Sorry I can't give you a straight answer right now because I'm in a hurry but here is some help;

Step-by-step explanation:

Remember:

The actual area of the tennis court is 264 m²

First use the scale to find the actual dimensions of the court:

1 cm : 0.8m

30 cm in the drawing would be:

= 0.8 x 30

= 24 m outside

13.75cm in the drawing would be:

= 0.8 x 13.75

= 11 m outside

Area of a rectangle (which is what the dimensions resemble):

= Length x width

= 24 x 11

= 264 m²

In conclusion, the area of the tennis court is 264 m²

Step-by-step explanation:

The sum of the interior angles of a regular n-gon is given by the formula (n-2)180. Hence, in our case n=20 and we have the answer of 18(180)=3240 degrees.

Explanation:

The sum of the interior angles in a regular polygon with

n

sides is found through the formula

180

˚

(

n

−

)

Here,

n

=

20

, so the sum of the interior angles is

=

3240

˚

To find just one angle, divide

3240

˚

by

20

since all

20

angles are congruent.

Answer: I don't see a question, but the equation of the line that these points form is y = -x + 2

Step-by-step explanation:

y=-x+2

The points have a negative 1 as their slope. The y-intercept (the value of y when x=0) is 2

y = -x+2

Answer: 60 quarters and 40 dimes

Step-by-step explanation:

Step 1: Setup Coin Value and Coin Total Equation:

Coin Value Equation → 0.1d + 0.25q = $19.00 where d = dimes and q = quarters

Coin Total Equation → d + q = 100

Step 2: Rearrange Coin Total Equation in terms of dimes (d)

d = 100 - q  ← Revised Coin Total Equation

Step 3: Plug in our Revised Coin Total Equation for d into our Coin Value Equation:

0.1(100 - q) + 0.25q = $19.00

0.1(100) - 0.1(q) + 0.25q = $19.00

10 - 0.1q + 0.25q = $19.00

10 + (0.25 - 0.1)q = $19.00

10 + 0.15q = $19.00

Step 4: Subtract 10 from each side of the equation to isolate q

10 - 10 + 0.15q = $19.00 - 10

0.15q = 9

Step 5: Divide each side of the equation by 0.15 to isolate q

0.15q/0.15  =    9/0.15

q = 60

Step 6: Using our value for q, Solve for d using our Coin Total Equation:

d + 60 = 100

Subtracting 60 from both sides, we get d + 60 - 60 = 100 - 60

d = 40

Summarizing our word problem, we see that 60 quarters and 40 dimes add up to $19.00

Answer:  " 4 − 3a " .

________

Step-by-step explanation:

" 4 − a − a − a " ;

        = 4 − 1a − 1a − 1a " ;

        =  ?  " ;

________

Combine the "like terms" :

________

         →   " − 1a − 1a − 1a " ;

               = (− 1a − 1a) − 1a ;

               = ( − 2a) − 1a ;

               =  − 3a ;

________

Now, bring down the "4" ;

  and rewrite the expression:

________

        →  " 4 − 3a " ;

which cannot be simplified further.

________

The answer is:  " 4 − 3a " .

Answer:

21cm^2

Step-by-step explanation:

Formula for area of triangle = (base x height) / 2

in this triangle: base = 7        Height = 6

= (7 x 6) / 2

= 42 /2

= 21cm^2
