Answer:

98

Step-by-step explanation:

angles 1 and 2 are congruent, the lines in each side of the shape prove this.

another way to solve if you are not sure is to subtract all of the numbers from 360. all quadrilaterals equal 360 degrees, so if you subtract each of the three angles from 360, you will be left with the last angle.

360-120-44-98=98

The first table represents a linear function

The second table represents an exponential function

Answer:

Step-by-step explanation:

a+c=62, c=62-a

7a+3.5c=364, using c found above gives you

7a+3.5(62-a)=364 expand left side

7a+217-3.5a=364 group like terms on left side

3.5a+217=364 subtract 217 from both sides

3.5a=147 divide both sides by 3.5

a=42, since c=62-a

c=62-42=20

So 20 children and 42 adult tickets were sold.

Answer:

[tex]x=4[/tex]

Step-by-step explanation:

By the Triangle Proportionality Theorem:

[tex]\displaystyle \frac{x}{12}=\frac{x+1}{15}[/tex]

By cross-multiplication:

[tex]\displaystyle 12(x+1)=15(x)[/tex]

Distribute:

[tex]12x+12=15x[/tex]

Subtract 12x from both sides:

[tex]12=3x[/tex]

Hence:

[tex]x=4[/tex]

Answer:

4

Step-by-step explanation:

The first thing you should notice is that the triangles (the smaller one and the larger one) are similar due to angle-angle similarity (the top angle equals itself, and because the bases are parallel lines cut by a transversal, the base angle of the bigger triangle is equal to the corresponding base of the smaller triangle.

Similar triangles' corresponding sides have equal ratios to one another. That means we can set up an equation: side of smaller triangle ÷ corresponding side of larger triangle = other side of smaller triangle ÷ corresponding side of larger triangle. We plug the values given to us and can change this equation to:[tex]\frac{x}{x + 12} = \frac{x + 1}{x + 16}[/tex] **

We now multiply both sides of the above equation by [tex](x + 12)(x + 16)[/tex] to get: [tex]x(x + 16) = (x + 1)(x + 12)[/tex]

[tex]x^{2} + 16x = x^{2} + 13x + 12[/tex]

[tex]3x = 12[/tex]

[tex]x = 4[/tex]

That means our answer, for the value of x, is 4

** Make sure you don't say [tex]\frac{x}{12} = \frac{x + 1}{15}[/tex], because those aren't the sides of the larger square.

Answer:

D

Step-by-step explanation:

Answer:

3 x d = 45

Step-by-step explanation:

d = 15

Multiply 3 x d which d equals 15 and multiply 3 x 15 = 45. So d = 15

Answer:

45 = 3d

d = 15

Product means the numbers are being multiplied together

Since it is 3 and Diego's score (d) it would be 3d

Whatever is being multiplied to d would be 45

15 x 3 = 45

That would complete the equation

Answer:

Step-by-step explanation:

A)

(22+12)/2 = [17]                 (12+17)/2 = [14.5]                 (17+14.5)/2 = [15.75]

B)

(10.5*2) - 5 = [16] ......... NOT 13

1. The  Complete Sequence is 2, 22, 12, 17, 14.5, 15.75.

2. The second term is 16.

A grouping of numbers in a specific order is known as a sequence. On the other hand, a series is described as the accumulation of a sequence's constituent parts.

Given:

1. 2  22  12   _  _  _

So, the rule is ( sum of consecutive terms) /2

Then, the fourth term is

= (22+12)/2

= 17

and, fifth term is

=(12+17)/2

= 14.5

and, sixth term is

= (17+14.5)/2

= 15.75

So, the Complete Sequence is 2, 22, 12, 17, 14.5, 15.75

2. First term =5 and 3rd term = 10.5

Again, third term = ( 5 + x ) /2

21 = 5 + x

x = 16

A is the answer

Step-by-step explanation:

Answer:

a) Given that w=81 and k = 0.375 then r = 6

b)  Given that s=27 and k = 224 then w=32

Step-by-step explanation:

Step(i):-

Given that W varies directly as r³

      ⇒ w∝r³

    ⇒   w = kr³

where 'k' is proportionally constant

given that w= 24 and r =4

     ⇒  24 = k (4)³

     ⇒ k = [tex]\frac{24}{64}[/tex]

    ⇒ k = 0.375

Step(ii):-

Given that W varies indirectly as 's'

            w ∝[tex]\frac{1}{s}[/tex]

            W =k [tex]\frac{1}{s}[/tex]

where 'k' is proportionally constant

          28 = k ([tex]\frac{1}{8}[/tex])

        k = 28 × 8 = 224

Step(iii):-

a) Given that w=81 and k = 0.375

     w = kr³

   81 = 0.375 (r)³

   r³ = 216

  r = ∛216 =6

 r =6

b)

 Given that s=27 and k = 224

          W =k [tex]\frac{1}{s}[/tex]

         w = 224 ([tex]\frac{1}{27}[/tex])

        w = 32
