Answer 30

Step-by-step explanation:

I Just had a Test and it asked me that and I got an 100

Answer:

Length of the rectangle is 8 in and the breadth is 8 in.

a. [tex]A=xy[/tex]

b. [tex]y=16-x[/tex]

Step-by-step explanation:

Length = x

Breadth = y

Area is given by [tex]A=xy[/tex]

Perimeter of rectangle is given by

[tex]2(x+y)=32\\\Rightarrow x+y=16\\\Rightarrow y=16-x[/tex]

The condition that x and must satisfy is [tex]y=16-x[/tex]

So, area is

[tex]A(x)=x(16-x)\\\Rightarrow A(x)=16x-x^2[/tex]

Differentiating with respect to x we get

[tex]A'(x)=16-2x[/tex]

Equating with zero

[tex]0=16-2x\\\Rightarrow x=\dfrac{16}{2}\\\Rightarrow x=8[/tex]

Double derivative of A(x)

[tex]A''(x)=-2[/tex]

So [tex]A''(x)<0[/tex] which means [tex]A(x)[/tex] is maximum at [tex]x = 8[/tex]

[tex]y=16-x=16-8\\\Rightarrow y=8[/tex]

So length of the rectangle is 8 in and the breadth is 8 in.

Answer:

Step-by-step explanation:

1). ∠7 ≅ ∠ 2 (alternate exterior)

m∠7 = m∠2 = 30°

2). ∠4 and ∠1 are supplementary angles

m∠1 = 180° - 72° = 108°

Answer:

[tex](\frac{x1 + x2}{2}, \frac{y1+y2}{2}[/tex])

Step-by-step explanation:

Answer:Answer/Step-by-step explanation:

Given that m<3 = 54°

a. <1, <2, and <3 are angles on a straight line. They add up to 180°.

m<3 is given as 54°, m<2 = 90°, therefore,

m<1 = 180 - (54 + 90) = 180 - 144

m<1 = 36°

b. <2 is indicated as a right angle. Therefore, m<2 = 90°

c. <1 and <4 are vertical opposite angles. Vertical angles are congruent, since m<1 = 36°, therefore, m<4 = 36°

d. <5 and <2 are vertical opposite angles. m<2 = m<5, therefore, m<5 = 90°

e. <6 and <3 are vertical opposite angles. m<3 = m<6, therefore, m<6 = 54°

f. m<7 + m<6 = 180° (same side interior angles are supplementary)

m<7 = 180 - m<6

m<7 = 180 - 54

m<7 = 126°

g. m<7 + m<8 = 180° (linear pair)

126° + m<8 = 180

m<8 = 180 - 126

m<8 = 54°

h. m<9 = 180 - m<8 (linear pair)

m<9 = 180 - 54

m<9 = 126°

i. m<10 = m<8 (vertical angles)

m<10 = 54°

j. m<11 = m<4 (alternate interior angles are congruent)

m<11 = 36°

k. m<12 = 180 - m<11 (linear pair)

m<12 = 180 - 36

m<12 = 144°

l. m<13 = m<11 (vertical angles)

m<13 = 36°

m. m<14 = m<12 (vertical angles)

m<14 = 144°

Step-by-step explanation:

Answer:

A. M<1 = 36°

B. M<2= 90°

C. M<4= 36°

D. M<5= 54°

E. M<6= 54°

F. M<7= 126°

G. M<8= 54°

H. M<9= 126°

I. M<10 = 54°

J. M<11 = 36°

K. M<12 = 144°

L. M<13= 36°

M. M<14 = 144°

Answer:

your answer is 234

Step-by-step explanation:

The total degree inside the triangle is 360.

Add 104 and 22 to gt 126, and subtract from 360 to get the angle value of x, which is 234 degrees.

Answer:

no

Step-by-step explanation:

the sum of 4+7+9+12=32

32/4= 8

8 is not part of the sequence. Therefore its not arithmetic.

Answer:

5y  = x + 11

Step-by-step explanation:

Given parameters:

  Equation of the line ;

           y  = -5x + 1

  Coordinates = (2, -1)

Find the equation of a line perpendicular;

Solution:

A line perpendicular to  y  = -5x + 1  will have slope that is a negative inverse of the given one.

Equation of a straight line is expressed as;

           y  = mx + c

y and x are the coordinates

m is the slope

c is the y-intercept

        So, the slope of the new line perpendicular is [tex]\frac{1}{5}[/tex] ;

Now let us find the y-intercept of the new line;

   x = -1 and y = 2

      2  = [tex]\frac{1}{5}[/tex] x (-1) + c

           c  = 2 + [tex]\frac{1}{5}[/tex]   = [tex]\frac{11}{5}[/tex]  

The equation of the new line is;

          y  =  [tex]\frac{1}{5}[/tex]x +  [tex]\frac{11}{5}[/tex]  

or multiply through by 5;

        5y  = x + 11

Answer:

4

Step-by-step explanation:

I divided 30/16 and got 1.875, then I knew that 7.5 would have to have the same answer. I did a process of elimination by dividing 7.5 by numbers at random and finally divided by 4 and got the answer. Another way to get the answer would be to cross multiply the equation.
