Step-by-step explanation:

The sum of two interior angles in a triangle is equal to an exterior angle that's supplementary to the third interior angle

2x - 2 = 45 + x

2x - x = 45 + 2

x = 47°

Answer:

x = 47

Step-by-step explanation:

Finding the third angle (y) of the triangle:

- Since angles on a straight line add up to 180:

2x -2 + y = 180

y = -2x + 2 + 180

= -2x + 182

Hence, the third angle of the triangle is -2x + 182.

Since all 3 angles of a triangle add up to 180°:

-2x + 182 + x + 45 = 180

-2x + x + 227 = 180

-2x + x = 180 - 227

-x = -47

x = 47

Hence, x = 47

Answer:

20 meters

Step-by-step explanation:

A construction company is starting to build a new house. They need to put tape around the site to begin. The new home site is 20 meters wide by 40 meter long rectangle. The company already has 100 meters of tape. How much more tape does the company need to tape the site?

We would have to find the perimeter of this rectangle

Perimeter fo a rectangle = 2L + 2W

In the above question,

L = Length = 40 m

W = Width = 20 m

Hence:

Perimeter = 2(40m) + 2(20m)

= 80m + 40m

= 120m

Hence, he would need 120 meters of tape

From the above Question, the company already has 100m

Hence, the amount of tape that the company needs more =

120m - 100m = 20 m

Step-by-step explanation:

Answer:

Angle D = m∠D= 50°

Step-by-step explanation:

In ΔCDE we are given: 3 angles

m∠C=(5x+18) ∘

m∠D=(3x+2) ∘

m∠E=(x+16) ∘ .

The sum of angles in a triangle = 180°

Hence:

m∠C + m∠D + m∠E = 180°

(5x+18)° + (3x+2)° + (x+16)° = 180°

5x + 18 + 3x + 2 + x + 16 = 180°

5x + 3x + x + 18 + 2 + 16 = 180°

9x +36= 180°

Subtract 36 from both sides

9x + 36 - 36 = 180° - 36°

9x = 144°

x = 144°/9

x = 16

From the above question, we are asked to find:angle D (m∠D )

Hence:

m∠D=(3x+2)°

m∠D=( 3 × 16 + 2)°

m∠D=(48 + 2)°

m∠D= 50°

Answer: The blue whale's weight is 150 times heavier than the narwhal's weight.

Step-by-step explanation:

Given: Weight of Blue whale = [tex]3\times10^5\text{ pounds}[/tex]

Weight of Narwhal = [tex]2\times10^3\text{ pounds}[/tex]

Number of times blue whale's weight  is heavier than the narwhal's weight = [tex]=\dfrac{\text{Weight of Blue whale}}{\text{Weight of Narwhal }}[/tex]

[tex]=\dfrac{3\times10^5}{2\times10^3}\\\\=1.5\times10^{5-3}\ \ \ [\dfrac{a^m}{a^n}=a^{m-n}]\\\\=1.5\times10^2\\\\=1.5\times100=150[/tex]

Hence, the blue whale's weight is 150 times heavier than the narwhal's weight.

Answer:

We conclude that Tim is correct when he says that the expression x² only yields values that are positive.

Step-by-step explanation:

Given the expression

x²

Putting x = 1 in the expression

x²= (1)² = 1

Putting x = -1 in the expression

x²= (-1)² = 1

Thus, the expression yields the same output '1' when we enter x = 1, and x=-1.

Putting x = 2 in the expression

x²= (2)² = 4

Putting x = -1 in the expression

x²= (-2)² = 4

Thus, the expression yields the same output '4' when we enter x = 2, and x=-2.

Putting x = 3 in the expression

x²= (3)² = 9

Putting x = -1 in the expression

x²= (-3)² = 9

Thus, the expression yields the same output '9' when we enter x = 3, and x=-3.

The reason why the expression x² only yields positive values because the expression is in the square form, and the square of any number will always yield a positive value, no matter whether the input number is negative or positive.

Therefore, we conclude that Tim is correct when he says that the expression x² only yields values that are positive.

-9p=60-72

-9p=-12

p=-12/-9

p=4/3

b) m =1/2

20k-5=8m

20k-5=8(1/2)

20k-5=4

20k=4+5

20k=9

k=9/20 or 0.45

c) k=18

p+1/3k-20=82

p+1/3(18)-20=82

p+6-20=82

p=82+20-6

p=96

Answer:

A right triangle is a triangle that has 90 degrees angle in one of its parts. You are given two points that have coordinate:

x1,y1= (-2, 4)

x2,y2= (-1,1)

To make the angle 90 degrees, there is two possible third point coordinate:

1. x1, y2 = (-2,1)

2. x2, y1= (-1,4)

The right triangle would be option C: (-2,1)

Option A and B is not a right triangle

Answer:

[tex]Each\ Weight = \frac{1}{4}[/tex]lb

Step-by-step explanation:

Given

[tex]Weights = \frac{3}{4}lb[/tex]

[tex]Bananas = 3[/tex]

Required

Determine the weight of each

To do this, we simply divide the total weight by the number of bananas.

[tex]Each\ Weight = \frac{3}{4}/3[/tex]

Convert to multiplication

[tex]Each\ Weight = \frac{3}{4} * \frac{1}{3}[/tex]

[tex]Each\ Weight = \frac{1}{4}[/tex]

Hence, each banana weighs 1/4 of a pound

Answer:

115.2

Step-by-step explanation:

Answer: 115.2

Step-by-step explanation:

What is 24% of 480?

Y is 24% of 480

Equation: Y = P% * X

Solving our equation for Y

Y = P% * X

Y = 24% * 480

Converting percent to decimal:

p = 24%/100 = 0.24

Y = 0.24 * 480

Y = 115.2

Answer:

v = -4

Step-by-step explanation:

2(3v - 5) = 2(v - 11) - 4

6v - 10 = 2v - 22 - 4

     +10          +10

6v = 2v -12 - 4

-2v   -2v

4v = -16

divide both sides by 4

v = -4

Hope this helps!!

The value of v = - 4.

We have the following equation -

2(3v - 5) = 2(v - 11) - 4

We have to find out the value of the variable v.

The solution of an equation is the value of variable for which the left hand side is equal to right hand side.

We have the following equation -

2(3v - 5) = 2(v - 11) - 4

2 x 3v - 2 x 5 = 2v - 2 x 11 - 4

6v - 10 = 2v - 22 - 4

6v - 10 = 2v - 26

6v - 2v = - 26 + 10

4v = -16

v = - 4

Hence, the value of v = - 4.

Answer:

x=y+v/b

Step-by-step explanation:

So first you have y=x-v/b. You want to isolate x, so subtract x from both sides. You'll get -x+y=-v/b. Next, you're going to want to subtract y to further isolate x now that it's on the left side. Now you'll have -x=-y-v/b. But you don't want x to be negative, so you can divide both sides by -1 to make x positive. Now you'll have x=y+v/b.
