 22.5

Twice that is what we're told is 9.9; let's check:

2x = 24 tan 22.5 = 9.941125496954282

The area of the little right triangle is

(1/2) 12 × 12 tan 22.5

and there are 16 of these

16 (1/2) 12 × 12 tan 22.5 ≈ 477.174

Convert the decimal number 183 into an equivalent 32 bit binary number. show all your work.
german
The bits are determined by repeated division by 2 to yield either 0 or 1.
 
183/2 = 91 rem 1  =>  1  (lowest bit)             2⁰
  91/2 = 45 rem 1  =>  1 (next higher bit)     2¹
  45/2 = 22 rem 1 => 1  (next higher bit)     2²
  22/2 = 11 rem 0  => 0 (next highrt bit)      2³
    11/2 = 5 rem 1    => 1 (next higher bit)     2⁴
     5/2 = 2 rem 1   => 1 (next higher bit)     2⁵
     2/2 = 1 rem 0   => 0 (next higher bit)    2⁶
     1/2 = 0 rem 1   => 1 (next higher bit)      2⁷
The next higher 24 bits have 0 in each bit.

For 32-bit system,
183 = 00000000 00000000 00000000 10110111 (with a space between bytes for readability)

Answer: 00000000000000000000000010110111

Doreen Schmidt is a chemist. She needs to prepare 32 ounces of a 13​% hydrochloric acid solution. Find the amount of 16​% soluti
klasskru [66]

Answer:

She should mix <u>20 ounces</u> of 16% solution and <u>12 ounces</u> of 8% solution.

Step-by-step explanation:

Given:

Doreen Schmidt needs to prepare 32 ounces of a 13​% hydrochloric acid solution.

Now, to find the amount she should mix of 16% solution and of 8% solution.

Let the 16% solution amount be x.

And let the 8% solution amount be y.

<em>So, the total ounces of solution:</em>

x+y=32

y=32-x .......(1)

Now, to solve the equation to get the solution she should mix:

16\%\ of\ (x)+8\%\ of\ (y)=13\%\ of\ (32)\\\\\frac{16}{100}\times x+\frac{8}{100}\times y=\frac{13}{100}\times 32

0.16x+0.08y=0.13\times 32

Substituting the value of y from equation (1) we get:

0.16x+0.08(32-x)=4.16

0.16x+2.56-0.08x=4.16

2.56+0.08x=4.16

Subtracting both sides by 2.56 we get:

0.08x=1.6

Dividing both sides by 0.08 we get:

x=20.

<em>The 16% solution amount = 20 ounces.</em>

Now, substituting the value of x in equation (1) we get:

y=32-x\\\\y=32-20\\\\y=12.

<em>The 8% solution amount = 12 ounces.</em>

Therefore, she should mix 20 ounces of 16% solution and 12 ounces of 8% solution.
