What is the exact perimeter of the trapezoid?

Answer:

Step-by-step explanation:

(x+9)² + (y-6)² = 9²

Answer:

140°

Step-by-step explanation:

Three angle are labeled below the acre. The smallest angle is 3/8 as large as the 160 angle. Find the value of angle a

The value of the smallest angle is given as:

= 3/8 of the 160 angle

=3/8 × 160°

= 60°

The sum of the total angle = 360°

Hence:

360° = 60° + 160° + a

a = 360° - (60° + 160°)

a = 360° - 220°

a = 140°

Therefore, a = 140°

Answer:

(5, 1 )

Step-by-step explanation:

Given the 2 equations

3y - 2x = - 7 → (1)

5x + 3y = 28 → (2)

Rearrange (1) expressing 3y in terms of x by adding 2x to both sides

3y = - 7 + 2x

Substitute 3y = - 7 + 2x into (2)

5x - 7 + 2x = 28

7x - 7 = 28 ( add 7 to both sides )

7x = 35 ( divide both sides by 7 )

x = 5

Substitute x = 5 into either of the 2 equations and solve for y

Substituting into (2)

5(5) + 3y = 28

25 + 3y = 28 ( subtract 25 from both sides )

3y = 3 ( divide both sides by 3 )

y = 1

solution is (5, 1 )

Answer:

-(3y-2x= -7)

3y+5x= 28

-3y+2x= 7

3y+5x= 28

7x=35

7x/7= 35/7

x=5

5(5)+3y= 28

25+3y=28

3y= 28-25

3y=3

3y/3=3/3

y= 1

3y-2x= -7

3(1) -2x= -7

3-2x= -7

-2x= -7-3

-2x= -10

-2x/-2=-10/-2

x= 5

chekin

5x+3y=28

5(5)+3(1)=28

25+3=28

28=28

Answer:

  8) ΔCAB ~ ΔFDE; SSS

  9) ΔMNQ ~ ΔPNO; SAS

  10) ΔDBE ~ ΔABC; SAS

Step-by-step explanation:

8) The side ratios, shortest to longest, are ...

  6 : 8 : 10 = 9 : 12 : 15 = 3 : 4 : 5

so are the same for both triangles. Triangles CAB and FDE are similar by SSS.

__

9) MN/NQ = PN/NO = 6/5 = 12/10. The vertical angles between these corresponding sides are congruent. Triangles MNQ and PNO are similar by SAS.

__

10)  BD/BA = BE/BC = 21/28 = 24/32 = 3/4. The shared angle between the corresponding sides is congruent to itself. Triangles DBE and ABC are similar by SAS.

Answer:

270 seconds

Step-by-step explanation:

Melissa's time = x seconds

Abby's time = (x + 30) seconds

Abby walks at a speed of 8 feet per second, and Melissa walks at a speed of 9 feet per seconds.

But, speed = [tex]\frac{distance}{time taken}[/tex]

For Abby,

8 = [tex]\frac{distance}{(x + 30)}[/tex]

distance = 8(x + 30) ................. 1

for Melissa,

9 = [tex]\frac{distance}{x}[/tex]

distance = 9x ............. 2

From equations 1 and 2, for the same distance;

8(x + 30) = 9x

8x + 240 = 9x

x = 240 seconds

Abby's time = (x + 30)

                    = (240 + 30)

                    = 270 seconds

So that Abby has been walking for 270 seconds when both students had walked exactly the same distance.

The time taken is 270 seconds.

Given that,

Based on the above information, the calculation is as follows:

8(x + 30) = 9x

8x + 240 = 9x

x = 240

So Abby time should be

= 240 +  30

= 270

Answer:

Number 1: -8.7. Number 2: -2

Step-by-step explanation:

To find the first one, subtract 11 from 2.3.

2.3-11= -8.7 , so that's the answer for the first one.

To find the answer to the second one, just do -4+-2=-2, so that's the answer for the second one.

Answer: 32

Step-by-step explanation:

32 is the answer because of the number from division of one number by another two.

Answer:

greater

Step-by-step explanation:

the reason is because if you allow x to have a value that is less than 3,

[tex] \sqrt{x - 3} [/tex]

will produce a square root of a negative number, and the square root of a negative number requires the use of imaginary numbers, therefore limiting x to greater than or equal to 3 prevents this, also, consideration should be given to the fraction

[tex] \frac{3}{x + 2} [/tex]

if x has a value of -2 it causes the denominator of the fraction to be 0, the denominator should never be 0, by limiting x to greater than 3 to prevent the problem above you are already taking care of x not being able to be -2 since greater than 3 already excludes -2

x=7

Done!

Any questions just leave them in the comments and I will answer.

Answer:

Step-by-step explanation:

i think you do 34x + 12

bc it is a same side interior angle and i think that equals 180 and then you

34x+12=180

      -12  - 12

34x=       168
