c) Solve for x given the perimeter of the trapezoid is 277 m.
how do i solve x

Answer:

x = 38

∠P = 26º

Step-by-step explanation:

The sum of the angle in a triangle is 180

x + (x + 78) + (x - 12) = 180

Combine like terms

3x + 66 = 180

Subtract 66 from both sides

3x = 114

Divide both sides by 3

x = 38

-----------------------

∠P = x - 12

∠P = 38 - 12

∠P = 26º

Answer:

Step-by-step explanation:

(x+78)+(x-12)+x=180

3x+66=180

3x=114

x=38

P=26

Answer:

x-intercept: -4

y-intercept: 24/5

Step-by-step explanation:

Firstly you have to isolate the y:

-6x + 5y = 24

5y = 6x + 24

y = (6x +24)/5

Now, just think about the graph: when the function touch the x-axis, the value of y is equal to 0, and when the function touch the y-axis, the value of x is 0, so just put they in the function:

y = (6•0 + 24)/5

y = 24/5

0 = (6x + 24)/5

5•0 = 6x +24

0 = 6x +24

-6x = 24

x = 24/-6

x = -4

Answer:

6

Step-by-step explanation:

3=x/2

Multiply both sides by 2

Answer:the correct answer is C

Step-by-step explanation:

Answer:

x = 4i - 1 or

x = 4i + 1

Step-by-step explanation:

(x+1)^2 = -4

x+1 = (+-)4i

x = +-4i - 1

==>

x = 4i - 1 or

x = 4i + 1

Fahad is taller with 31 centimeters

Step-by-step explanation:

1090mm=109cm

Fahad is taller than Fareed by 31 centimeters.

1090 mm = 109 cm

140 cm - 109 cm = 31 cm

Answer:

10 m building in Patrick's drawing would be of  0.5 cm

Step-by-step explanation:

Scale of Patrick's drawing is

1 inch = 10 meters

or 2.54 cm = 10 meters

1 cm = 3.94 m

In case of  Squidward the scale is 2 cm = 40 meters or

1 cm = 20 meters

So a 10 m building in Patrick's drawing would be of

0.5 cm

Answer:

13.5

Step-by-step explanation:  

Given: Patrick’s drawing uses a scale of 1 inch = 10 meters. Squidward made another scale drawing of the hotel with a scale of 2 cm = 40 meters.  

To find: How tall is the hotel on Squidward’s drawing?  

Formula: Height of the building = y × tan x + measurer's height  

Solution: The height of the building is calculated by using the formula. y = distance of the measurer from the building. x = the angle measured from the clinometer.

Answer:

1/3

Step-by-step explanation:

Total number of people who play sports in the Algebra 2 class:

[tex]21 - 9 = 12[/tex]

If there are 10 students who play Basketball, there are 2 students who ONLY play Baseball. If there are 9 students who play Baseball, there are 3 students who ONLY play Basketball.

So the number of students who play BOTH sports is:

[tex]12 - 2 - 3 = 12 - 5 = 7[/tex]

If 7 from the 21 Algebra 2 class students play BOTH sports, the probability is:

[tex]P = \frac{7}{21} = \frac{1}{3}[/tex]

Answer:

66 ft^2

Step-by-step explanation:

2 x 3 = 6

5 x 12 = 60

6 + 60 = 66

Answer:

A=A1 + A2

A= (l×w) + (l×w)

A= ((12-3)×5) + (3×(5+2))

A=66 ft^2

Answer:

yea im sure thats the answear

For lower cuboid

l=16m

b=9n

h=6m

For upper cuboid

l=9m

b=2m

h=6m

Note: volume of cuboid =l×b×h

total volume =lower cuboid +upper cuboid

=16*9*6+2*6*9=972m³

Answer:

Step-by-step explanation:

The volume is the sum of volumes of two rectangular prisms:

Answer:

114

Step-by-step explanation:

Answer:

Area = 115 yards

Step-by-step explanation:

If we look at this as two rectangles, you can see that the area of one is going to be 10yd multiplied by 9yd, which gives us 90yd. The other smaller rectangle will be 6yd multiplied by 4yd, which gives us 24yd.

Now, add the two areas back together to get the area of the whole shape and you get A=115yd.

Hope this helps!

Answer: 2/7

i’m pretty sure it’s 2/7

Answer:

2

7

Step-by-Step Explanation:

Answer:

86.6%

Step-by-step explanation:

1. Divide the amount of points Mary got from the test by maximum amount of points

26/30≈0.866

2.Multiply that by hundred

0.866*100=86.6

Answer: 86.6%

Answer:

1. If x and y are supplementary angles, then y is sometimes acute because supplementary angles are angles that add up to 180 degrees. So, y can be acute while x can be obtuse, y can be obtuse while x can be acute, or both can be right angles.

2. If x and y are complementary angles, then x is never obtuse. Complementary angles are angles that add up to 90 degrees, and obtuse angles are angles over 90 degrees, so it's impossible to have an obtuse angle as a complementary angle.  

Step-by-step explanation:

Answer:

1) Sometimes

2) Never

Step-by-step explanation:

1) you could have two angles add up to 180 degrees and one of them could be less than 90

example, x = 140° and y = 40°

2) if two angles are complementary then their sum is 90° so neither angle must be less than 90°, thereby making them both acute angles

Answer:

70

Step-by-step explanation:

(Not the most streamlined way but.)

Knowing that if he had 5 tests, and a mark of 85, we can determine the total average grade Bill received. 85*5=425

Then subtract the known grades

425-(90+85+100+80)=x

425-(355)=x

70=x

Bill would have scored 70 on that 5th test

Answer:

25.7m

Step-by-step explanation:

Pythagorean Theorem: a^2+b^2=c^2

28^2+b^2=38^2

784+b^2=1444

b^2=660

b=25.6904652 or 25.7m

Answer:

1293 soccer books

Step-by-step explanation:

The tricky part about questions like this is: how do I assign variables to the three types of book?

You get a clue from the sentence, "She sold 3 times as many copies of the soccer book as the baseball book."  The number of soccer books is being described by referring TO the number of baseball books.  Pick a variable and assign it to the item being REFERRED TO!

x = number of baseball books

Then  3x = number of soccer books.  The number of basketball books is the same, so 3x = number of basketball books.  Here's the list...

x = number of baseball books

3x = number of soccer books

3x = number of basketball books

The total of these is 3017, so

x + 3x + 3x = 3017

7x = 3017

x = 431

Ah!  But don't forget to look back at the question:  it asks for the number of SOCCER books!  That's 3x, so 3(431) = 1293.
