Answer:

122 degrees

Step-by-step explanation:

*A pentagon has a total of 540degrees

1st step: take all of the degrees and add them up:

105 + 90 + 86 + 137 = 418

2nd step: subtract the sum from 540:

540 - 418 = 122

The missing angle is 122 degrees

Answer:

∠ C = 122°

Step-by-step explanation:

The sum of the interior angles of a polygon is

sum = 180° (n - 2) ← n is the number of sides

Here n = 5, then

sum = 180° × 3 = 540°

Sum the given angles and equate to 540°

∠ C + 137° + 86° + 105° + 90° = 540 , that is

∠ C + 418° = 540° ( subtract 418° from both sides )

∠ C = 122°

Answer:

c=b

Step-by-step explanation:

b is not equal to c.

Answer:

$35 - 3b is greater or equal to $10

Step-by-step explanation:

Remember that:

     Dollars spent on an item = (cost of one item)*(number of items), so –

        Dollars spent on comic books = $3b

“Tracy has $35 to buy comic books and to pay for a movie ticket”   means

     (Money spent on comic books) + (money spent on movie ticket) ≤ $35

     (Money spent on comic books + $10 ≤ $35

                  $3b + $10 ≤ $35                           [just substituting values]

Now, we must modify the inequality, so remember the rules –

       $35 ≥ $3b + $10      [reverse right-to-left reverses the sense of the inequality;

             $35 is greater or equal to the total amount Tracy can spend]

       $35 - $3b  ≥ $10   [subtract positive 3b from both sides

                   keeps the sense of the inequality]

Answer:

Notice that the side length of the square is  38 m.

area of square  =  (side length)2  =  (38 m)2   =   1444 m2

Notice that the diameter of the circle is  38 m .

And its radius  =  diameter / 2   =   38m / 2   =   19 m

area of circle  =  pi * radius2  =  pi * (19m)2  =  pi * 361 m2   ≈   1133.54 m2

So......

area of shaded region  =  area of square - area of circle

area of shaded region  ≈       1444 m2     -  1133.54 m2

area of shaded region  ≈    310.46 m2

Step-by-step explanation:

Notice that the side length of the square is  38 m.

area of square  =  (side length)2  =  (38 m)2   =   1444 m2

Notice that the diameter of the circle is  38 m .

And its radius  =  diameter / 2   =   38m / 2   =   19 m

area of circle  =  pi * radius2  =  pi * (19m)2  =  pi * 361 m2   ≈   1133.54 m2

So......

area of shaded region  =  area of square - area of circle

area of shaded region  ≈       1444 m2     -  1133.54 m2

area of shaded region  ≈    310.46 m2

Answer:

I would say B The x-intercept of function p is less than the x-intercept of function q. tell me if you got it right.

Step-by-step explanation:

The correct answer is option B. The x-intercept of function p is greater than the x-intercept of function q.

The x-intercept is where the curve represented by the equation cuts the x axis. At that point the ordinate should be 0.

[tex]log_{2} (x-1)=0[/tex]

⇒ x= 2

The x-intercept of p(x) is 2

2^x-1 = 0

⇒x= 0

The x-intercept of q(x) is 0

So, we can see the  x-intercept of p(x) is greater than x-intercept of q(x)

Answer:

C, 8,634.86

Step-by-step explanation:

Starting with 8,591.69

2.51% of 8,591.69 is 215.651419

subtract that from 8,591.69 and you get 8376.038581

3.09% of 8376.038581 is 258.819592153

258.819592153+8376.038581=8634.85817315

8,634.86 is your final answer

Answer:

The statement is; True

Step-by-step explanation:

From the question, we have;

Rectangle ABCD is similar to Rectangle WXYZ

Therefore, rectangle ABCD can be obtained from rectangle WXYZ by multiplying by a scale factor given by the ratio of the corresponding sides of the two rectangles

Whereby side CD of rectangle ABCD is the corresponding side to side YZ of the rectangle WXYZ, we have;

The scale factor to obtain ABCD from WXYZ = CD/YZ

The scale factor for area is obtained by raising the scale factor of length to the power of 2

Therefore, the scale factor to obtain the area of rectangle ABCD from the rectangle WXYZ = (CD/YZ)²

∴ Area of ABCD = Area of WXYZ × (CD/YZ)²

From which we have;

(Area of ABCD)/(Area of WXYZ) = (CD/YZ)²

Therefore, the statement is true

Answer:

40 feet (after 1.5 seconds).

Step-by-step explanation:

The height h of the ball after t seconds is modeled by the function:

[tex]h(t)=-16t^2+48t+4[/tex]

And we want to determine the ball's maximum height.

Since the given function is a quadratic, the maximum height occurs at the vertex point.

For quadratics, the vertex point is given by the formulas:

[tex]\displaystyle \Big(-\frac{b}{2a},f\Big(-\frac{b}{2a}\Big)\Big)[/tex]

In this case, a = -16, b = 48, and c = 4.

Therefore, the t-coordinate at which the vertex occurs is:

[tex]\displaystyle t=-\frac{48}{2(-16)}=\frac{48}{32}=\frac{3}{2}[/tex]

So, the maximum height occurs after 1.5 seconds.

Then the maximum height will be:

[tex]\begin{aligned}\displaystyle h\Big(\frac{3}{2}\Big)&=-16\Big(\frac{3}{2}\Big)^2+48\Big(\frac{3}{2}\Big)+4\\\\ &=-16\Big(\frac{9}{4}\Big)+24(3)+4\\\\&=-4(9)+72+4\\\\&=40\text{ feet}\end{aligned}[/tex]

So, the maximum of the ball is 40 feet (after 1.5 seconds).

Explanation:

4²+4²≠8²

(4+4)²=8²

If you use PEMDAS you can find that 4²+4²=32 not 8² which equals 64

You can also find that (4+4)²=(8)²
