Work Out The Size Of Angle Y

Answers

Answer 1

Answer:

Angle y= 108 degrees

Step-by-step explanation:

2x+16= 3x-12 (corresponding angles)

3x-2x=16+12

x=28

3(28)-12= 72

180-72=108 degrees

PLEASE HALP THIS IS DUE TODAY!!!!!

Abe can paint the room in 15 hours, Bea can paint 50 percent faster than Abe, and Coe can paint twice as fast as Abe. Abe begins to paint the room and works alone for the first hour and a half. Then Bea joins Abe, and they work together until half the room is painted. Then Coe joins Abe and Bea, and they work together until the entire room is painted. Find the number of minutes after Abe begins for the three of them to finish painting the room.

Answers

90 + 12/5 x 60=90 + 144 +100= 334

so 334 would be your answer

The number of minutes after Abe begins for the three of them to finish painting the room is; 344 minutes

We are told that Abe can paint the room in 15 hours.

Converting to minutes gives; 15 × 60 = 900 minutes

If the area of the room to be painted is x.

Then area painted per minute is; x/900

Now Bea paints 50% faster than Abe. Thus, rate bee can paint per minute is; 1.5x/900

Now,coe can paint twice as fast as Abe. Thus, rate coe can paint per minute is; 2x/900

Abbey works alone for the first hour and half. Thus, this is 90 minutes. Area covered by him in 90 minutes = (x/900) × 90 = x/10

Now, Bea joins Abe, and they work together until half the room is painted. Thus;

x/10 + (x/900)t + (1.5x/900)t = x/2

Multiply through by 900 to get;

90x + xt + 1.5xt = 450x

Divide through by x to get;

90 + t + 1.5t = 450

2.5t = 360

t = 360/2.5

t1 = 144 minutes

Now, Coe joins Abe and Bea, and they work together until the entire room is painted. Thus;

(x/900)t + (1.5x/900)t + (2x/900)t = x/2

Multiply through by 900/x to get;

t + 1.5t + 2t = 450

4.5t = 450

t = 450/4.5

t2 = 100 minutes

Thus, total time = 144 + 100

Total time = 244 minutes

A triangle has lengths 4,7,9 Is it a right triangle why or why not?

Answers

Answer:

No

Step-by-step explanation:

4,7,9 is not a right angle triangle. If it was a right angle triangle then it show work in the formula a^2+b^2=c^2. But 4^2+7^2 doesn't equal 9^2. The hypotenuse or c should be 8.02 to be a right angle triangle.

What is  multiplication?

In mathematics, multiplication is a method of finding the product of two or more numbers. It is one of the basic arithmetic operations, that we use in everyday life.

here, we have,

Explanation:

Before solving the problem, we should understand what is the length that corresponds to one notch in the graph.

We see that there are 3 notches between 0 and 6, and that the length of the notches is constant: so, each notch corresponds to the same length. Since we have 3 notches, the length of each notch is

6/3 = 2

now, we have,

Since the car is located at the first notch, it means that its position is:

x = 1*2 = 2

Hence, The solution is, c. 2, is the position of the car.

Answers

Answer:

A) 9

Step-by-step explanation:

First you need to find the measure of angle c

Since it's a quadrilateral, the interior angles add up to 360 degrees

Now there's two right angles and one 99 degree angle

Add those and subtract from 360

360 - (90+90+99) = 81

C = 81 degrees

However x is the root of c so root 81 is 9

<A and <B are supplementary angles. If m<A= (8x-25)° and m <B=(7x-5)° , then find the measure of <B. answer asap?​

Answers

Answer:

Step-by-step explanation:

∠A + ∠B = 180    {supplementary angles}

8x - 25 + 7x - 5 = 180    {bring the like terms together}

8x + 7x - 25 - 5 = 180   {add the like terms}

15x - 30 = 180    {add 30 to both the side}

15x = 180 +30

15x = 210          {divide both sides by 15}

15x/15 = 210/15

x = 14

∠B = 7x - 5 = 7*14 - 5

      = 98 - 5

 ∠B = 93°

Answers

Step-by-step explanation:

Step 1:   Set up the formula for the surface area of a regular pyramid.

SA = [tex]\frac{p*h}{2} + B[/tex]

where :

SA equals the total surface area of the pyramid,  p equals the perimeter of the base,   h equals the slant height of the pyramidB equals the area of the base.

Step 2:  Plug the perimeter of the base into the formula

you can calculate the perimeter by multiplying the length of one edge by the number of edges.

Step 3: plug the value of the slant height into the formula (it is not the perpendicular height)

Step 4: find the area of the base (depend on the shape of the base)

The value of x decreased by 80% is y and the
value of x increased by 200% is z. What is the
value of z-y?​

Answers

Answer:

The value of z-y is 14x/5

Step-by-step explanation:

The value of x decreased by 80% is → x - x * 80/100 = x - x*4/5 = x/5. This also equals to y → y = x/5.  (1)

The value of x increased by 200% is → x + x * 200/100 = x + 2x = 3x. This also equals to z → z = 3x.  (2)

If you substitute the values from the equation 1 and equation 2, the value of z - y → (3x) - (x/5) = 14x/5

3( 4x - 3) + 8 = 2x + 10x -1

Answers

Answer:

see below

Step-by-step explanation:

3( 4x - 3) + 8 = 2x + 10x -1

Distribute

12x - 9 +8 = 2x+10x -1

Combine like terms

12x - 1 = 12x - 1

Subtract 12x from each side

12x - 1 -12x = 12x - 1-12x

-1 = -1

This is true for all values of x

x = all real numbers

Answer:

All real numbers are solutions.

Step-by-step explanation:

3 ( 4x - 3 ) +8 = 2x + 10x - 1       Example 1:

12x - 9 + 8 = 12x  - 1                    3 ((4*1) -3) + 8 = (2*1) + (10*1) - 1

        - 12x = -12x                           3 ((4) - 3) + 8 = (2) + (10) - 1

      -9 + 8 = -1                                 ( 12 - 9 ) + 8 = 12 - 1

             -1 = -1                                            3 + 8 = 12 - 1

Example 2                                                       11 = 11

3 ((4*6) - 3) + 8 = (2*6) + (10*6) - 1

3 ((24) - 3) + 8 = (12) + (60) - 1

       72 - 9 + 8 = 72 - 1

              72 - 1 = 72 - 1

                    71 = 71
