Answer:

43. [tex]= \frac{.0045}{100}[/tex]

44. [tex]4\frac{9}{10}[/tex]

45. 8

Step-by-step explanation:

43. 0.45% = .0045

      [tex]= \frac{.0045}{100}[/tex]

44. [tex]\frac{1}{2}[/tex] • [tex]9\frac{4}{5}[/tex]

45. VIII = 8

Answer:

1. 30 student

2. 120 student's didn't vote

3. 7 quarters

Step-by-step explanation:

1. first, see how many games can be played:

45÷3 = 15

then, multiply the number of games by two because 2 students can play per game

15 • 2 = 30

2. first, figure out what percent of students did not vote:

  100 - 60 = 40%

  then, multiply the number of students total (300) by the decimal of the percent that did not vote to find the number of students who didn't vote:

    300 • .40 = 120 student's didn't vote

3. first, find how much 9 dimes is:

   1 dime = $0.10

   9 dimes = 9 • $0.10 = $0.90

  then, find how much money kerry had:

   $2.65 - $0.90 = $1.75

   finally, find out how many quarters kerry had by dividing the amount of money she had by the worth of a quarter:

   1 quarter = $0.25

    $1.75 ÷ $0.25 = 7 quarters

Answer:

  90°

Step-by-step explanation:

Any corner angle in a rectangle is 90°. Rotating the figure does not change that. Angle O' = 90°.

_____

Additional comment

No rigid transformation (translation, rotation, reflection) changes any angles. Nor does uniform dilation (the kind we usually study). Hence any rectangle that is translated, rotated, reflected, or dilated will still have all angles measuring 90°.

Answer:

£10.75

Step-by-step explanation:

£5.25 x 17 = 89.25

5 £20 notes is £100

£100 - £89.25 = £10.75

Answer: £10.75

Step-by-step explanation:

£5.25 x 17 = 89.25

5 £20 notes is £100

£100 - £89.25 = £10.75

Answer:

y = 3x - 7

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = 3 , then

y = 3x + c ← is the partial equation

To find c substitute (4, 5) into the partial equation

5 = 12 + c ⇒ c = 5 - 12 = - 7

y = 3x - 7 ← equation of line

Answer: x=6

Step-by-step explanation:

Given

5x-3=27

Add 3 on both sides

5x-3+3=27+3

5x=30

Divide 5 on both sides

5x/5=30/5

x=6

Step-by-step explanation:  Chemical signal is the type of communication which coordinates actions between neighboring cells . This ability originated in single cells organisms and was essential for the evolution of multicellular organisms because after a cell receives a message, it is transferred across the plasma membrane and changes are brought about within the cell in response to this message.

Answer:

assuming this is a rectangle:

VW=31

WX=19

YW=36.36

ZX=18.18

VX=36.36

Step-by-step explanation:

VW=VX

VW=31

WX=VX

WX=19

YW^2=19^2+31^2

YW^2=361+961

YW^2=1322

YW=36.36

ZX=1/2VX

ZX=18.18

VX=YW

VX=36.36

The measures of the rectangle are

a) The measure of VW = 31

b) The measure of WX = 19

c) The measure of YW = 36.36

d) The measure of ZX = 18.18

e) The measure of VZ = 18.18

The diagonal of a rectangle is calculated by the formula

From the Pythagoras Theorem , The hypotenuse² = base² + height² , and

Diagonal of a Rectangle = √ ( Length )² + ( Width )²

Given data ,

Let the rectangle be represented as VWXY

Now , the diagonals of the rectangle are VX and WY

Substituting the values in the equation , we get

The measure of VY = 19

The measure of XY = 31

Now , for a rectangle the opposite sides are congruent

So , the measure of VY = measure of WX

And , the measure of XY = measure of VW

On simplifying the equation , we get

The measure of WX = 19

The measure of VW = 31

And , the diagonal of the rectangle = √ ( Length )² + ( Width )²

Substituting the values in the equation , we get

The diagonal of the rectangle YW = √ ( 31 )² + ( 19 )²

The diagonal of the rectangle YW = √ ( 961 + 361 )

The diagonal of the rectangle YW = 36.359 ≈ 36.36

And , the measure of VX = measure of YW = 36.36

Now , the measure of ZX = measure of VZ = measure of VX / 2

So , the measure of ZX and VZ = 36.36 / 2 = 18.18

Hence , the diagonal of the rectangles is 36.36
