Answer:

Angle ABC should equal 68.8 degrees.

Step-by-step explanation:

You begin by finding the angle ACB.  Which is 34.  This is because we are given angle ACD = 146.  ACD and ACB are supplementary angles so together they would equal 180.  180-146 = 34 hence why ACB is equal to 34.  Next, we need to find the values for y in order to solve for angle ABC, we can do this by using this simple equation.

(5y+3) + (4y+8) = 146.

The reason we use 146 is that the measure of all interior angles in a triangle is 180 and since we already know one of those angles is 34 then the remaining 2 angles would add up to equal 146.  Continuing on, using algebra we are able to understand that solution to this equation is y = 15.2 (repeating).

Finally, to solve for angle ABC we just need to replace y with the new value we found.  The equation for this is, 4(15.2) + 8 = angle ABC.  Through simple algebra, we are then able to find that angle ABC must equal 68.8

Answer: (v + 7)(v -3)

Step-by-step explanation:

(v +7)(v -3)

v x v = v^2

v x -3 = -3v

7 x v = 7v

7 x -3 = -21

v^2 -3v +7v -21 = v^2 +4v -21 = 0

Answer:

The answer is (v - 3)(v + 7).

Step-by-step explanation:

First, you have to elaborate it :

v² + 4v - 21 = 0

v² - 3v + 7v - 21 = 0

Next, you have to collect like terms :

v(v - 3) + 7(v - 3) = 0

(v - 3)(v + 7) = 0

Answer:

Step-by-step explanation:

The nth term of an Arithmetic sequence is expressed as;

Tn = a + (n-1)d

a is the first term

n is the numebr of terms

d is the common difference

If the 17th term has a value of 28, then

T17 = a + 16d = 28 ........ 1

If the 33rd term has a value of 78 then;

T33 = a+32d = 78 ...... 2

Solve simultaneously;

a + 16d = 28 ........ 1

a+32d = 78 ...... 2

Subtract

16d - 32d = 28-78

16d = 50

d = 50/16

d = 25/8

From 1;

a + 16d = 28

a + 16(25/8) = 28

a + 50 = 28

a = 28 - 50

a = -22

Get the 129th term

T129 = a + 128d

T129 = -22 + 128(25/8)

T129 = -22 +25(16)

T129 = -22+400

T129 = 378

Hence the 129th term is 378

Answer:

  2.4 inches

Step-by-step explanation:

A yard is 36 inches, so 2/3 yard is (2/3)(36) = 24 inches.

Each piece will be 1/10 of that length, so will be 24/10 = 2.4 inches.

Each piece will be 2.4 inches long.

Answer:

9/10

Step-by-step explanation:

Answer:

m=1/3

Step-by-step explanation:

Expand sin(u - v) using the angle sum formula for sine:

sin(u - v) = sin(u) cos(v) - cos(u) sin(v)

Recall the Pythagorean identity: for all x,

cos²(x) + sin²(x) = 1

Dividing both sides by cos²(x) gives

1 + tan²(x) = sec²(x)

(since tan(x) = sin(x)/cos(x) and sec(x) = 1/cos(x))

With 3π/2 < u < 2π, we expect sin(u) < 0, and with π/2 < v < π, we expect cos(v) < 0 and sin(v) > 0.

Solve for sin(u) :

sin²(u) = 1 - (4/5)²

sin(u) = - √(1 - 16/25)

sin(u) = - √(9/25)

sin(u) = -3/5

Solve for sec(v) :

sec²(v) = 1 + (-12/5)²

sec(v) = - √(169/25)

sec(v) = -13/5

Take the reciprocal of both sides to solve for cos(v) :

1/sec(v) = 1 / (-13/5)

cos(v) = -5/13

Solve for sin(v) :

sin²(v) = 1 - cos²(v)

sin(v) = √(1 - (-5/13)²)

sin(v) = √(144/169)

sin(v) = 12/13

Now put everything together:

sin(u - v) = (-3/5) (-5/13) - (4/5) (12/13) = -33/65

Answer:

90 % increase

Step-by-step explanation:

To find the percent increase, take the new number minus the original number

19-10 = 9

Divide by the original number

9/10 = .9

Change to a percent

.9 * 100 % = 90 % increase

Answer:

(final - initial / initial ) * 100

19 - 10/10 * 100

9/10 * 100

90 percent

Step-by-step explanation:

Answer:

x multiplied by 6x is 2400. 6x^2 = 2400. x^2=400, X=20

Answer:

± 20

Step-by-step explanation:

let one number be x then the other number is 6x and the product

x × 6x = 2400 , that is

6x² = 2400 ( divide both sides by 6 )

x² = 400 ( take the square root of both sides )

x = ± 20

Thus the number is 20 or - 20

Answer: Yes, your correct because the square root of 61 is 7.8, and that's inbetween 7 and 8
