What is the value of y? (Angle Theorems)

Answer:

5x-1

Step-by-step explanation:

f(x) = 3x-2

g(x) = 2x+1

(f+g) (x) = 3x-2 + 2x+1

Combine like terms

            = 5x -1

Answer:

C. 5x - 1

Answer:

Given b=1.7 and ∠β=39°,

So

x = 2.70133

Answer:

A = 68

B = 44

Step-by-step explanation:

The sum of the angles of a triangle add to 180

A+B+C =180

x + x-24 +68 = 180

Combine like terms

2x+44 =180

Subtract 44 from each side

2x+44-44= 180-44

2x = 136

Divide by 2

2x/2 = 136/2

x = 68

A = x = 68

B = x-24 =44

Answer: I’m confused with A but I’m 100% sure B is 44 I hope this helped

Answer: $1,000

Step-by-step explanation:

We are trying to find 5% of 20,000. Always remember that the "of" can be changed to a multiplication, and that "percent" means per hundred.  So you will write (5/100) x 20,000 = 0.05 x 20,000 = $1,000.00

Answer:

The number 1 and 47

or 13 and 59

Answer:

16 and 62

Step-by-step explanation:

Two variables x and y. x < y.

y - x = 46

y = 46 + x

4x = y + 2

y = 46 + x in 4x = y + 2

4x + y = x + y + 46 + 2

4x + y - y = x + y - y + 46 + 2

4x = x + 48

4x - x = x - x + 48

3x = 48

3x ÷ 3 = 48 ÷ 3

x = 16

y = x + 46

y = 16 + 46

y = 62

Answer: 98.1

Step-by-step explanation:

Given: mass= 970 gm

Time = 14 min

rate of decay= 15.1% per minute.

Now, computing to get amount of element remaining after 14 minutes.

Formula; Element remaining=

Element remaining=

⇒ Element remaining=

⇒ Element remaining= ≅ 98.1 (nearest 10th of a gram)

∴ 98.1 element is still remaining after 14 minutes.

Answer:

6 feet by 5 feet by 4 feet

7 feet by 6 feet by 4 feet

Step-by-step explanation:

The surface are of rectangular prism = 140 ft²

Surface area of rectangular prism is given by :

A = 2(lw + lh + wh)

Using trial by error method :

6 feet by 2 feet by 3 feet

A = 2(6*2 + 6*3 + 2*3) = 72ft²

6 feet by 5 feet by 4 feet

A = 2(6*5 + 6*4 + 5*4) = 148 ft²

7 feet by 6 feet by 4 feet

A = 2(7*6 + 7*4 + 6*4) = 188ft²

8 feet by 4 feet by 3 feet

A = 2(8*4 + 8*3 + 4*3) = 136ft²

The length of each side of the square is (3x-2) units

The dimensions of the rectangle are (5x + 4y) and (5x -4y) units

From the question, we are to factor out the given expression for the area of the square

The expression is

9x² − 12x + 4

Factoring

9x² − 12x + 4

9x² −6x -6x + 4

3x(3x -2) -2(3x-2)

(3x -2)(3x -2)

Hence, the length of each side of the square is (3x-2) units

Part B:

The given expression is

25x² − 16y²

Factoring

25x² − 16y²

By difference of two squares, we get

(5x + 4y)(5x -4y)

Hence, the dimensions of the rectangle are (5x + 4y) and (5x -4y) units

Step-by-step explanation:

There are choices when it comes to color (3). Then there is the choice between a boy dog or a girl dog (2). Multiply the number of colors by the number of genders. (6)

When choosing a dog from random, you can either choose:

Brown/M

Brown/F

Black/M

Black/F

Yellow/M

Yellow/F

(This list is called the Sample Space, a list of all possible outcomes)

Because the text says that all types of dogs are found in even numbers, it would not matter if there was 6, 12, 18, ... amount of dogs.

When looking at this sample space, you can see that the chance of choosing a Yellow/F dog, is 1 in 6.
